摘要： A method for tracking, in a roaming receiver, RF channels in a multi-area system where each area has a unique RF channel and each unique RF channel has a unique address for each user. A plurality of telephone area codes are stored into a memory of the receiver with each of the telephone area codes corresponding to a different RF channel within the multi-area system. An address from the RF channel which is unique to the receiver for that specific RF channel is received by the receiver, each address corresponding to one of the stored telephone area codes. A telephone area code corresponding to the address is then retrieved from the receiver memory, and the telephone area code is displayed in a receiver display to allow a user to quickly recognize which area of the multi-area system the receiver is located within.

摘要： A method and system for routing a data packet, intended for a destination node, from a source node to a first intermediate node in a network is useful for improving network efficiency and participation. The method includes determining a priority level of the source node and a priority level of the first intermediate node (step 505). A routing path is then selected that routes the data packet from the source node to the first intermediate node based on a comparison of the priority level of the source node and the priority level of the first intermediate node (step 515). The priority level of the source node is determined in part by a number of previous data packets that were routed through the source node, and the priority level of the first intermediate node is determined in part by a number of previous data packets that were routed through the first intermediate node.

摘要： A wideband CDMA handset has a receiver that simplifies initial sequence acquisition. The receiver searches and assigns a base station carrier frequency located within a predetermined frequency band by scanning at predetermined intervals within the frequency band (38), such as every 5 MHz in a 60 MHz band. The receiver measures the received signal strength at each predetermined interval (40) and generates a received strength signal indication (RSSI) at each predetermined interval. An RSSI ratio is then calculated (42) for adjacent scanned intervals and the calculated ratios are compared (46) to a predetermined RSSI value. If one of the ratios is greater than the predetermined RSSI value, a center frequency thereof is estimated (50) and assigned as the frequency for communications with the base station.
