  • Wireless local loop access network system
    Patent number: 6952579
    Abstract: A wireless local loop access network system includes (a) at least one base station (13) making radio communication with a plurality of subscriber's terminals, and (b) a base station controller (14) controlling the base station (13) and connected to a public switched telephone network. The base station controller (14) includes a memory (16) for storing subscriber data therein. For instance, the memory (16) stores a first identifier used for identifying a subscriber in an interface protocol between the wireless local loop access network system and the public switched telephone network, a second identifier used for identifying a subscriber in an radio-signal interface protocol in the wireless local loop access network system, and data about correspondence between the first and second identifiers.
