Description

用于调整编码速率的方法和装置 技术领域
本发明实施例涉及通信领域，更具体地，涉及用于调整编码速率的方法和装置。
背景技术
在无线语音传输过程中，为了满足带宽的限制以及距离方面的要求，必须对语音的数据信息进行压缩，即对语音数据进行编码，将模拟信号转化为数字信号。随着移动通信的发展，对语音压缩编码的要求越来越高，不但要求编码码率较低以增加***容量，而且要求合成音质较高以保证通话质量。因此，需要根据当前网络情况，对发送方的编码速率进行调整，以便于提供更高质量的语音服务，同时充分利用***资源。
在现有技术中，网络设备可以根据当前的网络状况对终端设备的编码速率进行调整，例如当前网络是否发生拥塞、链路质量是否够好等等。也就是说，如果网络设备发现当前网络状况比较差，则通知终端设备进行降速；如果网络设备发现当前网络状况比较好，则通知终端设备进行升速。在一些***的语音业务中，例如长期演进(Long Term Evolution，简称为“LTE”)***，发送端和接收端是采用相同速率进行编解码的。因此，当接收端接收到该接收端所属网络设备发送的网络拥塞指示时，会直接进行编码速率的降速调整或者通知发送端进行编码速率的降速调整，否则，该接收端直接进行编码速率的升速调整或者通知发送端进行编码速率的升速调整。
但是，在上述现有技术中，终端设备速率调整都只考虑了单侧网络的链路状态，在没有收到网络拥塞指示的情况下，该终端设备会直接对编码速率进行升速调整，并不会综合考虑通信双方的链路状态，这样会导致该终端设备调整后的编码速率不被对端允许，编码速率被频繁地升降，从而影响用户体验。
发明内容
有鉴于此，本发明实施例提供了一种用于调整编码速率的方法和装置，能够避免编码速率被频繁升降的问题，从而节省信令开销，提高用户体验。
第一方面，提供了一种用于调整编码速率的方法，包括：第一终端设备接收第二终端设备发送的第一上行编码速率调整请求消息，该第一上行编码速率调整请求消息用于触发该第一终端设备进行上行编码速率的调整，该第一上行编码速率调整请求消息携带第一编码速率，该第二终端设备为与该第一终端设备进行通信的对端设备；在该第一终端设备确定该第一编码速率大于该第一终端设备当前使用的上行编码速率时，该第一终端设备向第一网络设备发送咨询消息，该咨询消息用于触发与该第一网络设备进行编码速率调整的协商，该咨询消息携带该第一编码速率，该第一终端设备在该第一网络设备的覆盖范围内。
这样，第一终端设备根据收到的第一编码速率确定第二终端设备的升速请求时，不会立即进行编码速率的升速调整，而是会与本端的第一网络设备进行协商，综合考虑本端和对端两侧链路的网络状态，判断是否需要进行编码速率的升速调整，这样能够避免编码速率被频繁升降的问题，从而节省信令开销，提高用户体验。
在第一方面的第一种可能的实现方式中，在该第一终端设备向第一网络设备发送咨询消息之后，该方法还包括：该第一终端设备接收该第一网络设备发送的响应消息，该响应消息携带该第一网络设备允许调整的参考编码速率；该第一终端设备根据该响应消息，判断是否需要进行编码速率的升速调整。
具体地，该第一终端设备可以接收第一网络设备发送的参考编码速率，根据该参考编码速率，判断是否需要进行编码速率的升速调整。
结合第一方面的上述可能的实现方式，在第一方面的第二种可能的实现方式中，该第一上行编码速率调整请求消息为实施控制协议RTCP消息或携带编码模式请求的实时传输协议RTP CMR消息。
结合第一方面的上述可能的实现方式，在第一方面的第三种可能的实现方式中，该咨询消息为无线资源控制RRC消息或层2控制消息，例如，媒体接入控制的控制单元MAC CE消息。
在本发明实施例的某些方面中，该第一终端设备在接收第二终端设备发送的第一上行编码速率调整请求消息之后，可以根据第一终端设备自身的测量结果，判断是否接受第一上行编码速率调整请求消息中携带的第一编码速率，确定该第一终端设备允许调整的参考编码速率。
可选地，若该第一终端设备接受该第一编码速率，则将该第一编码速率确定为该参考编码速率；若该第一终端设备不接受该第一编码速率，则将该第一终端设备允许的最大编码速率确定为该参考编码速率。
第二方面，提供了一种用于调整编码速率的方法，包括：第一网络设备接收第一终端设备发送的咨询消息，该咨询消息携带与该第一终端设备通信的第二终端设备所请求的第一编码速率，该第一编码速率大于该第一终端设备当前使用的上行编码速率，其中，该第一终端设备在该第一网络设备的覆盖范围内，该第二终端设备为与该第一终端设备进行通信的对端设备；该第一网络设备根据当前网络状态和该第一编码速率，确定该第一网络设备允许调整的参考编码速率。
这样，该第一网络设备在接收到第一终端设备发送的咨询消息后，会综合考虑自身的网络状态和该咨询消息中携带的编码速率，确定允许调整的参考编码速率。因此，确定出的参考编码速率综合考虑了本端和对端两侧链路的网络状态，以供第一终端设备进行参考，这样能够避免编码速率被频繁升降的问题，从而节省信令开销，提高用户体验。
在第二方面的第一种可能的实现方式中，该第一网络设备根据当前网络状态和该第一编码速率，确定该第一网络设备允许调整的参考编码速率，包括：若该第一网络设备根据该当前网络状态，确定接受该第一编码速率，则该第一网络设备将该第一编码速率确定为该参考编码速率；若该第一网络设备根据该当前网络状态，确定不接受该第一编码速率，则该第一网络设备将允许的最大编码速率确定为该参考编码速率。
结合第二方面的上述可能的实现方式，在第二方面的第二种可能的实现方式中，在该第一网络设备根据当前网络状态和该第一编码速率，确定该第一网络设备允许调整的参考编码速率之后，该方法还包括：该第一网络设备向该第一终端设备发送响应消息，该响应消息携带该参考编码速率。
结合第二方面的上述可能的实现方式，在第二方面的第三种可能的实现方式中，该咨询消息为无线资源控制RRC消息或层2控制消息，例如，媒体接入控制的控制单元MAC CE消息。

这样，该第一终端设备根据收到的编码速率确定第一网络设备的升速请求时，不会立即进行编码速率的升速调整，而是会与通信对端第二终端设备进行协商，综合考虑本端和对端两侧链路的网络状态，判断是否需要进行编码速率的升速调整，这样能够避免编码速率被频繁升降的问题，从而节省信令开销，提高用户体验。
在第三方面的第一种可能的实现方式中，在该第一终端设备向该第二终端设备发送咨询消息之后，该方法还包括：该第一终端设备接收该第二终端设备发送的响应消息，该响应消息携带该第二终端设备允许调整的参考编码速率；该第一终端设备根据该响应消息，判断是否需要进行编码速率的升速调整。
结合第三方面的上述可能的实现方式，在第三方面的第二种可能的实现方式中，该第一上行编码速率调整请求消息为无线资源控制RRC消息或层2控制消息，例如，媒体接入控制的控制单元MAC CE消息。
结合第三方面的上述可能的实现方式，在第三方面的第三种可能的实现方式中，该咨询消息为实施控制协议RTCP消息或携带编码模式请求的实时传输协议RTP CMR消息。
第四方面，提供了一种用于调整编码速率的方法，包括：第一终端设备接收第一网络设备发送的第一编码速率，该第一终端设备在该第一网络设备的覆盖范围内；该第一终端设备接收第二终端设备发送的第二编码速率，该第二终端设备为与该第一终端设备进行通信的对端设备；该第一终端设备根据该第一编码速率和该第二编码速率，判断是否需要进行编码速率的升速调整。
可选地，该第一终端设备接收第一网络设备发送的第一编码速率，包括：
该第一终端设备接收该第一网络设备发送的第一上行编码速率调整请求消息，该第一上行编码速率调整请求消息用于触发该第一终端设备进行上 行编码速率的调整，该第一上行编码速率调整请求消息携带第一编码速率。
可选地，该第一终端设备接收第二终端设备发送的第二编码速率，包括：
该第一终端设备接收该第二终端设备发送的第二上行编码速率调整请求消息，该第二上行编码速率调整请求消息用于触发该第一终端设备进行上行编码速率的调整，该第二上行编码速率调整请求消息携带第二编码速率。
因此，本发明实施例的用于调整编码速率的方法，综合考虑了本端和对端两侧链路的网络状态，通过接收与本端链路状态对应的第一编码速率和与对端链路状态对应的第二编码速率，判断是否需要进行编码速率的升速调整，这样能够避免编码速率被频繁升降的问题，从而节省信令开销，提高用户体验。

结合第四方面的上述可能的实现方式，在第四方面的第二种可能的实现方式中，该第一终端设备根据该第一编码速率和该第二编码速率，判断是否需要进行编码速率的升速调整，还包括：若该第二编码速率大于该第一编码速率，则该第一终端设备拒绝进行编码速率的升速调整。
具体地，第一网络设备可以根据自身的网络状况，例如网络负载情况，预先为第一终端设备设置一个速率门限值，即最大编码速率。这样，该第一终端设备在收到第二编码速率时，一旦发现第二编码速率大于当前正在使用的编码速率时，则将该第二编码速率与最大编码速率进行比较，从而判断是否需要进行编码速率的升速调整，这样能够节省信令开销，提高用于体验。

结合第四方面的上述可能的实现方式，在第四方面的第五种可能的实现方式中，该方法还包括：若该第一终端设备先接收到该第一编码速率，则该第一终端设备在接收到该第一上行编码速率调整请求消息时将该第一编码速率与该第一终端设备当前使用的上行编码速率进行比较；若该第一编码速率大于该第一终端设备当前使用的上行编码速率，则该第一终端设备开启定时器，并在该定时器超时之前等待该第二上行编码速率调整请求消息；该第一终端设备根据该第一编码速率和该第二编码速率，判断是否需要进行编码速率的升速调整，包括：若在该定时器超时之前，该第一终端设备接收到该第二编码速率，则该第一终端设备根据该第一编码速率和该第二编码速率，判断是否需要进行编码速率的升速调整。
