The domestic and foreign 5G research organizations such as ITU, IMT-2020 Pushing group and the like all put forward end-to-end time delay requirements of millisecond level for 5G, and the definition of the end-to-end time delay is as follows: the length of time that the data packet has been received successfully by the application layer of the destination node since the data packet has arrived since the application layer of the source node left. The end-to-end delay comprises air interface delay, core network delay and PDN network delay. In the prior art, the time delay of various communication systems is specifically: ideally the end-to-end delay is 1ms, and typically the end-to-end delay is around 5-10 ms. In the 4G network currently used by us, the end-to-end ideal delay is about 10ms, and the end-to-end delay of LTE is 50-100ms, which means that 5G needs to shorten the end-to-end delay to one tenth of 4G.

Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
The first embodiment is as follows:
referring to fig. 1, fig. 1 is a flowchart of a method for measuring a time delay of end-to-end communication provided in this embodiment, where the method may be specifically implemented based on an existing network management system, and specifically, the method implements analysis of the time delay by monitoring data interaction between an originating terminal and a destination terminal in the system, and the processing steps specifically include:
s101, service communication signaling data sent by a sending end in an end-to-end communication system is monitored, and sending time and a corresponding service type are recorded.
S102, identifying whether the receiving end of the end-to-end communication system receives the service communication signaling data, if yes, recording the corresponding receiving time.
And S103, calculating communication time delay according to the receiving time and the sending time.
In this embodiment, a sending end in the end-to-end communication system refers to a network element that sends a data packet, and a receiving end refers to a network element that receives the data packet and is applied or analyzed, where the whole end-to-end communication system may include two network elements or multiple network elements, and when the whole end-to-end communication system includes multiple network elements, the sending end refers to a first network element in the system, the receiving end refers to a last network element in the system, and the other network elements are used as connection network elements for implementing the first and second network elements.
In this embodiment, the service communication signaling data refers to service transmission data when an end-to-end communication system implements service interaction, where the service transmission data requests sending, feedback receiving, and the like of data through various communication signaling, and therefore the service communication signaling data is a signaling necessary for service output transmission. Certainly, in practical applications, the service communication signaling data may also be a specific communication signaling set specifically for the user when the user analyzes the delay between the end-to-end systems.
In step S102, identifying whether the service communication signaling data sent by the sending end is received from the receiving end specifically by using the established service model, and when the data matched with the service model that has been received at the receiving end is identified, obtaining the receiving time when the data is received.
In practical application, the service model is specifically established according to the existing 3GPP communication protocol, and then, whether the same service data exists on the receiving end is specifically identified, that is, a service model corresponding to the service type is selected from a plurality of service models according to the service type recorded in step S101, whether a service flow matched with the service model exists in the receiving end is identified according to the service model, and corresponding communication signaling data is extracted from the service flow according to the identification result, and corresponding receiving time is recorded.
In this embodiment, the service model specifically includes a signaling model, where the signaling model includes a start signaling group, an intermediate signaling group, and an end signaling group required for triggering the service process, and in practical applications, different services interact with each other and the signaling groups used by the different services are different, so that the identifying whether the receiving end of the end-to-end communication system receives the service communication signaling data may be specifically implemented by the signaling model.
Preferably, a signaling group required for implementing the service interaction is obtained according to a signaling model, and an initial signaling corresponding to the initial signaling group is determined from the communication signaling data according to the signaling group;
searching an ending signaling group corresponding to the starting signaling according to the starting signaling;
and screening the communication signaling data according to the ending signaling group, determining ending signaling in the communication signaling data, and recording the receiving time of the ending signaling confirmed to be received by the receiving end.
In practical application, when performing delay analysis on service communication signaling data in an end-to-end communication system, first determining a corresponding service type and a corresponding signaling model, extracting the corresponding signaling data according to the signaling model, and finally performing delay analysis on the extracted signaling data, where the signaling model is specifically shown in fig. 2, the left half of the diagram shows a signaling flow diagram abstracted according to an actual service flow, and the signaling flow diagram includes three important components:
starting signaling: the trigger signaling of the signaling procedure may also be referred to as the first signaling of the procedure.
And (4) ending signaling: the last signaling of the signaling flow, which identifies the end of the flow. End signaling 1, end signaling 2, … …, end signaling n, as shown at the bottom of the figure, indicate that there are many possibilities for end signaling. This is because the flow may end normally, may end abnormally (for example, the flow fails), or in some other cases, the end signaling is often not unique.
Intermediate signaling: signaling that is transferred and translated between network elements, in addition to the start and end signaling. The part of signaling is characterized in that certain signaling can be conditioned according to different networking, service and other conditions. In view of this feature, the partial signaling can be divided into two broad categories: the signaling that the flow must contain and the signaling that the flow may contain.
According to the above signaling flow, the signaling flow model on the right side of fig. 2 can be mapped. The model has a set of start signaling, intermediate signaling (if any), and end signaling. The start signaling identifies the start of the flow; the intermediate signaling (if any) includes the signaling that must be included in the flow; the intermediate signaling (if any) includes signaling that the condition in the flow occurs; and an end signaling group, which defines several pieces of end signaling corresponding to the flow start signaling (each piece of end signaling may be the end of the flow).
Since the signaling model is the key for extracting signaling data, in order to better understand, the analysis method provided by the embodiment of the present invention defines a signaling model in the following manner, as shown in fig. 3:
starting signaling:
Attach Request
end signaling group:
attach reject (none in FIG. 3, FIG. 3 is a normal flow)
Modify Bearer Response
Intermediate signaling (mandatory):
Create Session Request
Create Session Response
Initial Context Setup Request
…………
intermediate signaling (optional)
Delete Session Request

According to the signaling model and in combination with specific services, a plurality of service flows can be defined, and the extraction and analysis of signaling data are performed according to the signaling model, as shown in fig. 4:
s401, traversing the collected signaling data set.
Specifically, the signaling group in the obtained signaling data set is divided according to the starting signaling combination and the intermediate signaling combination ending signaling group in the signaling model, at least three types of signaling exist in one service flow, and in order to facilitate subsequent query operation, the signaling group needs to be divided according to the signaling model.
S402, judging whether one signaling in the extracted set can be matched with an initial signaling of a certain configured service signaling process, if not, continuously traversing the acquired signaling data set.
S403, if the signaling is the initial signaling of a certain service process, finding an end signaling group corresponding to the initial signaling.
S404, traversing the ending signaling group, extracting an ending signaling from a plurality of ending signaling, then indexing the ending signaling from the next starting signaling of the current signaling in the signaling set, and if no indexing is performed to the ending signaling, continuing traversing the ending signaling until the traversing is ended.
S405, if the ending signaling is indexed, all the signaling in the closed interval is extracted according to the starting signaling number and the ending signaling number.
S406, cleaning the process. And removing the service flow which is not matched with the service model from the service communication signaling data according to the service model.
In practical application, before a flow is extracted, the signaling reported by multiple network elements is sequenced, the sequencing is mainly based on the reporting sequence of single network element signaling and the timestamp of the signaling, and due to the inconsistency of network element time and the complexity of a service (such as data service is being performed and a call comes in between), the extracted flow may be mixed with signaling which is not the flow. The flows can be flushed with the signaling defined in the previous traffic flow (start, end signaling and intermediate signaling), i.e. the signaling not in the flow is removed.
S407, extracting the cleaned signaling, marking the initial signaling and the ending signaling (marking which is the initial signaling and which is the ending signaling), and constructing a signaling flow.
And S408, continuously traversing the collected signaling data set (not starting from the end signaling, but starting from the next piece of the initial signaling) until the last signaling is traversed, and extracting all signaling flows.
In practical application, the ending signaling group includes all possible situations for ending a service, so before calculating the time delay, the signaling in the signaling data is traversed by the method to judge the actual situation of each signaling, if the signaling for calculating the time delay is selected to belong to the ending signaling for abnormally ending the service, the calculated time delay has a very large error, the reference value of the error is very low, the optimization scheme determined by a network maintainer is finally misled, and if the time delay is abnormal, the new signaling data needs to be monitored again to be obtained for analyzing the time delay.
In this embodiment, the obtained signaling model may be a signaling model including all service interactions belonging to an end-to-end communication system, and in this case, if an analysis information amount of heartache occurs during analysis according to such signaling model delay, in order to better avoid such a situation, the method provided by the present invention further includes slicing the obtained service communication signaling data, preferably, slicing according to a service type, where each time slice corresponds to one service, that is, can be understood as a sub-process in a service flow, and then performing model configuration according to the type of the sub-process, where a method for extracting and analyzing a signaling data flow is consistent with the service flow in fig. 4, as shown in fig. 5, this embodiment provides an example of service slice calculation.
In this embodiment, after the sending and receiving time of the corresponding data and signaling is extracted, the corresponding time delay is calculated according to the obtained time, and the analysis result is displayed to the network maintenance staff for performing the optimization processing on the system time delay, as shown in fig. 6:
s601, the ending signaling time of the service process subtracts the starting signaling time to form the delay data of the whole service process.
And S602, subtracting the starting signaling time from the ending signaling time corresponding to the slicing service to obtain corresponding slicing time delay data.
S603, traversing the time delay of the same service flow and the slice in the signaling file, and calculating the average value.
S604, the statistical time delay analysis result is visually displayed to the user, and the effect is shown in figure 7.
And S605, giving a delay analysis report, and taking an example in FIG. 8.
And S606, exporting the delay analysis result support into a file, wherein the format can be html, xls and the like.
In this embodiment, in addition to directly analyzing the interactive signaling data of the service through the above steps to implement the delay analysis, the analysis may also be performed by setting an identifier, specifically by setting a signaling identifier in the service communication signaling data sent by the sending end; monitoring whether the signaling identifier exists in service communication signaling data in the receiving end; and if so, acquiring the receiving time when the service communication signaling data provided with the signaling identifier is received.
The time delay measuring method of end-to-end communication provided by the embodiment of the invention has the advantages that the service communication signaling data sent from the sending end is monitored, the corresponding sending time is recorded, when the receiving end is identified to receive the service communication signaling data, the corresponding receiving time is recorded, and then the communication time delay is calculated according to the receiving time and the sending time, so that the analysis of the communication time delay of the end-to-end communication system is conveniently realized; through the tracking analysis of the service communication signaling data, a powerful basis for network maintenance is provided for communication personnel, and the maintenance efficiency is improved.
Example two:
referring to fig. 9, fig. 9 is a block diagram of a structure of a latency measurement apparatus for peer-to-peer communication according to this embodiment, where the apparatus includes: a data monitoring module 91, an identification module 92 and a time delay calculation module 93, wherein:
the data monitoring module 91 is configured to monitor service communication signaling data sent by a sending end of the end-to-end communication system, and record sending time for sending the service communication signaling data and a service type corresponding to the service communication signaling data.
In this embodiment, the service communication signaling data refers to service transmission data when an end-to-end communication system implements service interaction, where the service transmission data requests sending, feedback receiving, and the like of data through various communication signaling, and therefore the service communication signaling data is a signaling necessary for service output transmission. Of course, in practical application, the service communication signaling data may also be a specific communication signaling specially set for the user when analyzing the time delay between the end-to-end systems.
Wherein, a sending end in the end-to-end communication system refers to a network element that sends a data packet, and a receiving end refers to a network element that receives the data packet and is applied or analyzed, the whole end-to-end communication system may include two network elements or may include multiple network elements, when the multiple network elements are included, the sending end refers to a first network element in the system, the receiving end refers to a last network element in the system, and the others are connection network elements that implement the first and second network elements, as shown in fig. 2.
An identifying module 92, configured to identify whether a receiving end of the end-to-end communication system receives the service communication signaling data, and if so, record receiving time when the receiving end receives the service communication signaling data.
And a delay calculating module 93, configured to calculate a signaling delay of the end-to-end communication system according to the recorded sending time and receiving time.
In this embodiment, the apparatus further includes a model building module 94, where the model building module 94 is configured to build a service model of the end-to-end communication system according to a 3GPP communication protocol.
The identification module 92 is configured to determine a corresponding service model according to the service type; and identifying whether a service flow matched with the service model exists from the receiving end according to the service model, extracting corresponding communication signaling data from the service flow according to an identification result, and recording corresponding receiving time.
Preferably, the service model includes a signaling model, and the signaling model includes a start signaling group, an intermediate signaling group, and an end signaling group required for triggering the service flow, where the start signaling group and the end signaling group trigger and end signaling necessary in the service flow, and the intermediate signaling group determines whether the signaling is required according to an actual situation. For the situation that the ending signaling group includes all possible situations of ending a service, therefore, before calculating the time delay, the signaling in the signaling data is traversed by the method, the actual situation of each signaling is judged, if the signaling for calculating the time delay belongs to the ending signaling for ending the abnormal ending of the service, the calculated time delay has a very large error, the reference value is very low, the optimization scheme determined by the network maintenance personnel is finally misled, and if the abnormal situation occurs, the new signaling data needs to be monitored again to analyze the time delay.
The identifying module 92 is configured to determine, from the communication signaling data, a start signaling corresponding to the start signaling group; searching an ending signaling group corresponding to the starting signaling according to the starting signaling; and screening the communication signaling data according to the ending signaling group, determining ending signaling in the communication signaling data, and recording the receiving time of the ending signaling confirmed to be received by the receiving end.
In practical application, different service interactions and signaling groups used by the different service interactions are different, so that whether the receiving end of the end-to-end communication system receives the service communication signaling data or not can be realized through a signaling model.
For example, when there is a service interaction through the signaling model defined in fig. 3, the obtained service communication signaling data is extracted according to the signaling model in fig. 3, the service communication signaling data is first screened according to the initial signaling group in the signaling model to screen out the initial signaling, and it is determined whether the initial signaling is in the initial signaling group in the model, if not, a rejection step is performed to reject the signaling from the data set; if the signaling exists, recording the initial signaling, recording the corresponding sending time, and continuously judging the next signaling; after all initial signaling in the signaling data is determined, searching a corresponding ending signaling group according to the initial signaling, simultaneously screening whether the ending signaling in the signaling data belongs to the ending signaling group, if so, recording the ending signaling and corresponding receiving time, and finally calculating corresponding communication time delay according to the recorded sending time of the initial signaling and the recorded receiving time of the ending signaling.
In this embodiment, in addition to directly analyzing the interactive signaling data of the service through the above steps to implement the delay analysis, the analysis may also be performed by setting an identifier, specifically by setting a signaling identifier in the service communication signaling data sent by the sending end; monitoring whether the signaling identifier exists in service communication signaling data in the receiving end; and if so, acquiring the receiving time when the service communication signaling data provided with the signaling identifier is received.
In this embodiment, the delay measurement device for end-to-end communication may be specifically configured as a subsystem in a network management system in the end-to-end communication system, and by adding the system, not only is the correctness of the service interaction signaling between the terminals monitored, but also the time required for implementing service flow interaction while the services are interacted at the terminals is analyzed, and a worker may optimally adjust the communication time between the terminals according to the analyzed delay report at any time.
The time delay measuring device for end-to-end communication provided by the embodiment of the invention monitors the service communication signaling data sent by the sending end, records the corresponding sending time at the same time, records the corresponding receiving time when the receiving end is identified to receive the service communication signaling data, and then calculates the communication time delay according to the receiving time and the sending time; the time delay analysis is carried out through the service signaling data interacted with the system, so that the time delay analysis of the system is realized, the time consumed for analyzing the time delay process is shortened, the current situation of the time delay of a communication network and the communication quality of the system are improved for a user, the problem that the positioning analysis calculation of the communication time delay cannot be realized in the communication process of an end-to-end system is solved, the time delay of the system is larger, and the use experience of the user is improved.
Example three:
referring to fig. 10, fig. 10 is a block diagram of a structure of a latency measurement apparatus for peer-to-peer communication according to this embodiment, where the apparatus includes: a processor 11, a memory 12 and a communication bus 13, wherein the memory 12 stores a time delay analysis program, and the time delay analysis program comprises:
the communication bus 13 is used for realizing communication connection between the processor 11 and the memory 12;
the processor 11 is configured to execute the latency analysis program stored in the memory 12 to implement the following steps:
monitoring service communication signaling data sent by a sending end of an end-to-end communication system, and recording the sending time for sending the service communication signaling data and the service type corresponding to the service communication signaling data;
identifying whether a receiving end of an end-to-end communication system receives the service communication signaling data, and if so, recording the receiving time of the receiving end receiving the service communication signaling data;
and calculating the signaling time delay of the end-to-end communication system communication according to the recorded sending time and receiving time.
In practical application, the service communication signaling data refers to service transmission data when an end-to-end communication system realizes service interaction, and the service transmission data requests sending, feedback receiving and the like of data through various communication signaling, so the service communication signaling data is necessary signaling for service output transmission. Of course, in practical application, the service communication signaling data may also be a specific communication signaling specially set for the user when analyzing the time delay between the end-to-end systems.
In this embodiment, the processor 11 is further configured to execute the latency analysis program to implement the following steps:
establishing a service model of the end-to-end communication system according to a 3GPP communication protocol;
determining a corresponding service model according to the service type;
and identifying whether a service flow matched with the service model exists in the receiving end according to the service model, extracting corresponding communication signaling data from the service flow according to an identification result, and recording corresponding receiving time.
Preferably, the service model includes a signaling model, the signaling model includes a start signaling group, an intermediate signaling group, and an end signaling group required for triggering the service process, and when the processor 11 executes the delay analysis program to recognize whether the receiving end of the end-to-end communication system receives the service communication signaling data, the following method is specifically used:
determining, from the communication signaling data, an initial signaling corresponding to the initial signaling group;
searching an ending signaling group corresponding to the starting signaling according to the starting signaling;
and screening the communication signaling data according to the ending signaling group, determining ending signaling in the communication signaling data, and recording the receiving time of the ending signaling confirmed to be received by the receiving end.
In practical application, different service interactions and signaling groups used by the different service interactions are different, so that whether the receiving end of the end-to-end communication system receives the service communication signaling data or not can be realized through a signaling model. For example, when there is a service interaction through the signaling model defined in fig. 3, the obtained service communication signaling data is extracted according to the signaling model in fig. 3, the service communication signaling data is first screened according to the initial signaling group in the signaling model to screen out the initial signaling, and it is determined whether the initial signaling is in the initial signaling group in the model, if not, a rejection step is performed to reject the signaling from the data set; if the signaling exists, recording the initial signaling, recording the corresponding sending time, and continuously judging the next signaling; after all initial signaling in the signaling data is determined, searching a corresponding ending signaling group according to the initial signaling, simultaneously screening whether the ending signaling in the signaling data belongs to the ending signaling group, if so, recording the ending signaling and corresponding receiving time, and finally calculating corresponding communication time delay according to the recorded sending time of the initial signaling and the recorded receiving time of the ending signaling.
In this embodiment, the delay measurement apparatus for end-to-end communication may implement delay analysis by directly analyzing the interactive signaling data of the service, and may also perform analysis by the processor 11 executing the delay analysis program to set an identifier for the service communication signaling data, specifically, by setting a signaling identifier in the service communication signaling data sent by the sending end; monitoring whether the signaling identifier exists in service communication signaling data in the receiving end; and if so, acquiring the receiving time when the service communication signaling data provided with the signaling identifier is received.
Correspondingly, the present invention further provides a computer-readable storage medium, where a time delay analysis program is stored on the computer-readable storage medium, and when the time delay analysis program is executed, the steps of the time delay measurement method for end-to-end communication provided in the foregoing embodiment are implemented.
