Abstract: A wireless communication system (100) is configured to send signaling messages through a cell broadcast service (CBS). CBS message pages used to transport signaling messages are identified by assigned message identifiers. Mobile devices (114) within the communication system (100) recognize the CBS messages transporting signaling messages by the message identifiers and pass the signaling messages to an appropriate application or control program module. The message identifier may be used to specify the application or control program module to process the signaling message. The signaling messages transported by the CBS may be used in controlling a multicasting or broadcasting service. Duplicate copies of the CBS message pages may be transmitted and then buffered at the mobile device (114) as they are received until all parts of the signaling message have been received.

Abstract: The invention relates to a group application for group formation and management, in particular in a wireless environment. The present invention provides a group application in which a membership list of a group is kept updated automatically by communications between the group applications of the group. The group application handles all the complexity involved in setting up a group and maintaining a membership list for the group, without user intervention. Advantageously, the group application is implemented as a software agent. The invention also relates to an electronic device having a group application or software agent of the invention loaded therein.

Abstract: A display apparatus 200, a display controller 222, and a method for optimizing a displayed image for use in an electronic device 100 comprising a display 208 for presenting a visual image, a processor 212 for determining the intensity of a backlight 216 used for illuminating the display 208 and a controller 202 that optimizes the visual image corresponding to the intensity of the backlight 216 are described. As the intensity of the backlight 216 is reduced, the brightness of the pixels 210 is increased to compensate the image when, for example, the backlight intensity is reduced to save power. The method and apparatus are also described for compensating for uneven backlight 216 conditions.

Abstract: A method (800) and an apparatus for controlling transmission power associated with a transmitting unit (220) are described herein. The transmitting unit (220) generally includes a processing component (310), a baseband controller (320), a linearization controller (330), a variable baseband source (340), and a radio frequency (RF) component (350). The variable baseband source (340) may generate a baseband signal based on an input signal. The RF component (350) may generate an RF signal based on the baseband signal. The processing component (310) may generate a first control signal and a second control signal. Further, the processing component (310) may provide the first control signal to the baseband controller (320) to adjust the variable baseband source (340), and provide the second control signal to the linearization controller (330) to adjust the RF frequency component (350).

Abstract: An electronic device (1) provides for the selective illuminating of an associated display (5) thereby reducing battery power consumption. The electronic device (1) provides for detecting an event that will trigger an update of the display (5) and activation of illumination elements (27) for illuminating the display and determining whether the information to be displayed will occupy a region (B–L) of the display. If so, the region of the display is selectively illuminated by one or more of the illumination elements. The predetermined illumination time period may depend on a selected combination of a size of the region, a location of said region and/or a priority associated with the event.

Abstract: A portable electronic device (100) includes a vibrating transducer having a resilient support and a first mass supported by the first resilient support forming a mechanical resonator, and an electrical circuit coupled to the first vibrating transducer to apply a drive signal. A plurality of tactile vibration transducers (130, 140) can work in unison to produce strong tactile stimulus (216, 228, 230).

Abstract: A joystick that is retractable within a clam-shell style cellular telephone includes a base with a cavity and a flip hingedly attached to the base. A joystick is disposed in the cavity of the base and is moveable between an extended position and a retracted position by rotation of the flip with respect to the base.

Abstract: A method (900) and system in the form of a telephone (100) for defining and playing on the radio telephone a user defined audible alert or ring tone enables creative selection of portions of digital music files. The method (900) includes receiving (905) an incoming communication signal for communicating with a user of a radio telephone (100). Next, the method (900) provides for identifying (910) a pre-selected music file, the music file being pre-selected by the user from a plurality of music files stored on the telephone (100) to provide the audible alert in response to the receiving. The audible alert is the played (915) in which the audible alert comprises a pre-defined portion of the pre-selected music file thereby informing the user to the incoming communication signal, the portion of the music file being defined by a first stop point in the music file.

Abstract: An apparatus for acquiring a pseudo-random (PN) sequence timing for a code division multiple access (CDMA) radiotelephone. A buffer stores samples of representations of at least one pilot signal. A correlator coupled to the buffer is operable to correlate at least a portion of the samples with a PN sequence at each of a plurality of different PN offsets to produce corresponding correlation energies. A controller coupled to the correlator interrupts the correlator as soon as the PN sequence at a particular PN offset produces a correlation energy at least equal to an energy threshold.

Abstract: A method of activating a radiotelephone operable in a spread-spectrum multiple access radiotelephone system. A searcher receiver (114) is activated, and the searcher receiver (114) acquires a PN sequence timing of a pilot signal. At least one demodulation branch (122) is activated after activation of the searcher receiver (114), and the demodulation branch synchronizes to the PN sequence timing of the selected pilot signal after the searcher receiver (114) has acquired the PN sequence timing.
