System and method for call tracing |
摘要 |
A system and method for tracing calls, such as those terminating in a wireless telephone system, is disclosed. The system is part of a communication network that uses a switch connected to a caller. The switch extracts information about the caller such as a calling party number and other information useful for tracing the call. Once the information has been extracted, the switch sends the information to a storage device associated with the called party, such as a home location register. The storage device creates a log of the call, storing all the extracted information. When the call is to be traced, a device capable of accessing the storage device can easily retrieve the stored information and thereby identify and locate the caller.
