[0002] In a dedicated video conferencing system, when a dedicated terminal applies for chairman authority to listen, broadcast, or select other conference terminals, it cannot know the communication quality of other conference terminals because it has not established a connection with other conference terminals.

[0052] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0053] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0054] The embodiment of the present application is applied to any conference terminal in a conference system, and the conference terminal information acquisition method includes: sending a terminal quality information request signaling to a conference control terminal, wherein the conference control terminal is used to send a terminal quality information indication signaling to the conference terminal based on the terminal quality information request signaling after receiving the terminal quality information request signaling sent by the conference terminal; receiving and parsing the terminal quality information indication signaling sent by the conference control terminal, obtaining terminal quality information of at least one conference terminal, and updating the terminal quality information to a terminal list;

[0055] A conference control terminal used in a conference system receives a terminal quality information request signaling sent by any conference terminal in the conference system; based on the terminal quality information request signaling, a terminal quality information indication signaling is sent to the conference terminal, wherein the terminal quality information indication signaling includes terminal quality information of at least one conference terminal, and the conference terminal is used to receive and parse the terminal quality information indication signaling sent by the conference control terminal, and update the parsed terminal quality information to the terminal list.

[0056] In this embodiment, for the convenience of description, the following description is made by taking the conference terminal information acquisition system as the execution subject.

[0057] In the prior art, when a terminal applies for chairperson authority to control other conference terminals, it may select a venue with poor communication quality, which may cause abnormal noise, video image distortion, freezes, and blurs, which not only seriously interferes with the smooth progress of the meeting, but also greatly reduces the video conference user experience.

[0058] The present application provides a solution, which enables the conference terminal to actively obtain, parse and update the terminal quality information of the conference control terminal, so that the optimal conference terminal can be selected for conference operations based on this information, thereby ensuring the communication quality during the meeting, improving the conference experience of video conference users, and effectively solving the problem of unguaranteed communication quality of conference control in existing dedicated video conferencing systems.

[0059] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a conference terminal information acquisition system, etc. The following takes the conference terminal information acquisition system as an example to illustrate this embodiment and the following embodiments.

[0060] Based on this, the present application embodiment provides a method for obtaining conference terminal information, referring to Figure 1 , Figure 1 This is a flowchart of the first embodiment of the conference terminal information acquisition method of the present application.

[0061] In this embodiment, the conference terminal information acquisition method is applied to any conference terminal in the conference system, and includes steps S01 to S02:

[0062] Step S01, sending a terminal quality information request signaling to a conference control terminal, wherein the conference control terminal is used to send a terminal quality information indication signaling to the conference terminal based on the terminal quality information request signaling after receiving the terminal quality information request signaling sent by the conference terminal;

[0063] It should be noted that the conference terminal sends a terminal quality information request signaling to the conference control end. The conference terminal refers to the terminal device participating in the conference, such as the terminal in the video conferencing system. The conference control end refers to the multipoint control unit (MCU) or similar conference terminal information acquisition device, which is responsible for processing conference control signaling and terminal quality information. The terminal quality information request signaling refers to the signaling sent by the conference terminal to the conference control end to request the quality information of other conference terminals, which contains the MT number parameter, which is used to uniquely identify the conference terminal.

[0064] For example, to help understand the technical concept or technical principle of this application, please refer to Figure 2 , Figure 2A schematic diagram of multi-point video communication networking in a dedicated video conferencing system is provided. In the dedicated video conferencing system, the dedicated MCU (multi-point control unit) and dedicated terminals are connected through one or more pairs of E1 dedicated lines. The E1 dedicated line is a network communication line with high-speed data transmission, which is mainly used for enterprise-level network connection. Multi-point video communication is achieved between dedicated terminals through the MCU. The dedicated video conferencing realizes the conference control function through the control and indication signaling specified by the H.230 protocol.

[0065] It is understandable that the existing solutions often lack a mechanism to actively obtain terminal quality information, such as Figure 2 As shown, since no connection is established between conference terminals, when a terminal needs to select other terminals for listening, broadcasting or viewing, a conference terminal with poor communication quality may be selected, so step S01 is performed, and the conference terminal actively sends a request to the conference control terminal to obtain the terminal quality information of other conference terminals in the same conference, so as to provide a basis for the subsequent selection of the optimal conference terminal.

[0066] Step S02: receiving and parsing the terminal quality information indication signaling sent by the conference control terminal, obtaining the terminal quality information of at least one conference terminal, and updating the terminal quality information to the terminal list.

[0067] It should be noted that the terminal quality information indication signaling refers to the signaling containing terminal quality information sent by the conference control end to the conference terminal. The terminal quality information includes the conference line status, frame positioning status, and coding quality status, which are used to evaluate the communication quality of the conference terminal. The terminal list refers to the list of all conference terminals in the same conference stored by the conference terminal.

[0068] In addition, it should be noted that the conference terminal receives terminal quality information indication signaling from the conference control end through the terminal protocol processing unit. The signaling includes terminal quality information of at least one other conference terminal. The conference terminal parses the signaling, extracts the conference line status, frame positioning status, and encoding quality status of at least one other conference terminal, and updates these status information to the locally maintained terminal list.

[0069] It is understandable that since existing solutions often only rely on static configuration or simple signal detection to judge communication quality, step S02 is performed to receive terminal quality information indication signaling and parse to obtain terminal quality information of at least one other conference terminal, comprehensively consider multiple quality indicators, improve the accuracy of selection, and provide comprehensive and accurate data support for the subsequent selection of the conference terminal with the best communication quality.

[0070] In a feasible implementation manner, the terminal quality information includes conference line status, frame positioning status, and encoding quality status. In step S02, after the step of updating the terminal quality information to the terminal list, steps A01 to A03 are also included:

[0071] Step A01, upon receiving a conference selection request, searching for each first conference terminal in a terminal list whose conference line status is good, wherein the conference status is determined by the conference control terminal;

[0072] It should be noted that the conference selection request refers to a request initiated by a user or system for selecting a terminal to participate in the conference. The conference line status refers to the status information of the E1 dedicated line, including parameters such as frame signal loss, frame desynchronization and bit error rate. In the conference terminal, the terminal conference control processing unit receives terminal quality information from the conference control end. As the hub of the conference terminal, the terminal conference control processing unit is responsible for receiving and sending various terminal quality information signals. The terminal quality information includes the conference line status, frame positioning status, and encoding quality status of each conference terminal. According to the definition of the E1 dedicated line (good, slightly worse, very worse), the conference terminal with a conference line status of "good" is screened out as the first conference terminal. The first conference terminal refers to the candidate set of conference terminals with a good conference line status screened out from all conference terminals.

[0073] Step A02, searching for each second conference terminal without frame alignment loss in each first conference terminal based on the frame alignment state;

[0074] It should be noted that the frame alignment status refers to the H.221 frame alignment (FAS) status, which ensures the synchronization and accuracy of data transmission. In the first conference terminal candidate set, the terminal conference control processing unit further selects the conference terminal without frame alignment loss (i.e., the FAS status is normal) according to the H.221 frame alignment (FAS) status statistics as the second conference terminal. The second conference terminal refers to the conference terminal candidate set further selected according to the frame alignment status in the first conference terminal.

[0075] Step A03, analyzing the encoding quality status of each second conference terminal, determining each second conference terminal with a resolution higher than a preset resolution threshold, recording them as each target conference terminal, and outputting each target conference terminal.

[0076] It should be noted that the encoding quality status includes information such as video encoding resolution. Based on the encoding quality status information, a conference terminal with a resolution higher than a preset resolution threshold is selected as the target conference terminal in the second conference terminal. The preset resolution threshold is a pre-set video encoding resolution standard used to screen terminals with high encoding quality and perform conference operations such as listening, broadcasting, and viewing on the target conference terminal.

[0077] In this implementation, by screening the first conference terminal with a good conference line status, it is ensured that the subsequent steps are performed in the conference terminal with higher communication quality, thereby avoiding communication interruption or quality degradation caused by line problems. By screening the conference terminals without frame positioning loss, the accurate transmission of audio and video data in the conference is guaranteed, and the user experience is improved. By selecting the conference terminal with a resolution higher than the preset resolution threshold as the target conference terminal, the visual quality of the conference is improved, and the user's demand for high-definition video is met.

[0078] In a feasible implementation manner, the conference line status includes the number of frame signal loss times, the number of frame desynchronization times and the bit error rate. In step A01, before the step of searching the terminal list for each first conference terminal with a good conference line status, steps A11 to A13 are also included:

[0079] Step A11, when the number of frame signal losses is equal to the first signal loss threshold, the number of frame desynchronization is equal to the first frame desynchronization threshold, and the bit error rate is less than the preset bit error rate threshold, it is determined that the conference line state is good;

[0080] It should be noted that the number of frame signal losses refers to the total number of frame signal losses that occur on the E1 dedicated line within a statistical period (such as 1 minute), the number of frame desynchronization refers to the total number of frame desynchronization that occurs on the E1 dedicated line within the statistical period, and the bit error rate refers to the ratio of the number of erroneous bits in the data transmitted on the E1 dedicated line to the total number of bits within the statistical period. The first signal loss threshold (such as 0 times) and the first frame desynchronization threshold (such as 0 times) are threshold indicators for judging whether the line status is good or not, which are pre-set according to the line standard and conference requirements. If within a statistical period, the number of frame signal losses is the first signal loss threshold, the number of frame desynchronization is the first frame desynchronization threshold, and the bit error rate is lower than the preset bit error rate threshold (such as 10 -7 ), the conference line status is determined to be “good”.

[0081] Step A12: when the number of frame signal loss is greater than the first signal loss threshold but less than the second signal loss threshold, the number of frame desynchronization is greater than the first frame desynchronization threshold but less than the second frame desynchronization threshold, and the bit error rate is less than the preset bit error rate threshold, it is determined that the conference line status is slightly poor;

[0082] It should be noted that, similarly, the second signal loss threshold (such as 3 times) and the second frame desynchronization threshold (such as 3 times) are threshold indicators for judging whether the line status is very poor, which are pre-set according to the line standard and conference requirements. If within the statistical period, the number of frame signal losses is greater than the first signal loss threshold and less than the second signal loss threshold, and the number of frame desynchronization is greater than the first frame desynchronization threshold but less than the second frame desynchronization threshold, and the bit error rate is also lower than the preset bit error rate threshold, then the conference line status is judged to be "slightly poor", indicating that although there are some problems with the line, it is still within an acceptable range.

[0083] Step A13: when the number of frame signal losses is greater than the second signal loss threshold, or the number of frame desynchronization is greater than the second preset frame desynchronization threshold, or the bit error rate is greater than the preset bit error rate threshold, it is determined that the conference line status is very bad.

[0084] It should be noted that, within the statistical period, if the number of frame signal losses is greater than the second signal loss threshold, the number of frame desynchronization is greater than the second preset frame desynchronization threshold, or the bit error rate is greater than the preset bit error rate threshold, the conference line status is judged to be "very poor". At this time, the line communication quality has seriously affected the normal progress of the meeting, and immediate measures need to be taken to investigate and repair it.

[0085] In this implementation, by monitoring the three key indicators of frame signal loss times, frame desynchronization times and bit error rate, and setting corresponding threshold conditions, it is possible to accurately determine the state of the conference line. When the conference line is in good condition, the communication quality is high, and the conference participants can communicate clearly and smoothly, thereby improving the efficiency of the meeting. When the conference line is in slightly worse condition, the system can identify minor problems, such as occasional frame signal loss or frame desynchronization, but they have not yet reached the severity of affecting the communication quality. When the conference line is in very poor condition, it indicates that there are serious problems in the conference line, such as frequent frame signal loss, continuous frame desynchronization or high bit error rate, which will seriously affect the communication quality.

[0086] In a feasible implementation manner, the conference terminal information acquisition method further includes steps A21 to A23:

[0087] Step A21, monitoring encoding quality status information;

[0088] It should be noted that the conference terminal continuously monitors the coding quality status information of the conference terminal through the coding processing unit. The coding quality status information refers to the coding status data collected and processed in real time by the coding processing unit during the conference communication process of the venue terminal, such as video coding resolution, audio coding format, etc., which reflects the current coding quality status of the terminal. The coding processing unit is used to count the coding status of the conference terminal and send the coding quality status information to the terminal conference control processing unit.

[0089] Step A22, when receiving a terminal quality status request signaling sent by the conference control terminal or the coding quality status information changes, generating a terminal quality status indication signaling, the terminal quality status indication signaling including the coding quality status information;

[0090] It should be noted that the terminal quality status request signaling refers to the request signaling sent by the conference control terminal to the terminal, which is used to request the encoding quality status information of the conference terminal, and the terminal quality status indication signaling refers to the response signaling sent by the terminal to the conference control terminal, which contains the current encoding quality status information of the terminal. When the conference terminal receives the terminal quality status request signaling sent by the conference control terminal, or when the encoding quality status information changes, it generates the terminal quality status indication signaling, which contains the encoding quality status information of the conference terminal, such as video encoding resolution, etc., and attaches a unique identifier (MT number) to distinguish different conference terminals.

[0091] Step A23: Send the terminal quality status indication signaling to the conference control terminal.

[0092] It should be noted that after generating the terminal quality status indication signaling, the conference terminal sends it to the conference control end through the terminal conference control processing unit.

[0093] In this embodiment, through continuous monitoring, the system can promptly detect changes in encoding quality. By generating and sending terminal quality status indication signaling, the system can ensure that the conference control end can grasp the encoding quality status of each terminal in real time. Through an efficient and reliable transmission mechanism, the system can ensure that the conference control end can promptly receive and update the encoding quality status information of each terminal.

[0094] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 3 , applied to a conference control terminal in a conference system, the conference terminal information acquisition method includes steps S11 to S12:

[0095] Step S11, receiving a terminal quality information request signaling sent by any conference terminal in the conference system;

[0096] It should be noted that the conference control processing unit of the conference control end serves as the hub of the conference control end and is responsible for receiving terminal quality information request signaling from conference terminals. By receiving terminal quality information request signaling, the conference control end can understand which conference terminal needs to obtain terminal quality information of other conference terminals.

[0097] Step S12: Based on the terminal quality information request signaling, a terminal quality information indication signaling is sent to the conference terminal, wherein the terminal quality information indication signaling includes the terminal quality information of at least one conference terminal. The conference terminal is used to receive and parse the terminal quality information indication signaling sent by the conference control terminal, and update the terminal quality information obtained by the parsing to the terminal list.

[0098] It should be noted that after receiving the terminal quality information request signaling, the conference control processing unit of the conference control end will retrieve the corresponding terminal quality information from the terminal quality information database according to the content of the request (it may be a request for the terminal quality information of a specific conference terminal or a request for the terminal quality information of all conference terminals). The terminal quality information database refers to the database used by the conference control end to store and manage the terminal quality information of all conference terminals in the conference. The retrieved terminal quality information is encapsulated into a terminal quality information indication signaling and sent to the conference terminal requesting the information.

[0099] In this embodiment, by receiving request signaling, the conference control end can obtain the terminal's query demand for terminal quality information, and prepare for the subsequent sending of terminal quality information indication signaling. By sending terminal quality information indication signaling, the conference terminal can obtain the terminal quality information of other conference terminals in the same conference, thereby achieving a comprehensive understanding and monitoring of the conference communication quality.

[0100] In a feasible implementation manner, in step S11, after the step of receiving the terminal quality information request signaling sent by any conference terminal in the conference system, steps B01 to B03 are also included:

[0101] Step B01, parsing the terminal quality information request signaling to obtain a terminal identifier;

[0102] It should be noted that the terminal identifier (MT number) is a parameter used to uniquely identify a conference terminal. It consists of two parts: M number and T number. M number is used to identify the conference, while T number is used to identify the conference terminal in the conference. In a video conference involving multiple conference terminals, each conference terminal will be assigned a unique MT number.

[0103] In addition, it should be noted that after receiving the terminal quality information request signaling from the conference terminal, the conference control processing unit of the conference control end parses the terminal quality information request signaling to obtain a terminal identifier for identifying the conference terminal request information.

[0104] Step B02, if the terminal identifier is not a preset identifier, searching the terminal quality information of the conference terminal corresponding to the terminal identifier in the terminal quality information database of the conference control terminal, and generating a terminal quality information indication signaling;

[0105] It should be noted that when the resolved terminal identifier is not a preset identifier (for example, 0), the conference control processing unit of the conference control end searches for the corresponding conference terminal and its terminal quality information in the terminal quality information database based on the terminal identifier. After finding the corresponding information, it encapsulates this information into a terminal quality information indication signaling and prepares to send it to the conference terminal.

[0106] Step B03: If the terminal identifier is a preset identifier, the terminal quality information of each conference terminal in the terminal quality information database of the conference control terminal is determined, and a terminal quality information indication signaling is generated.

[0107] It should be noted that if the resolved terminal identifier is a preset identifier, it means that the conference terminal requesting information hopes to obtain the terminal quality information of all other conference terminals in the conference. In this case, the conference control processing unit of the conference control end traverses the terminal quality information database, collects the terminal quality information of all conference terminals, and encapsulates this information into a terminal quality information indication signaling. This indication signaling will contain the terminal quality information of all conference terminals in the conference, so that the conference terminal requesting information can fully understand the communication quality of other terminals in the conference.

[0108] In this embodiment, by parsing the terminal quality information request signaling, the conference control end can accurately obtain the terminal identifier of the conference terminal request information, which provides a basis for finding and providing terminal quality information in subsequent steps. By utilizing the terminal quality information database, the conference control end can quickly find the terminal quality information corresponding to the conference terminal requested by the conference terminal, and generate a terminal quality information indication signaling containing this information, thereby helping the conference terminal to better understand the communication quality status of other terminals in the conference, and then conduct global communication quality analysis and adjustment to improve the communication quality of the entire conference.

[0109] In a feasible implementation manner, the conference terminal information acquisition method further includes steps B11 to B13:

[0110] Step B11, receiving a terminal quality status indication signaling sent by a conference terminal, and obtaining encoding quality status information of the conference terminal;

[0111] It should be noted that the conference control processing unit of the conference control end receives the terminal quality status indication signaling sent from the conference terminal through the control end protocol processing unit. The control end protocol processing unit is used to receive the terminal quality status indication signaling from the conference terminal, report it to the conference control processing unit of the conference control end, and extract the encoding quality status information from the parsed signaling, and send the encoding quality status information to the terminal quality processing unit. The terminal quality processing unit is used to manage the terminal quality information of the conference terminal and the mapping relationship between the conference terminal and the E1 dedicated line.

[0112] Step B12, detecting the conference line status and frame alignment status of the conference terminal, and integrating the coding quality status information, the conference line status and the frame alignment status into the terminal quality information of the conference terminal;

[0113] It should be noted that in the conference control end, the data framing processing unit is responsible for detecting the conference line status, including frame signal loss (LOS), frame out-of-sync (LFA) and bit error rate information, and sending it to the terminal quality processing unit. The control end protocol processing unit obtains the frame positioning status of the conference terminal by collecting the H221 framing data of the data framing processing unit, and reports the frame positioning status to the terminal quality processing unit. The terminal quality processing unit integrates the coding quality status information, conference line status and frame positioning status. The integrated information constitutes the terminal quality information of the conference terminal, which comprehensively reflects the communication quality status of the conference terminal.

[0114] Step B13: storing the terminal quality information in a terminal quality information database.

[0115] It should be noted that the conference system is provided with a special terminal quality information database for storing and managing the terminal quality information of all conference terminals in the conference, and the conference control processing unit stores the integrated terminal quality information in the terminal quality information database.

[0116] In this embodiment, by receiving and parsing the terminal quality status indication signaling, the conference control end can obtain the coding quality status information of the conference terminal in real time. By comprehensively detecting and integrating the conference line status and frame positioning status of the conference terminal, it can more comprehensively understand the communication quality status of the conference terminal. By establishing a terminal quality information database, the conference control end can efficiently store and manage this information, providing strong support for conference control selection in the conference terminal.

[0117] For example, to help understand the technical concept or technical principle of this application, please refer to Figure 4 , Figure 5 and Figure 6 , Figure 4 Provides a schematic diagram of the conference control end in the conference terminal information acquisition system. Figure 5 Provides a schematic diagram of conference terminals in the conference terminal information acquisition system. Figure 6 Provides a sequence diagram of terminal quality information signaling exchange between conference terminals and conference control terminals.

[0118] exist Figure 4In the embodiment, A is a conference control terminal, B is a conference terminal, and the terminal quality information signaling includes a terminal quality status request signaling, a terminal quality status indication signaling, a terminal quality information request signaling, and a terminal quality information indication signaling. The conference control terminal A interacts with the conference terminal B through the control terminal protocol processing unit. The conference terminal B sends the terminal quality status indication signaling and the terminal quality information request signaling to the control terminal protocol processing unit of the conference control terminal A. The control terminal protocol processing unit reports the received terminal quality status indication signaling and the terminal quality information request signaling to the conference control processing unit of the conference control terminal A. The terminal quality status indication signaling is returned by the conference terminal B after the conference control terminal A sends the terminal quality status request signaling to the conference terminal B. Coding quality status information, the conference control processing unit updates the corresponding coding quality status information of conference terminal B according to the terminal quality status indication signaling. For the terminal quality information request signaling, the conference control processing unit parses and returns the terminal quality information indication signaling, which includes the terminal quality information requested by the conference terminal B. The conference control processing unit obtains the terminal quality information through the terminal quality processing unit. The terminal quality processing unit collects the conference line status of the conference terminal through the data framing processing unit, and collects the H221 framing data of the data framing processing unit through the control end protocol processing unit, thereby obtaining the frame positioning status, and receives the coding quality status information of the conference terminal B through the control end protocol processing unit, thereby determining the terminal quality information.

[0119] exist Figure 5 In the process, conference control terminal A interacts with conference terminal B through the terminal protocol processing unit. The terminal protocol processing unit reports the received terminal quality status request signaling and terminal quality information indication signaling to the terminal conference control processing unit. For the terminal quality status request signaling, conference terminal B generates a terminal quality status indication signaling based on the encoding quality status information of the conference terminal through the encoding processing unit, and sends it to conference control terminal A through the terminal conference control processing unit. The terminal quality information indication signaling is the signaling returned by conference control terminal A after conference terminal B sends a terminal quality information request signaling to conference control terminal A for requesting terminal quality information of other conference terminals, which includes the terminal quality information of other conference terminals requested by conference terminal B. Conference terminal B updates the parsed terminal quality information for subsequent selection and control of terminals.

[0120] exist Figure 6In the process, the conference control end sends a terminal quality status request signaling to the conference terminal to request the encoding quality status information of the conference terminal. The conference terminal returns a terminal quality status indication signaling, which includes the corresponding encoding quality status information. When the encoding quality status information of the conference terminal changes, the conference terminal will also actively send a terminal quality status indication signaling to the conference control end, including the changed encoding quality status information, which is used to update the terminal quality information stored in the conference control end. The conference terminal sends a terminal quality information request signaling to the conference control end to request the terminal quality information stored in the conference control end. After receiving the terminal quality information request signaling, the conference control end returns a terminal quality information indication signaling, which includes the terminal quality information requested by the conference terminal.
