Embodiments provide a kind of method recovering meeting, and the conferencing resource that this meeting is used includes one SMC, a MCU and access multiple meeting-place terminal of this MCU, this MCU is called a MCU for convenience of description.This SMC is to first MCU detects, when detecting a MCU exception, for being somebody's turn to do from other MCU in addition to a MCU that territory, place includes Multiple meeting-place terminal distribution the 2nd MCU, the 2nd MCU has idling-resource, to the 2nd MCU send in the plurality of meeting-place terminal every The termination number of individual meeting-place terminal；2nd MCU, according to the termination number of each meeting-place terminal, sets up and each meeting-place terminal respectively Between meeting connect, with realize recover this meeting.

Embodiments providing a kind of method recovering meeting, the conferencing resource that this meeting is used includes multiple SMC, multiple MCU and multiple meeting-place terminal.The method is applied to when occurring abnormal for certain held a meeting from MCU recover This meeting.Seeing Fig. 3-1, the method includes:

Step 301 a: SMC detects, when detecting a MCU for the MCU held a meeting in its territory, place Step 302 is performed time abnormal.

Oneth SMC is the arbitrary SMC for holding this meeting, for being used in a territory, SMC place holding this meeting Each MCU, a SMC, by detecting the heartbeat message of transmission between itself and each MCU, detect abnormal MCU.

Step 302 a: SMC determines the identity of a MCU, and determining as during from MCU, according to the MCU's preserved Meeting number and the corresponding relation of the termination number of meeting-place terminal, determine the first meeting-place terminal accessing a MCU.

Oneth SMC preserve in can getting the meeting number of a MCU, and a SMC meeting number of main MCU with from Corresponding relation between the meeting number of MCU, the corresponding relation between meeting number and the termination number of meeting-place terminal of MCU.Accordingly , this step can be:

Oneth SMC judges the main MCU of storage the meeting number of main MCU and the corresponding relation between the meeting number of MCU Whether meeting number includes the meeting number of a MCU, it is assumed that the result judged, for not include, just determines the identity of a MCU For from MCU, then according to the meeting number of a MCU, between meeting number and the termination number of meeting-place terminal of the MCU preserved Corresponding relation obtains the termination number of the meeting-place terminal of correspondence, determines the first meeting-place terminal that the termination number of acquisition is corresponding.

Such as, the meeting number pass corresponding with between the meeting number of MCU of main MCU as shown in table 3 is preserved in SMC B System, and preserve the corresponding relation between the meeting number of MCU as shown in table 4 and the termination number of meeting-place terminal.In this step In Zhou, SMC B can get the meeting number of MCU B for ID B, it is judged that the meeting number of main MCU as shown in table 3 with from MCU Meeting number between corresponding relation in the meeting number of main MCU of storage do not include the meeting number of MCU B, thus judge MCU The identity of B is from MCU, according to the meeting ID B of MCU B, from the terminal of the meeting number of MCU as shown in table 4 with meeting-place terminal Corresponding relation between number obtains termination number 0755001 and the termination number of meeting-place terminal 4 of the meeting-place terminal 3 of correspondence 0755002, wherein the meeting-place terminal 3 of termination number 0755001 correspondence and the meeting-place terminal 4 of termination number 0755002 correspondence are Access the first meeting-place terminal of MCU B.

Step 303 a: SMC is the first meeting-place terminal distribution the 2nd MCU.
