A method and an apparatus are disclosed for providing a next-generation network service in a heterogeneous network environment. The present disclosure in some embodiments provides a method and an apparatus, which can operate a conventional network and a next-generation network in an interworking arrangement with high reliability, and can process high-speed data communications by using the next-generation network.

A communication apparatus for vehicle-to-X communication (V2X communication), including: a first V2X interface for transmitting and/or receiving vehicle-to-X messages by a first wireless communication technology, a second V2X interface for transmitting and/or receiving vehicle-to-X messages by a second wireless communication technology. Wherein the apparatus is configured to transmit information, which is received with a vehicle-to-X message by the first interface, by the second interface. The information received or respectively to be transmitted can be expediently had by at least one appropriate vehicle-to-X message received or respectively to be transmitted. A corresponding method as well as the use of the apparatus is also provided.

An object of the present invention is to provide a roadside communication apparatus and an in-vehicle communication apparatus capable of reducing an increase in a traffic amount in a roadside-to-vehicle communication. A roadside communication apparatus according to the present invention includes: an inter-vehicle transmission-and-reception service processing unit transmitting and receiving a roadside-to-vehicle message and an inter-vehicle message; a communication transfer unit providing a transaction service and a transfer service; a roadside-to-vehicle application processing unit; an inter-vehicle application processing unit; a transmission-and-reception condition management unit managing a transmission-and-reception condition of an inter-vehicle message which the inter-vehicle application processing unit transmits to and receives from the communication device; and a roadside communication management unit managing a connection state with the communication device, wherein the roadside communication management unit manages a connection state with the communication device based on a reception condition of the inter-vehicle message notified by the transmission-and-reception condition management unit.

A plug-in network device is disclosed. The plug-in network device can be used in association with a network management system and an infrastructure network device. The plug-in network device includes two antenna arrays, one of which is up-facing and one of which is front-facing. The plug-in network device can achieve wireless communication with the infrastructure network device via the up-facing antenna array and provide network services to wireless stations through the front-facing antenna array. The network management system can manage both the infrastructure network device and the plug-in network device.

Apparatus and methods for a reverse proxy server are provided. The reverse proxy server may provide compatibility and security for nodes on an IoT network. A reverse proxy server may normalize inter-node communications. A reverse proxy server may identify an IoT node and upon identification of the node, determine native communication protocol(s) specific to the node. The reverse proxy server may encapsulate data transmitted via the native communication protocol. The reverse proxy server may impose a principal-agent relationship. For example, the reverse proxy server may be a principal of one or more nodes (agents) on the IoT. The reverse proxy server may enforce security protocols on all agents. An agent (e.g., node) may be required to route all communications to other IoT devices through the principal (e.g., reverse proxy server). An IoT network may include more than one reverse proxy server. Each agent may have one or more principals.

Devices in a wireless telecommunication system can implement a blockchain that is distributed among the devices. For example, a base transceiver station of the wireless telecommunication system can receive, from a mobile device, a wireless radio communication that includes information associated with a blockchain transaction. The base transceiver station can convert the information associated with the blockchain transaction into an internet protocol (IP)-based format. The base transceiver station can update the blockchain by propagating the formatted information to other base transceiver stations of the wireless telecommunication system through an IP-based network that is internal to the wireless telecommunication system.

A data communications network having a plurality of remote input units providing data, a data server for storing data, and subscriber units consuming data. The data communications network controls and manages the receipt of the data originating from the remote input, the processing of the data in a form suitable for the subscriber units, and the distribution of the processed data to the subscriber units.

An asynchronous switching system and method for processing SDI data streams, the system and method utilizing one or more buffers for cleaning up an output of a dirty IP switch.

A device, system and method for communicating between devices using two protocols is provided. A request is received from a first device to communicate with a second device. A dedicated client operates according to a first protocol. A call server is operated according to a second protocol. An identifier is provided to the second device for requesting a web application for conducting a call via the call server, the identifier associated with the first and second device. A request, including the identifier is received and the web application is provided to the second device. A first call is set up between the dedicated client and a respective dedicated client. A second call is set up between the call server and the web application at the second device. The first call and the second call are connected to conduct an end-to-end call between the first and second device.
