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:
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:
An apparatus and method for enabling a Near Field Communications (NFC) equipment integrated into a portable communications device, such that when the portable communications device's battery is low the residual charge of the battery is used to power the NFC equipment to enable various NFC applications without causing damage to the battery or portable communications device.
摘要:
A voltage sensing circuit is used to determine when the current supply to a processing unit is under transition. During power up transitions, the voltage sensing circuit allows the processing unit to reset normally. During power down transitions, the voltage sensing circuit prevents the processing unit from resetting until a predetermined procedure has been completed, thereby assuring an orderly shutdown.
