Disclosed herein is a method for transmitting information for a neighboring vehicle UE of a first vehicle UE using V2X (Vehicle-to-Everything) communication in a wireless communication system. The method includes receiving a first V2X message from at least one the neighboring vehicle UE; generating a second V2X message based on the received first V2X message when an accident triggering an eCall (emergency call) occurs, checking whether the second V2X message is ready to be transmitted to the first network entity; and transmitting at least one of the eCall, a minimum set of data (MSD) forming the data component of the eCall, or the second V2X message to the first network entity according to the result of the check.

Apparatus and associated methods relating to data packet deparsing include an editing circuit configured to perform one or more predetermined editing operations on headers of an incoming data packet step by step without extracting all headers from the incoming data packet. In an illustrative example, an editor circuit may include an updating circuit configured to receive the data packet and update a header in the data packet. The editor circuit may also include a removal circuit configured to remove a header from the data packet. The editor circuit may also include an insertion circuit configured to insert one or more consecutive headers to the data packet. A state machine may be configured to enable or disable the updating circuit, the removal circuit, and/or the insertion circuit based on the predetermined editing operations. By using the editing circuit, packet deparsing may be performed with less hardware resources and low latency.

An enhanced LOng RAnge Navigation (eLORAN) system may include a plurality of eLORAN stations, each having an eLORAN antenna and an eLORAN transmitter that may transmit data over an eLORAN data channel and may transmit a series of eLORAN navigation RF pulses. An eLORAN control station may generate station specific eLORAN data and non-station specific eLORAN data, divide the non-station specific eLORAN data into non-specific eLORAN data subsets, and cause each eLORAN station to transmit the station specific eLORAN data and a corresponding non-station specific eLORAN data subset over the eLORAN data channel in a manner to optimize data throughput.

Internet protocol packets are statelessly identified as associated with a particular session-instance by identifying a key, or session-instance identifier, within the data (or payload) portion of a user plane packet. This identifier is specific to the session-instance and remains constant throughout the session-instance. Using this stateless identification, transmitted user plane packets are automatically routed at the transmission speed of the transmission link using a method that automatically balances the analysis processing load between network probes. The load is balanced by routing the user plane packet to a network probe that is either already analyzing the session-instance or by routing the user plane packet to a system that has processing capacity to analyze a new session-instance. The network probe then analyzes the user plane packet and the session-instance to measure the quality of the user experience of the session-instance and performance of the network.

A service data transmission method includes determining, by a first device, a switching request, and sending, by the first device, the switching request to a second device, where the first device is connected to the second device using a flexible Ethernet (FlexE) group including at least one FlexE connection instance (FlexE Instance). The switching request includes first slot configuration information and second slot configuration information, the switching request is used to request to switch a slot configuration of a FlexE Instance from a configuration indicated by the first slot configuration information to a configuration indicated by the second slot configuration information, and a slot division quantity indicated by the first slot configuration information is different from a slot division quantity indicated by the second slot configuration information.

The present disclosure provides a method, apparatus, and device for PPTP VPN based access acceleration. A PPTP VPN system includes a client-side, a first server, a VPN server, and a second server cluster supporting a GRE protocol connected between the first server and the VPN server. When the client-side starts an accelerated access, the first server receives a first PPTP message and a first GRE message from a same client-side, and encapsulates the first GRE message. An encapsulated first GRE message and the first PPTP message are send to a same second server. The first GRE message is encapsulated and the source addresses of the first GRE message and the first PPTP message are changed. Therefore, the reliability of the transmission can be achieved. Reverse transmission is no difference. The present disclosure accelerates the access speed of the VPN server and improves the access quality of the user.

Embodiments described herein provide a method for fragmenting and reassembling data frames on a medium access control (MAC) layer in a wireless local area network. A datagram is received from an application running on a first network device, for transmission over a wireless communication link in the wireless local area network. A negotiation request is initiated with a second network device for determining whether both the first network device and the second network device have enhanced directional multi-gigabit capability (EDMG) for data segmentation and reassembly. When both devices have EDMG capability and the size of the datagram exceeds the maximum size defined by the wireless local area network transmission protocol, the datagram is segmented into a plurality of transmission data units on the MAC layer.

According to an aspect of the present invention, a communication device includes a communicator for communication with other device in a network to which the communication device belongs and a processor for generating frames to be communicated. The processor generates second identification information different from first identification information which is identification information unique to the communication device based on the first identification information. Further, the processor generates a frame including the second identification information.
