Abstract
A system is provided that provides a voice call service over a Circuit Switching (CS) domain to a User Equipment (UE) that was receiving a service in a Packet Switching (PS) domain. A Mobile Management Entity (MME) sends a paging message to the UE to provide a service in the CS domain. The MME sends a suspend request message requesting suspension of the service being provided to the UE in the PS domain, upon receiving a report message indicating that the UE has switched to the CS domain. A gateway suspends the service in the PS domain upon receiving the suspend request message from the MME.
