Patent ID: 7881666

Claim:
A method of controlling location information of subscribers in a wireless, ad-hoc communications network comprising a plurality of nodes, wherein at least a portion of the nodes are provided with Home Location Registers (HLRs) and each of the nodes has a Visitor Location Register (VLR) the method comprising: when an operation of a first node is to be reconfigured, transferring at least a part of records from a first HLR assigned to the first node associated with a first base transceiver station to at least one of the other nodes associated with at least one of the other base transceiver stations of the network, wherein the records from the first HLR are transferred, to the at least one of the other nodes, as a second HLR associated with the at least one of the other nodes, further wherein a second node and no HLR is assigned to the at least one of the other nodes before the transfer, and wherein the at least one of the other nodes is selected based on one of a predefined list and a selection algorithm, and wherein the selection algorithm selects at least a second node based on at least one of the factors of speed of the connection between the first and second nodes, bit error rate on the connection, bandwidth of the connection, and geographical location of the second node.
