IMS Basics Training

Who Should Attend
The course is intended for those who want to extend their knowledge about mobile packet networks with basic aspects of IMS architecture, functionality and services. The detailed description of technical solutions is not included in the course.

Course Content

  1. Introduction - standardisation, horizontally and vertically integrated networks, packet bearer services in mobile networks.
  2. Network architecture - P-CSCF, S-CSCF, I-CSCF, AS, HSS, SGW, MGCF, IMS-MGW, MRFC, MRFP, BGCF, identification.
  3. QoS negotiation - establishment of connectivity for IMS control and user plane, QoS profile, PCC, QoS negotiation in GERAN, UTRAN and E-UTRAN/LTE based GPRS.
  4. Traffic cases - discovery, registration, security procedures, mobile-to-mobile call, mobile-to-PSTN call.
  5. Services - telephony, presence service, push-to-talk, immediate messaging, session based messaging, whiteboard communication, voice call continuity, single radio voice call continuity.

Course Objectives
Thanks to IP Multimedia Subsystem (IMS) mobile operators will be able to offer brand new services totally based on and built upon Internet applications and protocols. The existing services, including telephony, will be also moved to the PS domain of the mobile network. In IMS, all the teleservices, are provided end-to-end over IP connectivity provided by the cellular network, e.g. GERAN/UTRAN/E-UTRAN based GPRS or WiFi/WiMAX.
For the today 2G/3G networks IMS is an interesting but still an optional solution. For the new EPS/LTE network the IMS becomes the only method to provide teleservices to the subscribers.
The course explains IMS structure, basic signalling procedures, interactions between IMS and mobile network and the most important IMS services in the 3GPP environment.

Pre-requisites
The participants should have attended one of the following courses for better understanding:

  • GPRS Basics,
  • UMTS Basics,
  • HSDPA/HSUPA Technology,
  • EPS (LTE/SAE) Basics.

or have the equivalent knowledge on packet bearer services in 3GPP mobile networks.

Training Structure
1 day training.

Methodology
Instructor led training.
