METHOD AND APPARATUS FOR ESTABLISHING RADIO BEARER

摘要

The present invention discloses a method and an apparatus for establishing a radio bearer, and specifically to a method and an apparatus for establishing a data or signaling bearer in a radio communication system supporting multi-connectivity, wherein the method of establishing the data bearer comprises receiving information related to the data bearer, determining configuration information of respective protocol layers in a user plane protocol stack, that is established at at least one of the macro base station and the small base station for the data bearer, according to the related information and the user plane protocol stack, and sending to the user equipment a radio resource control message including the configuration information to establish the data bearer. By utilizing the method and apparatus according to the present invention, the data bearer and the signaling bearer may be efficiently established in the system supporting multi-connectivity so as to provide a user of radio communication with communication services having higher rate and throughput and enable the small base station to provide better data offloading service.
