Provided is a dynamic automation level-based autonomous driving system and a method thereof, and more particularly, an autonomous driving system that preferentially performs maximum autonomous driving based on a dynamic automation level in bad weather and irregular road environments and a method thereof. The dynamic automation level-based autonomous driving system includes a route server configured to generate operational design domain determination information and to plan a global route so that an automated driving mode is preferenced, and an autonomous vehicle configured to drive along the global route, to change automation levels by using multi-layer operational design domain definition information and driving situation monitoring information, and to perform autonomous driving.

A method for rerouting communication in a unified communications network. The method comprises: receiving, at a disaster plan server, a mapping of an original telephony number to a substitute telephony number; storing, at the disaster plan server, the mapping between the original telephony number and the substitute telephone number as part of a disaster plan; receiving, at a disaster plan server, a request to activate the disaster plan; transmitting, from the disaster plan server to a routing server, a message to activate the disaster plan based on receiving the request to activate the disaster plan; revising, at the routing server, routing details to the original telephony number based on the disaster plan; and routing, at a session border controller, a call to the original telephony number to a new destination based on the revised routing details associated with the disaster plan.

The invention discloses an intelligent parking lock ad hoc network communication and network fault prediction method and device, and belongs to the technical field of intelligent parking. The method comprises the following steps that: each parking lock node periodically acquires signal intensity of a neighbor node and battery voltage data of the parking lock node and reports the signal intensity and the battery voltage data; the server constructs an adjacent matrix and a degree matrix of the parking lock network according to the reported data, and further calculates a Laplacian matrix; a node capable of being directly connected with a gateway is used as an initial cluster head, and multi-stage cluster-shaped routing is constructed based on electric quantity and signal intensity threshold value iteration; and the server periodically updates the Laplacian matrix and performs eigenvalue decomposition, the overall connectivity of the network is judged according to the second small eigenvalue lambda, a connectivity weak area is positioned according to the variation amplitude of elements in the corresponding eigenvector, and fault prediction is realized. The device comprises a parking lock node, a gateway and a server. According to the invention, long-distance and low-power-consumption wide-coverage communication is realized, network faults can be actively predicted, and the reliability and the operation and maintenance efficiency of the parking system are remarkably improved.

This invention discloses a video conferencing migration method, apparatus, system, medium, and device. The method includes: receiving video conferencing takeover information from a signaling routing server; obtaining meeting attribute information of the video conferencing to be taken over from a database server based on the video conferencing takeover information; obtaining participant attribute information from the user terminal devices of the migrated valid participants among the original participants of the video conferencing to be taken over; and performing a reconstruction operation of the video conferencing to be taken over based on the meeting attribute information and the participant attribute information of the migrated valid participants, so as to migrate the video conferencing to be taken over to the signaling server. The technical solution provided by this disclosure can minimize the time cost, computational cost, and storage cost of video conferencing migration while ensuring the accuracy of the migrated video conferencing as much as possible, thereby helping to shield the impact of signaling server-side failures on the video conferencing.
