Abstract: An indoor occupancy distribution analysis system is provided, which includes a base station and a network management device that communicate with each other. The base station is configured to collect performance indicators corresponding to each user equipment from the base station. The performance indicators are associated with the communication between the user equipment and the base station. The network management device is configured to receive these performance indicators, input them into a classifier, obtain the inference result output by the classifier, and derive occupancy distribution from the inference result.

Abstract: A method for secure data transmission is provided. The method includes requesting a key from an encryption and decryption application in a near real-time radio access network (RAN) intelligent controller (Near-RT RIC). The method includes receiving the key from the encryption and decryption application. The method includes encrypting data by using the key, and generating encrypted data. The method includes storing the encrypted data to a database in the Near-RT RIC through a shared data layer.
