Abstract: Embodiments of this application disclose a relay transmission method and system, and a related device. The method includes: determining, by a relay terminal, a vehicle existing between a vehicle terminal i and a vehicle terminal j based on vehicle location information in received broadcast messages sent by N vehicle terminals; and when it is obtained through calculation that link quality of a communication link Rij used when the vehicle terminal i and the vehicle terminal j communicate with each other is lower than a preset threshold, forwarding, to the vehicle terminal j, a broadcast message sent by the vehicle terminal i, and forwarding, to the vehicle terminal i, a broadcast message sent by the vehicle terminal j. A relay forwarding function of the relay terminal avoids communication interruption or communication distance limitation caused by blocking due to dynamic and unpredictable factors such as a large vehicle within the Internet of vehicles, thereby improving reliability of message transmission within the Internet of vehicles.

Abstract: A signal encoding method and device are disclosed. The method includes, when an encoding manner of a previous frame of a currently-input frame is a continuous encoding manner, predicting a comfort noise that is generated by a decoder according to the currently-input frame when the currently-input frame is encoded into an SID frame, determining an actual silence signal, determining a deviation degree between the comfort noise and the actual silence signal, determining an encoding manner of the currently-input frame according to the deviation degree, and encoding the currently-input frame according to the encoding manner of the currently-input frame. It is determined, according to the deviation degree between the comfort noise and the actual silence signal, that the encoding manner of the currently-input frame is the hangover frame encoding manner or the SID frame encoding manner, which can save communication bandwidth.

Abstract: The present application relates to the field of computer technologies, and in particular, to a stop word identification method used in an information retrieval system. In a stop word identification method, after a first query input by a user is acquired, a second query that belongs to a same session as the first query is acquired, and a stop word in the first query is identified according to a change-based feature of each word in the first query relative to the second query. According to the solution provided by the present application, a stop word in a query can be identified more accurately, and efficiency and precision of an information retrieval system are improved.
