Abstract: Embodiments of the present disclosure disclose a session management method and an apparatus. The technology is specifically related to sending, by user equipment, a NAS message to an AGF, where the NAS message includes a PDU session establishment request message used to request to establish a PDU session, receiving, by the user equipment, a PDU session establishment accept message returned by a network side device, and establishing, by the user equipment, an access session with the AGF, where the access session is an access session related to the PDU session. The user equipment sends the NAS message to establish the PDU session, and establishes the access session with the AGF. Because the access session is related to the PDU session, the user equipment can map the PDU session to the access session, so that the user equipment accesses a 5G CN through a fixed network

Abstract: This application describes examples of a wireless communication method, a communication apparatus, and a communication system. In one example, the method includes obtaining, by a radio access network device, a first time point at which a downlink data flow of a first application arrives at the radio access network device and a second time point at which a downlink data flow of a second application arrives at the radio access network device. When the first time point and the second time point meet a first condition, the radio access network device determines, based on a load capability of the radio access network device, a third time point at which the downlink data flow of the first application arrives at the radio access network device. The third time point is an adjusted time point at which the downlink data flow of the first application arrives at the radio access network device.

Abstract: A communication method includes receiving, by a terminal device, first clock source information. The first clock source information corresponds to clock source information of a wireless communication system. The first clock source information indicates that a fifth generation (5G) system clock is useable as a clock source. The method further includes sending, by the terminal device, the first clock source information to an adjacent device.

The first interface is an interface between the access gateway device and the user plane function network element. The method further includes receiving, by the user plane function network element, the fixed network packet.

Abstract: Example communication methods and apparatus are described. One example method includes sending a first request message by a terminal device to a first device, where the first request message includes a second identifier identifying that access of the terminal device to a target server is continuous access. The first device sends the first request message to a second device based on the second identifier and a third mapping relationship indicating a correspondence between the second identifier and the second device. The second device sends the first request message to the target server based on the second identifier and a second mapping relationship indicating a correspondence between the second identifier and the target server.
