A failure rate for data packets is an index of QoS guarantee, which is generally used for identifying the failure of a single data packet. In some new scenes (for example, XR scenes), a new QoS index and a data set (for example, frame-level) failure rate require to be considered. A data set may include a plurality of data packets. The success and failure situations of the individual data packets may be different. In view of some data packets being delivered successfully and some data packets failing to be transmitted in a data set, how to determine whether the data set is failed or successful is a problem to be solved. Hereinafter, a problem will be described using a PDU Set (protocol data unit set) as a data set.
Embodiments of the present invention provide a data processing method and a communication device, which are intended to solve the problems of how to determine the success of data sets and/or how to determine the failure of the data sets.
In a scene, all PDUs in the PDU Set or all data packets in the PDU Set are not completely transmitted. At this moment, the PDU Set is considered to fail to be transmitted. In addition, there are other failure scenes for the PDU Set:
Scene 1: Since a PDU Set may have a plurality of data packets, the data packets are sent to a receiver one by one. It is possible that packet 1 and packet 2 are successfully sent before packet 3 is failed (transmission failure or timeout).
If the PDU Set is a PDU Set in which all data packets require to be completely processed, the PDU Set is determined to be a failed PDU Set in a case that some packets fail to be transmitted.
If not all data packets in the PDU Set require to be completely processed, the PDU Set in which some data packets are delivered successfully may be determined to be a successful PDU Set.
If header data packets in the PDU Set require to be completely processed, the PDU Set in which the header data packets are delivered successfully while other data packets are failed in transmission may be determined to be a successful PDU Set.
If tail data packets in the PDU Set allow to be lost, the PDU Set in which the tail data packets are failed while other data packets are delivered successfully may be determined to be a successful PDU Set.
In one solution, a communication device (for example, a RAN) may obtain: 1) an indicator that all data packets in the PDU Set require to be completely processed; 2) an indicator that header data packets in the PDU Set require to be completely processed; and 3) an indicator that tail data packets in the PDU Set allow to be lost, so as to determine whether the PDU Set in which some data packets are successful while some data packets are failed is a successful PDU Set or a failed PDU Set.
For a better illustration, a PDU Set is mapped by a frame:
Scene 1.1: An I frame includes 100 packets, where the I frame is mapped to a PDU Set, and the PDU Set also has 100 packets. The first 30 packets are delivered successfully to a UE, and the 31st packet has a transmission failure or transmission timeout (exceeding a PDU Set delay budget).
Based on the indicator that all data packets in the PDU Set require to be completely processed, the RAN is required to discard the subsequent packets since the 31st packet is failed. At this moment, the PDU Set should be a failed PDU Set.
In the absence of the indicator that all data packets in the PDU Set require to be completely processed, the PDU Set may be a successful PDU Set.
Based on the indicator that tail data packets in the PDU Set allow to be lost and in a case that the range of tail data is 32-100, the PDU Set may be a successful PDU Set.
Scene 1.2: The PDU Set also has 100 packets. The first packet is failed in sending, and the RAN discards the subsequent 99 packets based on the indicator that all data packets require to be completely processed or the indicator that header data packets require to be completely processed. In this way, all data packets in the PDU Set are not sent. The PDU Set should be a failed PDU Set.
Scene 1.3: The PDU Set also has 100 packets. The first 99 packets are successfully sent, and the 100th packet is failed (sending failure or timeout).
Based on the indicator that all data packets in the PDU Set require to be completely processed, the PDU Set should be a failed PDU Set.
Based on the indicator that tail data packets in the PDU Set allow to be lost, the PDU Set may be a successful PDU Set.
Except for transmission failure and timeout scenes, the communication device (for example, the RAN) may find that some data packets in the PDU Set are lost or the PDU Set is lost entirely after receiving the data packets in the PDU Set.
Scene 2: Some packets in the PDU Set received from N3 are lost.
At this moment, there are many processing modes:
If it is considered that a PDU Set failure rate is a failure rate which cannot be exceeded based on the guarantee of the RAN, the loss of a packet by N3 is obviously not the responsibility of the RAN and should not be incorporated into failure rate statistics of the PDU Set.
If it is considered that the PDU Set failure rate is a failure rate to be guaranteed by 5GS, the loss of a packet in N3 is obviously the responsibility of 5GS and should be incorporated into failure rate statistics.
Scene 3: Before mapping a PDU Set, a UPF finds that the 31st packet of a data unit received from N6 is lost, resulting in the transmission failure of the PDU Set. At this moment, the failure is not the responsibility of 5GS and should not be incorporated into failure rate statistics. For such a PDU Set, the UPF sends an indicator. The RAN may distinguish between scene 2 and scene 3. Then, scene 4 is excluded, and the PDU Set in scene 3 is not incorporated into failure rate statistics.
For a scene where a data unit is lost entirely, the PDU Set skips such a data unit when assigning sequence numbers, and therefore, the scene is naturally excluded.
For a scene where some data packets in the data unit are lost, the mapped PDU Set has a sequence number.
Another solution is that the UPF makes statistics on a loss rate or loss number of the PDU Set. The RAN subtracts the loss rate of the PDU Set or subtracts the loss number of the PDU Set when making statistics on the failure rate.
