摘要： A mobile wireless device adapts receive diversity during discontinuous reception based on downlink signal quality, page indicators and page messages. When the downlink signal quality exceeds a pre-determined threshold, the mobile wireless device decodes a page indicator channel through an initial antenna, and otherwise, decodes a paging channel through the initial antenna without decoding the page indicator channel. The mobile wireless device switches to decoding the paging channel through an alternate antenna when a page indicator decodes as an erasure. When a paging message received through a single antenna decodes with an incorrect error checking code, the mobile wireless devices enables receive diversity through multiple antennas for subsequent decoding. The mobile wireless device switches between single antenna reception and multiple antenna reception based on tracking multiple consecutive error checking code failures and successes.
摘要翻译：移动无线设备基于下行链路信号质量，页面指示符和寻呼消息来适应不连续接收期间的接收分集。当下行链路信号质量超过预定阈值时，移动无线设备通过初始天线解码页面指示符信道，否则，通过初始天线对寻呼信道进行解码，而不对页面指示符信道进行解码。当页面指示符被解码为擦除时，移动无线设备切换到通过替代天线解码寻呼信道。当通过单个天线接收的寻呼消息用不正确的错误校验码进行解码时，移动无线设备能够通过多个天线进行接收分集以进行后续解码。基于跟踪多个连续的错误检查代码故障和成功，移动无线设备在单天线接收和多天线接收之间切换。

摘要： Electronic devices may be provided that contain wireless communication circuitry. The wireless communication circuitry may include radio-frequency transceiver circuitry coupled to antennas. An electronic device may include a baseband processor and other storage and processing circuitry that implements protocol stacks for handling multiple radio access technologies. The storage and processing circuitry may use the transceiver circuitry to convey data using a first radio access technology while periodically interrupting the conveying of the data to monitor a paging channel using a second radio access technology. In performing the paging channel monitoring operations, the storage and processing circuitry may enforce a time limit that ensures that operations using the first radio access technology are not disrupted more than desired.

摘要： A single chip mobile wireless device capable of receiving and transmitting over one wireless network at a time maintains registration on two wireless communication networks that each use different communication protocols in parallel. Periodically, the mobile wireless device tunes one or more receivers from a first wireless network to a second wireless network in order to listen for paging messages addressed to the mobile wireless device from the second wireless network. The first wireless network suspends allocation of radio resources to the mobile wireless device based on receipt of a suspension message from the mobile wireless device, or based on knowledge of a paging cycle for mobile wireless device in the second wireless network, or based on detection of an out of synchronization condition with the mobile wireless device.

摘要： Methods and apparatus for synchronizing operational state during hybrid network operation. In one embodiment, the various access technologies that makeup the hybrid network not fully synchronized. Thus, a wireless device operating in a mixed mode must be capable of managing synchronization across multiple access technologies. The wireless device is configured to estimate an expected “tune-away” period when disengaging with a one access technology to address events (for example, link maintenance, calls, data, and the like) or perform monitoring on a second access technology. The estimate is then used by the device to adjust its operational parameters on the technology from which it is tuning away. This ensures smooth switching away from and back to the various network technologies.

摘要： Disclosed are methods and systems for state switching. The method is applied to a first hardware system. The first hardware system is connected with a second hardware system. The first hardware system has a first operation state and a second operation state. The second hardware system includes a memory unit. The memory unit has a first access state and a second access state. The memory unit is in the first access state currently. The method includes: the first hardware system sends an access state switching instruction to the second hardware system when the first hardware system enters the second operation state from the first operation state, wherein, the access state switching instruction is adapted to switch the memory unit of the second hardware system from the first access state to the second access state. The application of the present invention can ensure the security of key data, avoid the access of key data by malicious software, reduce the implementation costs and has a higher extensibility.
