Abstract

Methods are disclosed for providing prepaid telephony service via an Internet protocol (IP) network system. A first method provides controlling at least one media agent or call routing station/switch of an IP network system for allowing and/or blocking call media streams from traversing through the media agent. A second method provides directing all signaling messages transmitted by a signaling agent or station and all media packets transmitting voice and data communications through at least one common device within the IP network system. The methods further provide for continuously monitoring a subscriber'"'"'s account balance and terminating the prepaid telephony service if the account balance is less than a predetermined amount

Claims

1-22. -22. (canceled)

23. A system for providing prepaid telephony service, the system comprising:

a packetized voice switch configured to determine whether a telephone number, supplied to establish a prepaid call and received via a Public Switched Telephone Network (PSTN) telephone switch, matches a prepaid access telephone number; and

a relay station coupled to the packetized voice switch, wherein the relay station is configured as a media agent to terminate the prepaid call if a match is determined.

24. A system according to claim 23, wherein the packetized voice switch is further configured to determined whether account information associated with the prepaid access telephone number is accurate, wherein the call is terminated only if the account information is accurate.

25. A system according to claim 23, wherein the packetized voice switch is further configured to monitor, during the prepaid call, an account balance associated with the prepaid access telephone number, and to interrupt the prepaid call if the account balance is less than a predetermined amount.

26. A system according to claim 25, wherein the prepaid account balance corresponds to a subscriber, the subscriber being notified about an available calling time based on the account balance prior to interrupting the prepaid call.

27. A system according to claim 23, wherein, if the telephone number does not match the prepaid access telephone number, a non-prepaid call is established by the packetized voice switch.

28. A system according to claim 23, wherein the relay station, in terminating the prepaid call, selectively blocks signaling and media packets generated by the packetized voice switch from a destination packetized voice switch.

29. A system according to claim 23, wherein the relay station, in terminating the prepaid call, communicates call media streams associated with the prepaid call to an Internet Protocol (IP) terminal.
