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. When the call establishing message to be traced is transmitted and received, the specific channel element sends a trace report message to the processor. Then, the processor sends the traced result of the call establishing message to a terminal of the operator. Therefore, the operator can easily recognize message transmission/reception states of the system upon call establishment, thereby enhancing a communication rate of the mobile station.
