  • Publication number: 20240334258
    Abstract: The disclosure provides a method for multi-modal service-based cell handover and related devices. A first base station transmits a first message to a second base station. The first message includes device identifier information of multiple terminals and service identifier information of a first multi-modal service. The multiple terminals are terminals in a source cell of the first base station that carry data of the first multi-modal service. The first message is used for the first base station to request the second base station to perform handover preparation. The first base station receives a second message from the second base station. The second message indicates that the second base station completes the handover preparation. The first base station transmits a third message to the multiple terminals. The third message indicates a target cell for handover.

  • Patent number: 11968580
    Abstract: This application provides a reflective QoS flow characteristic-based communications method and apparatus. In the method, an access-network network element sends first information to a core-network network element, where the first information is used to indicate whether a data packet has a reflective QoS flow characteristic; and the access-network network element determines, based on the first information, whether there is a need to send a QoS flow identifier to a terminal. In this way, signaling overheads are reduced.
