Method for TUP signaling extending No.7 signaling to realize forced interposing and forced releasing function

Abstract

The disclosed force-plug and force-release method by expanding the TUP signaling of the 7# signaling system comprises: to properly expand the IAI, ACM, and CLF message content in TUP signaling, adding Facility message unit indication calling level in IAI message, Facility message unit indication force-plug operation result, and ''reason value'' 8-bit set in CLF message. This invention bases on current hardware devices, improves business performance, and has well application future.

Description

technical field The invention relates to the technical field of network communication, in particular to a method for extending the TUP signaling of No. 7 signaling to realize the forced insertion and forced removal function. Background technique The No. 7 signaling system is a mature and reliable inter-office signaling system, which is widely used in telecommunications networks, mobile networks, intelligent networks and other fields. In addition to public networks, it has also been widely used in some private networks in recent years. TUP (Telephone User Part, telephone user part) signaling is a part of the No. 7 signaling system and is used to support common voice services. Its message structure is simple, and it cannot support the increasing number of non-voice services and some supplementary services, such as inter-office forced insertion and forced removal. The inter-office forced insertion and forced release services are common services in some private networks. The ...
