1. A method for maintaining a routing path between a selected workstation within a multisegment local area network and a mobile workstation, wherein individual segments within said multisegment local area network are each interconnected utilizing a router device and wherein selected individual segments of said multisegment local area network include a radio frequency transceiver adapted to communicate with said mobile workstation, said method comprising the steps of:

  • coupling said mobile workstation to said multisegment local area network in response to an initiation of communication between said mobile workstation and a selected radio frequency transceiver within a segment within said multisegment local area network;

    establishing a routing table only within each router device;

    automatically establishing a routing table entry which identifies a location of said mobile workstation within a routing table associated with each router device within said multisegment local area network in response to an attempted initiation of communication between said mobile workstation and a selected workstation within said multisegment local area network;

    automatically establishing a routing table entry which identifies a location of said selected workstation within a routing table associated with each router device within said multisegment local area network in response to an attempted initiation of communication between said selected workstation and said mobile workstation; and

    automatically deleting each routing table entry which identifies a location of said mobile workstation within each routing table associated with a router device within said multisegment local area network in response to a termination of communication between said mobile workstation and said selected radio frequency transceiver by transmitting an address delete request to each router device within said multisegment local area network from said selected radio frequency transceiver in response to a termination of communication between said mobile workstation and said selected radio frequency transceiver, wherein a routing path between said selected workstation and said mobile workstation may be determined from a routing table associated with each router device within said multisegment local area network without requiring the maintenance of routing path information at each workstation within a set multisegment local area network.
