Abstract
A method of handling service rejection for circuit switch service for a mobile device in a wireless communication system is disclosed. The method comprises receiving a service reject message with not available circuit switch service cause and a non zero timer value for a timer whose running state indicates that the mobile device is not allowed to send a extended service request message for a circuit switch service, from a network of the wireless communication system, starting the timer with the non zero timer value, and sending the extended service request message for a packet service to the network even when the timer is running.
Claims2
