Abstract
This invention relates to a method and apparatus for offering wireless telecommunication service. Pairs of the transceivers of a wireless cell site are directly interconnected. When a request for service is received, a controller allocates a pair of the transceivers to handle the call. If the call is to the public switched telephone network, an unconnected transceiver is connected to a switching system, such as a toll switch, and a protocol converter converts between call control messages to and from the cell site and call control messages to and from the toll switch. If the cell site has directional antennas, a pair of transceivers connected to the directional antennas for serving the calling and called stations is selected; transceivers connected to an omni-directional antenna can be used for overflow traffic and for traffic between the toll office and the cell site. Advantageously, the need for switching is avoided by selecting appropriate transceiver pairs and tuning the mobile stations to the correct channels.
