Abstract: This application provides a communications method and an apparatus. According to the communications method in this application, a target arrival time point of a first data packet in a QoS flow may be determined, and a waiting delay corresponding to the target arrival time point is less than or equal to a preset threshold. Therefore, according to the method in this application, a queuing delay of a data packet at an access network device or a terminal device can be reduced. In addition, in a process of determining the target arrival time point according to the communications method in this application, a preset requirement of the QoS flow or a preset requirement of a service flow corresponding to the QoS flow is considered. Therefore, according to the method in this application, determining the target arrival time point through a plurality of times of negotiation can be avoided.

Abstract: This application discloses a method for implementing a user plane security policy, an apparatus, and a system. In an implementation, a terminal apparatus may associate or establish a PDU session based on user plane security indication information that is of an application and that is sent by a network device. In another implementation, a PCF adds an obtained user plane security attribute requirement of the application to a PCC rule and sends the PCC rule to an SMF, so that the SMF performs QoS flow binding based on the user plane security attribute requirement. According to the foregoing method, the user plane security attribute requirement of the application can be met.

Abstract: This application provides a method and an apparatus for assigning an EBI. When an EBI needs to be assigned to an EPS bearer to which a QoS flow is mapped in an EPS, whether user plane security enforcement information of a PDU session matches user plane encryption protection information of the EPS is determined, that is, whether a user plane capability of the EPS can meet a user plane security requirement of the PDU session is determined. The EBI is assigned to the EPS bearer only when the requirement is met. Otherwise, the EBI is not assigned to the EPS bearer or the EBI is released if the EBI has been assigned. In this way, when UE moves from a 5GS to the EPS, the EPS bearer is prevented from using an EBI that does not meet the user plane security requirement for data transmission.

Abstract: In an access and mobility management policy association termination method, a first access and mobility management function apparatus sends first policy control function identifier information of a first policy control function apparatus to a second access and mobility management function apparatus, and sends first deletion request information to the first policy control function apparatus. The first deletion request information is for requesting the first policy control function apparatus to delete an access and mobility management (AM) policy association between the first policy control function apparatus and the first access and mobility management function apparatus for a terminal device. Both the first access and mobility management function apparatus and the first policy control function apparatus then delete AM policy control information for the terminal device.
