Registration zone updating method and apparatus

Abstract

The present invention discloses a method for updating registration area, wherein the method comprises the following steps: when a user terminal UE enters a new registration area or a plurality of registration areas exist for selection, determining whether the updating condition of registration area is satisfied; and when the updating condition is satisfied, initiating the updating to a new registration area or another registration area by the UE. The invention also discloses a device which is used for updating the registration area. The embodiment of the invention sets different updating conditions of registration area for the UE in the registration area, so that only the UE satisfying the updating condition initiates the registration area updating. The registering process of simultaneously initiating of large number of UEs to the new registration area is effectively prevented. Not only is the load of system signaling reduced, but also the consumption of wireless interface resource and network resource can be reduced. The possibility of affecting the service quality of subscriber communication service is reduced and the system performance is increased.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a method and equipment for updating a registration area. Background technique [0002] In the existing 2G / 3G network, after the UE (User Equipment, user terminal) selects or reselects a Cell (cell), it registers with the core network, and the SGSN (Serving GPRS SupportNode, serving GPRS support node) or MSC in the network (Mobile Switch Centre, mobile switching center) will allocate a registration area to UE, namely LA (LocationArea, location area) or RA (RoutingArea, routing area). Among them, MSC allocates LA to UE, which corresponds to CS domain service; SGSN allocates RA to UE, corresponding to PS domain service, and RA is equal to LA or a subset of LA. If the UE moves, an LAU (Location Area Update, location area update) or RAU (Routing Area Update, routing area update) process must be initiated immediately every time the LA or RA is changed. Of course, if the UE d...

Problems solved by technology

Therefore, according to the existing technology, when these UEs continue to move to TA8, location updates will still occur almost simultaneously, resulting in a sudden high load on the system

[0031] It can be seen that although TAList can cross MMEs, it is still limited to MME Pools, that is, when crossing the boundaries of Pools, there will still be a large number of UEs that initiate location updates almost simultaneously, resulting in congestion. Therefore, this method cannot fundamentally Solve the problem of high system load caused by a large number of mobile users registering at the same time
