Abstract: A Base Station (BS) includes an apparatus capable of performing a system reset using an Ethernet frame. The BS includes an Ethernet switch, a Programmable Logic Device (PLD), and a power unit. The Ethernet switch sorts an Ethernet frame capable of including a power reset command. The PLD attempts to detect a reset pattern at the Ethernet frame capable of including the power reset command, and determines the generation or non-generation of the power reset command depending on the detection or non-detection of the reset pattern. The power unit resets a power of a BS if the generation of the power reset command is notified from the PLD.

Abstract: A network entry method in a wireless mobile communication system is disclosed. An initial network entry method by a Mobile Station (MS) in a wireless mobile communication system includes sending a ranging request message including a Medium Access Control (MAC) address in a predetermined format to a Base Station (BS) and receiving a ranging response message including information associated with basic capability negotiation and information associated registration from the BS.

Abstract: A method is provided for performing an authentication procedure according to location registration and update for a mobile subscriber station (MSS) in a broadband wireless access (BWA) communication system. The system includes the MSS operating in idle mode to minimize power consumption, paging groups each being formed by a plurality of adjacent cells in which a plurality of MSSs are paged, base stations (BSs) for paging the plurality of MSSs within each paging group, and a server for controlling location registration and authentication for the plurality of MSSs. The server determines whether to approve a request for transition to the idle mode received from the MSS through a BS. If the server approves the request for the transition to the idle mode, it allocates authentication information to the MSS through the BS and registers location of the MSS.
