Abstract: A battery-powered wireless content loader for an entertainment system of a vehicle includes a multi-mode wireless data communications module with at least a first communications mode and a second communications mode. A controller establishes a data link to a remote content server with the multi-mode wireless data communications module to retrieve multimedia content from the remote content server. The controller selects either one or both of the communications modes based at least in part upon an evaluation of availability of an access point for the first communications mode within range. A data storage device stores the retrieved multimedia content. An electrical power storage supplies power in response to the vehicle being powered down. The controller copies the multimedia content stored on the data storage device to a content server of the entertainment system following the electrical system of the vehicle being powered up.

Abstract: A distribution system for vehicle information systems and methods for manufacturing and using the same. The distribution system supports both Wi-Fi- and cellular-based wireless networks for the distribution of selected content to a plurality of handheld devices disposed throughout a passenger vehicle via a bypass system (e.g., a Local Internet Protocol Access (LIPA) and Selected Internet Protocol Traffic Offload (SIPTO) bypass system). In an alternative embodiment, the distribution system can be configured for distribution of the selected content from a terrestrial content system to a plurality of passenger vehicles via the bypass system. By dynamically balancing network traffic across the multiple wireless networks, the distribution system can alleviate heavy traffic network and bypass a service provider's cellular core network to optimize signal bandwidth and network performance.

Abstract: The methods, apparatus, systems and computer program products provide for sensing a magnetic field, emitted by a short-range communication source, to activate short-range communication modules in a mobile terminal. In addition to sensing the magnetic field, the terminal may rely on other parameters, such as operational state of the terminal, contextual information and the like, to determine if the short-range communication module should be activated. As such, the invention reduces the overall power consumption of the terminal by limiting the active state of the short-range communication module. By conserving power the mobile terminal is capable of operating for longer periods of time without requiring charging or replacement of the power supply.

Abstract: The invention relates to a method for discovering services for a wireless multimode terminal with a plurality of radio interfaces. In order to improve the efficiency of a wireless multimode terminal in terms of power consumption and user-friendliness, an indication is sent to a multimode terminal in the mobile network, the indication indicating that services may be locally available for the multimode terminal via at least one short-range wireless network. The indication is received in the multimode terminal, and information is collected, based on the indication, about services available via at least one short-range wireless network. Based on the information collected, a service list is then compiled, the list describing at least one service available locally in one or more short-range wireless networks.

Abstract: A method and arrangement for connecting an ad-hoc communication network (101) to a permanent communication network (102) via a half-duplex communication link (140). The ad-hoc communication network is established between communication devices (103-106) and a gateway device (107) using a routing protocol that is run in the gateway device and in the communication devices. Relaying of data between the ad-hoc communication network and the permanent communication network is controlled by setting the following relaying operations into a pre-determined order of mutual priority: relaying data from the ad-hoc communication network to the permanent communication network and relaying data from the permanent communication network to the ad-hoc communication network. The pre-determined order of priority facilitates data transfer via the half-duplex communication link between the permanent communication network and the ad-hoc communication network that can be either a full-duplex network or a half-duplex network.

Abstract: A method and arrangement for connecting an ad-hoc communication network (101) to a permanent communication network (102), e.g. to a cellular mobile communication network. The ad-hoc communication network is established between communication devices (103-106) and a gateway device (107) using a routing protocol that is run in the gateway device and in the communication devices. A protocol address that is associated in a communication device with a protocol data unit is determined on the basis of a control action given by a user of the communication device. In a gateway device, the protocol data unit is relayed to the permanent communication network if the protocol data unit is provided with a pre-determined protocol address. The user of the communication device can determine with the aid of the control action whether he is communicating only inside the ad-hoc communication network or via the permanent communication network.

Abstract: The invention relates to a method for controlling the operation of a short-range wireless terminal capable of operating in a first beacon-based network and in a second beacon-based network, and having an active state and a power save state in the first beacon-based network. For seamless operation in the two networks, the terminal moves to a power save state with respect to the first beacon-based network if operation in the second beacon-based network is required. However, the first beacon-based network is only informed that the terminal moves to a power save state and instead of powering down, the terminal becomes active in the second beacon-based network.
