ABSTRACT:
A method and apparatus for providing a cellular zone is disclosed. A communication link connects a cellular base station and a wireless access point. A typical communication link can be a wire-based communication network, such as the Internet, using IP telephony protocol. The wireless access point communicates with a cell phone over a cellular frequency and thereby establishes the cellular zone. Where the area of the cellular zone and the coverage area of the cellular base station overlap, continuous arbitration is performed to select a communications channel. The strength of a first signal received from the cellular base station is compared to the strength of a second signal received from the wireless access point. Selection criteria include signal strength and a time-oriented criteria to maintain continuity of communication channel.
