In an Inter-WLAN-System, when an UE needs to hand over to an untrusted network, e.g., M, from its serving network, e.g., N, how to choose M and the best base station under M currently is a problem yet to be completely solved, no matter whether M and N belong to the same alliance group or not and no matter whether M and N are homogeneous or heterogeneous networks. In fact, 3GPP recommended ANDSF to...
In communication networks, a cognitive network (CN) is a new type of data network which is used to solve some of the problems that face current networks. Cognitive radio (CR) is part of a cognitive network and a smart wireless communication system. CR is conscious of its surrounding environment, learns from the environment and adapts its internal states by making corresponding real-time changes in...
The aim of this study is to develop a handover algorithm based Grey Model (1, N) in Long Term Evolution (LTE) for High Speed Railway. Many methods have been proposed by researchers is used to decision in handover only based on Reference Signal Received Power (RSRP). GM (1, N) can employ in two or more input data, thus process of handover not only consider RSRP but also Reference Signal Received Quality...
