摘要:
A system and method in a client device (22) for controlling the power within the client device. The client device has a network access device (30, 130) and a controller (42). The network access device has at least a powered state and a power-off state. The controller provides a time period for operating the network access device in the powered state. The controller determines the time period based on a discontinuous reception parameter obtained from the network access device. The network access device determines whether wireless coverage exists for the network access device and provides an indication thereof wherein the controller switches the network access device to the power-off state if there is an out-of-coverage condition.

A communication system and method for transmitting and receiving teletype information in a vehicle (20). The communication system (22) includes an external interface (24) and a communication control unit (26). The external interface (24), embedded in the vehicle (20), is capable of receiving a first set of teletype signals from a portable TTY terminal (50) and capable of sending a second set of teletype signal to the portable TTY terminal (50). The communication control unit (26), also embedded in the vehicle (20), is connected to the external interface (24) and comprises a controller (36) and a transceiver (34). The transceiver (34) is capable of transmitting messages over a wireless communication link (A) that contain information from the first set of teletype signals. The transceiver (34) is also capable of receiving messages over the wireless communication link (A) that contain information for the second set of teletype signals.

A passenger compartment monitoring and control system provides for remote control of an undesirable condition inside a vehicle. The passenger compartment monitoring and control system includes an undesirable condition sensor disposed in the interior of the car that detects the undesirable condition. In response to a signal from the sensor, a controller contained within the vehicle and operably coupled to the sensor generates at least one control signal based on the comparison. A wireless communication device operably coupled to the controller then transmits a wireless signal in response to the at least one control signal. The transmitted wireless signal may be received by a vehicle operator's mobile station or by a call center, which are each capable of then engaging in remedial actions to remotely ameliorate the undesirable condition.

Method of enabling a remote communications device (106) with a telematics functionality module (150) can include providing a docking apparatus (114) coupled to interface with a vehicle (109). The remote communications device is communicatively coupled to the docking apparatus, wherein the remote communications device is non-enabled with a telematics functionality module (150). The docking apparatus and the remote communications device enable the remote communications device with the telematics functionality module.
摘要:
A method for coexistence of an orthogonal frequency division multiple access (OFDMA) receiver (117) such as a WiMAX receiver with a synchronous frame-based transmitter (115) such as a Bluetooth transmitter within a mobile station (110) receives an estimated media access protocol (MAP′) signal indicating when a MAP message is expected to be received by the OFDMA receiver (117) and uses it at a Bluetooth shutdown signal (190) at least when a MAP message is expected to be received. The MAP′ signal can be taken directly from the ODFMA transceiver (117) or it may be produced through analysis of a receiver-enable (RXE) signal that includes not only MAP symbols but also downlink data symbols. The RXE signal can be analyzed using interrupt-and-timer, Fast Fourier Transform, covariance, and/or delay-locked loop techniques to extract historical MAP symbol information and generate expected MAP symbol information. Shutting down a Bluetooth transmitter during expected MAP message receipt permits the OFDMA receiver to maintain synchronicity with an access point while not requiring the Bluetooth transmitter to shut down every time the OFDMA receiver expects to receive an OFDMA symbol.
摘要:
A method, a tap initiator, and tap target in a close proximity communication are disclosed. A tap interface 106 may initiate a tap with a tap target 104. The tap interface 108 may receive a tap from a tap initiator 102. A tap gauge 110 may measure a tap duration between the tap initiator 102 and the tap target 104. A processor 304 may determine if the tap duration is within a first duration range and a second duration range and executes a first action for the first duration range and a second action for the second duration range.
摘要:
An apparatus and method for allowing emergency calling with a Global System for Mobile (GSM) radiotelephone during temperature extremes includes a Subscriber Identification Module (SIM) card, a temperature sensor; and a controller that detects when the radiotelephone has a SIM card error, whereupon the controller obtains a temperature measurement from the temperature sensor. If it is found that the temperature measurement is outside of an operating temperature range of the SIM card, the controller permits the radiotelephone to make an emergency calls only.

A method for coupling location information from a vehicle includes the steps of providing a WLAN communication device with a controller in the vehicle; detecting an emergency condition; and attempting to create a communication link with a portable WLAN enabled device. A system for coupling location information from a vehicle includes a WLAN communication device with a controller installed in a vehicle; a WLAN enabled device in communication with the WLAN enabled controller in the vehicle using a WLAN protocol in response to an emergency condition; a wireless communication network in communication with the WLAN enabled device; and a public safety answering point in communication with the wireless communication network.
摘要:
A vehicle Telematics unit includes a cellular transceiver and a satellite receiver. At least one controller controls the transceiver and the receiver and determines which one to use to communicate with a source of Telematics service. If the transceiver is to be used, the controller receives messages in cellular communications from the source with a cellular network. If the receiver is to be used, the controller receives messages in satellite communications from the source with a satellite network. The controller can programmably control power from a battery to the transceiver and receiver when the vehicle is turned off using discontinuous reception parameters, designated on/off times, a controlled duration, and programmable timers. The transceiver is used to return acknowledgments of messages received. If a message is received with the receiver, the acknowledgment is stored so it can be sent at another time when the transceiver is to be used.

A system and method in a client device (22) for controlling the power within the client device (22). The client device (22) has a network access device (30, 130), a programmable timer (48), and a controller (42). The network access device (30, 130) has at least a powered state and a power-off state.

The controller (42) is coupled to the programmable timer (48) and is capable of providing a time period for operating the network access device (30, 130) in the powered state. The controller (42) determines the time period based on a discontinuous reception (DRX) parameter obtained from the network access device (30, 130). The network access device (130) may include a transceiver. The network access device (30) may also include a transceiver and a controller. There are also methods of operating the client device (22) to control the power within the device.
