Communication method and system for MBMS interest indication communication
First Claim
1. A master base station device comprising:
- a transceiver circuit configured to communicate with a secondary base station device and provide control plane connectivity to a user device whilst user plane connectivity is provided to the user device by the secondary base station device;
wherein the transceiver circuit is further configured to receive a desired multimedia broadcast/multicast service, MBMS, interest indication message from the user device; and
a processor configured to determine that the MBMS service is to be provided by a cell of the secondary base station which is not currently serving the user device;
wherein the transceiver circuit is further configured to send the MBMS interest indication message to the secondary base station; and
wherein the processor is further configured to add the cell that will provide the MBMS service to a group of secondary base station cells that are currently serving the user device or for handing over the user device from a current serving cell of the secondary base station to the secondary base station cell that will provide the MBMS service.

Abstract
A system is provided in which a user device communicates control data with a first base station and communicates user data with a second base station. The user device receives, from the first base station, configuration data specific to the first base station and configuration data specific to the second base station for configuring the user device to handle in-device coexistence interference. When the user device detects interference, it identifies the base station to which the interference relates, and controls the operating of its transceiver circuitry: i) using the first base station specific configuration data if it identifies that the interference is related to the first base station; and ii) using the second base station specific configuration data if it identifies that the interference is related to the second base station.

3. A method performed by a master base station device, the method comprising:
-
providing control plane connectivity to a user device whilst user plane connectivity is provided to the user device by the secondary base station device; receiving a desired multimedia broadcast/multicast service, MBMS, interest indication message from the user device; determining that the MBMS service is to be provided by a cell of the secondary base station which is not currently serving the user device; sending the MBMS interest indication message to the secondary base station; and adding the cell that will provide the MBMS service to a group of secondary base station cells that are currently serving the user device or handing over the user device from a current serving cell of the secondary base station to the secondary base station cell that will provide the MBMS service.
