The core idea of an embodiment of the method of the present invention is to: insert a media sending request carrying media type information into the queue; when it is necessary to issue a media sending permission, schedule the media sending request carrying media type information from the queue according to the preset scheduling policy Media sends request.

Figure 5 is a flow chart for implementing an embodiment of the method of the present invention. Referring to Figure 5, in an embodiment of the present invention, media sending requests of multiple media types are managed, and the process of controlling the sending of media streams of various media types in multimedia communication specifically includes the following steps:

Step 501: The user terminal in multimedia communication sends a media sending request carrying media type information to the media sending right management server.

Here, the user terminal in multimedia communication can send a request to multiple media through one media. The sending application for one media type is sent to the media sending right management server, or multiple media sending requests can be sent to the media sending right management server respectively through multiple media sending requests. Correspondingly, in this step, each media sending request received by the media sending right management server may carry one type of media type information or may carry multiple media type information.

Step 502: The media sending right management server inserts the received media sending request carrying media type information into its own queue.

Here, when the media sending right management server receives a media sending request carrying media type information, the media sending right management server may further send the permission sequence of the media type carried in the media sending request to the person who sent the media sending request according to the scheduling policy. user terminal, thereby notifying the user terminal of the order in which it sends media streams of different media types in the subsequent process.

In this step, the media sending right management server can insert the received media sending request into the queue in a variety of ways, including:

1. The media sending right management server inserts the received media sending requests carrying media type information into the queue in sequence according to the order of reception.

2. The media sending right management server inserts the received media sending request carrying the media type information into the queue according to the media type information carried in the media sending request.

3. Set a position for the designated user terminal in the queue in advance. In this step, the media transmission right management server first obtains the user terminal information that sent the media transmission request, and determines the user terminal based on the obtained user terminal information. After the user terminal making the media sending request is a designated user terminal, the media sending request carrying the media type information is inserted into the queue at a position set for the designated user terminal.

4. When a media sending request received by the media sending right management server carries multiple media type information, the media sending right management server splits the media sending request according to the number of media types carried in the media sending request. Divided into categories to carry each type of media separately type information, and then insert the split multiple media sending requests carrying information of each media type into the queue in the order of the set media type.

The set media type sequence is directly set by the media transmission rights management server, or is set by the media transmission rights management server according to the instructions of specific parameters in the application sent by the user terminal.

For example, the media transmission right management server receives a message carrying three media types, such as a media transmission request for voice, image and text type information. That is to say, the user terminal simultaneously requires the media transmission rights of the three media types, then The media transmission right management server splits the media transmission request carrying three media type information into three media transmission requests carrying voice, image and text type information respectively, and then follows the set media type order, for example, voice in sequence , images and text, first insert the split media sending request carrying voice type information into its own queue, then insert the split media sending request carrying image type information into its own queue, and finally Insert the split media sending request carrying text type information into the queue in itself. The set media type sequence may be directly set by the media transmission right management server, or may be set by the media transmission right management server according to specific parameters in the application message sent by the user terminal. For example, the user terminal The media sending request carrying the three media type information carries a specific parameter indicating that the order of the three media types carried in the media sending request is voice, image, text, etc.

5. When a media sending request received by the media sending right management server carries multiple media type information, the media sending right management server may directly insert the media sending request carrying multiple media type information without splitting it. to the queue.

6. The media sending right management server inserts the received media sending request carrying media type information into a designated queue of itself.

7. The media sending right management server sends the received media carrying media type information. The request is inserted into a different queue of itself.

It should be noted that the method of inserting the media sending request carrying the media type information into the queue in this step is not limited to the above seven methods, and may also include other insertion methods. Moreover, the above 7 methods can be combined, and the better combination methods can be as follows:

A. Combination of method 1 and method 6, specifically, the media sending right management server inserts the received media sending requests carrying media type information into a designated queue in itself according to the order of reception.

B. Combination of method 2 and method 7. Specifically, the present invention sets corresponding media types for different queues in advance. In this way, the media sending right management server will receive the media type carried in the media sending request according to the media type information carried in the media sending request. Media send requests for messages are inserted into the queue corresponding to the type of media being carried.

For example, the media sending right management server receives a media sending request carrying image type information, a media sending request carrying voice type information, and a media sending request carrying text type information, then in this step, the media sending right management server Insert the received media sending request carrying image type information into the queue corresponding to the image type in itself, insert the media sending request carrying voice type information into the queue corresponding to the voice type in itself, and insert text in it into the queue corresponding to the voice type. A media send request of type information is inserted into its own queue corresponding to the text type.

C. Combination of Mode 2, Mode 3 and Mode 7. Specifically, the present invention sets corresponding media types for different queues in advance; and sets the same position for the designated user terminal in the queue corresponding to each media type; media The sending right management server inserts the media sending request carrying the media type information into the position set for the designated user terminal in the queue corresponding to the media type carried in the media sending request.

Wherein, setting the same location for the specified user terminal can be done by corresponding to each This is achieved by reserving placeholders in the queue of each media type for specified user terminals. In this way, in this step, when the media sending right management server receives a media sending request carrying media type information from a user terminal, the media sending right management server first determines whether it is reserved for the user terminal in its own queue. There is a placeholder. If it is not reserved, the media sending request will be directly inserted into the queue corresponding to the media type according to the media type. If it is reserved, the media sending request will be directly inserted into the queue corresponding to the media type. The placeholder reserved in the queue for the media type being carried is not the end of the queue. Referring to Figure 6, for example, the present invention reserves a placeholder at the first position in the queue corresponding to each media type for the user terminal 4 in multimedia communication, so that each media transmission request of the user terminal 4 can be prioritized and responded to. In this way, when the media sending right management server receives a media sending request carrying media type information from other user terminals for the first time, since there is a placeholder reserved at the first position, the media The sending right management server does not insert the media sending request carrying the media type information sent by the other user terminal into the first position in the corresponding queue, but inserts it into the next position in the queue. When the media transmission right management server receives two media transmission requests carrying voice and image media type information respectively from the user terminal 4, it directly inserts the media transmission request carrying voice type I information into the queue corresponding to the voice type. At the first position, directly insert the media sending request carrying the image type information into the first position in the queue corresponding to the image type.

Wherein, setting the same position for the designated user terminal may be: the media sending right management server locates the position in the queue corresponding to the carried reference media type according to the media sending request carrying the reference media type information sent by the designated user terminal. Position determines the position set for the specified user terminal in the queue corresponding to other media types. The reference media type is specified by the media sending right management server according to specific parameters carried in the application message sent by the designated user terminal, or the reference media type is directly specified by the media sending right management server. When the reference media type is directly designated by the media transmission rights management server, the process of implementing the direct designation may be: The media transmission rights management server converts a The media type is set to the reference media type.

When the reference media type is directly designated by the media transmission rights management server, the process of implementing the direct designation may also be: when the media transmission rights management server receives a message carrying multiple media type information sent by the designated user terminal. After a media sending request, the media sending right management server splits a media sending request carrying multiple media type information sent by the designated user terminal into multiple media sending requests carrying information of each media type respectively, and Insert the split multiple media sending requests carrying information of each media type into queues corresponding to the carried media types; the reference media type is obtained by the media sending right management server. The media sending request shall be the media sending request with the largest position in the queue in which it is located, and the media type carried in the obtained media sending request shall be designated as the reference media type. For example, a designated user terminal, recorded as user terminal 1, sends a media sending request carrying three media type information: voice, image and text. The media sending right management server splits it into a media sending request carrying voice type information, When the media sending request carrying image type information and the media sending request carrying text type information are sequentially inserted into the queues of the corresponding types respectively, if the media sending request carrying voice type information is inserted into the queue of the corresponding type, if the media sending request carrying voice type information is The maximum position in the queue is position 5, and the positions of the two media sending requests carrying image and text type information respectively are 2 and 3 in the queue, then the voice type can be set to the above reference Media type, that is to say, the media sending right management server inserts the media sending request carrying image type information and the media sending request carrying text type information into the 5th position in the queue corresponding to the image and text type respectively, leaving them empty. Positions 2, 3, and 4 corresponding to the image type queue, and vacating positions 3 and 4 corresponding to the text type queue. It should also be noted that the present invention can classify various media types in advance, and each classified media type corresponds to a queue, instead of each media type corresponding to a queue. In this step, , the media sending right management server determines the category to which the media type belongs based on the media type information carried in the media sending request, and inserts the media sending request into its own queue corresponding to the classified media type. For example, the media transmission right management server receives three media transmission requests carrying voice, image and text type information respectively, and pre-classifies the voice type into one category, and divides the image and text types into one category, then in this step , the media sending right management server inserts the media sending request carrying voice into a queue corresponding to the voice class, and inserts two media sending requests carrying images and text respectively into the queue corresponding to the image and text classes in accordance with the preset insertion order. in a queue.

Step 503: When it is necessary to issue a media sending permission, that is, to grant media sending rights to the user terminal, the media sending right management server schedules media sending requests carrying media type information from its own queue according to the preset scheduling policy.

Here, the specific way in which the media transmission right management server schedules from its own queue according to the preset scheduling policy can be:

a. The media sending right management server schedules one or more media sending requests carrying media type information at a time from the queue into which the media sending requests are inserted.

b. The media sending right management server schedules media sending requests carrying media type information from the queue in sequence according to the order in which each media sending request is inserted into the queue.

c. The media sending right management server schedules each media sending request by polling the media sending requests of each media type in the queue.

Here, if in step 502, the media sending right management server inserts the media sending request carrying the media type information into the queue corresponding to the carried media type according to the media type information carried in the media sending request, then in this step , when using mode c to perform scheduling, the media sending right management server uses polling corresponding to each media type queue. Method to schedule each media to send requests.

d. Set the priority of each media type in advance, and the media sending right management server schedules each media sending request in the queue in sequence according to the priority order of the media types carried in the media sending request.

Here, the media sending right management server can set multiple specified media types to the same priority in advance; thus, in this step, the media sending right management server can schedule different media sending requests carrying the same priority media type at the same time. The request carries different media of the same priority media type.

And, if in step 502, the media sending right management server inserts the media sending request carrying the media type information into the queue corresponding to the carried media type according to the media type information carried in the media sending request, then in this step When scheduling is performed in mode d, the media sending right management server first schedules the media sending request carrying media type information in the highest priority queue, and then schedules the media sending request carrying media type information in the next highest priority queue. Until the media sending request carrying media type information in the lowest priority queue is scheduled.

It should be noted that, 'In this step, when performing scheduling in mode d, the user terminal in multimedia communication can send an application message to re-specify the priority of various media types to the media transmission right management server. Media transmission right management The server modifies the priority of each media type according to the priority of various media types specified in the application message sent by the user terminal; in this way, when subsequent scheduling is performed, the priority order of the media types carried in the media sending request is modified. According to the modified priority order, the media sending right management server schedules each media sending request carrying media type information according to the modified priority order.

It should also be noted that in this step, when scheduling is performed in mode d, when scheduling a media sending request carrying a lower priority media type, if the media sending right management server receives information carrying a higher priority media type, media sending request; media sending right management After completing the currently scheduled media sending request carrying lower priority media type, the management server immediately schedules the received media sending request carrying higher priority media type information, or the media sending right management server interrupts the currently scheduled media sending request. For media sending requests carrying lower priority media types, the media sending requests carrying higher priority media type information are immediately scheduled.

e. The media sending right management server simultaneously schedules different media sending requests carrying different media type information from the queue in one scheduling.

Here, if in step 502, the media sending right management server inserts the media sending request carrying the media type information into the queue corresponding to the carried media type according to the media type information carried in the media sending request, then in this step When scheduling is performed in mode e, in one scheduling, the media sending right management server schedules one or more media sending requests carrying media type information from different queues corresponding to different media types.

Moreover, the present invention can also pre-set conflicting media types. In this step, when performing scheduling in mode e, the media sending right management server determines whether the different media types carried in the different media sending requests currently scheduled are conflict with each other, if so, continue to perform scheduling according to other set scheduling methods, otherwise perform subsequent step 504. The preset conflicting media types may be directly designated by the media transmission right management server based on the conflicting media type information carried in the application message sent by the user terminal. For example, the voice media type and the video media type including voice components can be set as conflicting media types.

It should be noted that the scheduling method described in this step is not limited to the above-mentioned a to e methods, and may also include other insertion methods. Moreover, the above-mentioned methods a to e can be combined. For example, method a is combined with method b. That is to say, the media sending right management server schedules one or more media sending requests from the queue according to the order in which the media sending requests are inserted into the queue. A media send request carrying media type information.

It should also be noted that in step 501, when the media sending request sent by the user terminal in multimedia communication to the media sending right management server carries multiple media type information, the user terminal may further include in the media sending request Carrying parameters for applying for simultaneous authorization of multiple media types, in this step, when it is necessary to issue a media transmission permission, if the media transmission right management server schedules the media transmission request sent from the user terminal, then according to Parameters for applying for simultaneous authorization of multiple media types determine whether each media type applied for by the user terminal can currently be scheduled simultaneously. If it cannot be scheduled at the same time, the media transmission right management server will not schedule any media type that carries the user terminal application. Media sending request for media type information, that is, the media sending right of any media type applied for by the user terminal is not granted, and other media sending requests are scheduled; if possible, each media sending request carrying the user terminal application is scheduled at the same time. Media send request for media type information. For example, in step 501, user terminal 1 sends a media sending request carrying information about three media types: voice, image, and text, and the media sending request carries parameters for applying for simultaneous authorization of the three media types. In this way, In this step 503, when the media transmission right management server dispatches the media transmission request carrying the three media type information of voice, image and text from the user terminal 1 in the queue, or performs split processing according to step 502 and then dispatches it to When user terminal 1 in the queue sends a media transmission request carrying any media type information such as voice, image and text, it will be judged based on the parameters for simultaneous authorization of multiple media types to determine whether the three types applied for by user terminal 1 can be scheduled at the same time. media type. If it is not possible, the media transmission right management server will not schedule a media transmission request carrying any media type information applied for by the user terminal 1, and schedule other media transmission requests according to the scheduling policy; if it is possible, it will also schedule the media transmission request carrying The user terminal 1 applies for media sending requests for the three media type information, so that the media sending permission carrying the three media type information can be issued to the user terminal 1 at the same time, that is, the user terminal 1 is allowed to send the media of the three media types at the same time. flow. Among them, media distribution rights management The management server may determine whether each media type applied for by the user terminal can be scheduled simultaneously by determining whether the sending rights of each media type applied for by the user terminal are currently released.

Step 504: The media transmission right management server issues a media transmission permission carrying the media type information to the corresponding user terminal according to the media type information carried in the scheduled media transmission request.

Here, the corresponding user terminal refers to the user terminal that sends the currently scheduled media transmission request.

It should be noted that if in step 501, a media sending request received by the media sending right management server carries multiple media type information, and in step 502, the media sending right management server does not split it, and directly When the media sending request carrying multiple media type information is inserted into the queue as a media sending request, and the currently scheduled media sending request is a media sending request carrying multiple media type information, in this step 504, The media transmission right management server can grant the transmission rights of multiple media types to the user terminal corresponding to the currently scheduled media transmission request through a media transmission permission message carrying multiple media type information, or through multiple media transmission permission messages carrying each media type. The media transmission permission message of the type information grants the transmission rights of the multiple media types to the user terminal corresponding to the currently scheduled media transmission request.

Step 505: The user terminal that receives the media sending permission sends a media stream of the corresponding type according to the media type information carried in the media sending permission.

Here, for example, if the media type information carried in the media sending permission is text type, then in this step, the user terminal that receives the media sending permission can send its own text type media stream.

In the embodiment of the method of the present invention shown in Figure 5, the media sending right management server completes the process of inserting the media sending request sent from the user terminal into the queue and scheduling it from the queue. Procedure. In other embodiments of the method of the present invention, this process can also be completed by other devices in the network.

In the embodiment of the present invention, the application sent by the user terminal to the media transmission rights management server may be a media data control protocol (MBCP) message, a binary transmission rights control protocol (BFCP) message, or a session initiation protocol (SIP) message.

In short, the above descriptions are only preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
