A method for correlating signaling in a Long Term Evolution, LTE, network for analysis of the LTE network, the method comprising the steps of: performing, by one or more monitoring computer systems, receiving a first message associated with a user identity, the first message having been intercepted over a wireless interface of the Long Term Evolution network; extracting a first identifier from the first message; receiving a second message associated with a user identity, the second message having been intercepted over a wireline interface of the LTE network; extracting a second identifier from the second message; comparing the first and second identifiers to determine if the user identity with which the first message is associated and the user identity with which the second message is associated are the same; and associating the second message with the first message in response to the second identifier matching the first identifier when the user identity with which the first message is associated and the user identity with which the second message is associated are the same so that interface traces, signaling and equipment identifiers of the same user identity are correlated for analysis. performing, by one or more monitoring computer systems, receiving a first message associated with a user identity, the first message having been intercepted over a wireless interface of the Long Term Evolution network; extracting a first identifier from the first message; receiving a second message associated with a user identity, the second message having been intercepted over a wireline interface of the LTE network; extracting a second identifier from the second message; comparing the first and second identifiers to determine if the user identity with which the first message is associated and the user identity with which the second message is associated are the same; and associating the second message with the first message in response to the second identifier matching the first identifier when the user identity with which the first message is associated and the user identity with which the second message is associated are the same so that interface traces, signaling and equipment identifiers of the same user identity are correlated for analysis. receiving a first message associated with a user identity, the first message having been intercepted over a wireless interface of the Long Term Evolution network; extracting a first identifier from the first message; receiving a second message associated with a user identity, the second message having been intercepted over a wireline interface of the LTE network; extracting a second identifier from the second message; comparing the first and second identifiers to determine if the user identity with which the first message is associated and the user identity with which the second message is associated are the same; and associating the second message with the first message in response to the second identifier matching the first identifier when the user identity with which the first message is associated and the user identity with which the second message is associated are the same so that interface traces, signaling and equipment identifiers of the same user identity are correlated for analysis.
