Embodiment
Core concept of the present invention is, after active and standby MCU switches, terminal is known by the notice that is equipped with MCU and is switched generation, rebuliding H245, H225 connects, but keep the RTP media channel, to send to being equipped with MCU to the RTP Media Stream that former main MCU sends, thereby switch to wait and switch a realization difficult problem avoiding TCP, realization is smoothly switched.
Below in conjunction with drawings and Examples, the embodiment of a kind of MCU main among the present invention is described.
At main MCU with when being equipped with the MCU operate as normal, main MCU is backing up meeting information being equipped with on the MCU in real time, and this conferencing information comprises as predetermined conference, active conference, participant terminal, rtp streaming port information etc.Wherein active and standby MCU can adopt identical IP or different IP.
Idiographic flow when masterslave switchover takes place may further comprise the steps as shown in Figure 2:
Step s201, main MCU send switching notification message to being equipped with MCU.
This step is an optional step.Concrete, be equipped with under the situation of MCU in artificial masterslave switchover or the main MCU fashion notice of having the ability that breaking down of initiating, main MCU need initiate masterslave switchover by switching notification message notice backup MCU.Need to carry following information in this switching notification message 1: main MCU address is equipped with MCU address (both can be identical).
Step s202, be equipped with MCU and send to the user terminal of each participant and switch generation message.
Concrete, be equipped with MCU when receiving the switching notification message that main MCU sends, when perhaps detecting main MCU and break down by certain mode (as the heartbeat testing mechanism), judgement need switch to this equipment main MCU.At this moment, be equipped with MCU and switch generation message, notify each user terminal to switch generation to the user terminal transmission of each participant.In addition, if the address difference of active and standby MCU is switched at this IP of MCU is fully taken place to need in the message to carry.
Step s203, user terminal are hung up message to being equipped with MCU transmission call signaling.
Concrete, user terminal receives that MCU fully sends switches to take place to disconnect after the message and is connected with H225, the H245TCP of former main MCU, and hangs up message to MCU responding call signaling fully, carries the user terminal ID in the generation message of switching that receives in this message.But still the RTP Media Stream between the port of maintenance and former media channel sends and receives.For main MCU IP address be equipped with the identical situation in MCU IP address, directly keep transmission and reception between RTP Media Stream and former MCU IP address; For main MCU address be equipped with the different situation in MCU address, rtp streaming is sent to switch the IP address that is equipped with MCU that the message appointment takes place immediately.This address change can not influence the variation of the destination interface of the rtp streaming that terminal sends, and promptly backs up port that MCU equipment is used for the rtp streaming of receiving terminal, to be used for the port of rtp streaming of receiving terminal before identical with main MCU.
In concrete realization, backup MCU can guarantee that the rtp streaming that terminal sends can correctly arrive MCU by mechanism such as transmission ARP (Address ResolutionProtocol, address resolution protocol) messages.Switching back terminal and MCU initiatively send I frame (key frame) separately makes this process more level and smooth.
Backup MCU knows that receiving after call signaling hangs up message terminal has expansion and switches ability, then after receiving the rtp streaming that terminal sends, handles immediately and sends stream after handling to terminal.
Step s204～step s207, be equipped with between MCU and the user terminal and set up the H245 passage.
Concrete, user terminal or MCU make a call, and making a call with user terminal is example:
Q.931 step s204, user terminal pass through, and message sends Setup message to being equipped with MCU.Q.931 message is based upon in the H225 connection, for carrying out the employed agreement of information interaction, mainly is responsible for the signaling process in the calling procedure, and the H245 mailing address and the port of negotiate further on this basis.
Step s205, be equipped with MCU and send Call Proceeding (call treatment) message by message Q.931 and give user terminal, comprising H245 channel address information.
Step s206, be equipped with MCU and send Alerting (warning) message to user terminal, comprising H245 channel address information by message Q.931.
Step s207, be equipped with MCU and user terminal carries out capability negotiation according to the normal flow of H245, and open media channel.The port numbers of rtp streaming before this media channel uses and switches, promptly use current with the employed port of terminal transmission rtp streaming is opened and user terminal between media channel, but do not carry out the rtp streaming opening procedure of reality.Just enter the state before switching afterwards.
If user terminal is not supported being equipped with the processing of switching generation message that MCU sends among the step s202, then in step 203, user terminal will ignore that MCU fully sends switches generation message, carry out existing normal process flow process, be shown in the step s208: detect with after being connected of main MCU disconnects, disconnect all connections of terminal therewith; Be equipped with MCU simultaneously and detect user terminal and do not send call signaling and hang up message, according to strategy this user terminal is carried out disconnection recalling again.

At main MCU with when being equipped with the MCU operate as normal, main MCU is backing up meeting information being equipped with on the MCU in real time, and this conferencing information comprises as predetermined conference, active conference, participant terminal, rtp streaming port information etc.
Be equipped with MCU and detect when main MCU breaks down, switch generation message to user terminal A and user terminal B transmission, notice is switched generation, needs to carry notified user terminal ID in this message, and this is equipped with the IP:1.0.0.2 of MCU.
Suppose that user terminal A has the ability of switching generation message that MCU sends that is equipped with of handling.Then user terminal A receives that MCU fully sends switches to take place to disconnect after the message and is connected with H225, the H245TCP of former main MCU, and hangs up message to MCU responding call signaling fully, carries the user terminal ID in the generation message of switching that receives in this message.The rtp streaming that will send to the port Port1 of 1.0.0.1 before immediately sends to the same port of the IP address 1.0.0.2 that is equipped with MCU simultaneously.Afterwards, be equipped with MCU and user terminal and consult and open media channel again, this media channel still uses former port constant, promptly be equipped with MCU use current with the employed port of terminal transmission rtp streaming is opened and user terminal A between media channel, user terminal A is still used Port 1 in MCU side fully.
Suppose that user terminal B does not have the ability of switching generation message that MCU sends that is equipped with of handling.Then detect with after being connected of main MCU disconnects, user terminal B disconnects all connections; Being equipped with MCU simultaneously detects user terminal B and does not send call signaling and hang up message, according to strategy this user terminal B is being carried out disconnection recalling, after user terminal B receives this disconnection recalling, hold consultation and set up new media channel, restart the transmission of rtp streaming with being equipped with MCU.
