Title:
無線局、無線端末、通信システム、及び制御方法
Document Type and Number:
Japanese Patent JP6512345
Kind Code:
B2
Abstract:
A radio communication system includes a radio access network (1) and a radio terminal (2). The radio access network (1) includes a first base station (11) that manages a first cell (110) and a second base station (12) that manages a second cell (120). The radio terminal (2) supports dual connectivity involving a bearer split in which a network bearer between the radio terminal (2) and a core network (3) is split over the first base station (11) and the second base station (12). The radio access network (1) is configured to transmit, to the radio terminal (2), first control information that relates to an access stratum and is necessary for the dual connectivity involving the bearer split. It is thus possible to provide, for example, a control procedure or signalling necessary for starting dual connectivity involving a bearer split.
