Embodiments of this application provide a tracking area selection method, a device, and a system, to resolve a problem of a failure in accessing a network slice by a terminal. The method includes: A mobility management network element initiates an authentication and authorization procedure for a network slice on which authentication and authorization are to be performed and that is in a network slice requested by a terminal; determines, based on a result of the authentication and authorization procedure, identification information of a network slice that the terminal is allowed to access; obtains, based on first information (for example, identification information of the network slice requested by the terminal or identification information of a network slice that the terminal is rejected to access) and the identification information of the network slice that the terminal is allowed to access, identification information of a target network slice and radio resource information corresponding to the target network slice; and sends the identification information of the target network slice and the radio resource information corresponding to the target network slice to an access network device, so that the access network device triggers, based on the identification information of the target network slice and the radio resource information corresponding to the target network slice, the terminal to successfully access a network slice supported by a new TA.

The present invention belongs to the technical field of integrated sensors and is a silicon-based multi-dimensional integrated sensor array used for cleaning the ship's side. The array comprises an optical fiber gyroscope, an electrical conductivity-temperature sensor, an aluminum oxide humidity sensor and a pressure sensor which are arranged on a silicon-based substrate in sequence from top to bottom. The optical fiber gyroscope and the electrical conductivity-temperature sensor, the electrical conductivity-temperature sensor and the aluminum oxide humidity sensor, and the aluminum oxide humidity sensor and the pressure sensor are bonded by using silicon-based bonding technology. By using silicon-based bonding technology, different types of sensors can be integrated on the same silicon-based platform to achieve high integration. The multifunctionality enables the integrated system to simultaneously monitor different physical quantities, such as angular velocity, electrical conductivity, humidity, pressure and temperature.

This invention discloses a control method and system for the working mode of batteries in a battery swapping station. The battery swapping station includes an in-station monitoring platform and several sets of corresponding chargers and charging compartments. Each charger in each set is communicatively connected to the battery pack installed in the charging compartment. The in-station monitoring platform is also communicatively connected to each charger. The control method includes the following steps: the in-station monitoring platform sends a power-on command to the corresponding charger; upon receiving the power-on command, the charger controls the battery pack in the corresponding charging compartment to be powered on at low voltage; the in-station monitoring platform responds to the charging start command by sending a first message to the charger; upon receiving the first message, the charger forwards the first message to the battery pack in the corresponding charging compartment; and upon receiving the first message, the battery pack enters the battery swapping station charging mode. This invention simplifies the structural design of the battery swapping station, reduces costs, and ensures good DC charging of the batteries within the station.
