WHO SHOULD ATTEND

This course is targeted at telecom professionals working on troubleshooting, quality assessment, optimisation, and OAM of UMTS/eHSPA radio interface.

Prerequisites

Participants must hold basic knowledge of UMTS/eHSPA network architecture, terminology and modes of operation. Additionally, familiarity with UMTS interfaces, protocols and signalling scenarios, so as with network monitoring tools, such as TEMS Investigation, would be helpful.

Course content

UTRAN Overview and Protocol Architecture

  • Network architecture, functions of nodes
  • Description of the layered protocol/channel architecture used in UMTS
  • Radio Network Layer/ Transport Network Layer
  • Logical/ Transport/ Physical Channels
  • HSPA specific channels

Uu-Interface (Radio Interface) Protocols

  • The protocol architecture in the UE. Detailed description of each protocol: functions, procedures, message format and coding.
  • CM/MM/SMS (NAS protocols)
  • RRC- Radio Resource Control
  • RLC- Radio Link Control
  • MAC- Medium Access Control
  • Layer 1 processing
  • HARQ for eHSPA

Iub-Interface Protocols

  • Protocols for communication between NodeB and RNC: functions and procedures of NBAP (NodeB Application Part), Iub Frame Protocols and an overview of the Iub transport network layer

Iur-Interface Protocols

  • Protocols for communication between RNCs: functions and procedures of RNSAP (Radio Network Subsystem Application Part), Iur Frame Protocols and an overview of the Iur transport network layer

Iu-Interface Protocols

  • Protocols for communication between RNC and CN: functions and procedures of RANAP (Radio Access Network Application Part), Iu Frame Protocols and an overview of the Iu transport network layer

Measurements and Mobility

  • The use of common reporting events
  • Configuration of UE measurements using System Information and the Measurement Control messageTypical mobility scenarios, including Cell Update, Soft Handover, Hard Handover, SRNS Relocation, Serving HSPA cell change

User Plane Protocols

  • PS services: functions and PDU formats of PDCP and GTP-U
  • CS services: AMR and RLP

Signalling Procedures and Hands-on Exercises

Throughout the course a number of signalling scenarios are analysed. In the hands-on exercises the participants will have the chance of self analyse log files recorded in live network, with a monitoring tool, showing both successful and failed scenarios. Case studies within this course include different signalling procedures as follows:

•    System Information Broadcast
•    RRC Connection Establishment
•    Initial Direct Transfer and Signalling Connection Establishment
•    Authentication and Key Agreement
•    Security Mode Control
•    Service Request and PDP Context Activation
•    RAB Assignment, including Radio Bearer Setup and Radio Link Setup
•    Measurement Control and Reporting
•    Soft Handover
•    Serving HSDPA cell change
•    Serving E-DCH cell change
