Abstract
A method of improving user experience for initial IP Multimedia Subsystem (IMS) registration is proposed. When a UE boots up or leaves flight mode, the processor of the UE determines a period Tn of time for IMS PDN initial setup on a single Access-Stratum Network, starting from sending IMS PDN setup request. Upon expiration of Tn, the UE aborts the IMS PDN set up request, and performs IMS PDN set up on another Access-Stratum Network. As a result, it allows the UE to rapidly use IMS service when boots up or leaves flight mode.
