Abstract: Embodiments of this application disclose a request processing method and a corresponding entity, to control a data notification and signaling that is used for triggering paging, thereby avoiding overload of a network element in a core network. The request processing method includes: determining, by an AMF, a first control plane function entity for a terminal device; determining, by the AMF, that the terminal device enters an idle state; obtaining, by the AMF, a first reachability service invocation request from the first control plane function entity; and rejecting, by the AMF, the first reachability service invocation request when the AMF determines, based on the first reachability service invocation request, that a reachability service invocation limitation condition is satisfied.

Abstract: A system and method for controlling a system that includes fixed speed and variable speed compressors are described. The method generally allows the system, for example, a heating, ventilating, and air condition (HVAC) system that includes fixed speed and variable speed compressors, to maximize unit modulating capability. The method allows the use of a variable speed compressor that is relatively smaller, which can lead to cost savings, easier installation, manufacturing, etc.

Abstract: A refrigerant system includes a controller that enables the system to dehumidify the air in a room without relying on a humidistat and without having to operate the system's compressor and electric heater at the same time. To dehumidify the air, the system's compressor, supply air fan, and outside air damper are controlled in a manner similar to other systems operating in a cooling mode when the room temperature is above a certain setpoint temperature. When the room temperature falls below the setpoint, however, the operation changes significantly. The controller closes the outside air damper, decreases the speed of the fan, and continues operating in this manner until the room temperature decreases to a subcooling temperature limit. The subcooling temperature limit is less than a predetermined limit that is used during the system's normal cooling mode.
