Abstract:
1. An analysis device, comprising: a first acquisition module for acquiring a first plurality of call setup messages and a first plurality of call tear-down messages that are i) carried over a first communication network, and ii) associated with a first communication protocol; a second acquisition module for acquiring a second plurality of call setup messages and a second plurality of call tear-down messages that are i) carried over a second communication network, and ii) associated with a second communication protocol; a processor; a memory; and a mapping element that is stored in the memory and executed by the processor, the mapping element i) respectively detecting first and second pluralities of call setup identifiers in the first and second pluralities of call setup messages, ii) respectively detecting first and second pluralities of call tear-down identifiers in the first and second pluralities of call tear-down messages, iii) correlating ones of the first call setup identifiers with ones of the first call tear-down identifiers, iv) correlating ones of the second call setup identifiers with ones of the second call tear-down identifiers, and v) mapping A) correlated ones of the first call setup identifiers and first call tear-down identifiers to B) correlated ones of the second call setup identifiers and second call tear-down identifiers, based on ones of the first call setup identifiers and second call setup identifiers being within a first delta time, and based on ones of the first call tear-down identifiers and second call tear-down identifiers being within a second delta time.
