Problems solved by technology

[0011] It can be seen from the above-mentioned disclosed method that the disadvantage of the prior art is: after the relocation between SGSNs, the user's data transmission is interrupted due to the abnormal Iu connection, and the user must re-attach and activate to restore the connection

Embodiment Construction

[0037]The core of the present invention is that after the relocation between serving GPRS support nodes and before the completion of the routing area update, the Iu is released due to abnormal reasons, and the new serving GPRS support node (new SGSN) cannot query the user according to the grouping temporary mobile user identification of the user , and the user information (referring to the user's International Mobile Subscriber Identity) has not been obtained from the old serving GPRS support node (old SGSN); Get the user's international mobile subscriber identity in the response message; then the new service GPRS support node successfully inquires about the user according to the international mobile subscriber identity, continues to process the user's routing area update request, and feeds back the acceptance of the routing area update request to the mobile station .

[0038] The present invention will be further described below in conjunction with the accompanying drawings. ...

Abstract

The present invention relates to a routing area updating method and system after SGSN relocation. Said method includes A, MS transmitting routing area updating request to new SGSN, when new SGSN unable positioning to said user, then through marking request message requesting said user's international mobile users identification IMSI to MS; B, said MS through marking response message feeding back said IMSI to new SGSN; C, new SGSN according to said IMSI successful querying said user and obtaining resource information, then continue processing said user's routing area updating request. Said system includes user terminal, new SGSN and old SGSN, in new SGSN unable positioning said user then through marking requesting marking response to obtain said user's IMSI, and utilizing IMSI finding user terminal to make routing area updating, for solving user data transmission interruption problem due to Iu connection abnormal after completing relocation process.

Description

technical field [0001] The present invention relates to a routing area updating technology, in particular to a routing area updating method and system after relocation between Serving GPRS Supporting Nodes (SGSN, Serving GPRS Supporting Node). Background technique [0002] When the routing area where the mobile user is located changes, or the user needs to update some parameters stored in the core network, such as mobile phone capability parameters, wireless access capabilities, network capabilities, etc., the routing area update process will be initiated. If the routing area before and after the user initiates the routing area update belongs to different SGSNs, that is, under the jurisdiction of the serving GPRS support node (General Packet Radio Service: GPRS, General Packet Radio Service), the routing area update process will involve the old and new SGSNs, called Updates the routing area between SGSNs. [0003] Please refer below figure 1 , which is a flow chart of a ro...
