Patent ID: 8050187

Claim:
A method for correlating access channels associated with a call in a UMTS Terrestrial Radio Access Network (UTRAN), comprising: detecting one or more Random Access Channel (RACH) messages; determining a User Equipment (UE) identity for each of the one or more RACH messages; storing the UE identity for the one or more RACH messages in a database; detecting a Forward Access Channel (FACH) message; determining a UE identity for the FACH message; searching the database for UE identity that was present in the RACH messages to match the UE identity that was present in the FACH message; storing information associated with the matched UE identities in a database; detecting one or more additional FACH messages, each of the additional FACH messages having the UE identity; searching the database for UE identities that match the UE identities of the additional FACH messages; and storing a number of additional pairs of matching UEs that are present in the FACH and RACH messages.
