Embodiment 1
[0065] The handover control in Embodiment 1 is all completed inside the HeNB. If the access mode or CSG ID of the cell where the UE is located changes after the handover, the HeNB only needs to notify the MME to update. A specific process such as Figure 4 shown, including the following steps:
[0066] S401. The HeNB determines UEs that need to perform cell handover in the serving cell;
[0067] S402. The HeNB determines the source cell currently served by the UE that needs to perform cell handover and the handover target cell;
[0068] S403. The HeNB judges whether the source cell and the target cell are both internal cells according to the internal cell information maintained locally, and if so, continue, otherwise according to figure 2 and image 3 The flow shown is switching control;
[0069] S404, the HeNB judges whether the access modes of the two cells are the same, if they are the same, continue, otherwise go to step S408;
[0070] S405. The HeNB judges whether t...
Embodiment 2
[0088] The handover control in the second embodiment requires the participation of the MME, and the MME makes a handover decision and notifies the HeNB whether to allow the handover. A specific process such as Figure 5 shown, including the following steps:
[0089] S501. The HeNB determines UEs that need to perform cell handover in the serving cell;
[0090] S502. The HeNB determines the source cell currently served by the UE that needs to perform cell handover and the handover target cell;
[0091] S503. The HeNB judges whether the source cell and the target cell are both internal cells according to the internal cell information maintained locally, and if so, continue, otherwise according to figure 2 and image 3 The flow shown is switching control;
[0092] S504, the HeNB judges whether the access modes of the two cells are the same, if they are the same, continue, otherwise go to step S508;
[0093] S505. The HeNB judges whether the access modes of the two cells are ...
