    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 (304) a level of total power received by the phone. This power level is compared (304) to a preset threshold level (C). If the power level remains below the threshold level for over two seconds (308, 312), the dual-mode or dual-band phone switches (314) 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 (402). Once in the idle state, both the pilot strength and Received Signal Strength Indication are monitored (404). If both of these levels are below respective thresholds for over eight seconds (408, 412), the phone switches (414) 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.

    Abstract translation: 一种增强双模或双频移动电话性能的方法包括：在手机最初连接到CDMA无线网络之后，监测（304）电话接收的总功率水平。 将该功率电平（304）与预设阈值电平（C）进行比较。 如果功率电平保持低于阈值电平超过两秒钟（308,312），双模式或双频带电话交换机（314）到存储在电话中的优选漫游列表检索到的AMPS或其他网络 。 如果功率电平高于阈值，则电话进入空闲状态（402）。 一旦处于空闲状态，监控导频强度和接收信号强度指示（404）。 如果这两个级别都超过八秒以上的相应阈值（408,412），则电话机切换到存储在优选漫游列表中的另一网络。 如果移动电话不是双模式或双频手机，则手机可以执行类似的测量并在与移动电话兼容的服务提供商系统之间切换。

    Abstract: A system for facilitating the acquisition of a most desirable wireless service for a wireless phone. The system includes a scanning mechanism (83) for a periodically scanning for a signal indicative of a wireless service having a coverage area that overlaps one or more coverage areas of other wireless services. A service aquisition mechanism (87) acquires the wireless service or one of the other wireless services based on predetermined selection criteria and the signal. More specifically, the present invention includes a wireless phone (26) having a first mechanism (85) for determining if a detected system, i.e., service is associated with a coverage area that overlaps one or more coverage areas of different systems. A second mechanism (84) compares the different systems to the detected system and selects a preferred system based on the comparison. A third mechanism (87) acquires the preferred system. In the specific embodiment, the wireless phone includes a computer that runs software for implementing the first, second, and third mechanisms.

    Abstract: A dynamic shared forward link channel (or “data” channel) is used to send multicast data to a group of wireless devices, e.g., using a common long code mask for the data channel. Reference power control (PC) bits are also sent on the data channel and used for signal quality estimation. A shared forward link control channel is used to send user-specific signaling to individual wireless devices, e.g., using time division multiplexing (TDM) and a unique long code mask for each wireless device. A shared forward link indicator channel is used to send reverse link (RL) PC bits to the wireless devices, e.g., using TDM. The data channel is jointly power controlled by all wireless devices receiving the data channel. The control and indicator channels are individually power controlled by each wireless device such that the signaling and RL PC bits sent on these channels for the wireless device are reliably received.

    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. The loading conditions are representative of currently available resources allocated for each of the plurality of frequencies. Each status value includes a hardware resource component, an air link resource component, and a handling resource component. Each component is indicative of respective remaining resources. The hardware resource component incorporates the number of currently available channel elements for an associated frequency. The air link resource component incorporates transmit power available for a particular frequency. The handling resource component incorporates the number of available Walsh codes for a particular frequency.

    Abstract: To mitigate re-syncs, RLP sync control frames associated with a packet data session can be sequence numbered. A single sequence number can be assigned for an entire sync procedure associated with the initiation of a packet data session. For example, the sequence number can remains the same on all sync control frames (SYNC, SYNC/ACK, ACK) of a particular packet data session. When a sync frame is received out of order within a single sequence, it can be ignored under certain conditions. For example, if a SYNC frame with a sequence number 0 is received out of order after an ACK frame with sequence number 0 is received, the mobile station can ignore the out of order SYNC frame. Thus, an RLP re-sync is avoided due to out of order RLP sync packets.
