具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部 的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
为了方便理解，对本发明实施例中所涉及的部分术语及相关技术进行解释：
SIP是一个应用层的信令控制协议。用于创建、修改和释放一个或多个参与者的会话。这些会话可以是互联网Internet多媒体会议、网际互连协议(internet protocol，IP)电话或多媒体分发。会话的参与者可以通过组播(multicast)、网状单播(unicast)或两者的混合体进行通信。多个电子设备间通过基于SIP协议的应用程序创建会话。
如图1所示，为两个电子设备间建立基于SIP的会话的流程简图。当电子设备1想要与电子设备2建立基于SIP的会话时，电子设备1向代理服务器发送INVITE请求，该请求中包括电子设备2所代表的用户的统一资源标识符(uniform resource identifier，URI)，代理服务器接收到电子设备1发送的INVITE请求后，根据该INVITE请求中携带的URI解析出电子设备2的真实网络地址，并向电子设备2转发电子设备1发送的INVITE请求。代理服务器在转发电子设备1发送的INVITE请求的同时，还会向电子设备1发送100尝试Trying消息，以防止电子设备1重复发送INVITE请求。电子设备2在接收到代理服务器转发的INVITE请求后，在振铃提醒用户的同时，还会向代理服务器发送180振铃Ringing消息，代理服务器在接收到电子设备2发送的180Ringning消息后，将该消息转发给电子设备1。用户听到电子设备2的振铃提醒后，接通该会话，此时，电子设备2向代理服务器发送200确认OK消息，告知代理服务器电子设备2已经接通该会话。代理服务器在接收到电子设备2发送的200OK消息后，将该消息转发至电子设备1，之后电子设备1直接向电子设备2发送确认字符(Acknowledge character，ACK)消息。此时，电子设备1与电子设备2都获取 到了对象的真实网络地址，因此，双方可以脱离代理服务器直接进行通信。电子设备2接收到电子设备1发送的ACK消息后，会话建立成功，电子设备1和电子设备2间可以发送基于实时传输协议(real-time transport protocol，RTP)和(real-time transport control protocol，RTCP)的数据包。
在电子设备1与电子设备2间的建立会话1后，其他电子设备(例如，电子设备3)可以通过以下五种方式加入到会话1中：
方式1、电子设备3可以通过E-mail、Web公告或者即时消息等方式获取到上述会话1的URI，然后向会话1发送INVITE消息，请求加入该会话1，会话1控制中心接收到该INVITE消息后，确定是否同意电子设备3加入该会话1。区别于电子设备所代表的用户的URI，上述会话1的URI用于表示电子设备1于电子设备2间建立的会话1。方式1又称Call-In方式。
方式2、上述会话1的会话1控制中心主动向电子设备3发送INVITE消息，该INVTIE消息用于邀请电子设备3加入该会话1。由于基于SIP的会话1的参与者之间通过URI建立连接，因此，上述会话1控制中心需要获取到电子设备3所代表的用户的URI，通常情况下，会话1控制中心存储有该URI。方式2又称Call-Out方式。
方式3、电子设备3向会话1控制中心发送REFER请求，触发会话1控制中心邀请电子设备3加入会话1。该REFER请求中需要携带上述会话1的URI。
方式4、电子设备3向上述会话1的参与者发送REFER请求，触发接收该REFER请求的会话1参与者邀请电子设备3加入该会话1。该REFER请求中需要携带会话1的参与者的URI。
方式5、电子设备3向上述会话1的参与者发送携带有JOIN头域的INVITE请求，来加入上述会话1。该INVITE请求中需要携带会话1的参与者的URI。
电子设备1与电子设备2间成功建立会话1后，若电子设备1需要断开与电子设备2间的会话1，如图1中S100所示，电子设备1可以直接向电子设备2发送再见BYE消息，以断开与电子设备2间的会话1。电子设备2在接收到电子设备1发送的BYE消息后，向电子设备1发送200OK消息，并断开与电子设备1间建立的会话1。
需要说明的是，SIP中的INVITE请求用于建立电子设备间的会话，发起会话创建的电子设备在接收到对端的ACK消息回复后，则认为电子设备间的会话建立成功。在已经成功建立会话的电子设备间发送INVITE请求，无法创建信息的会话。在已建立会话的电子设备间发送的INVITE请求被称为RE-INVITE请求，该RE-INVITE请求用于更改会话特性或刷新对话状态(例如，增加新的用户到会话中)。
本申请实施例提供的会话创建方法可以应用于多人会议场景中。
示例性的，针对在多人电话会议中，在已存在一个多人电话会议的情况下，需要进行以小组为单位的分组讨论，并且不想要被小组外的其他会议成员知晓讨论的内容的场景。在相关技术中，由于用于建立电子设备间SIP会话的INVITE请在已建立会话的基础上，只能用于邀请其他用户加入会话，或者更新当前会话信息，而不能用于创建新的会话，因此，当用户想要分组讨论时，需要小组成员断开现有的会话，并在参与分组讨论的小组成员之间建立新的会话。
针对这一问题，在本申请实施例提供的技术方案中，可以利用SIP中REFER消息可以携带自定义信息的特性，在电子设备1与电子设备2间建立SIP会话的情况下，电子设备1可以向电子设备2发送REFER请求。电子设备2在接收到该REFER请求后，创建与电子设备1间的SIP会话。区别于REFER请求的原有功能，上述第一REFER请求可以用于电子设备1与电子设备2间创建SIP会话。之后，电子设备1和电子设备2可以通过上述五种方式添加其他用户到该SIP会话中。如此，解决了电子设备1与电子设备2之间无法在已创建SIP会话的电子设备间创建新的SIP会话的问题，方便用户在多人会议时进行以小组为单位的分组讨论。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的会话创建方法进行详细地说明。
如图2所示，本申请实施例提供的一种会话控制系统，该会话控制系统包括第一电子设备201、第二电子设备202和第三电子设备203，其中：第一电子设备201可以通过代理服务与第二电子设备202(第三电子设备203)进行信息交互，也可以在双方获取到对方的真实网络地址后，直接进行数据交互。
在第一电子设备201与N个第二电子设备202间已创建第一会话初始协议SIP会话的情况下，第一电子设备201向第三电子设备203发送第一REFER请求，其中，上述第一REFER请求用于请求创建与第三电子设备203间的第二SIP会话，上述第三电子设备203为上述N个第二电子设备202中的至少一个，N为正整数。
第一电子设备201第二电子设备202第三电子设备203从第一电子设备201接收到第一REFER请求后，第三电子设备203向第一电子设备201发送第一响应消息；其中，上述第一REFER请求用于请求创建上述第一电子设备201与上述第三电子设备203间的第二SIP会话。
上述第一响应消息用于指示上述第三电子设备203是否同意创建上述第一电子设备201与第三电子设备203间的第二SIP会话。
第一电子设备201接收到第三电子设备203响应于上述第一REFER请求反馈的第一响应消息后，若第一响应消息指示第三电子设备203同意创建第二SIP会话，则第一电子设备201创建第二SIP会话。
如此，在第一电子设备与第二电子设备间存在第一SIP会话的情况下，第一电子设备通过向第二电子设备发送第一REFER请求的方式，请求创建与第二电子设备间的第二SIP会话，并在接收到第二电子设备发送的第一响应消息后，创建与第二电子设备间的第二SIP会话。第一电子设备可以在与第二电子设备间已经创建电话会议的基础上，与第二电子设备创建新的电话会议。
可选地，为了区分于传统的REFER消息，第一电子设备201向第三电子设备203发送第一REFER消息之前，第一电子设备201根据目标REFER参数，生成第一REFER请求，其中，上述目标REFER参数包含上述第三电子设备203的URI和第一信息，该第一信息用于指示第三电子设备203创建第二SIP会话。第三电子设备203解析上述第一REFER请求，得到该第一REFER请求中携带的目标REFER参数，并且，第三电子设备203根据目标REFER参数，确定是否创建与第一电子设备201间的第二SIP会话。
如此，第一电子设备201可以通过向第三电子设备203发送携带有第一消息的REFER请求，请求建立与第三电子设备203间的第二SIP会话。
可选地，为了能够在断开第一电子设备201与第三电子设备203间的第二SIP会话的同时，还能保留第一电子设备201与第三电子设备203间的第一SIP会话。第一电子设备201向第三电子设备203发送第二REFER请求，并断开第二SIP会话，其中，上述第二REFER请求中携带第二信息，该第二信息用于指示第三电子设备203断开与第一电子设备201间的第二SIP会话。第三电子设备203从第一电子设备201接收第二REFER请求，第三电子设备203解析上述第二REFER请求，根据第二REFER请求中携带的第二信息，断开上述第二SIP会话。
如此，第一电子设备201可以通过向第三电子设备203发送携带有第二消息的REFER请求，请求断开与第三电子设备203间的第二SIP会话。
可选地，第一电子设备201在创建与第三电子设备203间的第二SIP会话之前，第一电子设备201与第三电子设备203间可以通过发送INVITE请求的方式创建第一SIP会话。第一电子设备201向目标第二电子设备202发送邀请INVITE请求，该INVITE请求用于请求创建与上述目标第二电子设备202间的所述第一SIP会话。第一电子设备201接收第三电子设备203响应于上述INVITE请求反馈的第二响应消息，若上述第二响应消息指示上述目标第二电子设备202同意创建第一SIP会话，则第一电子设备201创建第一SIP会话，其中，上述目标第二电子设备202为上述N个第二电子设备202中的至少一个。
如此，第一电子设备201通过向第二电子202设备发送INVITE请求的方式，与第二电子设备202建立第一SIP会话。
需要说明的是，上述的第一电子设备201与N个第二电子设备202间存在已创建的第一SIP会话，第三电子设备203为上述N个第二电子设备202中的至少一个。当第一电子设备201想要与第三电子设备203间创建第二SIP会话时，第一电子设备201的用户需要在上述第一SIP会话的界面上，从上述N个第二电子设备201的标识中选择第三电子设备203的标识，进而与第三电子设备203间建立第二SIP会话。
本实施例提供一种会话创建方法，如图3所示，本实施例主要针对第一电子设备侧，该会话创建方法包括以下步骤301至步骤303：
步骤301、在第一电子设备与N个第二电子设备间已创建第一会话初始协议SIP会话的情况下，第一电子设备向第三电子设备发送第一REFER请求。
其中，上述第一REFER请求用于请求创建上述第一电子设备与上述第三电子设备间的第二SIP会话，N为正整数。
示例性的，上述第一电子设备和第三电子设备为第一SIP会话中想要在第一SIP会话的基础上创新的SIP会话的电子设备。
示例性的，第一电子设备的用户可以在第一SIP会话的界面上点击第三电子设备所属用户的标识，来触发第一电子设备向第三电子设备发送上述第一REFER请求。
可选地，在本申请实施例中，区别于上述方式3和方式4中其他电子设备在加入SIP会话时发送的REFER请求，为了能够使得REFER请求可以用于创建第一电子设备与第三电子设备间的SIP会话，上述第一REFER请求中可以包含特定的信息，以使得第三电子设备在接收到第一电子设备发送的第一REFER请求后，能够根据该请求创建与第一电子设备间的SIP会话。
示例性的，在上述步骤301之前，本申请实施例提供的会话创建方法，还可以包括以下步骤301a：
步骤301a：第一电子设备根据目标REFER参数，生成第一REFER请求。
其中，上述目标REFER参数包含上述第三电子设备的URI和第一信息，该第一信息用于指示第三电子设备创建第二SIP会话。
示例性的，基于SIP创建的会话，会话参与者间通过参与者的URI来获取对方的真实网络地址，并将信息发送给对方。因此，第一电子设备为了将第一REFER请求准确的发送的第三电子设备上，可以将上述第三电子设备的URI映射至第一REFER请求的Refer to头域中。例如，第一REFER请求的Refer to头域的值可以为whatever URI，表示该第一REFER请求可以发送至第一SIP会话的任何一个参与者。进一步的，以第三电子设备的所属用户为Bob为例，上述第一REFER请求的Refer to头域的值可以为第三电子设备的URI，例如，Refer-To:<sip:Bob@Bob.example>。
示例性的，为了使得第三电子设备能够在接收到第一REFER请求后，正确 的判断第一电子设备的意图。上述第一REFER请求中还携带有第一信息，区别于上述方式3和方式4中的REFER请求，该第一信息用于指示第三电子设备创建第二SIP会话。进一步的，上述第一信息可以位于第一REFER请求的Refer to头域中，例如，Refer-To:<sip:Bob@Bob.example；method＝invite>，该Refer-To头域中的值method＝invite，表示该第一REFER请求用于指示第三电子设备创建与第一电子设备间的第二SIP会话。
如此，第一电子设备可以根据第三电子设备的URI将上述包含目标参数的第一REFER请求发送至第三电子设备，第三电子设备在接收到该第一REFER请求后，可以根据第一REFER请求的Refer-To头域中的第一信息，确定第一电子设备想要创建与第三电子设备间的SIP会话，之后，第三电子设备可以根据该第一信息，建立与第一电子设备间的第二SIP会话。
步骤302、第一电子设备接收第三电子设备响应于上述第一REFER请求反馈的第一响应消息。
步骤303、若第一响应消息指示第三电子设备同意创建第二SIP会话，则第一电子设备创建第二SIP会话。
示例性的，上述第一电子设备接收到第三电子设备发送的同意创建第二SIP会话的响应后，创建与第三电子设备间的第二SIP会话。上述第一电子设备与第三电子设备间创建新的SIP会话后，不会断开上述第一SIP会话。即，上述第一电子设备与上述第三电子设备间同时存在第一SIP会话和新创建的SIP会话。
示例性的，上述第二SIP会话创建成功后，邀请其他用户加入该会话的方式参照上述方式1至方式5，上述方式1至方式5中对其他用户加入会话的方式在进行了详细描述，为了防止重复，在此不再赘述。
如此，在第一电子设备与第二电子设备间存在第一SIP会话的情况下，第一电子设备通过在REFER请求中集成会话创建功能，使得第一电子设备可以通过向第三电子设备发送第一REFER请求，来创建第一电子设备与第三电子设备间的第二SIP会话，使得第一SIP会话中的会话参与者在参与第一SIP会话过程中，能够通过REFER请求创建第一SIP会话中的会话参与者间的第二SIP会话，如此，在第一电子设备与第二电子设备间的第一SIP会话不断开的情况下，创 建第二SIP会话，使得用户可以在多人会话的基础上，进行分组会话。
可选地，在本申请实施例中，当第一电子设备与第三电子设备间建立第二SIP会话成功后，为了使得用户不受第一SIP会话中语音的干扰，同时也不干扰第一SIP会话中的其他用户，可以控制第一电子设备和第三电子设备中，第一SIP会话与第二SIP会话间的音频传输方向及音量。
示例性的，以第一电子设备为例，第一电子设备上第一SIP会话与第二SIP会话的音频控制可以通过以下至少两种控制方法进行控制：
控制方法1：
在方式1中，第一电子设备根据用户激活的当前SIP会话界面，来控制音频的输入。
示例性的，上述步骤303之后，本申请实施例提供的会话创建方法，还可以包括以下步骤303a1和步骤303a2：
步骤303a1、第一电子设备在目标SIP会话的会话界面处于激活状态的情况下，采集用户的语音信号。
步骤303a2、第一电子设备将上述语音信号输入至目标SIP会话中。
其中，上述目标SIP会话包括第一SIP会话或第二SIP会话。
示例性的，当第一SIP会话的会话界面处于激活状态(即第一SIP会话的对话框为电子设备当前活动对话框，通常情况下，操作系统只允许一个对话框处于激活状态)，且第二SIP会话的会话界面处于非激活状态时，第一电子设备控制用户的音频输入到第一SIP会话中，并切断第二SIP会话的音频输入。当第一SIP会话的会话界面处于非激活状态，且第二SIP会话的会话界面处于激活状态时，第一电子设备控制用户的音频输入到第二SIP会话中，并切断第一SIP会话的音频输入。即，第一电子设备控制用户的音频输入到当前激活的SIP会话中。
示例性的，第一电子设备同时输出第一SIP会话和第二SIP会话的音频，且为了用户能够在听到第二SIP会话的内容的同时，还能听到第一SIP会话的内容，上述第一SIP会话的第一音量小于上述第二SIP会话的第二音量。
控制方法2：
在方式2中，第一电子设备可以根据用户对第二SIP界面上的语音控制按 钮的操作，来控制第一电子设备的用户的声音是否输入到第一SIP会话中。同时，也可以结合方式1中的方法，对第一电子设备的音频输入进行控制。
示例性的，上述步骤303之后，本申请实施例提供的会话创建方法，还可以包括以下步骤303b1至步骤303b3：
步骤303b1、第一电子设备显示第二SIP会话的会话界面，该会话界面上设置有目标控件。
步骤303b2、第一电子设备采集用户的语音信号。
步骤303b3、第一电子设备根据目标控件的开启状态，控制上述语音信号是否输入至第一SIP会话中。
示例性的，第一电子设备可以通过MIC采集用户的语音信号。上述目标控件可以为具有开启和关闭功能的控件，当该目标控件处于开启状态时，第一电子设备可以将采集到的语音信号输入至第一SIP会话中，使得第一SIP会话中的成员能够接收到该语音信号。
示例性的，第一电子设备接收用户对上述第二SIP会话的会话界面上目标控件的第一输入，响应与该第一输入，第一电子设备控制第一电子设备的音频输入到第一SIP会话中。
示例性的，第一电子设备接收用户对上述第二SIP会话的第一界面上语音控制控件的第二输入，响应与该第二输入，第一电子设备控制第一电子设备的音频停止输入到第一SIP会话中。
示例性的，第一电子设备始终能够接收到第一SIP会话的音频输出。
举例说明，第二SIP会话的会话界面上显示有语音控制控件(即上述目标控件)，当用户激活该控件时，第一电子设备可以将用户的声音输入到第一SIP会话中，如此，第一SIP会话中的其他用户便可听到第一电子设备的用户的声音。当用户取消激活该控件时，第一电子设备停止向第一SIP会话中输入用户的声音，如此，第一SIP会话中的其他用户便不能听到第一电子设备的用户的声音。
需要说明的是，上述第一电子设备控制音频输入的两种方式，同样适用于第三电子设备。为了防止重复，在此不再赘述。
如此，第一电子设备和第三电子设备可以通过上述两种方式控制音频在第一SIP会话和第二SIP会话的输入。使得第二SIP会话的内容不被第一SIP会话中的其他用户所获取，同时，也能保证第一电子设备或第三电子设备的用户能够获取第一SIP会话的内容，例如，第一SIP会话主持人结束小组讨论的通知。
可选地，在本申请实施例中，当第一电子设备的所属用户想要断开与第三电子设备所属用户的第二SIP会话时，若按照SIP所规定的向第三电子设备发送BYE消息，则会断开与第三电子设备间的第一SIP会话。因此，第一电子设备需要向第三电子设备发送含有特殊消息的请求，以断开与第三电子设备间的第二SIP会话。
示例性的，上述步骤303之后，本申请实施例提供的会话创建方法，还可以包括以下步骤303c：
步骤303c：第一电子设备向第三电子设备发送第二REFER请求，并断开第二SIP会话。
其中，上述第二REFER请求中携带第二信息，该第二信息用于指示第三电子设备断开与第一电子设备间的第二SIP会话。
示例性的，由于按照SIP规定的会话断开方式，第一电子设备向第三电子设备发送BYE消息会断开第一电子设备与第三电子设备间的第一SIP会话，而不是断开第一电子设备与第三电子设备间的第二SIP会话。因此，第一电子设备可以向第三电子设备发送携带有第二信息的第二REFER请求，该第二信息用于指示第三电子设备断开与第一电子设备间的第二SIP会话，并且，结合上述第一REFER请求的Refer-To头域的值，上述第二REFER请求的Refer-To头域中，包括第三电子设备的URI以及上述第二信息。举例说明，上述第二REFER请求的Refer-To头域的值可以为Refer-To:<sip:Bob@Bob.example；method＝bye>。
如此，当第一电子设备想要断开与第三电子设备间的第二SIP会话，且不断开第一电子设备与第三电子设备间的第一SIP会话时，可以通过向第三电子设备发送携带有第二信息的第二REFER请求的方式，断开与第三电子设备间的第二SIP会话。
可选地，在本申请实施例中，参照如图1所示的SIP会话创建方法，上述 第一电子设备可以通过向第二电子设备发送INVITE请求的方式，创建与第二电子设备间的第一SIP会话。
示例性的，上述步骤301中的步骤第一电子设备向第三电子设备发送第一REFER请求之前，本申请实施例提供的会话创建方法，还可以包括以下步骤301b1至步骤301b3：
步骤301b1：第一电子设备向目标第二电子设备发送邀请INVITE请求，该INVITE请求用于请求创建与上述目标第二电子设备间的所述第一SIP会话。
步骤301b2：第一电子设备接收第三电子设备响应于上述INVITE请求反馈的第二响应消息。
步骤301b3：若上述第二响应消息指示上述目标第二电子设备同意创建第一SIP会话，则第一电子设备创建第一SIP会话。
其中，上述目标第二电子设备为上述N个第二电子设备中的至少一个。
示例性的，上述第一SIP会话的创建方法，可以按照图1所示的电子设备间创建SIP会话的方法进行创建，第一电子设备通过代理服务器向第二电子设备发送INVITE请求，该INVITE请求中携带第二电子设备的URI。与第二电子设备间的第一SIP会话创建成功后，可以通过上述方式1至方式5所述的方法向该第一SIP会话中添加其他用户。
如此，第一SIP会话的创建方法与第二SIP会话的创建方法完全不同，第一SIP会话是第一电子设备向第二电子设备发送INVITE请求创建的，而第二SIP会话是在第一SIP会话存在的情况下，第一电子设备向第三电子设备发送第一REFER请求创建的。
本实施例还提供另一种会话创建方法，如图4所示，本实施例主要针对第二电子设备侧，该会话创建方法包括以下步骤401和步骤402：
步骤401、在第一电子设备与N个第二电子设备间已创建第一SIP会话的情况下，第三电子设备从第一电子设备接收第一REFER请求。
其中，上述第一REFER请求用于请求创建上述第一电子设备与上述第三电子设备间的第二SIP会话，N为正整数。
步骤402、响应于上述第一REFER请求，第三电子设备向第一电子设备发 送第一响应消息。
其中，上述第一响应消息用于指示上述第三电子设备是否同意创建上述第一电子设备与第三电子设备间的第二SIP会话。
示例性的，第三电子设备在接收到第一电子设备发送的第一REFER请求后，通过对该请求进行解析，得到用于指示第三电子设备与第一电子设备间建立第二SIP会话的第一信息后，第三电子设备在其屏幕上显示提示信息，提示用户是否创建与第一电子设备间的第二SIP会话，并在用户确认同意后，向第一电子设备发送第一响应消息。该第一响应消息用于指示第三电子设备同意创建与第一电子设备间的第二SIP会话。在第一电子设备接收到第三电子设备发送的第一响应消息后，则成功创建与第三电子设备间的第二SIP会话。若第三电子设备的用户拒绝第一电子设备创建与第三电子设备间的第二SIP会话请求，则此次第二SIP会话创建失败。
可选地，第三电子设备在接收到第一电子设备发送的第一REFER请求后，可以根据该请求中的特定的信息，确定第一电子设备发送的该第一REFER请求的具体用途。
示例性的，在上述步骤401之后，本申请实施例提供的会话创建方法，还可以包括以下步骤401a1和步骤401a2：
步骤401a1：第三电子设备解析上述第一REFER请求，得到该第一REFER请求中携带的目标REFER参数。
步骤401a2：第三电子设备根据目标REFER参数，确定是否创建与第一电子设备间的第二SIP会话。
示例性的，上述第三电子设备解析第一REFER请求，包括解析第一REFER请求的Refer-To头域的值，例如，第三电子设备解析Refer-To头域的值，得到第一信息method＝invite，并确定该第一REFER请求用于指示第三电子设备创建第二SIP会话。
如此，第三电子设备可以根据接收到的第一REFER请求，确定第一电子设备想要建立与第三电子设备间的第二SIP会话。
可选地，第三电子设备按照上述第一电子设备的两种控制音频输入的方式 控制第三电子设备上的第一SIP会话和第二SIP会话的音频输入和输入，为了防止重复，在此不再赘述。
可选地，在第三电子设备与第一电子设备间的第二SIP会话创建成功后，第三电子设备可以主动或被动断开与第一电子设备间的第二SIP会话。
示例性的，在上述步骤402之后，本申请实施例提供的会话创建方法，还可以包括以下步骤402a1至步骤402a3：
步骤402a1：第三电子设备接收第一电子设备发送的第二REFER请求。
步骤402a2：第三电子设备解析上述第二REFER请求，得到第二REFER请求中携带的第二信息。
步骤402a3、第三电子设备根据第二REFER请求中携带的第二信息，断开上述第二SIP会话。
示例性的，上述第三电子设备在接收到第一电子设备发送的第二REFER请求后，通过解析该第二REFER请求的Refer-To头域的值，得到第二信息(即上述method＝bye)，进而判断出第一电子设备想要断开与第三电子设备间的第二SIP会话。之后，第三电子设备向第一电子设备发送确认消息，并断开上述第二SIP会话。
示例性的，第三电子设备同样可以向第一电子设备发送第二REFER请求，主动断开与第一电子设备间的第二SIP会话。
如此，由于上述断开SIP会话过程没有发送BYE消息，因此，第三电子设备可以在不断开第一SIP会话的基础上断开与第一电子设备间的第二SIP会话。
需要说明的是，上述第三电子设备与第一电子设备的在本申请实施例中具有相同的功能和作用，因此，上述第三电子设备具有第一电子设备的所有特征并可以执行上述第一电子设备执行的所有步骤，反之亦然。
本申请实施例提供的会话创建方法，在第一电子设备与第三电子设备间存在SIP会话的情况下，第三电子设备在接收到第一电子设备发送第一REFER请求后，根据第一REFER请求中携带的第一信息，在第一电子设备与第三电子设备间存在第一SIP会话的基础上，创建与第一电子设备间的第二SIP会话，并且不会断开与第一电子设备间的第一SIP会话。如此，在不断开第一SIP会话的前 提下，创建第二SIP会话，可以实现多人会议中，以小组的形式进行分组讨论，而又不会影响到其他小组外成员。
需要说明的是，本申请实施例提供的会话创建方法，执行主体可以为会话创建装置，或者该会话创建装置中的用于执行加载会话创建方法的控制模块。本申请实施例中以会话创建装置执行加载会话创建方法为例，说明本申请实施例提供的会话创建方法。
需要说明的是，本申请实施例中，上述各个方法附图所示的。会话创建方法均是以结合本申请实施例中的一个附图为例示例性的说明的。具体实现时，上述各个方法附图所示的会话创建方法还可以结合上述实施例中示意的其它可以结合的任意附图实现，此处不再赘述。
