Method for obtaining ue counting result, method and apparatus for suspending data transmission

Abstract

The present invention provides a method for obtaining a UE counting result. The method includes: if a UE receives a UE counting message and a service corresponding to a service identifier comprised in the UE counting message is a GCSE service transmitted via a MBMS carrier, 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 invention also provides a method for obtaining a UE counting result, a method and apparatus for suspending data transmission. By using the present invention, 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.

1 . A method for obtaining a UE counting result, comprising:
 if a User Equipment (UE) receives a UE counting request message and a service corresponding to a service identifier comprised in the UE counting request message is a Group Call System Enabler (GCSE) service transmitted via a Multimedia Broadcast and Multicast Service (MBMS) carrier,   establishing, by the UE, a Radio Resource Control (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.   
     
     
         2 . The method of  claim 1 , wherein the UE is in an idle mode. 
     
     
         3 . An apparatus, comprising: a receiving module, a sending module, a two-layer protocol module, and an application layer module, wherein:
 the application layer module is configured to, when determining that a Group Call System Enabler (GCSE) service is transmitted via a Multimedia Broadcast and Multicast Service (MBMS) carrier, instruct the two-layer protocol module to response a UE counting message;   the receiving module is configured to send a received UE counting message to the two-layer protocol module;   the two-layer protocol module is configured to at least one of:
 parse the UE counting message, generate a Radio Resource Control (RRC) establishing message according to the instruction of the application layer module, and generate a UE counting response after an RRC connection is established; or 
 parse the UE counting message, generate the RRC establishing message according to the instruction of the application layer module, and configure a reason of establishing the RRC as MBMS UE counting; and 
   the sending module is configured to send the message generated by the two-layer protocol module to over an air interface.   
     
     
         4 . An apparatus, comprising: a receiving module, a sending module, a two-layer protocol module, and an application layer module, wherein:
 the receiving module is configured to send a received UE counting message to the two-layer protocol module;   the two-layer protocol module is configured to:
 parse the UE counting message; 
 send a service identifier in the UE counting message to the application layer module; 
   the application layer module is configured to, when determining a service corresponding to the service identifier is a Group Call System Enabler (GCSE) service transmitted via a Multimedia Broadcast and Multicast Service (MBMS) carrier, instruct the two-layer protocol module to response the UE counting message;   the two-layer protocol module is further configured to at least one of:
 generate a Radio Resource Control (RRC) establishing message according to the instruction of the application layer module, and generate a UE counting response after an RRC connection is established; or 
 generate the RRC establishing message according to the instruction of the application layer module, and configure a reason of establishing the RRC as MBMS UE counting; and 
   the sending module is configured to send the message generated by the two-layer protocol module over an air interface.   
     
     
         5 . A method for obtaining a UE counting result, applied for supporting continuous transmission of a group service, comprising:
 receiving, by an evolved Node B (eNB), a UE counting request message comprising indication information that indicates counting of a number of UEs in an idle mode is required;   sending, by the eNB, the UE counting request message comprising the indication information;   receiving, by the eNB, a counting response message; and   sending, by the eNB, the counting response message.   
     
     
         6 . The method of  claim 5 , wherein
 UE counting results of User Equipments (UEs) in an RRC connected mode and an idle mode are obtained; and   the counting response message received by the eNB is sent by the UEs in the RRC connected mode and the idle mode.   
     
     
         7 . The method of  claim 5 , wherein
 UE counting results of UEs in an idle mode are obtained; and   the counting response message received by the eNB is sent by the UEs in the idle mode.   
     
     
         8 . The method of  claim 6 , wherein, for the UE in the idle mode, receiving, by the eNB, the counting response message comprises at least one of:
 receiving a UE counting response via an established Radio Resource Control (RRC) connection; or   receiving an RRC establishing message, a reason of establishing the RRC in the RRC establishing message being Multimedia Broadcast and Multicast Service (MBMS) UE counting.   
     
     
         9 . A method for suspending data transmission, applied for supporting continuous transmission of a group service, comprising:
 receiving, by an evolved Node B (eNB), a message comprising a suspend indication and a service identifier, the suspend indication and the service identifier being used to indicate that data transmission of a service corresponding to the service identifier is to be suspended;   sending, by the eNB, the message comprising the suspend indication and the service identifier;   initiating, by a UE needing to continuously receiving service data corresponding to the service identifier, a procedure of establishing a point-to-point carrier; and   stopping, by the eNB, sending the data transmission of the service at a preset time point.   
     
     
         10 . The method of  claim 9 , wherein the message further comprises time information indicating at least one of a modification period, a Single Frequency Network (SFN), or a time point from which the data transmission is suspended.
