NETWORK HUB FOR INTERCONNECTING A WIRELESS OFFICE ENVIRONMENT WITH A PUBLIC CELLULAR TELEPHONE NEWTORK

摘要

A network hub for interconnecting a first network transceiving signals according to a SS7 protocol with a second network transceiving signals according to a TCP/IP protocol is disclosed. The network hub includes means for interconnecting the hub with each of the first and second networks. A processing means 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 second network and a second table listing all signal point codes for nodes within the first network.
