Abstract

A mobility management method for handsets moved between two communication systems with equivalent routing area comprises steps: a handset outside of the equivalent routing area routing updates to a service node of one communication system in the equivalent routing area; the service node generates an indication; according to the indication, the service node decides to whether or not do change context with other service nodes outside of the equivalent routing area in the same communication system. Thereby, when the handset is moved from outside of the equivalent routing area to inside thereof, the necessary relative inforamtion servicing for the handset which is stored in each node outside of the equivalent routing area is transfered to each node in the equivalent routing area.

Description

Mobile phone is carried out mobility management method
Technical field
The present invention relates to the communications field, particularly, relate to a kind of carrying out mobility management method having between two communication systems of equivalent Routing Area (hereinafter to be referred as ERA) mobile phone that moves.
Background technology
Usually, for the ease of management, the coverage of a mobile communication system 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 mobile communication system, has just known own residing RA.Along with moving of user, within this mobile communication system, find oneself to have entered new RA when mobile phone, perhaps need to initiate periodic RA when upgrading, mobile phone just needs to carry out a RA renewal process.In described RA renewal process, if variation has taken place service node, after the information transfer with relevant this mobile phone arrives new service node, old service node will be removed the information of relevant this mobile phone of being preserved.
Usually, when mobile phone moved to the coverage of another new mobile communication system in the coverage from a mobile communication system, the RA of these two communication systems also was different.At this moment, mobile phone just need and new mobile communication system in service node between carry out a RA renewal process, also to carry out a series of processes between the service node in service node in this process in the new mobile communication system and the old mobile communication system, exchange the information of relevant this mobile phone, to support moving of this mobile phone.In changing again after changing to a new mobile communication system, two above-mentioned processes all need to carry out once at every turn.
A kind of method that has adopted ERA is arranged now when changing mobile communication system, can effectively reduce the execution number of times of said process.The RA that described method will be under the jurisdiction of a mobile communication system is considered as an ERA with a RA who is under the jurisdiction of another mobile communication system; At mobile phone for the first time when the RA that is under the jurisdiction of a mobile communication system moves to the RA that is under the jurisdiction of another mobile communication system, service node in described two mobile communication system exchanges the information of relevant this mobile phone each other, thereby makes service node in two mobile communication system all preserve the information about this mobile phone.Like this, after this, mobile phone is regarded as being equal to moving within the same RA of mobile phone at same service node in the mobile communication system that moves within the ERA or more renew, and 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.
In existing system, when mobile phone is registered to a mobile communication system and uses this communication system outside ERA, need a series of nodes of this system to provide service for this mobile phone, these nodes are also preserved promising this cellular service and indispensable relevant information separately.And when mobile phone moved within the ERA outside ERA, the relevant information of above-mentioned node also should get on from the node that the node outside the ERA is transferred within the ERA.And in fact, existing systems is not supported the transfer method of the relevant information that this other nodes are preserved.
Summary of the invention
Therefore, the purpose of this invention is to provide and a kind ofly have between two communication systems of ERA when mobile the method that the information relevant with mobile phone that node is preserved shifts.
For achieving the above object, a kind of to carrying out mobility management method having between two communication systems of equivalent Routing Area the mobile phone that moves, comprise step:
A) mobile phone that is positioned at outside the equivalent zone carries out the service node of routing update to a communication system that is positioned at equivalent Routing Area;
B) service node that is positioned at a communication system of equivalent Routing Area produces an indication;
C) described service node is according to described indication, decision whether with the equivalent Routing Area that is positioned at same communication system outside other service nodes carry out change context.
According to method of the present invention, mobile phone is when moving within the ERA outside ERA, and each node that also can transfer within the ERA for the indispensable relevant information of this cellular service that each node outside ERA is preserved gets on.
