LINKED RECORDS

摘要

A method for identifying call records for a call on a cellular communication network assigns a unique identification code for identifying the call to each call when the call is initially set up or when the call enters the network. The assigned identification code, which is unique until the call has been billed or for a predetermined period of time, is forwarded. A post processing system searches for all call records related to a call by searching for all call records which contain a certain identification code. The identification code can either remain the same through all records of a call, or be changed to allow for counting the total number of records in the call or to keep the order of the records. In addition the identification code can vary if identification codes of different records are linked in a list.
