Patent ID: 11695522

Abstract:
A wireless access node (e.g. a master eNB (MeNB)) is described for a wireless communication system that comprises a first wireless access network and a second wireless access network supporting a dual connectivity terminal device arranged to communicate with both the wireless access node (MeNB) on the first wireless access network and a second wireless access node (e.g. a secondary eNB (SeNB)) on the second wireless access network is provided. The wireless access node comprises a communication unit and a controller. The controller is operably coupled to the communication unit and configured to control the communication unit to transmit a first message including configuration information for a secondary cell group (SCG) to perform a certain action, to the other base station, and to receive a second message in response to the first message from the other base station, and to control the communication to transmit a third message based on the second message to the terminal, wherein the configuration information includes multimedia broadcast multicast service (MBMS) interest information.
