A method of transmitting information associated with Multimedia Broadcast/Multicast Services (MBMS) between nodes, e.g. Radio Network Controllers (RNC) 15a, 15b, in a radio access network 3, e.g. UMTS Terrestrial Radio Access Network (UTRAN). A second node, e.g. serving RNC (SRNC), transmits information indicating one or more MBMS broadcast services selected by a mobile communications device, e.g. User Equipment (UE) 1c, to the first node. e.g. drift RNC (DRNC), and the first node determines which transfer mode to employ for the one or more MBMS broadcast services in dependence on this information. The invention addresses the implementation of broadcast mode services in a cellular system that allows a UE to communicate with a serving RNC (SRNC) via a drift RNC (DRNC). In particular, the invention relates to the interaction between the DRNC and the SRNC to share information indicating MBMS selected services for a UE. |
