Enhancement of packet transfer mode when circuit switched resources are requested
First Claim
1. A method in a wireless communication system for a mobile terminal 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, comprising the steps of:
- using a packet associated control channel to convey a radio link control or multiple access control message, maintaining packet switched resources, and receiving a dual transfer mode assignment message as a result of using the packet associated channel to convey the radio link control or multiple access control message.

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.

15. A mobile terminal for transitioning in a wireless communication system to a dual mode wherein a packet switched connection and circuit switched connection are used together, from a single mode wherein packets are transferred, comprising:
-
a transceiver, for using a packet associated control channel that conveys a radio link control or multiple access control message; and
a processing unit, for receiving a dual transfer mode assignment message via the transceiver as a result of the radio link or multiple access control message, wherein the mobile terminal is arranged to maintain the packet switched connection while the radio link or multiple access control message is conveyed and the dual transfer mode assignment message is received. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A system for transitioning in a wireless communication system to a dual mode wherein a packet switched connection and circuit switched connection are used together, from a single mode wherein packets are transferred, comprising:
-
a mobile terminal, for processing a radio link control or multiple access control message that is conveyed by a packet associated control channel; and
a base station, for providing to the mobile terminal a dual transfer mode assignment message, as a result of using the packet associated channel to convey the radio link or multiple access control message, wherein the base station is also for providing to the mobile terminal uninterrupted packet switched resources. - View Dependent Claims (28, 29, 30)
