Abstract
A method and system for monitoring telecommunications traffic is disclosed. When a switch receives a call request, the switch sends a query message to a service controller. The service controller identifies the call request as a request to place a special service call and therefore returns to the switch a special service code, which causes the switch to route the call via a special looparound circuit to a destination. A signaling path associated with the looparound circuit passes through a designated network entity, which can therefore monitor the start and end of the call. An SCP or other network entity can then take appropriate action in response to the status of the call. The invention is particularly useful in facilitating robust account balance service such as prepaid calling.
