    • A system and method for paging wireless mobile devices selectively varies the effective modulation order of a paging channel to achieve improved coverage in a wireless wide area network (WWAN) cell. In one embodiment, the paging channel modulation order is selected based on a measured signal strength and/or common channel error rate. The selected modulation order is directly related to the quality of the channel environment. In another embodiment, a page message is segregated into base and extended components that are layer modulated. With layered modulation, wireless mobile devices in good coverage regions can successfully demodulate both the base and extended components to recover the entire page message. Wireless mobile devices in poor coverage regions can successfully demodulate the base component of the page message, and then request that the extended component of the page message be re- broadcast as a base component to thereby recover the entire page message.
    • 用于寻呼无线移动设备的系统和方法选择性地改变寻呼信道的有效调制阶数以在无线广域网(WWAN)小区中实现改进的覆盖。 在一个实施例中,基于测量的信号强度和/或公共信道错误率来选择寻呼信道调制阶数。 选择的调制顺序与通道环境的质量直接相关。 在另一个实施例中,页面消息被分离成被层调制的基本和扩展组件。 通过分层调制,良好覆盖区域中的无线移动设备可以成功地解调基本和扩展组件,以恢复整个页面消息。 不良覆盖区域中的无线移动设备可以成功地解调页面消息的基本组件,然后请求将页面消息的扩展组件重新广播为基础组件,从而恢复整个页面消息。

    • To improve WWAN coverage, an access node 102 broadcasts overhead messages on a first channel covering a first channel environment and a second channel covering a second channel environment within a coverage region 106. The overhead messages carry network overhead parameters for allowing wireless mobile devices 104 to acquire and maintain traffic channels within the cellular system 100. The overhead message channels are configured so that a user perceives uninterrupted wireless services while moving through different channel environments 108 in the coverage region 106. In one embodiment, the overhead message channels are separate physical channels configured with different broadcast parameters to provide coverage in different environments. In another embodiment, the overhead parameter information is segregated into base and extended components that are encoded and layer modulated onto separate logical channels. Using layered modulation, wireless mobile devices can receive base components in poor coverage regions. The base components include overhead parameters for acquiring a WWAN channel.
    • 为了改善WWAN覆盖,接入节点102在覆盖第一信道环境的第一信道和覆盖覆盖区域106内的第二信道环境的第二信道上广播开销消息。开销消息携带网络开销参数,以允许无线移动设备104 获取和维护蜂窝系统100内的业务信道。开销消息信道被配置为使得用户在移动通过覆盖区域106中的不同信道环境108时感知不间断的无线服务。在一个实施例中,开销消息信道是分离的物理信道 配置不同的广播参数,以在不同的环境中提供覆盖。 在另一个实施例中,开销参数信息被分离成基本和扩展组件,其被编码和层调制到单独的逻辑信道上。 使用分层调制,无线移动设备可以在较差的覆盖区域中接收基本组件。 基本组件包括用于获取WWAN通道的开销参数。

    • A system for updating a wireless application is provided. The system has a network service area that uses multiple networks to provide wireless coverage. An application server couples to one of the networks, and is used to communicate with local applications that operate on wireless devices within the network service area. These wireless devices also operate standard lower-level process that provide for basic connectivity and information transfer, with these lower-level process providing a network identification value. The local application monitors this network identification value, and when it changes, generates an alert that is transmitted to the application server. The alert may include information regarding the new network, therefore the application server is updated to know what network the wireless device is operating on.
    • 提供了一种用于更新无线应用的系统。 该系统具有使用多个网络提供无线覆盖的网络服务区域。 应用程序服务器连接到其中一个网络,并用于与在网络服务区内的无线设备上运行的本地应用程序进行通信。 这些无线设备还运行标准的低级过程,提供基本的连接和信息传输,这些低级过程提供网络识别价值。 本地应用程序监视此网络标识值,并在其更改时生成传送到应用程序服务器的警报。 该警报可以包括关于新网络的信息,因此应用服务器被更新以知道无线设备在哪个网络上运行。
