However, when the multiparty audio-video conference is performed, if the transmission quality of other terminals has larger time delay and packet loss, the transmission quality of the VIP user terminal is ensured independently, the participating conference quality cannot be ensured, and the conference quality of the VIP user terminal is affected because the multiparty audio-video conference still has data loss.
Based on the above, the technical scheme of the invention ensures the interaction quality of the VIP user terminal and other terminals in the audio and video conference by enhancing the transmission quality of each terminal in the audio and video conference where the VIP user terminal is located, thereby ensuring the participation quality of the VIP user terminal.
In accordance with an embodiment of the present invention, there is provided an enhanced embodiment of multimedia conference quality, it being noted that the steps shown in the flowcharts of the figures may be performed in a computer system, such as a set of computer executable instructions, and, although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be performed in an order other than that shown or described herein.
In this embodiment, a method for enhancing the quality of a multimedia conference is provided, which may be used for electronic devices, such as a mobile phone, a tablet computer, a corresponding controller of a computer, etc., fig. 2 is a flowchart of a method for enhancing the quality of a multimedia conference according to an embodiment of the present invention, as shown in fig. 2, where the flowchart includes the following steps:
s11, acquiring target multimedia conference information reported by each switch, wherein the target multimedia conference information comprises conference identifications corresponding to the target multimedia conferences and terminal information of terminals associated with the conference identifications.
The target multimedia conference is an audio-video conference in which a plurality of terminals participate, and after the target multimedia conference information is established for the multimedia conference, the target multimedia conference corresponds to the related information. Specifically, the target multimedia conference state information may include a conference identifier ID and terminal information of a terminal associated with the conference identifier, where the terminal information is attribute information for characterizing uniqueness of a participant terminal, and specifically, the terminal information may be a MAC address of the terminal, and of course, may also be other information. The establishment time, the conference name, the conference authority and the like of the target multimedia conference can also be determined based on the conference identification ID.
Specifically, taking the topology structure shown in fig. 1 as an example, when a certain terminal initiates a multimedia conference and other terminals join the multimedia conference, the switch serving as an access device and the switch serving as a core device can monitor the establishment of a target multimedia conference in real time, report the target multimedia conference information to the controller, and accordingly, the controller can acquire the target multimedia conference information reported by each switch and store the target multimedia conference information.
S12, determining the terminal with the target identifier in the terminal information as a target terminal.
The target identifier is identifying information of the target terminal and distinguishing the target terminal from other terminals, and the data message associated with the target terminal can be scheduled preferentially. Specifically, the target identifier may be a VIP identifier, and the controller may identify whether terminal information corresponding to each terminal carries the VIP identifier, and determine the terminal carrying the VIP identifier as the target terminal.
And S13, when a target terminal exists in the terminals participating in the target multimedia conference, determining a target switch associated with the target terminal, and acquiring a priority forwarding strategy.
The priority forwarding strategy is used for scheduling the data message associated with the target terminal preferentially, and when the target terminal exists in the terminals participating in the target multimedia conference, the controller can determine the target switch associated with the target terminal according to the target multimedia conference information, and simultaneously acquire the priority forwarding strategy corresponding to the current target terminal.
Alternatively, the controller may be locally configured with a device list corresponding to the target terminal, the controller determines each terminal participating in the target multimedia conference according to the terminal information included in the target multimedia conference information, and determines whether there is a target terminal among the terminals participating in the target multimedia conference by querying the local device list. When it is determined that a target terminal exists in terminals participating in the target multimedia conference, a corresponding priority forwarding policy is acquired, and it is determined that a target switch is associated with the corresponding priority forwarding policy.
And S14, issuing a priority forwarding strategy to the target switch so that the target switch controls the data message to carry out priority transmission scheduling in a communication link where the target terminal is located according to the priority forwarding strategy, wherein the communication link is a link where the target terminal communicates with other terminals in the target multimedia conference in which the target terminal participates, and the data message carries a priority identifier corresponding to the priority forwarding strategy.
The data message is a message sent by the target terminal or a message to be forwarded to other terminals participating in the target multimedia conference after being mixed by the MCU, and the data message carries a priority identifier corresponding to a priority forwarding strategy. The communication link is a link through which the target terminal performs data communication with other terminals. After determining the target switch associated with the target terminal, the controller may issue a priority forwarding policy to the target switch, so that the target switch may control the data packet to be preferentially transmitted and preferentially scheduled in the communication link where the target terminal is located according to the priority forwarding policy.
According to the method for enhancing the quality of the multimedia conference, the controller monitors the target multimedia conference information reported by the exchange side in real time, when the target terminal exists in the terminals of the target multimedia conference, a priority forwarding strategy is issued to the target exchange associated with the target terminal in time, so that the target exchange can control the data message to be preferentially scheduled in a communication link where the target terminal is located according to the priority forwarding strategy, the data message transmission quality between the target terminal and other terminals participating in the target multimedia conference is ensured, the quality assurance of the target terminal in the multiparty multimedia conference is enhanced, and the Internet surfing participation experience of the target terminal is improved.
In this embodiment, a method for enhancing the quality of a multimedia conference is provided, which may be used for electronic devices, such as a mobile phone, a tablet computer, a corresponding controller of a computer, etc., fig. 3 is a flowchart for enhancing the quality of a multimedia conference according to an embodiment of the present invention, and as shown in fig. 3, the flowchart includes the following steps:
s21, acquiring target multimedia conference information reported by each switch, wherein the target multimedia conference information comprises conference identifications corresponding to the target multimedia conferences and terminal information of terminals associated with the conference identifications. The detailed description is referred to the related description of the step S11 corresponding to the above embodiment, and will not be repeated here.
S22, determining the terminal with the target identifier in the terminal information as a target terminal.
And determining whether a target terminal exists in the terminals or not based on the terminal information, wherein the target terminal is a terminal with a terminal grade greater than a preset grade. When there is a target terminal among the terminals, steps S23 to S25 are performed; when there is no target terminal among the terminals, step S26 and step S27 are performed.
S23, when the target terminal exists in the terminals participating in the target multimedia conference, acquiring the priority level corresponding to the target terminal.
The priority level corresponding to the target terminal is the priority level of the target terminal, and the priority level can be determined based on the terminal level of the target terminal, that is, the higher the terminal level is, the higher the priority level is. For example, the terminal level of the target terminal is VIP1 level, and the priority level thereof is QOS1; if the terminal level of the target terminal is VIP2 level, the priority level is QOS2, and QOS2 is greater than QOS1.
And S24, associating the priority level with the target multimedia conference.
And associating the priority level with the multimedia conference so that each terminal participating in the target multimedia conference can schedule the priority transmission of the data message according to the priority level. For example, when the controller determines that there is a target terminal in the terminals participating in the target multimedia conference, and the target identifier of the target terminal is VIP1 and the priority level is QOS1, the controller may identify the priority level of the target multimedia conference as QOS1, and simultaneously assign a unique VIP tag to the target multimedia conference to identify the target multimedia conference as a VIP conference, where the VIP tag may be any static tag from 0 to 1024.
S25, when a target terminal exists in the terminals participating in the target multimedia conference, determining a target switch associated with the target terminal, and acquiring a priority forwarding strategy. The detailed description is referred to the related description of the step S13 corresponding to the above embodiment, and will not be repeated here.
S26, a priority forwarding strategy is issued to the target switch, so that the target switch controls the data message to carry out priority transmission scheduling in a communication link where the target terminal is located according to the priority forwarding strategy, wherein the communication link is a link where the target terminal communicates with other terminals in the target multimedia conference in which the target terminal participates, and the data message carries a priority identifier corresponding to the priority forwarding strategy. The detailed description is referred to the related description of the step S14 corresponding to the above embodiment, and will not be repeated here.
And S27, when the target terminal does not exist in the terminals participating in the target multimedia conference, the tunnel identification corresponding to each switch is issued, so that each switch controls the transmission scheduling of the data message according to the tunnel identification.
The tunnel identifier is used for representing a transmission channel of the switch, when a target terminal does not exist in terminals participating in the target multimedia conference, data interaction is performed between the terminals through the MCU, no priority identifier exists in a data message, the data message can only be forwarded normally between the switches, and at the moment, the controller can issue a Segment Routing (SR) label for transmitting the data message to the switches, and the SR label is the tunnel identifier corresponding to the switch. And the switch encapsulates the SR label into the data message, and controls the data message to transmit and schedule among the switches according to the SR label.
According to the method for enhancing the quality of the multimedia conference, when the target terminal does not exist in the terminals participating in the target multimedia conference, the tunnel identification corresponding to the switch is issued, so that the switch can control data messages to be transmitted among the switches according to the tunnel identification, namely the data messages are forwarded normally, and therefore normal data transmission of each terminal in the multimedia conference is ensured. When a target terminal exists in terminals participating in the multimedia conference, the controller associates the priority level with the target multimedia conference by acquiring the priority level of the target terminal, so that each terminal participating in the target multimedia conference can enjoy the priority level, and the data transmission quality among the terminals participating in the target multimedia conference is ensured.

In this embodiment, a method for enhancing the quality of a multimedia conference is provided, which may be used for an electronic device, such as a switch corresponding to a mobile phone, a tablet computer, a computer, etc., and fig. 5 is a flowchart for enhancing the quality of a multimedia conference according to an embodiment of the present invention, and as shown in fig. 5, the flowchart includes the following steps:
s41, acquiring the establishment state of the target multimedia conference. The detailed description is referred to the related description of the step S31 corresponding to the above embodiment, and will not be repeated here.
And S42, when the target multimedia conference is established, acquiring terminal information corresponding to each terminal participating in the target multimedia conference and conference identification corresponding to the target multimedia conference. The detailed description is referred to the related description of the step S32 corresponding to the above embodiment, and will not be repeated here.
And S43, generating target multimedia conference information based on the conference identification and the terminal information, and sending the target multimedia conference information to the controller so that the controller can issue a priority forwarding strategy according to the terminal information. For detailed description, reference is made to the related description of the step S33 corresponding to the above embodiment, which is not repeated here.
S44, receiving a priority forwarding strategy issued by the controller, and controlling the data message to transmit and dispatch in a communication link where the target terminal is located based on the priority forwarding strategy, wherein the target terminal is a terminal with a target identifier in terminal information, and the data message carries a priority identifier corresponding to the priority forwarding strategy.
Specifically, the step S44 may include the steps of:
s441, obtaining the data message to be scheduled.
The data message to be scheduled is a message sent by a terminal in the target multimedia conference or a message which is mixed by the MCU and is forwarded to each terminal participating in the target multimedia conference. The switch can acquire the data messages reported by all terminals in the target multimedia conference and control the data messages to carry out data interaction through the switch.
S442, analyzing the matching item information corresponding to the data message.
The matching item information is used for identifying the source of the data message, and comprises a message source IP, an RTP SSRC, a destination IP and a destination port. For a switch connected with a terminal, a message source IP is a terminal address, a target IP is an MCU address, an RTP SSRC is audio and video source information of a multimedia conference, and the RTP SSRC corresponds to the multimedia conference with a conference identifier; for a switch connected with the MCU, a message source IP is an MCU address, a destination IP is the address of each terminal, and RTP SSIC is audio and video source information mixed by the MCU.
S443, judging whether the matching item information hits the priority forwarding strategy.
The switch determines whether the data message corresponding to the matching item information hits the priority forwarding strategy according to the matching item information, when the matching item information hits the priority forwarding strategy, step S444 is executed, otherwise, the data message is a common message, and message scheduling is performed according to a normal forwarding flow.
And S444, carrying out priority transmission scheduling on the data message according to a priority forwarding strategy.
When the matching item information hits the priority forwarding strategy, the switch can schedule and forward the data message according to the priority level corresponding to the priority forwarding strategy. Specifically, the switch may encapsulate the SR tag in the data packet, and forward the data packet after the SR tag is encapsulated to the intermediate device (core switch), so that the intermediate device performs scheduling and forwarding of the packet according to the priority level.
Specifically, the step S444 may include:
(1) And analyzing the encapsulation information of the data message, and determining the tunnel identifier and the priority identifier carried by the data message.
When the switch forwards the data message, the switch can analyze the data message and determine the encapsulation information, the tunnel identifier and the priority identifier carried by the current data message, namely the SR label and the VIP label. As shown in fig. 6, when the switch receives the data packet, the switch can analyze the MAC address, SR tag, VIP tag, IP address, UDP information, RTP information, and audio/video data of the data packet.
(2) And determining a destination port corresponding to the data message based on the tunnel identifier.
The destination port is an output port of the data message to be forwarded by the current switch, and the switch can forward the data message to the corresponding destination port according to the SR label analyzed by the switch.
(3) And preferentially forwarding the data message to the destination port based on the priority identification.
When forwarding the data message based on the SR label, the switch can perform priority scheduling on the data message according to the analyzed VIP label, so as to determine that the data message can be forwarded normally. If the current switch is a tail node switch, the current switch can be preferentially scheduled according to the VIP label, and the message forwarding is performed according to the resolved IP address.
According to the method for enhancing the quality of the multimedia conference, the switch analyzes the data message to be scheduled, determines the corresponding matching item information of the data message, determines whether the data message to be scheduled needs to be scheduled preferentially according to whether the matching item information hits a priority forwarding strategy, and accordingly further ensures that the data message in the data link where the target terminal is located can be scheduled preferentially, data transmission quality of each terminal in the multimedia conference where the target terminal is located is enhanced, and further the reference quality of the target terminal is improved. The exchanger determines the tunnel identification and the priority identification carried by the data message by analyzing the encapsulation information of the data message; the destination port corresponding to the data message is determined based on the tunnel identifier, and the data message is forwarded to the destination port preferentially based on the priority identifier, so that the data message can be transmitted to the destination port preferentially, and meanwhile, the transmission efficiency and the transmission accuracy of the data message are both considered.
An example of a method for enhancing the quality of a multimedia conference is provided in this embodiment to explain the above method in detail. Taking the park network shown in fig. 1 as an example, leaf1, leaf2 and Leaf3 are access devices, spine is an intermediate device, leaf1, leaf2, leaf3 and Spine are switches, and they can monitor the audio and video conference establishment process based on SIP and h.225, and report audio and video conference information in the network to the controller in real time. And the Leaf1, the Leaf2 and the Leaf3 hang down the host1, the host2 and the host3 respectively, wherein the host1 is a VIP terminal, the host2 and the host3 are common terminals, audio and video software is installed on the host1, the host2 and the host3, and the registration is completed to the H.323 server.
In the initial state, host2 initiates a video conference, the conference ID is ID1, and host3 joins the conference;
the conference 1, the conference 2, the conference 3 and the Spine can monitor the establishment process of the video conference, and report conference ID, conference establishment time, terminal information, conference name, authority and other video conference information to the controller; the controller stores the video conference information, and queries a locally configured VIP terminal table according to the terminal information to determine whether a VIP terminal exists in the video conference;
The controller determines that both host2 and host3 are not VIP terminals by querying the VIP terminal table, and at this time, the controller does not trigger the issuing of the priority forwarding policy. The host2 and the host3 carry out interactive data through the MCU, data messages are normally forwarded on the switch, and the SR labels are packaged and then transmitted between the switches;
when host1 joins the video conference, leaf1, leaf2, leaf3 and Spine report the updated information of the video conference to the controller, and the controller stores the updated video conference information and analyzes the video conference information;
the controller determines host1 newly added into the video conference as the VIP terminal by inquiring the VIP terminal table, wherein the priority level is QOS1, at the moment, the controller can identify that the video conference ID1 is the VIP conference, the priority level is QOS1, unique VIP labels are allocated to the video conference, and a priority forwarding strategy is issued to Leaf1, leaf2, leaf3 and Spine, and optionally, the VIP labels can use static labels within 0-1024;
at this time, there is a priority forwarding policy on Leaf2, leaf2 is a switch connected to the terminal, the message source ip=host 1, the destination ip=mcu, RTP ssrc=host 1 (VIP conference) in the matching item, the priority level of the identification data message is QOS1, and the egress tunnel label is an SR label and a VIP label. The Leaf2 transmits the data message to the intermediate equipment Spine according to QOS1 scheduling, and the data message is an SR message carrying an SR label and a VIP label;
The intermediate equipment Spine receives the SR message, forwards the message to Leaf3 according to the SR label, and simultaneously carries out QOS1 scheduling and forwarding to the output port according to the VIP label;
leaf3 receives the SR message, flicks the SR tunnel, forwards the message to MCU, and dispatches QOS1 to the outlet port according to VIP label;
the MCU mixes the data and then forwards the data to Leaf3 again, wherein Leaf3 is a switch connected with the MCU, at the moment, the message source IP=MCU, the destination IP=other terminals (if the data are unicast addresses, multiple copies are copied and sent to each terminal respectively), and RTP SSRC=MCU (VIP conference);
and matching a priority forwarding strategy on the Leaf3, marking that the priority level of the data message is QOS1, marking that the exit tunnel label is an SR label and a VIP label, and forwarding the data message to the Spine according to the priority level schedule of QOS 1. It should be noted that, if the destination ip=host 3, at this time, leaf3 does not need to encapsulate a tunnel label, and directly forwards to host3 according to QOS1 priority scheduling;
the Spine receives the SR message, forwards the SR message to the Leaf1 according to the SR label, and dispatches and forwards the SR message to the Leaf1 according to the QOS1 of the VIP label;
and the Leaf1 receives the SR message, pops off the SR tunnel, forwards the data message to the host1, and simultaneously carries out QOS1 scheduling to the output port according to the VIP label.
By the mode, the controller realizes the full-path scheduling of the video conference participated by the VIP terminal, and all terminals in the video conference can receive video data streams according to the priority level of the VIP terminal, so that the overall quality of the conference is ensured, and the participation experience and the participation quality of the VIP terminal are improved.
