具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
在本实施例中提供了一种会议呼叫的方法，图2是根据本发明实施例的一种会议呼叫方法的流程图，如图2所示，本实施例的执行主体为SIP服务器，该流程包括如下步骤：
步骤S202，SIP服务器接收呼叫终端发送的会议传输消息。
其中，该会议传输消息包括会议信息和待加入该会议的外部终端的标识信息，该标识信息可以是该外部终端的名称或编号等信息。
步骤S204，该SIP服务器将该会议信息和该外部终端的标识信息发送至MCU。
步骤S206，在该MCU根据该会议信息和该标识信息建立会议后，该SIP服务器通过该MCU呼叫该呼叫终端和该标识信息标示的该外部终端加入该会议。
通过上述步骤，呼叫终端直接通过SIP服务器与MCU完成会议的建立，避免了通过会议管理员建立会议，从而解决了无法灵活完成会议建立的问题，另外，由于不需要在单独设置会议管理员，从而节省了人力成本。
在本实施例一种可能的实现方式中，该会议传输消息包括第一INVITE消息；该SIP服务器接收该呼叫终端发送的该第一INVITE消息，这样，通过INVITE消息携带会议信息和标识信息，并与MCU交互建立会议从而简化了会议建立的过程。
示例地，在INVITE消息中，可以将该INVITE消息的格式中的字段Content-Type赋值为multipart/mixed；boundary＝"boundary1"
即由--boundary1把Content分为两部分，一部分是application/sdp，用来传SDP(Session Description Protocol，会话描述协议)信息，一部分是application/resource-lists+xml，用来传主叫呼集相关信息(即INVITE消息携带的会议信息和标识信息)。
如：
INVITE tel:xxx SIP/2.0

--boundary1—
其中，“NO2@domian”即为外部终端的标识信息。
需要说明的是，上述INVITE消息的格式以及格式中的字段信息只是举例说明，本发明对此不作限定。
可选地，上述步骤S206可以包括：在该会议传输消息包括第一INVITE消息时，该SIP服务器将该第一INVITE消息发送至该MCU；该SIP服务器接收该MCU根据该第一INVITE 消息发送的200OK消息，并将该200OK消息发送至该呼叫终端，其中，该200OK消息设置为呼叫该呼叫终端加入该会议；该SIP服务器接收该MCU发送的第二INVITE消息；该SIP服务器将该第二INVITE消息发送至该外部终端，其中，该第二INVITE消息设置为呼叫该外部终端加入该会议。在本实施例中，MCU根据第一INVITE消息直接将呼叫终端加入会议，不需要重新向呼叫终端发起邀请，从而简化了会议建立的流程。
可选地，上述步骤S206还可以包括：在该会议传输消息包括第一INVITE消息时，该SIP服务器将该第一INVITE消息发送至该MCU；该SIP服务器接收该MCU根据该第一INVITE消息发送的呼叫挂断消息；该SIP服务器将该呼叫挂断消息发送至该呼叫终端，其中，该呼叫挂断消息设置为指示挂断该呼叫终端；该SIP服务器在接收到该MCU发送的第三INVITE消息后，向该呼叫终端发送该第三INVITE消息，其中，该第三INVITE消息设置为呼叫该呼叫终端加入该会议；该SIP服务器在接收到该MCU发送的第四INVITE消息后，向该外部终端发送该第四INVITE消息，其中，该第四INVITE消息设置为呼叫该外部终端加入该会议。在本实施例中，MCU需要挂断呼叫终端的呼叫并重新向呼叫终端发起INVITE请求，从而将呼叫终端加入会议。
可选地，该第一INVITE消息还包括：会议建立时间；上述步骤S206包括：在达到该预设时间后，该SIP服务器接收该MCU发送的第三INVITE消息，并向该呼叫终端发送该第三INVITE消息；上述SIP服务器向该外部终端发送第四INVITE消息包括：在达到该预设时间后，该SIP服务器接收该MCU发送的第四INVITE消息，并向该呼叫终端发送该第四INVITE消息。
其中，若第一INVITE消息还包括会议建立时间，则MCU接收该第一INVITE消息，并通过SIP服务器挂断呼叫终端，并在达到该会议建立时间后，呼叫该呼叫终端和外部终端，这样，能够根据会议时间灵活的创建会议并呼叫待参加会议的终端(包括呼叫终端和外部终端)加入会议。
在本实施例另一种可能的实现方式中，该会议传输消息还包括INFO消息；该SIP服务器接收该呼叫终端发送的该INFO消息；上述步骤S106包括：
该SIP服务器接收该MCU发送的第五INVITE消息，并将该第五INVITE消息发送至该呼叫终端，其中，该第五INVITE消息设置为呼叫该呼叫终端加入该会议；
该SIP服务器接收该MCU发送的第六INVITE消息，并将该第六INVITE消息发送至该外部终端，其中，该第六INVITE消息设置为呼叫该外部终端加入该会议。
综上所述，如图3所示，图3为本实施例提供的一种会议呼叫的流程示意图，本实施例的流程包括如下处理步骤如下：
步骤s21：终端1(相当于呼叫终端)在INVITE中携带要召集会议的信息，如会议名称以及要一同加入会议的其他终端的号码等，发给SIP服务器；步骤s22：SIP服务器解析此次召集会议的信息，并发给MCU；步骤s23：MCU按照要召集会议的信息召开会议并呼叫终端 2(相当于外部终端)上会；步骤s24：MCU回复SIP服务器，告知会议已召开；步骤s25：SIP服务器转发终端1呼MCU的INVITE呼通MCU；步骤s26：终端成功上会，进行音视频交流。
如图4所示，图4为本实施例提供的一种会议呼叫的信令交互示意图，本实施例的流程包括如下处理步骤如下：
第一步：终端1(相当于呼叫终端)按照本发明方式，在INVITE消息中携带要召集会议的信息，如会议名称以及要一同加入会议的其他终端的号码等，发给SIP服务器；
第二步：SIP服务器解析此次召集会议的信息，并发给MCU；
第三步：MCU按照要召集会议的信息召开会议；
第四步：MCU回复SIP服务器，告知会议已召开；
第五步：SIP服务器转发终端1呼MCU的INVITE消息呼通MCU；
第六步：MCU向SIP服务器发出INVITE消息，呼叫终端2(相当于外部终端)上会。
需要说明的是，上述各步骤之间的执行顺序并不限定标示的步骤顺序，本实施例并不受所描述的动作顺序的限制，因为依据本发明，某些步骤可以采用其他顺序或者同时进行，例如对呼叫终端的呼叫和对外部终端的呼叫并不限定先呼叫呼叫终端再呼叫外部终端，也不限定先呼叫外部终端再呼叫呼叫终端，本实施例对呼叫终端和外部终端的呼叫顺序并不作限定，也可以同时进行呼叫。
这样，呼叫终端直接通过SIP服务器与MCU完成会议的建立，避免了通过会议管理员建立会议，从而解决了无法灵活完成会议建立的问题，另外，由于不需要在单独设置会议管理员，从而节省了人力成本。
在本实施例中提供了一种会议呼叫的方法，图5是根据本发明实施例的一种会议呼叫方法的流程图，如图5所示，本实施例的执行主体为MCU，该流程包括如下步骤：
步骤S502、MCU接收SIP服务器发送的设置为建立会议的会议信息和待加入该会议的外部终端的标识信息。
其中，由呼叫终端通过会议传输消息将该会议信息和该标识信息发送至该SIP服务器。
步骤S504、在根据该会议信息和该外部终端的标识信息建立该会议后，该MCU通过该SIP服务器分别向该呼叫终端和该外部终端发送呼叫消息。
其中，该呼叫消息设置为通过该SIP服务器呼叫该呼叫终端和该外部终端加入该会议。
通过采用上述实施例，呼叫终端直接通过SIP服务器与MCU完成会议的建立，避免了通过会议管理员建立会议，从而解决了无法灵活完成会议建立的问题，另外，由于不需要在单 独设置会议管理员，从而节省了人力成本。
在本实施例一种可能的实现方式中，该会议传输消息包括第一邀请INVITE消息；上述步骤S504可以包括：该MCU接收该SIP服务器发送的该第一INVITE消息；该MCU根据该第一INVITE消息通过该SIP服务器向该呼叫终端发送200OK消息，其中，该200OK消息设置为呼叫该呼叫终端加入该会议；该MCU通过该SIP服务器向该外部终端发送第二INVITE消息，其中，该第二INVITE消息设置为呼叫该外部终端加入该会议。
