The method for distinguishing the MBMS service request from the other service request comprising steps of: sending a message to a UE by a RNC to indicate that the UE needs a RRC or a PS domain connection; sending a message to a SGSN by the UE to indicate it requires MBMS service or dedicated service; and sending different messages to the RNC by the SGSN according to the different service types or messages. This invention can make the SGSN correctly distinguish service requests initiated by different services and then adopt different operations on different service requests accordingly. This kind of differentiated operation can make the SGSN send different signaling to the RNC, which makes the RNC count the number of UEs accurately and avoid the waste of radio resources.
