  • Publication number: 20150163624
    Abstract: A method for determining mobile device location in a wireless communication network having plural base stations and at least one repeater for communicating with a mobile device is performed by a geolocation detection program for locating a mobile device. The geolocation detection program determines whether a signal received from the mobile device has passed through the at least one repeater.

  • Patent number: 8811289
    Abstract: 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.
