Method, device, and system for identifying traffic type across devices

A service control device, comprising:

• a memory;
• a processor coupled to the memory and configured to:
• obtain flow identification information of a service flow transmitted between a user equipment and a network, wherein the flow identification information is used for the service control device to identify a traffic type of the service flow when the service control device is a source traffic control device;
• and
• synchronize the obtained flow identification information to a target service control device when detecting that the user equipment is handed over from the service control device to the target service control device,
• wherein the target service control device identifies, according to the flow identification information, the traffic type of the service flow transmitted between the user equipment and the network,
• wherein the flow identification information includes packet statistics information of the service flow transmitted between the user equipment and the network and triplet information of the service flow transmitted between the user equipment and the network,
• wherein the packet statistics information includes uplink and downlink directions of packets in the service flow transmitted between the user equipment and the network and the number of packets, and
• wherein the triplet information includes Internet Protocol (IP) information, port information, and transport layer protocol type of the transmitted service flow.

A system for identifying a traffic type across devices, comprising:

• a source service control device;
• a target service control device;
• and
• a user equipment,
• wherein the user equipment is configured to transmit a service flow with a network through the source service control device,
• wherein the source service control device is configured to:
• obtain flow identification information of the service flow transmitted between the user equipment and the network when the user equipment transmits the service flow with the network through the source service control device, wherein the flow identification information is used for the source service control device to identify a traffic type of the service flow;
• and
• synchronize the obtained flow identification information to the target service control device when detecting that the user equipment is handed over from the source service control device to the target service control device, and
• wherein the target service control device is configured to identify, according to the flow identification information, the traffic type of the service flow transmitted between the user equipment and the network,
• wherein the flow identification information includes packet statistics information of the service flow transmitted between the user equipment and the network and triplet information of the service flow transmitted between the user equipment and the network,
• wherein the packet statistics information includes uplink and downlink directions of packets in the service flow transmitted between the user equipment and the network and the number of packets, and
• wherein the triplet information includes Internet Protocol (IP) information, port information, and transport layer protocol type of the transmitted service flow.
