Cellular-telephone central call-processing system utilizing object-oriented software in adjunct personal computer for generating billing records
First Claim
1. A wireless telephone system comprising:
- a plurality of cell-sites, each cell-site having a base-station and a number of mobile-subscribers linked to said base station;
a central adjunct node-processor linking together said plurality of cell-sites, and controlling all call-processing functions and operations between said plurality of cell-sites and the public switched telephone network;
said adjunct node-processor comprising a computer having memory means for storage of data;
said memory means comprising control means for controlling call-processing of a telephone call between a said mobile-subscriber and the public switched telephone network; and
said memory means further comprising billing means for initiating the start of the billing time-period for a call associated with a said mobile-subscriber, and terminating the billing time-period upon termination of the call;
said billing relatively-instantaneously recording and tracking the billing of each said mobile-subscriber;
said billing means comprising limit constraint means for determining the need to terminate a call while the call is in progress, and termination means operatively coupled to said constraint means for terminating the call while in progress upon the determination by said constraint means of a predefined constraint for the call in progress having been violated during said call in progress.

Abstract
An adjunct processor for a wireless telephone system utilizes object-oriented software for providing a common air-interface protocol for each cell site'"'"'s base station, so that, regardless of the specific cellular system. it may be coupled to the central, adjunct node-processor of the invention, so that multifarious-operating cellular systems may be linked by the central personal computer adjunct node-processor into one holistic system comprised of many different cellular operating systems and of many node-processors. A network of many adjunct node-processors allows hand-off between adjunct processors, to that if one adjunct processor fails or is down, another adjunct processor in the network may take over its functions. Each adjunct processor also has an alarm-management system and a billing and accounts-management system, which may take over the same systems another, down adjunct processor. Each component is comprised of an objects-oriented software and a state table, with the objects-oriented software creating a pointer for the state table. The billing function is continuous during the processing of the call, so that, if the available credit for a user has expired while a call is in progress, that call is automatically terminated.

4. A method of continuously billing a call made on a wireless telephone system, said wireless telephone system comprising a plurality of cell-sites, each cell-site having a base-station and a number of mobile-subscribers linked to said base station:
- a central adjunct node-processor linking together said plurality of cell-sites, and controlling all call-processing functions and operations between said plurality of cell-sites and the public switched telephone network;
said adjunct node-processor comprising a computer having memory means for storage of data;
said memory means comprising control means for controlling call-processing of a telephone call between a said mobile-subscriber and the public switched telephone network; and
said memory means further comprising billing means for initiating the start of the billing time-period for a call associated with a said mobile-subscriber, and terminating the billing time-period upon termination of the call, said method comprising;(a) initiating said billing means of said central adjunct node-processor for start of the billing time-period for a call associated with a mobile-subscriber after the call has been connected, and terminating said billing means of said central adjunct node-processor to terminate the billing time-period upon termination of the call; (b) relatively-instantaneously recording and tracking the billing of said mobile-subscriber of said step (a) while said call is in-progress; (c) automatically terminating the mobile call while in-progress via said billing means of said central adjunct node-processor if the available credit of the user who has made the call has been used up. - View Dependent Claims (5)
