MOBILE COMMUNICATION SYSTEM, CONTROL APPARATUS, BASE STATION, AND USER TERMINAL

摘要

A master base station comprises: a controller configured to notify a secondary base station of information for indicating whether a user plane architecture in dual connectivity is an architecture in which a SCG (Secondary Cell Group) bearer is used or an architecture in which a split bearer is used. The SCG bearer is a bearer which goes via both a serving gate way and the secondary base station without going via the master base station. The split bearer is a bearer which goes via both the serving gate way and the master base station, and which is split in a PDCP (Packet Data Convergence Protocol) layer of the master base station, and One split path of the split bearer goes via the secondary base station, and another split path of the split bearer does not goes via the secondary base station.

1. A master base station, comprising:
a controller configured to notify a secondary base station of information for indicating whether a user plane architecture in dual connectivity is an architecture in which a SCG (Secondary Cell Group) bearer is used or an architecture in which a split bearer is used, wherein the SCG bearer is a bearer which goes via both a serving gate way and the secondary base station without going via the master base station, the split bearer is a bearer which goes via both the serving gate way and the master base station, and which is split in a PDCP (Packet Data Convergence Protocol) layer of the master base station, and one split path of the split bearer goes via the secondary base station, and another split path of the split bearer does not go via the secondary base station.
