Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of multimedia services, and in particular to a service management method, MCU, MRC and MCU video conferencing system. Background Art

[0002] like Figure 1 The existing MCU (Multipoint Control Unit) video conferencing system includes: MRC (Media Router & Resource Controller), MCU and SBC (Session Border Controller) (SBC is not shown in the figure), which provides video conferencing services for users. MRC is the master controller that manages each MCU, and MCU is the actual media surface processing unit.

[0003] In a video conference, one or more MCUs will serve all users, and each MCU is accessed by multiple UEs (User Equipment, also known as terminals). The process of UE subscribing to multiple screens is as follows: UE initiates multiple screen subscription, and MRC instructs the MCU serving the UE to reserve codec and mixed screen resources. After the MCU reserves codec and mixed screen resources, it subscribes to the MCU of the required split screen, performs codec and mixed screen, and sends the video stream to the UE.

[0004] MCU consists of four parts: MR (Media Router), DEC (Decoder), ENC (Encoder) and BC (Blend Center). The internal video mixing process of MCU is that MR initiates a data routing request to the video source MCU, decodes the data while receiving it, then performs multi-screen mixing, and finally encodes it.

[0005] The existing MCU video conferencing system has the following problems:

[0006] Slow upgrade deployment: Each MCU has fixed functions (that is, the services it can provide are fixed). When customers or business demanders need to add new services, all MCUs running services in the network need to be upgraded and debugged with the MRC. The upgrade and debugging time is long, and it is difficult to adapt to the requirements of rapid launch and update of new services.

[0007] Difficulty in network element maintenance: Due to the different services added and network elements upgraded each time, the functions of various MCUs in the current network are different. This brings difficulties to the MRC in managing multiple versions of MCUs, and the MCU network management itself also needs to manage multiple versions of MCUs.

[0008] Difficulty in intercommunication between network elements: The interface parameters of the upgraded MCUs have changed, resulting in difficulty in intercommunication between MCUs and between MCUs and MRCs. Summary of the invention

[0182] Step 52: MRC-SMF reviews the services that need to be registered and returns the service registration results to MCU-SMF.

[0183] (2)MCU service release process

[0184] Please refer to Figure 6 ,The MCU service release process includes the following steps:

[0185] Step 61: MCU-SPF (i.e., SPF in MCU) sends service publishing information to MRC-SPF (i.e., SPF in MRC), where the service publishing information carries information about the service to be published;

[0186] Step 62: MRC-SPF sends a service publishing notification to MRC-SC, where the service publishing notification carries information about the service to be published.

[0187] Step 63: MRC-SC (i.e., SC in MRC) reviews the services to be released and returns the review results to MRC-SPF;

[0188] Step 64: MRC-SPF returns the audit information to MCU-SPF;

[0189] Step 65: If the review is passed, MRC-SC performs service management on the service (such as service launch and service de-launch).

[0190] In an embodiment of the present invention, the above process may be in an asynchronous manner. The so-called asynchronous manner means that there is no specified feedback time limit for the request information. For example, for the service release information of the MCU, the MRC does not need to feedback the review result within the specified time limit.

[0191] (3) MCU service discovery process

[0192] Please refer to Figure 7 ,The MCU service discovery process includes the following steps:

[0193] Step 71: MCU-SPF sends service discovery information (such as query or subscription form) to MRC-SPF;

[0194] Step 72: The MRC-SPF returns a service information notification to the MRC-SPF, where the service information notification includes the address of the SEF of the MCU of the service provider and legal authentication information.

[0195] In the embodiment of the present invention, the above process may be performed asynchronously.

[0196] (4)MCU-SF service call process

[0197] Please refer to Figure 8 ,The MCU service discovery process includes the following steps:

[0198] Step 81: MCU1-SEF sends a service call request to MCU2-SEF, where the service call request carries information about the service to be called and legal authentication information of the MCU2-SEF;

[0199] Step 82: After MCU2-SEF authenticates MCU1-SEF, it forwards / transparently transmits the service call request to MCU2-SF;

[0200] Step 83: MCU2-SF provides services to MCU1.

[0201] In the embodiment of the present invention, the above process may be performed asynchronously.

[0202] (5) Business execution process

[0203] Please refer to Fig. 9 , the business execution process includes the following steps:

[0204] Step 91: MRC-SC sends a service instruction to MCU1-SMF;

[0205] Step 92: MCU1-SMF parses the service instruction, splits the parsed service instruction into a service call plan, and sends the service call plan to MCU1-SEF;

[0206] Step 93: MCU1-SEF makes service calls to each MCU-SEF according to the service call plan.
