Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

Example one

The devices involved in the video conferencing system may include a conference control client, a chairman terminal, a participant terminal, a video networking server, a switch, and a signaling analysis device.

The conference control client is used for establishing the video conference, for example, selecting the participant terminals for group conference, setting the roles of the participant terminals in the conference, and the like. The conference control client may be conference control software, and the conference control client may be installed on a device such as a PC (personal computer), a mobile phone, a wearable device, and the like. The chairman terminal is a terminal selected before the meeting and is used as a control party for sending the conference signaling, and the conference signaling can be sent from the chairman terminal. The participating terminal is a terminal participating in the video conference of the video network and is used for receiving the conference signaling and executing corresponding operation. The chairman terminal and the participant terminal can be video networking terminals, such as a set top box and a PC based on a video networking protocol. The video network server carries the main service of the video network, sends control signaling to the terminal and responds to some request signaling. The master server and the slave server are divided according to the location in the network. The master server is connected with different slave servers, and the slave servers are connected with different terminals. The switch is a device located between the video network server and the terminal, and the terminal is accessed to the video network server through the switch. The signaling analysis device is a device for analyzing the conference signaling, and the signaling association method in the embodiment of the invention can be applied to the signaling analysis device.

In the video conference process of the video network, if certain operation is to be executed, such as switching of speakers, dynamic conference joining and the like, a conference signaling can be sent to the video network server through the chairman terminal, and the video network server forwards the conference signaling to a switch connected with a participating terminal which needs to receive the conference signaling, and then forwards the conference signaling to the corresponding participating terminal through the switch. In the embodiment of the invention, the signaling analysis equipment can be in communication connection with the switch, when the switch receives the conference signaling forwarded by the video networking server, the switch forwards the conference signaling to the signaling analysis equipment, and the signaling analysis equipment analyzes the conference signaling so as to establish the association between the conference signaling and the operation.

Referring to fig. 5, a flowchart illustrating steps of a signaling association method according to a first embodiment of the present invention is shown.

The signaling association method of the embodiment of the invention can comprise the following steps:

step 501, after receiving a current conference signaling in a video conference, obtaining a time interval between the current conference signaling and a previous conference signaling, and judging whether the time interval is greater than a set threshold value.

Conference signaling is a control signal associated with a conference that controls the start, end, speaker switching, etc. of the conference. An operation may contain multiple conference signaling that together perform an operational task. By analyzing the signaling belonging to the same operation, it can be found that the conference signaling generated by each operation is basically in a very short time. Fig. 6 is a scatter plot diagram of signaling generation time and time interval according to a first embodiment of the present invention, in fig. 6, the horizontal axis represents signaling generation time, and the vertical axis represents signaling time interval. As shown in fig. 6, it can be seen that the conference signaling exhibits a high time aggregation, and the time interval between the conference signaling belonging to the same operation is small. Therefore, in the embodiment of the invention, the conference signaling and the operation can be associated through the time interval between the conference signaling.

The signaling analysis equipment initializes first, sets the current operation and time interval, initializes the current operation as null, and initializes the time interval to 0. The current operation may represent the operation of the last received conference signaling association.

After receiving a conference signaling sent by the switch, the signaling analysis device takes the conference signaling as a current conference signaling, records the time of receiving the current conference signaling, and acquires the time interval between the current conference signaling and the previous conference signaling.

If the last conference signaling does not exist, namely the current conference signaling is the first received conference signaling, the time interval is 0, only the time for receiving the current conference signaling is recorded, and the conference signaling continues to be received.

If the last conference signaling exists, namely the current conference signaling is not the first received conference signaling, the recorded time for receiving the last conference signaling is obtained, and the time interval between the current conference signaling and the last conference signaling can be determined according to the time for receiving the last conference signaling and the time for receiving the current conference signaling.

A threshold value is preset, the correlation between the conference signaling with the time interval within the threshold value is strong, and the probability that the conference signaling belongs to the same operation is high. For the specific value of the threshold, a person skilled in the art may set any suitable value according to the duration of the conference signaling in operation, for example, the value may be set to 1s, 1.5s, 2s, and the like, and the embodiment of the present invention is not limited thereto.

And after the time interval between the current conference signaling and the previous conference signaling is acquired, comparing the time interval with a preset threshold value. If the time interval is less than or equal to the set threshold, go to step 502; if the time interval is greater than the set threshold, step 505 is performed.

Step 502, when the time interval is less than or equal to a set threshold, acquiring the recorded current operation, and determining whether the current operation is empty.

If the time interval between the current conference signaling and the previous conference signaling is less than or equal to the set threshold, the current conference signaling and the previous conference signaling belong to the same operation, so that the recorded current operation can be obtained. The current operation of the record may or may not be null. If the current operation is not null, go to step 503; if the current operation is null, step 504 is performed.

Step 503, when the current operation is not empty, establishing the association between the current conference signaling and the current operation.

The current operation is not null, which indicates that the last conference signaling is successfully associated with the operation, i.e. the last conference signaling is associated with the current operation. If the time interval between the current conference signaling and the previous conference signaling is less than or equal to the set threshold and the current operation is not null, it can be determined that the current conference signaling and the previous conference signaling belong to the same operation, so that the association between the current conference signaling and the current operation is established.

Step 504, when the current operation is empty, determining whether the current conference signaling is an operation identification signaling, if the current conference signaling is the operation identification signaling, inquiring the operation associated with the current conference signaling, and recording the inquired operation as the current operation.

The current operation is null, which indicates that the previous conference signaling is not successfully associated with the operation, i.e., there is no operation associated with the previous signaling. And if the time interval between the current conference signaling and the previous conference signaling is less than or equal to the set threshold and the current operation is null, the current conference signaling and the previous conference signaling cannot be associated to the same operation. In this case, the processing may be performed according to the situation of the current conference signaling itself, and it is determined whether the current conference signaling is an operation identification signaling, so as to determine whether a new operation is generated.

In an alternative embodiment, the step of determining whether the current conference signaling is operation identification signaling may include: analyzing the current conference signaling, and extracting field information used for representing a signaling identifier from the current conference signaling; and searching whether the field information exists in the preset signaling identifiers of a plurality of operation identification signaling, and if so, determining that the current conference signaling is the operation identification signaling.

An operation identification signaling is set in advance for each operation, the operation identification signaling can be used as an identification of the operation, and generally, the first conference signaling of the operation can be set as the operation identification signaling. The association relationship between the operation identification signaling and the operation is saved, and the association relationship between the signaling identification of the operation identification signaling and the name of the operation can be saved in the implementation.

The conference signaling may be a structure of a video networking protocol request packet, and in the structure of the conference signaling, a field indicating a signaling identification, a field indicating an operation code, and the like may be included. Analyzing the current conference signaling, extracting field information used for representing a signaling identifier, and then searching whether the field information exists in the stored signaling identifiers of a plurality of operation identification signaling, wherein if the field information exists, the current conference signaling is the operation identification signaling, and if the field information does not exist, the current conference signaling is not the operation identification signaling.

If the current conference signaling is the operation identification signaling, the operation associated with the current conference signaling can be inquired from the stored association relationship between the operation identification signaling and the operation, the inquired operation is recorded as the current operation, and the association between the inquired operation and the current conference signaling is established. And if the current conference signaling is not the operation identification signaling, the current conference signaling is not successfully associated with the operation and is not processed temporarily.

And 505, clearing the recorded current operation when the time interval is larger than a set threshold value.

If the time interval between the current conference signaling and the previous conference signaling is larger than the set threshold, the current conference signaling and the previous conference signaling do not belong to the same operation, and the recorded current operation can be cleared under the condition.

Step 506, determining whether the current conference signaling is an operation identification signaling, if the current conference signaling is the operation identification signaling, inquiring the operation associated with the current conference signaling, and recording the inquired operation as the current operation.

After the recorded current operation is cleared, the current operation can be processed according to the self condition of the current conference signaling, and whether the current conference signaling is the operation identification signaling or not is determined so as to determine whether a new operation is generated or not.

The detailed description of step 506 is substantially the same as step 504 described above, and reference may be made to the above description of step 504, and embodiments of the present invention are not discussed in detail herein.

The following examples are given. Table one shows information associated with a portion of the conference signaling and operation. The signaling identifier of the signaling in table one includes a main identifier and a sub identifier, where 8e01 is listed as the main identifier, 1120 is listed as the sub identifier, and the main identifier and the sub identifier are combined into the signaling identifier.

Watch 1

The data in table one is taken as an example for explanation.

1. When the 1 st signaling 8e01-1120 is received, the signaling is an operation identification signaling corresponding to the operation of switching the first speaker, so that the association operation of switching the first speaker is performed, and the following signaling, the time interval of which is smaller than the set threshold value, is associated with the operation of switching the first speaker;

2. when the 9 th signaling 8f85-4321 is received, the time interval between the signaling and the 8 th signaling is greater than a set threshold, the operation is set to be null, and the signaling 8f85-4321 is not the operation identification signaling of a certain operation, so the operation cannot be related;

3. upon receipt of the 10 th signaling 8e01-1220, although the operation is set to null, the signaling 8e01-1220 is the operation identifying signaling corresponding to the operation "dynamic rendezvous", and thus the signaling is associated with the operation "dynamic rendezvous".

In the embodiment of the invention, based on the rule that the time interval of two adjacent conference signals in a plurality of conference signals generated by each operation is smaller, the conference signals can be associated with the operation according to the time interval, and the current operation can be updated in time when a new operation is generated, and each conference signal is accurately associated with the operation, so that the conference signals are described more accurately and more specifically.

Example two

Referring to fig. 7, a flowchart illustrating a signaling association method according to a second embodiment of the present invention is shown.

step 701, after receiving a current conference signaling in a video conference, determining whether the current conference signaling belongs to an operational conference signaling.

In the embodiment of the present invention, it is further considered that some conference signaling does not belong to signaling in operation. For example, heartbeat signaling is transmitted during a video conference, but the heartbeat signaling does not belong to a specific operation. Therefore, in order to simplify the processing procedure and avoid performing unnecessary analysis procedures on the signaling which does not belong to the operation, the signaling can be filtered out first. In the implementation, after receiving a current conference signaling in a video conference, determining whether the current conference signaling belongs to an operational conference signaling. If the current conference signaling belongs to the operated conference signaling, executing step 702; and if the current conference signaling is not the conference signaling which does not belong to the operation, skipping the current conference signaling, re-executing the step 701, and continuously receiving the next conference signaling for processing.

In an optional implementation manner, a signaling white list may be preset, where the signaling white list includes a plurality of signaling identifiers belonging to the operated conference signaling. Thus, the step of determining whether the current conference signaling is conference signaling belonging to an operation may comprise: analyzing the current conference signaling, and extracting field information used for representing a signaling identifier from the current conference signaling; searching whether the field information exists in a plurality of signaling identifiers belonging to the operated conference signaling in a preset signaling white list; if the current conference signaling exists, determining that the current conference signaling belongs to the operated conference signaling; and if not, determining that the current conference signaling is conference signaling which does not belong to the operation.

In an alternative embodiment, a signaling blacklist may be preset, where the signaling blacklist includes a plurality of signaling identifiers of conference signaling that does not belong to an operation. Thus, the step of determining whether the current conference signaling is conference signaling belonging to an operation may comprise: analyzing the current conference signaling, and extracting field information used for representing a signaling identifier from the current conference signaling; searching whether the field information exists in a plurality of signaling identifiers of conference signaling which does not belong to the operation in a preset signaling blacklist; if the current conference signaling does not exist, determining that the current conference signaling belongs to the operated conference signaling; and if so, determining that the current conference signaling is conference signaling which does not belong to the operation.

Step 702, obtaining a time interval between the current conference signaling and the previous conference signaling, and determining whether the time interval is greater than a set threshold. If yes, go to step 707; if not, go to step 703.

And 703, when the time interval is less than or equal to a set threshold, acquiring the recorded current operation, and judging whether the current operation is empty. If yes, go to step 705; if not, go to step 704.

Step 704, when the current operation is not empty, establishing the association between the current conference signaling and the current operation. And then returning to the step 701 to continue receiving the next conference signaling for processing.

Step 705, when the current operation is empty, determining whether the current conference signaling is an operation identification signaling. If yes, go to step 706; if not, returning to the step 701, and continuing to receive the next conference signaling for processing.

Step 706, if the signaling is an operation identification signaling, inquiring the operation associated with the current conference signaling, and recording the inquired operation as the current operation. And then returning to the step 701 to continue receiving the next conference signaling for processing.

And step 707, when the time interval is larger than the set threshold value, clearing the recorded current operation.

Step 708, determining whether the current conference signaling is operation identification signaling. If yes, go to step 709; if not, returning to the step 701, and continuing to receive the next conference signaling for processing.

Step 709, if the signaling is an operation identification signaling, inquiring the operation associated with the current conference signaling, and recording the inquired operation as the current operation. And then returning to the step 701 to continue receiving the next conference signaling for processing.

Step 702 to step 709 are substantially the same as step 501 to step 506, and specific reference may be made to the above description of step 501 to step 506, and embodiments of the present invention are not discussed in detail here.

Step 710, when the time interval is greater than a set threshold, comparing the received conference signaling associated with the current operation with all preset conference signaling associated with the current operation, and determining whether the conference signaling associated with the current operation is lost. If yes, go to step 711; if not, returning to the step 701, and continuing to receive the next conference signaling for processing.

In the embodiment of the invention, whether the operation has errors or not is further analyzed. An operation associated with the conference signaling is standard and is incomplete if the conference signaling is lost during reception of the conference signaling.

Therefore, when the time interval between the current conference signaling and the previous conference signaling is judged to be greater than the set threshold, it can be said that the conference signaling associated with the current operation has been sent. In this case, the received conference signaling associated with the current operation and all the preset conference signaling associated with the current operation are obtained, and the received conference signaling associated with the current operation and all the preset conference signaling associated with the current operation are compared to determine whether the conference signaling associated with the current operation is lost.

And 711, if the current operation is lost, displaying alarm information of the lost conference signaling associated with the current operation.

If the conference signaling associated with the current operation is lost, alarm information can be displayed, wherein the alarm information is used for prompting that the conference signaling associated with the current operation is lost and prompting information such as a signaling identifier of a specific lost conference signaling.

It should be noted that, the above-mentioned process of returning to step 701 and continuing to receive the next conference signaling for processing is not shown in fig. 7, and the process does not return to step 701 until all conference signaling is received.

In the embodiment of the invention, the conference signaling can be associated to the operation, and the associated information is promoted from the dimension of the lower layer of the signaling level to the operation dimension, so that the operation and maintenance personnel can understand and accept the information more conveniently.

It should be noted that, for simplicity of description, the method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the illustrated order of acts, as some steps may occur in other orders or concurrently in accordance with the embodiments of the present invention. Further, those skilled in the art will appreciate that the embodiments described in the specification are presently preferred and that no particular act is required to implement the invention.

2. Video networking packet definition

2.1 Access network packet definition

As shown in the following table, the data packet of the access network mainly includes the following parts:

DA

SA

Reserved

Payload

CRC

wherein:

the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of the data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are 256 possibilities at most, the second byte to the sixth byte are metropolitan area network addresses, and the seventh byte and the eighth byte are access network addresses;

the Source Address (SA) is also composed of 8 bytes (byte), defined as the same as the Destination Address (DA);

the reserved byte consists of 2 bytes;

the payload part has different lengths according to different types of datagrams, and is 64 bytes if the datagram is various types of protocol packets, and is 32+1024 or 1056 bytes if the datagram is a unicast packet, of course, the length is not limited to the above 2 types;

the CRC consists of 4 bytes and is calculated in accordance with the standard ethernet CRC algorithm.

2.2 metropolitan area network packet definition

The topology of a metropolitan area network is a graph and there may be 2, or even more than 2, connections between two devices, i.e., there may be more than 2 connections between a node switch and a node server, a node switch and a node switch, and a node switch and a node server. However, the metro network address of the metro network device is unique, and in order to accurately describe the connection relationship between the metro network devices, parameters are introduced in the embodiment of the present invention: a label to uniquely describe a metropolitan area network device.

In this specification, the definition of the Label is similar to that of the Label of MPLS (Multi-Protocol Label Switch), and assuming that there are two connections between the device a and the device B, there are 2 labels for the packet from the device a to the device B, and 2 labels for the packet from the device B to the device a. The label is classified into an incoming label and an outgoing label, and assuming that the label (incoming label) of the packet entering the device a is 0x0000, the label (outgoing label) of the packet leaving the device a may become 0x 0001. The network access process of the metro network is a network access process under centralized control, that is, address allocation and label allocation of the metro network are both dominated by the metro server, and the node switch and the node server are both passively executed, which is different from label allocation of MPLS, and label allocation of MPLS is a result of mutual negotiation between the switch and the server.

As shown in the following table, the data packet of the metro network mainly includes the following parts:

DA

SA

Reserved

label (R)

Payload

CRC

Namely Destination Address (DA), Source Address (SA), Reserved byte (Reserved), tag, payload (pdu), CRC. The format of the tag may be defined by reference to the following: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, and its position is between the reserved bytes and payload of the packet.
