Abstract: PROBLEM TO BE SOLVED: To provide a method of enhancing performance of a dual-mode or dual-band mobile phone.SOLUTION: After the mobile phone is initially connected to a CDMA wireless network, the level of total power received by the phone is monitored and this power level is compared to a preset threshold level. When the output level remains equal to or below the threshold level for two seconds or longer, the mobile phone switches to an AMPS or other network retrieved from the preferred roaming list that is stored in the phone. When the output level is above the threshold, the phone moves into the idle state and monitors both a pilot strength and a received signal strength indication. When both of these levels are equal to or below respective thresholds for eight seconds or longer, the mobile phone switches to another network stored in the preferred roaming list. When 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: 要解决的问题：提供一种提高双模或双频手机性能的方法。解决方案：手机初始连接到CDMA无线网络后，监控手机接收的总功率级别 并将该功率电平与预设的阈值电平进行比较。 当输出电平保持等于或低于阈值电平两秒或更长时间时，移动电话切换到从存储在电话中的优选漫游列表检索的AMPS或其他网络。 当输出电平高于阈值时，电话机进入空闲状态并同时监视导频强度和接收到的信号强度指示。 当这两个级别都等于或低于相应阈值达8秒或更长时，移动电话切换到存储在首选漫游列表中的另一个网络。 当手机不是双模式或双频手机时，手机可以进行类似的测量，并在与手机兼容的服务提供商系统之间切换。

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.

Abstract: A method and apparatus for improving searching in a remote unit of a slotted mode, wireless, communication system. In a slotted mode communication system, the remote unit is in an "active state" during its assigned slot. While in the active state, a controller in the remote unit passes selected sets of search parameters to a search engine. The integration interval of the searches performed is based on the measured signal strength of another base station. The search engine performs searches using the integration interval. Searching continues as long as the remote unit is in the active state. When the remote unit enters the inactive state, searching ceases.

Abstract: A method and apparatus for improving search efficiency in a remote unit of a slotted mode, wireless communication system. In a slotted mode communication system the remote unit is in an "active state" only during its assigned slot. A controller in the remote unit passes a selected set of search parameters to a search engine at the beginning of the assigned slot. The search engine performs a search, using the selected set of search parameters, and stores the search results. The controller then immediately passes another set of search parameters to the search engine for the next search without evaluating the results of the just completed search. Searching continues as long as the remote unit is in its assigned slot. When the remote unit enters the inactive state the controller evaluates the results of the searches performed during the active state. Evaluation of the search results provides a basis for the controller to generate new sets of search parameters to be used during the next active state of the remote unit.

Abstract: A method and apparatus for improving searching in a remote unit of a slotted mode, wireless, communication system. In a slotted mode communication system, the remote unit enters an "active state" during its assigned slot. While in the active state, a controller in the remote unit passes selected sets of search parameters to a search engine. The order that the searches are performed is based on the measured signal strength and the age of the measurement. The search engine performs searches using the selected sets of search parameters. Searching continues as long as the remote unit is in the active state. When the remote unit enters the inactive state, searching ceases. While in the inactive state, the controller evaluates the results of the searches performed during the previous active state. During the next active state, the next sequence of searching is performed based on measured signal strength and the measurement age corresponding to the measurements made during the previous active state.

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: Techniques to efficiently process paging channels in an asynchronous wireless communication system. In one aspect, if the base stations are not synchronized with each other and a remote terminal's designated page time is different from base station to base station, the remote terminal can wake up based on the earliest base station in a reacquisition search list that includes candidate base stations to which the remote terminal may be handed off. In another aspect, the criteria to select base stations for evaluation as reacquisition targets may be based on the received power of the base stations as well as their timing, both of which may be made relative to that of a preferred base station. In yet another aspect, the remote terminal may wake up multiple times in a particular paging cycle (i.e., a frame cycle or a DRX cycle) if there are one or more candidates base station to which the remote terminal may be handed off.
