In an aspect of the present disclosure, there is provided a method of transmitting a vehicle-to-pedestrian (V2P) message. The method may comprise checking whether a timer is running, generating and storing an identifier when the timer is not running, encoding a personal safety message (PSM) according to a predetermined method and storing the encoded PSM as a lead V2P message and transmitting the generated identifier and the lead V2P message.

In an aspect of the present disclosure, there is provided a road side apparatus configured to relay a message. The apparatus may include a memory, a processor, and a transceiver. The processor may be configured to: check whether an identifier received together with a received message is previously stored; when the identifier is stored, replace a personal safety message (PSM) corresponding to the identifier in a pair of the PSM and the identifier with a PSM included in the received message and the store the PSM; when a timer for batch transmission expires or when a total size of stored PSMs exceeds a predetermined value, generate one batch message including all PSMs in stored pairs of PSMs and identifiers; and transmit the generated batch message. The identifier may be information for identifying a transmitter that transmits the message.

The embodiments of the present disclosure provide a method and apparatus for distinguishing between data formats, and a communication device. The method includes a terminal receives a downlink data packet, and determines whether the data format of the downlink data packet is a first data format or a second data format, wherein the first data format indicates that the downlink data packet is encrypted using a first key of a source base station and/or compressed using a first header compression format of the source base station, and the second data format indicates that the downlink data packet is encrypted using a second key of a target base station and/or compressed using a second header compression format of the target base station.

A terminal includes a transmitting unit that transmits a signaling message including information indicating a context to be established with a base station when there is one device corresponding to a transmission source address of the context to be established with the base station, the one device being connected to the terminal; and a control unit that attaches, to data, a compressed header corresponding to the context, when the data received from the one device is to be transmitted after transmitting the signaling message, wherein the transmitting unit transmits, to the base station, the data to which the compressed header is attached, the data not including a context identifier for identifying the context.

A multipath device for processing multipath data traffic, the multipath device comprising: a multipath network access interface for receiving multipath data traffic; and a host processor configured to process a plurality of multi-connectivity network protocols. A specific multi-connectivity network protocol of the plurality of multi-connectivity network protocols is configured to utilize protocol-specific resources of the multipath device for processing a portion of the multipath data traffic that is related to the specific multi-connectivity network protocol. The specific multi-connectivity network protocol is configured to share the network protocol-specific resources with other multi-connectivity network protocols which are configured to process portions of the multipath data traffic that are related to the other multi-connectivity network protocols by distributing payload data transport onto multiple sub-flows of a multipath connection.

This application provides a data transmission method and apparatus. The method includes: obtaining significant bits in an N.sup.th data frame, where N is an integer greater than or equal to 1, a quantity of the significant bits in the N.sup.th data frame is smaller than a quantity of bits in the N.sup.th data frame, and remaining bits other than the significant bits in the N.sup.th data frame are insignificant bits in the N.sup.th data frame; and sending the significant bits in the N.sup.th data frame, and skipping sending the insignificant bits in the N.sup.th data frame. According to the application, on a premise of ensuring voice intelligibility, a transmit end apparatus transmits only the significant bits, to minimize a data transmission amount, thereby improving transmission reliability and coverage.

A method for an online video game or application service system includes running a video game or application on an application host server at a data center, an uncompressed video stream being produced therefrom. The uncompressed video stream is encoded into compressed video stream, which is then transmitted over the Internet to an output client device of a user. The output client device decompresses the compressed video stream and displays live video on a screen. User control input transmitted from an input client device is delivered to the application host server. The user control input includes game or application commands. The input client device is associated with the user and is separate from the output client device. Responsive to receiving the game or application commands, the application host server generates a new uncompressed video stream.
