The beyond 3G official IEEE name for next generation of wireless technology, some people also called it as 4G (fourth-generation) mobile communication systems. Beyond 3G will be used largely to contain not only cellular telephone systems but also several types of broadband wireless access communication systems, have been attracting much interest in the mobile communication field. A new age has begun for telecommunication industry. Over the past decade wireless industry has grown at a remarkable pace, consequently level of technology development goes beyond the level of customer desire. Application flexibility and being highly dynamic will be the main features of beyond 3G services of interest to users. Being there all these emerging technologies in one cellular network has opened the work of designing and optimization of the networks to be viewed from a different perspective. APSEN analysis for Beyond 3G wireless networks has been discussed. “AP” stands for application layer, analysis of services and applications. “SE” stands for session layer, analysis of session management protocol and “N” for network layer, analysis for network protocols. The main purpose of our research is to focus on the challenges offered at APSEN for beyond 3G wireless network. There are a lot of research challenges in each of the different layers but focus will be on APSEN. The objective is to take a look at and familiarize with some of the major challenges offered at APSEN for beyond 3G wireless network. Qualitative approach has been used which will help us to collect wide range of information and enhance our knowledge by analyzing the perspectives of different researchers.
