Abstract:
1. A method for dispersing user equipments (UEs) to non-preferred frequencies in a multimedia broadcast/multicast service (MBMS) system, the method comprising the steps of: receiving, by a radio network controller (RNC), information regarding a time required until a next session of an MBMS service is started from a serving GPRS support node (SGSN); determining, by a RNC, whether to set a layer dispersion indicator (LDI) in a session stop message according to the received time information; and sending, by a RNC, the session stop message to UEs, wherein the LDI is used for dispersing, to different frequencies, UEs in a preferred frequency, and wherein the LDI is set depending on whether the MBMS has the preferred frequency and whether the time required until the next session is started exceeds a threshold value.
