NGN, SIGTRAN and IP-Based Signalling Transport in UMTS

Course Description

Introduction of IP transport networks into mobile and fixed telecommunications requires that user traffic as well as the signalling adopt to the IP technology. The upgrade towards an IP transport infrastructure does not require simultanuous migration of user traffic and signalling. It is rather common that signalling moves onto an IP transport first.

In order to provide seemless migration and full backwards compatibility with existing SS7 based signalling infrastructure, the migration requires some adaptation mechanisms and new protocols. The standards that specify these mechanisms and protocols are called SIGTRAN and are globally implemented.

The main driver for the choice of SIGRTAN/IP is to benefit from a common transport technology, while being compatible with legacy SS7 implementations.

This course provides the student with knowledge of SIGTRAN architec¬tures as well as a background in next generation telephony architectures. The focus of the course is the SIGTRAN protocols that enable C7/SS7 protocols to be run over IP transport networks: namely the SCTP, M2UA, M2PA, M3UA, IUA, and SUA protocols.

In addition, an overview of Next Generation Network architecture is given and the applicable protocols like BICC, H.248 and SIP are explained.
