Abstract: An information processing method provided in the present disclosure includes: allocating, to a Non-Terrestrial Network (NTN) cell, at least one of a frequency band dedicated to the NTN cell, a frequency dedicated to the NTN cell, and a Physical Cell Identifier (PCI) dedicated to the NTN cell; notifying User Equipment (UE) of at least one of the following information: a frequency band indicator of the frequency band, the frequency, and the PCI.

Abstract: A wireless terminal determines a tracking area code (TAC) from a geographic position of the wireless terminal. From the TAC, the wireless terminal determines the tracking area identity based on an indication from the network-side regarding whether or not geographic position based tracking area identity determination is to be used or not. In some implementations, the network-side is a satellite cell that is configured to provide wireless connectivity to the wireless terminal.

Abstract: A composite equal additive manufacturing method: S1, obtaining molten metal by using a metal smelting device; S2, first, storing inflow molten metal in an intermediate container, and then transferring the molten metal into a crystallizer; S3, cooling the molten metal to a solid-liquid mixed state by using the crystallizer, and enabling a high-temperature blank body with a required section to flow out from an outlet of the crystallizer; S4, arranging plastic forming tools at a bottom of the outlet of the crystallizer, and performing plastic forming on the outflow high-temperature blank body; S5, fixing a lower end of a part after the plastic forming and slowly descending the part by a chuck; S6, machining the part by using point forming machines, and synchronously controlling the machining temperature of the part; and S7, descending the chuck to an appropriate position, and taking the formed part out from the machine frame.

Abstract: The present disclosure discloses a method, device and system for synchronously playing a message stream and an audio-video stream, and involves in the field of streaming media live broadcast technology. In the present disclosure, a stream-pulling terminal pulls an audio-video stream from an audio-video server and plays the audio-video stream, pulls a message stream from a message server and caches the message stream (201). Herein, each audio-video frame in the audio-video stream is supplemented with an audio-video timestamp, each message in the message stream is supplemented with a message timestamp, and time sources taken by the audio-video timestamp and of the message timestamp are synchronous time sources. The stream-pulling terminal determines a message synchronously played with an audio-video frame to be played in a cached message stream in accordance with the audio-video timestamp of the audio-video frame and the message timestamp of the message, and plays the message (202).
