This invention discloses a non-intrusive dynamic bridging method for heterogeneous elevator communication protocols, belonging to the field of data communication technology. It includes constructing a protocol sandbox environment isolated from the real communication link; injecting protocol probe agents into the protocol sandbox environment; generating probe agent instances within the protocol sandbox environment; guiding virtual endpoints to perform interactive probing according to an initial exploration strategy; generating an interactive probing dataset and performing protocol rule analysis; reverse-engineering the description rules of the target private communication protocol; generating a protocol rule base; and securely migrating from the protocol sandbox environment to a real-time running protocol conversion module to perform protocol conversion processing on the real-time communication data between the real elevator controller and the external management platform, thus achieving heterogeneous protocol bridging. By automatically reversing protocol rules through agent probing in the isolated sandbox, the parsing and heterogeneous bridging of unknown private communication protocols can be automatically achieved without affecting the operational safety of the real equipment.

This invention discloses an integrated communication system and method based on a next-generation private communication network. The system includes an access network unit, an internal core network unit, and a virtual switch, all deployed on the same hardware processing board and sharing the same operating system kernel. The access network unit establishes a connection with the external core network unit through a first communication interface to form an external communication link. The access network unit connects to the virtual switch through a pre-configured second communication interface, and the internal core network unit connects to the virtual switch through a pre-configured third communication interface. Data forwarding via the virtual switch forms an internal communication link between the access network unit and the internal core network unit. This communication system, firstly, reduces assembly costs and overall hardware costs by using a shared single board and kernel, improving the resource utilization of a single board and making network construction simpler and more efficient; secondly, the two links do not interfere with each other, ensuring the security of internal and external data transmission.

A method and a device for pairing a terminal provided with a near-field communication module over a private network having an access point provided with a near-field communication module. The access point is located in the immediate vicinity of a user, the access point being able to communicate with the terminal: over a first near-field communication channel using the electromagnetic wave conduction capacities of the user's body; and: over a second channel that is separate from the first channel. The method includes, at the access point: obtaining a connection request message over the first channel when the user performs a motion to enter the immediate vicinity of the terminal; transmitting a connection message including a network password; and pairing the terminal over the private network.

An example method is provided for conducting differentially private communication of training data for training a machine-learned model. Initial label data can be obtained that corresponds to feature data. A plurality of label bins can be determined to respectively provide representative values for initial label values assigned to the plurality of label bins. Noised label data can be generated, based on a probability distribution over the plurality of label bins, to correspond to the initial label data, the probability distribution characterized by, for a respective noised label corresponding to a respective initial label of the initial label data, a first probability for returning a representative value of a label bin to which the respective initial label is assigned, and a second probability for returning another value. The noised label data can be communicated for training the machine-learned model.
