Abstract: A quality of service processing method and apparatus and a communication system are provided. The method provides a session management network element receives a first rule from a policy control network element, where the first rule includes direction information and quality of service notification control information. The direction information indicates a direction of a first service flow. The session management network element sends the direction information and the quality of service notification control information to an access network device, and receives quality of service notification information in a first direction from the access network device, and sends the first direction and information about the first service flow to the policy control network element. According to the method, quality of service of a service flow can meet corresponding target quality of service while reducing signaling interaction in a quality of service processing process.

Abstract: A session migration method includes sending, by a transmission management apparatus, registration request cancellation information to a subscriber information management apparatus in response to user plane security enforcement information of a packet data unit (PDU) session failing to match user plane encryption protection information of an evolved packet system (EPS). The registration request cancellation information is useable to indicate that the PDU session fails to support migration to the EPS, and the PDU session has been registered with the subscriber information management apparatus.

Abstract: The present disclosure relates to user plane information reporting methods and apparatus. In one example method, a session management network element obtains parameter information, and initiates establishment of a dedicated tunnel between a first communications apparatus and a second communications apparatus, where the parameter information indicates the first communications apparatus to report user plane information when a reporting condition is met. The session management network element sends a first rule to the first communications apparatus, where the first rule indicates the first communications apparatus to send a packet to the second communications apparatus through the dedicated tunnel when the reporting condition is met.

Abstract: 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: A communication method, apparatus and system are provided. The method includes: A first network element receives, from an application function network element, a first request for requesting to obtain information about a first policy control network element, where the first policy control network element is a policy control network element that provides mobility management.
The first network element sends the information about the first policy control network element to the application function network element. Based on this solution, the application function network element obtains the information about the first policy control network element from the first network element, and the application function network element may further send input information to the first policy control network element, so that the first policy control network element can select, based on the input information, an AM policy that matches a requirement of a currently running application.
