Title: MAC Address Table Management Method In L2 Switch
Inventor: JIN YONG SEOK
IPC: H04L45/02
Filed: 2001-10-23
Abstract: PURPOSE: A method of managing an MAC address table in an L2 switch is provided to transmit an MAC control message to an inactive host by the L2 switch, and to re-register an MAC address of the inactive host on the MAC address table before aging out in response to the MAC address of the inactive host, thereby preventing an inactive host address from being deleted on the MAC address table. CONSTITUTION: An L2 switch checks an aging out time of inactive host addresses(S21), and confirms whether any inactive host address arrives at threshold time(S22). If so, the L2 switch confirms whether a packet to be transmitted to a corresponding inactive host exists(S23). If not, the L2 switch deletes an MAC address of the inactive host from the MAC address table by aging-out the MAC address, at aging-out time(S24). If the packet to be transmitted to the inactive host exists, the L2 switch creates an MAC address query message, and transmits the message to the inactive host(S25). While receiving an MAC address informing message from the inactive host, the L2 switch reads the MAC address and re-registers the read MAC address on the MAC address table(S26).

Abstract: PURPOSE: A radio resource allocation method and a base station using the same are provided to allocate a new radio resource to a link between the base station and a requesting mobile station in a cell site of the base station based on use-state information and priority information of both the base station and the neighboring base stations.

The control unit determines whether there is a non-allocated radio resource in the cell site of the base station(S2). When the non-allocated radio resource exists, the control unit detects use-state information of radio resources in the cell sites of the neighboring base stations and priority information of mobile stations using the radio resources allocated thereto by sending an inquiry to the RNC and accessing the radio resource management table of the RNC(S3). The control unit determines whether the non-allocated radio resource in the cell site of the base station is not in use in the cell sites of the neighboring base stations, based on use-state information related to the neighboring base stations(S4). When the radio resource is in use, the control unit determines whether the direction of the link data transmission related to the non-allocated radio resource in the cell site of the base station is the same as the direction of the link data transmission related to the allocated radio resource in the cell sites of the neighboring base stations(S5). When the direction of the link data transmission is the same, the interference of radio resources between the base stations or between the mobile stations is negligible. In this case, the control unit determines whether the allocation of the non-allocated radio resource in the cell site of the base station to the link between the requesting mobile station and the base station of concern is possible(S7).
