Intro to GSM mobile networks

An overview of the history, network architecture, and frequency allocations of the GSM networks. This section also describes the difference between bearer and tele-services, and continues to describe speech calls, circuit switched data services, Short Message Services (SMS), Wireless Application Protocol (WAP) and Unstructured Supplementary Service Data (USSD).

Mobility Functions

Discussed in this section are registration and related location registers (databases), SIM card functionality, location updates and roaming, location of subscribers, and charging issues associated with mobility.

The Mobile Station

This section concentrates on the operational modes and power classes of the Mobile Station (MS).

The Network Sub-system

This section describes the functions of the Mobile Switching Centre (MSC), the Visitor Location Register, the Home Location Register and the Network Management Centre.

The Base Station sub-system

Here the network elements of the BSS are described. The elements include the Base Station Controller (BSC), the Transcoder and Rate Adaptation Unit (TRAU) and the Base Transceiver Station (BTS) - both sectorised and omni configurations.

Signalling

In this section we describe the various signalling protocols employed within the GSM network including Common Channel Signalling (SS7) in the NSS, as well as LAP-D and LAP-Dm in the BSS.

Radio and Terrestrial Transmission

An overview of the transmission techniques used between the various network elements. Topics include: air interface (FDMA and TDMA) techniques as well as physical and logical channels, problems associated with the air interface and solutions such as frequency hopping, diversity etc.. Terrestrial transmission based on G703/G704 PDH is also covered.

Network Planning

A brief outline of some of the considerations to be taken into account when planning a network and increasing cell capacity.

The Future of Mobile Networks

This sections deals with the new developments in mobile networks including General Packet Radio System (GPRS), Enhanced Data Rates for GSM Evolution (EDGE), third generation systems (UMTS) and Voice over IP (VoIP).
