Title: USER EQUIPMENT MANAGEMENT METHOD, DEVICE AND SYSTEM
Abstract:
Provided in an embodiment of the present invention are a UE management method, device and system, the method comprising: a first MME determines whether a UE accessing the first MME is a UE covered by a second MME pool, the first MME being located in a first MME pool, and the first MME pool being a backup MME pool of the second MME pool; and if the UE accessing the first MME is a UE covered by the second MME pool, and the second MME pool is in a normal state, then the first MME uninstalls the UE. That is, when the MME in the first MME pool determines that the UE accessing same is from the second MME pool, and the second MME pool returns to normal, the MME in the first MME pool uninstalls the UE from the second MME pool. Therefore, in an RRC establishment process, the UE will not carry the information of the MME in the first MME pool, such that an eNB selects, according to the policy thereof, an MME in the second MME pool for the UE to establish S1-MME connection, and the UE can return to the second MME pool, thus avoiding failed migration of the UE from a backup MME pool to a local MME pool.
