The invention relates to a method for grouping the services of called user terminal in idle state, wherein said method comprises: the first terminal builds PPP connection with PDSN; when the network receives the initial request with service type from the first terminal, based on the service request, fixing if present service type is point-to-point real-time group service; if it is and the second terminal is free, sends initial call request to the base station of second terminal, which comprises service type, the first terminal PPP relative address information and second terminal user number; the base station of second terminal receives the initial call, to build wireless service channel with the second terminal; and said base station builds A8 connection with PCF, the PCF builds A10 connection with PDSN, and the second terminal builds PPP connection with PDSN; therefore, the first and second terminals can process point-to-point bidirectional group data service. |
