The present invention discloses a method and system for reselecting or handing over to a broadcast multicast cell. The method includes the following steps: broadcasting, by an MBMS cell, a service area identity list of a service area to which the MBMS cell belongs; determining, by a UE, whether the service area identity list includes a service area identity corresponding to a service; if the service area identity list includes service area identity corresponding to the service, setting, by the UE, a cell reselection priority of a frequency of an MBMS cell to the highest. According to the present invention, a UE can identify whether a cell capable of providing services that the UE is receiving or is interested in around the UE, so that the cell can learn which neighboring cells are MBMS cells and what services are being broadcast in MBMS cells if such MBMS cells are available.
