Abstract:
1. A method of selecting a frequency layer in a connected mode user equipment (UE) on a non-preferred frequency layer (NPL) in a multimedia broadcast/multicast service (MBMS) mobile communication system, comprising the steps of: receiving from a radio network controller (RNC) a message including preferred frequency information associated with a preferred frequency layer (PL) of an MBMS service; and performing a frequency selection procedure selectively according to whether or not the preferred frequency information includes PL service restriction information, wherein the frequency selection procedure is performed for the PL of the MBMS service if the PL service restriction information is not included in the message wherein the preferred frequency information comprises the PL service restriction information, if radio resources of the PL are not sufficient to accommodate traffic of UEs that want to receive the MBMS service in a connected mode or a predetermined radio resource control (RRC) state.
