Abstract: The Global System for Mobile communication (GSM) is now a worldwide-accepted standard for digital cellular systems. With the increasing of GSM popularity, customers are expecting a high level of service, from which availability is considered the major measure of quality. This paper presents a methodology for availability assessment of GSM systems. The availability block diagram model is selected to model the system, taking into account the signal strength and signal covering overlaps exist in GSM systems. The TEMS Cell Planner, TEMS Link Planner and Relex 8 are used to simulate the model for real data. The real data is collected from Korek telecom, the first GSM system in Iraqi Kurdistan. Finally recommendations are made to improve the availability within standards.
