Abstract
A method of UU message transfer for fast call setup is disclosed. The method includes encapsulating a Service Request into a RRC Connection Request message. When a UE starts the service sensitive to call setup delays, the RRC Connection Request undergoes non-critical extension. The Service Request and necessary Access Stratum (AS) information are 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.
