图2为本申请提供的网络切片处理方法实施例一的信令交互图。如图2所示，本申请提供的网络切片处理方法包括如下步骤：FIG. 2 is a signaling interaction diagram of Embodiment 1 of a network slice processing method provided by the present application. As shown in FIG. 2, the network slice processing method provided by the present application includes the following steps:
S201：终端设备接入源网络切片。S201: The terminal device accesses the source network slice.
具体地，终端设备可以向网络管理器发送接入请求，网络管理器根据接入请求对终端设备进行接入授权，并发送配置信息，终端设备根据配置信息进行配置以接入源网络切片。Specifically, the terminal device may send an access request to the network manager, and the network manager performs access authorization on the terminal device according to the access request, and sends configuration information, and the terminal device configures according to the configuration information to access the source network slice.
本申请中的源网络切片为终端设备当前已经接入的网络切片。The source network slice in this application is a network slice that the terminal device has currently accessed.
在一种实现方式中，在接入源网络切片时，接入请求中可以只包括终端设备的标识。此时，网络切片管理器获取与终端设备的标识对应的默认网络切片，对终端设备进行默认网络切片接入授权，获取与其对应的协议配置信息，发送给终端设备。终端设备根据与默认网络切片对应的协议配置信息进行配置以接入默认网络切片。需要说明的是，默认网络切片是终端设备签约时确定的能满足终端设备最基本业务需求的网络切片。In an implementation manner, when accessing the source network slice, the access request may include only the identifier of the terminal device. At this time, the network slice manager obtains a default network slice corresponding to the identifier of the terminal device, performs default network slice access authorization on the terminal device, and obtains protocol configuration information corresponding thereto, and sends the protocol configuration information to the terminal device. The terminal device is configured to access the default network slice according to protocol configuration information corresponding to the default network slice. It should be noted that the default network slice is a network slice that is determined when the terminal device signs up to meet the basic service requirements of the terminal device.
在另一种实现方式中，在接入源网络切片时，接入请求中包括终端设备根据自身需要进行的业务确定的需要接入的源网络切片的标识。由于这时终端设备还未接入源网络切片，将该标识称为待接入标识，对应的源网络切片称为待接入网络切片。此时，网络切片管理器根据待接入标识进行对终端设备进行待接入网络切片接入授权，获取与其对应的协议配置信息，发送给终端设备，终端设备根据与待接入网络切片对应的协议配置信息进行配置以接入待接入网络切片。In another implementation manner, when accessing the source network slice, the access request includes an identifier of the source network slice that needs to be accessed by the terminal device according to the service that is required by the terminal device. Since the terminal device does not access the source network slice at this time, the identifier is referred to as the to-be-accessed identifier, and the corresponding source network slice is referred to as the to-be-accessed network slice. At this time, the network slice manager performs the network slice access authorization for the terminal device to be accessed according to the to-be-accessed identifier, and obtains the protocol configuration information corresponding thereto, and sends the protocol configuration information to the terminal device, and the terminal device according to the slice to be accessed according to the network slice to be accessed. The protocol configuration information is configured to access the network slice to be accessed.
S202：终端设备向网络管理器发送网络切片处理请求，网络管理器接收终端设备发送的网络切片处理请求。S202: The terminal device sends a network slice processing request to the network manager, and the network manager receives the network slice processing request sent by the terminal device.
其中，网络切片处理请求包括目标标识。终端设备已接入源网络切片。终端设备向网络管理器发送网络切片处理请求，网络切片处理请求用于指示网络管理器根据网络切片处理请求，对终端设备进行目标标识对应的目标网络切片接入授权，并获取与目标网络切片对应的第一协议配置信息。The network slice processing request includes a target identifier. The terminal device has access to the source network slice. The terminal device sends a network slice processing request to the network manager, where the network slice processing request is used to instruct the network manager to perform the target network slice access authorization corresponding to the target identifier of the terminal device according to the network slice processing request, and obtain the mapping corresponding to the target network slice. The first protocol configuration information.
网络切片处理请求中可以包括处理请求类型的标识，用以指示网络切片处理请求是何种类型。在本申请中，网络切片处理请求可以为网络切片切换请求或网络切片接入请求。终端设备上可以运行不同的业务，本申请提供的网络切片处理方法中，终端设备已经接入了一个源网络切片以运行一种业务，并且，目标网络切片与控制面的连接已经建立。举例来说，在第一种情况中：终端设备已经接入一个源网络切片运行语音业务，此时，如果终端设备需要结束语音业务进行连接智能电表读取电的度数的业务时，由于当前的源网络切片适用于运行语音业务，该源网络切片的特性为延迟小、安全性较低同时可靠性也较低，而连接智能电表读取电的度数时，该业务对安全性和可靠性要求较高，因此，终端设备需要从当前源网络切片切换至能运行读取智能电表上的电的度数的目标网络切片上。在第二种情况中，终端设备需要在不结束语音业务的情况下连接智能电表读取电的度数，终端设备需要接入能满足读取电的度数业务需求的目标网络切片中，且同时也接入运行语音业务的 源网络切片。在第一种情况中，网络切片处理请求为网络切片切换请求。在第二种情况中，网络切片处理请求为网络切片接入请求。终端设备和网络管理器可以预先约定规则以使网络管理器识别网络切片处理请求的类型。The network slice processing request may include an identifier of the processing request type to indicate what type of network slice processing request is. In the present application, the network slice processing request may be a network slice handover request or a network slice access request. Different services can be run on the terminal device. In the network slice processing method provided by the application, the terminal device has accessed a source network slice to run a service, and the connection between the target network slice and the control plane has been established. For example, in the first case, the terminal device has access to a source network slice to run the voice service. At this time, if the terminal device needs to end the voice service and connect the smart meter to read the power of the power, due to the current The source network slice is suitable for running voice services. The characteristics of the source network slice are small delay, low security, and low reliability. When the smart meter is connected to read the power, the service requires security and reliability. Higher, therefore, the terminal device needs to switch from the current source network slice to the target network slice that can run the degree of reading the power on the smart meter. In the second case, the terminal device needs to connect the smart meter to read the degree of power without ending the voice service, and the terminal device needs to access the target network slice that can meet the service demand of the read power, and also Access to running voice services Source network slice. In the first case, the network slice processing request is a network slice handover request. In the second case, the network slice processing request is a network slice access request. The terminal device and the network manager can pre-agreed rules to cause the network manager to identify the type of network slice processing request.
在终端设备需要运行新的业务且当前的源网络切片不能满足该新业务的需求时，终端设备向网络管理器发送网络切片处理请求。目标网络切片为终端设备待接入或待切换至的网络切片。When the terminal device needs to run a new service and the current source network slice cannot meet the requirement of the new service, the terminal device sends a network slice processing request to the network manager. The target network slice is a network slice to which the terminal device is to be accessed or to be switched.
目标标识可以是目标网络切片的标识。终端设备可以查询自身存储的业务与网络切片的映射关系，根据自身将要运行的目标业务类型确定目标网络切片，从而获取目标网络切片的标识。或者，终端设备查询自身存储的业务类型的标识与网络切片的标识的映射关系，根据自身将要运行的目标业务类型确定目标网络切片的标识。The target identifier can be the identity of the target network slice. The terminal device can query the mapping relationship between the stored service and the network slice, and determine the target network slice according to the target service type that is to be run, so as to obtain the identifier of the target network slice. Alternatively, the terminal device queries the mapping relationship between the identifier of the service type stored by itself and the identifier of the network slice, and determines the identifier of the target network slice according to the target service type to be run by itself.
目标标识还可以是目标业务类型的标识。终端设备可以查询自身存储的目标业务类型与目标业务类型的标识的映射关系，根据自身将要运行的目标业务类型确定目标业务类型的标识。The target identity can also be an identity of the target service type. The terminal device can query the mapping relationship between the target service type and the identifier of the target service type, and determine the identifier of the target service type according to the target service type to be run.
需要说明的是，终端设备可以先将网络切片处理请求发送给源网络切片中的eNB。源网络切片中的eNB再将网络切片处理请求发送给控制面的MME。MME再将网络切片处理请求发送给网络管理器。网络管理器接收MME发送的网络切片处理请求。It should be noted that the terminal device may first send a network slice processing request to the eNB in the source network slice. The eNB in the source network slice then sends a network slice processing request to the MME of the control plane. The MME then sends a network slice processing request to the network manager. The network manager receives the network slice processing request sent by the MME.
S203：网络管理器根据网络切片处理请求，对终端设备进行目标标识对应的目标网络切片接入授权，并获取与目标网络切片对应的第一协议配置信息。S203: The network manager performs the target network slice access authorization corresponding to the target identifier on the terminal device according to the network slice processing request, and acquires first protocol configuration information corresponding to the target network slice.
具体地，在一种实现方式中，目标标识为目标网络切片的标识。网络管理器中存储有终端设备的签约信息，根据终端设备的签约信息以及目标网络切片的标识对终端设备进行目标网络切片的标识对应的目标网络切片接入授权。Specifically, in one implementation, the target identifier is an identifier of the target network slice. The network manager stores the subscription information of the terminal device, and performs the target network slice access authorization corresponding to the identifier of the target network slice according to the subscription information of the terminal device and the identifier of the target network slice.
在另外一种实现方式中，目标标识为目标网络切片的标识，终端设备发送的网络切片处理请求中还包括终端设备的标识。举例来说，终端设备的标识可以是国际移动用户识别码(International Mobile Subscriber Identification Number；简称：IMSI)等。网络管理器在接收到网络切片处理请求后，根据网络切片处理请求中终端设备的标识从HSS中或者PCRF中获取与终端设备的标识对应的签约信息。若网络管理器根据签约信息及目标网络切片的标识确定终端设备能接入目标网络切片，则对终端设备进行目标网络切片的标识对应的目标网络切片接入授权。这里的签约信息可以是终端设备在入网时签约的可以发起业务的类型、数据传输速率、带宽、时延及误包率等信息。In another implementation manner, the target identifier is an identifier of the target network slice, and the network slice processing request sent by the terminal device further includes an identifier of the terminal device. For example, the identifier of the terminal device may be an International Mobile Subscriber Identification Number (IMSI) or the like. After receiving the network slice processing request, the network manager obtains the subscription information corresponding to the identifier of the terminal device from the HSS or the PCRF according to the identifier of the terminal device in the network slice processing request. If the network manager determines that the terminal device can access the target network slice according to the subscription information and the identifier of the target network slice, the terminal device performs the target network slice access authorization corresponding to the identifier of the target network slice. The subscription information here may be information such as the type of the service that the terminal device can sign when entering the network, the data transmission rate, the bandwidth, the delay, and the packet loss rate.
在又一种实现方式中，目标标识为目标业务类型的标识，且网络切片处理请求还包括终端设备的标识。网络管理器在接收到网络切片处理请求后，根据网络切片处理请求中终端设备的标识从HSS中或者PCRF中获取与终端设备的标识对应的签约信息。若网络管理器根据签约信息及目标业务类型的标识确定终端设备能接入目标网络切片，则对终端设备进行目标业务类型的标识对应的目标网络切片接入授权。In still another implementation manner, the target identifier is an identifier of the target service type, and the network slice processing request further includes an identifier of the terminal device. After receiving the network slice processing request, the network manager obtains the subscription information corresponding to the identifier of the terminal device from the HSS or the PCRF according to the identifier of the terminal device in the network slice processing request. If the network manager determines that the terminal device can access the target network slice according to the subscription information and the identifier of the target service type, the terminal device performs the target network slice access authorization corresponding to the identifier of the target service type.
需要说明的是，当网络管理器中的切片管理器和SDPC位于同一个实体时，即集成在一起时，网络管理器在对终端设备进行接入授权后，可以从自身获取目标网络 切片对应的第一协议配置信息。当网络管理器中的切片管理器和SDPC分开设置于不同的实体时，切片管理器根据网络切片处理请求，对终端设备进行接入授权，之后，切片管理器将网络切片处理请求发送给SDPC，SDPC确定目标网络切片对应的第一协议配置信息，再将该第一协议配置信息发送给切片管理器。It should be noted that when the slice manager and the SDPC in the network manager are located in the same entity, that is, when the network manager integrates with the terminal device, the network manager can obtain the target network from itself. The corresponding first protocol configuration information is sliced. When the slice manager and the SDPC in the network manager are separately set to different entities, the slice manager performs access authorization on the terminal device according to the network slice processing request, and then the slice manager sends the network slice processing request to the SDPC.
