Abstract
An arrangement for prolonging voice service in an active state by forcing a double user equipment context situation. This is achieved by delaying the user equipment context release message from the source cell to the core network. When the user equipment context release message is delayed the connection with a target cell can be established before the voice service is dropped and the user does not need to redial.
