Radio Access Network traffic generation for Mobile Switching Center

One of the challenges faced by telecom companies is to provide robust and powerful servers that are capable to handle the great increase of the number of subscribers and to accomplish the heavy Internet-based applications that generate a tremendous traffic load. Companies evaluate their products´ performance before releasing them to the market by applying a large amount of generated traffic to the telecom servers in order to measure their capability under traffic load; powerful solutions are hence needed for generating traffic and modeling various telecom protocols. In this paper, we propose a new traffic generator solution to load the mobile switching center (MSC) for the universal mobile telecommunications system (UMTS). This traffic generator loads the MSC through various mobile call scenarios such as location update, mobile call originating, mobile call terminating, and call clearing. We utilize the UML use case model to describe the functional behaviors of the traffic generator, and present the UML analysis model that provides the logical implementation of the functional behaviors of the proposed traffic generator.
