Abstract: The present disclosure provides a method for obtaining a UE counting result. The method includes: establishing, by the UE, a RRC connection; sending a UE counting response via the RRC connection; or, sending, by the UE, a RRC establishing message, and configuring a reason of establishing the RRC as MBMS UE counting. The present disclosure also provides a method for obtaining a UE counting result, a method and apparatus for suspending data transmission. By using the present disclosure, when the UE needs to receive the GCSE service, the MCE may obtain a correct counting result and not make wrong decision no matter whether the UE is in the RRC connected mode or in the idle mode. Therefore, the UE does not need to establish the point-to-point channel, and interruption of the data transmission and unnecessary power consumption are avoided.
