초록 ▼

A local area network system (10) includes a wired backbone LAN (12) having a plurality of LAN segments (14, 16, 18) interconnected by transparent bridges (26, 44). A plurality of base stations (22, 52) are capable, of communicating with a mobile wireless station (30). In response to a decision at the mobile wireless station (30) to switch communication from a first base station (22) to a second base station (52) a handover request message (172) is transmitted from the mobile wireless station (30) via the backbone LAN (12) to the first base station (22) thereby updating dynamic filtering databases contained in the base stations (22, 52) and transparent bridges (26, 44) through which the handover request message (172) passes as to the new communication location of the mobile wireless station (30).

대표청구항 ▼

A method of operating a local area network system including a backbone LAN (12) having a plurality of addressable base stations (22, 52) adapted to communicate with a mobile wireless station (30), said method comprising the steps of: providing a dynamic filtering database in each one of said base stations (22, 52) identifying the location of said mobile wireless station (30) relative to the base station; deciding at said mobile wireless station (30) to hand over communications from a first base station (22) to a second base station (52); transmitting from said mobile wireless station (30) a handover request message (172) to said first base station (22) via said second base station (52) and said backbone LAN (12); updating the dynamic filtering databases in said first and second base stations (22, 52) in response to receipt of said handover request message (172); providing at least one transparent bridge (26, 44) in said backbone LAN (12), having a dynamic filtering database; forwarding said handover request message (172) via said transparent bridge (26, 44); and updating the dynamic filtering database of said transparent bridge (26, 44) in response to said handover request message (172).
