Study Notes
GSM Network Infrastructure
Base Transceiver Station (BTS)
- Also known as a Base Station or Cell Site
- Responsible for transmitting and receiving radio signals to/from mobile devices
- Comprises of:
- Transceivers (trx) that transmit and receive radio signals
- Antennas that amplify and direct the signals
- Power supplies and backup systems
- Can have multiple transceivers to support multiple frequencies and cells
- Typically located at the cell site, but can be co-located with other BTSs
Mobile Switching Center (MSC)
- Also known as the Mobile Telephone Exchange (MTX)
- Responsible for controlling multiple Base Station Controllers (BSCs) and connecting calls between them
- Performs:
- Handover management between cells
- Routing of calls between the PSTN and mobile networks
- Authentication and billing functions
- Acts as a gateway between the GSM network and the PSTN
- Typically located in a central location, serving a large area
Base Station Controller (BSC)
- Responsible for controlling multiple Base Transceiver Stations (BTSs)
- Performs:
- Radio resource management (e.g., channel allocation, power control)
- Handover management between BTSs
- Traffic management and congestion control
- Acts as an intermediary between the BTS and the MSC
- Typically located near the BTS sites or in a central location
Operation and Maintenance Center (OMC)
- Responsible for monitoring and controlling the GSM network
- Performs:
- Real-time monitoring of network performance and alarms
- Remote software updates and configuration management
- Fault detection and correction
- Typically located in a central location, serving the entire network
Packet Control Unit (PCU)
- Responsible for controlling packet data transmission in the GSM network
- Performs:
- Packet routing and forwarding
- Packet scheduling and prioritization
- Traffic shaping and policing
- Typically co-located with the BSC or MSC
- Enables GPRS and EDGE data services in the GSM network
GSM Network Overview
- Global System for Mobile Communications (GSM) is a 2G mobile network standard
- Uses Frequency Division Multiple Access (FDMA) and Time Division Multiple Access (TDMA) for radio resource management
- Network architecture consists of BTS, BSC, MSC, OMC, and PCU components
- Enables voice and data services, including GPRS and EDGE
