This invention discloses a preamble-free access TA synchronization method and apparatus that saves time-domain resources, comprising: coarse search for candidate TAs: selecting multiple TA candidates within a preset range with a fixed step size; signal preprocessing: receiving repeatedly transmitted Msg3 frames and obtaining the frequency domain data corresponding to each TA candidate; parallel soft combining and score calculation: performing channel estimation, equalization, and descrambling on each candidate data in parallel to obtain descrambling LLR soft bits, and accumulating their absolute values ​​to calculate the synchronization score of each candidate; candidate selection and decoding verification: sorting by score and selecting high-scoring candidates for decoding and CRC verification; synchronization confirmation: using the successfully verified TA as the final synchronization quantity. This invention saves preamble time slots and response windows, significantly reducing access latency and resource consumption.

The application provides a cockpit implementation method and system based on emotion enhancement and scenario service flow intelligent agent, and belongs to the technical field of automobile intelligent cockpits. The method comprises the following steps: acquiring multi-modal data of a target user in real time, fusing the multi-modal data to generate comprehensive user states, planning a service flow based on scenario semantics and the user states, and generating and outputting action execution instructions of internal and external resources according to the service flow. Through multi-modal deep fusion and scenario semantic understanding, the application can accurately capture user states and demands, provide the most suitable service at the most appropriate time, and change passive response into active care. The application sets a user memory vector library to continuously learn and adapt to user preferences, provides a truly 'thousand faces for a thousand people' service, and as the use time increases, the service accuracy and user satisfaction present a continuously rising curve, thereby solving the problem of static experience of traditional systems.

This application provides an emergency communication system and method. The system includes: airborne equipment, a satellite communication system, and a public network core network device. The airborne equipment is connected to the satellite communication system via a satellite link, and the satellite communication system is connected to the public network core network device via a pre-set dedicated line link. The airborne equipment is used to provide a first emergency communication requirement for the emergency area and perform localized processing operations based on the first emergency communication requirement. The satellite communication system is used to provide transmission routing between the airborne equipment and the public network core network device. The public network core network device is used to provide a second emergency communication requirement for the emergency area and perform emergency processing control operations based on the second emergency communication requirement. This application can solve the problem that existing emergency communication solutions have limitations and cannot simultaneously provide diverse services to emergency rescue personnel, disaster victims, etc., thus affecting rescue efficiency.
