Abstract: A telematics system for a vehicle includes an infotainment module, a codec module, and a control module. The infotainment module outputs data to a speaker via a first audio data path. The codec module outputs data to the speaker via a second audio data path when a telematics function of the telematics system is triggered. The control module switches from the first audio data path to the second audio data path after the telematics function is triggered. The control module changes a state of a relay of the speaker and a gain of the codec module in a first predetermined order before outputting data to the speaker via the second audio data path.

Abstract: An in-vehicle wireless communications device executes an emergency report operation to transmit an emergency report signal from a wireless communications unit to a wireless communications network. During this emergency report operation, integrated electric currents from an in-vehicle battery to an in-vehicle wireless communications device reach a predetermined value, which generates an interrupt. Even at this time, stopping of an operation power from the in-vehicle battery to the wireless communications unit is suspended until the emergency report operation is normally finished.

Abstract: A vehicle communication system includes a connection quality module and a channel scan frequency module. The connection quality module determines that a vehicle is out-of-range (OOR) from a host when a connection quality between the vehicle and the host is below a predetermined connection quality threshold. The channel scan frequency module controls a frequency of attempts by the vehicle to connect to the host when the vehicle is OOR based on at least one of whether an engine is on and a movement rate of the vehicle.

Abstract: A method for reactivating a telematics device configured to make a data call via a roaming partner of a service provider is disclosed. The service provider has an authentication bypass feature which uses an authentication bypass key common to the telematics device and the service provider to allow the telematics device to make a data call without authentication. The method comprises setting the authentication bypass key on a server of the service provider equal to a previous authentication bypass key, wherein the previous authentication bypass key was used by the authentication bypass feature prior to deactivation of the telematics device. The method includes setting the authentication bypass key on the telematics device equal to the previous authentication bypass key. The method further comprises commencing the data call through the roaming partner by sending the authentication bypass key to the service provider from the telematics device via the roaming partner.

Abstract: A method of wireless communication between a base station and a mobile station may entail scanning a first entry of a preferred roaming list for a first base station channel, transmitting a downlink signal from the base station to the mobile station; determining that the downlink signal to the mobile station from the base station has not been received, scanning the preferred roaming list for a second base station, identifying that the second base station does not exist on the preferred roaming list, and inquiring whether a vehicle ignition is off upon determining that the second base station does not exist. Moreover, the method may entail determining that the vehicle ignition is on, and return an excluded channel of a base station to the preferred roaming list and determine that the vehicle ignition is off and invoke a sleep mode of the digital control module.

Abstract: A method of registering a vehicle with a call center of a telematics system may entail turning a key within a vehicle ignition to begin a call from a telematics control module within the vehicle to a server at a telematics call center, connecting the telematics control module within the vehicle to the server at the telematics service center, sending a health check request from the telematics control module within the vehicle to the server at the telematics service center; and receiving a health check confirmation in the telematics control module within the vehicle from the server at the telematics service center. The method may further entail inquiring if such a health check request request-confirmation was successful. The method may also include a call fail counter and a message fail counter to automatically re-initiate a health check request and a successful answer to such a request.

Abstract: A vehicular wireless apparatus continues a standby state even after an ACC switch of the vehicle is turned off. In the vehicular wireless apparatus, when it is determined that the ACC switch is turned from on to off, paging area information stored in a RAM (volatile memory) is stored in an EEPROM (nonvolatile memory). When the ACC switch is then turned from off to on, a power-on-reset is done for the whole of the vehicular wireless apparatus and paging area information stored in the RAM is reset. The paging area information stored in the EEPROM is then read. Whether a location registration should be newly done is determined based on the read paging area information.

Abstract: In an on-vehicle radio communication apparatus, when the battery is in a voltage discharging state, every time a predetermined period pases, a current consumption value is updated for the radio circuit by integrating the current consumption for steady operation of the radio circuit. In addition, every time an event occurs in the radio circuit, the current consumption value is updated for the radio circuit by integrating the current consumption for the event operation. If the current consumption value is greater than or equal to a predetermined threshold value, the operation is stopped.

Abstract: When a cell phone fails in location registry to a base station, it removes the base station from a candidate group. Then it searches for and captures, for the next location registry, a base station whose pilot signal has the highest electric field intensity among the updated candidate group. When the registry is yet to be successful, the cell phone prohibits the location registry with maintaining an idle (waiting) state. Here, the pilot signals are observed among the candidate group. When a certain base station whose pilot signal exceeds a preset level of electric field intensity is detected, the idle handoff to the certain base station is executed. This success of the idle handoff then resumes the location registry to the certain base station.

Abstract: A wireless device in a vehicle interfaces with an associated device having a user interface. A wireless circuit included in the wireless device establishes a communications link with a wireless network while the associated device functioning as an end terminal communicates with the network via the communications link. When the interface between the wireless device and associated device is disrupted, the wireless device intentionally disconnects the communications link with the wireless network.

Abstract: An in-vehicle wireless communications device receives an incoming signal via a wireless communications unit from the wireless communications network. When the in-vehicle battery is being discharged, the type of the incoming signal is determined. When the incoming signal is for a voice call, a packet communications, or a TV phone, no incoming process for the received incoming signal takes place. In contrast, when the incoming signal received by the wireless communications circuit from the wireless communications network is an incoming signal for a short message service that becomes a trigger for vehicle remote monitoring or vehicle remote control, an incoming process to the received incoming signal is executed.
