MULTI-STANDARD PREPAID COMMUNICATION SERVICES |
摘要 |
Calls to or from a prepaid subscriber of a wireless communication network are identified as being associated with prepaid services, and a prepaid identifier is associated with the call. The prepaid identifier and other call information such as call origin or destination is routed to a prepaid services management system in another network that determines if the call is to be authorized based on, for example, a prepaid subscriber account balance stored at the prepaid services management system. The prepaid identifier can be combined with a number associated with the call origin or destination, and the combination delivered to the prepaid services management system. |
