Abstract
This application discloses a multicast transmission method. The multicast transmission method includes: a first network device receives a first data packet and first indication information, where the first indication information indicates a sequence of the first data packet in at least one data packet; the first network device sets a sequence number of a first protocol layer of the first data packet based on the first indication information; and the first network device sends the first data packet to a terminal device. In this way, all data packets received by the terminal device include corresponding sequence numbers of the first protocol layers.
Claims21
A multicast transmission method, comprising:
- receiving, by a first network device, a first data packet and first indication information, wherein the first indication information indicates a sequence of the first data packet in at least one data packet;
- setting, by the first network device, a sequence number of a first protocol layer of the first data packet based on the first indication information, wherein the first protocol layer is different from a packet data convergence protocol (PDCP) layer;
- and
- sending, by the first network device, the first data packet to a terminal device.
A multicast transmission method, comprising:
- receiving, by a terminal device, a first data packet, wherein a sequence number of a first protocol layer of the first data packet is set based on first indication information, the first protocol layer is different from a packet data convergence protocol (PDCP) layer, and the first indication information indicates a sequence of the first data packet in at least one data packet;
- and
- processing, by the terminal device, the first data packet based on the sequence number of the first protocol layer.
An apparatus, comprising:
- one or more processors;
- and
- one or more non-transitory computer readable memories coupled to the one or more processors and storing programming to be executed by the one or more processors, the programming including instructions that, when executed by the one or more processors, cause the apparatus to perform:
- receiving a first data packet and first indication information, wherein the first indication information indicates a sequence of the first data packet in at least one data packet;
- setting a sequence number of a first protocol layer of the first data packet based on the first indication information, wherein the first protocol layer is different from a packet data convergence protocol (PDCP) layer;
- and
- sending the first data packet to a terminal device.
