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
The present invention relates to the communications field, particularly, relate to a kind of method that mobile phone is managed when moving away from the common equivalent Routing Area (hereinafter to be referred as ERA) of two or more communication systems.
Background technology
Usually, for the ease of management, the coverage of a GSM can be divided into several different Routing Areas (hereinafter to be referred as RA), and each RA is managed by a service node.Mobile phone is being registered in the GSM, has just known own residing RA.Along with moving of user, within this GSM, find oneself to have got into new RA when mobile phone, when need initiate that perhaps periodic RA upgrades etc., mobile phone is RA renewal process of execution of needs just.In described RA renewal process, if variation has taken place service node, after the information transfer with relevant this mobile phone arrived new service node, old service node was with the information of removing relevant this mobile phone of being preserved.
Usually, when mobile phone moved to the coverage of another new GSM in the coverage from a GSM, the RA of these two communication systems also was different.At this moment; Mobile phone just need and new GSM in service node between carry out a RA renewal process; To also to carry out a series of processes between the service node in service node in this process in the new GSM and the old GSM; Exchange the information of relevant this mobile phone, to support moving of this mobile phone.In after changing to a new GSM, changing again, two above-mentioned processes all need be carried out once at every turn.
A kind of method that has adopted ERA is arranged now when changing GSM, can effectively reduce the execution number of times of said process.The RA that described method will be under the jurisdiction of a GSM is regarded as an ERA with a RA who is under the jurisdiction of another GSM; At mobile phone for the first time when the RA that is under the jurisdiction of a GSM moves to the RA that is under the jurisdiction of another GSM; Service node in described two GSMs exchanges the information of relevant this mobile phone each other, thereby makes the service node in two GSMs all preserve the information about this mobile phone.Like this; After this; Mobile phone is regarded as at the GSM that moves within the ERA or more renew and is equal to moving within the same RA of mobile phone at same service node, does not so just need therefore to carry out the exchange process of the information of described RA renewal process and relevant this mobile phone again.
Yet; Along with moving of mobile phone; When mobile phone moves to the new RA of of only being under the jurisdiction of a communication system from two common ERA zones of communication system; Existing method can only support the service node of the RA that this is new and the service node that is positioned at a communication system in total ERA zone to carry out alternately, and the information of relevant this mobile phone of exchange is to support moving of this mobile phone.Like this; Although mobile phone has moved out total ERA zone; Be positioned at the information that the service node of another communication system in total ERA zone but still can't obtain being correlated with; Therefore can think by error that the information of this mobile phone of being preserved is still effective, thereby cause resource waste.
Summary of the invention
Therefore; The objective of the invention is to invent a kind of when mobile phone moves to the new RA of of only being under the jurisdiction of a communication system from the common ERA zone of two or more communication systems, be positioned at the service node method of the relevant information of managing mobile phone correctly of two communication systems in total ERA zone.
For realizing above-mentioned purpose, the method for the information when a kind of managing mobile phone moves between communication system comprises step:
A) mobile phone carries out the service node of the communication system of routing update outside being positioned at equivalent Routing Area;
B) service node of at least one communication system of service node in equivalent Routing Area outside the said equivalent Routing Area sends context request message;
C) service node of the communication system in the said equivalent Routing Area makes the information of relevant said mobile phone of its preservation invalid.
According to method of the present invention; Mobile phone is when moving to the new RA of of only being under the jurisdiction of a communication system from two common ERA zones of communication system when mobile phone, the service node that is positioned at two communication systems in total ERA zone can both correctly carry out the relevant information of managing mobile phone.
