ABSTRACT:
A mobile terminal and method are disclosed for use in a wireless communication system in order for the mobile terminal to be able to transition to a dual mode, in which a packet switched connection and circuit switched connection are used together, from a single mode in which packets are transferred. A packet associated control channel is used to convey a radio link control or multiple access control (RLC/MAC) message, and meanwhile packet switched resources are maintained. Then a dual transfer mode assignment message is received, as a result of using the packet associated channel to convey the radio link or multiple access control message.
