Application of a formal testing methodology to wireless telephony networks

Abstract

This paper presents the application of a formal testing methodology to protocols and services for wireless telephony networks. The methodology provides a complete and integrated coverage of all phases of the testing procedure: specification, test generation, and test execution on a given architecture. It permits to perform conformance and interoperability testing detecting different kinds of implementation faults, as for instance output and transmission faults. The test execution is performed in the framework of a set of architectures capable to deal with different environments. Telecommunication systems and mobility are the main focus of the application presented in this paper. Two case studies illustrates the application of the methodology to a wireless telephone network: conformance and interoperability testing of Wireless Application Protocol (WAP) protocols and services based on the subscriber location.

Modeling, verifying and testing the mobility management in the mobile IPv6 protocol

“…Different works regarding modeling, validation and test cases generation for mobility protocols using formal approaches were carried out [11], [12]. However, to our knowledge, there is no work dedicated to the specific case of mobility management.…”
