摘要:
This application discloses a vehicle motion status identification method and apparatus, and relates to the field of autonomous driving. In this method, a traveling track of another vehicle may be predicted based on location information and motion information of the another vehicle, and at least two types of the following: lane information of a lane in which the another vehicle is located, lane information of a first adjacent lane of the lane in which the another vehicle is located, and lane information of a second adjacent lane of the lane in which the another vehicle is located, to obtain at least two predicted traveling tracks corresponding to the foregoing at least two types of lane information. Then, a motion status of the another vehicle relative to an ego vehicle may be identified based on the foregoing at least two predicted traveling tracks and lane information of a lane in which the ego vehicle is located, so that sensitivity to instantaneous kinematic information of the another vehicle can be effectively reduced and misidentification of the motion status of the another vehicle can be reduced in monitoring the motion status of the another vehicle relative to the ego vehicle.

This application provides a map update data processing method, apparatus, and system, and relates to the field of autonomous driving technologies. The method includes: obtaining first information from at least one vehicle terminal in a time window, where the vehicle terminal may be a smart vehicle, and the first information does not match corresponding second information in a local map stored in the vehicle terminal; determining, based on the first information, first change information of the second information and precision information and/or confidence information corresponding to the first change information, where the first change information is information about a difference between the first information and the second information; and finally, sending the first change information of the second information and the precision information and/or the confidence information corresponding to the first change information to the at least one vehicle terminal, where the precision information and/or the confidence information corresponding to the first change information is used by the vehicle terminal to determine whether to use the first change information of the second information. The solution provided in this application may be used to improve reliability of crowdsourced map update data.

Embodiments of the present invention provide an IP address allocation system and method, which implement, if a control plane is separated from a forwarding plane, a function that enables user equipment to acquire an IP address in a DHCP manner. The method includes: receiving, by a forwarder, an address request sent by an external network element, where the address request includes a DHCP request of user equipment UE and user characteristic information of the UE; acquiring, from a DHCP service network element according to the DHCP request, an IP address allocated to the UE; and acquiring first instruction information that is delivered by a control device according to the user characteristic information of the UE and the IP address allocated to the UE, and sending the IP address to the UE according to the user characteristic information.

Embodiments of the present invention provide a packet forwarding system, device, and method. The packet forwarding system includes: a gateway control plane entity, configured to send a user profile establishment message to a mobile agent in a process of setting up a bearer, where the user profile establishment message includes a user profile of the bearer; the mobile agent, configured to store the user profile of the bearer; and a switch, configured to: after receiving a user plane packet and when no flow entry matching the user plane packet is found in a local flow table, send a flow entry request including a matching parameter in the user plane packet to the mobile agent, where the mobile agent is further configured to: after receiving the flow entry request, generate, according to the found user profile, a flow entry matching the user plane packet, and send the generated flow entry to the switch; and the switch is further configured to store, in the flow table, the flow entry sent by the mobile agent, and forward the user plane packet according to an instruction set in the flow entry sent by the mobile agent.

The present invention relates to the communications field, and discloses a method, a device, and a system for monitoring quality of an Internet access service of a mobile terminal. The method includes: collecting, by a mobile terminal, an IP data packet of an Internet access service; identifying, by the mobile terminal, an Internet access service type corresponding to the IP data packet; performing, by the mobile terminal, deep packet resolution on the IP data packet to obtain a resolution result; collecting statistics, by the mobile terminal, on a key quality indicator of the Internet access service corresponding to the Internet access service type according to the resolution result of the IP data packet; and uploading, by the mobile terminal, the key quality indicator obtained by means of statistics to a network server, so that the network server monitors quality of the Internet access service of the mobile terminal according to the key quality indicator. By using the present invention, accurate monitoring of quality of an Internet access service of a mobile user can be implemented.
