Abstracts: The goals of this project are to study the STP and its upgraded version 8 of hiS700, which provides enhanced capability to signaling network in terms of expansion so that capacity can be increased. Signaling System 7 (SS7) is the currently used standard for the telephone signaling network. It uses common channel signaling, which is a “signaling method in which a single channel conveys, by means of labeled messages, signaling information relating to a multiplicity of circuits or calls and other information, such as that used for network management. It means that a separate network with its own nodes and links was built to provide support to the conventional voice network. SS7 is a digital packet switched network that can carry information about a number of calls over the same link simultaneously. It is responsible for connection set up, control and tear down, as well as routing and network maintenance. With SS7, signaling can take place during the conversation instead of only at the beginning. A rapid increase in the volume of SS7 traffic has led to higher demands on Signaling Transfer Point (STP) performance, specifically impacting processing delays. Today’s and the next generation networks use the Signaling System No. 7 (SS7) to exchange information within and between the networks. Engineered to provide peak performance and the highest reliability with a condensed hardware footprint, the future-proof Nokia Siemens Networks hiS 700 is the perfect solution for SS7 signaling implementations. The upgrade procedure allows for a smooth change from an ASN5 to an ASN15 based operational (live) system without service interruption, i.e. without message or counter loss. It also provides enhanced capability to signaling network in terms of expansion so that capacity can be increased.
