Method for allocating UE identity, network device, UE, and computer storage medium
View Patent ↗A method for allocating a User Equipment (UE) identity, a network device, a UE and a computer storage medium are provided. The method includes: the network device allocates, based on a Tracking Area (TA) where the UE is located, unique identity information within the TA to the UE; and sends, to the UE, the unique identity information within the TA which is allocated to the UE.
1. A method for allocating a User Equipment (UE) identity, executed by a network device, the method comprising:
allocating a Tracking Area (TA) list to a UE and allocating, for each TA in the TA list, unique identity information of the UE within the TA to the UE, when the UE is performing an attach procedure or a location area update procedure; and
sending, to the UE, the TA list and the respective unique identity information of the UE within each TA in the TA list, through an attach response message when the UE is performing the attach procedure or through a location update response message when the UE is performing the location area update procedure.
2. The method of claim 1 , further comprising:
determining a base station corresponding to the UE according to the TA list when a paging message for the UE is to be sent; and
sending a paging trigger message to the base station corresponding to the UE, and carrying, in the paging trigger message, the unique identity information of the UE within the TA in the TA list corresponding to the base station, wherein the unique identity information of the UE within the TA corresponding to the base station causes the base station to generate and send the paging message for the UE.
3. The method of claim 1 , further comprising:
acquiring TA information of a cell where the UE is located and the unique identity information of the UE within the TA in the TA list, when the UE initiates an initial Radio Resource Control (RRC) connection establishment; and
addressing context information of the UE based on the unique identity information of the UE within the TA carried in a RRC connection request message and the TA information.
4. The method of claim 1 , wherein the network device is a device in a core network.
5. A method for allocating a User Equipment (UE) identity, executed by a UE, the method comprising:
acquiring, from a network device, a Tracking Area (TA) list and respective unique identity information of the UE within each TA in the TA list through an attach response message when the UE is performing an attach procedure or through a location update response message when the UE is performing a location area update procedure.
6. The method of claim 5 , further comprising:
detecting, based on unique identity information within a TA in the TA list of a cell where the UE is located, whether a base station corresponding to the UE sends a paging message for the UE.
7. A network device, comprising: a processor and a network interface, wherein
a processor is configured to allocate, a Tracking Area (TA) list to User Equipment (UE) and allocate, for each TA in the TA list, unique identity information of the UE within the TA to the UE, when the UE is performing an attach procedure or a location area update procedure; and
invoke the network interface to send, to the UE, the TA list and the respective unique identity information of the UE within each TA in the TA list, through an attach response message when the UE is performing an attach procedure, or through a location update response message when the UE is performing a location area update procedure.
8. The network device of claim 7 , wherein the processor is configured to determine a base station corresponding to the UE according to the TA list when a paging message for the UE is to be sent; and
invoke the network interface to send a paging trigger message to the base station corresponding to the UE, and carries, in the paging trigger message, the unique identity information of the UE within the TA in the TA list corresponding to the base station, wherein the unique identity information of the UE within the TA corresponding to the base station causes the base station to generate and send the paging message for the UE.
9. The network device of claim 7 , wherein the processor is configured to acquire TA information of a cell where the UE is located and the unique identity information of the UE within the TA in the TA list, when the UE initiates an initial Radio Resource Control (RRC) connection establishment; and address context information of the UE based on the unique identity information of the UE within the TA carried in a RRC connection request message and the TA information.
10. The network device of claim 7 , wherein the network device is a device in a core network.
11. User Equipment (UE), comprising: a processor and a network interface, wherein
the processor is configured to invoke the network interface to perform the method for allocating a UE identity according to claim 5 .
12. The UE of claim 11 , wherein the processor is configured to detect, based on unique identity information within a TA in the TA list of a cell where the UE is located, whether a base station corresponding to the UE sends a paging message for the UE.
13. A non-transitory computer storage medium, having stored thereon computer executable instructions that, when executed by a processor of a network device, cause the network device to implement the method of claim 1 .
14. A non-transitory computer storage medium, having stored thereon computer executable instructions that, when executed by a processor of User Equipment (UE), cause the UE to implement the method of claim 5 .
