ABSTRACT:
A multimedia broadcast/multicast service (MBMS) service and a method and apparatus for maintaining congestion and a signal transfer load of a cell at a suitable level when a session of the MBMS service is terminated in a frequency layer convergence (FLC) situation in which the MBMS service is provided in a preferred frequency layer (PL). When a session of the MBMS service is terminated, a radio network controller (RNC) determines if a cell selection is required in UEs, desiring to receive the MBMS service located in the PL cell, by using a start time of a new session and load levels of a current cell and other cells, and sends, to the UEs, explicit cell selection indication information along with session stop information according to a determination result. Therefore, the congestion and signal transfer load of the cell can be maintained in the suitable level.
