技术领域Technical field

本申请涉及通信技术领域，尤其涉及一种无线承载建立、业务流的监测方法及装置。The present application relates to the field of communication technologies, and in particular, to a method and a device for establishing a radio bearer and monitoring a service flow.

背景技术Background technique

为满足多样化的业务需求，在移动通信技术中，采用了服务质量(quality of service，QoS)方案，该方案的做法为，针对各个业务对时延、带宽等的需求，建立与各个业务对应的QoS策略，从而，在某个业务进行的过程中，可以根据与该业务对应的QoS策略，向该业务提供相应的QoS保障。In order to meet the diversified business requirements, in mobile communication technology, a quality of service (QoS) solution is adopted. The approach of this solution is to respond to the needs of each service for delay, bandwidth, etc. Therefore, during the process of a certain service, a corresponding QoS guarantee can be provided to the service according to the QoS policy corresponding to the service.

在第五代移动通信技术(5th generation，5G)***中，业务的QoS保障是由终端设备、(无线)接入网络((radio)access network，(R)AN)以及用户面功能(user plane function，UPF)网元实现的。具体来讲，某个业务对应的数据包构成该业务的业务流(flow)，而QoS策略是基于该业务流进行的，因此在5G***中，也可以将业务流称为QoS流，在下文中将以QoS流为例进行说明。当会话管理功能(session management function，SMF)网元生成与该QoS流对应的QoS策略后，将该QoS策略发送给UPF网元以及AMF网元，然后由AMF网元发送给(R)AN网元，(R)AN网元再将该QoS策略发送给终端设备。(R)AN网元在接收该QoS策略后，会立即为该QoS流分配无线资源，从而在(R)AN网元与该终端设备之间建立相应的无线承载，UPF网元在接收该QoS策略后，根据该QoS策略对该QoS流执行计费和带宽控制等策略，从而保证该QoS流的时延和带宽等需求。In the 5th generation (5G) system, service QoS is guaranteed by terminal equipment, (radio) access network ((radio) access network ((R) AN)), and user plane functions (user plane) function (UPF). Specifically, a data packet corresponding to a service constitutes a service flow of the service, and a QoS policy is performed based on the service flow. Therefore, in a 5G system, a service flow may also be referred to as a QoS flow. In the following, The QoS flow will be described as an example. When a session management function (SMF) network element generates a QoS policy corresponding to the QoS flow, the QoS policy is sent to the UPF network element and the AMF network element, and then sent by the AMF network element to the (R) AN network. The (R) AN network element then sends the QoS policy to the terminal device. After the (R) AN network element receives the QoS policy, it will immediately allocate wireless resources to the QoS flow, thereby establishing a corresponding radio bearer between the (R) AN network element and the terminal device, and the UPF network element receives the QoS After the policy, policies such as charging and bandwidth control are performed on the QoS flow according to the QoS policy, so as to ensure the delay and bandwidth requirements of the QoS flow.

然而，由于QoS策略的发送时刻与该QoS流的初始数据包的传输时刻之间可能存在较大的时延，(R)AN网元根据该QoS策略为该QoS流分配的无线资源在该时延内将不会有业务数据传输，从而造成无线资源的浪费。However, because there may be a large delay between the time when the QoS policy is sent and the time when the initial packet of the QoS flow is transmitted, the radio resources allocated by the (R) AN network element for the QoS flow at that time There will be no service data transmission within the delay, thus causing waste of wireless resources.

为了更好地理解本申请实施例提供的技术方案，下面先介绍现有技术中根据QoS策略对QoS流进行QoS保障的流程。如图2所示，在现有技术中，根据QoS策略对QoS流进行QoS保障的流程如下：In order to better understand the technical solutions provided in the embodiments of the present application, the following first introduces the process of performing QoS guarantee on QoS flows according to QoS policies in the prior art. As shown in FIG. 2, in the prior art, a process for performing QoS guarantee on a QoS flow according to a QoS policy is as follows:

1、SMF网元从PCF网元获取与QoS流对应的QoS策略。1. The SMF network element obtains a QoS policy corresponding to the QoS flow from the PCF network element.

具体来讲，该QoS策略可以是SMF网元主动向PCF网元请求的，例如图1中的情景(Scenario)1，SMF网元接收终端设备发送的协议数据单元会话(protocol data unit session，PDU)建立请求，则SMF网元向PCF发送用于请求对应的QoS策略的信息，PCF网元在接收SMF网元发送的该信息后，则从统一数据库(unified data repository，UDR)中获取该终端设备的静态签约信息，根据该静态签约信息生成QoS策略，然后将该QoS策略发送给SMF网元。或者，该QoS策略也可以是由PCF网元主动发送的，例如图1中Scenario 2，PCF网元接收AF网元发送的用于对某个QoS流请求QoS保障的信息，或图1中的Scenario 3，PCF网元接收NEF网元发送的用于请求为某个QoS流进行QoS提升的信息，在这两种情境下，PCF网元将AF网元或NEF网元发送的信息转换为对应的QoS策略，然后将该QoS策略发送给SMF网元。Specifically, the QoS policy may be actively requested by the SMF network element to the PCF network element, for example, scenario 1 in FIG. 1, and the SMF network element receives a protocol data unit session (PDU) sent by the terminal device. ) Establishment request, the SMF network element sends information to the PCF to request the corresponding QoS policy. After receiving the information sent by the SMF network element, the PCF network element obtains the terminal from a unified data repository (UDR). The device's static subscription information generates a QoS policy based on the static subscription information, and then sends the QoS policy to the SMF network element. Alternatively, the QoS policy may also be actively sent by the PCF network element, such as Scenario 2 in FIG. 1, and the PCF network element receives the information sent by the AF network element for requesting QoS guarantee for a certain QoS flow, or in FIG. 1 Scenario 3. The PCF network element receives the information sent by the NEF network element for requesting QoS improvement for a certain QoS flow. In these two scenarios, the PCF network element converts the information sent by the AF network element or the NEF network element into a corresponding one. And then send the QoS policy to the SMF network element.

PCF网元可以通过预定义规则方式或动态规则方式，将QoS策略发给SMF。对于通过预定义规则方式发送QoS策略，SMF网元上预先配置有多种预定义规则，PCF网元只需将与该QoS策略对应的预定义规则的索引号，例如规则名等，下发给SMF网元即可；对于通过动态规则方式发送QoS策略，PCF网元需将该QoS策略的具体信息发送给SMF网元。The PCF network element can send the QoS policy to the SMF through a predefined rule method or a dynamic rule method. For sending QoS policies by using predefined rules, the SMF network element is pre-configured with multiple predefined rules. The PCF network element only needs to send the index number of the predefined rule corresponding to the QoS policy, such as the rule name, to the The SMF network element is sufficient. For sending the QoS policy in a dynamic rule manner, the PCF network element needs to send specific information of the QoS policy to the SMF network element.

2、SMF网元将QoS策略发送给UPF网元。2. The SMF network element sends the QoS policy to the UPF network element.

具体来讲，SMF网元将PCF网元发送的QoS策略进行处理后，才发送给UPF网元、(R)AN网元以及终端设备。需要注意的是，SMF网元给UPF网元、(R)AN网元以及终端设备的QoS策略可能互不相同，也可能与SMF网元从PCF网元接收的QoS策略不完全相同，例如，SMF网元发送给UPF的某些信息可能是PCF网元没有提供的，如QFI，QFI是SMF网元根据从PCF网元接收的QoS策略生成的，然后SMF网元会将该QFI发送给UPF、(R)AN网元以及终端设备。或者SMF网元不会将QoS策略中的所有信息都发送给UPF网元、(R)AN网元以及终端设备，例如，SMF网元不会将QoS策略中包含的分配保留优先级(allocation and retention priority，ARP)提供给UPF网元，SMF网元不会将QoS策略中包含的流描述信息发给(R)AN等。因此，当SMF网元获取该QoS策略后，则将该QoS策略中需要发送给UPF网元的内容发送给UPF网元，具体内容在此不作限制。Specifically, the SMF network element processes the QoS policy sent by the PCF network element before sending it to the UPF network element, the (R) AN network element, and the terminal device. It should be noted that the QoS policies of the SMF network element to the UPF network element, the (R) AN network element, and the terminal device may be different from each other, or may be different from the QoS policies received by the SMF network element from the PCF network element. For example, Some information sent by the SMF network element to the UPF may not be provided by the PCF network element, such as QFI. QFI is generated by the SMF network element based on the QoS policy received from the PCF network element, and then the SMF network element sends the QFI to the UPF. , (R) AN network elements and terminal equipment. Or the SMF network element does not send all the information in the QoS policy to the UPF network element, the (R) AN network element, and the terminal device. For example, the SMF network element does not retain the allocation priority contained in the QoS policy. retention (priority, ARP) is provided to the UPF network element, and the SMF network element does not send the flow description information contained in the QoS policy to the (R) AN and the like. Therefore, after the SMF network element obtains the QoS policy, the content in the QoS policy that needs to be sent to the UPF network element is sent to the UPF network element, and the specific content is not limited herein.

3、UPF网元接收SMF网元发送的QoS策略，则UPF网元存储接收的QoS策略，并使用接收的QoS策略对QoS流执行计费和带宽控制等控制策略。3. The UPF network element receives the QoS policy sent by the SMF network element, and the UPF network element stores the received QoS policy and uses the received QoS policy to perform control policies such as charging and bandwidth control on the QoS flow.

4、SMF网元将QFI以及QoS profile等QoS策略通过AMF网元发送给(R)AN网元。4. The SMF network element sends the QFI and QoS profile and other QoS policies to the (R) AN network element through the AMF network element.

5、(R)AN网元收到该QoS策略后，根据QFI、QoS profile等信息为QoS流分配无线资源和信道，实现QFI到无线资源的映射，进而与终端设备建立相应的无线承载。5. After receiving the QoS policy, the (R) AN network element allocates wireless resources and channels for QoS flows according to QFI, QoS profile, and other information, and realizes the mapping of QFI to wireless resources, and then establishes corresponding radio bearers with the terminal equipment.

6、SMF网元将QFI以及QoS rule等QoS策略通过AMF网元/(R)AN网元发送给终端设备。6. The SMF network element sends QFI and QoS rules such as QoS rules to the terminal device through the AMF network element / (R) AN network element.

7、终端设备收到该QoS策略后，根据QFI、packet filters、QoS rule等信息，实现业务数据流到QFI的映射，以及QFI到无线资源的映射，进而与(R)AN网元建立相应的无线承载。7. After receiving the QoS policy, the terminal device implements the mapping of service data flow to QFI and the mapping of QFI to wireless resources based on QFI, packet filters, QoS rules, and other information, and then establishes a corresponding relationship with the (R) AN network element. Wireless bearer.

在现有技术中，UPF网元、(R)AN网元以及终端设备在接收到QoS策略后，会立即根据该QoS策略执行相应的QoS保障，例如，在(R)AN网元侧，当(R)AN网元接收到QoS策略后，则立即根据该QoS策略为该QoS流分配无线资源，建立无线承载，如果该QoS流中无业务数据传输，则为该QoS流保留该无线资源，直至(R)AN网元接收由控制面发送的对该无线资源进行回收的指令，再根据该指令回收该无线资源。由于QoS策略的发送时刻与该QoS流对应的业务数据的发生时刻可能存在较大的时延，例如，SMF网元根据终端设备发送的PDU会话请求，向PCF网元请求获取与终端设备对应的QoS策略，并向UPF网元、(R)AN网元以及终端设备发送了QoS策略，而终端设备向SMF网元发送PDU会话请求的时机可能是在终端设备首次接入核心网的时候，在终端设备首次接入核心网时，终端设备可能还没有开始使用该业务，因此，可能并不会立即产生实际业务数据，从而(R)AN网元根据该QoS策略为该QoS流分配的无线资源在终端设备开始使用该业务之前的时间段内将不会有业务数据传输，造成无线资源的浪费。In the prior art, after receiving a QoS policy, the UPF network element, the (R) AN network element, and the terminal device will immediately perform corresponding QoS guarantee according to the QoS policy. For example, on the (R) AN network element side, when After the (R) AN network element receives the QoS policy, it immediately allocates radio resources to the QoS flow and establishes a radio bearer according to the QoS policy. If there is no service data transmission in the QoS flow, the wireless resource is reserved for the QoS flow. Until the (R) AN network element receives the instruction for recovering the wireless resource sent by the control plane, and then recovers the wireless resource according to the instruction. Because the sending time of the QoS policy corresponds to the time when the service data corresponding to the QoS flow occurs, for example, the SMF network element requests the PCF network element to obtain the QoS policy, and sent the QoS policy to UPF network element, (R) AN network element and terminal equipment, and the timing of terminal equipment sending PDU session request to SMF network element may be when the terminal equipment first accesses the core network, When a terminal device accesses the core network for the first time, the terminal device may not have started to use the service. Therefore, the actual service data may not be generated immediately, so the (R) AN network element allocates the wireless resources for the QoS flow according to the QoS policy. There will be no service data transmission in the time period before the terminal equipment starts to use the service, causing waste of wireless resources.

鉴于此，本申请实施例提供一种无线承载建立方法，以减少无线资源的浪费。In view of this, embodiments of the present application provide a method for establishing a radio bearer to reduce waste of radio resources.

The specific processing process will be described in detail below.

步骤302、SMF网元向PCF网元发送与该PDU会话对应的QoS策略请求，PCF网元接收该QoS策略请求。Step 302: The SMF network element sends a QoS policy request corresponding to the PDU session to the PCF network element, and the PCF network element receives the QoS policy request.

具体来讲，一个PDU会话中包含一个缺省的服务质量流(default QoS flow)和零到多个非保证比特速率服务质量流(Non-guaranteed Bit Rate QoS flow，non-GBR Qos flow)或保证比特速率服务质量流(Guaranteed Bit Rate QoS flow，GBR QoS flow)。其中所有未指定QoS策略的业务流或QoS策略与缺省的QoS流相同的业务流都在该缺省的QoS流上传输。当SMF网元接收终端设备发送的PDU会话建立请求后，可从PCF网元获取该PDU会话的缺省QoS策略和其他业务控制策略，业务控制策略可能包括计费和QoS策略等某业务具体的控制策略。SMF网元根据获取的业务QoS策略确定是否为该业务建立QoS流，若该业务的QoS策略与缺省的QoS流不同，那么SMF网元需为该业务创建不同于缺省的QoS流的新的QoS流来对该业务进行QoS保障。在本申请实施例中，将具备相同QoS策略的至少一个业务流称为QoS流。由于(R)AN网元对于non-GBR QoS流和GBR QoS流均需建立无线承载，但(R)AN网元还需要对GBR QoS流额外预留带宽资源，因此合理管理(R)AN网元上GBR QoS流的无线承载，对减少无线资源更有意义，在下面的介绍中，将以GBR QoS流为例进行说明。Specifically, a PDU session includes a default QoS flow and zero to multiple non-guaranteed bit rate quality-of-service flows (Non-guaranteed BitRate QoS flow, non-GBR Qos flow) or guarantees. Bit rate quality of service flow (Guaranteed Bit Rate QoS flow, GBR QoS flow). All service flows that do not specify a QoS policy or service flows with the same QoS policy as the default QoS flow are transmitted on the default QoS flow. After the SMF network element receives the PDU session establishment request sent by the terminal device, it can obtain the default QoS policy and other service control policies of the PDU session from the PCF network element. The service control policy may include a specific service such as charging and QoS policy. Control Strategy. The SMF network element determines whether to establish a QoS flow for the service according to the obtained service QoS policy. If the QoS policy of the service is different from the default QoS flow, the SMF network element needs to create a new QoS flow to provide QoS guarantee for the service. In the embodiment of the present application, at least one service flow having the same QoS policy is referred to as a QoS flow. (R) AN network elements need to establish wireless bearers for both non-GBR QoS flows and GBR QoS flows, but (R) AN network elements also need to reserve additional bandwidth resources for GBR QoS flows, so the (R) AN network is properly managed The radio bearer of the GBR QoS flow on the yuan is more meaningful for reducing the wireless resources. In the following description, the GBR QoS flow will be used as an example for illustration.

另外，在5G***中使用QFI来标识一个QoS流，QFI在一个PDU会话内唯一，多个不同的PDU会话可能具有相同的QFI，具有相同QFI的QoS流在(R)AN网元或者UPF网元上的流转发处理相同。In addition, in 5G systems, QFI is used to identify a QoS flow. QFI is unique within a PDU session. Multiple different PDU sessions may have the same QFI. QoS flows with the same QFI are in the (R) AN network element or UPF network. Stream forwarding processing on the element is the same.

步骤303、PCF网元从UDR网元获取终端设备1的静态签约数据。具体来讲，该静态签约数据为终端设备签约的业务相关数据，例如，可以是终端设备开户时的业务套餐数据，该业务套餐数据指明该终端设备缺省的计费带宽等策略，该业务相关数据中还可以包含针对某个业务的特定的QoS策略等，在此不作限制。Step 303: The PCF network element obtains the static contract data of the terminal device 1 from the UDR network element. Specifically, the static contract data is service-related data contracted by the terminal device. For example, the static contract data may be service package data when the terminal device opens an account. The service package data indicates a default charging bandwidth policy of the terminal device, and the service is related to the service. The data may also include specific QoS policies for a certain service, etc., which is not limited here.

步骤304、PCF网元根据静态签约数据获取相应的QoS策略，以及确定该QoS策略的生效模式。Step 304: The PCF network element obtains a corresponding QoS policy according to the static contract data, and determines an effective mode of the QoS policy.

一种示例，PCF网元从UDR网元获取终端设备1在接入核心网时的静态签约数据后，可以根据该静态签约数据中的业务需求生成对应的QoS策略，例如，该业务需求可以是不低于10Mbit/s的传输带宽的需求，则该业务对应的QoS策略中的GBR为10Mbit/s。由于该静态签约数据中可能包含需要对业务进行GBR QoS保障的QoS策略，在这种情况下，PCF网元也可以直接从静态签约数据中获取业务的QoS策略。As an example, after the PCF network element obtains the static contract data of the terminal device 1 when accessing the core network from the UDR network element, it can generate a corresponding QoS policy according to the service requirements in the static contract data. For example, the service requirements may be If the transmission bandwidth is not less than 10Mbit / s, the GBR in the QoS policy corresponding to this service is 10Mbit / s. Since the static contract data may include a QoS policy that requires GBR QoS guarantee for the service, in this case, the PCF network element may also directly obtain the QoS policy of the service from the static contract data.

在PCF网元获取该QoS策略后，还可以为该QoS策略设置其生效模式。在本申请实施例中，生效模式用于指示其他网元在接收到该QoS策略时是否立即根据该QoS策略执行相应的操作，例如，该生效模式可以用于指示(R)AN网元在接收到该QoS策略时立即为该GBR QoS流建立无线承载或者延迟为该GBR QoS流建立无线承载，当然，由于不同的网元根据该QoS策略执行的操作不同，在此就不一一举例了。After the PCF network element obtains the QoS policy, it can also set its effective mode for the QoS policy. In the embodiment of the present application, the effective mode is used to indicate whether other network elements immediately perform corresponding operations according to the QoS policy when receiving the QoS policy. For example, the effective mode may be used to indicate that the (R) AN network element is receiving. When the QoS policy is reached, a radio bearer is set up for the GBR QoS flow immediately or a radio bearer is set up for the GBR QoS flow. Of course, because different network elements perform different operations according to the QoS policy, no examples are given here.

例如，该生效模式可以通过迟滞属性标识表示，例如，可以将生效模式标记为Mode信息，当然，该生效模式也可以采用其他形式表示，在此不作限制，在下面的描述中，将以Mode信息为例进行介绍。Mode信息至少对应两种取值，其中的一种取值用于指示立即生效，也可以称为即将生效，其中的另一种取值用于指示延迟生效。例如，对于QoS策略是根据UDR网元中的静态签约数据获取的业务场景，由于在获取该QoS策略时可能并无业务数据传输，因此，只需要在业务数据发生时进行QoS保障即可，在这种情况下，PCF网元可以将Mode信息设置为延迟生效，在本申请实施例即为这种场景；而对于其他的业务场景，例如，对于QoS策略来源于AF网元的业务触发或NEF网元的能力开放触发场景，AF网元的业务触发场景例如在基于互联网协议多媒体***(internet protocol multimedia subsystem，IMS)的语音业务(voice over LTE，VoLTE)场景中，AF网元为特定的业务流请求QoS保障，NEF网元的能力开放触发场景例如第三方(over the top，OTT)向NEF网元发送用于为特定业务流请求QoS提升的请求的场景，在这些场景中，PCF网元获取该QoS策略时已经明确与该QoS策略对应的业务数据即将发生或已经发生，PCF网元可以将Mode信息设置为立即生效。Mode信息的取值指示立即生效，UPF网元、(R)AN网元以及终端设备在接收到该QoS策略后立即为与该QoS策略对应的GBR QoS流建立无线承载，Mode信息的取值指示延迟生效，UPF网元、(R)AN网元以及终端设备在接收到该QoS策略后不为该GBR QoS流建立无线承载，这样，UPF网元、(R)AN网元以及终端设备等网元只在有业务数据发生的情况下，为该业务数据对应的GBR QoS流建立无线承载，既可以满足业务数据对QoS的需求，又可以减少无线资源的浪费，尤其是对GBR QoS流的无线资源的浪费。For example, the effective mode can be represented by a hysteresis attribute. For example, the effective mode can be marked as Mode information. Of course, the effective mode can also be expressed in other forms, which is not limited here. In the following description, Mode information will be used. As an example. The Mode information corresponds to at least two types of values, one of which is used to indicate immediate effect, which can also be referred to as coming into effect, and the other of which is used to indicate delayed effect. For example, for a service scenario where the QoS policy is obtained based on the static contract data in the UDR network element, there may be no service data transmission when acquiring the QoS policy. Therefore, only QoS guarantee is required when service data occurs. In this case, the PCF network element may set the Mode information to be delayed to take effect, which is the scenario in the embodiment of the present application; for other service scenarios, for example, the service trigger or NEF of the QoS policy that originates from the AF network element The network element's capabilities are open to trigger scenarios. The AF network element's service trigger scenario is, for example, in the voice over voice (LTE) scenario based on the Internet protocol multimedia system (IMS). The AF network element is a specific service. Flow request QoS guarantee, NEF network element capability opening triggering scenarios, such as the scenario where a third party (over the top, OTT) sends a request to a NEF network element to request a QoS improvement for a specific service flow. In these scenarios, the PCF network element When obtaining the QoS policy, it is clear that the service data corresponding to the QoS policy is about to occur or has already occurred. The PCF network element can set the Mode information. It is effective immediately. The value indication of the Mode information takes effect immediately. After receiving the QoS policy, the UPF network element, the (R) AN network element, and the terminal device establish a radio bearer for the GBR QoS flow corresponding to the QoS policy. The value indication of the Mode information indicates The delay takes effect. After receiving the QoS policy, the UPF network element, the (R) AN network element, and the terminal device do not establish a wireless bearer for the GBR QoS flow. In this way, the network of the UPF network element, the (R) AN network element, and the terminal device, etc. Only when there is service data, it can establish a wireless bearer for the GBR QoS flow corresponding to the service data, which can meet the QoS requirements of the service data and reduce the waste of wireless resources, especially for the wireless transmission of GBR QoS flows. Waste of resources.

例如，该Mode信息可以通过一个比特实现，例如，该一个比特的取值为1，表示延迟生效，该一个比特的取值为0，表示立即生效，这样，Mode信息所占用的资源较少，且指示也较为清晰。当然，Mode信息也可以有其他实现形式，在此不作限制。For example, the Mode information can be implemented by one bit. For example, the value of this bit is 1, which means that the delay takes effect, and the value of this bit is 0, which means it takes effect immediately. In this way, the Mode information occupies less resources. And the instructions are clearer. Of course, the Mode information can also have other implementation forms, which is not limited here.

需要说明的是，Mode信息的取值可以由PCF网元设置，或者也可以携带在用于对业务流请求QoS保障或者QoS提升的业务请求中，例如，对于QoS策略来源于AF网元的业务触发或NEF网元的能力开放触发场景，该Mode的取值也可以携带在AF网元向PCF网元发送的用于为特定的业务流请求QoS保障的请求或NEF网元向PCF网元发送的用于为特定业务流请求QoS提升的请求中，发送给PCF网元，这样可以增加网络***的灵活性。在本申请实施例中不对Mode信息的取值的设置方式进行限制。It should be noted that the value of the Mode information can be set by the PCF network element, or it can also be carried in a service request for requesting QoS guarantee or QoS improvement for the service flow, for example, for services whose QoS policy originates from the AF network element. Trigger or NEF network element's ability to open the trigger scenario. The value of this mode can also be carried in the request sent by the AF network element to the PCF network element to request QoS guarantee for a specific service flow or sent by the NEF network element to the PCF network element. The request for QoS improvement for a specific service flow is sent to the PCF network element, which can increase the flexibility of the network system. In the embodiment of the present application, there is no limitation on the setting manner of the value of the Mode information.

另外，需要说明的是，Mode信息可以是QoS策略的一部分，包括在QoS策略中，例如，在承载QoS策略的信息字段中增加一个或多个比特来指示Mode信息的取值，而增加的比特也属于承载QoS策略的信息字段的一部分；或者，Mode信息与QoS策略也可以是两个彼此独立的信息，在此不作限制。In addition, it should be noted that the Mode information may be a part of the QoS policy and is included in the QoS policy. For example, one or more bits are added to the information field carrying the QoS policy to indicate the value of the Mode information, and the added bits are It also belongs to a part of the information field carrying the QoS policy; or, the Mode information and the QoS policy may also be two independent information, which is not limited herein.

步骤305、PCF网元向SMF网元发送该QoS策略和第二信息，SMF网元接收该QoS策略和第二信息。Step 305: The PCF network element sends the QoS policy and the second information to the SMF network element, and the SMF network element receives the QoS policy and the second information.

在本申请实施例中，第二信息用于指示延迟为GBR QoS流建立无线承载。由于PCF网元确定该Mode信息的取值指示延迟生效，因此，该Mode信息即为该第二信息，在下面的介绍中，将以Mode信息为例进行说明。其中PCF网元可以在不同时间点分别向SMF网元发送QoS策略和第二信息。In the embodiment of the present application, the second information is used to indicate a delay in establishing a radio bearer for the GBR QoS flow. Because the PCF network element determines that the value of the Mode information indicates that the delay is effective, the Mode information is the second information. In the following description, the Mode information will be used as an example for description. The PCF network element may send the QoS policy and the second information to the SMF network element at different time points.

步骤306、SMF网元将该QoS策略和Mode信息发送给UPF网元，UPF网元接收该QoS策略和Mode信息。Step 306: The SMF network element sends the QoS policy and Mode information to the UPF network element, and the UPF network element receives the QoS policy and Mode information.

具体来讲，SMF网元接收该QoS策略后，将对该QoS策略进行处理，例如，从接收的QoS策略中筛选出不需要发送给UPF网元的内容，从而得到处理后的QoS策略，然后将处理后的QoS策略和Mode信息发送给UPF网元，需要说明的是，QoS策略与Mode信息为两个独立的信息，SMF网元也需要将Mode信息转换成UPF网元能够识别的信息，在此不再赘述，这样，可以减少SMF网元的运算复杂度，当然，也可以将Mode信息携带在处理后的QoS策略中，在此不作限制。Specifically, after receiving the QoS policy, the SMF network element processes the QoS policy. For example, the SQoS network element filters the content that does not need to be sent to the UPF network element from the received QoS policy to obtain the processed QoS policy. Send the processed QoS policy and Mode information to the UPF network element. It should be noted that the QoS policy and Mode information are two separate pieces of information. The SMF network element also needs to convert the Mode information into information that can be identified by the UPF network element. This is not repeated here. In this way, the computational complexity of the SMF network element can be reduced. Of course, the Mode information can also be carried in the processed QoS policy, which is not limited here.

当然，SMF网元也可以采用其他方式向UPF网元发送该QoS策略和Mode信息，在此不作限制。Of course, the SMF network element may also send the QoS policy and Mode information to the UPF network element in other ways, which is not limited herein.

需要说明的是，在本申请实施例中，SMF网元向UPF网元或者其他网元发送的“该QoS策略”，应该理解为根据SMF网元从PCF网元接收的QoS策略得到的，例如，可能经过了筛选处理后得到的QoS策略，而不能理解为该QoS策略与SMF网元从PCF网元接收的QoS策略完全相同。It should be noted that, in the embodiment of the present application, the "this QoS policy" sent by the SMF network element to the UPF network element or other network elements should be understood as being obtained according to the QoS policy received by the SMF network element from the PCF network element, for example, , The QoS policy obtained after the filtering process may not be understood as the QoS policy exactly the same as the QoS policy received by the SMF network element from the PCF network element.

步骤307、UPF网元根据QoS策略进行相应的处理。Step 307: The UPF network element performs corresponding processing according to the QoS policy.

UPF网元从SMF网元接收Mode信息后，则将该QoS策略存储起来，并根据Mode信息的取值进行相应的处理。例如，若Mode信息的取值用于指示立即生效，则UPF网元可采用如图2所示的流程中的第3个步骤的处理方式，在此不再赘述，而若Mode信息的取值用于指示延迟生效，则当UPF在检测到该QoS流对应的业务数据后，再根据存储的该QoS策略对该业务数据进行如图2所示的流程中的第3个步骤的处理。After the UPF network element receives the Mode information from the SMF network element, it stores the QoS policy and performs corresponding processing according to the value of the Mode information. For example, if the value of the Mode information is used to indicate the immediate effect, the UPF network element may adopt the processing method of the third step in the process shown in FIG. 2, which is not repeated here. It is used to indicate that the delay is valid. After the UPF detects the service data corresponding to the QoS flow, it performs the third step in the process shown in FIG. 2 on the service data according to the stored QoS policy.

在本申请实施例中，该Mode信息的取值用于指示延迟生效，即，指示延迟为该GBR QoS流建立无线承载，则UPF网元识别与该GBR QoS流对应的业务数据，例如，从QoS策略中获取与该GBR QoS流对应的QFI，建立该GBR QoS流与QFI的映射关系，并通过QFI识别业务数据。In the embodiment of the present application, the value of the Mode information is used to indicate that the delay takes effect, that is, to indicate that the delay establishes a wireless bearer for the GBR QoS flow, and the UPF network element identifies the service data corresponding to the GBR QoS flow, for example, from A QFI corresponding to the GBR QoS flow is acquired in the QoS policy, a mapping relationship between the GBR QoS flow and the QFI is established, and service data is identified through the QFI.

需要说明的是，步骤301-步骤307为可选步骤，即，不是必须要执行的，例如，SMF网元中也可以预先存储QoS策略和Mode信息，SMF网元可直接执行步骤308，主动将该QoS策略和Mode信息发送给(R)AN网元，在此不作限制。It should be noted that steps 301 to 307 are optional steps, that is, they do not have to be performed. For example, the SMF network element can also store the QoS policy and Mode information in advance. The SMF network element can directly perform step 308 and actively The QoS policy and Mode information are sent to the (R) AN network element, which is not limited here.

步骤308、SMF网元将该QoS策略和Mode信息发送给(R)AN网元，(R)AN网元接收该QoS策略和Mode信息。Step 308: The SMF network element sends the QoS policy and Mode information to the (R) AN network element, and the (R) AN network element receives the QoS policy and Mode information.

SMF网元从PCF网元接收QoS策略后，对该QoS策略进行处理，例如，SMF网元根据该QoS策略生成QFI，并从该QoS策略中筛选出不需要发送给(R)AN网元的信息，得到处理后的QoS策略，然后将Mode信息和处理后的QoS策略发送给AMF网元，由AMF网元将Mode信息和该处理后的QoS策略发送给(R)AN网元。After receiving the QoS policy from the PCF network element, the SMF network element processes the QoS policy. For example, the SMF network element generates a QFI according to the QoS policy, and filters out the QoS policy that does not need to be sent to the (R) AN network element. Information, obtain the processed QoS policy, and then send the Mode information and the processed QoS policy to the AMF network element, and the AMF network element sends the Mode information and the processed QoS policy to the (R) AN network element.

需要说明的是，步骤308与步骤306中的处理过程相同，步骤308的处理过程可参见步骤306，在此不再赘述。It should be noted that, the processing procedure of step 308 is the same as that of step 306. For the processing procedure of step 308, refer to step 306, which is not repeated here.

步骤309、(R)AN网元根据Mode信息进行处理。Step 309: The (R) AN network element performs processing according to the Mode information.

具体来讲，(R)AN网元接收Mode信息和该处理后的QoS策略后，根据该Mode信息的取值进行相应的处理。例如，若Mode信息的取值用于指示立即生效，则(R)AN网元可采用如图 2所示的流程中的第5个步骤的处理方式，在此不再赘述；若Mode信息的取值用于指示延迟生效，则(R)AN网元暂不为该GBR QoS流进行资源分配，以及不为该GBR QoS流建立无线承载。Specifically, after receiving the Mode information and the processed QoS policy, the (R) AN network element performs corresponding processing according to the value of the Mode information. For example, if the value of the Mode information is used to indicate immediate effect, the (R) AN network element may adopt the processing method of the fifth step in the process shown in FIG. 2, which will not be repeated here. The value is used to indicate that the delay takes effect, then the (R) AN network element does not temporarily allocate resources for the GBR QoS flow, and does not establish a radio bearer for the GBR QoS flow.

在本申请实施例中，以该Mode信息的取值指示延迟生效为例，因此(R)AN网元可以保存该QoS策略，暂不为该GBR QoS流进行资源分配，以及不为该GBR QoS流建立无线承载。In the embodiment of the present application, the value of the Mode information indicates that the delay takes effect as an example. Therefore, the (R) AN network element can save the QoS policy, temporarily not allocate resources for the GBR QoS flow, and not for the GBR QoS. The flow establishes a radio bearer.

步骤310、SMF网元将该QoS策略和Mode信息发送给终端设备，终端设备接收该QoS策略和Mode信息。Step 310: The SMF network element sends the QoS policy and Mode information to the terminal device, and the terminal device receives the QoS policy and Mode information.

具体来讲，SMF网元从PCF网元接收QoS策略后，将对该QoS策略进行处理，例如，SMF网元根据该QoS策略生成QFI，并从接收的QoS策略中筛选出不需要发送给终端设备的内容，得到处理后的QoS策略，然后将Mode信息和处理后的QoS策略发送给AMF网元，由AMF网元将Mode信息和处理后的QoS策略发送给(R)AN网元，由(R)AN网元将Mode信息和处理后的QoS策略发送给终端设备，在这种情况下，AMF网元和(R)AN网元对接收的QoS策略和Mode信息透传，不进行处理。Specifically, after receiving a QoS policy from a PCF network element, the SMF network element processes the QoS policy. For example, the SMF network element generates a QFI according to the QoS policy, and filters out the received QoS policy and does not need to send it to the terminal. The content of the device obtains the processed QoS policy, and then sends the Mode information and the processed QoS policy to the AMF network element. The AMF network element sends the Mode information and the processed QoS policy to the (R) AN network element. The (R) AN network element sends the Mode information and the processed QoS policy to the terminal device. In this case, the AMF network element and the (R) AN network element transparently transmit the received QoS policy and Mode information without processing. .

需要说明的是，步骤310与步骤306中的处理过程相同，步骤310的处理过程可参见步骤306，在此不再赘述。It should be noted that the processing procedure of step 310 is the same as that of step 306. For the processing procedure of step 310, refer to step 306, and details are not described herein again.

步骤311、终端设备根据Mode信息进行处理。Step 311: The terminal device performs processing according to the Mode information.

终端设备接收Mode信息和进行格式转换后的QoS策略后，根据该Mode信息的取值的进行相应的处理。例如，若Mode信息的取值用于指示立即生效，则终端设备可采用如图1所示的流程中的第7个步骤的处理方式，在此不再赘述；若Mode信息的取值用于指示延迟生效，终端设备从接收的进行格式转换后的QoS策略中获取与该GBR QoS流对应的QFI，建立该GBR QoS流与QFI的映射关系，但终端设备暂不进行QFI到无线资源的映射。After receiving the Mode information and the QoS policy after format conversion, the terminal device performs corresponding processing according to the value of the Mode information. For example, if the value of the Mode information is used to indicate that it takes effect immediately, the terminal device may adopt the processing method of the seventh step in the process shown in FIG. 1, which is not repeated here; if the value of the Mode information is used Indicates that the delay takes effect. The terminal device obtains the QFI corresponding to the GBR QoS flow from the received QoS policy after format conversion, and establishes the mapping relationship between the GBR QoS flow and QFI. However, the terminal device does not perform QFI to wireless resource mapping for the time being. .

需要说明的是，步骤308-步骤311的执行顺序可以是依次执行步骤308-步骤311，也可以先分别执行步骤308和步骤310，然后在分别执行步骤309和步骤311，也可以同时执行步骤308和步骤310，然后同时执行步骤309和步骤311，在本申请实施例中，对步骤308-步骤311的执行顺序不作限制。It should be noted that the execution order of steps 308 to 311 may be to execute steps 308 to 311 in sequence, or to perform steps 308 and 310 respectively first, and then perform steps 309 and 311 respectively, or perform step 308 simultaneously. And step 310, and then execute step 309 and step 311 simultaneously. In the embodiment of the present application, the execution order of steps 308 to 311 is not limited.

当执行完成上述步骤后，(R)AN网元和终端设备均获取了与该GBR QoS流对应的QoS策略，但未对该GBR QoS流建立无线承载。在本申请实施例中，(R)AN网元需要接收到用于指示与该GBR QoS流对应的QoS策略已生效的第一信息后，才根据该QoS策略为该GBR QoS流建立无线承载。在这种情况下，QoS策略和第一信息是不同的信息，而且是分开获取的。After performing the above steps, both the (R) AN network element and the terminal device have obtained the QoS policy corresponding to the GBR QoS flow, but no radio bearer has been established for the GBR QoS flow. In the embodiment of the present application, the (R) AN network element needs to receive the first information indicating that the QoS policy corresponding to the GBR QoS flow has taken effect before establishing a radio bearer for the GBR QoS flow according to the QoS policy. In this case, the QoS policy and the first information are different information and are obtained separately.

在本申请实施例中，第一信息为与该GBR QoS流对应的业务数据。第一信息的获取方式可以包括但不限于如下两种，下面通过步骤312和步骤313分别对这两种不同的获取方式进行说明。In the embodiment of the present application, the first information is service data corresponding to the GBR QoS flow. The first information acquisition methods may include, but are not limited to, the following two methods. The two different acquisition methods are described below through steps 312 and 313, respectively.

第一种获取方式：The first way of obtaining:

步骤312、终端设备向(R)AN网元发送与该GBR QoS流对应的业务数据。Step 312: The terminal device sends service data corresponding to the GBR QoS flow to the (R) AN network element.

具体来讲，每个PDU会话中，(R)AN网元与终端设备之间有一个缺省的无线承载，当终端设备确定需要进行与该GBR QoS流对应的业务数据，则终端设备通过该缺省的无线承载，将该业务数据发送给(R)AN网元，在给(R)AN网元的业务数据中携带该GBR QoS流的QFI以及Mode信息。Specifically, in each PDU session, there is a default radio bearer between the (R) AN network element and the terminal device. When the terminal device determines that service data corresponding to the GBR QoS flow is required, the terminal device passes the The default radio bearer sends the service data to the (R) AN network element, and the service data to the (R) AN network element carries the QFI and Mode information of the GBR QoS flow.

在执行完步骤312之后，便执行步骤314。After step 312 is performed, step 314 is performed.

第二种获取方式：The second way of obtaining:

步骤313、UPF网元向(R)AN网元发送与该GBR QoS流对应的业务数据。Step 313: The UPF network element sends service data corresponding to the GBR QoS flow to the (R) AN network element.

具体来讲，若该GBR QoS流对应的下行业务数据发生，UPF网元可以识别该业务数据，并为该业务数据标识与该GBR QoS流对应的QFI，并将该业务数据发送给(R)AN网元，在发送给(R)AN网元的业务数据中携带该QFI以及与该GBR QoS流对应的Mode信息。Specifically, if the downlink service data corresponding to the GBR QoS flow occurs, the UPF network element can identify the service data, identify the QFI corresponding to the GBR QoS flow for the service data, and send the service data to (R) The AN network element carries the QFI and Mode information corresponding to the GBR QoS flow in the service data sent to the (R) AN network element.

在执行完步骤313之后，便执行步骤314。After step 313 is performed, step 314 is performed.

需要说明的是，步骤312和步骤313可选择一种执行，即若执行步骤312则不执行步骤313，或者执行步骤313则不执行步骤312。在具体实现过程中，可根据该GBR QoS流的业务数据的发送方来选择执行步骤312或者步骤313，例如，该GBR QoS流的业务数据的发送方为终端设备，则选择执行步骤312，该GBR QoS流的业务数据的发送方为DN网元，则选择执行步骤313，具体如何选择执行步骤312或者步骤313，在本申请实施例中不作限制。It should be noted that, step 312 and step 313 can be selected to be performed, that is, if step 312 is performed, step 313 is not performed, or step 313 is not performed. In the specific implementation process, step 312 or step 313 may be selected and executed according to the sender of the service data of the GBR QoS flow. For example, if the sender of the service data of the GBR QoS flow is a terminal device, then step 312 is selected to be performed. The sender of the service data of the GBR QoS flow is a DN network element, and then step 313 is selected and executed. How to select step 312 or step 313 is not specifically limited in the embodiment of the present application.

步骤314、(R)AN网元和终端设备建立与该GBR QoS流对应的无线承载。Step 314: The (R) AN network element and the terminal device establish a radio bearer corresponding to the GBR QoS flow.

当(R)AN网元接收终端设备发送的携带有与该GBR QoS流的QFI和Mode信息的业务数据或UPF网元发送的携带有与该GBR QoS流的QFI和Mode信息的业务数据后，(R)AN网元和终端设备则根据与该GBR QoS流对应的QoS策略，为该GBR QoS流建立相应的无线承载，从而为该业务数据流提供相应的QoS保障，具体建立无线承载的过程与现有技术中的QoS相关流程相同，在此不再赘述。After the (R) AN network element receives service data sent by the terminal device and carrying QFI and Mode information related to the GBR QoS flow or service data sent by UPF network elements and carries QFI and Mode information related to the GBR QoS flow, The (R) AN network element and terminal device establish a corresponding radio bearer for the GBR QoS flow according to the QoS policy corresponding to the GBR QoS flow, so as to provide corresponding QoS guarantee for the service data flow. The specific process of establishing a wireless bearer It is the same as the QoS related process in the prior art, and is not repeated here.

需要说明的是，若(R)AN网元无法为该GBR QoS流建立无线承载，例如，(R)AN网元根据准入控制原则确定无法为该GBR QoS流建立无线承载，或者(R)AN网元中不存在与该QoS策略匹配的资源，则(R)AN网元向SMF网元上报资源分配失败结果。在本申请实施例中，以(R)AN网元成功为该GBR QoS流建立无线承载为例进行说明。It should be noted that if the (R) AN network element cannot establish a radio bearer for the GBR QoS flow, for example, the (R) AN network element determines that it cannot establish a radio bearer for the GBR QoS flow according to the admission control principle, or (R) If there are no resources in the AN network element that match the QoS policy, the (R) AN network element reports the resource allocation failure result to the SMF network element. In the embodiment of the present application, the (R) AN network element successfully establishes a radio bearer for the GBR QoS flow as an example for description.

通过在建立无线承载的过程中引入QoS策略的生效模式，例如，Mode信息，这样，用于建立无线承载的相关网元可根据业务数据发生的时机为该GBR QoS流提供QoS保障，从而避免由于不可预期业务数据的发生时机，造成的(R)AN网元为该GBR QoS流分配的无线资源空置而造成的资源浪费的问题，可以提高资源的利用率。By introducing the effective mode of the QoS policy during the process of establishing the radio bearer, for example, Mode information, the relevant network elements used to establish the radio bearer can provide QoS guarantee for the GBR QoS flow according to the timing of service data occurrence, thereby avoiding The occurrence of unexpected service data causes resource waste caused by the vacancy of radio resources allocated by the (R) AN network element for the GBR QoS flow, which can improve resource utilization.

步骤315、(R)AN网元监测该GBR QoS流的业务数据传输情况，确定在预设时长内未通过该无线承载传输业务数据，则释放该无线承载对应的资源。Step 315: The (R) AN network element monitors the service data transmission of the GBR QoS flow, determines that service data is not transmitted through the radio bearer within a preset period of time, and then releases the resources corresponding to the radio bearer.

当(R)AN网元为该GBR QoS流建立无线承载后，还需要检测该无线承载内的业务数据传输情况，若在预设时长内无业务数据传输，该预设时长可以为10s或者30s等，则(R)AN网元进行QFI老化资源回收，发起释放与该GBR QoS流的资源的流程。After the (R) AN network element establishes a radio bearer for the GBR QoS flow, it is also necessary to detect the service data transmission in the radio bearer. If there is no service data transmission within a preset time period, the preset time period can be 10s or 30s. If so, the (R) AN network element recovers QFI aging resources and initiates a process of releasing resources related to the GBR QoS flow.

在本申请实施例中，(R)AN网元可以根据业务数据的传输情况触发对资源的释放流程，这样，在不需要使用该资源进行业务数据传输时，则主动释放该资源，从而可以进一步提高资源的利用率。In the embodiment of the present application, the (R) AN network element may trigger the release process of the resource according to the transmission of service data. In this way, when the resource is not required for service data transmission, the resource is actively released, which can further Improve resource utilization.

需要说明的是，步骤315为可选步骤，即，不是必须执行的。It should be noted that step 315 is an optional step, that is, it does not have to be performed.

另外，需要说明的是，QoS流的建立过程包括核心网侧隧道(tunnel)的建立过程和无线承载的建立过程，在本申请实施例中仅以无线承载的建立过程为例进行描述，对于核心网侧的tunnel的建立过程在本申请实施例中不作限制。In addition, it should be noted that the establishment process of the QoS flow includes the establishment process of the core network side tunnel (tunnel) and the establishment process of the radio bearer. In the embodiment of the present application, only the establishment process of the radio bearer is described as an example. The establishment process of the network-side tunnel is not limited in the embodiments of the present application.

在上述实施例中，无线承载的建立过程是由PDU会话建立时UDR中的静态签约数据中的QoS策略触发的，在具体实施过程中，无线承载的建立也可以是由AF网元或者第三方触发的，例如，在VoLTE场景中，AF为特定的业务流请求QoS保障，或者在第三方QoS加速场景中，OTT为特定业务流请求QoS提升等，下面将对这种情况进行介绍。In the above embodiment, the establishment process of the radio bearer is triggered by the QoS policy in the static subscription data in the UDR when the PDU session is established. In the specific implementation process, the establishment of the radio bearer may also be performed by the AF network element or a third party. Triggered, for example, in the VoLTE scenario, AF requests QoS guarantee for a specific service flow, or in a third-party QoS acceleration scenario, OTT requests QoS promotion for a specific service flow, etc. This situation will be described below.

请参考图4，为本申请另一实施例提供的一种无线承载建立方法的流程图，该流程图的描述如下：Please refer to FIG. 4, which is a flowchart of a method for establishing a radio bearer according to another embodiment of the present application. The description of the flowchart is as follows:

步骤401、AF网元向PCF网元发送对业务流的QoS保障请求，PCF网元接收该QoS保障请求。在执行步骤401之后，便可以执行步骤403。Step 401: The AF network element sends a QoS guarantee request for the service flow to the PCF network element, and the PCF network element receives the QoS guarantee request. After step 401 is performed, step 403 may be performed.

步骤402、NEF网元向PCF网元发送对业务流的QoS提升请求，PCF网元接收该QoS提升请求。在本申请实施例中，由于与AF网元或NEF网元交互的业务流有多个，为方便描述，后文将以其中一个业务流且该其中一个业务流为GBR QoS流为例进行说明。在执行步骤402之后，便也可以执行步骤403。Step 402: The NEF network element sends a QoS improvement request for the service flow to the PCF network element, and the PCF network element receives the QoS improvement request. In the embodiment of the present application, since there are multiple service flows interacting with the AF network element or NEF network element, for the convenience of description, the following description will use one of the service flows and the one of the service flows is a GBR QoS flow as an example. . After step 402 is performed, step 403 may also be performed.

需要说明的是，步骤401与步骤402可以选择其中一个步骤执行，即只执行步骤401不执行步骤402，或者只执行步骤402不执行步骤401，在图4中以执行步骤401为例进行说明。It should be noted that step 401 and step 402 may be selected from one of the steps, that is, only step 401 is not performed, or step 402 is performed only, and step 401 is not performed. Step 4 is taken as an example for illustration in FIG. 4.

另外，需要说明的是，该QoS保障请求或该QoS提升请求中还可以携带有QoS策略的生效模式，该生效模式与步骤304中相同，在此不再赘述，在本申请实施例中，以该生效模式标记为Mode信息为例进行说明。由于AF网元向PCF网元发送QoS保障请求或NEF网元在向PCF网元发送QoS提升请求时，已经明确与该GBR QoS流对应的业务数据即将发生，因此，该QoS保障请求或QoS提升请求中携带的Mode信息的取值指示立即生效。当然，该QoS保障请求或QoS提升请求中也可以不携带Mode信息，在此不作限制。In addition, it should be noted that the QoS guarantee request or the QoS promotion request may also carry an effective mode of a QoS policy. The effective mode is the same as that in step 304, and will not be repeated here. In the embodiment of the present application, the The effective mode is marked as Mode information as an example for illustration. Since the AF network element sends a QoS guarantee request to the PCF network element or when the NEF network element sends a QoS improvement request to the PCF network element, it is clear that the service data corresponding to the GBR QoS flow is about to occur. Therefore, the QoS guarantee request or QoS improvement The value of the Mode information carried in the request is effective immediately. Of course, the QoS guarantee request or QoS promotion request may not carry Mode information, which is not limited herein.

需要说明的是，该QoS保障请求或QoS提升请求中未携带Mode信息，PCF网元在生成与该GBR QoS流对应的QoS策略后，还需为该QoS策略设置Mode信息的取值。在这种情况下，PCF网元将Mode信息的取值指示立即生效。It should be noted that Mode information is not carried in the QoS guarantee request or QoS promotion request. After generating the QoS policy corresponding to the GBR QoS flow, the PCF network element needs to set the value of Mode information for the QoS policy. In this case, the PCF network element takes the value indication of the Mode information into effect immediately.

另外，需要说明的是，Mode信息与QoS策略的关系与步骤304中相同，在此不再赘述。In addition, it should be noted that the relationship between the Mode information and the QoS policy is the same as that in step 304, and details are not described herein again.

步骤404、PCF网元向SMF网元发送该QoS策略和第一信息，SMF网元接受该QoS策略和第一信息。Step 404: The PCF network element sends the QoS policy and the first information to the SMF network element, and the SMF network element accepts the QoS policy and the first information.

在本申请实施例中，第一信息用于指示该QoS策略即将生效。由于PCF网元确定该Mode信息的取值指示立即生效，因此，该Mode信息即为该第一信息，在下面的介绍中，将以Mode信息为例进行说明。In the embodiment of the present application, the first information is used to indicate that the QoS policy is about to take effect. Because the PCF network element determines that the value indication of the Mode information is effective immediately, the Mode information is the first information. In the following description, the Mode information will be used as an example for description.

步骤406、UPF网元根据Mode信息进行处理。Step 406: The UPF network element performs processing according to the Mode information.

UPF网元从SMF网元接收Mode信息后，可根据Mode信息的取值进行相应的处理。在本申请实施例中，Mode信息的取值用于指示立即生效，则UPF网元可采用如图1所示的流程中的第3个步骤的处理方式，在此不再赘述。After the UPF network element receives the Mode information from the SMF network element, it can perform corresponding processing according to the value of the Mode information. In the embodiment of the present application, the value of the Mode information is used to indicate immediate effect. The UPF network element may adopt the processing method of the third step in the process shown in FIG. 1, and details are not described herein again.

步骤407、SMF网元将该QoS策略和Mode信息发送给(R)AN网元，(R)AN网元接收该QoS策略和Mode信息。Step 407: The SMF network element sends the QoS policy and Mode information to the (R) AN network element, and the (R) AN network element receives the QoS policy and Mode information.

步骤404-步骤407与步骤305-步骤308相同，在此不再赘述。Steps 404 to 407 are the same as steps 305 to 308, and details are not described herein again.

步骤408、(R)AN网元根据Mode信息进行处理。Step 408: The (R) AN network element performs processing according to the Mode information.

具体来讲，(R)AN网元接收Mode信息和该QoS策略后，根据该Mode信息的取值进行相应的处理。具体Mode信息的取值与(R)AN网元的操作之间的对应关系与步骤309中相同，在此不再赘述。Specifically, after receiving the Mode information and the QoS policy, the (R) AN network element performs corresponding processing according to the value of the Mode information. The corresponding relationship between the value of the specific Mode information and the operation of the (R) AN network element is the same as that in step 309, and details are not described herein again.

在本申请实施例中，以Mode信息的取值指示立即生效为例，因此，(R)AN网元采用如图1所示的流程中的第5个步骤的处理方式，为该GBR QoS流分配资源，以及建立与该GBR QoS流对应的无线承载，在此不再赘述。In the embodiment of the present application, the value indication of the Mode information takes effect immediately as an example. Therefore, the (R) AN network element adopts the processing method of the fifth step in the process shown in FIG. 1 to provide the GBR QoS flow. Allocating resources and establishing a radio bearer corresponding to the GBR QoS flow are not repeated here.

步骤409、SMF网元将该QoS策略和Mode信息发送给终端设备，终端设备接收该QoS策略和Mode信息。Step 409: The SMF network element sends the QoS policy and Mode information to the terminal device, and the terminal device receives the QoS policy and Mode information.

步骤409与步骤310相同，在此不再赘述。Step 409 is the same as step 310, and details are not described herein again.

步骤410、终端设备根据Mode信息进行处理。Step 410: The terminal device performs processing according to the Mode information.

具体来讲，终端设备接收Mode信息和该QoS策略后，根据该Mode信息的取值进行不同的处理。具体Mode信息的取值与终端设备的操作之间的对应关系与步骤311中相同，在此不再赘述。Specifically, after receiving the Mode information and the QoS policy, the terminal device performs different processing according to the value of the Mode information. The corresponding relationship between the value of the specific Mode information and the operation of the terminal device is the same as that in step 311, and details are not described herein again.

在本申请实施例中，由于Mode信息的取值指示立即生效，则终端设备采用如图1所示的流程中的第7个步骤的处理方式，实现GBR QoS流到QFI的映射，以及QFI到无线资源的映射，从而为GBR QoS流建立无线承载，在此不再赘述。In the embodiment of the present application, since the value indication of the Mode information takes effect immediately, the terminal device adopts the processing method of the seventh step in the process shown in FIG. 1 to implement the mapping of GBR QoS flow to QFI, and QFI to The mapping of wireless resources, so as to establish a wireless bearer for the GBR QoS flow, will not be repeated here.

在完成上述步骤后，(R)AN网元与终端设备则为GBR QoS流建立了无线承载，从而为该GBR QoS流对应的业务数据提供QoS保障。通过在建立无线承载的过程中引入QoS策略的生效模式，例如，Mode信息，这样，用于建立无线承载的相关网元可在QoS策略的生效模式指示该QoS策略为立即生效模式时，立即为该GBR QoS流建立无线承载，并为该GBR QoS流提供QoS保障，从而避免由于不可预期业务数据的发生时机，造成的(R)AN网元为该GBR QoS流分配的无线资源空置而造成的资源浪费的问题，可以提高资源的利用率。After completing the above steps, the (R) AN network element and the terminal device establish a wireless bearer for the GBR QoS flow, thereby providing QoS guarantee for the service data corresponding to the GBR QoS flow. By introducing the effective mode of the QoS policy in the process of establishing the wireless bearer, for example, Mode information, the relevant network elements used to establish the wireless bearer can immediately indicate that the QoS policy is in the immediate effective mode when the effective mode of the QoS policy indicates The GBR QoS flow establishes a wireless bearer and provides QoS guarantee for the GBR QoS flow, thereby avoiding the radio resource allocated by the (R) AN network element for the GBR QoS flow from being vacant due to the occurrence of unexpected service data. The problem of waste of resources can improve the utilization of resources.

当AF网元或者第三方无需再使用该GBR QoS流时，则向(R)AN网元发送控制指令，以释放该无线承载。When the AF network element or a third party does not need to use the GBR QoS flow any more, it sends a control instruction to the (R) AN network element to release the radio bearer.

在上述实施例中，无线承载的建立过程是由(R)AN网元根据QoS策略的生效模式或根据是否有业务数据发生，来判断是否需要立即或延迟建立，且(R)AN网元可以支持对业务数据的传输情况进行监测，并根据业务数据的传输情况确定是否进行资源回收，而对于SMF网元或者UPF网元等则仅需要支持对QoS策略的生效模式进行转发的功能，对SMF网元以及UPF网元的改动较小。In the above embodiment, the establishment process of the radio bearer is determined by the (R) AN network element according to the effective mode of the QoS policy or according to whether service data occurs, and whether the establishment is required immediately or delayed, and the (R) AN network element can Supports monitoring the transmission of business data and determining whether to recover resources based on the transmission of business data. For SMF network elements or UPF network elements, it only needs to support the function of forwarding the effective mode of the QoS policy, and SMF The network elements and UPF network elements have minor changes.

鉴于此，本申请另一实施例提供一种以SMF网元为主来判断是否需要立即或延迟建立与业务流对应的无线承载的方法，请参考图5，为该方法的流程图，该流程图的描述如下：In view of this, another embodiment of the present application provides a method based on SMF network elements to determine whether a radio bearer corresponding to a service flow needs to be established immediately or delayed. Please refer to FIG. 5 for a flowchart of the method. The description of the diagram is as follows:

步骤501、终端设备向SMF网元发送PDU会话建立请求，SMF网元接收该PDU会话建立请求。Step 501: The terminal device sends a PDU session establishment request to the SMF network element, and the SMF network element receives the PDU session establishment request.

步骤501与步骤301相同，在此不再赘述。在下面的描述中，将以业务流为PDU会话中的GBR QoS流、终端设备为与SMF网元交互的其中一个终端设备为例进行描述。Step 501 is the same as step 301, and details are not described herein again. In the following description, the service flow is taken as an example of the GBR QoS flow in the PDU session, and the terminal device is one of the terminal devices that interacts with the SMF network element.

步骤502、SMF网元向PCF网元发送与该PDU会话对应的QoS策略请求，PCF网元接收该QoS策略请求。Step 502: The SMF network element sends a QoS policy request corresponding to the PDU session to the PCF network element, and the PCF network element receives the QoS policy request.

步骤503、PCF网元从UDR网元获取终端设备的静态签约数据。Step 503: The PCF network element obtains the static contract data of the terminal device from the UDR network element.

步骤504、PCF网元根据静态签约数据获取相应的QoS策略，以及确定该QoS策略的生效模式。Step 504: The PCF network element obtains a corresponding QoS policy according to the static contract data, and determines an effective mode of the QoS policy.

需要说明的是，该QoS策略的生效模式与步骤304中相同，例如，可以为Mode信息，在本申请实施例中，以该Mode信息的取值指示延迟生效为例进行说明。It should be noted that the effective mode of the QoS policy is the same as that in step 304. For example, the effective mode of the QoS policy may be Mode information. In the embodiment of the present application, the value of the Mode information is used to indicate that the delay is valid for example.

需要说明的是，步骤501-步骤504为可选步骤，即不是必须要执行的。It should be noted that steps 501 to 504 are optional steps, that is, they do not have to be performed.

步骤505、PCF网元向SMF网元发送该QoS策略和第二信息，SMF网元接收该QoS策略和该第二信息。Step 505: The PCF network element sends the QoS policy and the second information to the SMF network element, and the SMF network element receives the QoS policy and the second information.

在本申请实施例中，第二信息用于指示延迟为GBR QoS流建立无线承载。由于PCF网元确定该Mode信息的取值指示延迟生效，因此，该Mode信息即为该第二信息，在下面的介绍中，将以Mode信息为例进行说明。In the embodiment of the present application, the second information is used to indicate a delay in establishing a radio bearer for the GBR QoS flow. Because the PCF network element determines that the value of the Mode information indicates that the delay is effective, the Mode information is the second information. In the following description, the Mode information will be used as an example for description.

步骤502-步骤505与步骤302-步骤305相同，在此不再赘述。Steps 502 to 505 are the same as steps 302 to 305, and details are not described herein again.

步骤506、SMF网元根据该Mode信息进行处理。Step 506: The SMF network element performs processing according to the Mode information.

具体来讲，SMF网元从PCF网元接收Mode信息后，根据该Mode信息的取值进行相应的处理。例如，若SMF网元确定该Mode信息的取值指示立即生效，则SMF网元将该QoS策略分别发送给UPF网元、(R)AN网元以及终端设备。若SMF网元确定该Mode信息的取值指示延迟生效，则SMF网元将该QoS策略和该Mode等信息发送该UPF网元，并使能UPF网元的业务检测及上报功能，且SMF网元缓存向(R)AN网元以及终端设备发送的QoS策略，即暂时不向(R)AN网元以及终端设备发送该QoS策略。Specifically, after receiving the Mode information from the PCF network element, the SMF network element performs corresponding processing according to the value of the Mode information. For example, if the SMF network element determines that the value indication of the Mode information is effective immediately, the SMF network element sends the QoS policy to the UPF network element, the (R) AN network element, and the terminal device, respectively. If the SMF network element determines that the value of the Mode information indicates that the delay is effective, the SMF network element sends the QoS policy and the Mode and other information to the UPF network element, and enables the service detection and reporting function of the UPF network element, and the SMF network The meta buffer buffers the QoS policy sent to the (R) AN network element and the terminal device, that is, the QoS policy is not temporarily sent to the (R) AN network element and the terminal device.

需要说明的是，SMF网元使能UPF网元的业务检测及上报功能，可以通过现有技术中的使用量上报(usage reporting)功能完成，usage reporting功能可用于检测业务数据的开始和结束，后续当UPF网元检测到该业务数据的开始以及该业务数据结束后，则向SMF网元上报，在此不再赘述。It should be noted that the SMF network element enables the service detection and reporting function of the UPF network element, which can be completed by the usage report function in the prior art. The usage report function can be used to detect the start and end of service data. Afterwards, when the UPF network element detects the start of the service data and the service data ends, it reports to the SMF network element, which will not be repeated here.

在本申请实施例中，以该Mode信息的取值指示延迟生效，即指示延迟为该GBR QoS流建立无线承载为例，则SMF网元仅向UPF网元发送该QoS策略和该Mode信息，并使能UPF网元的业务检测及上报功能。In the embodiment of the present application, taking the value of the Mode information to indicate that the delay is effective, that is, instructing the delay to establish a radio bearer for the GBR QoS flow as an example, the SMF network element sends the QoS policy and the Mode information to the UPF network element only. And enable the service detection and reporting function of the UPF network element.

SMF网元向UPF网元发送该QoS策略的方法与步骤306中相同，在此不再赘述。The method for the SMF network element to send the QoS policy to the UPF network element is the same as that in step 306, and details are not described herein again.

步骤507、UPF网元根据从SMF网元接收的信息进行处理。Step 507: The UPF network element performs processing according to the information received from the SMF network element.

具体来讲，步骤507可以但不限于包含如下两种情况：Specifically, step 507 may include, but is not limited to, the following two cases:

第一种情况，SMF网元确定该Mode信息的取值指示延迟生效，则向UPF网元发送该QoS策略以及该Mode信息，SMF网元确定该Mode信息的取值指示立即生效，则向UPF网元发送该QoS策略但是不发送该Mode信息，在这种情况下，UPF网元根据是否接收到该Mode信息来进行相应的处理，例如，若UPF网元判断未从SMF网元接收该Mode信息，则UPF网元则采用如图1所示的流程中的第3个步骤的处理方式，实施相应的计费和带宽控制等控制策略，若UPF网元判断从SMF网元接收到该Mode信息，则UPF网元实现业务识别以及该GBR QoS流到该QoS策略中携带的QFI的映射，实施相应的控制策略，并开启业务的检测及上报功能。In the first case, when the SMF network element determines that the value of the Mode information indicates that the delay is effective, it sends the QoS policy and the Mode information to the UPF network element. When the SMF network element determines that the value of the Mode information takes effect immediately, it sends the UPF to the UPF. The network element sends the QoS policy but does not send the Mode information. In this case, the UPF network element performs corresponding processing according to whether the Mode information is received. For example, if the UPF network element determines that the Mode is not received from the SMF network element. Information, the UPF network element adopts the processing method of the third step in the process shown in Figure 1, and implements the corresponding charging and bandwidth control control strategies. If the UPF network element determines that it has received the Mode from the SMF network element Information, the UPF network element implements service identification and mapping of the GBR QoS flow to the QFI carried in the QoS policy, implements the corresponding control strategy, and enables the service detection and reporting functions.

第二种情况，无论该Mode信息的取值指示何值，SMF网元都会向UPF网元发送该QoS策略以及该Mode信息，在这种情况下，UPF网元根据接收到的该Mode信息的取值来进行相应的处理，例如，若UPF网元判断该Mode信息的取值指示立即生效，则UPF网元则采用如图1所述的流程中的第3个步骤的处理方式，实施相应的计费和带宽控制等控制策略；若UPF网元判断该Mode信息的取值指示延迟生效，则UPF网元实现业务识别及该GBR QoS流到该QoS策略中携带的QFI的映射，实施相应的控制策略，并开启业务的检测及上报功能。In the second case, no matter what the value of the Mode information indicates, the SMF network element sends the QoS policy and the Mode information to the UPF network element. In this case, the UPF network element receives the Mode information according to the received Mode information. Take the value for corresponding processing. For example, if the UPF network element judges that the value indication of the Mode information is effective immediately, the UPF network element adopts the processing method of the third step in the process shown in FIG. 1 to implement the corresponding process. Control strategies such as charging and bandwidth control; if the UPF network element judges that the value of the Mode information indicates that the delay is effective, the UPF network element implements service identification and mapping of the GBR QoS flow to the QFI carried in the QoS policy, and implements the corresponding Control strategy, and enable business detection and reporting functions.

在下面的介绍中，以第一种情况为例进行说明。在本申请实施例中，该Mode信息的取值指示延迟生效，在这种情况下，UPF网元判断从SMF网元接收到该Mode信息，则UPF网元实现业务识别及该GBR QoS流到该QoS策略中携带的QFI的映射，实施相应的控制策略，并开启业务的检测及上报功能。In the following introduction, the first case is taken as an example. In the embodiment of the present application, the value of the Mode information indicates that the delay takes effect. In this case, the UPF network element determines that the Mode information is received from the SMF network element, and the UPF network element implements service identification and the GBR QoS flow arrives. The QFI mapping carried in the QoS policy implements the corresponding control strategy and enables the service detection and reporting functions.

步骤508、UPF网元在检测到该GBR QoS流的业务数据时，向SMF网元发送第一信息，SMF网元接收该第一信息。Step 508: When the UPF network element detects the service data of the GBR QoS flow, it sends the first information to the SMF network element, and the SMF network element receives the first information.

当SMF网元接收由UPF网元发送的第一信息后，则确定该GBR QoS流的QoS策略已生效，则将由PCF网元获取的该QoS策略发送给(R)AN网元，SMF网元向(R)AN网元发送该QoS策略的过程与步骤308相同，在此不再赘述。需要说明的是，在这种情况下，SMF网元只向(R)AN网元发送该QoS策略，而不发送Mode信息。When the SMF network element receives the first information sent by the UPF network element, it determines that the QoS policy of the GBR QoS flow has taken effect, and then sends the QoS policy obtained by the PCF network element to the (R) AN network element, and the SMF network element The process of sending the QoS policy to the (R) AN network element is the same as step 308, and is not repeated here. It should be noted that, in this case, the SMF network element only sends the QoS policy to the (R) AN network element, and does not send Mode information.

步骤510、(R)AN网元和终端设备为该GBR QoS流建立无线承载。Step 510: The (R) AN network element and the terminal device establish a radio bearer for the GBR QoS flow.

需要说明的是，在这种情况下，SMF网元只向终端设备发送该QoS策略，而不发送Mode信息。It should be noted that, in this case, the SMF network element only sends the QoS policy to the terminal device, and does not send Mode information.

步骤512、终端设备实现该GBR QoS流到QFI的映射，以及QFI到(R)AN网元分配的资源的映射。Step 512: The terminal device implements mapping of the GBR QoS flow to QFI, and mapping of QFI to resources allocated by the (R) AN network element.

步骤512与如图1所示的流程中的第7个步骤的处理方式相同，在此不再赘述。Step 512 is the same as the seventh step in the process shown in FIG. 1 and will not be repeated here.

需要说明的是，步骤509-步骤512的执行顺序可以是依次执行步骤509-步骤512，也可以先分别执行步骤509和步骤511，然后在分别执行步骤510和步骤512，也可以同时执行步骤509和步骤511，然后同时执行步骤510和步骤512，在本申请实施例中，对步骤509-步骤512的执行顺序不作限制。It should be noted that the execution order of steps 509 to 512 may be to execute steps 509 to 512 in sequence, or to perform steps 509 and 511 respectively, and then perform steps 510 and 512 respectively, or perform step 509 at the same time. And step 511, and then execute step 510 and step 512 simultaneously. In the embodiment of the present application, the execution order of steps 509 to 512 is not limited.

通过在建立无线承载的过程中引入QoS策略的生效模式，例如，Mode信息，这样，SMF网元可以根据该GBR QoS流的业务数据发生的时机，向用于建立无线承载的网元，例如(R)AN网元、终端设备等发送与该GBR QoS流对应的QoS策略，为该GBR QoS流提供QoS保障，从而避免由于不可预期业务数据的发生时机，造成的(R)AN网元为该GBR QoS流分配的无线资源空置而造成的资源浪费的问题，可以提高资源的利用率。By introducing the effective mode of the QoS policy, for example, Mode information, in the process of establishing the radio bearer, the SMF network element can provide the network element used to establish the radio bearer to the network element used to establish the radio bearer according to the timing of the service data of the GBR QoS flow, such as ( R) AN network element, terminal equipment, etc. send the QoS policy corresponding to the GBR QoS flow to provide QoS guarantee for the GBR QoS flow, thereby avoiding the occurrence of (R) AN network element due to the unexpected timing of business data. The problem of resource waste caused by vacant radio resources allocated by GBR QoS flow can improve resource utilization.

步骤513、UPF网元监测该GBR QoS流的业务数据传输情况，确定在预设时长内未通过该无线承载传输业务数据，向SMF网元发送第三信息，SMF网元接收该第三信息。Step 513: The UPF network element monitors the service data transmission of the GBR QoS flow, determines that the service data is not transmitted through the radio bearer within a preset time, sends third information to the SMF network element, and the SMF network element receives the third information.

在本申请实施例中，该第三信息用于指示在该预设时长内未检测到该GBR QoS流的业务数据。该第三信息可以通过usage reporting功能中的相关信令实现，在此不再赘述。In the embodiment of the present application, the third information is used to indicate that service data of the GBR QoS flow is not detected within the preset time period. The third information may be implemented through related signaling in the usage reporting function, and details are not described herein again.

当UPF网元向SMF网元上报该第一信息后，还需要检测该无线承载内的业务数据传输情况，若在预设时长内无业务数据传输，该预设时长可以为10s或者30s等，则UPF网元向SMF网元发送该第三信息。After the UPF network element reports the first information to the SMF network element, it is also necessary to detect the transmission of service data in the radio bearer. If there is no service data transmission within a preset period, the preset period may be 10s or 30s, etc. The UPF network element sends the third information to the SMF network element.

步骤514、SMF网元向(R)AN网元发送第四信息，(R)AN网元接收该第四信息。在本申请实施例中，该第四信息用于指示(R)AN网元释放该无线承载。Step 514: The SMF network element sends the fourth information to the (R) AN network element, and the (R) AN network element receives the fourth information. In the embodiment of the present application, the fourth information is used to instruct the (R) AN network element to release the radio bearer.

这样，SMF网元可以根据业务数据的传输情况触发(R)AN网元对资源的释放流程，从而在不需要使用该资源进行业务数据传输时，则主动释放该资源，可以进一步提高资源的利用率。In this way, the SMF network element can trigger the release process of the resource by the (R) AN network element according to the transmission of service data, so that when the resource is not required for service data transmission, it actively releases the resource, which can further improve the utilization of the resource. rate.

需要说明的是，步骤513-515不是必须执行的，即为可选步骤。It should be noted that steps 513-515 are not required to be performed, they are optional steps.

在上述实施例中，无线承载的建立过程是由PDU会话建立时UDR中的静态签约数据中的QoS策略触发的，在具体实施过程中，无线承载的建立也可以是由AF网元或者第三方触发的，例如，在VoLTE场景中，AF为特定的业务流请求QoS保障，或者在第三方QoS加速场景中，OTT为特定业务流请求QoS提升等，下面将对这种情况进行介绍。In the above embodiment, the establishment process of the radio bearer is triggered by the QoS policy in the static subscription data in the UDR when the PDU session is established. In the specific implementation process, the establishment of the radio bearer may also be performed by the AF network element or a third party Triggered, for example, in the VoLTE scenario, AF requests QoS guarantee for a specific service flow, or in a third-party QoS acceleration scenario, OTT requests QoS promotion for a specific service flow, etc. This situation will be described below.

请参考图6，为本申请另一实施例提供的一种无线承载建立方法的流程图，该流程图的描述如下：Please refer to FIG. 6, which is a flowchart of a method for establishing a radio bearer according to another embodiment of the present application. The description of the flowchart is as follows:

步骤601、AF网元向PCF网元发送对业务流的QoS保障请求，PCF网元接收该QoS保障请求。在执行步骤601之后，便可以执行步骤603。Step 601: The AF network element sends a QoS guarantee request for the service flow to the PCF network element, and the PCF network element receives the QoS guarantee request. After step 601 is performed, step 603 may be performed.

步骤602、NEF网元向PCF网元发送对业务流的QoS提升请求，PCF网元接收该QoS提升请求。在本申请实施例中，由于与AF网元或NEF网元交互的业务流有多个，为方便描述，后文将以其中一个业务流且该其中一个业务流为GBR QoS流为例进行说明。在执行步骤602之后，便可以执行步骤603。Step 602: The NEF network element sends a QoS improvement request for the service flow to the PCF network element, and the PCF network element receives the QoS improvement request. In the embodiment of the present application, since there are multiple service flows interacting with the AF network element or NEF network element, for the convenience of description, the following description will use one of the service flows and the one of the service flows is a GBR QoS flow as an example. . After step 602 is performed, step 603 may be performed.

需要说明的是，步骤601与步骤602可以选择其中一个步骤执行，即只执行步骤601不执行步骤602，或者只执行步骤602不执行步骤601，在图6中以执行步骤601为例进行说明。It should be noted that, step 601 and step 602 may be selected to be performed, that is, only step 601 is not performed, or step 602 is performed only, and step 601 is not performed. In FIG. 6, step 601 is taken as an example for description.

步骤603、PCF网元根据该QoS保障请求或该QoS提升请求，生成与GBR QoS流对应的QoS策略。Step 603: The PCF network element generates a QoS policy corresponding to the GBR QoS flow according to the QoS guarantee request or the QoS promotion request.

步骤604、PCF网元向SMF网元发送该QoS策略和第一信息，SMF网元接受该QoS策略和该第一信息。Step 604: The PCF network element sends the QoS policy and the first information to the SMF network element, and the SMF network element accepts the QoS policy and the first information.

在本申请实施例中，第一信息用于指示该QoS策略即将生效。由于PCF网元确定该Mode信息的取值指示立即生效，因此，该Mode信息即为该第一信息，在下面的介绍中，将以Mode 信息为例进行说明。In the embodiment of the present application, the first information is used to indicate that the QoS policy is about to take effect. Since the PCF network element determines that the value indication of the Mode information is effective immediately, the Mode information is the first information. In the following description, the Mode information will be used as an example for description.

步骤601-步骤604与步骤401-步骤404相同，在此不再赘述。步骤601-步骤603为可选步骤，即不是必须执行的。Steps 601 to 604 are the same as steps 401 to 404, and details are not described herein again. Steps 601 to 603 are optional steps, that is, they do not have to be performed.

步骤605、SMF网元根据该Mode信息进行处理。Step 605: The SMF network element performs processing according to the Mode information.

具体来讲，SMF网元从PCF网元接收Mode信息后，根据Mode信息的取值进行相应的的处理。具体Mode信息的取值与SMF网元的操作之间的对应关系与步骤506中相同，在此不再赘述。Specifically, after receiving the Mode information from the PCF network element, the SMF network element performs corresponding processing according to the value of the Mode information. The corresponding relationship between the value of the specific Mode information and the operation of the SMF network element is the same as that in step 506, and details are not described herein again.

在本申请实施例中，以该Mode信息的取值指示立即生效为例，则SMF网元确定将该QoS策略分别发送给UPF网元、(R)AN网元以及终端设备。In the embodiment of the present application, taking the value indication of the Mode information as effective immediately, the SMF network element determines to send the QoS policy to the UPF network element, the (R) AN network element, and the terminal device, respectively.

需要说明的是，步骤605包含SMF网元将该QoS策略发送给UPF网元的过程、将该QoS策略发送给(R)AN网元的过程以及将该QoS策略发送给终端设备的过程，分别与图1所示的流程中的第2个步骤、第4个步骤以及第6个步骤的处理方式相同，在此不再赘述。It should be noted that step 605 includes the process of the SMF network element sending the QoS policy to the UPF network element, the process of sending the QoS policy to the (R) AN network element, and the process of sending the QoS policy to the terminal device, respectively. The processing method is the same as that of the second step, the fourth step, and the sixth step in the flow shown in FIG. 1, and details are not described herein again.

步骤606、UPF网元根据从SMF网元接收的信息进行处理。Step 606: The UPF network element performs processing according to the information received from the SMF network element.

具体来讲，步骤606可以但不限于包含如下两种情况，这两种情况的介绍与步骤507中相同，在此不再赘述。Specifically, step 606 may include, but is not limited to, the following two cases. The introduction of these two cases is the same as that in step 507, and details are not described herein again.

在本申请实施例中，以第一种情况为例进行说明。由于Mode信息的取值指示立即生效，因此，SMF网元仅向UPF网元发送该QoS策略而不发送Mode信息，在这种情况下，UPF网元判断未从SMF网元接收该Mode信息，则UPF网元则采用如图1所示的流程中的第3个步骤的处理方式，实施相应的计费和带宽控制等控制策略。In the embodiment of the present application, the first case is taken as an example for description. Since the value indication of the Mode information takes effect immediately, the SMF network element only sends the QoS policy to the UPF network element without sending the Mode information. In this case, the UPF network element determines that the Mode information is not received from the SMF network element. Then, the UPF network element adopts the processing method of the third step in the flow shown in FIG. 1 to implement corresponding control policies such as charging and bandwidth control.

步骤607、(R)AN网元根据该QoS策略为该GBR QoS流建立无线承载。Step 607: The (R) AN network element establishes a radio bearer for the GBR QoS flow according to the QoS policy.

步骤608、终端设备根据该QoS策略实现该业务流到QFI的映射，以及QFI到无线资源的映射。Step 608: The terminal device implements mapping of the service flow to QFI and mapping of QFI to wireless resources according to the QoS policy.

步骤607与步骤510相同，步骤608与步骤512相同，在此不再赘述。Step 607 is the same as step 510, and step 608 is the same as step 512, and details are not described herein again.

在完成上述步骤后，(R)AN网元与终端设备则为该GBR QoS流建立了无线承载，从而为该GBR QoS流对应的业务数据提供QoS保障。After completing the above steps, the (R) AN network element and the terminal device establish a wireless bearer for the GBR QoS flow, thereby providing QoS guarantee for the service data corresponding to the GBR QoS flow.

通过在建立无线承载的过程中引入QoS策略的生效模式，例如，Mode信息，这样，SMF网元可在QoS策略的生效模式指示该QoS策略为立即生效模式时，向用于建立无线承载的网元，例如(R)AN网元、终端设备等发送与该GBR QoS流对应的QoS策略，为该业务流提供QoS保障，从而避免由于不可预期业务数据的发生时机，造成的(R)AN网元为该GBR QoS流分配的无线资源空置而造成的资源浪费的问题，可以提高资源的利用率。By introducing the effective mode of the QoS policy, for example, Mode information, in the process of establishing the wireless bearer, the SMF network element can indicate to the network for establishing the wireless bearer when the effective mode of the QoS policy indicates that the QoS policy is the immediate effective mode. (R) AN network element, terminal equipment, etc. send the QoS policy corresponding to the GBR QoS flow to provide QoS guarantee for the service flow, thereby avoiding the (R) AN network caused by the unexpected timing of business data. The problem of resource waste caused by the vacancy of the radio resources allocated for the GBR QoS flow can improve the resource utilization rate.

在图5-图6所示的实施例中，由SMF网元负责根据Mode信息的取值判断是否需要立即或者延迟为业务流建立无线承载，并使能UPF网元的业务检查和上报功能来判断业务数据发生时机，仅在业务数据发生时或该Mode信息的取值为立即生效时，向(R)AN网元以及终端设备发送QoS策略，从而使(R)AN网元以及终端设备根据该QoS策略为该业务流建立无线承载，为该业务流提供QoS保证，而(R)AN网元以及终端设备本身并不感知Mode信息，这样，可以降低(R)AN网元以及终端设备的运算复杂度。In the embodiment shown in Figs. 5 to 6, the SMF network element is responsible for determining whether to establish a wireless bearer for the service flow immediately or delayed according to the value of the Mode information, and to enable the service check and report function of the UPF network element to Determining the timing of service data occurrence, only when the service data occurs or when the value of the Mode information takes effect immediately, the QoS policy is sent to the (R) AN network element and the terminal device, so that the (R) AN network element and the terminal device are based on The QoS policy establishes a wireless bearer for the service flow and provides QoS guarantee for the service flow. The (R) AN network element and the terminal device itself do not sense the Mode information. In this way, the (R) AN network element and the terminal device can be reduced. Operational complexity.
