  • Patent number: 6094579
    Abstract: A system and method of performing presence verification for a multiple-hyperband mobile station in a candidate cell for handoff in a multiple-hyperband cellular telecommunications network. The network includes a mobile switching center (MSC) and a plurality of cells, each of which operates in one of a plurality of hyperbands. A single verification device such as a location and verification module (LVM) is installed in each cell in the cellular network, each LVM operating in the cell's allocated hyperband. When a verification request is generated, the system determines whether the candidate cell has an LVM in the hyperband in which the mobile station is operating. If not, the system determines whether the candidate cell has an overlaid cell, and whether the overlaid cell has an LVM operating in the hyperband in which the mobile station is operating. If so, the system then utilizes the LVM of the overlaid cell to verify the presence of the mobile station in the candidate cell.
