SS7 and SIGTRAN in Mobile Networks

ELP 0309  ★★★★

The introduction of horizontal architecture in telecommunication was dominated by the vision to migrate all traffic generated in a network to packet switched transport protocol. With the introduction of SIGTRAN, the same IP backbone can be used for speech, circuit switched data and GPRS as well as for signalling.
This training discusses the essential concepts and new terminologies. The SIGTRAN protocol stack and basic signalling flows are explained.

Target audience – Who should attend and benefit

The target audience for this course is Core Network engineers, service planning engineers, service design engineers and anyone who is interested to have an understand of underlying protocols in the core network nodes.

Prerequisites – What you are supposed to know prior to the course

The participants are expected to be familiar with SS7 signalling and general understanding of any telecommunication network.
