  • Method for tracing call establishing message
    Patent number: 6473620
    Abstract: A method for tracing a call establishing message between a specific mobile station and a specific channel element or between the specific channel element and a specific vocoder in a code division multiple access mobile communication system. A base station control processor receives information of a mobile station or channel element to be traced and the type of the call establishing message to be traced, from an operator. When the specific mobile station sends a call establishing request, the processor determines whether the specific mobile station is the mobile station to be traced. The processor sends a traffic channel establishing message to the specific channel element if the specific mobile station is the mobile station to be traced. Alternatively, the processor sends the traffic channel establishing message to the specific channel element if the specific channel element is the channel element to be traced.
