Method and system for a wireless subscriber to initiate a calling party number trace

摘要

A method and system for a wireless subscriber to initiate a calling party number trace includes receiving a Location Request Message at a Service Location Register for an inbound call to a subscriber, the message including Calling Party Information. If the subscriber has a Customer Originated Trace (COT) feature, the Calling Party Information is temporarily stored in a database. A Mobile Switching Center receives a feature code corresponding to a subscriber COT request and generates a Feature Request message. If it is determined that the subscriber has the COT feature and Calling Party Information temporarily stored in the database, the Calling Party Information is permanently stored for later retrieval.
