When the first MCU system receives the first roll call request, a first called terminal identification in the first roll call request is obtained, and first media data corresponding to the chairman terminal identification are sent to MCU systems except the first MCU system step by step until the first media data are sent to a second MCU system connected with the first called terminal.

Further, the first MCU system obtains a first called terminal identifier of the first called speech request, and when it is determined that the first called terminal identifier is an identifier of a terminal connected to the first MCU system, that is, when the second MCU system is the first MCU system, the first media data corresponding to the chairman terminal identifier is sent to the first called terminal corresponding to the first called terminal identifier.

The first utterance instruction is used for instructing the first named terminal to acquire utterance data. Wherein the speech data may be at least one of video data, voice data, text data, and the like. When the speech data is video data, the first called terminal can open the camera according to the first speech instruction and acquire the video data; when the speech data is voice data, the first named terminal may turn on a voice receiver according to the first speech instruction and receive the voice data. The voice receiver refers to an electronic device that receives voice.

When roll calling and speaking are carried out on a first called terminal in a cross-level conference, roll calling and speaking can be carried out on the first called terminal only by acquiring a first roll calling request through an MCU system connected with a chairman terminal, and management personnel at each level are not required to carry out roll calling and speaking operation on the terminal, so that the efficiency of roll calling and speaking of the cross-level conference is improved.

In one embodiment, each MCU system comprises a first server and a second server; when a first MCU system connected with a chairman terminal acquires a first click comment request, the first click comment request is sent to other MCU systems except the first MCU system step by step, and the method comprises the following steps: when a first server in a first MCU system connected with a chairman terminal acquires a first click speech request, the first click speech request is sent to first servers in other MCU systems except the first MCU system step by step.

Each MCU system may include a first server and a second server, where the second server may be a server cluster composed of a signaling server and a media server, or may be an integrated server integrating a signaling service function and a media service function, but is not limited thereto. The signaling server may be configured to process the signaling, such as generating the signaling, receiving, sending, deleting, modifying, and the like, but is not limited thereto.

The first server may be a background server that handles the roll call origination request. The first server may process the first place name speaking request, such as receiving, sending, deleting, modifying, and the like, but is not limited thereto.

When a first server in a first MCU system connected with a chairman terminal acquires a first roll call request, a first called terminal identifier in the first roll call request can be acquired, and the position of the first called terminal identifier in the cascaded MCU system is judged. And the first server in the first MCU system sends the first roll-call request to the first server of the higher-level MCU system step by step upwards and sends the first roll-call request to the first server of the lower-level MCU system step by step downwards.

The chairman terminal identification of the chairman terminal is obtained through the first MCU system, and according to the first roll call request, the first media data corresponding to the chairman terminal identification are sent downwards step by step to the second MCU system connected with the first roll call terminal, and the method comprises the following steps: and acquiring a chairman terminal identifier of a chairman terminal through a second server in the first MCU system, and gradually sending first media data corresponding to the chairman terminal identifier to a second server in a second MCU system connected with a first called terminal according to a first calling speaking request sent by a first server in the first MCU system.

The second server in the first MCU system obtains the first roll call request sent by the first server, may obtain the first called terminal identifier from the first roll call request, and determines the position of the first called terminal identifier in the cascaded MCU system. Specifically, in addition to storing the connected terminal identifier in the first MCU system, the terminal identifier connected in the lower MCU system is also stored. And matching the first called terminal identification with the terminal identification stored in the first MCU system, so as to find the position of the first called terminal in the first MCU system or the lower MCU system. When the first called terminal identifier is not matched in the first MCU system, the first called terminal may be used as a terminal connected to the higher-level MCU system.

It should be noted that any MCU system in the cascaded MCU systems stores the terminal id connected to the MCU system and the terminal id connected to the lower MCU system. Therefore, the method can be applied to determine whether the first called terminal identifier is a terminal connected to the MCU system, or a terminal connected to a lower MCU system, or a terminal connected to a higher MCU system.

And when the second server in the first MCU system judges that the first called terminal is the terminal connected with the superior MCU system, the first media data corresponding to the chairman terminal identification is sent to the second server in the MCU system of the previous level. After receiving the first media data, the second server of the MCU system in the previous level also determines the position of the first called terminal in the cascaded MCU system according to the first called terminal identifier in the first called speech request until the first media data is sent to the second server in the second MCU system to which the first called terminal is connected.

And when the second server in the first MCU system judges that the first called terminal is a terminal connected with the lower-level MCU system, transmitting the first media data corresponding to the chairman terminal identification to the second server in the next-level MCU system. After receiving the first media data, the second server of the MCU system of the next level also judges the position of the first called terminal in the cascade MCU system according to the first called terminal identification in the first calling speaking request until the first media data is sent to the second server in the second MCU system connected with the first called terminal.

In a cross-level conference, at least two levels of conferences are involved. Each stage at least comprises one MCU system, namely the cascaded MCU system comprises at least two stages of MCU systems. It should be noted that each MCU system can only have one connected higher-level MCU system, and can have multiple connected lower-level MCU systems.

It can be understood that the resources of the MCU system are limited, and when the MCU system processes both the roll call and the speech request and the media data of each terminal, including video data, voice data, etc., the processing speed of the MCU system is easily reduced and errors are easily made. Therefore, the equipment for processing different functions in the MCU system is used as different servers for carrying out cooperative processing, the processing speed of the whole cross-level conference system can be improved, and the accuracy is improved.

In one embodiment, when a first MCU system connected to a chairman terminal acquires a first click speech request, the step of sending the first click speech request downward to other MCU systems except the first MCU system includes:

step 502, when the first MCU system connected to the chairman terminal acquires the first floor call request, the first floor call request is sent to the next level MCU system and the previous level MCU system connected to the first MCU system.

After acquiring the first roll speech request, the first MCU system sends the first roll speech request to all MCU systems in the cascaded MCU systems, namely all MCU systems of an upper level and all MCU systems of a lower level of the first MCU system.

Further, after acquiring the first roll speech request, the first server in the first MCU system sends the first roll speech request to the first servers of all MCU systems in the cascaded MCU system, that is, the first servers of all MCU systems of the upper level and the first servers of all MCU systems of the lower level of the first MCU system.

And step 504, when the MCU system in the next level acquires the first click comment request, taking the MCU system in the next level as an intermediate MCU system, and sending the first click comment request to the MCU systems in the next level connected with the intermediate MCU systems.

In this embodiment, the first MCU system sends the acquired first named speech request to the next-level MCU system and the previous-level MCU system connected to the first MCU system, the next-level MCU system is used as the intermediate MCU system, and the intermediate MCU sends the first named speech request to the connected next-level MCU system; the MCU system at the upper level is used as an intermediate MCU system, the first roll call request is sent to the connected MCU system at the upper level through the intermediate MCU, the first roll call request can be sent to all MCU systems in the cross-level conference, and the accuracy of roll call of the cross-level conference is improved.

In one embodiment, the above-mentioned cross-level conference roll-call speaking method further includes:

step 602, taking the MCU in the cascaded MCU system that has acquired the first roll call request as a target MCU system, determining whether the first named terminal is connected to the target MCU system, modifying the first named terminal identifier in the first roll call request of each target MCU system according to the determination result, and taking the modified first roll call request as a second roll call request.

In the cascaded MCU system, when a target MCU system acquires a first roll speech request, namely when the target MCU system receives the first roll speech request sent by a superior MCU system, a first roll terminal identifier in the first roll speech request is acquired. And judging whether the first called terminal is connected with the target MCU system or not according to the first called terminal identifier.

And storing the reference identification of the terminal connected with the target MCU system in the target MCU system, and matching the first called terminal identification with the reference identification one by one. And when the matching is successful, judging that the first called terminal is connected with the target MCU system. And when the matching is unsuccessful, judging that the named terminal is not connected with the target MCU system.

It can be understood that, in the cross-level conference, when the first called terminal is not connected to the target MCU system, the target MCU system cannot directly send the first media data corresponding to the chairman terminal identifier to the first called terminal. Therefore, the target MCU system needs to modify the first named terminal identifier in the first named after request and use the modified first named after request as the second named after request.

According to the first roll call request, first media data corresponding to the chairman terminal identification are sent downwards step by step to a second MCU system connected with a first roll call terminal, and the method comprises the following steps:

and step 604, according to the second roll call speaking request, sending the first media data corresponding to the chairman terminal identification to a second MCU system connected with the first roll call terminal step by step.

Generating a first speaking instruction according to the received first roll-call speaking request through a second MCU system, wherein the generating of the first speaking instruction comprises the following steps:

and 606, generating a first speaking instruction according to the received second roll call speaking request through the second MCU system.

And after receiving the second roll call speaking request, the second MCU system generates a first speaking instruction according to the second roll call speaking request. The first utterance instruction can be used for instructing to open a voice receiver connected with the first called terminal and sending the voice data received by the first called terminal to the second MCU system; or the first utterance instruction may be used to instruct the first roll-call terminal to turn on the camera and send the acquired video data to the second MCU system, which is not limited thereto. The second MCU system sends the second media data sent by the first called terminal to the first MCU system step by step, and then the first MCU system sends the second media data of the first called terminal to the chairman terminal.

In this embodiment, it is determined whether the first named terminal is connected to the target MCU, the first named terminal identifier in the first named-speaking request is modified according to the determination result, and the modified first named-speaking request is used as the second named-speaking request. According to the second roll call speaking request, the first media data can be sent to the modified first roll call terminal identification, and the modified first roll call terminal identification can be a cascade gateway at an upper level or a lower level, so that interaction of video data among different MCU systems is realized.

In one embodiment, modifying the first named terminal identifier in the first named-to-speak request of each target MCU system according to the determination result includes: when the first called terminal is connected with the target MCU system, the first called terminal identification is used as a second called terminal identification; and when the first called terminal is disconnected with the target MCU system, acquiring the MCU system connected with the first called terminal, and modifying the first called terminal identifier in the first called speaking request according to the MCU system connected with the first called terminal.

When the first called terminal is connected with the target MCU system, the target MCU system can send the first media data corresponding to the chairman terminal identification to the first called terminal, so that the first called terminal identification in the first calling speech request does not need to be modified, and the first called terminal identification is used as a second called terminal identification.

When the first called terminal is disconnected with the target MCU system, the target MCU system cannot directly send the first media data corresponding to the chairman terminal identification to the first called terminal. Therefore, the first named terminal identification in the first named after-speak request needs to be modified. And acquiring the MCU system connected with the first named terminal through the target MCU system, and modifying the first named terminal identifier in the first named speech request according to the MCU system connected with the first named terminal.

In this embodiment, by judging whether the first called terminal identifier is connected to the target MCU system, when the first called terminal is not connected to the target MCU system, the MCU system to which the first called terminal is connected is acquired, and the first called terminal identifier in the first call request is modified according to the MCU system to which the first called terminal is connected, so that the first media data corresponding to the chairman terminal identifier can be more accurately sent to the first called terminal.

In one embodiment, modifying the identity of the first named terminal in the first named-talk request according to the MCU system to which the first named terminal is connected includes:

and 702, when the MCU system connected with the first named terminal is the upper level of the target MCU system, modifying the first named terminal identifier in the first named speaking request into a first analog terminal identifier and using the first analog terminal identifier as a second named terminal identifier, wherein the first analog terminal is used for connecting the target MCU system with the MCU system at the upper level.

The MCU systems of different levels can carry out the interaction of media data through the analog terminal in the cascade gateway. In the hierarchical network gateway, at least one pair of analog terminals may be included. A pair of analog terminals, namely a first analog terminal and a second analog terminal.

And data sharing is carried out between the pair of the first analog terminal and the second analog terminal. For example, when a first analog terminal receives video data a, a second analog terminal also receives video data a at the same time; when the second analog terminal receives the video data B, the first analog terminal also receives the video data B at the same time, and the first analog terminal and the second analog terminal can receive and send different data at the same time.

In the target MCU system, the identification of the upper terminal of the target MCU system is not stored. And when the first called terminal identification in the first roll call request is not matched with the reference identification stored in the target MCU system, the first called terminal is not connected with the target MCU system and is not in a lower terminal of the target MCU system.

Therefore, the first named terminal is a superior terminal or a terminal connected to other MCU systems except for the target MCU system in the same level. Through the superior MCU system connected with the target MCU system, the media data interaction between the target MCU system and the superior MCU system or the MCU systems in the same level except the target MCU system can be realized. And modifying the first named terminal identification in the first named speaking request into a first analog terminal identification and using the first analog terminal identification as a second named terminal identification.

Step 704, when the MCU system connected to the first named terminal is a subordinate of the target MCU system, modifying the first named terminal identifier in the first named utterance request to a second analog terminal identifier and using the second analog terminal identifier as the second named terminal identifier, where the second analog terminal is used for connecting the target MCU system to a next-level MCU system.

In the target MCU system, reference identifiers of terminals connected with the target MCU system are stored, and reference identifiers of all terminals of a subordinate stage of the target MCU system are also stored. The first called terminal identification is matched with the reference identifications of all terminals of the lower level of the target MCU system one by one, when the matching is successful, a second MCU system connected with the first called terminal can be obtained, and the first called terminal identification in the first calling speech request is modified into a second simulation terminal identification and serves as a second called terminal identification.

In this embodiment, when the first named terminal is a superior terminal of the target MCU system, the first named terminal identifier in the first named-speaking request is modified to be the first analog terminal and serves as the second named terminal identifier; when the first called terminal is a subordinate terminal of the target MCU system, the first called terminal identification in the first calling speaking request is modified into the identification of the second simulation terminal and is used as the second called terminal identification, and the first media data corresponding to the chairman terminal identification can be more accurately sent to the first called terminal step by step.

The target MCU system can search the second MCU system connected with the first called terminal identification and the superior MCU system connected with the second MCU system according to the first called terminal identification, and by analogy, a hierarchical structure chain from the target MCU system to the first called terminal can be formed. For example, the target MCU system is a secondary MCU system 1, and the hierarchical chain may be a secondary MCU system 1-a tertiary MCU system 2-a quaternary MCU system 3 (a second MCU system) -a first called terminal.

The target MCU system can determine the MCU system in the hierarchical structure chain from a plurality of connected lower-level MCU systems according to the hierarchical structure chain, and transmits the first media data to a second analog terminal connected with the MCU system until the first media data are transmitted to the second MCU system step by step.

Meanwhile, in order to avoid interference of voice data of other terminals in the cross-class conference, it is necessary to perform a call closing operation on other terminals except for the chairman terminal and the first called terminal.

In the cascade gateway 904, the second analog terminal 2 is connected to the primary MCU system, and the first analog terminal 2 is connected to the secondary MCU system 2.

When the chairman terminal is the first-stage terminal 1 and the first called terminal is the second-stage terminal 2, the first MCU system is the first-stage MCU system, and the second MCU system is the second-stage MCU system 1. And the first server in the first-level MCU system sends the acquired first click-to-speak request to the second-level MCU system 1 and the second-level MCU system 2 in the next level which are connected with each other.

When the first-level MCU system obtains the first roll call request, the first roll call terminal is obtained to be a lower-level terminal and a terminal connected with the second-level MCU system 1, the first roll call terminal identification in the first roll call request is modified into the second roll call terminal identification, namely the identification of the second simulation terminal 1, and the modified first roll call request is used as the second roll call request.

And the primary MCU system sets a terminal corresponding to the second called terminal identification to receive the first media data, and other terminals except the terminal corresponding to the second called terminal identification receive the second media data. And sending the first media data of the primary terminal 1 to a second called terminal identifier, namely a second analog terminal 1. In the cascade gateway, data are shared between the first analog terminal and the second analog terminal. Therefore, the first analog terminal 1 also receives the first media data of the primary terminal 1 at the same time, and sends the first media data to the secondary MCU system 1.

When the secondary MCU system 1 acquires the first media data of the chairman terminal, the first media data is sent to the secondary terminal 2, and the first called terminal acquires the media data of the chairman terminal, such as video pictures, voice data and the like.

The second-level MCU system 1 sends the second media data to other terminals except the terminal corresponding to the second roll-call terminal identifier, namely a second-level terminal 1 and a first analog terminal 1. When the first analog terminal 1 receives the second media data, the second analog terminal 1 also receives the second media data and sends the second media data to the first-stage MCU system.

When the first-level MCU system receives the second media data, the second media data are sent to other terminals except the terminal corresponding to the second called terminal identification, namely the second analog terminal 2, the first-level terminal 1 and the first-level terminal 2, so that the chairman terminal can obtain the first called terminal media data, such as video pictures, voice data and the like.

The I frame and the P frame exist in the video media stream, the I frame contains complete picture data and can be directly decoded and played through a terminal, and the P frame contains changed partial picture data and can be decoded and played only by depending on the I frame data. The video encoder in the second server may generate an I-frame at intervals, such as 2 seconds per I-frame, or only one of the 50 frames may be an I-frame. When the terminal receives the screen switching instruction, the screen is switched immediately, for example, the terminal is switched from the screen a to the screen B immediately, and the terminal cannot receive the I frame of the screen B immediately, that is, when the call-calling-speaking request is received, the terminal cannot completely display the video screen of the first called terminal or the video screen of the chairman terminal immediately.

In order to avoid the phenomena of screen jamming or screen blacking and the like in the switching process, after the terminal receives the switching instruction, the terminal can continue to play the picture A and wait until the I frame of the picture B is acquired. The maximum time to wait is the I-frame generation interval of the video encoder in the second server, which is typically 2 seconds by default. When the terminal receives the I frame of the picture B, the picture A can be switched into the picture B, and the terminal can be smoother and smoother when pictures are switched.
