Patent ID: 8068501

Claim:
A method for correlating data in a radio access network, comprising: capturing data passing to and from a first radio network controller (RNC); identifying ATM Adaptation Layer type 5 (AAL5) frames within the data; assigning an AAL5 call identifier to each of the AAL5 frames, the AAL5 call identifier comprising an identifier for the first RNC combined with an uplink scrambling code associated with the AAL5 frame; identifying ATM Adaptation Layer type 2 (AAL2) frames within the data; assigning an AAL2 call identifier to each of the AAL2 frames; mapping the AAL2 call identifiers to associated AAL5 call identifiers; and creating a call record for each AAL5 call identifier, each call record comprising data from frames associated with a particular AAL5 call identifier and data from frames associated with AAL2 call identifiers that are mapped to the particular AAL5 call identifier.
