FIG. 1 is a schematic flowchart of a communication method 100 according to an embodiment of the present application. As shown in FIG. 1, the communication method 100 includes 110, 120, 130 and 140.

At 110, the transmitting side adds time-indicating information to the transmitting packet, and the time-indicating information is used by the receiving side to acquire a delay from the transmitting side to the receiving side.

Selectably, the transmitted packet may be a packet data aggregation protocol (PDCP) layer packet, a radio link control (RLC: Radio Link Control) layer packet, or a media access control (MAC: Media Access Control) layer packet. is there.

Optionally, the transmit packet is a data packet or a dedicated delay detection packet.

At 120, the transmitting side transmits the transmitting packet to the receiving side.

Selectably, the transmitting side determines that it is necessary to acquire the service quality (Quality of Service) of the service corresponding to the delay from the transmitting side to the receiving side, and according to the corresponding service quality QoS. The transmitting side transmits the transmitting packet to the receiving side.

At 130, the receiving side receives the transmission packet transmitted from the transmitting side, and the transmitting packet contains the time instruction information.

Here, the receiving side analyzes the time instruction information in the same layer where the time instruction information is added by the transmitting side. For example, when the transmitting side adds the time instruction information to the MAC layer, the receiving side is in the MAC layer. Analyze time indication information.

The delay from the transmitting side to the receiving side can be determined based on the difference between the end time of processing and the start time. Here, the start time when the transmitting side processes the transmitted packet refers to the time when the packet is obtained or the time when the packet starts to be generated, and the end time when the receiving side processes the transmitted packet refers to the time when the packet is analyzed. Can be done.

Selectably, the start and end times may be absolute times, such as Coordinated Universal Time (UTC), absolute time corresponding to Hokuto and GPS, and therefore the difference between the end and start times. Can be used directly as a delay from the sender to the receiver.

The start and end times may not be absolute times, and may be, for example, the time defined in the communication system, eg, the time indicated in a subframe or time slot, and thus the simultaneous time of the sender and receiver. It is necessary to determine the delay from the transmitting side to the receiving side based on the deviation and the difference between the end time point and the start time point.

Here, the synchronization time deviation between the transmitting side and the receiving side may be calculated based on the synchronization time deviation between any two nodes from the transmitting side to the receiving side. Among them, when the node before the intermediate node is not synchronized with the intermediate node, the node can determine the synchronization time deviation with the previous node and record the synchronization time deviation in the transmission packet.

For example, from the transmitting side to the receiving side, it is necessary to pass through the node 1 and the node 2. Therefore, after the node 1 receives the transmission packet, the synchronization time deviation between the transmitting side and the node 1 is acquired and recorded in the transmitting packet. After receiving the transmission packet, node 2 can acquire the synchronization time deviation between node 1 and node 2 and record it in the transmission packet, where the synchronization time between node 1 and node 2 can be obtained. The deviation can be integrated with the previous synchronization time deviation and recorded in the transmitted packet, that is, the synchronization time deviation between node 1 and node 2 and the previous synchronization time deviation are added to obtain the recorded synchronization time deviation. It may be changed to the added synchronization time deviation, or the synchronization time deviation between the node 1 and the node 2 may be recorded individually in one information field, and the receiving side receives the transmission packet and then the node 2 and the node 2. The synchronization time deviation with the receiving side can be acquired, and the synchronization time deviation between the transmitting side and the node 2 can be acquired based on the recording of the transmission packet, thereby acquiring the synchronization time deviation between the transmitting side and the receiving side. be able to.

Optionally, the sender can add a processing delay to the transmit packet to process the transmit packet, and the intermediate node adds the processing delay and the transmission delay with the previous node to the transmit packet after receiving the transmit packet. It can be added, in which the intermediate node can record the processing delay and transmission delay individually in different information fields of the transmitted packet, or the intermediate node can record the processing delay and transmission delay obtained by that node. Can be recorded in the information field, but without adding to the time recorded by other nodes, or the intermediate node adds the processing delay and the processing delay obtained by other nodes to one piece of information. The transmission delay and the transmission delay obtained by another node can be recorded in another information field, or the intermediate node can record the sum of the transmission delay and the processing delay and the processing delay recorded by the transmitted packet. And the sum of the transmission delays are added to update the record. After receiving the transmission packet, the transmission side can obtain a delay between the transmission side and the reception side in response to the instruction of the time instruction information of the transmission packet.

In order to facilitate understanding, some modes of recording time instruction information will be described below with some embodiments.

In one embodiment, the time indication information is a processing delay in which the transmitting side processes the transmitted packet, a processing delay in which any intermediate point from the transmitting side to the receiving side processes the transmitted packet, and an arbitrary intermediate node. Includes the transmission delay with the previous node acquired by, where the processing delay for processing the transmitted packet by different nodes is included in the different information fields of the transmitted packet, and the transmission delay acquired by different nodes It is included in different information fields of the transmitted packet, and the processing delay and transmission delay of the same node are included in the different information fields of the transmitted packet. In this case, the receiving side determines the processing delay in which the receiving side processes the transmitted packet, and the transmission delay between the receiving side and the node in front of the receiving side, and the transmitting side processes the transmitted packet. The processing delay for the intermediate node to process the transmitted packet, the transmission delay with the previous node acquired by any intermediate node, the processing delay for the receiving side to process the transmitted packet, and the receiving side and before the receiving side. Based on the sum of the five parties, the transmission delay with the node, the delay from the transmitting side to the receiving side is determined.

For example, it is necessary to pass from the transmitting side to the receiving side via node 1 and node 2, the processing delay (1 ms) for processing the transmitted packet by the transmitting side is recorded in the information field, and the node 1 receives and transmits the transmitted packet. The transmission delay of 0.5 ms from the side to the node 1 and the processing delay of 1 ms for processing the transmission packet are acquired, 0.5 ms and 1 ms are recorded in different information fields, respectively, and the node 2 receives the transmission packet and the node The transmission delay of 0.6 ms from 1 to node 2 and the processing delay of 1.1 ms for processing the transmission packet are acquired, and the 0.6 ms and 1.1 ms are recorded in different information fields, respectively, and the receiving side transmits the transmission. The packet is received, the transmission delay of 0.4 ms from the node 2 to the receiving side and the processing delay of 1.2 ms for processing the transmitted packet are acquired, and the 1 ms, 1 ms, 0.5 ms, 0. The time value obtained by acquiring 6 ms and 1.1 ms and adding 1 ms, 1 ms, 0.5 ms, 0.6 ms, 1.1 ms, 0.4 ms, and 1.2 ms is used to determine the delay from the transmitting side to the receiving side.

In one embodiment, the time indication information includes a processing delay in which the transmitting side processes the transmitted packet, a processing delay in which any intermediate node from the transmitting side to the receiving side processes the transmitted packet, and a previous node. The sum of the processing delay for processing the transmission packet by different nodes and the acquired transmission delay is included in the different information fields of the transmission packet. In this case, the receiving side determines the processing delay in which the receiving side processes the transmitted packet and the transmission delay between the receiving side and the node in front of the receiving side, and the transmitting side determines the processing delay in processing the transmitted packet. The sum of the processing delay of processing the transmitted packet by any node from the transmitting side to the previous node of the receiving side and the transmission delay with the acquired previous node, the processing delay of the receiving side processing the transmitted packet, And the delay from the transmitting side to the receiving side is determined based on the sum of the four parties, that is, the transmission delay between the receiving side and the node in front of the receiving side.

For example, it is necessary to pass from the transmitting side to the receiving side via node 1 and node 2, the processing delay (for example, 1 ms) for the transmitting side to process the transmitted packet is recorded in the information field, and the node 1 receives the transmitted packet and transmits it. The transmission delay of 0.5 ms from the side to the node 1 and the processing delay of 1 ms for processing the transmission packet are acquired, 1.5 ms is recorded in the information field, the node 2 receives the transmission packet, and the transmission packet is received from the node 1 to the node 2. The transmission delay of 0.6 ms and the processing delay of 1.1 ms for processing the transmission packet are acquired, 1.7 ms is recorded in an information field different from that of the transmission side, and the reception side receives the transmission packet from the node 2. The transmission delay of 0.4 ms to the receiving side and the processing delay of 1.2 ms for processing the transmitted packet are acquired, and the 1 ms, 1.5 ms, and 1.7 ms recorded in the transmitted packet are acquired, and 1 ms and 1.5 ms are acquired. The time value obtained by adding 1.7 ms, 0.4 ms and 1.2 ms is used to determine the delay from the transmitting side to the receiving side.

Includes the sum of the transmission delay with the previous node. The receiving side determines the processing delay for the receiving side to transmit the transmitting packet and the transmission delay from the node in front of the receiving side to the receiving side, and the transmitting side included in the time instruction information processes the transmitting packet. The sum of the processing delay to be processed, the processing delay for the intermediate node from the transmitting side to the receiving side to process the transmitted packet, and the transmission delay with the previous node acquired by an arbitrary intermediate node, and the receiving side is the transmitting side. The delay from the transmitting side to the receiving side is determined based on the sum of the processing delay for processing the packet and the transmission delay from the node in front of the receiving side to the receiving side.

For example, from the transmitting side to the receiving side, it is necessary to pass through the node 1 and the node 2, the processing delay (for example, 1 ms) for the transmitting side to process the transmitted packet is recorded in the information field, and the node 1 receives the transmitted packet. The transmission delay of 0.5 ms from the transmitting side to the node 1 and the processing delay of 1 ms for processing the transmitted packet are acquired, the 1 ms recorded by the transmitting side is updated to 2.5 ms, and the node 2 receives the transmitted packet. , The transmission delay of 0.6 ms from node 1 to node 2 and the processing delay of 1.1 ms for processing the transmitted packet are acquired, the 2.5 ms recorded by the node 1 is updated to 4.2 ms, and the receiving side receives. 2. Receives the transmission packet, acquires a transmission delay of 0.4 ms from the node 2 to the receiving side and a processing delay of 1.2 ms for processing the transmission packet, and acquires 4.2 ms recorded in the transmission packet. The time value obtained by adding 2 ms, 0.4 ms and 1.2 ms is used to determine the delay from the transmitting side to the receiving side.

If the processing delay and / or transmission delay acquired by each node is not obtained by absolute time, it is necessary to acquire the synchronization time deviation between the transmitting side and the receiving side, among which the transmitting side and the receiving side The synchronization time deviation may be calculated based on the synchronization time deviation between any two nodes from the transmitting side to the receiving side. Here, when the node before the intermediate node is not synchronized with the intermediate node, the node can determine the synchronization time deviation with the previous node and record the synchronization time deviation in the transmission packet.

Here, each node may record the transmission packet individually or in combination with the processing delay and / or the transmission delay when recording the synchronization time deviation with the previous node.
