  • Patent number: 8694001
    Abstract: System and method for obtaining identity number of user equipment in an LTE system. An identity number of a user equipment may be obtained at an eNodeB in an LTE network having an MME. In order to obtain the identity number, the eNodeB may receive a first message from the user equipment and extract a first part of an identity number of the user equipment from the received first message. The eNodeB may receive a second message from the MME and extract a second part of the identity number of the user equipment from the second message. The eNodeB may form the identity number of user equipment by combining the extracted first part of the identity number with the extracted second part of the identity number.

  • Patent number: 8059602
    Abstract: A method for automatically optimizing a neighbor list for processing handover in an asynchronous WCDMA (Wide-band Code Division Multiple Access) network includes the steps of: collecting neighbor list data, call fault data, handover statistical data, base station location data and PSC information data of each base station sub-cell (or, sector) in a nationwide network; extracting all target sub-cells (or, sectors) available for handover by analyzing the collected data; endowing a weighting factor to the extracted target sub-cells (or, sectors) according to importance and then sorting calculated results so as to determine priorities; and subsequently inputting the target sub-cell (or, sector) information to the neighbor list according to the priorities.
