Abstract
A method and terminal are disclosed for use in a wireless communication system, in order for the terminal to transition from a dual mode, in which a packet switched connection and circuit switched connection are used, to a single mode in which packets are transferred. The mobile terminal is for receiving minimum system information necessary to perform this transition in an uninterrupted manner. This system information is sent to the mobile terminal automatically or on a regular basis, and is additionally sent to the mobile terminal partly upon request of the mobile terminal. A release indication is sent to the terminal separately from the system information, notifying the terminal that the circuit switched connection will be released, at which point a timer is started. The system information is employed by the mobile terminal to transition from the dual mode in the uninterrupted manner, if the timer has not expired.
