Abstract
A method of UU message transfer for fast call setup. The method includes encapsulating a Service Request into a RRC Connection Request. When a UE starts the service sensitive to call setup delay, the RRC layer encapsulates the Service Request into IDT. If this encapsulation is successful, the RRC connection request message undergoes non-critical extension, and the encapsulated IDT is disposed into the extended portion. The RNC, after receiving the extended RRC connection request, extracts the IDT message from the extended RRC CONNECTION REQUEST and sends it to the CN.
