Some embodiments of the invention will now be described in detail with reference to the accompanying drawings. In the case where there is no conflict between the embodiments, the following embodiments and features in the embodiments may be combined with each other. In addition, the sequence of steps in the method embodiments described below is only an example and is not strictly limited.

Fig. 1 is a communication network according to an embodiment of the present invention. As shown in fig. 1, the communication Network may include a Data Network (DN), a core Network, and a radio access Network (Radio Access Network, RAN). Meanwhile, the terminal equipment used by the user can also access the communication network to run various services, and specific content of the services can be seen from the following related description.

Alternatively, the communication network may in particular be a private network deployed in a specific area, such as in an industrial park. The private network may in particular be embodied as a cloud network or as a localization network.

Optionally, the Core Network may be a 5G Core Network (5G Core Network, 5 GC) based on the fifth generation mobile communication technology (5 th Generation Mobile Communication Technology, 5G for short), a 4G Core Network of the fourth generation mobile communication technology (4 th Generation Mobile Communication Technology, 4G for short), or a Core Network of a mixture of 4G and 5G. Wherein, the 5G core network and the 4G core network can have a common core network structure, and are not described in detail herein.

Alternatively, the RAN may comprise an access device. The access device may in particular be embodied as a base station. When the core network is specifically 5GC, the base station may be a 5G base station (the next Generation Node B, abbreviated as gNB).

Alternatively, the DN may include a data server providing a service, which may be a separate server or a cluster of servers. A data server may provide at least one service.

Alternatively, the service provided by the data server to the terminal device may be an instant messaging service, a live broadcast service, an information search service, or the like mentioned in the background art. The voice call service may be a call service provided by various instant messaging applications installed in the terminal device, or a call service provided by a mobile operator. The live video corresponding to the live service can be specifically a live video of a sports event or a game, or can be a live video for realizing remote education and remote medical treatment, and the like. In addition, the services provided by the data server may also include an autopilot service, an Extended Reality (XR) service, and so on. The XR services may specifically further include Virtual Reality (VR) services, augmented Reality (Augmented Reality, AR) services, mixed Reality (MR) services, and so on.

Optionally, the above services provided by the data server may be further classified into a guaranteed rate (Guarantee Bit Rate, GBR) type and a non-guaranteed rate (Non Guarantee Bit Rate, NGBR) type. The information search service may be NGBR type, and the other service may be GBR type.

For the terminal device and the data server, optionally, the terminal device corresponding to the voice call service, the live broadcast service, and the information search service may be a mobile terminal device installed with a corresponding application program, such as a mobile phone, a plane computer, a notebook computer, and so on. The data server for providing the service can store streaming media data such as teaching live video, event live video, medical live video and the like. The terminal device corresponding to the XR service may be a mobile terminal device with application programs such as VR, AR, MR, etc., or may be a wireless, wearable VR device, AR device, MR device, etc. The XR video may be stored in a data server providing this service. The terminal device corresponding to the autopilot service may be a vehicle-mounted terminal device. The data server providing the service can store various vehicle state data collected and reported by the vehicle-mounted terminal equipment, and can also generate control instructions according to the respective vehicle state data so as to control the vehicle to realize automatic driving by utilizing the control instructions.

In the communication network shown in fig. 1, in the process of running the target service, the terminal device and the data server providing the target service can both generate the message to be transmitted. When the message to be transmitted is a downlink message generated by the data server, the downlink message can be transmitted from the data server to the network equipment in the 5GC and then transmitted to the RAN, and the access equipment in the RAN can forward the message to be transmitted to the terminal equipment by utilizing the allocated air interface resources after receiving the message to be transmitted, so that the user can normally use the target service. Alternatively, the target service running on the terminal device may be at least one of the various services mentioned in the embodiment shown in fig. 1. Similarly, when the message to be transmitted is an uplink message generated by the terminal device, the uplink message may also be transmitted to the data server sequentially through the access device and the 5 GC.

The transmission of the message to be transmitted between the terminal equipment and the access equipment can be called air interface side transmission, the transmission between the access equipment and the core network can be called network side transmission, and the transmission between the core network and the data server can be called service side transmission. It should be noted that, the network device for transmitting the uplink and downlink messages in the 5GC may specifically be a device that provides a 5GC user plane function, that is, a user plane element (UPF) network element in the 5GC, and then the transmission of the message on the network side may actually be the transmission of the message between the access device and the UPF network element.

In practice, the transmission delay of the message at either side can reflect the network state, and the state directly affects the service quality of the target service. Therefore, accurately detecting the transmission delay of the message transmitted on different sides, namely sensing the network state of the message transmission, is a precondition for ensuring the service quality.

The schemes provided by the following embodiments of the present invention can be used in order to ensure the quality of service. The following scheme can be used for detecting the transmission delay of the message between the terminal equipment and the access equipment, namely the transmission delay of the air interface side, detecting the transmission delay of the message between the terminal equipment and the core network, and detecting the transmission delay of the message between the terminal equipment and the data server. And finally obtaining the transmission delay of the message at the network side and the service side according to the detected transmission delay. For example, the difference between the transmission delay of the message between the terminal equipment and the core network and the transmission delay of the air interface side is the transmission delay of the network side; the transmission delay of the message between the terminal equipment and the data server is subtracted by the transmission delay of the air interface side, and the transmission delay of the network side is subtracted by the transmission delay of the service side.

Based on the above description, fig. 2 is a schematic structural diagram of another communication network according to an embodiment of the present invention. As shown in fig. 2, the communication network may include a message sending end and a message receiving end, and in an alternative case, a delay determining component may be installed in the message sending end and/or the message receiving end.

Alternatively, the communication network may in particular be a private network, to which the terminal device accesses. The private network may specifically comprise a core network and an access device, and may specifically be a cloud network. Alternatively, the delay determining component may specifically be an extended berkeley packet filter (Extended Berkeley Packet Filter, abbreviated as eBPF) program.

The process of determining the transmission delay of the communication network provided in this embodiment may be described as follows:

the message sending end can firstly obtain the message to be transmitted corresponding to the target service provided by the communication network. Alternatively, the target service may be at least one of the services mentioned in the embodiment shown in fig. 1. The message sending end can normally transmit the acquired message to be transmitted to the message receiving end, namely the message to be transmitted is transmitted in a transparent way. The message receiving end can generate an acknowledgement message (ACK) corresponding to the message to be transmitted after receiving the message to be transmitted, and further feeds back the acknowledgement message to the message receiving end.

The message sending end can analyze the message to be transmitted by utilizing a self-installed time delay determining component based on the acquired message to be transmitted and the acquired confirmation message in an optional time delay determining mode so as to obtain a sending time stamp of the message to be transmitted. After receiving the confirmation message, the message sending end can also continue to analyze the confirmation message by using the time delay determining component, so as to obtain a receiving time stamp of the confirmation message. Finally, the time delay determining component can process the sending time stamp of the message to be transmitted and the receiving time stamp of the confirmation message to obtain the transmission time delay generated when the message to be transmitted is transmitted between the message sending end and the message receiving end. For the processing of the time stamp by the time delay determining component, a common mode is that the time delay determining component makes a difference between the receiving time stamp and the sending time stamp, and the difference is the transmission time delay of the message to be transmitted. The relationship among the pending message, the sending timestamp, the acknowledgement message, and the receiving timestamp can be understood in conjunction with fig. 3 a.

Alternatively, the message to be transmitted and the acknowledgement message may be messages based on a transmission control protocol (Transmission Control Protocol, abbreviated as TCP). The message header of each of the message to be transmitted and the confirmation message may include a field, i.e., a timestamp option (timestamp option). The delay determination component can obtain the transmit timestamp and the receive timestamp by parsing the timestamp option in the header.

Alternatively, the format of a timestamp option in a TCP packet may be as shown in fig. 3 b. As shown in fig. 3b, the timestamp option includes a category (kine), a length (length), a transmit timestamp (TS Value), and a receive timestamp (TS Echo Reply). The total length of the timestamp option shown in fig. 3b is 10 bytes, the two timestamps are 4 bytes each, and the category and length are 1 byte each. It should be noted that the present invention is not limited to the format of the timestamp option, and fig. 3b is only an illustration.

Based on the timestamp options in the format, the sending timestamp contained in the timestamp option of the message to be transmitted is not null and the receiving timestamp is null; the time stamp option of the acknowledgement message contains neither a transmit time stamp nor a receive time stamp that is null. At this time, in another optional delay determining manner, after receiving the acknowledgement message, the message sending end may directly parse the acknowledgement message to obtain a sending timestamp and a receiving timestamp, so as to further determine the transmission delay.

In another optional delay determining mode, after the message receiving end receives the message to be transmitted, the message receiving end can also analyze the sending time stamp of the message to be transmitted from the message receiving end by means of the self-installed delay determining component. And the message sending end can also feed back the receiving time stamp to the message receiving end after analyzing the receiving time stamp from the confirmation message by the time delay determining component. The message receiving end can process the sending time stamp and the receiving time stamp by means of the time delay determining component so as to obtain the transmission time delay of the message to be transmitted. The processing manner of the message receiving end on the timestamp can be referred to the above description.

In this embodiment, a message to be transmitted corresponding to a target service provided by a communication network may be transmitted between a message sending end and a message receiving end in the communication network. In the transmission process, a time delay determining component installed in a message sending end and/or a message receiving end can analyze a sending time stamp of a message from the message to be transmitted; meanwhile, the time delay determining component can also analyze the receiving time stamp of the confirmation message from the confirmation message which is generated by the message receiving end and corresponds to the message to be transmitted. Finally, the time delay determining component can determine the time delay of the transmission of the message to be transmitted between the two ends of the message receiving and transmitting according to the two time stamps.

In the method, the transmission delay affecting the service quality of the target service can be directly detected by means of the delay determining component independently arranged in the message sending end and/or the message receiving end under the condition of not modifying the protocol stack used by the communication network. Namely, the detection of the transmission delay is realized under the condition of not invading the communication protocol, namely, the decoupling of the delay detection and the protocol stack modification is realized. In addition, in the above process, the transmission delay affecting the service quality of the target service is determined by directly using the message to be transmitted corresponding to the target service, and the communication network does not need to generate an additional detection message, so that the transmission pressure of the network can be reduced.

Optionally, the message sending end in the embodiment shown in fig. 2 may be any one of the terminal device, the access device and the UPF network element in the communication network shown in fig. 1, so that the technical effects that can be achieved by the embodiment shown in fig. 2 may be further understood as follows:

according to the embodiment shown in fig. 1, the message to be transmitted corresponding to the target service may be represented as a downlink message generated by the data server providing the target service, and the data server may generate an additional detection message while generating the downlink message, and may use the detection message to detect for time delay detection. Alternatively, the detection message may specifically be a periodically generated measurement message or a ping command.

If the above manner is adopted, on one hand, the types of the messages corresponding to the to-be-transmitted messages of the detection message and the target service are different, and the generation period is also different, for example, the detection message can be generated periodically, the generation time of the to-be-transmitted message is not fixed, and the transmission delay detected by the data server by using the detection message often cannot accurately reflect the transmission delay of the to-be-transmitted message corresponding to the target service, so that the network state cannot be accurately obtained. On the other hand, the additionally generated detection message is used for detecting the time delay, and the message transmission pressure of the whole communication network is increased. In practice, the detection message is usually additionally generated by the data server, so that the generation of the detection message not only can make the processing logic of the data server more complex, but also can occupy the transmission resources of the communication network, thereby finally affecting the stability of the target service.

The method in the embodiment shown in fig. 2 is to directly use the message to be transmitted corresponding to the target service to detect the transmission delay, so that the problems can be improved at the same time, that is, the processing logic of the data server can be simplified while the accuracy of delay detection is ensured. And the embodiment shown in fig. 2 can transfer the time delay detection function of the data server to any one of the terminal equipment, the access equipment and the UPF network element, and the data server is restarted to generate and transmit the message to be transmitted corresponding to the target service, so that the decoupling of the target service provision and the time delay detection is realized, and the processing logic of the data server is simplified. And is also provided with

As described in the embodiment shown in fig. 1, the message to be transmitted may be an uplink message corresponding to the target service generated by the terminal device, or may be a downlink message generated by a data server that provides the target service. The uplink and downlink messages can be transmitted on the air interface side, the core network side and the service side. In the embodiment shown in fig. 2, the device for determining the transmission delay may be a message sending end and/or a message receiving end. The following embodiments are described by taking the transmission delay determined by the message sending end as an example:

The message sending end may be any one of a terminal device, an access device and a UPF network element in the communication network shown in fig. 1, and in particular, in one case, the message sending end may be the terminal device, the message receiving end may be the access device in the RAN, and the message to be transmitted may be an uplink message generated by the terminal device. At this time, according to the embodiment shown in fig. 2, the terminal device may detect the transmission delay of the message to be transmitted corresponding to the target service on the air interface side by using the delay determining component installed in the terminal device.

In another case, the message sending end may be a terminal device, and the message receiving end may be a UPF network element in 5GC, and the message to be transmitted may be an uplink message generated by the terminal device. At this time, the terminal device may detect the transmission delay of the message to be transmitted between the terminal device and the UPF network element by using the delay determining component installed in the terminal device. Based on the air interface transmission time obtained in the former case, the transmission time delay of the message to be transmitted on the network side can be finally obtained.

In another case, the message sending end may be a terminal device, and the message receiving end may be a data server for providing the target service in the communication network, and the message to be transmitted may be an uplink message generated by the terminal device. At this time, the terminal device may detect the transmission delay of the message to be transmitted between the terminal device and the data server by using the delay determining component installed in itself. Based on the transmission delay of the air interface side, the transmission delay of the message to be transmitted on the service side can be finally obtained.

In the above cases, the terminal device may detect the transmission delays of the uplink messages on different sides by using the delay determining component. Optionally, the delay determining component in the terminal device detects the transmission delay of the uplink message, and the access device, the UPF network element and the data server may not be provided with the delay determining component.

In another case, the message sending end may be a UPF network element in 5GC, the message receiving end may be a terminal device, and the message to be transmitted may be a downlink message generated by a data server providing the target service and received by the UPF network element. The UPF network element may utilize an N6 interface between the UPF network element and the data server to screen a message to be transmitted corresponding to the target service from messages corresponding to different services sent by the data server. And then, detecting the transmission delay of the message to be transmitted between the terminal equipment and the UPF network element by using a delay determining component installed by the self, and finally obtaining the transmission delay of the message to be transmitted at the network side.

In another case, the message sending end may be an access device in the RAN, the message receiving end may be a terminal device, and the message to be transmitted may be a downlink message generated by the data server and transmitted to the access device by the UPF network element. The access device may utilize an N3 interface with the UPF network element to screen the message to be transmitted corresponding to the target service from different messages transmitted by the UPF network element. And then, detecting the transmission delay of the air interface side of the message to be transmitted by using a delay determining component installed by the self.

In the two cases, the access device and the UPF network element can detect the transmission delay of the downlink message at different sides by means of the delay determining component installed by the access device and the UPF network element. Optionally, when the UPF network element or the access device detects the transmission delay of the downlink message by using the delay determining component, the terminal device may not install the delay determining component.

In practice, the number of downlink messages generated by the data server is greater than that of uplink messages, so that in more cases, the delay determining component is installed in the access device or the UPF network element, and the access device or the UPF network element determines the network state by detecting the transmission delay of the downlink messages.

In the above cases, the determination of the transmission delay may also be implemented by the message receiving end corresponding to the message receiving end.

In practice, the message transmitting end may acquire a plurality of messages to be transmitted and a plurality of acknowledgement messages at different times. In order to improve accuracy of determining the transmission delay by the message sending end, the delay determining component may determine a matching relationship between the plurality of messages to be transmitted and the plurality of acknowledgement messages, and then determine the transmission delay by using a sending timestamp of the messages to be transmitted and a receiving timestamp of the acknowledgement messages with the matching relationship.

In an optional matching manner, the delay determining component may obtain a sending timestamp from a header of the message to be transmitted, and may also obtain other header information in the message to be transmitted from the header, for example, a sequence number (sequence number) and/or a connection identifier of a communication connection used for transmitting the message to be transmitted. Alternatively, the communication connection may be a TCP connection. Similarly, the delay determining component may obtain the sequence number of the acknowledgement message and/or the connection identifier of the communication connection used for transmitting the acknowledgement message from the header of the acknowledgement message, while obtaining the reception timestamp from the header of the acknowledgement message. The detection device can determine whether the message to be transmitted and the confirmation message are matched according to their respective serial numbers. Alternatively, if the serial numbers of the two messages are the same or the connection identifiers corresponding to the two messages are the same, the two messages can be considered to be matched. Alternatively, two messages may be considered to match if their sequence numbers are the same and the connection identifications are the same.

In this embodiment, a matching relationship between the message to be transmitted and the confirmation message may be determined according to the connection identifier and/or the serial number. The delay determining component can calculate the transmission delay by using the sending time stamp and the receiving time stamp of the message to be transmitted and the confirmation message with the matching relationship so as to improve the accuracy of delay detection. In addition, the details of the embodiment that are not described in detail and the technical effects that can be achieved can be referred to the related descriptions in the above embodiments, which are not described herein.

In addition, for the transmission delay obtained by the message sending end and/or the message receiving end, an optional use mode can determine whether to adjust the configuration parameters of the message sending end and/or the message receiving end according to whether the transmission delay meets the preset requirement. Specifically, if the transmission delay does not meet the preset requirement, which indicates that the network state between the current message sending end and the message receiving end is not good, and the network state does not meet the preset service quality of the target service, the message sending end can automatically adjust the configuration parameters of the message sending end. When the message sending end and the message receiving end are different devices in the communication network, the transmission delay can respectively reflect network states of an air interface side, a network side and a service side.

Optionally, when the message sending end or the message receiving end is the access device, the adjusted configuration parameters may include air interface parameters; when the message sending end is an access device or a UPF network element, the adjusted configuration parameters may include a quality of service (Quality of Service, qoS for short) parameter, and the like.

For example, when the target service is a live broadcast service, that is, the message to be transmitted is represented as a video stream generated by the data server, if the transmission delay of the message to be transmitted does not meet the preset requirement, the access device or the UPF network element serving as the message sending end can obtain more resources by adjusting the configuration parameters of the access device or the UPF network element so as to ensure the normal transmission of the video stream, that is, the smooth transmission of the video is realized while the video resolution is not reduced, that is, the quality of the live broadcast service is ensured. The access device or the UPF network element may also be used as a message receiving end.

Alternatively, the message sending end or the message receiving end may also send the transmission delay to a data server providing the target service in the communication network, where the data server may adjust its configuration parameters according to the transmission delay. The configuration parameters may include, in particular, network configuration parameters and service configuration parameters of the data server. The adjusted network configuration parameters may include a timeout (timeout) parameter, among others. When the target service is a live service, that is, the downlink message is embodied as a video stream, the adjusted service configuration parameter may further include a code rate of the video stream.

For example, when the message to be transmitted is represented as a video stream generated by the data server and the transmission delay does not meet the preset requirement, the data server can automatically adjust its configuration parameters to reduce the code rate of the video stream, so as to ensure smooth transmission of the video by reducing the resolution of the video. Therefore, after the data server adjusts the configuration parameters, the service quality is reduced to some extent, but the normal use of the service by the user is not affected as a whole.

In another optional usage manner, the message sending end and/or the message receiving end may display a transmission delay of the message to be transmitted, so that an operation and maintenance person of the communication network determines whether to adjust configuration parameters of the message sending end or the data server.

In practice, the above-mentioned transmission delay may be used alternatively.

In this embodiment, after the transmission delay is obtained, in a case, the message sending end, the message receiving end or the data server may automatically adjust its configuration parameters according to the transmission delay. When the message sending end and/or the message receiving end adjust the configuration parameters of the message sending end and/or the message receiving end according to the transmission delay, the service quality can be ensured. When the message sending end and the message receiving end do not adjust the configuration parameters, and the data server adjusts the configuration parameters according to the transmission delay, the user is ensured to normally use the target service under the condition of sacrificing a part of service quality. In another case, the message sending end can also display the transmission delay, so that the operation and maintenance personnel can further process the transmission delay, and the adjustment of the configuration parameters is more reasonable.

In the above embodiments, when the to-be-processed message body represents the downlink message generated by the data server, the process of detecting the transmission delay by the delay determining component may specifically include a screening stage of the message, an acquiring stage of the timestamp, and a determining stage of the delay.

At this time, in an alternative implementation manner, the delay determining component may be in a kernel mode of the operating system of the message sending end all the time, after screening the message to be transmitted, the delay determining component may parse the sending timestamp and the receiving timestamp from the respective message header of the message to be transmitted and the acknowledgement message, and then determine the transmission delay of the message to be transmitted according to the parsed timestamps. The transmission delay can also be stored in the kernel space of the message sending end. Alternatively, the transmission delay may be stored in a database provided in the kernel space.

At this time, the message sending end and/or the message receiving end can read the transmission delay from the kernel space to perceive the current network state, and then the receiving and sending ends of the message or the data server can choose to adjust the configuration parameters thereof according to the read transmission delay.

In this embodiment, the time stamp obtaining stage and the determining stage in the delay detection process may be processed in the kernel state by the delay determining component.

In another alternative implementation, the latency determination component may run in different states of the operating system, i.e., kernel mode and user mode. The time delay determining component running in the kernel mode can screen the message to be transmitted, then analyze the sending time stamp and the receiving time stamp from the respective message heads of the message to be transmitted and the confirmation message, and the sending time stamp and the receiving time stamp can be stored in the kernel space of the message sending end. Then, the detection device can switch to user mode operation of the operating system, and determines transmission delay of the message to be transmitted according to the sending timestamp and the receiving timestamp read from the kernel space.

In this embodiment, the packet screening stage and the timestamp obtaining stage in the delay detection process are performed in the kernel mode by the delay determining component, and the calculation stage of the transmission delay is performed in the user mode by the delay determining component. And the computation phase is performed in the user mode to reduce the complexity of the delay determination component.

The delay determining component can also transmit the message to be transmitted corresponding to the target service to the message receiving end in a transparent way while performing delay detection according to any mode. And the time delay determining component can respectively utilize different functional components to realize screening of the message, acquisition of the time stamp, calculation of the time delay and transparent transmission of the message.

For ease of understanding, the process of latency detection for a communication network provided by the above embodiments may be described in the following. In the following embodiments, the transmission delay may be determined by the packet sending end.

In particular, the communication network may be a private network, which may represent a cloud network, which may provide the terminal device with at least one target service in the embodiment shown in fig. 1. Assuming that the target service is a live broadcast service, the message to be transmitted can be a live broadcast video stream sent by the data server, and the message to be transmitted is a downlink message.

In the case, a delay determining component is installed in a UPF network element of the core network, and the UPF network element can receive a downlink message which is initiated by data and contains a live video stream by using an N6 interface.

The parsing component in the delay determining component can parse the downlink message to obtain a sending timestamp of the downlink message. Meanwhile, the transparent transmission component in the time delay determination component can transparent transmit the downlink message to the terminal equipment so that the terminal equipment feeds back a confirmation message of the downlink message to the UPF network element. At this point, the parsing component may continue parsing the acknowledgement message to obtain a receive timestamp. And the processing component in the time delay determining component is used for determining the transmission time delay of the downlink message between the UPF network element and the terminal equipment according to the two analyzed time stamps.

In another case, the base station in the RAN may also be equipped with a delay determining component, and the UPF network element may send a downlink packet to the base station using a 3N interface. The base station may also detect the transmission delay of the downlink message between the base station and the terminal device, i.e. the transmission delay on the air interface side, similar to the UPF network element.

The above procedure can be understood in connection with fig. 4 a.

Assuming that the target service is an automatic driving service, the message to be transmitted can be the vehicle-mounted terminal equipment for collecting the running state data of the vehicle, and the message to be transmitted is an uplink message. And the vehicle-mounted terminal equipment can be provided with a time delay determining component, and at the moment, the time delay determining component in the vehicle-mounted terminal equipment can also perform transmission time delay detection similar to the process, so as to obtain the transmission time delay of the uplink message between the vehicle-mounted terminal equipment and the base station, namely the transmission time delay of the air interface side. Optionally, the base station and the UPF network element may also be provided with delay determining components to detect transmission delays on different sides.

The above procedure can be understood in connection with fig. 4 b.

In each of the above cases, each of the delay determination components may alternatively be run on the UPF network element to provide the same or different states of the operating system.

Optionally, the device provided with the delay determining component can directly and automatically adjust its configuration parameters according to the transmission delay, so as to ensure that the user normally uses the target service. Optionally, the transmission delay detected by the delay determining component may also be displayed on the operation interface, so that the operation and maintenance personnel can select whether to adjust the configuration parameters of the device.

The above embodiments have described the process of detecting the transmission delay of the message transmitting end from the perspective of the whole communication network, and on this basis, the detailed description can also be made from the perspective of the message transmitting end.

Fig. 5 is a schematic structural diagram of a network device according to an embodiment of the present invention. The network device may be deployed in a private network represented as a cloud network, where the network device is an access device or a UPF network element in the foregoing embodiments. As shown in fig. 5, the network device may specifically include a latency determining component and a communication component, where the latency determining component is installed in an operating system of the network device. The communication component is used for transmitting messages according to a network seven-layer protocol (Open System Interconnection, OSI for short). The network device also includes a central processing unit (Central Processing Unit, CPU) that provides a hardware environment for the operating system.

For clarity of the following description, the network device shown in fig. 5 may be referred to as a target network device. The communication component in the target network device may obtain the message to be transmitted corresponding to the target service. The message to be transmitted may be an uplink message generated by the terminal device or a downlink message generated by the data server. The target network device can transmit the message to be transmitted to other network devices in the private network by means of the delay determining component. The other network devices are the message receiving ends in the above embodiments.

After receiving the message to be transmitted, the other network devices can feed back a confirmation message corresponding to the message to be transmitted to the target network device, and the confirmation message can also be acquired by means of the communication component. The delay determining component in the target network device can obtain the sending time stamp of the message to be transmitted and the receiving time stamp of the confirmation message by analyzing the message header, and determine the transmission delay of the message to be transmitted between the target network device and other network devices according to the two time stamps.

In this embodiment, a communication component of a target network device in a private network is configured to obtain a message to be transmitted and receive a confirmation message corresponding to the message to be transmitted. The delay determining component of the target network device is used for analyzing the sending time stamp and the receiving time stamp from the message, and determining the delay of the transmission of the message to be transmitted between the two ends of the message receiving and transmitting according to the two time stamps.

It can be seen that by means of the independently arranged delay determining component, the transmission delay affecting the quality of service of the target service can be directly detected without modifying the protocol stack used by the communication network. Namely, the detection of the transmission delay is realized under the condition of not invading the communication protocol, namely, the decoupling of the delay detection and the protocol stack modification is realized. In addition, in the detection process, the transmission delay affecting the service quality of the target service is detected by directly utilizing the message to be transmitted corresponding to the target service, and the communication network does not need to generate an additional detection message, so that the transmission pressure of the network can be reduced.

In addition, the details of the embodiment that are not described in detail and the technical effects that can be achieved can be referred to the related descriptions in the above embodiments, which are not described herein.

Based on the embodiment shown in fig. 5, as shown in fig. 6, the delay determining component in the network device may specifically include a parsing component, a processing component, and a transparent transmission component.

In an alternative implementation, each component of the latency determination component runs in a kernel mode of an operating system of the network device. The parsing component may screen the message to be transmitted corresponding to the target service from the acquired message, and determine a sending timestamp from the header of the message to be transmitted. The transparent transmission component is used for sending the message to be transmitted to other network devices so that the other network devices can generate the confirmation message corresponding to the message to be transmitted. After the target network device receives the acknowledgement message, the parsing component may continue parsing the reception timestamp from the header of the acknowledgement message. The processing component can process the sending time stamp and the receiving time stamp to obtain the transmission delay of the message to be transmitted. The propagation delay may also be stored in the kernel space of the target network device.

In the above manner, the latency determining component is always running in kernel mode.

Alternatively, the components of the latency determination component operate in different states of the operating system of the network device. Namely, the analysis component and the transparent transmission component operate in a kernel mode, and the processing component operates in a user mode.

Specifically, the parsing component running in the kernel mode may screen a message to be transmitted corresponding to the target service from the acquired message, and determine a sending timestamp from a header of the message to be transmitted. The transparent transmission component running in the kernel mode is used for sending the message to be transmitted to other network devices so that the other network devices can generate the confirmation message corresponding to the message to be transmitted. After the target network device receives the acknowledgement message, the parsing component may continue parsing the reception timestamp from the header of the acknowledgement message. The timestamp parsed by the parsing component may be stored in kernel space of the target network device. The processing component running in the user mode may read the time stamp from the kernel space by means of an interface provided by the time delay determining component, and determine the transmission time delay of the message to be transmitted according to the read time stamp.

In the above manner, the time delay determining component has a switching process between the memory state and the user state in the operation process.

In this embodiment, each component in the delay determining component may operate in the same state or different states of the operating system, so as to implement detection of the transmission delay. In addition, the details of the embodiment that are not described in detail and the technical effects that can be achieved can be referred to the related descriptions in the above embodiments, which are not described herein.

Based on the system and equipment angles, the process of detecting the time delay of the message transmitting end can be described from the flow angle. Fig. 8 is a flowchart of a delay determining method according to an embodiment of the present invention. The time delay determining method provided by the embodiment of the invention can be executed by a message sending end and/or a message receiving end in a communication network. As shown in fig. 8, the method may include the steps of:

s101, obtaining a message to be transmitted corresponding to a target service provided by a communication network, wherein the message to be transmitted is sent to a message receiving end in the communication network by a message sending end.

S102, determining a sending time stamp of a message to be transmitted and a receiving time stamp of a confirmation message corresponding to the message to be transmitted by means of a time delay determining component, wherein the confirmation message is generated after the message to be transmitted is received by a message receiving end.

S103, processing the sending time stamp and the receiving time stamp by means of the time delay determining component to obtain the transmission time delay of the message to be transmitted.

The determining process of the confirmation message and the parsing process of the message may refer to the related description in the embodiment shown in fig. 2, which is not described herein.

In the method, the transmission delay affecting the service quality of the target service can be directly detected by means of the delay determining component independently arranged in the message sending end and/or the message receiving end under the condition of not modifying the protocol stack used by the communication network. Namely, the detection of the transmission delay is realized under the condition of not invading the communication protocol, namely, the decoupling of the delay detection and the protocol stack modification is realized. In addition, in the detection process, the transmission delay affecting the service quality of the target service is detected by directly utilizing the message to be transmitted corresponding to the target service, and the communication network does not need to generate an additional detection message, so that the transmission pressure of the network can be reduced. In addition, the communication network does not need to generate an additional detection message in the detection process, so that the transmission pressure of the network can be reduced.

In practice, the message transmitting end may acquire a plurality of messages to be transmitted and a plurality of acknowledgement messages at different times. In order to further improve accuracy of delay detection, fig. 9 is a flowchart of another delay determination method according to an embodiment of the present invention. As shown in fig. 9, the following steps may be included:

s201, obtaining a message to be transmitted corresponding to a target service provided by a communication network, wherein the message to be transmitted is sent to a message receiving end in the communication network by a message sending end.

S202, determining a sending time stamp of a message to be transmitted and a receiving time stamp of a confirmation message corresponding to the message to be transmitted by means of a time delay determining component, wherein the confirmation message is generated after the message to be transmitted is received by a message receiving end.

The specific implementation process of step S201 to step S202 may refer to the specific description of the related steps in the embodiment shown in fig. 8, which is not repeated here.

Alternatively, the message sending end may be other devices in the communication network besides the data server.

The delay determining component may determine a matching relationship between the plurality of messages to be transmitted and the plurality of acknowledgement messages, and then determine the transmission delay by using a transmission timestamp of the message to be transmitted and a reception timestamp of the acknowledgement message having the matching relationship. Optionally, the delay determining component may determine the matching relationship between the to-be-transmitted message and the acknowledgement message according to other header information in the header, for example, a sequence number (sequence number) and/or a connection identifier of a communication connection used for transmitting the to-be-transmitted message. Specific procedures can be found in the relevant description of the above embodiments,

In this embodiment, the delay determining component may determine a matching relationship between the to-be-transmitted message and the acknowledgement message according to the connection identifier and/or the sequence number. The time delay determining component can calculate the transmission time delay by reusing the sending time stamp and the receiving time stamp of the message to be transmitted and the confirmation message with the matching relation so as to improve the accuracy of time delay detection. In addition, the details of the embodiment that are not described in detail and the technical effects that can be achieved can be referred to the related descriptions in the above embodiments, which are not described herein.

Alternatively, in the above method, the message sending end and the message receiving end may be specifically represented by different devices in the communication network, and specific reference may be made to the description in the above related embodiments.

Optionally, for the transmission delay detected by the delay determining component, in an optional use manner, the message sending end and/or the message receiving end with the delay determining component can automatically determine whether to adjust the configuration parameters thereof according to the transmission delay. Alternatively, the message sending end and/or the message receiving end provided with the time delay determining component can display the transmission time delay, and an operation and maintenance person of the communication network determines whether to adjust the configuration parameters of the message sending end. Yet another alternative may be to send the transmission delay to the data server to automatically determine by the data server whether to adjust its own configuration parameters.

In the above embodiments, when the to-be-processed message body represents the downlink message generated by the data server, the process of detecting the transmission delay by the delay determining component may specifically include a screening stage of the message, an acquiring stage of the timestamp, and a determining stage of the delay. Alternatively, different phases of the delay detection may be implemented by the delay determining component, and the delay determining component may operate in different states in the operating system of the message sender.

In one case, the latency determination component may execute in the kernel mode of the operating system for each stage in the latency detection process.
