GPRS Advanced Signalling

ELP 0408  ★★★★

The course focuses on functional aspects of the GPRS bearer service, with stress on signalling exchanged among the main GPRS entities. The GPRS signalling model is introduced and explained step by step, both in transmission and signalling planes. The various signalling protocols are discussed, with stress on the specific traffic cases (GPRS attach, PDP context activation, location updates).

The course is based on the GSM Technical Specifications and hence is vendor-independent.

Target audience – Who should attend and benefit

The course is addressed to network engineers, network planning and tuning personnel, as well as any technical stuff requiring deeper knowledge of the GPRS network.

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

An understanding of the principles of the GPRS bearer service and basic knowledge on architecture of the GPRS network is essential. Participation in GSM Advanced Signalling (ELP 0406) courses is recommended.
