Abstract
A communications system extends over a cellular region formed of a plurality of wireless cells where each cell covers a portion of the cellular region. Each cell has a base station which is responsible for communication with the cellular subscriber. In order for a call to be properly managed in the public cellular domain, responsibility for call handling and processing must first be managed by a public MSC. Call handling with the public MSC for a private cellular subscriber first requires the exchange of information between the two systems. This is facilitated through the exchange of MAP and A interface signaling between the private and public cellular systems. Since this information on the private network is normally transmitted via IP, this information must be converted to standard SS7 based MAP and A protocol signaling in order for the public MSC to process.
