Abstract: A method for devaluing a lost/stolen mobile device includes: receiving, by a server, a report that a mobile device is lost/stolen; suspending, by the server, a mobile identifier number associated with the mobile device, in response to the report; and transmitting, by the server, via a communication network, the suspended mobile identifier number for storage at another location. Suspending the mobile identifier number includes preventing the lost/stolen mobile device from accessing the communication network. The method includes storing the suspended mobile identifier number in an equipment identity registry database. The method further includes turning OFF Wi-Fi access, in the mobile device, in response to suspending the mobile identifier number by the server.

Abstract: A portable wireless communication device having a display screen, a light source that is capable of illuminating the display screen, and a processor coupled to the light source, dynamically adjusts a period of time during which the display screen is illuminated. The processor couples power to the light source to illuminate the display screen, determines at least one illumination time parameter associated with information to be displayed on the display screen, and maintains a coupling of power to the light source for a period of time that is based on the at least one illumination time parameter. In other embodiments of the present invention, the processor may further determine to not illuminate the display screen, or to terminate illumination of the display screen prior to expiration of the period of time, based on a received instruction or a detected level of ambient light.

Abstract: A wireless message communication system (11) delivers dynamically configurable datagram messages between a server (15) and subscriber units (17, 18, 19, 20, 21, 22). The server (15) queries a subscriber unit (17) for its data capability profile, such as supported data types, number of data fields, size of each data field, and data type for each data field. The server (15) and the subscriber unit (17) dynamically configure a message datagram (200) to conform message information in transmitted data to the data capability profile of the subscriber unit (17). The server (15) and the subscriber unit (17) then wirelessly communicate a message containing message data packets arranged and formatted according to the message datagram (200).
