Problems solved by technology

[0005] However, as the mobile phone moves, when the mobile phone moves from the ERA area shared by two communication systems to a new RA that only belongs to one communication system, the existing method can only support the service node of this new RA and The service nodes of a communication system located in the common ERA area interact to exchange information about the mobile phone to support the mobile phone
In this way, although the mobile phone has moved out of the shared ERA area, the service node of another communication system located in the shared ERA area still cannot obtain relevant information, so it will erroneously think that the stored information of the mobile phone is still valid. resulting in a waste of system resources

[0023] In this embodiment, after the mobile phone moves from the ERA shared by the service node SGSN130 in the wireless communication system 100 and the service node MME / UPE 220 in the wireless communication system 200 to outside the ERA, the mobile phone selects the ERA in the wireless communication system 200. Service node MME / UPE 221 continues to receive services within RA261. Figure 4 A process flow diagram according to a first preferred embodiment of the present invention is described.

[0024]Step 400, the mobile phone decides to transfer to the service node MME / UPE221 in the wireless communication system 200 to continue receiving services in the RA261.

[0025] Step 401 , the mobile phone sends a routing area update request RA Update to the serving node MME / UPE 221 in the wireless communication system 200 .

[0026] Step 402 , the serving node MME / UPE221 in the wireless communication system 200 sends an MME / UPE context request message MME / UPEContext Request to the ser...

Abstract

A method is provided for managing messages when a mobile phone is switched between communication systems. The method comprises the following steps: the mobile phone updates the route to a service node of a communication system positioned outside the equivalent route region, the service node outside the equivalent route region sends a context request message to a service node of at least one communication system inside the equivalent route region, and the service node of at least one communication system inside the equivalent route region ensures the message related to the mobile phone invalid. With the inventive method, when the mobile phone is moved from the ERA region shared by two communication systems to a new RA belonging to one communication system, the service node that is positioned in the ERA region shared by two communication systems can accurately manage the related information of the mobile phone.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for managing mobile phones when they move out of an equivalent routing area (hereinafter referred to as ERA) shared by two or more communication systems. Background technique [0002] Usually, for the convenience of management, the service area of ​​a mobile communication system can be divided into several different routing areas (hereinafter referred to as RA), and each RA is managed by a service node. When a mobile phone registers with a mobile communication system, it already knows the RA it is in. As the user moves, within the mobile communication system, when the mobile phone finds that it has entered a new RA, or needs to initiate periodic RA update, etc., the mobile phone needs to perform an RA update process. During the RA update process, if the service node changes, after the information about the mobile phone is transferred to the new service node, the old se...
