Abstract:
1. A bridge-based cellular Ethernet system, comprising: a Home Location Register (HLR) for managing configuration information about network entities comprising a table for storing an Internet Protocol (IP) address of a Mobile Node (MN) within a network, a Media Access Control (MAC) address of the MN, and an address of a site in which the MN is located; a plurality of Base Stations (BSs) configured for communicating with one or more MNs; a plurality of Base Station Bridges (BSBs), each BSB being connected to two or more of said plurality of Base Stations (BSs), and each BSB including a layer 2 switch; and a plurality of Site Core Bridges (SCBs), wherein each SCB is connected to one or more of the BSBs, each SCB comprising a layer 2 switch forming a core network for sending frames to other SCBs of said plurality of SCBs in a MAC-in-MAC manner, and for querying the HLR about a correspondent node with which an MN associated within a particular SCB requests communications, and for sending a frame to another SCB of said plurality of SCBs of a site in which the correspondent node is located, wherein each SCB is configured for monitoring a signal power of the MN, for determining whether the MN is to move to another SCB, for selecting a new SCB from said plurality of SCBs to which the MN is to be moved to at a predetermined subsequent time, for sending necessary path information to associated SCBs of said plurality of SCBs and the HLR for setting of the path information in the associated SCBs and the HLR nonreactively prior to criteria for performing a handover being reached, so that a reactive handover occurs between SCBs without using routers and without an IP tunneling delay to reduce handover latency, and then for commanding a handover to the MN.
