步骤302：第一SMC确定第一MCU的身份，并在确定出为从MCU时，根据保存的MCU的会议号与会场终端的终端号码的对应关系，确定接入第一MCU的第一会场终端。Step 302: The first SMC determines the identity of the first MCU, and determines that the first site terminal that accesses the first MCU is determined according to the correspondence between the saved MCU conference number and the terminal number of the site terminal. .

第一SMC可以获取到第一MCU的会议号，且第一SMC内保存有主MCU的会议号与从MCU的会议号之间的对应关系，MCU的会议号与会场终端的终端号码之间的对应关系。相应的，本步骤可以为：The first SMC can obtain the conference number of the first MCU, and the first SMC stores the correspondence between the conference number of the master MCU and the conference number of the slave MCU, and between the conference number of the MCU and the terminal number of the conference terminal. Correspondence relationship. Correspondingly, this step can be:

第一SMC判断主MCU的会议号与从MCU的会议号之间的对应关系中存储的主MCU的会议号是否包括第一MCU的会议号，假设判断出的结果为不包括，便确定出第一MCU的身份为从MCU，然后根据第一MCU的会议号，从保存的MCU的会议号与会场终端的终端号码之间的对应关系中获取对应的会场终端的终端号码，确定获取的终端号码对应的第一会场终端。The first SMC determines whether the conference number of the primary MCU stored in the correspondence between the conference number of the primary MCU and the conference number from the MCU includes the conference number of the first MCU, and if the determined result is not included, the first determination is made. The identity of an MCU is the slave MCU, and then the terminal number of the corresponding conference terminal is obtained from the correspondence between the conference number of the saved MCU and the terminal number of the conference terminal according to the conference number of the first MCU, and the obtained terminal number is determined. Corresponding first venue terminal.

例如，SMC B内保存如表3所示的主MCU的会议号与从MCU的会议号之间的对应关系，以及保存有如表4所示的MCU的会议号与会场终端的终端号码之间的对应关系。在本步骤中，SMC B可以获取到MCU B的会议号为ID B，判断出如表3所示的主MCU的会议号与从MCU的会议号之间的对应关系中存储的主MCU的会议号不包括MCU B的会议号，从而判断出 MCU B的身份为从MCU，根据MCU B的会议号ID B，从如表4所示的MCU的会议号与会场终端的终端号码之间的对应关系中获取对应的会场终端3的终端号码0755001和会场终端4的终端号码0755002，其中终端号码0755001对应的会场终端3和终端号码0755002对应的会场终端4为接入MCU B的第一会场终端。For example, the SMC B stores the correspondence between the conference number of the primary MCU and the conference number from the MCU as shown in Table 3, and the conference number between the MCU and the terminal number of the conference terminal stored in Table 4 Correspondence relationship. In this step, the SMC B can obtain the conference number of the MCU B as ID B, and determine the conference of the primary MCU stored in the correspondence between the conference number of the primary MCU and the conference number from the MCU as shown in Table 3. The number does not include the conference number of the MCU B, so that it is judged The identity of the MCU B is the slave MCU, and the terminal number of the corresponding conference terminal 3 is acquired from the correspondence between the conference number of the MCU and the terminal number of the conference terminal as shown in Table 4 according to the conference number ID B of the MCU B. The terminal number 4 is 0755002, and the site terminal 4 corresponding to the site terminal 3 and the terminal number 0755002 corresponding to the terminal number 0755001 is the first site terminal that accesses the MCU B.

步骤303：第一SMC为第一会场终端分配第二MCU。Step 303: The first SMC allocates a second MCU to the first site terminal.

The first site terminal allocates the corresponding second MCU; if it is determined that the MCU with the idle resource is not included, the conference recovery fails and the operation ends.

例如，假设，SMC B所在域除了包括MCU B外，还包括MCU D和MCU E，且MCU D和MCU E都具有空闲资源。这样SMC B从MCU D和MCU E中分别为会场终端3和会场终端4分配第二MCU，假设分配的第二MCU都是MCU D。For example, it is assumed that the domain in which the SMC B is located includes, in addition to the MCU B, MCU D and MCU E, and both MCU D and MCU E have idle resources. In this way, the SMC B allocates the second MCU from the MCU D and the MCU E to the site terminal 3 and the site terminal 4, respectively, assuming that the allocated second MCUs are all MCU Ds.
