Abstract

This invention presents a method for fast call setup in a mobile communication system, including the steps of radio resource control (RRC) connection setup, Non-access stratum (NAS) signaling connection setup and NAS signaling interaction, and radio access bearer (RAB) setup. User equipment (UE) sends a RRC CONNECTION REQUEST, which encapsulates NAS, to RNC. In response, the radio resource control (RNC) digests the RRC CONNECTION REQUEST and forwards NAS to the core network (CN), which sends RAB Assignment Request to RNC and starts to send the paging message to the terminal call.
