Orientation.
In addition if UE does not support D é cor network at source cell, and the new cell after switching supports D é cor network, that
The step in Fig. 2 will be executed:
Step 4: when UE is redirected to D é cor network by the MME decision after switching, MME initiates GUTI again to UE
Process, wherein carrying a TAI/RAI not broadcasted.
Step 5:MME/SGSN discharges the connection of the side RAN, and UE is moved to Idle state.
Step 6: the TAI/RAI triggering UE not broadcasted initiates TAU process.MME/SGSN receives TAU/RAU request message.
Step 7:MME/SGSN process according to figure 1 initiates NAS redirection process.
But the scheme of the prior art is since it is considered that compatibility to version terminal before, cannot have shadow to the behavior of UE
It rings, so the project plan comparison finally designed is complicated.It is redirected after especially switching, process is more complicated.At present in agreement
