Abstract:
A method and apparatus for modular authentication of a wireless communication device (120) including a portable communication device (210) and a wireless communication module (220) coupleable thereto is disclosed. When the wireless communication module (220) receives information (706) from the portable communication device (210), it determines whether the information received is authentic information (710) and operates together with the portable communication device (210) as a wireless communication device (120) in a communication system (100) in response to the information received being authentic information (720). In addition, a method and apparatus is disclosed for checking subsidy lock in a wireless communication device (120) capable of operating in a communication system (100), the wireless communication device comprising a first module (210), a second module (220) and a subscriber identity module (230) coupled to the first and second modules (210, 220). The first and second modules (210, 220) independently determine whether subsidy lock information stored in the subscriber identity module (230) corresponds to correct subsidy lock information (614, 618), and set a state of the wireless communication device (120) as operable in the communication system (100) in response to determining that the subsidy lock information stored in the subscriber identity module (230) corresponds to the correct subsidy lock information (614, 618).
Abstract:
A method in a communication network entity, for example, a push-to-talk/anything server, for content sharing in a group communication session including obtaining (210) participant information from a plurality of group participants, determining (220) common group information based on the group participant information obtained, and sending (230) the common group information to the group participants, wherein the group participants format content based on the common group information before communicating content to other participants of the group session.

Abstract:
A wireless handheld communication device (102) for reducing a communication delay at a proximate wireless communication device is disclosed. The wireless handheld communication device simultaneously transmits to a remote station (106) through a base station (108), and transmits to the proximate wireless communication device (104) directly. The method includes communicating a first communication on first link (116) to a proximate wireless communication device and communicating, simultaneously with communicating the first communication, a second communication on a second link (112) to a base station, wherein the first communication and the second communication are substantially the same.
Abstract:
An apparatus and method of messaging service message control on a wireless communication device. The push-to-talk usage of a device is monitored. A push-to-talk metric is determined based on the push to talk usage of the device. A push-to-talk session unavailability mitigation is selected based on the push-to-talk metric. The session unavailability can be a delay of an activation of a push-to-talk session, an interruption of a push-to-talk session, or any other event that can adversely affect a push-to-talk session.
Abstract:
The present invention provides a method for establishing direct mobile to mobile communication between cellular mobile terminals. The method includes selecting a frequency designated as a mobile communication frequency within a cellular communication system, and transmitting a communication initiation sequence at the selected frequency by a first mobile terminal. A second mobile terminal then monitors the designated mobile communication frequencies, and detects the communication initiation sequence. In at least one embodiment, selecting a frequency includes determining the region in which the first mobile terminal is operating, and selecting a mobile communication frequency for the determined region. In at least a further embodiment, the mobile communication frequency is a mobile transmission frequency for the determined region. In at least a still further embodiment, selecting a frequency includes selecting a frequency that is designated as a mobile transmit frequency in a first supported region and is designated as a mobile receive frequency in a second supported region.

Abstract:
The present invention provides a communication controller and a method (fig. 7) for maintaining a communication connection during a cell reselection. The communication connection is maintained by changing between a first operating mode (308), such as a packet data mode, which does not support the maintenance of a communication connection throughout a cell reselection (310), and a second operating mode, such as a circuit switched mode, which does support maintenance of a communication connection during a handover. Use of a virtual mobile switching center in the base station subsystem facilitates the conversion and routing of circuit switched data, transmitted between the mobile subscriber and the base transceiver station, to the packet data network while in a circuit switched mode.
Abstract:
A wireless communication device (200) and method (300) adapted to prolong the useful life of an energy storage device is disclosed. In its simplest form, it can include: detecting (310) a first threshold of an energy conversion module comprising at least one of a temperature threshold, oxygen threshold, voltage, a current threshold, a power threshold and moisture threshold; sensing (320) a temperature in proximity to a thermal module comprising at least one of a fuel tank, an electronic computing module, and a housing; and generating (330) an air stream based on the detected first threshold (310) and the sensed temperature (320). The device (200) and method (300) can automatically and dynamically manage, for example, temperature, oxygen and/or moisture of an energy storage module, to maintain the energy storage module within desired specifications and tolerances. This can help to prolong the useful life of the energy storage module and its components and help to maintain a maximum recharging capacity.
