摘要： This application relates to a communication method and apparatus. The method includes: determining that content of a to-be-sent second data packet is the same as content of a first data packet, where the second data packet is a data packet following the first data packet; and sending repetition indication information, where the repetition indication information indicates that the second data packet is a data packet that repeats a previous data packet. If the content of the to-be-sent second data packet is the same as the content of the first data packet sent last time, the repetition indication information is sent instead of sending the second data packet. In this way, a receiving end can determine the content of the second data packet (which is the same as the content of the first data packet received last time) indicated by the repetition indication information. In addition, because the second data packet does not need to be sent, transmission resources can be saved, and a capacity of a 5GS can be increased.

摘要： Embodiments of this application provide a wireless communication method, a communication apparatus, and a communication system. The method includes: A mobility management network element receives a handover request from a source access network device, where the handover request includes an identifier of a first session, the first session corresponds to a first network slice, and the first session is used to transmit a data packet of a first application; when determining that a target access network device does not support the first network slice, determines a second network slice supported by the target access network device; and triggers the target access network device to transmit the data packet of the first application through the second network slice. In this solution, after a terminal device moves out of coverage of the first network slice, when the target access network device does not support the first network slice corresponding to the first session, the second network slice supported by the target access network device is selected, so that the target access network device transmits, through the second network slice, the data packet of the first application that is originally transmitted in the first session, thereby ensuring service continuity and helping improve user experience.

摘要： A communication method and a communication apparatus are provided. The method includes: A session management function receives indication information from a policy control function (S401), where the indication information indicates the session management function to send an identifier of a user plane function to the policy control function, and the user plane function is configured to transmit data of a first service. The session management function sends the identifier of the user plane function to the policy control function based on the indication information (S402). In this way, the identifier of the user plane function can be sent to the policy control function via the session management function, so that the policy control function can obtain the identifier of the user plane function. This can help implement information exposure of the user plane function.

摘要： This application relates to a communication method, device, and system. A policy control network element receives first information from a first network element, where the first information includes a group identifier and a data type corresponding to the group identifier, the group identifier indicates a group, and the group includes one or more terminal devices. The policy control network element obtains first data based on the first information, where the first data is data corresponding to the data type. In embodiments of this application, the data type obtained by the policy control network element corresponds to the group. Therefore, the data type is applicable to the one or more terminal devices included in the group. By using this solution, it can be ensured that the policy control network element can accurately obtain data corresponding to the group to which the terminal devices belong.

摘要： This application provides a communication method, an apparatus, and a system. The method includes: A policy control network element obtains an application identifier, determines a first application descriptor based on the application identifier, and sends the first application descriptor to a session management network element, where the first application descriptor is for generating an ATSSS rule, and the ATSSS rule includes the first application descriptor. Based on this solution, the policy control network element may determine an application descriptor, and send the application descriptor to the session management network element, so that the session management network element may generate the ATSSS rule based on the application descriptor. In this way, the ATSSS rule is accurately generated, and the method is simple and easy to implement.
