Problems solved by technology

In this way, when Old SGSN and NewSGSN are products of different merchants, there may be intercommunication problems due to their different implementation methods, and the reason information for canceling relocation will still be ignored and discarded, resulting in the failure of the normal process

Embodiment Construction

[0019] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below through specific embodiments and with reference to the accompanying drawing 1 .

[0020] The present invention adds a cell used to carry the cause of relocation cancellation in the Relocation Cancel Request message sent by the Old SGSN to the New SGSN. The structure of the Relocation Cancel Request message of the present invention is as described in Table 3, wherein the increased RANAP Cause cell uses To carry the reason information for canceling the relocation, for further detailed description of this information element, refer to the description in 7.7.18 of 3GPP TS29060.

Abstract

This invention provides an information transmission method in reorientation cancellation process. The procedures are as follows a) reorientation cancellation message which includes cells that carries causal message is sent to SGSN by source RNC. b) Reorientation cancellation request message that contain burdening cancellation reorientation causal message cell is sent to SGSN that belongs to target RNC by SGSN that belongs to source RNC. Cancellation reorientation causal message that transmit from procedure a is carried on cells that burdening cancellation reorientation causal message. C) the casual message sent by b is extracted by target SGSN, and the massage is placed in connecting resource release command message and sent to target RNC. d) Target RNC releases the connecting resources after received the message, and sends back cancellation reorientation response message to source RNC through its SGSN and SGSN that belongs to source RNC. The cause of canceling reorientation can be transmitted in turn in this invention and the normal flow prescribed by standard can be finished.

Description

technical field [0001] The invention relates to the technical field of the third generation mobile communication (3G), in particular to an information transmission method in the relocation cancellation process. Background technique [0002] For the Universal Mobile Telecommunication System (UMTS, Universal Mobile Telecommunication System), when the mobile station is in the packet mobility management connection (PMM CONNECTED) state, if the mobile station switches the radio network controller (RNC) due to movement or other reasons, and the new RNC, that is, the target RNC (Target RNC) belongs to another radio network subsystem (RNS), then the mobile station needs to locate and register on the new serving GPRS node (SGSN), then it may happen that the radio network subsystem service provider (SRNS) , Serving RNS) relocation process (SRNSRelocation). During the SRNS Relocation process, if the old RNC, that is, the Source RNC (SourceRNC) expires due to a timer or other errors, i...
