Generic signaling protocol: architecture, model, and services
Patrick A. Miller, P. N. Turcu · IEEE Transactions on Communications · 1992
The functional architecture, connection model, and services of the generic signaling protocol (GSP) are described. GSP is a simple, yet powerful, connection management protocol for ISDN. The semantics and structure of GSP support call suspension and resumption, symmetric and asymmetric bridging, third-party 'proxy' call setup, and multiple-connection multimedia calling. GSP can function as a network access, interswitch, computer-to-switch, or network configuration protocol, and it has applications in circuit-switching and packet-switching networks. An example message flow demonstrating how GSP can be used to perform third-party call setup is provided.>
