Document Type and Number:
Japanese Patent JPH10501377
Kind Code:
A
Abstract:
In a telephone network, e.g. a cellular radio system, after a transaction (e.g. a call) has ended, the connection is not fully released. If another connection is to be setup on ending of a current call, e.g. a voice message or call completion to be a 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 signal in connection towards a termination (B) should be kept or released immediately. Depending on the status of flag (F) different actions are taken in the network. The connection may be maintained for a predetermined interval. Data (F, F1, F2), concerning the status of the flags are transmitted from switching centre (MSC1) to another switching centre (MSC2) if control of the network termination is transferred. If control of the network termination (B) passes to a switching centre not capable of supporting the service to which the flag (F1) relates, the flag status is stored in a buffer register (HLR) associated with the user until such time as it is again connected to a switching centre capable of supporting the service.
