Abstract
A technique for controlling a wireless communication network to provide for blossoming capacity to a relatively high capacity state and/or wilting capacity to a relatively lower capacity state. Connections in progress with active subscriber units are properly handled without the need to send explicit handoff commands from the base stations. The cell sites may be advantageously implemented with cable microcell integrators that comprise remotely deployed transceiving equipment that are interconnected to centrally located base transceiver station equipment via a broadband cable distribution network. In an initial relatively low capacity state, adjacent cells are operated at the same carrier frequency such that they form simulcast groups so that subscriber units traveling in adjacent cells will operate with the same radio channel. As demand increases, the power level of an auxiliary radio transceiver is gradually increased while the power level of the original transceiver in the cell is gradually decreased. Once the auxiliary transceiver is operating at full power on the second channel, the mobile units in the cell will have completed their internal soft handoff processing and switch o…
