are limited in exploiting idle mode under mobile environments in which MIP is employed since they are designed without considering MIP combined with idle mode. In other words, an idle Mobile Station (MS) should perform MIP handoffs despite that it cannot receive anything while staying in idle mode, and hence, it incurs inexpedient operations. We propose a(More)
IEEE 802.16m, also known as the WirelessMAN-Advanced air interface, system adopts a random access using CDMA (Code Division Multiple Access)-based random access and message-based random access. The message-based random access is intended to reduce access delay when random access load is low. However, CDMA-based random access is used as random access load(More)
