Abstract
In a telephone network, e.g. a cellular radio system, after a transaction at the connection management layer CM has ended, for example at the end of a telephone call, the lower layers are not automatically released. If another connection is to be set up on ending of the current call, e.g. a voice message or `Call Completion to Busy Subscriber` arrangement, a flag F is set in the connection management system CM. The status of the flag F is used to determine if the signalling connection towards a termination B should be kept or released immediately. Depending on the status of the flag F different actions are taken in the network. The connection is maintained for a predetermined interval.
