Evaluation of Real Call Set up Success Rate in Gsm
نویسنده
چکیده
The Call Set up Success Rate is one of the most important Key performance Indicators (KPIs) used by all mobile operators. However there is no standard measurement possible for this parameter. Therefore the different operators can measure it differently. In this paper, a definition of a real Call Set up Success Rate, possibility of its implementation using the current technologies in GSM and difference between the real and implemented Call Set up Success rate is provided. The “real” in this case means that Call Set up Success Rate is calculated as ratio of the assigned TCHs to the channel requests. The error in measurement of real Call Set up Success Rate with activated Direct TCH Assignment feature is evaluated as well. The proposed error modeling can be used in order to guarantee a quality in measurement of Call Set up Success Rate.

The widespread use of wireless cellular networks has made security an ever increasing concern. GSM is the most popular wireless cellular standard, but security is an issue. The most critical weakness in the GSM protocol is the use of one-way entity authentication, i.e., only the mobile station is authenticated by the network. This creates many security problems including vulnerability against m...
