Method and device for processing update failure of double-connection path

[0062] The overall processing of the present invention is as figure 1 shown.

[0063] Step 101: Obtain the path update failure type added by the secondary eNodeB, and go to step 102;

[0064] Step 102: Obtain the preset path update failure processing strategy, go to step 103;

[0065] Step 103: Process according to preset policies.

[0067] The schematic diagram of judging the failure type of the added path update of the auxiliary evolved Node B in the present invention is as follows figure 2 shown.

[0068] Step 201: Determine whether the radio access bearer modification success list is empty, if yes, go to step 202; otherwise, go to step 203.

[0069] Step 202: Verify that all modification of the radio access bearer fails.

[0070] Step 203: Determine whether the radio access bearer modification failure list is empty, if not, go to step 204.

[0071] Step 204: Confirm that the modification of the radio access bearers is partially successful, and some update fails.

[0073] The processing strategy of the partial bearer path update success of the present invention is as follows image 3 shown.

[0074] Step 301: MeNB sends SeNB modification request (SeNB modification request) to SeNB to modify failed radio access bearer (E-RAB), go to step 302.

[0075] Step 302: After receiving the modification request from the MeNB, the SeNB sends a secondary eNode modification response (SeNB modification request acknowledge) to the primary MeNB, and goes to step 303.

[0076] Step 303: If the MeNB agrees with the new configuration, the MeNB sends a radio resource control connection reconfiguration (RRC Connection Reconfiguration) message to the UE, and goes to step 304.

[0077] Step 304: UE applies the new configuration and replies with a RRC Connection Reconfiguration Complete (RRC Connection Reconfiguration Complete) message, then go to step 305.

[0078] Step 305: The MeNB sends a SeNB Reconfiguraton Complete message to the SeNB to notify the SeNB tha
