Abstract: A service implementation method, apparatus, and system are disclosed. The service implementation method includes: receiving, by a serving gateway, a data packet of a terminal device sent by a packet data network gateway; if the data packet is a data packet with a serving priority and the serving gateway has sent a paging trigger message with a serving priority to a mobility management element, skipping, by the serving gateway, sending a paging trigger message to the mobility management element; or if the data packet is a data packet with a serving priority and the serving gateway has sent no paging trigger message with a serving priority to a mobility management element, sending, by the serving gateway, a paging trigger message to the mobility management element; wherein the paging trigger message is used to enable the mobility management element to page the terminal device.

Abstract: Embodiments of this application provide a packet transmission method, a communication apparatus, and a communication system. A target transport layer proxy network element establishes a fourth transport layer connection based on a first context of a source transport layer proxy network element, where the first context is a context about packet transmission of the source transport layer proxy network element on a first path. If the target transport layer proxy network element receives first indication information, and the first indication information indicates that application context migration between a first application server and a second application server is completed, the target transport layer proxy network element performs transport layer processing on a packet on a second path based on a second context of the target transport layer proxy network element, and transmits, on the second path, a packet obtained through the transport layer processing. Hence, a packet loss can be avoided.

Abstract: The present disclosure relates to quality of service (QoS) information notification methods, devices, and systems. In one example method, a user plane network element obtains a first QoS notification, where the first QoS notification includes first QoS information used to indicate QoS of a target service. The user plane network element sends first indication information to an application network element to which a QoS notification needs to be reported, where the first indication information is used to indicate a second QoS notification, the second QoS notification includes second QoS information of the target service, and the first QoS notification is the same as the second QoS notification, or the second QoS notification is determined based on the first QoS notification.

Abstract: A communication method includes: determining a first central unit (CU)-user plane (UP) and a user plane function (UPF) network element that correspond to a quality of service (QoS) flow, where an access network device to which the first CU-UP belongs supports at least two CU-UPs; determining a first packet delay budget (PDB) for transmitting the QoS flow between the first CU-UP and the UPF network element; and sending the first PDB to the access network device, where the first PDB is used by the access network device to schedule an air interface resource. After the CU-UP corresponding to the QoS flow is determined, the PDB of the CU-UP corresponding to the QoS flow may be sent to the radio access network (RAN) device.
