    • One aspect of the invention provides a system, apparatus and method that allow a wireless communication device to intelligently search for and select a communication cell based on a system identifier (SID) and network identifier (NID) order of preference rather than just pilot signal strength. Generally, a mobile device scans a frequency channel associated with the highest preferred SID/NID for pilot signals at different PN offsets. The cell associated with the strongest pilot signal detected is queried to determine whether it belongs to the SID/NID sought. If the selected PN offset belongs to a cell associated with the SID/NID sought then it is used for communications. Otherwise, the SID/NID identification process is repeated for the next strongest PN offset detected on the same frequency channel. If no pilot signals meeting these criteria are found in the frequency channel, the next highest preferred SID/NID is selected and the process is repeated.
    • 本发明的一个方面提供一种系统,装置和方法,其允许无线通信设备基于系统标识符(SID)和网络标识符(NID)优先级顺序智能地搜索和选择通信小区,而不仅仅是导频信号强度 。 通常,移动设备扫描与最高优选SID / NID相关联的频率信道用于不同PN偏移处的导频信号。 查询与检测到的最强导频信号相关联的小区,以确定它是否属于所寻求的SID / NID。 如果选择的PN偏移属于与所寻求的SID / NID相关联的小区,则它被用于通信。 否则,对同一频道上检测到的下一个最强的PN偏移重复SID / NID识别过程。 如果在频道中没有找到符合这些标准的导频信号,则选择下一个较高的优选SID / NID,并重复该过程。

    • Wireless devices with different capabilities may use a single file containing multiple (e.g., two) PRLs for system selection and acquisition. A first PRL in the file has a first (e.g., IS-683-A) format and includes PRL information for, e.g., 1x systems. A second PRL has a second (e.g., IS-683-C) format and includes PRL information for, e.g., 1x and 1xEV-DO systems or just 1xEV-DO systems. A legacy wireless device supporting only IS-683-A would read and use the first PRL for system selection and acquisition and ignore the second PRL. A wireless device supporting IS-683-C would read the second PRL and (1) use the second PRL by itself if it contains PRL information for both 1x and 1xEV-DO systems or (2) combine the first and second PRLs to generate a combined PRL if the second PRL contains PRL information for only 1xEV-DO systems.
