A method for analyzing a mobile radio network including the steps of collecting traffic data from call monitoring equipment connected to the mobile radio network, collecting signaling data from network monitoring equipment connected to the mobile radio network, correlating the traffic data and the signaling data related to a cell of the mobile radio network. and creating a graphical display of the correlated traffic data and the signaling data.

Apparatus and method for analyzing the quality of a cell in a mobile device network

Systems and methods for Long Term Evolution (LTE) interface correlation are described. In some embodiments, a method may include receiving a first message, the first message having been intercepted over an air (Uu) interface of an LTE network (e.g., probed via a Common Public Radio Interface (CPRI) between an Evolved-Universal Terrestrial Radio Access Network (UTRAN) Node B (eNB)'s remote radio head and baseband processing unit), the first message having a first identifier. The method may also include receiving a second message, the second message having been intercepted over the S1 interface between the eNB and a Mobility Management Entity (MME) within an Evolved Packet Core (EPC) portion of the LTE network within a given time window from the first message, the second message having a second identifier. The method may further include correlating the first and second messages in response to a match between the first and second identifiers.
