Abstract
Interoperability among telecommunications systems, possibly by different vendors, is essential for both the development of many telecommunications networks, and today's civilization development. Interoperability testing is very costly, as it has a complexity of (n**2) for n systems, and somewhat informal. In this paper, we develop a 'Conformance Testing (CT)'-based formal technique to determine interoperability requirements/guarantees. It allows automated derivation of the interoperability' requirements of various networks as well as the interoperability guarantees among different telecommunications systems. This is achieved using static analysis of the conformance classes of the standard and knowledge of the implementation's degree of conformance (DoC) of the telecommunications systems. Consequently, it results in a lot of cost saving in addition to being a formal technique.
Highlights
Different telecommunications networks are typically by different vendors
We develop a Conformance Testing (CT)-based method for interoperability analysis and guarantees
CT is the type of testing that aims at increasing the confidence in the correct implementation of the telecommunications products
Summary
Different telecommunications networks are typically by different vendors This is often associated with many interoperability problems. Different telecommunications products by the same vendor and that play different roles in the network may have interoperability problems in certain cases. Building a multi-vendor network has become a key requirement of every intelligent telecommunications user This is to relief that user from dependency on any single telecommunications vendor. Such independence, when achieved, results in better economics of the network expansion and more importantly a feature richer network and continuous supply of telecommunications products. This motivated the work on Interoperability Testing.
