技术领域
本申请涉及通信领域但不限于通信领域，尤其涉及一种融合设备媒体控制方法、装置及通信终端。

即使目前的移动设备(User Equipment，UE)如手机，尤其是智能手机己经普及了前置摄像头和视频流的能力，即己经可以在UE上实现视频通话。但是，由于移动设备的硬件设备的限制、多媒体能力的限制，并不能体验大屏、高清的多媒体通信。且从未来的角度看，多媒体通信的能力，完全不是简单的移动设备可以构建或承载的，如支持全息投影的通信。为了解决该问题出现了一种融合通信技术，将具有大屏、高清甚至全息投影等多媒体功能的设备作为融合设备通过UE引入IP多媒体子系统(IP Multimedia Subsystem，IMS)，利用该融合设备的多媒体功能实现与远端UE的媒体流交互，进而实现更好的多媒体通信体验。
但在融合通信技术实际使用中，当用于传输媒体流的通信连接网络质量差影响媒体流的传输时，会在很大程度上影响多媒体通信，降低用户体验的满意度。

具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，下面通过具体实施方式结合附图对本申请实施例作进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
为了实现融合通信技术中用于传输媒体流的通信连接网络质量差时，如何减少对媒体流的传输影响，保证多媒体通信的正常进行。本实施例提供了一种融合设备媒体控制方法，参见图1所示，可包括：
S101：通信终端在对融合设备与远端设备之间的媒体流中转过程中，检测到用于媒体流传输的通信连接的质量参数与预设质量参数阈值不匹配时，获取目标媒体描述信息。
本实施例中的远端设备可以是远端的通信终端，也可以是远端的媒体服务器，例如视频服务器等。本实施例中的通信终端包括但不限于各种具有通信能力的终端类用户设备，如包括但不限于智能手机、Pad类平板电脑、笔记本电脑、智能穿戴设备(智能手表、手环等)或其它用户智能设备。
本实施例中，融合设备包括但不限于有多媒体能力，同时具备近距离通信能力、远端通信能力的设备和/或具有多媒体能力和近距离通信能力，而不具备远端通信能力的设备。本实施例中的近距离通信包括但不限于蓝牙、红外、WiFi、NFC(Near Field Communication，近场通信)。
本实施例中，融合设备可以通过通信终端引入IP多媒体子系统(IP Multimedia Subsystem，IMS)，融合设备可利用多媒体功能获取通信终端的语音和/或视频媒体流，将所获取的语音和/或视频媒体流通过通信终端传送到远端设备。融合设备也可通过通信终端接收远端设备的语音和/或视频媒体流，并利用多媒体功能将所获取的语音和/或视频媒体流展现给用户。应当理解的是，本实施例中的媒体流包括但不限于语音媒体流和视频媒体流。本实施例中的融合设备发出的媒体流可通过通信终端转发到远端设备，远端设备发送的媒体流也可以通过通信终端转发到融合设备。
本实施例中，融合设备与通信终端之间可通过近距离通信连接，也可以通过其远端通信能力与通信终端连接。
本实施例中，通信连接的质量参数可以是至少一个用于表征通信连接的质量参数，例如包括但不限于信号功率、误码率、丢包率、传输时延、信号强度中的至少一种，对应的预设质量参数阈值包括信号功率阈值、误码率阈值、丢包率阈值中的至少一种；当检测到的信号功率小于预设信号功率阈值时，则表明信号功率与信号功率阈值不匹配，当检测到的误码率大于预设误码率阈值时，则表明误码率与误码率阈值不匹配，当检测到的丢包率大于预设丢包率阈值时，则表明丢包率与丢包率阈值不匹配；当然，应当理解的是也可以结合至少两种质量参数进行判断，在此不再赘述。
本实施例中，根据用于媒体流传输的通信连接质量的检测结果可以确定具体的媒体切换方式，从而确定获取通信终端的媒体描述信息而将媒体流全部回落到通信终端上，还是获取通信终端和融合设备媒体描述信息从而将媒体流部分回落到通信终端上，或是获取融合设备的新的媒体描述信息实现媒体流降码率。
S102：通信终端根据获取的目标媒体描述信息发起建立与远端设备之间的用于媒体流交互的新媒体面。
本实施例中，当通信终端获取的自身的媒体描述信息而将媒体流全部回落到通信终端上时，该步骤则发起建立通信终端自身与远端设备之间的新媒体面；当通信终端获取的是通信终端和融合设备媒体描述信息时，该步骤则发起建立通信终端与远端设备之间的新媒体面以及融合设备与远端设备之间的新媒体面；当通信终端获取的是融合设备的新的媒体描述信息时，该步骤则发起建立通信终端与远端设备之间的新媒体面以及融合设备与远端设备之间的新媒体面。应当理解的是，本步骤中建立的新媒体面包括一个或一个以上媒体流。
如上所示，在本实施例中，通信终端检测到用于媒体流传输的通信连接质量差时，可能是融合设备和通信终端之间进行媒体流传输的通信连接 质量差(当融合设备与通信终端通过近距离通信建立连接时，此时可简称为近距离通信质量差)，也可能是通信终端与远端通信之间进行媒体流传输的通信连接质量差(本实施例可称这种情况为远端通信质量差)。
在本实施例中，当通信终端检测到与融合设备之间进行媒体流传输的通信连接的质量参数与预设质量参数阈值不匹配时(也即通信终端检测到与融合设备之间进行媒体流传输的通信连接质量差时)，通信终端可采用媒体流全部回落、部分回落以及媒体流降码率方式中的任意一种方式，本实施例下面对上述几种方式进行示例说明。
采用媒体流全部回落到通信终端时，此时通信终端获取的目标第一媒体描述信息包括自身的第一媒体描述信息；
此时，通信终端根据目标媒体描述信息发起建立与远端设备之间的用于媒体流交互的新媒体面包括：
通信终端根据自身的第一媒体描述信息(具体可采用SDP(Session Description Protocol，会话描述协议)结构)经由注册服务器建立自身与远端设备之间的用于媒体流交互的第一媒体面。
具体的，通信终端可向注册服务器发送包含该第一媒体描述信息的媒体切换请求建议通信终端与远端设备之间的第一媒体面，媒体流从融合设备回落到通信终端，并可以继续以较好的网络质量传输媒体流。本实施例中的媒体切换请求包括但不限于媒体修改请求、重新邀请(Re-INVITE)请求、更新数据(UPDATE)请求中的任意一种。具体建立媒体面的方式可以是任意媒体面建立方式，在此不再赘述。
采用媒体流部分回落到通信终端时，此时通信终端获取的目标媒体描述信息可包括自身的第二媒体描述信息和融合设备的第三媒体描述信息；此时，通信终端根据目标媒体描述信息发起建立与远端设备之间的用于媒体流交互的新媒体面包括：通信终端根据第二媒体描述信息和第三媒体信息经由注册服务器建立自身与远端设备之间的第二媒体面和融合设备与所 述远端设备之间的第三媒体面，从而将一部分媒体流回落到通信终端上，另一部分媒体流仍在融合设备与远端设备之间传输。
本实施例中，第二媒体描述信息和第三媒体描述信息对应的媒体流不同，例如：
一种示例中，第二媒体描述信息对应的媒体流的带宽大于第三媒体描述信息对应的媒体流的带宽；此时则将大带宽的媒体流(例如视频媒体流)部分回落到通信终端上，小带宽的媒体流(例如语音媒体流)部分在融合设备与远端设备之间传输；
在另一种示例中，第二媒体描述信息对应的媒体流为通信终端的媒体能力支持的媒体流；第三媒体描述信息对应的媒体流为通信终端的媒体能力不支持的媒体流。
采用媒体流降码率时，通信终端获取的目标媒体描述信息包括融合设备的第四媒体描述信息，此时的第四媒体描述信息中包含用于表征第一新媒体流码率的信息，且该第一新媒体流码率小于融合设备当前传输媒体流使用的码率；此时，通信终端根据目标媒体描述信息发起建立与远端设备之间的用于媒体流交互的新媒体面包括：然后通信终端根据获取的第四媒体描述信息经由注册服务器建立融合设备与远端设备之间的用于媒体流交互的第四媒体面，实现媒体流降码率传输。
应当理解的是，上述三种方式可以根据具体情况灵活选择一种或多种进行结合，例如可以根据通信终端自身的媒体能力、具体的通信连接质量等确定采用全部回落还是部分回落，还是媒体流降码率传输。
在本实施例中，当检测到远端通信质量差时，通信终端也可采用媒体流降码率的方式。此时通信终端检测到与远端设备之间进行媒体流传输的通信连接质量差(也即通信终端检测到与远端设备之间进行媒体流传输的通信连接的质量参数与预设质量参数阈值不匹配)时，获取的目标媒体描述信息包括融合设备的第五媒体描述信息，该第五媒体描述信息中包含用 于表征第二新媒体流码率的信息，该第二新媒体流码率小于融合设备当前传输媒体流使用的码率；通信终端根据获取的第五媒体描述信息经由注册服务器建立融合设备与远端设备之间的用于媒体流交互的第五媒体面，实现媒体流降码率传输。
应当理解的是，本实施例中媒体描述信息根据具体应用场景还可包括但不限于麦克风参数、扬声器参数、摄像头参数和屏幕参数中的至少一种。
通过本实施例提供的融合设备媒体控制方法，可以实现在融合设备接入IMS与远端设备进行媒体流通信过程中，在网络质量不佳时，通过上述适时的媒体切换尽可能保证为用户继续提供多媒体通信(例如包括但不限于各种多媒体通话、直播等)的体验。同时可提升大带宽的媒体设备作为融合设备接入IMS，在各种网络覆盖场景下的兼容性，进而可进一步提升用户的多媒体通信体验。
为了实现融合通信技术中用于传输媒体流的通信连接网络质量差时，如何减少对媒体流的传输影响，保证多媒体通信的正常进行。本实施例提供了一种融合设备媒体控制装置，该融合设备媒体控制装置适用于通信终端中，参见图2所示，其包括：
监测模块21，用于在通信终端中转融合设备与远端设备之间的媒体流过程中，检测到用于媒体流传输的通信连接的质量参数与预设质量参数阈值不匹配时，获取目标媒体描述信息，具体检测和获取媒体描述信息的过程参见实施例一所示，在此不再赘述。
媒体切换控制模块22，配置为根据目标媒体描述信息发起建立与远端设备之间的用于媒体流交互的新媒体面，具体过程参见实施例一所示，在此也不再赘述。
应当理解的是，本实施例中监测模块21和媒体切换控制模块22的上述功能可通过通信终端中的处理器实现。
本实施例还提供了一种通信终端，参见图3所示，该通信终端包括处理器301、存储器302及通信总线303；
通信总线303配置为实现处理器301和存储器302之间的连接通信；
处理器用于执行存储器中存储的一个或者多个程序，以实现如实施例一所示的融合设备媒体控制方法的步骤。
本实施例还提供一种计算机存储介质，所述计算机可读存储介质存储有一个或者多个程序，所述一个或者多个程序被一个或者多个处理器执行，以实现如上实施例一所示的融合设备媒体控制方法的步骤。
该计算机存储介质可为非瞬间存储介质。
为了更好的理解本申请，本实施例结合几种具体的示例应用对本申请做进一步示例性说明。在本示例中，通信终端为UE，远端设备为远端UE，媒体描述信息采用SDP结构，融合设备与UE之间采用近距离通信实现连接。

S602：融合设备通过UE获得网络接入，例如UE作为4G路由器为融合设备提供WiFi热点；融合设备的媒体流由UE中转。
S603：UE中转媒体流，并与远端UE交互媒体流。
S604：UE检测到UE与融合设备之间的近场通信质量不佳，无法承载大带宽部分媒体流(例如视频媒体流或其他大带宽媒体流)。
S605：UE使用融合设备的SDP(小带宽媒体流(例如语音媒体流)部分对应的SDP)，与UE自身的媒体面SDP(大带宽部分媒体流对应的SDP)，构造出一个包含上述两类媒体流的SDP，向远端UE发起媒体切换请求，发送Re-INVITE到IMS。
S606：IMS转发Re-INVITE到远端UE。
S607：远端UE回200OK。
S608：UE收到200OK。
S609：UE回ACK。
S610：远端UE收到ACK。
S611：此时媒体切换完成，UE和融合设备都与远端UE建立媒体面，大带宽部分媒体流从融合设备回落到UE，并可以继续以较好的网络质量传输媒体流；小带宽部分媒体流还按切换前的方式，在融合设备与远端UE之间传输。
