    摘要: A method and apparatus for performing adaptive null steering in a slow frequency hopping environment. Where base stations have smart beamforming antenna capability and are interconnected by a base station controller, thus accommodating cyclic and pseudo-random frequency hopping, each base station forwards information on arrival time, frequency and received power of all subscriber communications and co-channel interferers to the controller for correlation. Periodicity information relating to co-channel interferers is returned to the applicable base station, to enable the generation of a null in the direction of arrival of the interferer. Where few base stations have smart beamforming capability, frequency hopping is cyclic only, and each base station generates its own periodicity information. Base stations may also calculate direction of arrival and time of arrival information, and forward this to the controller, if applicable. The invention enhances network capabilities including a subscriber localizing capability hitherto unavailable to network operators.

    摘要: A method and apparatus for increasing capacity and performance of a base station for a sectorized cellular wireless network is disclosed in which one of the sector antennas is replaced or supplanted by a novel sub-sector antenna that generates a plurality of asymmetrical sub-sector coverage areas that collectively substantially cover the coverage area of the replaced sector antenna. The use of asymmetrical coverage areas permits the total coverage area to closely approximate the symmetrical sector coverage area without creating excessively large sub-sector handover zones or introducing severe degradation in the network performance. This in turn permits the selective replacement of a single sector antenna rather than the wholesale replacement of all sector antennas in a region, leading to lower transitional costs and the ability to provide a focused approach to capacity planning.

    摘要: A cellular location method is used in a cellular location system including a database. The cellular location method obtains radio measurements from a user terminal located in the communications network, extracts information from the obtained radio measurements, determines the location of the user terminal based on the extracted information, and stores the determined location of the user terminal and the extracted information as an entry in the database such that the determined location of the user terminal is retrieved based upon a matching score between the extracted information from the user terminal and extracted information from the specified user terminal. Additionally, when the determined location of the user terminal is retrieved based upon the matching score, the location of the specified user terminal is determined to be the determined location of the user terminal.

    摘要: A method, program, system and apparatus perform dynamic load balancing of coverage areas in a wireless communication network. The dynamic load balancing is performed by evaluating cell congestion based on location information of subscribers in the wireless communication network, collecting network parameters related to the wireless communication network and altering network parameters based on the evaluated cell congestion. After the network parameter is altered, the coverage areas are narrowed. Improvements in cell congestion and quality of server are then determined based on the narrowing of the coverage areas. Altering of the plurality of network parameters and evaluating of the cell congestion are performed continuously until a target quality of service is achieved.
