  • Patent number: 6535745
    Abstract: A method of defining a location area within the service area of a wireless network utilizes paging traffic and handoff traffic statistics. Initially, a cell having the highest volume of paging traffic is identified and marked as belonging to a working location area. The cell having the highest volume of handoff traffic with the cell in the working location area is selected and a determination is made to determine if the combined paging traffic of the first and second cells exceeds the maximum paging capacity for a location area within the service area. If the maximum paging capacity has not been exceeded, then the second cell is added to the working location area. The process continues until all cells, except for the occasional dead cell, have been allocated to a location area.

  • Patent number: 6349325
    Abstract: A telecommunications performance management system for processing, analyzing and abstracting performance data from a traffic machine (3) in real time using a hierarchial structure of a performance agents (10) connected to a user interface (11) to ensure optimum network design and performance. Each agent (10) transmits performance data to a supra agent (10) and operates according to a subscription signal and associated delivery deadline received from the supra agent (10).

  • Patent number: 6055434
    Abstract: A plurality of low powered beacons are selectively placed throughout a serving mobile telecommunications network without connecting the beacons and the telecommunications network therebetween. Each of the beacons independently transmits identification data uniquely identifying itself. An application module and a mapping table correlating each identification data with the location of the corresponding beacon are associated with the serving mobile telecommunications network. As a mobile station travels within the serving mobile telecommunications network, the mobile station receives the identification data broadcast by the closest beacon located thereto. In connection with a call connection, the mobile station then transmits the received identification data to the serving mobile telecommunications network. By determining the location of the identified beacon, the mobile telecommunications network then determines that the mobile station is located approximate thereto.

  • Patent number: 5388095
    Abstract: Individual subscriber appearances having a common directory number are identified with the existing software modules of a stored program controlled telecommunication switching system by redefining the format of the subscriber pointer data word used therein. An addition field comprising a call appearance member number is added to the subscriber pointer data to produce a subscriber call identifier data word.
