Abstract
A method and a system for selecting network equipment are provided. The method includes: selecting a primary pool or a pool with the highest priority from preset information when UE needs to select network equipment; and selecting the network equipment for the UE from the selected primary pool or pool with the highest priority. Thus, the relocation times of an MME and a serving SAE gateway are effectively reduced and an operation efficiency of a network is enhanced. Meanwhile, the UE having or subscribing a new service function selects to be attached to the network equipment with the new service function within a pool, such that the diversity demands for service development are satisfied, and the equipment overhead is saved.
Claims16
A method for an evolved nodeB (ENB) selecting a core network (CN) equipment for a user equipment (UE), wherein the ENB is connected with multiple pools of CN equipment, the method comprising:
- receiving, by the ENB, a first message sent from the UE;
- determining, by the ENB, whether the ENB has a connection to a first CN equipment to which the UE registered previously, according to the received first message;
- if the ENB has no connection to the first CN equipment to which the UE registered previously:
- selecting, by the ENB, a first pool having a lowest probability of CN equipment relocation in the multiple pools;
- and
- selecting, by the ENB, a second CN equipment for the UE from the selected first pool;
- if the ENB has the connection to the first CN equipment:
- selecting, by the ENB, the first CN equipment for the UE.
An evolved nodeB (ENB), which is connected with multiple pools of core network (CN) equipment, comprising:
- a receiver, configured to receive a first message sent from the UE;
- a processor, configured to determine whether the ENB has a connection to a first CN equipment to which the UE registered previously, according to the received first message, select a first pool having a lowest probability of CN equipment relocation in the multiple pools if the ENB has no connection to the first CN equipment to which the UE registered previously and select the second CN equipment for the UE from the selected first pool;
- and select the first CN equipment for the UE if the ENB has the connection to the first CN equipment.
A system for selecting a core network (CN) equipment, comprising an evolved nodeB (ENB) and a user equipment (UE), wherein the ENB is connected with multiple pools of CN equipment;
- wherein the UE is configured to send a first message to the ENB;
- and
- the ENB is configured to receive the first message sent from the UE;
- determine whether the ENB has a connection to a first CN equipment to which the UE registered previously according to the received first message;
- if the ENB has no connection to the first CN equipment to which the user equipment registered previously, select a first pool having a lowest probability of CN equipment relocation in the multiple pools and select a second CN equipment for the UE from the selected first pool;
- and if the ENB has the connection to the first CN equipment, select the first CN equipment for the UE.
