摘要： A communication method and a communications apparatus are provided. In the method, in a process in which at least one quality of service flow is handed over from a first access network device to a second access network device, the first access network device sends first information to the second access network device, where the first information is used to indicate that the first access network device has notified a core network device that a quality of service requirement of the at least one quality of service flow cannot be met; and after receiving the first information sent by the first access network device, the second access network device may send second information to the core network device, where the second information is used to notify the core network device that a quality of service requirement of a first quality of service flow in the at least one quality of service flow can be met, and the first quality of service flow is a quality of service flow that has been handed over from the first access network device to the second access network device. In this way, notification control statuses that are of the quality of service flow and that are recorded on a core network side and on an access network side after a handover of the quality of service flow can be synchronized with each other as much as possible.

摘要： Embodiments of this application provide a communication method, apparatus, and system. The solution includes: A network device sends transport network information to a policy control network element; and the policy control network element formulates a control policy based on the transport network information, and sends the control policy to the network device, so that the network device correspondingly adjusts a service mode based on the control policy, thereby avoiding affecting data transmission efficiency and reliability because of a mismatch between a used service mode and a current transport network during end-to-end data transmission, and improving the data transmission efficiency and reliability.

摘要： Embodiments of this application provide an uplink PDR generation method, an apparatus, and a system, to resolve a problem in a conventional technology that an uplink data packet may be discarded because a PCF network element may not include uplink SDF information when generating a PCC rule including an RQC indication. The method includes: A session management network element receives a first policy and charging control PCC rule from a policy control network element, where the first PCC rule includes downlink service data flow SDF information that corresponds to a first service. When the first PCC rule includes a reflective quality of service control RQC indication, the session management network element generates, according to the first PCC rule, a first uplink PDR that corresponds to the first service. The session management network element sends, to a user plane network element, the first uplink PDR that corresponds to the first service.

摘要： A user plane information reporting method and an apparatus are provided. The method includes: obtaining, by a session management network element, parameter information, and initiating, by the session management network element, establishment of a dedicated tunnel between a first communications apparatus and a second communications apparatus, where the parameter information is used by the session management network element to indicate the first communications apparatus to report user plane information when a reporting condition is met; and sending, by the session management network element, a first rule to the first communications apparatus based on the parameter information, where the first rule is used to indicate the first communications apparatus to send a packet to the second communications apparatus through the dedicated tunnel when the reporting condition is met. According to the foregoing method, the session management network element may use the first rule to indicate the first communications apparatus to send the packet to the second communications apparatus through the dedicated tunnel when the reporting condition is met. The second communications apparatus only needs to detect whether the packet is received through the dedicated tunnel, to determine reporting of the user plane information, thereby simplifying a logical function of the second communications apparatus.
