Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an information processing method, an information processing apparatus, information processing equipment, and a computer-readable storage medium.
Background
The network transmission Time adopts a PTP (Precision Time Protocol) Protocol, which can meet the requirement of high-Precision Time. PTP time synchronization is carried out by adopting a delay calculation mechanism, and the master device and the slave device calculate path delay and time offset between the master device and the slave device by recording timestamps generated during message transmission between the devices, so that time synchronization between the master device and the slave device is realized.
The sending end of each PTP message fills in timestamp information aiming at the sending time of the PTP message, and the receiving end records the timestamp information of a certain PTP message.
In the internal processing process of the device, the sending end generates the PTP message, fills a timestamp of the sending time when the PTP message is ready to be sent, puts the PTP message, and then processes the PTP message through an MAC layer (Media Access Control) or a PHY (physical) layer of the sending interface until the PTP message is really sent. After the time stamp information is sent into the PTP message, the time delay delta T1 exists until the PTP message is sent out from the interface. That is, there is an error in the transmission timestamp information of the PTP message. Furthermore, since the transmission timestamp information corresponds to a certain PTP message, the transmission timestamp information must be recorded and inserted when a single PTP message can be identified. In the encapsulation stage, it can be identified that a single message belongs to a higher-layer process inside the device, and then undergoes a physical layer process, a queue for transmission, and the like, in the process, the delay Δ T1 may be an unfixed value.
At the receiving end, when the device detects a PTP message, the timestamp of the receiving time is recorded for subsequent PTP protocol processing. When a PTP message reaches a receiving end, a device detects the message and records a timestamp of the receiving time, and a delay delta T2 exists. That is, the PTP reception time stamp information has an error. Moreover, since the receiving timestamp information corresponds to a certain packet, the receiving timestamp information must be recorded when a single packet can be identified, and it can be identified that the single packet belongs to a higher-layer process inside the device, that is, the delay Δ T2 may be relatively large.
It can be seen from the processing in the prior art that the sending end and the receiving end can identify a single message at the time of processing the timestamps, and the timestamps correspond to the sending and receiving moments of a certain PTP message and conform to the PTP protocol. The problem is that the difference delay delta T1 between the sending time stamp information and the sending time of the PTP slave interface and the difference delay delta T2 between the receiving time stamp information and the actual receiving time of the PTP are large, and time errors are introduced to affect the time precision of the equipment. When the time precision requirement of the service is further increased, the precision of the scheme cannot meet the requirement.
For a transmission technology based on a TDM (Time Division Multiplexing) mechanism, a packet needs to be encapsulated into a specific frame format to form a logical channel, and different logical channels may be further combined into a physical channel in order to meet the requirements of 5G slices and the like. The problem of timestamp error in the prior art PTP is even more pronounced because the delay Δ T1 is even greater when the message is encapsulated in a particular frame format and then transmitted. At the receiving end, the Δ T2 is also larger, as the message is parsed and identified from the frame format. It can be seen that the time synchronization of the prior art is less accurate.

Detailed Description
The following detailed description of embodiments of the present invention will be made with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
As shown in fig. 1, an information processing method according to an embodiment of the present invention is applied to a sending end, and includes:
And step 102, taking the sending time stamp information as the sending time stamp of the time synchronization message.
In the embodiment of the present invention, the specific composition and the specific form of the target frame format identifier are not limited, and for example, it may be management information for representing a channel, information for identifying a channel, information for multiplexing a channel, and the like.
In practical application, the sending end device uses the target frame format identifier of the channel where the time synchronization message is located as the identifier for processing the time synchronization timestamp, and processes the timestamp information after identifying the target frame format identifier. Specifically, when the sending end device sends and processes the target frame format identifier, sending timestamp information is generated, and the timestamp information is put into a time synchronization message carried by the channel and used as a sending timestamp of the time synchronization message.
When the channel comprises a plurality of sub-channels, the target frame format identification is the frame format identification of the channel formed by multiplexing the plurality of sub-channels.
Wherein, the message comprises a frame header and a data packet.
In order to provide redundancy protection for the time synchronization message, the sending end processes the target frame format identifier and generates sending timestamp information. The time synchronization message carried by the channel can be a plurality of time synchronization messages, and the plurality of time synchronization messages are put into different time slot positions of the channel. When the channel includes a plurality of sub-channels, the time synchronization packet carried by the channel may be a plurality of time synchronization packets, and the plurality of time synchronization packets are placed in different sub-channels or different time slot positions of the same sub-channel.
For example, there may be one or more time synchronization messages carried in the channel. If a time synchronization packet is carried, the time synchronization packet is carried at any time slot position of the channel as shown in fig. 2(a) and fig. 2 (b). As can be seen from fig. 2(a) and fig. 2(b), the time synchronization packet carried by the channel can be placed in different time slot positions of the channel.
With reference to fig. 2(a) and 2(b), when the target frame format identifier is identified at the 2 nd slot position of the frame format identifier, the transmission time stamp information is generated. And the time synchronization message can be carried on different time slot positions of the channel.
When the channel includes a plurality of sub-channels, as shown in fig. 3(a), fig. 3(b), fig. 3(c), and fig. 3(d), when there is only one time synchronization packet, the time synchronization packet may be carried in different sub-channels; when there are multiple time synchronization messages, the multiple time synchronization messages may be carried at different time slot positions of one of the multiple sub-channels, or carried at any time slot position of different sub-channels.
It can be seen from the above that, in the embodiment of the present invention, the target frame format identifier of the channel where the time synchronization packet is located is used as the identifier for detecting and sending the time synchronization timestamp, rather than determining the sending timestamp or the receiving timestamp when a certain packet is identified as in the prior art, so that it can be ensured that the uncertain time delay of the sub-channel processing and the packet processing is not calculated in the timestamp information when the device performs internal processing, the accuracy of the timestamp information is ensured to the maximum, and the time synchronization precision is improved. In addition, the embodiment of the invention can be applied to the evolution scheme of a higher-precision network.
As shown in fig. 4, the information processing method according to the embodiment of the present invention is applied to a receiving end, and includes:
And the time synchronization message comprises a sending time stamp determined according to sending time stamp information generated by the sending end when the sending end identifies the target frame format identifier.
At the receiving end, when the receiving end device detects the target frame format identifier, the timestamp information of the detected target frame format identifier is recorded as a receiving timestamp, and the receiving timestamp is used as the receiving time information of the time synchronization message carried by the channel.
In order to provide redundancy protection of time synchronization messages, when a plurality of time synchronization messages exist in the same channel, and when a receiving end detects the target frame format identification, recording timestamp information of the detected target frame format identification as a receiving timestamp, and using the receiving timestamp as receiving time information of the plurality of time synchronization messages carried by the channel.
It can be seen from the above that, in the embodiment of the present invention, the target frame format identifier of the channel where the time synchronization packet is located is used as the identifier for detecting and sending the time synchronization timestamp, rather than determining the sending timestamp or the receiving timestamp when a certain packet is identified as in the prior art, so that it can be ensured that the uncertain time delay of the sub-channel processing and the packet processing is not calculated in the timestamp information when the device performs internal processing, the accuracy of the timestamp information is ensured to the maximum, and the time synchronization precision is improved.
In addition, on the basis of the embodiment shown in fig. 4, the receiving end may further obtain the sending timestamp in the time synchronization message, and perform time synchronization processing according to the receiving timestamp and the sending timestamp. Wherein, the process of time synchronization processing according to the receiving time stamp and the sending time stamp is the same as the prior art.
As shown in fig. 5, an information processing apparatus according to an embodiment of the present invention includes: a processor 501 and a transceiver 502;
the processor 501 is configured to generate sending timestamp information when the target frame format identifier of the channel where the time synchronization packet is located is identified; taking the sending timestamp information as a sending timestamp of the time synchronization message;
the transceiver 502 is configured to send a message to a receiving end, where the time synchronization message is carried in the channel, and the time synchronization message includes the sending timestamp.
Optionally, when the channel includes a plurality of sub-channels, the target frame format identifier is a frame format identifier of the channel formed by multiplexing the plurality of sub-channels.
When the time synchronization packet includes a time synchronization packet, the processor 501 is further configured to load the time synchronization packet at any timeslot position of the channel; when the time synchronization packet includes a plurality of time synchronization packets, the processor 501 is further configured to respectively carry the plurality of time synchronization packets at different time slot positions of the channel.
When the time synchronization packet includes a plurality of time synchronization packets, the processor 501 is further configured to load the plurality of time synchronization packets in different time slot positions of one of the plurality of sub-channels; or the processor 501 is further configured to carry multiple time synchronization packets at any timeslot position of different subchannels.
It can be seen from the above that, in the embodiment of the present invention, the target frame format identifier of the channel where the time synchronization packet is located is used as the identifier for detecting and sending the time synchronization timestamp, rather than determining the sending timestamp or the receiving timestamp when a certain packet is identified as in the prior art, so that it can be ensured that the uncertain time delay of the sub-channel processing and the packet processing is not calculated in the timestamp information when the device performs internal processing, the accuracy of the timestamp information is ensured to the maximum, and the time synchronization precision is improved.
As shown in fig. 6, an information processing apparatus according to an embodiment of the present invention includes: a processor 601 and a transceiver 602;
the transceiver 602 is configured to receive a message sent by a sending end, and identify the message;

The processor 601 is further configured to obtain a sending timestamp in the time synchronization message; and carrying out time synchronization processing according to the receiving time stamp and the sending time stamp.
It can be seen from the above that, in the embodiment of the present invention, the target frame format identifier of the channel where the time synchronization packet is located is used as the identifier for detecting and sending the time synchronization timestamp, rather than determining the sending timestamp or the receiving timestamp when a certain packet is identified as in the prior art, so that it can be ensured that the uncertain time delay of the sub-channel processing and the packet processing is not calculated in the timestamp information when the device performs internal processing, the accuracy of the timestamp information is ensured to the maximum, and the time synchronization precision is improved.
