METHOD AND APPARATUS FOR PROVIDING PRE-PAY AND POST-PAY COMMUNICATION SERVICES USING A SWITCHING SYSTEM TO MONITOR CALL DURATION

摘要

A method and apparatus are disclosed for providing pre-pay and post-pay calls. A switching system receives the call where the switching system is class 4 or class 5. The switching system extends the call toward an integrated service platform. The switching system then receives the call destination number and the call validation parameter. The switching system releases the call extension to the integrated service platform and extends the call using the call destination number if the call validation parameter allows the call. The switching system monitors a duration of the call and terminates the call if the duration meets or exceeds an amount indicated by the call validation parameter. One advantage for post- pay calls is the provision of post-pay calls service such as messaging and validation is centralized in the integrated service platform, which reduces the time and cost of maintaining the post-pay service.
