  • Patent number: 6842619
    Abstract: A telecommunications system and method is disclosed for load sharing within a CDMA2000 network. The queue size of a sector (or cell) is compared with a predefined threshold. If the queue size exceeds the predefined threshold, one or more mobile terminals having their Data Rate Control (DRC) pointed towards that sector are selected to discontinue using that sector. The network transmits a message to the selected mobile terminals informing the selected mobile terminals that their DRC is no longer valid. In response, the selected mobile terminals stop pointing their DRC towards that sector, which results in an interruption of the selected mobile terminal's data sessions. To continue their data sessions, each of the selected mobile terminals may initiate a “virtual” handoff to another sector.

  • Patent number: 6597911
    Abstract: A system, method, and apparatus for performing a handover for mobile station are presented. Where a mobile station in a preexisting cellular network approaches the service area of a next generation network, the serving base station transmits a cell neighbor list to the mobile station. The cell neighbor list includes nearby base stations within the preexisting cellular network as well as the next generation network. The mobile station can then measure the signal strength on the handover measurement channels of the cells in the next generation network. A method and associated apparatus for measuring the handover measurement channels of base stations in a next generation network using Code Division Multiple Access (CDMA), are also presented.

  • Publication number: 20030016639
    Abstract: A telecommunications system and method is disclosed for delivering a Short Message Service (SMS) message to a dual mode mobile terminal in data mode within a network capable of providing both voice services and data services. To receive the SMS message during a data session, the SMS message is encapsulated into an Internet Protocol (IP) packet and routed to the mobile terminal as an electronic mail (e-mail) message. In one embodiment, when the SMS message is received at the Mobile Services Switching Center (MSC) serving the mobile terminal, the MSC determines whether the mobile terminal is in data mode. If so, the MSC converts the SMS message into an email message and routes the e-mail message to the mobile terminal via the Packet Data Service Node (PDSN) serving the mobile terminal. In an alternative embodiment, the MSC routes the SMS message to the Base Station Controller (BSC) serving the mobile terminal.

  • Patent number: 6487404
    Abstract: A system and method of detecting radio network trends in a telecommunications network. A data mining tool (52) is provided and adapted to search through the various operations and maintenance database systems belonging to one or more communications network(s) (60). The data mining tool searches through the databases to find correlations and dependencies among the parameters of the data collected and stored in the database systems. The correlations and dependencies found are then reported for further analysis which can, in turn, be used in optimization, maintenance and trouble shooting of the network.
