    • Methods and apparatus for content protection in a wireless network. A method is provided for operating a protection system to protect an application from unauthorized distribution, wherein the application will fail to operate on a device that is outside a predetermined operating region. The method includes associating a geographic identifier with the application, wherein the geographic identifier identifies the predetermined operating region, and downloading the application and the geographic identifier to the device. The method also includes receiving a request to execute the application on the device, wherein the request includes the geographic identifier, and determining a device location. The method also includes comparing the device location with the predetermined operating region identified by the geographic identifier, and preventing the application from executing when the device is outside the predetermined operating region.

    • A wireless communication device (100) includes a display (120) having a backlight (124). A backlight controller (126) selectively enables the backlight (124) to minimize power consumption and conserve energy in a battery (132). In one embodiment, a receiver (110) receives a time-of-day message from a remote location to set a timer (122) with the current time-of-day. The current time-of-day is compared with a predetermined time-of-day and the backlight controller (126) enables and disables the backlight (124) at predetermined times-of-day. The wireless communication device (100) may also include a GPS receiver (128), to determine the location of the device. The backlight controller (126) can determine the sunrise or sunset times for the specific location. The GPS data may be used in combination with the time-of-day message. A photosensor (130) can detect ambient light levels and generate an electrical signal corresponding thereto. The backlight controller (126) may use the photosensor (130) to determine ambient light levels and to enable or disable the backlight (124) based only on ambient light levels. The photosensor signal can be used in combination with the time-of-day message and/or the location data from the GPS receiver (128) to control the backlight (124).
    • 无线通信设备(100)包括具有背光(124)的显示器(120)。 背光控制器(126)选择性地使得背光(124)能够最小化电力消耗并节省电池(132)中的能量。 在一个实施例中,接收器(110)从远程位置接收日时消息以设置具有当前时间的定时器(122)。 将当前时间与预定时间进行比较,并且背光控制器(126)在预定时间点启用和禁用背光(124)。 无线通信设备(100)还可以包括GPS接收器(128),以确定设备的位置。 背光控制器(126)可以确定特定位置的日出或日落时间。 GPS数据可以与时间消息组合使用。 光传感器(130)可以检测环境光水平并产生与其对应的电信号。 背光控制器(126)可以使用光传感器(130)来确定环境光水平,并且仅基于环境光水平来启用或禁用背光(124)。 光传感器信号可以与来自GPS接收器(128)的日时消息和/或位置数据组合使用以控制背光(124)。

    • A data storage area allows a user of a wireless communication device to enter data to be processed and transmitted as a series of dual-tone multi-frequency (DTMF) tones. A wireless communication device transmits call origination over the traffic channel and can transmit DTMF tones over the traffic channel. The user may enter data into a storage area along with an indication that the entered data should be processed as DTMF tones. Data entered as DTMF tones is processed and transmitted over the traffic channel as a series of DTMF tones. A data storage area may have predetermined locations wherein data stored in the predetermined locations are processed as DTMF tones. Alternatively, a data flag or other indicator may be associated with the data to indicate processing as DTMF tones.
    • 数据存储区域允许无线通信设备的用户输入要被处理并作为一系列双音多频(DTMF)音调发送的数据。 无线通信设备通过业务信道发送呼叫发起,并可以通过业务信道发送DTMF音调。 用户可以将输入的数据作为DTMF音调处理的指示输入到存储区域中。 以DTMF音调输入的数据通过一系列DTMF音频通过业务信道进行处理和传输。 数据存储区可以具有预定位置,其中存储在预定位置的数据被处理为DTMF音调。 或者,数据标志或其他指示符可以与数据相关联,以指示作为DTMF音调的处理。
