  • Publication number: 20230014413
    Abstract: This application relates to an access control method, applied to the field of short-range communication, for example, cockpit domain communication. The method includes: determining that a status of a first device is a first status; and sending first indication information, where the first indication information is used to indicate whether access of at least one second device to the first device is allowed. A system broadcast message carrying system status information is sent, so that after a non-vehicle-mounted device receives the system broadcast message, the non-vehicle-mounted device determines, based on the system status information, whether to initiate a random access request. This avoids impact, caused by random access request initiation performed by the non-vehicle-mounted device in this phase, on checking a status of a vehicle-mounted device performed by a CDC and self-check and access performed by the vehicle-mounted device.

  • Publication number: 20220272038
    Abstract: Data routing with a forwarding process of service data can avoid problems of offline nodes. The forwarding process for data routing can also improve the fault tolerance and service data can be quickly transmitted to a corresponding data pool. Using consensus nodes and a target data pool with routing and forwarding tables along with subtrees from a trie tree can improve the routing. Subtrees may be obtained by splitting the trie tree from a root node by using a first leaf node as a benchmark, which correspondingly represents a data pool of the consensus node. The routing and forwarding table is configured to record addresses of data pools correspondingly represented by a preset quantity of leaf nodes in a corresponding subtree.
