Abstract: Techniques in a wireless device for use in providing restrictions on communications via a cellular network are described. The device receives, from a private network which is external to the cellular network, an IT policy associated with an organization of the private network. The IT policy includes communication restriction information. The device also receives, over a wireless link of the cellular network, data messages via the private network. The device determines whether a communication from the device is restricted by comparing a user selected code of a communication attempt from the device with one or more codes of the communication restriction information. When the communication is determined to be restricted based on the comparing, the device disallows the communication via the cellular network. When the communication is determined to be unrestricted based on the comparing, the device allows the communication via the cellular network.

Abstract: This relates to a method for controlling illumination of a display screen on a mobile device. A light source is turned on to illuminate the display screen. An amount of information displayed on the display screen is identified. An amount of time to keep the light source turned on is determined based at least in part on the identified amount of information. The light source is kept turned on at a first intensity level for the amount of time and then turned to a second intensity level.

Abstract: Techniques in a wireless device for use in providing restrictions on communications via a cellular network are described. The wireless device communicates with a host enterprise server of a private network which is external to the cellular network for performing data synchronization in association with a personal information manager (PIM) application. The wireless device receives communication restriction information from this same host enterprise server in the private network, and stores this information in its memory. The wireless device determines whether a communication is restricted by comparing a user selected code of a communication attempt with one or more codes of the stored information. If the communication is determined to be restricted, the wireless device disallows the communication via the cellular network. If the communication is determined to not be restricted, the wireless device may allow the communication via the cellular network.

Abstract: Methods and apparatus for providing restrictions on long distance calls from wireless communication devices. The wireless devices are preferably combined voice and data communication devices. In one illustrative example, each wireless device receives and stores long distance call restriction information which is pushed from a private computer network through the wireless network. During typical operation, a wireless device determines whether call attempts from the wireless device are restricted by the long distance call restriction information. If a call attempt is restricted by the long distance call restriction information, the wireless device restricts the call attempt from the wireless device and provides for a call restriction alert indication (e.g. an alert tone or visual text). If a call attempt is not restricted by the long distance call restriction information, the wireless device allows the call attempt from the wireless device.

Abstract: A method, and device incorporating the method, permits adjustment of the on time of a light source that illuminates a display within a handheld wireless communications device. The on time may be adjusted by the amount of information to be displayed, the font size of the information, the behavioral characteristics of the end user, the type of viewing activity, and the like. An optional dim mode permits the end user to be made aware that the light illuminating the display is about to be shut off.
