Abstract: The present disclosure is related to network nodes and methods at the network nodes for jointly authenticating a user equipment (UE). A method at a first network node in a first network for jointly authenticating a CE in the first network and a second network comprises: receiving, from a second network node in the second network, a first authentication request for the UE: determining whether the UE is successfully authenticated or not at least partially based on one or more authentication configurations for the first network: and transmitting, to the second network node, a first authentication response indicating whether the UE is successfully authenticated or not based on a result of the determination.

Abstract: A method for resuming cell service including acquiring first geographic location information of a terminal and first time-frequency position information of a cell corresponding to the terminal entering an offline state, the terminal being located in a coverage area of the cell when the terminal enters the offline state, and the cell service being suspended in the offline state, initiating a timer corresponding to the terminal entering the offline state, acquiring second geographic location information of the terminal and stopping the timer corresponding to the terminal exiting the offline state, and resuming the cell service based on the first time-frequency position information and a timer duration based on a determination that the terminal has not left the cell, the timer duration being based on a value of the timer at the stopping, and the determination being based on the first geographic location information and the second geographic location information.

Abstract: Provided is a method for preparing a sucrose-6-ester, including: preparing a reaction solution of sucrose and an organo-tin compound; atomizing the reaction solution to form droplets; thoroughly mixing and contacting the droplets with a gasified dehydration medium such that the droplets undergo a dehydration reaction to obtain an intermediate mixture containing sucrose organic tin ester droplets; separating the intermediate mixture to obtain a sucrose organic tin ester solution and a dehydrated gas-liquid mixture; recovering the sucrose organic tin ester solution obtained in the separation step and cycling to the atomization and dehydration steps several times; and subjecting an organic acid anhydride to an acylation reaction with the sucrose organic tin ester solution to obtain the sucrose-6-ester.

Abstract: Provided is a post-treatment method for a sucrose-6-carboxylate chlorination reaction solution, including: adding ammonia water or water to the sucrose-6-carboxylate chlorination reaction solution to obtain a mixture, and subjecting the mixture to preliminary neutralization reaction; introducing an ammonia gas into a resulting reaction solution at a predetermined temperature, adjusting a pH of the resulting reaction solution to a predetermined alkalinity range, and conducting a reaction at a reaction temperature for a period of time; and adjusting a pH of a reaction solution obtained after the ammonia gas neutralization using an acid to a predetermined acidity range.

Abstract: The present disclosure provides an apparatus for implementing User Plane Function, UPF. The apparatus includes: a Field Programmable Gate Array, FPGA, configured to forward user plane data between a terminal device and a server; and a processor connected to the FPGA and configured to receive control information from a core network and transfer the control information to the FPGA for controlling the forwarding of the user plane data.
