Location Registration and Paging Schemes for next Generation Wireless Communication Systems a Qualifying Examination Report

This report presents a survey on location registration and paging strategies for next generation wireless systems. The location registration and paging schemes covered in this report include a thorough examination of the current research and industrial activities on location management, considering the integration of pico-cell, micro-cell, macro-cell, and satellite communication systems. In particular, the interworking function is discussed in pairs, followed by qualitative comparisons from the perspective of signaling costs. Thus, an overview of interworking between dissimilar systems which is aimed to support seamless roaming is demonstrated. In addition, paging schemes intended to reduce paging costs under delay constraints are described in detail. Furthermore, the latest eeorts on integration and optimization of location registration and paging are summarized. Finally, this report is concluded with a discussion of open problems to be solved for the next generation wireless systems.
