摘要： The present invention relates to an IPv6-based access device, edge router and method for stainless address configuration for IPv6 user equipment in an Ethernet access network, wherein, the access device adds the relay agent ID indicating the access device itself and the relevant port identifier indicating the user equipment to a router solicitation message sent by the user equipment in the form of a newly defined option, and forwards the message to the relevant edge router; and the edge router configures a dedicated address prefix for the user equipment according to the relay agent ID and port identifier, combines the address prefix, the relay ID and the port identifier into a router response message, and sends the response message to the relevant access equipment indicated by the relay ID; the access device sends a router advertisement message only including the address prefix via the line port indicated by the port identifier to user equipment. By allocating the dedicated address prefix to every data subscriber line for IPv6 service, IPv6 stainless address configuration is achieved to solve the security and scalability problems in the prior art.

摘要： Wi-Fi based position information communicating methods, vehicle mounted communication devices, and pedestrian devices are provided. One of the methods includes: a communication device mounted on a first vehicle determining whether position information of a second vehicle, whose distance to the first vehicle is shorter than a first predetermined distance, is received within a first predefined time period; and if no, broadcasting position information of the first vehicle in a first 802.11 management frame. By employing the methods, pedestrian detection rate may be improved and wireless channel congestion may be mitigated.
