A method to process failing reconfiguration of wireless bearing service

Abstract

The disclosed process method when reconfiguring wireless loading business comprises: once detecting the failure before the reconfiguration coming into effect, the wireless network controller sends RB reconfiguration information and receives UE failure information before appointed time in submit information to send wireless route reconfiguration cancellation information to Note B if building or reconfiguring wireless load failure; UE cancels directly new wireless route and initiates subzone updating. This invention simplifies recovery operation greatly, reduces possibility that UE detects desynchronized RL, and ensures receiving RL failure information.

Description

technical field [0001] The present invention relates to the establishment technology of RB (Radio Bearer, radio bearer), especially a processing method when RB service reconfiguration fails. Background technique [0002] When the RNC (Radio Network Controller, radio network controller) performs RB establishment or RB reconfiguration on the UE (User Equipment, user equipment) instead of handover, the reconfiguration failure of the radio bearer service includes two situations, one is that the new configuration takes effect In the past, the RB failed to be established, and the other is that the RL lost synchronization after the new configuration took effect. [0003] In the prior art, the processing flow of RB establishment failure before the new configuration takes effect is shown in Figure 1, including the following steps: [0004] Step 1, RNC sends RL (Radio Link, wireless link) reconfiguration preparation message to NodeB, configures Node B's new code channel and time slot...

[0012] In step 5, if the UE detects that the reconfiguration (non-handover) of the service is an illegal configuration, it returns an RB establishment failure message to the network side on the original code channel. Although the Node B has not deleted the original code channel of the physical layer at this time, the RB Although the establishment failure message can be sent to RNC, but to restore the old configuration of NodeB, RNC can only delete the new configuration through the RL delete message, and then restore the old configuration through the RL establishment message, which is too complicated;
