Abstract: A reflective quality of service QoS method and an apparatus are provided, to implement uplink layered QoS, and implement more refined uplink QoS management. The method includes: A terminal device determines to enable a first reflective QoS manner, and determines a first rule in the first reflective QoS manner. The first rule includes a QoS rule and/or a QoS flow to data radio bearer DRB mapping rule. The terminal device identifies classification information of a packet in the first reflective QoS manner, where the classification information is for distinguishing between packets in a same internet protocol IP flow.

Abstract: A communication method and apparatus are provided for transmitting packets of a data stream between user equipment. After receiving a first packet from a first user equipment, a user plane function (UPF) forwards the first packet to a second user equipment at a first moment, so that the first packet that arrives at the UPF before the first moment is not forwarded to the second user equipment until the first moment, to support deterministic sending and ensure that a time sensitive communication (TSC) packet is sent at a determined moment, so as to provide deterministic delay assurance for applications such as industrial control and telemedicine.

Abstract: A communication method and apparatus are provided, to resolve a problem that a terminal device cannot perform normal communication on other accesses due to an operation performed on common parameters over some accesses of the terminal device. The method includes: When the terminal device on a first access is switched from a first PLMN to a second PLMN, if a state of the terminal device on a second access is that the terminal device is registering with the first PLMN or has registered with the first PLMN, the terminal device determines not to delete a first mobility management parameter on the first access. If a state of the terminal device on a second access is that the terminal device has not registered with the first PLMN, the terminal device determines to delete a first mobility management parameter on the first access.

Abstract: A communication method and a communications apparatus, where the method may include: selecting or re-selecting, by a terminal device, from a first cell to a second cell through cell selection or re-selection, where radio access technologies of the first cell and the second cell are different, and where the terminal device is in an inactive mode in the first cell; re-selecting, by the terminal device, to the second cell through cell re-selection; and initiating, by the terminal device, a registration procedure after completing the cell re-selection. When the terminal device in inactive mode performs cell re-selection based on different radio technologies, the terminal device initiates the registration procedure or a service request procedure, for NAS signaling connection recovery. When the terminal device changes a radio access technology, a network device can update information.

Abstract: A communication method and apparatus includes: A communication device determines at least one first packet in first duration. The at least one first packet belongs to a same PDU set, the first duration is determined based on a first interval or burst duration, the first interval is a time interval at which the communication device obtains two adjacent PDU sets in time domain, and the burst duration is duration of one PDU set. Then, the communication device sends the at least one first packet.
