摘要： A multi-user flexible Ethernet fine granularity time slot allocation method and apparatus. The method is specifically: providing two time slot resource allocation and deployment schemes according to user demands, where the first scheme performs time slot allocation based only on an objective of global minimization of jitter of time slot allocated to all the users and can improve resource allocation equity and improve whole performance of a network. The second scheme performs weighted sum of delay and jitter minimization based time slot allocation on each user according to the quantity of time slots required for the users in sequence from large to small on the premise of most user input data in the current time slot assignment period being transmitted in the current time slot assignment period.

摘要： Disclosed is a two-phase access authentication method integrating spatial-temporal features in space-air-ground integrated networks. In the method, an access authentication is divided into two phases: a primary authentication phase and a continued authentication phase. In the primary authentication phase, a user equipment and a satellite are respectively initialized and registered through a ground network control center. In the authentication phase, a fast and secure access is achieved by using a user ID, facial features, and other authentication factors. In the continued authentication phase, data of a user flow and behavior features are acquired, and feature comparison is performed by using historical user data; and a security level and an authentication decision are output. According to the disclosure, the spatial-temporal features are integrated to perform access authentication on a satellite-ground communication network, the authentication not only achieves a fast access, but also continuously ensures the system security in a service phase.
