Abstract
The invention discloses a location area updating management method, a mobile management entity and a network system, wherein the location area updating management method comprises the following steps: receiving indication information of the location area that an indication terminal locates currently by the mobile management entity; and initiating a terminal location area updating request and indicating a mobile switching center corresponding to the location area that the terminal locates currently to be associated with the mobile management entity by the mobile management entity according to the indication information. By adopting the invention, the problem of service failure under the situation that the location area and a tracking area are not overlapped can be avoided on the basis of not increasing extra service establishing time.
Description
Technical field
The present invention relates to field of mobile communication, relate in particular to a kind of location area updating management method, Mobility Management Entity and network system.
Background technology
Rollback CS (CSFB, Circuit Switched Fall Back) refers to the user attached to System Architecture Evolution (SAE, System Architecture Evolution) during network, if carry out CS (CircuitSwitched) professional (as answer or call), then switch to the CS network in the 2G/3G system, after business is finished, switch back to SAE again.For supporting CSFB, require the Mobility Management Entity (MME in the evolution network framework, Mobility Management Entity) and (MSC of mobile switching centre in the 2G/3G system, Mobility Switch Corner) to set up association between, this is related by the foundation of SGs interface, the SGs interface class is like Gs interface of the prior art, as user during attached to MME, MME initiates registration by the SGs interface to MSC, set up the association of user between MME and MSC, if the user separates from MME, then MME deletes this user's who is created among the MSC association by the SGs interface.
When supporting CSFB, require tracking area (the Tracking Area of the position correspondence at user place, TA) and lane place (Location Area, LA) follow MME and the MSC correspondence that the user registered, but because LA and TA overlay area is uncertain, can cause the border of LA and TA not overlapping, thereby cause situation as shown in Figure 1, user terminal (UE, User Equipment) (2 when moving to tracking area 3 from tracking area, corresponding MME is a Mobility Management Entity 1, it is related that Mobility Management Entity 1 selects corresponding M SC mobile switching centre 1 to create, but when the user moved to position shown in the arrow, this moment, corresponding lane place was lane place LA4, and lane place 4 is mobile switching centre 2 pairing lane place, if CSFB takes place in this position in the user, message will send to mobile switching centre 2, and mobile switching centre 2 does not have user's log-on message, therefore can cause service fail.
For addressing the above problem, prior art has proposed to roam among the use CS rollback (Roaming Retry) flow process, its basic thought is exactly when user's page response is received by mobile switching centre 2, if there is not user's contextual information, then initiate the paging refuse information to the user, UE initiates more new technological process of position to mobile switching centre 2 immediately again, thereby trigger again to the business of mobile switching centre 2 and set up process, describing about the detailed process of Roaming Retry can be with reference to 3GPP agreement TS 23.018.This scheme has solved the problem of service fail, but can cause the professional time of setting up to increase considerably.
Summary of the invention
