During our work, the basic interoperability test sequences are generated based on the minimal-complete-coverage criterion, which removes the redundancy from conformance test sequences. Then interoperability sequences minimization problem can be considered as an instance of the set covering problem, and the GA is applied to remove redundancy in interoperability transitions. The results show that compared to conventional algorithm, the proposed algorithm is more practical to avoid the state space explosion problem, for it can reduce the length of the test sequences and maintain the same transition coverage.展开更多

These systems also demand higher data rate, higher mobility support and QoS guarantees due to rapid development of wireless and mobile networks. These requirements open potentials for the operators to increase their service portfolio and for the users to experience context-rich and personalized services. Consequently the interoperability between different wireless network platforms emerges as a crucial necessity. Here focus is given to the significance of the network interoperability aspect based on layered approach and its role in the development towards 4G. This paper also gives an overview of the major 4G features and differentiating characteristics from other generations.展开更多

However, this ongoing step is about making heterogeneous network technologies explicit and highlighting their commonalities and variabilities. It begins by studying three different cellular technologies, one from each generation (2G, 3G and 4G). After the analysis of Lte-advanced—a fourth generation technology—subject of the first paper [1], Universal Mobile Telecommunication System (UMTS) cellular network—a third generation technology—is the target of this current analysis. The final objective sought is to build Ontology capable of providing a common view of cellular network technologies.展开更多
