All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative work are within the scope of the present invention.

In an embodiment of the invention: the media controller instructs the media processor to add at least one mixer endpoint, and sends a topology descriptor between the user endpoint and the mixer endpoint to the media processor to notify the media processor to establish a session The connection enables the media processor to add a Mix endpoint when establishing a session connection, thereby enabling timely reservation of conference resources.

The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

As shown in FIG. 2, the system for establishing a tongue connection in the separation architecture of the embodiment of the present invention includes: a media controller 10 and a media processor 20.

The media controller 10 is connected to the media processor 20, and is used to refer to when the session connection needs to be established. The media processor 20 adds at least one mixer endpoint, instructs the media processor 20 to add a user endpoint based on the session type, and indicates to the media processor 20 a topological relationship between the user endpoint and the mixer endpoint.

The media controller 10 can also place a topological relationship between the user endpoint and the mixer endpoint in an indication to increase the user endpoint.

The media processor 20 is coupled to the media controller 10 for receiving at least one mixer endpoint after receiving an indication from the media controller 10 to add at least one mixer endpoint, receiving an increase from the media controller 10. After the indication of the user endpoint, the user endpoint is added, and a topology connection between the user endpoint and the mixer endpoint is established based on the topology relationship received from the indication from the media controller 10.

In the embodiment of the present invention, when establishing a session connection, the media controller 10 instructs the media processor 20 to add a mixer endpoint, that is, the media processor 20 does not need to increase the Mix when added to the third user endpoint, that is, Both ordinary calls and conferences are combined and transmitted through the mixer endpoints, so that the conference can be specially processed to meet different requirements.

As shown in FIG. 3, the structure of the media controller of the embodiment of the present invention includes: a first indication module 100 and a second indication module 110.

The first indication module 100 is coupled to the second indication module 110 for instructing the media processor 20 to add at least one mixer endpoint when a session connection needs to be established.

Among them, increasing the number of mixer endpoints can be set according to the needs of the session connection, or can be set in advance.

The second indication module 110 is coupled to the first indication module 100 for instructing the media processor 20 to add a user endpoint according to the session type, and indicating to the media processor 20 a topological relationship between the user endpoint and the mixer endpoint.

The second indication module 110 may further include: a processing module 1100 and a sending module 1110.

The processing module 1100 is configured to determine a topology descriptor between the user endpoint and the mixer endpoint according to the session type.

The sending module 1110 is configured to instruct the media processor 20 to add a user endpoint, and instruct the media processor 20 to indicate a topology descriptor between the user endpoint and the mixer endpoint determined by the processing module 1100 and an identifier of the mixer endpoint. In this embodiment, the processing module 1100 may indicate the number of user endpoints added by the media processor 20 according to the conference requirement, and assign a corresponding identifier to each user endpoint; and determine each user endpoint and the remix according to the conference requirement. The topology descriptor connected between the endpoints of the device, and the topology structure corresponding to the topology descriptor includes but is not limited to one or more of the following structures:

Two-way structure, one-way structure, isolated structure, and so on.

The processing module 1100 can also instruct the media processor 20 to add only one user endpoint at a time, and continuously instruct the media processor 20 to add user endpoints based on an increase in the number of users in the conference.

Since the mixer endpoint is connected to more than one user endpoint and is connected differently to each user endpoint, each additional user endpoint needs to carry a topology descriptor between the user endpoint and the mixer endpoint.

The media controller 10 may further include: an adding module 120.

The adding module 120 is connected to the first indicating module 100 for allocating and adding the identifier of each mixer end point and the data stream type corresponding to each mixer end point in the indication of the first indicating module 100.

Further, the identity of the assigned mixer endpoint needs to be multiplexed with the existing time division (Time

Division Multiple, TDM) endpoints, IP endpoints, and Asynchronous Transfer Mode (ATM) endpoint naming rules are different to avoid collisions.

Data stream types include, but are not limited to, one or more of the following data streams:

Audio streams, video streams, and more.

The media controller 10 may further include: a third indication module 130.

The third indication module 130 is connected to the first indication module 100 and the adding module 120, and is configured to: if the first indication module 100 instructs the media processor 20 to add at least two mixer endpoints, and the connection between the mixer endpoints is required, Then, after the media processor 20 adds at least two mixer endpoints, the identity of each mixer endpoint to be connected, and the topology descriptor between the mixer endpoints to the media processor are established before the session connection is established. send.

Further, since the session needs to be connected between the mixer endpoints, for example, in the SideBar conference, the main site and the sub-site need to be distinguished. In this case, a mixer endpoint needs to be added to the main site. Adding a mixer endpoint and having a connection between the two mixer endpoints requires that the media processor 20 be instructed to establish a corresponding session connection. The media controller 10 may further include: a storage module 140.

The storage module 140 is connected to the second indication module 110, and is configured to establish and save a correspondence between the mixer endpoint and the identifier after receiving the indication response message from the media processor 20 carrying the identifier of the mixer endpoint.

Further, if only one mixer endpoint needs to be added in the conference connection, the media controller

10 may not assign an identifier to the mixer endpoint, and the media processor 20 assigns an identifier to the mixer endpoint; of course, the media controller 10 may also assign an identifier to the mixer endpoint.

If only at least two mixer endpoints are added to the conference connection, the assignment must be made by the media controller 10, because if assigned by the media processor 20, the media controller 10 does not know which identifier is associated with which mixer endpoint. Correspondingly, the media controller 10 and the media processor 20 are not unified, and the session connection cannot be completed.

As shown in FIG. 4, the structure of the media processor of the embodiment of the present invention includes: a first receiving module 200 and a second receiving module 210.

The first receiving module 200 is coupled to the second receiving module 210 for increasing the mixer endpoint based on the received indication from the media controller 10 to add at least one of the mixer endpoints.

Mixer endpoint.

The allocation module 2010 is configured to use the identifier in the indication as an identifier of the added mixer endpoint. The second receiving module 210 is connected to the first receiving module 200, and is configured to add a user endpoint according to the received indication from the media controller 10 to increase the user endpoint, and according to the received indication from the media controller 10 A topological relationship between the user endpoint and the mixer endpoint establishes a topological connection between the user endpoint and the mixer endpoint.

The second receiving module 210 may further include: an adding module 2100 and a second establishing module 2110.

The adding module 2100 is configured to: according to the received increase of the user endpoint from the media controller 10 Interest, increase the user endpoint.

The second establishing module 2110 is configured to establish, according to the received topology descriptor between the user endpoint and the mixer endpoint in the indication from the media controller 10, the added user terminal and the identifier corresponding to the identifier A topological connection between the endpoints of the sounder.

The media processor may further include: a third establishing module 220.

A descriptor that determines each of the corresponding mixer endpoints and establishes a topological connection between the mixer endpoints.

The media processor may further include: a response module 230.

The response module 230 is connected to the first receiving module 200, and is configured to: if the indication received by the first receiving module 200 does not carry the identifier of the mixer endpoint, add an identifier to the added mixer endpoint of the adding module 2100, and An indication response message carrying the identity is returned to the media controller 10.

As shown in FIG. 5A, the method for establishing a tongue connection under the separation architecture of the embodiment of the present invention includes the following steps:

Step a500: The media controller instructs the media processor to add at least one mixer endpoint when a session connection needs to be established.

The step a500 may further include:

When the media controller needs to establish a session connection, each of the mixer endpoints is assigned a corresponding identifier, and the identifier of each mixer endpoint and each mixer endpoint are carried in the indication of adding at least one mixer endpoint. The corresponding data stream type.

In this embodiment, the data stream type includes but is not limited to one or more of the following modes: an audio stream, a video stream, and the like.

It is possible to select which data stream each mixer endpoint needs to support based on the needs of the tongue. It is possible that one mixer endpoint supports only one data stream, and it is also possible that one mixer endpoint supports multiple data streams.

Step a501: The media controller instructs the media processor to add a user endpoint, and indicates to the media processor a topology relationship between the user endpoint and the mixer endpoint, and notifies the media processor to establish a session connection.

The media controller can also place a topology relationship between the user endpoint and the mixer endpoint in an indication to increase the user endpoint.

The step a501 may further include: After the media processor adds the mixer endpoint, the media controller determines the number of required user endpoints based on the session type, and a topology descriptor between each user endpoint and the mixer endpoint, instructing the media processor to increase the determined number User endpoint indicating to the media processor a topology descriptor between the user endpoint and the mixer endpoint, and the identity of the mixer endpoint.

Of course, the media controller can instruct the media processor to add only one user endpoint, and cyclically instruct the media processor to add a user endpoint, or instruct the media processor to add multiple user endpoints. As the number of users increases, the media controller can continue to let the media processor increase the user endpoint after the session is established.

The step a500 and the step a501 may further include:

The media processor receives an indication of adding at least one mixer endpoint to add at least one mixer endpoint.

In this embodiment, the media processor may further include: according to the received indication that the at least one mixer endpoint is added, the at least one mixer endpoint may further include:

After the media processor receives an indication from the media controller to add at least one mixer endpoint, the mixer endpoint supporting the data stream type is added according to the data stream type corresponding to the mixer endpoint in the indication;

The identification in the indication is taken as the identification of the added mixer endpoint.

For example: Add a mixer endpoint that supports voice streaming, and indicate that the voice stream corresponding to the voice is Mixl, then Mixl is used as the identifier of the mixer endpoint.

The step a501 may further include:

The media processor adds the user endpoint according to the received indication of increasing the user endpoint, and establishes a topology connection between the user endpoint and the mixer endpoint according to the topology relationship in the received indication.

In this embodiment, after receiving the indication of increasing the user endpoint, the media processor adds the user endpoint, and establishes a topology connection between the user endpoint and the mixer endpoint according to the topology relationship in the received indication. Can further include:

After receiving the indication from the media controller to increase the user endpoint, the media processor increases the corresponding number of user endpoints according to the quantity in the indication;

A topology connection between the added user endpoint and the mixer endpoint corresponding to the identifier is established based on the topology descriptor between the user endpoint and the mixer endpoint in the received indication. If multiple user endpoints need to be added at a time, the media controller needs to send the identifier of the assigned user endpoint to the media processor, and the media processor distinguishes according to the identifier of the received user endpoint, and adds a corresponding user endpoint; If a user endpoint is added at a time, the identity of the user endpoint may be assigned by the media controller or by the media processor.

ϋ殳 Two user endpoints T1 and Τ2 need to be added. The topology corresponding to the topology descriptor between Mixl and the two user endpoints is a unidirectional structure. Then the media processor first adds two user endpoints and respectively sets T1. And T2 is assigned to two user endpoints. Mixl finds the corresponding mixer endpoint and sets the topology between the mixer endpoint and T1 and T2 to a one-way structure to complete the session establishment.

Wherein, if the media controller instructs the media processor to add at least two mixer endpoints, and the connection between the mixer endpoints is required, step a501 may further include:

The media controller will send the identity of each mixer endpoint that needs to be connected, along with the topology descriptor between the mixer endpoints, to the media processor.

The media controller may place the above information in a message carrying the bearer information of the H.248 protocol, and send the information to the media processor, for example: add (ADD) message, modify (MODIFY) message, move (MOVE) message, and the like.

After the media processor establishes a topology connection between each user endpoint and the mixer endpoint, it also needs to determine the corresponding each mixer endpoint according to the identifier of each mixer endpoint, according to the mixer endpoint. The topology descriptor establishes a topological connection between the determined mixer endpoints.

If, in step a500, the media controller instructs the media processor to add a mixer end point, and does not carry the identifier of the mixer end point in the indication, after step a500, step a501 may further include:

The media processor assigns an identifier to the added mixer endpoint and returns an indication response message carrying the identifier to the media controller;

Then, after receiving the indication response message, the media controller establishes and saves a correspondence between the mixer endpoint and the identifier.

Further, the media processor may use the Bearer characteristics package defined in the International Telecommunication Union-Transmission (ITU-T) Q.1950 to assign an identifier to the "Quencher Endpoint" The comparison port is implemented by extending the eigenvalues of the bearer network attribute (BNC), as shown in the following table: BNC eigenvalue Q.765.5 Binary coded text encoding ( Characteristic encoding ) ( binary encoding ) ( Text encoding )

Mixer 0x0 IFF Mix In this embodiment, the media controller and the media processor interact using the H.248 protocol. The media controller may send the indication to the media processor in a message carrying the bearer information of the H.248 protocol, such as: add (ADD) message, modify (MODIFY) message, move (MOVE) message, etc.; media After receiving the indication message, the processor needs to return an indication response message to the media controller. If it is an Add Request message, the media processor returns a Add Resp message to the media controller.

As shown in FIG. 5B, the method for cyclically increasing user endpoints in the separation architecture of the embodiment of the present invention includes the following steps:

Step b500: When the media controller needs to establish a session connection, the instruction to add a mixer endpoint is placed in the add message and sent to the media processor.

The media controller can also notify the media processor to add multiple mixer endpoints.

Step b501: The media processor adds a mixer endpoint according to the added message, and returns an add response message to the media controller.

Step b502: The media controller determines, according to the session type, a topology descriptor between the user endpoint and the mixer endpoint that needs to be added, and places the determined topology descriptor and the instruction for adding the user endpoint into the add message, The media processor sends.

Step b503: The media processor adds a user endpoint according to the added message, and establishes a topology connection between the user endpoint and the mixer endpoint according to the topology descriptor in the added message, and returns a response message to the media controller. .

Steps b502 and b503 are continued, until all user endpoints are added, and all connections to the mixer endpoint are established, the session establishment ends.

As shown in FIG. 6A, in the schematic diagram of the audio stream connection model of the embodiment of the present embodiment, T1, T2, T3, T4 and T5 are different user endpoints, wherein T1 to T3 are in the conference field, and T4 and T5 are small. In the conference hall, users in the small conference hall can hear the voice of the conference site users, but the users of the conference venue cannot hear the voice of the small conference site users, which requires a one-way junction between the two mixer endpoints. The connection is made, and the two-way structure is used between the user endpoint and the mixer endpoint.

As shown in FIG. 6A, in the schematic diagram of the video stream connection model of the SideBar in the embodiment of the present invention, the user T1 who hosts the conference needs to let each user participating in the conference see his/her own image, but does not need to see other users participating in the conference. Image, which requires a one-way structure between the user endpoint and the mixer endpoint.

In the implementation process, FIG. 6A and FIG. 6B need to be used in combination, and the specific implementation process is shown in FIG. 6C. In the embodiment of the present invention, each mixer end point can be placed in the same context, so that FIG. 6A and FIG. 6B can be performed in the same SideBar, that is, the audio stream is required to perform SideBar conference, video stream. Performing a non-SideBar conference; the embodiment of the present invention can completely implement an audio stream for a non-SideBar conference and a video stream for a SideBar conference.

As shown in FIG. 6D, in the second model diagram of the SideBar conference in the embodiment of the present invention, since the mixer endpoint can support multiple different types of data streams, the audio mixer endpoint Mix1 in FIG. 6A can be performed simultaneously. The audio stream is transmitted at the same time, and the video stream is transmitted at the same time, thereby saving resources. Of course, the audio mixer endpoint Mix2 end point in FIG. 6A can also perform audio stream transmission and video stream transmission.

It can be seen from the foregoing embodiment that the media controller in the embodiment of the present invention instructs the media processor to add at least one mixer endpoint when it is required to establish a tongue connection; instructing the media processor to add a user endpoint to indicate the user a topology relationship between the endpoint and the mixer endpoint, informing the media processor to establish a session connection, so that when the session is established, a portion of the session resources can be reserved in time, and the media controller knows the Mix added by the media processor Endpoint, so the media controller can send the shared attribute to the Mix endpoint, which reduces the network burden and the amount of information. Since the SideBar can be implemented through the Mix endpoint, only one context needs to be established, thus enabling audio and video streams. Inconsistent situation.
