  • Publication number: 20240080659
    Abstract: The present application relates to the technical field of wireless communications, and discloses a terminal location capability reporting method and device. The method comprises: an access and mobility management function (AMF) entity obtains and stores a terminal location capability of a terminal, and after a location service for a target terminal arrives, if the terminal location capability of the target terminal is stored in the AMF entity, the AMF entity transmits the terminal location capability of the target terminal to a location management function (LMF) entity, so that the LMF sets a location method for the target terminal according to the terminal location capability. In the process above, when the LMF entity needs to obtain the terminal location capability of the target terminal, the terminal location capability of the target terminal can be directly obtained from the AMF entity, and there is no need to interact with the terminal to obtain the terminal location capability.

  • Publication number: 20230104997
    Abstract: An outdoor unit includes a pressure sensor for detecting an internal pressure of a first pipe. An outdoor unit controller is configured to: receive a switching signal; control an outdoor fan and a compressor to operate in a case where the switching signal instructs the outdoor unit to operate, the compressor operating at a first frequency; acquire a current state of the indoor fan in a case where the on signal instructs the outdoor unit to shut down; and control the compressor and the outdoor fan to operate if the current state of the indoor fan is an operating state, the compressor operating at a second frequency. The second frequency is lower than the first frequency. The current state of the indoor fan is obtained according to the internal pressure of the first pipe.
