摘要:
A mobile terminal having a plurality of communication operation modes is operated by determining a current communication operation mode of the plurality of communication operation modes of the mobile terminal, determining a current voltage of a battery that powers the mobile terminal, comparing the current voltage of the battery with a battery voltage threshold associated with the current communication operation mode, and changing the current communication operation mode to another one of the plurality of communication operation modes based on the comparison of the current voltage of the battery with the battery voltage threshold associated with the current communication operation mode.
摘要:
The position of a given mobile terminal is determined by communicating satellite positioning system information between the given mobile terminal and at least one other mobile terminal over a short-range, ad hoc wireless network, such as a Bluetooth network, to cooperatively determine the position of the given mobile terminal by the given mobile terminal and the at least one other mobile terminal that communicate over the short-range, ad hoc wireless network. Satellite positioning system information may communicated by distributing processing of the satellite positioning information, by distributing receiving of satellite positioning system information from a satellite, by communicating assistance data and/or by synchronizing timing of satellite positioning information, between the given mobile terminal and the at least one other mobile terminal over the short-range, ad hoc wireless network.
摘要:
A first transceiver in a wireless terminal receives a communication request from a first wireless network. Based on the received communication request, power is selectively provided to a second transceiver in the wireless terminal, and the second transceiver is used to establish a communication link with a second wireless terminal. The first transceiver may be a TDMA transceiver, CDMA transceiver, wireless local area network transceiver, Bluetooth transceiver, or a digital television receiver that receives the communication request from a corresponding type of network, and the second transceiver may be a different one of the receiver types that establishes a communication link with a corresponding type of network. The first transceiver may receive assistance information from the first wireless network. The assistance information may include information that can be used to establish a communication link through the second transceiver with the second wireless network.

An electronic device such as a cellular telephone, for example, includes a receiver that receives broadcast radio signals transmitted by a commercial broadcast radio station. The broadcast radio signals include information that identifies a location of the radio station, an antenna associated with the radio station, or the radio station. The device also includes positioning circuitry to allow the device to determine its current location. A controller in the device extracts the information identifying the radio station from the received broadcast signal, and acquires one or more satellites of a navigational system based on the information.

The wireless receiver of the present invention accommodates dual-carrier Evolved EDGE without significantly impacting existing receiver architectures. The inventive receiver comprises a shared local oscillator and two image-rejecting downconverters. The local oscillator generates a local oscillator frequency between two carrier frequencies of adjacent radio channels. The receiver receives a signal in each of the adjacent radio channels. In a dual-carrier mode, a first image-rejecting downconverter uses the local oscillator frequency to downconvert a first signal received in the first radio channel while rejecting a second signal received in the second radio channel. A second image-rejecting downconverter uses the local oscillator frequency to downconvert the second signal while rejecting the first signal. In a diversity mode, the first and second image-rejecting downconverters use the local oscillator frequency to downconvert the signal received in one of the radio channels while rejecting the signal received in the other radio channel.

The motive device is configured to change an orientation of the housing in response to the receipt of the signal. A method of processing receipt of a signal at a communication device is provided that includes changing an orientation of a housing of the communication device in response to the receipt of the signal using a motive device housed within the housing.
摘要:
A wireless terminal includes a multi-mode radio circuit having a plurality of different transceivers for communicating over a plurality of different wireless standards, wherein a first transceiver of the plurality of transceivers requires less power than other transceivers of the plurality of transceivers. The terminal also includes a processor and memory, and logic stored in memory and executable by the processor. The logic includes logic that selects a transceiver of the plurality of transceivers based on characteristics of a communication request, and logic that uses the first transceiver to communicate the selected transceiver to a receiving device.
