SDL Design of a Radio Resource Control Protocol for 3G Evolution Systems with Two Different Approaches

Abstract

Abstract. Despite the increasing need of formal methods, people in the industry still hesitate to use them for product development because they are not sure of success with that novel approach in their own situation. In order to encourage those people we show our experience of designing a radio resource control protocol for ETRI's 3G evolution systems in SDL with two different approaches: pure-SDL and hybrid-SDL approaches. From our design and verification results, we make an empirical evaluation of those two approaches in several aspects and suggest a simple guideline for selecting an appropriate approach according to the situation.
