US 2017/0325276 A1 · RADIO COMMUNICATION SYSTEM, BASE STATION, MOBILE STATION, COMMUNICATION CONTROL METHOD, AND COMPUTER READABLE MEDIUM

Abstract

A first base station (1) is configured to establish a first signaling bearer with a mobility management apparatus (5), establish a second signaling bearer with a second base station (2), and to establish a signaling radio bearer with a mobile station (3) in a first cell (10). The second base station (2) is configured to establish the second signaling bearer with the first base station (1), establish a data bearer with a data transfer apparatus (6), and to establish a data radio bearer with the mobile station (3) in a second cell (20). Furthermore, the first base station (1) is configured to transmit, to the second base station (2) through the second signaling bearer configuration information, necessary to establish the data bearer and the data radio bearer in the second base station (2). Thus, for example, bearer architecture suitable for a C/U plane split scenario is provided.

Claims22

Dependent claims

A first base station comprising:

a transmission interface configured to transmit, to a second base station, a first message for requesting the second base station to allocate radio resources for a Radio Access Bearer;
and
a reception interface configured to receive a first response for the first message, wherein
the transmission interface is further configured to transmit, to a Mobility Management Entity (MME), a second message including an address and a Tunnel Endpoint Identifier (TEID) of the second base station.
