Network hub for interconnecting a wireless office environment with a public cellular telephone network

摘要

A network hub interconnects a public access cellular telephone network transceiving signals according to a SS7 protocol with a wireless office environment transceiving signals according to a TCP/fP protocol. The wireless office environment comprises a TCP/IP network interconnecting a plurality of private wireless networks. A processor within the hub converts received signals between being carried by the SS7 and TCP/IP protocols. The conversions are assisted by a translation table including active mobile identification numbers and IP addresses within the wireless office environment and a second table listing all signal point codes for nodes within the public access cellular telephone network.
