The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, which all belong to the embodiments of the present application. protected range.

支持5G能力的终端(5G终端)当在5G网络使用中有些业务不能使用时，可能会关闭5G能力；用户也可以手动关闭/打开5G终端的5G能力。目前在标准中讨论当5G能力关闭的时候，在4G网络建立了PDN connection后，如果5G能力又打开，此时4G网络中建立的PDN connection时候能够在5G网络中继续使用。Terminals that support 5G capabilities (5G terminals) may turn off 5G capabilities when some services cannot be used during the use of 5G networks; users can also manually turn off/on the 5G capabilities of 5G terminals. At present, it is discussed in the standard that when the 5G capability is turned off, after the 4G network establishes the PDN connection, if the 5G capability is turned on again, the PDN connection established in the 4G network at this time can continue to be used in the 5G network.

在3GPP SA2#143E会议中提案S2-2100902中采用的方法(方式一)是，当5G能力关闭时，在4G网络建立PDN connection的过程中，UE仍然分配5G***中的PDU会话标识(PDU session ID)，并将分配PDU session ID携带在协议配置选项(PCO，Protocol Configuration Option)中发送至PGW-C+SMF。The method (method 1) adopted in the proposal S2-2100902 in the 3GPP SA2#143E meeting is that when the 5G capability is turned off, in the process of establishing the PDN connection in the 4G network, the UE still allocates the PDU session identifier (PDU session identifier) in the 5G system. ID), and carry the allocated PDU session ID in the protocol configuration option (PCO, Protocol Configuration Option) and send it to the PGW-C+SMF.

在3GPP SA2#143E会议中提案S2-2100131中采用的方式(方式二)是，当5G能力关闭时，在4G网络建立PDN connection过程中，UE并不分配5G***中的PDU session ID。当5G能力再次开启后，UE再分配5G***中的PDU session ID，并触发UE请求承载资源修改(UE requested bearer resource modification)过程，在UE requested bearer resource modification过程中将分配的PDU session ID携带至PGW-C+SMF。The method adopted in the proposal S2-2100131 in the 3GPP SA2#143E meeting (method 2) is that when the 5G capability is turned off, the UE does not allocate the PDU session ID in the 5G system during the establishment of the PDN connection in the 4G network. When the 5G capability is enabled again, the UE re-allocates the PDU session ID in the 5G system, and triggers the UE request bearer resource modification (UE requested bearer resource modification) process, and carries the allocated PDU session ID to the UE requested bearer resource modification process. PGW-C+SMF.

上述PGW-C在获取PDU session ID后，都可以将UE移动至5G***所需使用的QoS参数、切片参数等信息在PCO中发送至UE。After obtaining the PDU session ID, the above-mentioned PGW-C can send the QoS parameters, slice parameters and other information required to move the UE to the 5G system to the UE in the PCO.

目前，当UE关闭(disable)5G能力后，UE在向MME发送的NAS MM消息(包括附着请求，TAU请求)中携带不支持5G能力的指示。在PDN connection建立过程中，MME会根据MM消息中的5G能力指示信息来决定选择仅供4G终端业务使用的PGW-C、还是供4G终端业务和5G终端业务使用的PGW-C+SMF。由于关闭5G能力后，UE向MME发送的是不支持5G能力的指示，MME可能会根据该指示，为该UE 选择PGW-C。这样即使按照上述两种方式提供了PDU session ID至PGW-C，当UE打开(Enable)5G能力后，UE移动至5G网络后，承载在该PDN connection的业务也不能保证连续性。本申请为了解决MME可能选择到PGW-C的问题。At present, after the UE disables the 5G capability, the UE carries an indication that the 5G capability is not supported in the NAS MM message (including the attach request and the TAU request) sent to the MME. During the establishment of the PDN connection, the MME will decide to select PGW-C for 4G terminal services only, or PGW-C+SMF for 4G terminal services and 5G terminal services according to the 5G capability indication information in the MM message. After the 5G capability is turned off, the UE sends an indication that the 5G capability is not supported to the MME, and the MME may select a PGW-C for the UE according to the indication. In this way, even if the PDU session ID is provided to the PGW-C according to the above two methods, when the UE enables (Enable) the 5G capability, after the UE moves to the 5G network, the continuity of the services carried on the PDN connection cannot be guaranteed. This application is to solve the problem that the MME may select the PGW-C.

该5G能力打开/关闭指示信息可以用于指示该终端设备的5G能力是否打开。The 5G capability on/off indication information may be used to indicate whether the 5G capability of the terminal device is turned on.

例如，如果终端设备支持5G能力、但5G能力没有打开，则该终端设备可以向网络设备发送第一消息，在该第一消息中携带终端能力指示信息和5G能力enable/disable指示信息；其中，该终端能力指示信息指示该终端设备支持5G能力，5G能力enable/disable指示信息指示该终端设备的5G能力已关闭。For example, if the terminal device supports the 5G capability but the 5G capability is not enabled, the terminal device may send a first message to the network device, and the first message carries the terminal capability indication information and the 5G capability enable/disable indication information; wherein, The terminal capability indication information indicates that the terminal device supports the 5G capability, and the 5G capability enable/disable indication information indicates that the 5G capability of the terminal device is disabled.

第一消息中的携带的终端能力指示信息可以供网络设备选择对应的网元。例如，在终端能力指示信息指示终端设备支持5G能力的情况下，该第一消息用于供网络设备选择第一网元。该第一网元可以是供4G终端业务和5G终端业务使用的网元，如PGW-C+SMF。又如，在终端能力指示信息指示终端设备不支持5G能力的情况下，该第一消息用于供网络设备选择第二网元。该第一网元可以是仅供4G终端业务使用的网元，如PGW-C。The terminal capability indication information carried in the first message can be used by the network device to select the corresponding network element. For example, when the terminal capability indication information indicates that the terminal device supports the 5G capability, the first message is used for the network device to select the first network element. The first network element may be a network element used for 4G terminal services and 5G terminal services, such as PGW-C+SMF. For another example, when the terminal capability indication information indicates that the terminal device does not support the 5G capability, the first message is used for the network device to select the second network element. The first network element may be a network element only used for 4G terminal services, such as PGW-C.

以终端设备支持5G能力、但没有打开5G能力为例，该终端设备向MME发送第一消息，在该第一消息中携带终端能力指示信息和5G能力enable/disable指示信息；其中，该终端能力指示信息指示该终端设备支持5G能力，5G能力enable/disable指示信息指示该终端设备的5G能力已关闭。MME根据该第一消息中携带的终端能力指示信息，可以为该终端设备选择合适的PGW-C+SMF，避免选择到PGW-C的情况。而在现有技术中，该终端设备会向MME发送不支持5G能力的终端能力指示信息；MME根据该终端能力指示信息，有可能为该终端设备选择到PGW-C。可见，相比现有技术，本申请实施例能够保证MME为终端设备选择合适的网元，避免后续出现PDU会话的业务不连续的情况。Taking the terminal device supporting the 5G capability but not enabling the 5G capability as an example, the terminal device sends a first message to the MME, and the first message carries the terminal capability indication information and the 5G capability enable/disable indication information; wherein, the terminal capability The indication information indicates that the terminal device supports the 5G capability, and the 5G capability enable/disable indication information indicates that the 5G capability of the terminal device is disabled. According to the terminal capability indication information carried in the first message, the MME can select an appropriate PGW-C+SMF for the terminal device, so as to avoid the situation of selecting the PGW-C. In the prior art, the terminal device will send the terminal capability indication information that does not support the 5G capability to the MME; the MME may select the PGW-C for the terminal device according to the terminal capability indication information. It can be seen that, compared with the prior art, the embodiment of the present application can ensure that the MME selects an appropriate network element for the terminal device, so as to avoid the situation that the service of the PDU session is discontinuous in the future.

在一些实施方式中，上述第一消息包括附着请求消息。上述第一消息还可以包括TAU请求消息。In some embodiments, the above-mentioned first message includes an attach request message. The above-mentioned first message may also include a TAU request message.

可选地，上述终端能力指示信息包括N1能力指示(N1 capability indication)信息。Optionally, the foregoing terminal capability indication information includes N1 capability indication (N1 capability indication) information.

以下举具体的实施例详细介绍本申请。The present application will be described in detail below with reference to specific embodiments.

实施例一：Example 1:

图3是本申请实施例一的实现流程图，在本实施例中，以网络设备为MME，第一消息为附着请求消息为例进行介绍。如图3所示，本实施例包括以下步骤：FIG. 3 is an implementation flowchart of Embodiment 1 of the present application. In this embodiment, the network device is an MME and the first message is an attach request message as an example for introduction. As shown in Figure 3, this embodiment includes the following steps:

S301：UE向MME发送附着请求(Attach request)消息，Attach request消息中携带N1 capability indication及5G能力enable/disable指示(Enable/Disable 5G capability indication)。其中，N1 capability indication用于指示UE是否支持5G能力，5G能力enable/disable指示用于指示UE的5G能力是否打开。例如，5G能力enable/disable指示的长度为1比特，该指示取值为“1”时，表示UE的5G能力已打开；该指示取值为“0”时，表示UE的5G能力已关闭。当N1 capability indication指示UE支持5G能力时，5G能力enable/disable指示的信息有效。当N1 capability indication指示UE不支持5G能力时，也就不存在5G能力是否打开的问题，因此5G能力enable/disable指示的信息无效。S301: The UE sends an Attach request (Attach request) message to the MME, and the Attach request message carries the N1 capability indication and the 5G capability enable/disable indication (Enable/Disable 5G capability indication). Among them, the N1 capability indication is used to indicate whether the UE supports the 5G capability, and the 5G capability enable/disable indication is used to indicate whether the 5G capability of the UE is turned on. For example, the length of the 5G capability enable/disable indication is 1 bit. When the indication is "1", it means that the 5G capability of the UE is enabled; when the indication is "0", it means that the 5G capability of the UE is disabled. When the N1 capability indication indicates that the UE supports the 5G capability, the information indicated by the 5G capability enable/disable is valid. When the N1 capability indication indicates that the UE does not support the 5G capability, there is no question of whether the 5G capability is enabled, so the information indicated by the 5G capability enable/disable is invalid.

在本实施例中，如果UE支持5G能力、且5G能力已关闭，则UE发送的Attach request消息中携带N1 capability indication和5G能力enable/disable指示；并且，N1capability indication指示UE支持5G能力，5G能力enable/disable指示UE的5G能力已关闭。In this embodiment, if the UE supports the 5G capability and the 5G capability is turned off, the Attach request message sent by the UE carries the N1 capability indication and the 5G capability enable/disable indication; and the N1 capability indication indicates that the UE supports the 5G capability and the 5G capability enable/disable indicates that the 5G capability of the UE is turned off.

S302：MME向UE返回附着接受(Attach Accept)消息，Attach Accept消息携带MME为该UE分配的全球唯一临时标识(GUTI，Globally Unique Temporary Identifier)。S302: The MME returns an Attach Accept (Attach Accept) message to the UE, where the Attach Accept message carries the Globally Unique Temporary Identifier (GUTI, Globally Unique Temporary Identifier) allocated by the MME for the UE.

S303：UE关闭5G能力(disable 5G capability)时，UE需要建立PDU连接(PDN connection)，UE可以向MME发送PDN connection建立请求消息，PDN connection建立请求消息携带接入点名称(APN，Access Point Name)等信息。进一步地，UE还可以为该PDU连接分配PDU会话标识(PDU session ID)，并将PDU session ID携带在PCO中，将PCO携带在PDN connection建立请求消息中发送至MME。S303: When the UE disables 5G capability (disable 5G capability), the UE needs to establish a PDU connection (PDN connection), the UE can send a PDN connection establishment request message to the MME, and the PDN connection establishment request message carries the access point name (APN, Access Point Name ) and other information. Further, the UE may also allocate a PDU session identifier (PDU session ID) to the PDU connection, carry the PDU session ID in the PCO, and carry the PCO in the PDN connection establishment request message and send it to the MME.

S304：MME根据Attach request消息中的N1 capability indication来进行选择，选择与PGW-C+SMF或PGW-C建立PDU连接。S304: The MME selects according to the N1 capability indication in the Attach request message, and selects to establish a PDU connection with PGW-C+SMF or PGW-C.

假定UE支持5G能力、且5G能力已关闭，那么UE发送的Attach request消息中携带的N1 capability indication指示UE支持5G能力。根据该N1 capability indication，MME能够为该UE选择合适的PGW-C+SMF。Assuming that the UE supports the 5G capability and the 5G capability is turned off, the N1 capability indication carried in the Attach request message sent by the UE indicates that the UE supports the 5G capability. According to the N1 capability indication, the MME can select a suitable PGW-C+SMF for the UE.

S305：在步骤S304选定合适的PGW-C+SMF之后，MME分配默认演进分组***承载标识(default EPS bearer id)及服务质量(QoS，Quality of Service)参数，并向选定的PGW-C+SMF发送会话建立请求消息，在该会话建立请求消息中携带default EPS bearer id和QoS参数。并且，MME还可以将步骤S303中收到的POC转发至该PGW-C+SMF。S305: After selecting the appropriate PGW-C+SMF in step S304, the MME allocates the default EPS bearer id (default EPS bearer id) and quality of service (QoS, Quality of Service) parameters, and sends them to the selected PGW-C +SMF sends a session establishment request message, which carries the default EPS bearer id and QoS parameters in the session establishment request message. In addition, the MME may also forward the POC received in step S303 to the PGW-C+SMF.

S306：PGW-C+SMF向MME返回会话建立响应消息。S306: The PGW-C+SMF returns a session establishment response message to the MME.

S307：MME向UE发送缺省承载建立请求消息，在该缺省承载建立请求消息中携带上述步骤S305中分配的default EPS bearer id和QoS参数。S307: The MME sends a default bearer establishment request message to the UE, where the default bearer establishment request message carries the default EPS bearer id and QoS parameters allocated in the above step S305.

S308：UE向MME返回缺省承载建立响应消息。S308: The UE returns a default bearer establishment response message to the MME.

通过上述过程，网络设备(如MME)根据UE发送的第一消息(如附着请求消息)中的N1 capability indication可以获知UE是否支持5G能力，并根据UE是否支持5G能力为UE选择适合的网元。在UE支持5G能力的情况下，网络设备为UE选择适合的PGW-C+SMF；在UE不支持5G能力的情况下，网络设备可以为UE选择PGW-C。从而避免了现有技术中网络设备有可能为支持5G能力的UE选择PGW-C的情况。Through the above process, the network device (such as MME) can know whether the UE supports 5G capability according to the N1 capability indication in the first message (such as the attach request message) sent by the UE, and select a suitable network element for the UE according to whether the UE supports the 5G capability. . In the case that the UE supports the 5G capability, the network device selects a suitable PGW-C+SMF for the UE; in the case that the UE does not support the 5G capability, the network device can select the PGW-C for the UE. Thus, the situation in the prior art that the network device may select the PGW-C for the UE supporting the 5G capability is avoided.

后续过程中，如果5G终端的5G能力打开或关闭的情况发生改变，则UE可以通知网络设备。例如，UE采用TAU请求消息或承载资源修改请求(bearer resource modification request)消息将5G能力打开/关闭指示信息发送至网络设备。In the subsequent process, if the 5G capability of the 5G terminal changes on or off, the UE may notify the network device. For example, the UE sends the 5G capability on/off indication information to the network device by using a TAU request message or a bearer resource modification request message.

例如，在一些实施方式中，上述方法还包括：For example, in some embodiments, the above method further includes:

终端设备打开5G能力；Terminal devices turn on 5G capabilities;

终端设备向网络设备发送第二消息，该第二消息中携带终端能力指示信息和5G能力打开/关闭指示信息；其中，该终端能力指示信息指示该终端设备支持5G能力，该5G能力打开/关闭指示信息用于指示该终端设备的5G能力已打开。The terminal device sends a second message to the network device, where the second message carries terminal capability indication information and 5G capability on/off indication information; wherein the terminal capability indication information indicates that the terminal device supports 5G capability, and the 5G capability is turned on/off The indication information is used to indicate that the 5G capability of the terminal device is turned on.

可选地，上述第二消息包括TAU请求。Optionally, the above-mentioned second message includes a TAU request.

上述过程是在5G终端在5G能力由关闭转换为打开的情况下，UE通知网络侧的一种实现方式。The above process is an implementation manner of the UE notifying the network side when the 5G terminal is switched from off to on of the 5G capability.

又如，在一些实施方式中，上述方法还包括：For another example, in some embodiments, the above method further includes:

终端设备关闭5G能力；The terminal equipment turns off 5G capability;

可选地，上述第三消息包括TAU请求。Optionally, the above-mentioned third message includes a TAU request.

上述过程是在5G终端在5G能力由打开转换为关闭的情况下，UE通知网络侧的一种实现方式。The above process is an implementation manner in which the UE notifies the network side when the 5G terminal is switched from on to off of the 5G capability.

实施例二：Embodiment 2:

本实施例主要介绍5G能力打开或关闭的情况发生改变时，UE如何通知网络设备。例如，5G终端在由5G能力打开的状态转变为5G能力关闭的状态时，向网络设备发送5G能力打开/关闭指示信息，使该5G能力打开/关闭指示信息指示5G能力已关闭；或者，5G终端在由5G能力关闭的状态转变为5G能力打开的状态时，向网络设备发送5G能力打开/关闭指示信息，使该5G能力打开/关闭指示信息指示5G能力已打开。This embodiment mainly introduces how the UE notifies the network device when the condition of being turned on or off of the 5G capability changes. For example, when the 5G terminal changes from the state of 5G capability on to the state of 5G capability off, it sends 5G capability on/off indication information to the network device, so that the 5G capability on/off indication information indicates that the 5G capability is turned off; or, 5G capability When the terminal changes from the 5G capability-off state to the 5G capability-on state, it sends the 5G capability on/off indication information to the network device, so that the 5G capability on/off indication information indicates that the 5G capability has been turned on.

图4是本申请实施例二的实现流程图，在本实施例中，以网络设备为MME为例进行介绍，UE采用TAU请求消息将5G能力打开/关闭指示信息发送至MME。如图4所示，本实施例包括以下步骤：FIG. 4 is a flow chart of the implementation of Embodiment 2 of the present application. In this embodiment, the network device is an MME as an example for introduction, and the UE uses a TAU request message to send 5G capability on/off indication information to the MME. As shown in Figure 4, this embodiment includes the following steps:

S401～S408，与实施例一中的步骤S301～S308相同，在此不再赘述。S401 to S408 are the same as steps S301 to S308 in the first embodiment, and are not repeated here.

S409：假定UE支持5G能力，并且在本步骤之前5G能力处于关闭状态。在本步骤中，UE打开5G能力，UE向MME发送TAU request消息，在TAU request消息中携带终端能力指示信息和5G能力打开/关闭指示信息，其中，终端能力指示信息指示该UE支持5G能力，5G能力打开/关闭指示信息指示该UE的5G能力已打开。S409: It is assumed that the UE supports the 5G capability, and the 5G capability is disabled before this step. In this step, the UE enables the 5G capability, the UE sends a TAU request message to the MME, and the TAU request message carries the terminal capability indication information and the 5G capability on/off indication information, wherein the terminal capability indication information indicates that the UE supports the 5G capability, The 5G capability on/off indication information indicates that the 5G capability of the UE is turned on.

S410：MME向PGW-C+SMF发送承载资源修改请求(bearer resource modification request)消息，该承载资源修改请求中携带5G能力打开/关闭指示信息。S410: The MME sends a bearer resource modification request (bearer resource modification request) message to the PGW-C+SMF, where the bearer resource modification request carries 5G capability on/off indication information.

通过S409和S410，实现了在5G终端的5G能力打开或关闭状态发生变化时，将最新的状态通知网络设备。当5G能力由打开状态转换为关闭状态时，UE也可以采用同样的方式通知网络设备。Through S409 and S410, when the 5G capability of the 5G terminal changes, the latest state is notified to the network device. When the 5G capability is switched from the on state to the off state, the UE can also notify the network device in the same way.

S411：PGW-C+SMF向MME返回承载资源修改响应消息。S411: The PGW-C+SMF returns a bearer resource modification response message to the MME.

S412：MME向UE返回TAU接受(TAU Accept)消息。S412: The MME returns a TAU Accept (TAU Accept) message to the UE.

S413：PGW-C+SMF在获知UE的5G能力重新打开后，PGW-C+SMF可以将UE在5G***中使用的QoS参数及切片参数等通过PCO发送给UE。例如，PGW-C+SMF向MME发送承载资源修改请求消息，在该承载资源修改请求消息中携带PCO，该PCO中携带UE在5G***中使用的QoS参数及切片参数等相关参数。S413: After the PGW-C+SMF learns that the 5G capability of the UE is reopened, the PGW-C+SMF can send the QoS parameters and slice parameters used by the UE in the 5G system to the UE through the PCO. For example, the PGW-C+SMF sends a bearer resource modification request message to the MME, and the bearer resource modification request message carries a PCO, and the PCO carries related parameters such as QoS parameters and slice parameters used by the UE in the 5G system.

S414：MME向UE发送承载资源修改请求消息，该承载资源修改请求消息中携带上述PCO。S414: The MME sends a bearer resource modification request message to the UE, where the bearer resource modification request message carries the above-mentioned PCO.

上述实施例一和实施例二中，支持5G能力的UE在关闭5G能力时，仍然分配了在5G***中使用的PDU会话标识，并将该PDU会话标识携带在PCO中发送至MME(如上述步骤S303)，再由MME将携带PDU会话标识的PCO转发至PGW-C+SMF(如上述步骤S305)。在本申请的其他实现方式中，在5G能力关闭的情况下，5G终端可以暂不分配在5G***中使用的PDU会话标识；待5G能力打开时，5G终端再分配PDU会话标识并发送至MME。In the above embodiments 1 and 2, when the 5G capability is turned off, the UE that supports the 5G capability still allocates the PDU session identifier used in the 5G system, and carries the PDU session identifier in the PCO and sends it to the MME (as described above). Step S303), and then the MME forwards the PCO carrying the PDU session identifier to the PGW-C+SMF (as in the above step S305). In other implementations of this application, when the 5G capability is turned off, the 5G terminal may temporarily not allocate the PDU session ID used in the 5G system; when the 5G capability is turned on, the 5G terminal will re-allocate the PDU session ID and send it to the MME .

具体地，在一些实施方式中，上述方法还可以包括：Specifically, in some embodiments, the above method may further include:

在终端设备的5G能力被关闭的情况下，终端设备向网络设备发送PDU会话建立请求消息或承载资源修改请求消息，该PDU会话建立请求消息或该承载资源修改请求消息中携带PCO，该PCO中携带终端设备分配的PDU会话标识ID。When the 5G capability of the terminal device is disabled, the terminal device sends a PDU session establishment request message or a bearer resource modification request message to the network device, where the PDU session establishment request message or the bearer resource modification request message carries a PCO, and the PCO contains It carries the PDU session ID assigned by the terminal device.

另外，上述承载资源修改请求消息中携带的PCO还可以携带5G能力打开/关闭指示信息。In addition, the PCO carried in the above bearer resource modification request message may also carry 5G capability on/off indication information.

实施例三：Embodiment three:

本实施例主要介绍5G终端在5G能力打开后，分配PDU会话标识并发送至网络侧的一种实现方式。在本实施例中，以网络设备为MME，第一消息为附着请求消息为例进行介绍。图5是本申请实施例三的实现流程图，如图5所示，本实施例包括以下步骤：This embodiment mainly introduces an implementation manner in which a 5G terminal allocates a PDU session identifier and sends it to the network side after the 5G capability is enabled. In this embodiment, the network device is an MME and the first message is an attach request message as an example for introduction. FIG. 5 is a flowchart of the implementation of Embodiment 3 of the present application. As shown in FIG. 5 , this embodiment includes the following steps:

S501：UE向MME发送附着请求(Attach request)消息，Attach request消息中携带N1 capability indication及5G能力enable/disable指示。其中，N1 capability indication用于指示UE是否支持5G能力，5G能力enable/disable指示用于指示UE的5G能力是否打开。S501: The UE sends an attach request (Attach request) message to the MME, and the Attach request message carries the N1 capability indication and the 5G capability enable/disable indication. Among them, the N1 capability indication is used to indicate whether the UE supports the 5G capability, and the 5G capability enable/disable indication is used to indicate whether the 5G capability of the UE is turned on.

步骤S501与上述步骤S301相同。Step S501 is the same as the above-mentioned step S301.

S502：MME向UE返回附着接受(Attach Accept)消息，Attach Accept消息携带MME为该UE分配的GUTI。步骤S502与上述步骤S302相同。S502: The MME returns an Attach Accept (Attach Accept) message to the UE, where the Attach Accept message carries the GUTI allocated by the MME for the UE. Step S502 is the same as the above-mentioned step S302.

S503：当UE关闭5G能力(disable 5G capability)时，UE需要建立PDU连接(PDN connection)，UE可以向MME发送PDN connection建立请求消息，PDN connection建立请求消息携带APN等信息。当前，UE暂不分配PDU会话标识。S503: When the UE disables the 5G capability (disable 5G capability), the UE needs to establish a PDU connection (PDN connection), and the UE can send a PDN connection establishment request message to the MME, and the PDN connection establishment request message carries the APN and other information. Currently, the UE does not allocate a PDU session identifier for the time being.

S504～S512，与上述S404～S412，在此不再赘述。S504-S512 and the above-mentioned S404-S412 will not be repeated here.

S513：由于UE在步骤S503中未分配PDU会话标识，在本步骤中，UE分配PDU会话标识(PDU session ID)，并将PDU session ID携带在PCO中，将PCO携带在承载资源修改请求消息中发送至MME。S513: Since the UE does not allocate a PDU session identifier in step S503, in this step, the UE allocates a PDU session identifier (PDU session ID), carries the PDU session ID in the PCO, and carries the PCO in the bearer resource modification request message Sent to MME.

S514：MME向PGW-C+SMF发送承载资源修改命令(bearer resource modification command)消息，在该消息中携带上述PCO。S514: The MME sends a bearer resource modification command (bearer resource modification command) message to the PGW-C+SMF, where the message carries the above-mentioned PCO.

可见，通过步骤S513和S514，UE将分配的PDU会话标识通知网络侧。It can be seen that through steps S513 and S514, the UE notifies the network side of the allocated PDU session identifier.

S515：PGW-C+SMF在获知UE的5G能力重新打开后，PGW-C+SMF可以将UE在5G***中使用的QoS参数及切片参数等通过PCO发送给UE。例如，PGW-C+SMF发送承载资源修改请求消息，在该承载资源修改请求消息中携带PCO，该PCO中携带UE在5G***中使用的QoS参数及切片参数等相关参数。S515: After the PGW-C+SMF learns that the 5G capability of the UE is reopened, the PGW-C+SMF can send the QoS parameters and slice parameters used by the UE in the 5G system to the UE through the PCO. For example, the PGW-C+SMF sends a bearer resource modification request message, and the bearer resource modification request message carries a PCO, and the PCO carries related parameters such as QoS parameters and slice parameters used by the UE in the 5G system.

S516：MME向UE发送承载资源修改请求消息，该承载资源修改请求消息中携带上述PCO。S516: The MME sends a bearer resource modification request message to the UE, where the bearer resource modification request message carries the above-mentioned PCO.

S517：UE向MME返回承载资源修改接受消息。S517: The UE returns a bearer resource modification accept message to the MME.

S518：MME向PGW-C+SMF返回承载资源修改响应消息。S518: The MME returns a bearer resource modification response message to the PGW-C+SMF.

以上实施方式中，介绍了UE如何更为精确地上报自身的5G能力，从而使得MME可以为UE选择到合适的PGW-C+SMF。具体地，将5G能力划分为是否支持5G能力和是否打开5G能力两个维度。采用这种方式，支持5G能力但当前未打开5G能力的终端上报的信息与不支持5G能力的终端上报的信息是不同的，网络设备能够根据终端上报的信息区分这两种不同的终端。而在现有技术中，前述两种终端上报的信息相同，网络设备无法区分前述两种终端，因此可能会为支持5G能力但暂未打开5G能力的终端选择到PGW-C，无法保证承载在PDU连接的业务的连续性。In the above embodiments, it is introduced how the UE reports its own 5G capability more accurately, so that the MME can select a suitable PGW-C+SMF for the UE. Specifically, 5G capabilities are divided into two dimensions: whether to support 5G capabilities and whether to enable 5G capabilities. In this way, the information reported by a terminal that supports 5G capability but does not currently have 5G capability enabled is different from the information reported by a terminal that does not support 5G capability. The network device can distinguish between the two different terminals according to the information reported by the terminal. In the prior art, the information reported by the aforementioned two terminals is the same, and the network equipment cannot distinguish the aforementioned two terminals. Therefore, PGW-C may be selected for terminals that support 5G capabilities but have not yet turned on 5G capabilities. Continuity of service to which the PDU is connected.

本申请实施例还提出一种终端能力接收方法，图6是根据本申请实施例的一种终端能力接收方法600的示意性流程图，该方法可选地可以应用于图1所示的***，如应用于网络设备，但并不仅限于此。该方法包括以下内容的至少部分内容。An embodiment of the present application also proposes a method for receiving terminal capabilities. FIG. 6 is a schematic flowchart of a method 600 for receiving terminal capabilities according to an embodiment of the present application. The method can optionally be applied to the system shown in FIG. 1 . Such as applied to network equipment, but not limited to this. The method includes at least some of the following.

S610：网络设备从终端设备接收第一消息，该第一消息中携带终端能力指示信息和5G能力打开/关闭指示信息；其中，S610: The network device receives a first message from the terminal device, where the first message carries terminal capability indication information and 5G capability on/off indication information; wherein,

该终端能力指示信息用于指示终端设备是否支持5G能力；The terminal capability indication information is used to indicate whether the terminal device supports 5G capability;

该5G能力打开/关闭指示信息用于指示终端设备的5G能力是否打开。The 5G capability on/off indication information is used to indicate whether the 5G capability of the terminal device is turned on.

网络设备可以根据上述终端能力指示信息为终端设备选择合适的网元。The network device may select an appropriate network element for the terminal device according to the above-mentioned terminal capability indication information.
