BASE STATION GATEWAY APPARATUS, WIRELESS COMMUNICATION SYSTEM AND COMMUNICATION METHOD |
摘要 |
A disclosed base station gateway apparatus has a C-plane processing unit and a U-plane processing unit. When a mobile station performs handover from a subordinate source base station to a subordinate target base station, the C-plane processing unit terminates S1AP signaling received from the source base station and the target base station without relaying the S1AP signaling to a mobility management apparatus. The U-plane processing unit inserts, into U-plane data that is received from a serving gateway apparatus and that is to be transferred to the source base station, an end marker indicating that the U-plane data is the last data at a predetermined timing, and switches the transfer destination of the U-plane data, received from the serving gateway apparatus, from the source base station to the target base station at a timing immediately after the end marker is inserted. |

1. A base station gateway apparatus that is connected to a mobility management apparatus, a serving gateway apparatus and subordinate base stations and that controls the subordinate base stations, the base station gateway apparatus comprising:
a C-plane processing unit; and a U-plane processing unit; wherein when a mobile station performs handover from a subordinate source base station to a subordinate target base station, said C-plane processing unit terminates S1AP signaling received from the source base station and the target base station without relaying the S1AP signaling to the mobility management apparatus; and said U-plane processing unit inserts, into U-plane data that is received from the serving gateway apparatus and that is to be transferred to the source base station, an end marker indicating that the U-plane data is the last data at a predetermined timing, and said U-plane processing unit switches a transfer destination of the U-plane data, received from the serving gateway apparatus, from the source base station to the target base station at a timing immediately after the end marker is inserted. |
