Traffic Analysis and Optimization of GSM Network

Accurate traffic dimensioning plays an important role in telecommunications network planning and is particularly important for the performance analysis of mobile and wireless networks. The main goal of cellular operators now a day with the increasing number of mobile subscribers is to keep the subscribers satisfied with the delivered quality of service ( QoS ) . Traffic analysis & optimization is thus paramount importance for network planning and design. They are useful in areas such as network architecture comparisons, network resource allocations and performance evaluations. In order to achieve the best performance, service providers have to monitor and optimize their network continuously .A Operation Support Subsystem (OSS) with an online database is responsible for collection of data on live networks. In this paper, we have summarized the measurements taken on an operative GSM-900 & GSM-1800 network to evaluate and optimize traffic. Here we have established statistically the following facts (i) The peak hour in Orissa varies in four different MSC areas.(ii) Week day traffic is different from weekend traffic and the traffic intensity of weekday traffic is more than that of weekend traffic.(iii) Traffic channel availability is well within limits which implies that the network is well planned.(iv) SDCCH congestion is beyond threshold limits which implies operator is losing big revenue due to this. (v) In some cases the traffic carried exceeds the maximum full rate traffic resulting utilization of half rate TCH & thus reduction in speech quality.
