ABSTRACT:
System and method for correlating multiple frames of data associated with a single call into a call record. One embodiment comprises correlating data in a radio access network by capturing data passing to and from a radio network controller, identifying ATM Adaptation Layer type 5 (AAL5) frames within the data, assigning a first call identifier to the AAL5 frames, identifying ATM Adaptation Layer type 2 (AAL2) frames within the data, assigning a second call identifier to the AAL2 frames, and combining AAL2 frames and AAL5 frames having a same first call identifier and a same second call identifier into a call record. The data passing to and from the first radio network controller may be data passing over an Iub interface between a Node B and the radio network controller or data passing over an Iur interface between two radio network controllers.
