  • Patent number: 6463283
    Abstract: A subscriber unit that supports more than one voice service option and selects the appropriate voice service option when originating and receiving a call. The subscriber unit includes a memory to store parameter values, including a first voice service option parameter value and a second voice service option parameter value. The subscriber unit also includes a means for determining whether the subscriber unit is within a home system or is roaming, and a selecting means for selecting from among at least a first voice service option corresponding to the first voice service option parameter value and a second voice service option corresponding to the second voice service option parameter value. The selecting means selects the first voice service option if the subscriber unit is within the home system, and selects the second voice service option if the subscriber is roaming.

  • Publication number: 20020137518
    Abstract: A system for improving the efficiency of a wireless communications network that employs a plurality of frequencies per cell. The system includes a first mechanism that monitors the network load associated with each of the plurality of frequencies and provides corresponding status values in response thereto. A second mechanism compares the status values to predetermined loading criteria and provides an indication in response thereto when one or more of the status values meet the criteria. A third mechanism redistributes the network load in accordance with the indication. In a specific embodiment, the criteria include one or more predetermined thresholds such that when one or more of the predetermined thresholds is surpassed by the one or more of the status values, the criteria are met. The status values are representative of loading conditions for communications system resources associated with each of the frequencies.

  • Patent number: 6363260
    Abstract: A method to enhance performance of a dual-mode or dual-band mobile phone includes, after the phone has initially connected to a CDMA wireless network, monitoring a level of total power received by the phone. This power level is compared to a preset threshold level. If the power level remains below the threshold level for over two seconds, the dual-mode or dual-band phone switches to an AMPS or other network retrieved from the preferred roaming list that is stored in the phone. If the power level is above the threshold, the phone moves into the idle state. Once in the idle state, both the pilot strength and Received Signal Strength Indication are monitored. If both of these levels are below respective thresholds for over eight seconds, the phone switches to another network stored in the preferred roaming list. If the mobile phone is not a dual-mode or dual-band phone, the mobile phone can perform similar measurements and switch between service provider systems compatible with the mobile phone.

  • Publication number: 20020012330
    Abstract: A system and method for detecting discontinuous transmission (DTX) frames. The inventive method includes the steps of receiving data transmitted in a plurality of frames; classifying each of the frames; analyzing the classification of a number of successive frames of the received data and providing a metric with respect thereto; and determining, in response to the metric, if a frame is a discontinuous frame. In the illustrative embodiment, the step of classifying includes the step of error checking the frames using a cyclic redundancy check (CRC) error checking protocol. The received frames are classified as good frames (G), erasure frames (E), or discontinuous frames (D). A numerical value is assigned to each of the frames based on the classification thereof.
