  • Patent number: 12127075
    Abstract: In a method of real-time network monitoring and location updating, a location report is received by an unmanned aerial system application enabler (UAE) server from a location management (LM) server. The location report indicates location information of a user equipment (UE). A first network event notification associated with the UE is received by the UAE server from a network resource management (NRM) server. The first network event notification indicates a connection status of the UE with a network. In response to detecting a re-connected status of the UE, a second networking event notification is received by the UAE server from the NRM server. The second networking event notification indicates that the UE reconnects to the network. Further, (i) the second networking event notification, (ii) an identity of the UAE server, and (iii) most recently updated location information of the UE from the LM server are recorded by the UAE server.

  • Publication number: 20240333953
    Abstract: In a method of decoding, a first flag of a sequence parameter set (SPS) that is referred to by a current picture is obtained. The current picture is decoded based on whether the first flag indicates the reference picture resampling is enabled. The first flag equal to a first value indicates that the reference picture resampling is enabled and the current picture is allowed to include slices that refer to a reference picture with at least one of a different spatial resolution or a different scaling window in an active entry of a reference pictures list. The first flag equal to a second value indicates that the reference picture resampling is disabled and no slice of the current picture refers to the reference picture with the at least one of the different spatial resolution or the different scaling window in the active entry of the reference picture list.
