A method in one embodiment includes detecting a trigger on an electronic device and identifying an interface usage policy for an agent and a corresponding application on the electronic device. The method also includes selecting a first wireless interface of a plurality of wireless interfaces on the electronic device for a network session between an application process of the application and a remote node, with the first wireless interface being selected based on one or more criteria in the interface usage policy. In specific embodiments the electronic device is an on-board unit of a vehicle. In more specific embodiments a second wireless interface is selected based on the interface usage policy, the first and second wireless interfaces are different physical interfaces on the electronic device. In other specific embodiments, the first and second wireless interfaces are virtual interfaces of a single physical interface on the electronic device.

A method in one example embodiment includes identifying a power state and a battery level of a vehicle. The method also includes allocating power to critical applications (for example) in response to determining that the battery level is above a reserve threshold while the power state of the vehicle is engine-off. The method also includes allocating remaining power in excess of the reserve threshold to non-critical applications according to a power management policy. The power management policy may comprise at least one of a user power preference index and an application power preference index.

A method in one embodiment includes detecting an event for a transaction on an on-board unit (OBU) of a vehicle, where the event has a trigger associated with an agent. The method also includes determining whether the transaction is authorized, identifying network credentials in an identity profile that corresponds to the agent, providing network credentials to a transaction application corresponding to the transaction, and accessing a remote network using the network credentials. Certain embodiments include selecting the network credentials from a plurality of available network credentials corresponding to the agent. In more specific embodiments, the network credentials include one or more virtual subscriber identity modules (VSIMs) of a plurality of VSIMs provisioned on the OBU. In specific embodiments, the network credentials are mapped to a combination of two or more of the agent, the transaction application, and a predefined current location of the vehicle.

A method includes establishing communication channels between an on-board unit (OBU) of a vehicle and a plurality of nodes, tagging each of a plurality of data from the plurality of nodes with a priority level, storing the plurality of data in a priority queue according to respective priority levels, selecting a medium to present a first data of the plurality of data to a user, and presenting the first data to the user via the medium. In the method, the plurality of nodes includes a remote node and an in-vehicle device. Another method includes receiving a data from a remote node, generating a plurality of data streams from the data and transmitting the plurality of data streams across a plurality of wireless interfaces. Another method includes enhancing audio signals from a plurality of microphones and speakers. Yet another method includes various gesture based user interfaces coupled to the OBU.

A method is provided in one example embodiment that includes receiving a request for data from a source device, such as an on-board unit of vehicle or a mobile device coupled to an on-board unit, over a vehicular network. Location data, such as GPS coordinates, speed, and heading associated with the source device may also be received. A travel path for the source device can be predicted based on the location data, and an access point to the network can be located within range of the travel path. Packets associated with the requested data may be sent to the access point and then forwarded to the source device when the source device is in range.

A method in one embodiment includes maintaining a list of authorized devices; creating an association between a wireless device being operated by an end user and an onboard unit (OBU) element, which is provisioned in a vehicle; establishing a session over a designated port for an application to be executed on the OBU element; and accessing resources associated with the vehicle through the OBU element. In other examples, authentication of the wireless device can occur via a wired equivalent privacy (WEP) WiFi access point provided by the OBU element. Authentication of the wireless device can also occur via a radio-frequency identification (RFID) tag. The resources can include any number of items such as speakers, a display, a microphone, a global positioning system (GPS) receiver, or any other suitable element that may be provisioned in the vehicle.
摘要:
A method includes selecting a path for routing a data packet from a source node to a destination node in a vehicular ad hoc network, storing the data packet if the selected path is identified as a dead end, and establishing a communication link with a first node. The method also includes forwarding the data packet to the first node if a first distance between the first node and the destination node is less than a second distance between the source node and the destination node. More specific embodiments include sending a query for location information of the destination node, receiving the location information including two or more available paths from the source node to the destination node, and determining the path for routing the data packet is an optimal path of the two or more available paths.
摘要:
A method in one example embodiment includes receiving a set of data in real time from a plurality of machine devices associated with at least one vehicle, providing a set of reference data corresponding to a machine device of the plurality of machine devices, comparing the set of data with the set of reference data, and detecting a deviation within the set of data from the set of reference data. The method further includes initiating an operation associated with the deviation. The set of reference data could be a trend of previous data received from the machine device or a common trend based on a previous set of data of the machine device. More specific embodiments include receiving a plurality of data containing the set of data from the plurality of machine devices and identifying a state of the machine device using the set of data.
摘要:
A method includes joining a vehicular access network (VAN) comprising cooperative communication between a plurality of on-board units (OBU) in respective vehicles, scanning the VAN to pick up a coverage of at least one infrastructure access point (IAP), which operates on a control channel in a radio access tree (RAT) comprising a plurality of cells, listening to a channel allocation information from the IAP that includes a request for a mobile cell gateway (MCG) at a nominal location in the RAT, and sending a candidacy message to the at least one IAP to become an MCG. Certain embodiments include establishing the VAN in a highway, and in urban areas, aggregating traffic in a cell and transmitting to the IAP via the MCG, and other features.
