Title:
WIRELESS COMMUNICATION SYSTEM, WIRELESS STATION, WIRELESS TERMINAL, NETWORK DEVICE, BEARER CONTROL METHOD, AND COMPUTER-READABLE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2014/054202
Kind Code:
A1
Abstract:
A wireless terminal (3) has a function in which a second wireless connection in a second cell (20) operated by a second wireless station (2) is established while a first wireless connection in a first cell (10) operated by a first wireless station (1) is being established. The first wireless station (1) sets a control bearer for forwarding a control signal related to at least the wireless terminal (3) between a higher-level network (4) and the first wireless station (1). In addition, the first wireless station (1) is configured so as to trigger a second bearer setting for forwarding user data of the wireless terminal (3) between the higher-level network (4) and the second wireless station (2). Thus, bearers can be simultaneously set for a plurality of wireless stations for one wireless terminal in order to achieve carrier aggregation of a plurality of cells operated by different wireless stations, for example.
