摘要： This application provides a communication method and a communication apparatus. A second access network device receives a first message from a first access network device, where the first message indicates whether a first state of an MBS session is activated or deactivated; and the second access network device sends a first acknowledgment message corresponding to the first message to the first access network device. In this solution, the first message indicates the first state of the MBS session, and the second access network device may determine, based on the first state, whether to request a core network to establish a UP tunnel. If the first state of the MBS session is activated, the second access network device may trigger to newly establish a UP tunnel, to ensure normal transmission of the MBS in a handover process; or if the first state of the MBS session is deactivated, the second access network device may not trigger to newly establish a UP tunnel or may request to newly establish and suspend a UP tunnel, to avoid a resource waste problem.

摘要： This application provides a communication method and apparatus, and relates to the field of communication technologies, to ensure service continuity of an MBS of a terminal device in a cell handover process. The method includes: A first access network device configures, as a second radio bearer that is used to carry a unicast service, a first radio bearer that is currently used to carry an MBS between the first access network device and a terminal device. The first access network device sends the MBS to the terminal device in a unicast mode through the second radio bearer. In this way, in a process in which the terminal device is subsequently handed over to a second access network device, the first access network device and the second access network device directly switch an MBS, that is being transmitted, to the second access network device in a current unicast service switching manner. This resolves a disruption of the MBS caused because the second access network device does not support a multicast and broadcast transmission mode.

摘要： This application provides a communication method and a communication apparatus. The method includes: A central unit determines a first transmission mode of a first service, where the first transmission mode is a point-to-point transmission mode or a point-to-multipoint transmission mode. The central unit indicates a distributed unit to transmit a first data packet of the first service in the first transmission mode. This can improve reliability of transmitting first service data.

摘要： A quality of service QoS parameter processing method and network element, a system, and a storage medium are disclosed. The method includes: obtaining, by a control plane network element, a first QoS parameter between a terminal device and a user plane function network element; and obtaining capability information of a first network domain, determining a second QoS parameter of the first network domain based on the capability information of the first network domain and the first QoS parameter, and sending first information of the second QoS parameter to the first network domain. The first network domain includes at least one of a radio access network, a backhaul network, and a user plane function network element. This solution can improve data packet scheduling accuracy and user experience.

摘要： An operation method for an electronic device and an electronic device are provided, and relate to the field of electronic devices. In a split-screen display scenario, a function of quickly opening a specific interface by using an entered gesture is implemented. When a screen of the electronic device is split for display, the electronic device receives different operations for a side that is of a single window and that is closely adjacent to another window, and the electronic device may execute a corresponding event only for the window, for example, display a previous-level interface of a current interface in the window, display a desktop in the window, or display a task list interface in the window, and an interface displayed in the another window remains unchanged.

摘要： Embodiments of this application disclose an always on display control method and a terminal device. The control method is applied to a terminal device having a display. First, the terminal device obtains meteorological information of a target area in a current periodicity. Then, the terminal device determines corresponding to-be-displayed information based on the obtained meteorological information, and further determines a display attribute of a target object based on the to-be-displayed information, where the to-be-displayed information is used to reflect the meteorological information, the display attribute of the target object includes a color and/or brightness, and the target object includes information displayed on the display by the terminal device in an always on display state. Finally, the terminal device displays, on the display in the always on display state, the target object whose display attribute is determined.

摘要： This application discloses an application instance address translation method, including: sending, by a control plane device, a collaboration request to a mobile edge cloud MEC control device, where the collaboration request includes location information of a terminal and information about an application service; receiving, by the control plane device, response information from the MEC control device, where the response information includes an address of a target instance; and sending, by the control plane device based on the address of the target instance, the address of the target instance to a first user plane device corresponding to the target instance, and instructing the first user plane device to set, as the address of the target instance, a forwarding address of an uplink packet sent by the terminal to obtain the application service. In this case, after performing cross-access node service area movement, the UE can directly perform packet exchange without recreating a service connection to a new application instance. This reduces a network delay.
