The embodiments of the present invention are described in detail below.

2 is a flowchart of a method for managing subscription data of a user equipment according to an embodiment of the present invention. Referring to FIG. 2, the method includes: 201: The mobility management network element receives a registration request message of the standby user equipment, where the registration request message includes an identifier of the primary user equipment.

In this embodiment, the registration request message of the user equipment Slave UE may be sent to the mobility management network element by the primary user equipment Master UE, or may be directly sent by the standby user equipment Slave UE to the mobility management network element.

If the slave UE directly sends the registration request message to the mobility management network element, the master UE first notifies the slave UE of its identity. For example, the master UE notifies the slave UE of its identity through the Zigbee protocol, so that the slave UE will use the Master UE. The identifier is included in the sent registration request message, where the Slave UE may first notify the Master UE of its own radio access capability. If the Slave UE has the radio access capability, the Master UE notifies the Slave UE of its identity. The wireless access capability refers to whether the Slave UE is a TE (Terminal Equipment) or an ME (Mobile Equipment). If it is a TE, the Slave UE does not have the radio access capability. If it is an ME, the Slave. The UE has the radio access capability. If the slave UE sends the registration request to the mobility management network element through the master UE, the master UE includes its own identifier in the registration request message when forwarding the registration request message of the slave UE.

In this embodiment, the registration request message may be an Attach Request message, a RAU Request message, a LAU Request message, or a TAU Request message. This embodiment is not intended to be limiting. The registration request message carries the identifier of the Slave UE and the identifier of the Master UE. For example, the registration request message includes a Linked UE identity element, where the message includes the identifier of the Master UE.

In this embodiment, the identifier of the user equipment (the identifier of the primary user equipment or the identifier of the standby user equipment) includes an IMSI (International Mobile Subscriber Identity), and an MSISDN (Mobile Station International ISDN Number). Number), IMEI (International Mobile Equipment Identity), NAI (Network Access Identifier), TMSI (Temporary Mobile) Subscriber Identity, Temporary Mobile Subscriber Identifier, P-TMSI (Packet Temporary Mobile Subscriber Identity), or GUTI (Globally Unique Temporary Identity), etc. limit.

202: The mobility management network element acquires subscription data of the primary user equipment according to the identifier of the primary user equipment, and applies the subscription data to the standby user equipment.

In this embodiment, the mobility management network element receives the registration request message of the slave UE, obtains the identity of the master UE from the registration request message, and obtains the subscription data of the master user equipment Master UE according to the identity of the master UE (ie, the group The subscription data is applied to the slave UE, that is, the Slave UE also uses the subscription data of the Master UE, that is, the group or user equipment group uses the subscription data of the Master UE.

When the primary user equipment is registered to the mobility management network element, the mobility management network element obtains the subscription data of the primary user equipment from the subscription database, and saves, so that the mobility management network element is from the subscription data of the saved primary user equipment. You can get the subscription data of the primary user device.

In this embodiment, the mobility management network element may further associate the Master UE and the Slave UE according to the identity of the Master UE included in the registration request message of the Slave UE to form a group.

The association refers to binding the primary user equipment and the standby user equipment into a group to implement group management. For example, the Master UE and the Slave UE are bound together by a list, that is, the Master UE and the Slave UE are set up in the same list, and are identified as the same group, as shown in the following table, where the Slave UE can be one. Or multiple. The above is only an example, and the present embodiment is not limited thereto, and the meanings of the related ones are the same in the following description, and will not be described again. Primary user equipment identity

The standby user device 1 identifies the standby user device n identifier. For the group, the mobility management network element uses the subscription data of the Master UE as the subscription data of the group, and all the UEs in the gp, Group use the subscription data, so that the subscription database is still based on the UE level (ie, The Master UE) is contracted, so there is no need to modify the subscription data structure in the subscription database. At the same time, the mobility management network element is based on the Group for contract data management. gp, the mobility management network element uses the subscription data of the Master UE as the subscription data. For the contract data of the group, the mobility management network element only needs to obtain the subscription data of the Master UE in the subscription database. For the Slave UE, the mobility management network element does not need to interact with the subscription database (HSS/HLR) to obtain the subscription of the Slave UE. The data greatly reduces the signaling interaction between the mobility management network element and the subscription database, and greatly reduces the processing load of the mobility management network element and the subscription database.
