The PDCP layer for forwarding this side of message arrangement layer 2 starts the transmission of UE uplink and downlink data.
What if Target cell Cell2 was received be UE send re-establish request message, Target cell Cell2 is directly released
It puts data forwarding tunnel resource and continues to complete the configuration of S1 ordinary crossing.It is waited if Target cell Cell2 switches confirmation in UE
Reconfiguring for UE is not received in duration and completes message, i.e., is reached in the timing of the timer of above-mentioned waiting UE switching confirmation
When do not receive the RRC of UE transmission yet and reconfigure and complete message, data forwarding tunnel resource can also be discharged and continue to complete S1
The configuration of ordinary crossing.
Target cell Cell2 is in the data for reconfiguring completion message and source cell Cell1 transmission for receiving UE transmission
After forwarding message, start the configuration for continuing S1 ordinary crossing.
Target cell Cell2 judges whether to receive what layer 2 was sent after the response message for receiving configuration S1 ordinary crossing
Data forwarding completes instruction, if received, discharges the data forwarding tunnel resource of this side (Target cell side), and to source cell
Cell1 sends the resource release instruction information for discharging the UE related resource, is released by source cell Cell1 according to UE difference access state
Put UE related resource.If Target cell does not receive the data forwarding that layer 2 is sent and completes instruction, starts predetermined UE data and turn
It distributes into the timing of waiting time, when concrete application, can be realized by timer, open determining of waiting data forwarding to complete
When device.If Target cell Cell2 completes not receiving data forwarding completion instruction in the waiting time in predetermined UE data forwarding, i.e.,
It does not receive data forwarding yet when the timing for the timer that above-mentioned waiting data forwarding is completed reaches and completes instruction, then may be used
Directly to discharge the data forwarding tunnel resource of target side.
Target cell Cell2 notifies the S1X2 management module of layer 3 to update S1 table, modifies the accordingly new persistent district the UE
The cell ID of Cell2 and the UE in Cell2 for UE distribution are identified.
After source cell Cell1 receives the UE resource release instruction information of Cell2 transmission, shape is cut according to different UE
State executes corresponding resource release operations:
If UE incision state is that UE successfully cuts Target cell Cell2, source cell Cell1 discharges the source cell
Cell1 is other resources in addition to the network interface side resource of multiplexing of user equipment distribution；
If UE incision state reconfigures for the Target cell Cell2 RRC for not receiving UE and completes message, source cell
The RRC that Cell1 opening timing device waits UE that may send re-establishes request message；
If it is incision Target cell Cell2 failure that UE, which cuts state, such as since other exceptions cause UE that cannot succeed
Target cell Cell2 is cut, then it is all resources that user equipment (UE) distributes that source cell Cell1, which will discharge source cell Cell1,.
