目前，已知一种无线通信技术，一个终端设备可以对需要发送至对端(也可以称为接收端)的数据(例如，声音数据或图像数据等)进行编码，并将编码后的数据经由所接入的网络设备(例如，接入网设备)发送至对端。

具体实施方式
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在本说明书中使用的术语“部件”、“模块”、“系统”等用于表示计算机相关的实体、硬件、固件、硬件和软件的组合、软件、或执行中的软件。例如，部件可以是但不限于，在处理器上运行的进程、处理器、对象、可执行文件、执行线程、程序和/或计算机。通过图示，在计算设备上运行的应用和计算设备都可以是部件。一个或多个部件可驻留在进程和/或执行线程中，部件可位于一个计算机上和/或分布在2个或更多个计算机之间。此外，这些部件可从在上面存储有各种数据结构的各种计算机可读介质执行。部件可例如根据具有一个或多个数据分组(例如来自与本地系统、分布式系统和/或网络间的另 一部件交互的二个部件的数据，例如通过信号与其它系统交互的互联网)的信号通过本地和/或远程进程来通信。
本发明实施例的方案可以应用于现有的蜂窝通信系统，如全球移动通讯(英文全称可以为：Global System for Mobile Communication，英文简称可以为：GSM)，码分多址(英文全称可以为：Code Division Multiple Access，英文简称可以为：CDMA)，宽带码分多址(英文全称可以为：Wideband Code Division Multiple Access，英文简称可以为：WCDMA)，通用分组无线业务(英文全称可以为：General Packet Radio Service，英文简称可以为：GPRS)，通用移动通信(英文全称可以为：Universal Mobile Telecommunications System，英文简称可以为：UMTS)，长期演进(英文全称可以为：Long Term Evolution，英文简称可以为：LTE)等系统中，尤其应用于4.5G的LTE演进系统和5G的无线通信系统。所适用的通信主要是针对语音和数据通信的。通常来说，一个传统基站适用的连接数有限，也易于实现。
下一代移动通信系统将不仅支持传统的通信，还将支持M2M(英文全称可以为：Machine to Machine)通信，或者叫做MTC(英文全称可以为：Machine Type Communication)通信。根据预测，到2020年，连接在网络上的MTC设备将会达到500到1000亿，这将远超现在的连接数。对M2M类业务，由于其业务种类千差万别，对网络需求存在很大差异。大致来说，会存在如下几种需求：
可靠传输，但对时延不敏感；
低延迟，高可靠传输。
对可靠传输，而对时延不敏感业务，较容易处理。但是，对低延迟、高可靠传输类的业务，不仅要求传输时延短，而且要求可靠，比如V2V(英文全称为：Vehicle to Vehicle)业务。如果传输不可靠，会导致重传而造成传输时延过大，不能满足要求。
由于大量连接的存在，使得未来的无线通信系统和现有的通信系统存在很大差异。大量连接需要消耗更多的资源接入终端设备以及需要消耗更多的资源用于终端设备的数据传输相关的调度信令的传输。根据本发明实施例的方案能够有效解决上述资源消耗问题。
可选地，该网络设备为基站，该终端设备为用户设备。
本发明结合终端设备(例如，第一终端设备和第二终端设备)描述了各 个实施例。终端设备也可以称为用户设备(UE，User Equipment)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备可以是无线局域网(Wireless Local Area Networks，WLAN)中的站点(STAION，ST)，可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及未来5G网络中的终端设备或者未来演进的PLMN网络中的终端设备等。
此外，本发明结合网络设备(例如，第一网络设备)描述了各个实施例。网络设备可以是网络设备等用于与移动设备通信的设备，网络设备可以是WLAN中的接入点(ACCESS POINT，AP)，GSM或码分多址(Code Division Multiple Access，CDMA)中的基站(Base Transceiver Station，BTS)，也可以是WCDMA中的基站(NodeB，NB)，还可以是长期演进(Long Term Evolution，LTE)中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者中继站或接入点，或者车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等。
另外，在本发明实施例中，网络设备(例如基站)可以是宏基站，也可以是用于提供小小区(small cell)的基站，这里的小小区可以包括：城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。
本发明实施例提供的无线通信的方法和装置，可以应用于终端设备或网络设备，该终端设备或网络设备包括硬件层、运行在硬件层之上的操作系统层，以及运行在操作系统层上的应用层。该硬件层包括中央处理器(Central Processing Unit，CPU)、内存管理单元(MMU，Memory Management Unit)和内存(也称为主存)等硬件。该操作系统可以是任意一种或多种通过进程(Process)实现业务处理的计算机操作系统，例如，Linux操作系统、Unix操作系统、Android操作系统、iOS操作系统或windows操作系统等。该应用层包含浏览器、通讯录、文字处理软件、即时通信软件等应用。并且，在本发明实施例中，无线通信的方法的执行主体的具体结构，本发明并未特别 限定，只要能够通过运行记录有本发明实施例的无线通信的方法的代码的程序，以根据本发明实施例的无线通信的方法进行通信即可，例如，本发明实施例的无线通信的方法的执行主体可以是终端设备或网络设备，或者，是终端设备或网络设备中能够调用程序并执行程序的功能模块。
此外，本发明的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如，计算机可读介质可以包括，但不限于:磁存储器件(例如，硬盘、软盘或磁带等)，光盘(例如，压缩盘(Compact Disc，CD)、数字通用盘(Digital Versatile Disc，DVD)等)，智能卡和闪存器件(例如，可擦写可编程只读存储器(Erasable Programmable Read-Only Memory，EPROM)、卡、棒或钥匙驱动器等)。另外，本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
图1是使用本发明的通信系统的一例的示意图。如图1所示，在本法实施例中，通信系统包括接入网络100和接入网络200，其中，接入网络100包括网络设备102和至少一个终端设备116，接入网络200包括网络设备202和至少一个终端设备216，其中，网络设备102与网络设备202可以通过例如，光线等传输介质通信连接，从而，终端设备116能够在需要与终端设备216通信时，可以通过接入网络100提供的无线资源(例如，时域资源、频域资源、空域资源和码域资源等)将数据发送给网络设备102，网络设备102可以通过与网络设备202之间的通信连接，将该数据发送至网络设备202，从而，网络设备202可以通过接入网络200提供的无线资源将数据发送给终端设备216。
应理解，图1示出的通信系统的结构仅为示例性说明，本发明并未限定于此，例如，通信系统还可以包括例如核心网设备和网关设备等，再例如，该通信系统包括的接入网络的数量以及各接入网络中的网络设备和终端设备的数量可以根据需要任意变更，本发明并未特别限定。
在本发明实施例中，该通信系统可以是公共陆地移动网络(英文全称可以为：Public Land Mobile Network，英文简称可以为：PLMN)网络或者D2D网络或者M2M网络或者其他网络，图1只是举例的简化示意图，网络中还 可以包括其他网络设备，图1中未予以画出。
下面结合图2对接入网络的具体结构进行详细说明，其中，网络设备102和终端设备116之间的通信方式与网络设备202和终端设备216之间的通信方式相似，这里，为了避免赘述，以网络设备102和终端设备116之间的通信方式为例，对接入网络的结构和工作方式进行详细说明。

网络设备102可以与多个终端设备(例如终端设备116和终端设备122)通信。然而，可以理解，网络设备102可以与类似于终端设备116或122的任意数目的终端设备通信。终端设备116和122可以是例如蜂窝电话、智能电话、便携式电脑、手持通信设备、手持计算设备、卫星无线电装置、全球定位系统、PDA和/或用于在无线通信系统100上通信的任意其它适合设备。
如图1所示，终端设备116与天线112和114通信，其中天线112和114通过前向链路118向终端设备116发送信息，并通过反向链路120从终端设备116接收信息。此外，终端设备122与天线104和106通信，其中天线104和106通过前向链路124向终端设备122发送信息，并通过反向链路126从终端设备122接收信息。
例如，在频分双工(FDD，Frequency Division Duplex)系统中，例如，前向链路118可与反向链路120使用不同的频带，前向链路124可与反向链路126使用不同的频带。
再例如，在时分双工(TDD，Time Division Duplex)系统和全双工(Full Duplex)系统中，前向链路118和反向链路120可使用共同频带，前向链路124和反向链路126可使用共同频带。
被设计用于通信的每个天线(或者由多个天线组成的天线组)和/或区域称为网络设备102的扇区。例如，可将天线组设计为与网络设备102覆盖区域的扇区中的终端设备通信。在网络设备102通过前向链路118和124分别与终端设备116和122进行通信的过程中，网络设备102的发射天线可利用波束成形来改善前向链路118和124的信噪比。此外，与网络设备通过单个 天线向它所有的终端设备发送信号的方式相比，在网络设备102利用波束成形向相关覆盖区域中随机分散的终端设备116和122发送信号时，相邻小区中的移动设备会受到较少的干扰。
在给定时间，网络设备102、终端设备116或终端设备122可以是无线通信发送装置和/或无线通信接收装置。当发送数据时，无线通信发送装置可对数据进行编码以用于传输。具体地，无线通信发送装置可获取(例如生成、从其它通信装置接收、或在存储器中保存等)要通过信道发送至无线通信接收装置的一定数目的数据比特。这种数据比特可包含在数据的传输块(或多个传输块)中，传输块可被分段以产生多个码块。
可选地，该第一终端设备与该第二终端设备进行无线通信时传输的数据为声音数据或图像数据。
具体地说，作为示例而非限定，本发明实施例的无线通信的方法可以应用于例如，基于例如VoIP(Voice over Internet Protocol)或VoLTE(Voice over LTE)等技术传输声音数据的场景。
VoIP简而言之就是将模拟信号(Voice)数字化，以数据封包(Data Packet)的形式在网际协议(Internet Protoco，IP)网络(Network)上做实时传递。VoIP最大的优势是能广泛地采用股联网(Internet)和全球IP互连的环境，提供比传统业务更多、更好的服务。VoIP可以在IP网络上便宜的传送语音、传真、视频、和数据等业务，如统一消息业务、虚拟电话、虚拟语音/传真邮箱、查号业务、Internet呼叫中心、Internet呼叫管理、电话视频会议、电子商务、传真存储转发和各种信息的存储转发等。
VoLTE是基于IP多媒体子系统(IMS，IP Multimedia Subsystem)网络承载语音业务，可实现数据与语音业务在同一网络下的统一。换言之，4G网络下不仅仅提供高速率的数据业务，同时还提供高质量的音视频通话，后者便需要VoLTE技术来实现。
基于新的网络和新的要求，无论是从节省传输频带资源，还是保持线路通信的高效率等方面来看，研究采用各种可变速率语音编码技术的系统都有重要意义。目前为了适应此需要提出了自适应多速率(Adaptive Multi-rate，AMR)的概念，即自适应多速率语音编码器，主要用于移动设备的音频，压缩比比较大，但相对其他的压缩格式质量比较差，由于多用于人声通话。AMR又分为两种，一种是自适应多速率窄带编码(AMR-NarrowBind，AMR －NB)，语音带宽范围：300－3700Hz，8KHz采样频率；另外一种是自适应多速率宽带编码(AMR WideBand，AMR-WB)，语音带宽范围50－7000Hz，16KHz采样频率。但考虑语音的短时相关性，每帧长度均为20ms。这两种编码器根据带宽的要求虽然选用了不同的速率，但有异曲同工之处。
在AMR－NB中，AMR的采样频率为8KHz，每20ms编码一帧，每个帧中包含160个语音样点。
AMR采用的是基于代数码激励线性预测(ACELP)的编码模式，编码端提取ACELP模型参数(线性预测系数，自适应码本和固定码本索引及增益)，解码端接收到数据然后根据这些参数从新合成语音。
TD-SCDMA中AMR-NB的实现。此编码器运用了代数码本线性预测(ACELP)混合编码方式，也就是数字语音信号中既包括若干语音特征参数又包括部分波形编码信息，再运用这些特征信息重新合成语音信号的过程。
控制这些参数的提取数目，根据速率要求对信息进行取舍而得到了以下8种速率，混合组成如下表a所示的自适应语音编码器。如模式AMR_12.20就提取出244比特的参数信息，而模式AMR_4.70却只提取了95比特信息。根据这些比特所含的信息量可以将其分为3类比特class 0，1和2。在信道编码时class 0和1都将会使用循环冗余校验码进行差错检验，对于class 2则根据上一帧进行恢复。

在AMR-WB中采样频率为16kHz，是一种同时被国际标准化组织ITU-T和3GPP采用的宽带语音编码标准，也称为G722.2标准。并且，在AMR-WB 中，支持9种不同的编码方式(或者说，编码模型)，该9种编码方式对应的编码器比特速率分别为：6.6kb/s、8.85kb/s、12.65kb/s、14.25kb/s、15.85kb/s、18.25kb/s、19.85kb/s、23.05kb/s和23.85kb/s。提供的语音带宽范围达到50～7000Hz，人声感觉比以前更加自然、舒适和易于分辨。
即，在本发明实施例中，码率(例如，包括第一码率)可以是指编码器的比特率(或者说，比特速率)，比特率是指每秒传送的比特(bit)数。单位为bps(Bit Per Second)，比特率越高，传送的数据越大。比特率表示经过编码(压缩)后的音视频数据每秒钟需要用多少个比特来表示。
作为示例而非限定，在本发明实施例中，比特率与音视频压缩可以具有以下关系：比特率越高，音视频的质量就越好，但编码后的文件就越大；如果比特率越低则音视频的质量就越低，但编码后的文件就越小。
下面，结合图3和图4，对本发明实施例的无线通信的具体过程进行详细说明。
图3是本发明实施例的无线通信的方法300的一例的示意性交互图。
如图3所示，在终端设备#A(即，第一终端设备的一例)与终端设备#B(即，第二终端设备)进行无线通信(例如，传输语音数据)时。终端设备#A可以采用某种码率#A对需要发送的数据进行编码处理(或者，也可以称为压缩处理)，并将得到的数据发送给该终端设备#A所接入的网络设备#A，网络设备#A将该数据发送给该终端设备#B所接入的网络设备#B，从而，网络设备#B可以将该数据发送给终端设备#B。
其中，该码率#A可以是系统规定的码率，也可以是网络设备#A通过信令指示给终端设备#A的码率，或者，该码率A还可以是终端设备#A和终端设备#B(例如，经由网络设备#A和网络设备#B)协商确定的码率。
在本发明实施例中，将终端设备#A能够适用的(例如，终端设备#A能够支持的，或，网络设备指定终端设备#A使用的)一个或多个码率称为码率集合#A，将终端设备#B能够适用的(例如，终端设备#B能够支持的，或，网络设备指定终端设备#B使用的)一个或多个码率称为码率集合#B，则上述码率#A可以属于码率集合#A，且码率#A可以属于码率集合#A。
即，终端设备#A和终端设备#B均能够支持该码率#A，从而，能够确保终端设备#A能够基于码率#A完成对数据的编码，并确保终端设备#B能够基于码率#A完成对数据的解码。
在本发明实施例中，终端设备#A与网络设备#A之间的链路#A(即，第一链路的一例)的质量可能动态变化，因此，在本发明实施例中，可以引入链路质量上报机制，即，终端设备#A可以例如，周期性地检测链路#A的质量，并且上报至网络设备#A，从而，网络设备#A能够基于链路#A的质量，对码率#A进行调整，以使调整后的码率能够确保在终端设备#A上报的链路#A的质量下的通信的准确性。
下面，对本发明实施例中的链路质量上报机制进行详细说明。
在本发明实施例中，终端设备#A判定是否上报链路质量时可以使用两种参数，即：链路#A的质量和码率#B(即，第一码率的一例)。
其中，码率#B可以是一个，也可以是多个，本发明并未特别限定。
可选地，该第一码率是该第一终端设备能够适用的最大码率与该第二终端设备能够适用的最大码率中较小的一方，或
该第一码率是该第一终端设备能够适用的码率的集合与第二终端设备能够适用的码率的集合的交集，或
该第一码率是该第一终端设备能够适用的最大码率，或
该第一码率是该第一终端设备能够适用的码率的集合，或
该第一码率是该第二终端设备能够适用的最大码率，或
该第一码率是该第二终端设备能够适用的码率的集合。
具体地说，该码率#B可以是根据该终端设备#A能够适用的(例如，终端设备#A能够支持的，或，网络设备指定终端设备#A使用的)一个或多个码率(例如，上述码率集合#A)确定的，例如，该码率#B可以是码率集合#A中的部分或全部码率。并且，此情况下，作为示例而非限定，高层(例如，应用层或IMS层)可以指示终端设备#A该码率集合#A。
或者，该码率#B可以是根据该终端设备#B能够适用的(例如，终端设备#B能够支持的，或，网络设备指定终端设备#B使用的)一个或多个码率(例如，上述码率集合#B)确定的，例如，该码率#B可以是码率集合#B中的部分或全部码率。
需要说明的是，此情况下，例如，终端设备#B可以经由网络设备#B和网络设备A向终端设备#A发送该码率集合#B的指示信息，再例如，运营商、网络管理员可以获知码率集合#B，并将码率集合#B的指示信息下发至终端设备#A，以便于终端设备#A获知码率集合#B。或者，高层(例如，应用层 或IMS层)可以指示终端设备#A该码率集合#B。
再或者，该码率#B可以是根据该码率集合#A以及码率集合#B确定的，如，码率#B可以是即属于码率集合#A又属于码率集合#B的码率。
再或者，终端设备#A可以将码率集合#A和码率集合#B的交集中最大的码率作为码率#B。
再或者，终端设备#A可以将码率集合#A和码率集合#B的交集中的部分或全部码率作为码率#B。
作为示例而非限定，上述码率#B由高层(例如应用层或者IMS层)建议的编解码集合和/或接入层建议的编解码集合确定。其中高层(例如应用层或者IMS层)建议的编解码集合可以进一步的包括对端终端可以通信的编解码集合。
需要说明的是，在本发明实施例中，该终端设备#A可以将该码率#B直接作为待比较的判定参数，作为示例而非限定，此情况下，比较的对象可以是该码率#B与建议码率，即方式1，随后，对该方式1的具体处理过程进行详细说明。
或者，该终端设备#A也可以基于码率#B确定该码率#B对应的参考质量范围，并将该参考质量范围作为待比较的判定参数，作为示例而非限定，此情况下，比较的对象可以是该链路#A的质量与该参考质量范围，即，方式2，随后，对该方式2的具体处理过程进行详细说明。
在本发明实施例中，该参考质量范围可以是指在满足通信的可靠性和准确性的前提下，码率#B能够适用于的质量的范围。
以下，为了便于理解和说明，将该参考质量范围中的最大值记做：参考质量ThmaxA(即，第一参考质量的一例)，将该质量阈值范围中的最小值记做：参考质量ThmaxB(即，第二参考质量的一例)。
需要说明的是，上述参考质量范围可以包括多个值，此情况下，参考质量ThmaxA和参考质量ThmaxB不同；或者，上述参考质量范围可以包括一个值，此情况下，参考质量ThmaxA和参考质量ThmaxB相同，本发明并未特别限定。
从而，在S310，终端设备#A可以测量链路#A的质量。需要说明的是，终端设备#A可以测量链路#A的质量的方法和过程，可以与现有技术相似，这里，为了避免赘述，省略其详细说明。
在S320，终端设备#A可以根据链路#A的质量和码率#B，确定针对链路#A的质量的上报策略，即是否上报链路#A的质量。
方式1
可选地，该第一终端设备根据该第一链路的链路质量和第一码率，进行针对该第一链路的链路质量的上报处理，包括：
该第一终端设备根据第一关系和第二关系，进行针对该第一链路的链路质量的上报处理，其中，该第一关系是该第一链路的链路质量与预设的第一质量阈值之间的大小关系，该第二关系是该第一码率与建议码率之间的大小关系，该建议码率是该第一网络设备在当前时刻之前最近一次指示该第一终端设备使用的码率。
具体地说，作为示例而非限定，在本发明实施例中，终端设备#A可以基于链路#A的质量与预设的质量阈值范围(例如，包括第一质量阈值和第二质量阈值)的比较结果(即，第一关系一例)，以及码率#B和建议码率的比较结果(即，第二关系的一例)，确定上报策略。
其中，该建议码率是在终端设备#A和终端设备#B的通信期间，网络设备A最近一次(即，当前时刻之前最后一次)指示终端设备#A使用的码率。
应理解，建议码率是可以是终端设备#A当前使用的码率(例如，上述码率#A)，也可以不是终端设备#A当前使用的码率，本发明并未特别限定。
在本发明实施例中，该质量范围可以是指在满足通信的可靠性和准确性的前提下，当前使用的码率(例如，码率#A)能够适用于的质量的范围。
以下，为了便于理解和说明，将该质量阈值范围中的最大值记做：质量阈值ThA(即，第一质量阈值的一例)，将该质量阈值范围中的最小值记做：质量阈值ThB(即，第二质量阈值的一例)。
需要说明的是，上述质量阈值范围可以包括多个值，此情况下，质量阈值ThA和质量阈值ThB不同；或者，上述质量阈值范围可以包括一个值，此情况下，质量阈值ThA和质量阈值ThB相同，本发明并未特别限定。
在本发明实施例中，该质量阈值范围可以是网络设备#A确定并下发给终端设备#A的。即：
可选地，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该第一质量阈值的指示信息。
可选地，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该第二质量阈值的指示信息和该参考质量的指示信息。
另外，在本发明实施例中，该质量阈值范围可以是网络设备#A或终端设备#A根据码率#A确定的。
例如，可以在终端设备#A或网络设备#A中保存多种码率与多种质量范围之间的一一映射关系，从而，终端设备#A或网络设备#A可以基于当前使用的码率(例如，码率#A)从该映射关系中确定与码率#A对应的质量范围，作为当前用于判定上报策略时所使用的质量范围。即：
可选地，该第一质量阈值是根据该建议码率确定的。
或者，可选地，该第二质量阈值是根据该建议码率确定的。
下面，对链路#A的质量与该质量阈值范围(例如，质量阈值范围中的最大值，即，第一质量阈值)的比较结果，以及码率#B和建议码率的比较结果的情况与所确定上报策略之间的关系进行示例性说明。
情况1
该第一终端设备根据第一关系和第二关系，进行针对该第一链路的链路质量的上报处理，包括：
如果该第一关系为该第一链路的链路质量大于或等于该第一质量阈值，且该第二关系为第一码率小于该建议码率，则该第一终端设备不向该第一网络设备上报该第一链路的链路质量。
具体地说，如果链路#A的质量高于(或者说，大于或等于)质量阈值ThA，且码率#B小于建议码率，则终端设备#A可以确定上报策略为：不向网络设备#A上报链路#A的质量。
由于链路#A的质量高于质量阈值ThA，因此如果终端设备#A向网络设备#A上报链路#A的质量，则网络设备#A会判定为需要以增大当前码率的方式进行调整，则可能导致网络设备#A确定的需要调整至的码率(记做：目标码率)大于建议码率。
并且，由于码率#B小于建议码率，则导致码率#B小于目标码率，如上所述该码率#B是终端设备#A和/或终端设备#B适用的码率，则意味着终端设备#A和/或终端设备#B无法支持目标码率。
如果按照现有技术，终端设备#A仍然向网络设备#A上报链路#A的质 量的话，会造成本次调节无法得到预期效果，调节过程失败，造成了通信资源和处理资源的浪费。
与此相对，在本发明实施例中，当终端设备#A确定链路#A的质量高于质量阈值ThA，且码率#B小于建议码率时，终端设备#A不向网络设备#A上报链路#A的质量，能够避免上报过程的通信资源和处理资源的浪费。
情况2
该第一终端设备根据第一关系和第二关系，进行针对该第一链路的链路质量的上报处理，包括：
如果该第一关系为该第一链路的链路质量大于或等于该第一质量阈值，且该第二关系为第一码率大于或等于该建议码率，则该第一终端设备向该第一网络设备上报该第一链路的链路质量
具体地说，由于链路#A的质量高于质量阈值ThA，因此如果终端设备#A向网络设备#A上报链路#A的质量，则网络设备#A会判定为需要以增大当前码率的方式进行调整，则可能导致网络设备#A确定的需要调整至的码率(记做：目标码率)大于建议码率。
并且，由于码率#B大于或等于建议码率，则导致码率#B可能大于或等于目标码率，如上所述该码率#B是终端设备#A和/或终端设备#B适用的码率，则意味着终端设备#A和/或终端设备#B可能支持目标码率。
根据本发明实施例，此情况下，终端设备#A可以向网络设备#A上报链路#A的质量。
再例如，作为示例而非限定，在本发明实施例中，终端设备#A可以基于链路#A的质量与预设的质量阈值范围(例如，包括第一质量阈值和第二质量阈值)的比较结果(即，第三关系一例)，以及链路#A的质量和上述参考质量范围的比较结果(即，第四关系的一例)确定上报策略。即：
可选地，该第一终端设备根据该第一链路的链路质量和第一码率，进行针对该第一链路的链路质量的上报处理，包括：
该第一终端设备根据第三关系和第四关系，进行针对该第一链路的链路质量的上报处理，其中，该第三关系是该第一链路的链路质量与预设的第二质量阈值之间的大小关系，该第四关系是该第一链路的链路质量与参考质量之间的大小关系，该参考质量是根据该第一码率确定的。
即，在本发明实施例中，可以如以下表1所述确定上报策略。

方式2
可选地，该第一终端设备根据该第一链路的链路质量和第一码率，进行针对该第一链路的链路质量的上报处理，包括：
该第一终端设备根据第三关系和第四关系，进行针对该第一链路的链路质量的上报处理，其中，该第三关系是该第一链路的链路质量与预设的第二质量阈值之间的大小关系，该第四关系是该第一链路的链路质量与参考质量之间的大小关系，该参考质量是根据该第一码率确定的。
具体地说，作为示例而非限定，在本发明实施例中，终端设备#A可以基于链路#A的质量与预设的质量阈值范围(例如，包括第一质量阈值和第二质量阈值)的比较结果(即，第三关系一例)，以及链路#A的质量与上述参考质量范围(例如，包括第一参考质量和第二参考质量)的比较结果(即，第四关系一例)，确定上报策略。
下面，对链路#A的质量与该质量阈值范围(例如，质量阈值范围中的最小值，即，第二质量阈值)的比较结果，以及链路#A的质量和上述参考质量范围的比较结果的情况与所确定上报策略之间的关系进行示例性说明。
情况3
该第一终端设备根据第三关系和第四关系，进行针对该第一链路的链路质量的上报处理，包括：
如果该第三关系为该第一链路的链路质量小于或等于该第二质量阈值，且该第四关系为该第一链路的链路质量大于或等于第一参考质量，则该第一终端设备不向该第一网络设备上报该第一链路的链路质量。
具体地说，如果链路#A的质量低于(或者说，小于或等于)质量阈值ThB，且链路#A的质量大于或等于参考质量ThmaxA，则终端设备#A可以确定上报策略为：不向网络设备#A上报链路#A的质量。
由于链路#A的质量低于质量阈值ThB，因此如果终端设备#A向网络设 备#A上报链路#A的质量，则网络设备#A会判定为需要以减小当前码率的方式进行调整。并且，由于且链路#A的质量大于或等于参考质量ThmaxA，表示码率#B不适用于链路#A的质量，即，当前使用的码率(例如，码率#A)大于码率#B。因此，可能出现即使以减小当前码率的方式进行调整，但是如果调整幅度较小，仍然使调整后的码率高于码率#B。
如果按照现有技术，终端设备#A仍然向网络设备#A上报链路#A的质量的话则可能导致网络设备#A确定的需要调整至的码率(记做：目标码率)大于码率#B，如上所述该码率#B是终端设备#A和/或终端设备#B适用的码率，则意味着终端设备#A和/或终端设备#B无法支持目标码率，会造成本次调节无法得到预期效果，调节过程失败，造成了通信资源和处理资源的浪费。
与此相对，在本发明实施例中，当终端设备#A确定链路#A的质量低于质量阈值ThB，且链路#A的质量大于或等于参考质量ThmaxA时，终端设备#A不向网络设备#A上报链路#A的质量，能够避免上报过程的通信资源和处理资源的浪费。
情况4
该第一终端设备根据第三关系和第四关系，进行针对该第一链路的链路质量的上报处理，包括：
如果该第三关系为该第一链路的链路质量小于或等于该第二质量阈值，且该第四关系为该第一链路的链路质量小于第二参考质量，则该第一终端设备向该第一网络设备上报该第一链路的链路质量
具体地说，由于链路#A的质量低于质量阈值ThB，因此如果终端设备#A向网络设备#A上报链路#A的质量，则网络设备#A会判定为需要以减小当前码率的方式进行调整。
并且，由于且链路#A的质量小于参考质量ThmaxB，表示码率#B适用于链路#A的质量，即，当前使用的码率(例如，码率#A)小于码率#B。
因此，以减小当前码率的方式进行调整，能够使调整后的码率低于码率#B。如上所述该码率#B是终端设备#A和/或终端设备#B适用的码率，则意味着终端设备#A和/或终端设备#B可能支持调整后的码率。
根据本发明实施例，此情况下，终端设备#A可以向网络设备#A上报链路#A的质量。
即，在本发明实施例中，可以如以下表2所述确定上报策略。
表2

在S330，网络设备#A可以基于终端设备#A上报的链路#A的质量，进行针对该终端设备#A所使用的码率的调整处理，其中，该调整处理的过程和方法可以与现有技术相似，这里，为了避免赘述，省略其详细说明。
根据本发明实施例的无线通信的方法，通过使终端设备在测量链路的质量后，判定链路的质量和第一码率是否满足预设的条件，并根据该判定结果确定是否上报链路的质量，由于上述预设条件是基于终端设备或对端所能够适用的码率确定的，能够确保在上报链路的质量后，网络设备基于该链路的质量确定的调整后的码率得到终端设备或对端的支持，从而能够支持降低上报链路质量的通信资源开销，减少终端设备和网络设备的处理负担。
可选地，该方法还包括：
该第一终端设备向该第一网络设备发送该第一码率的指示信息。
具体地说，在本发明实施例中，在终端设备#A向网络设备#A上报链路#A的质量时，可以将上述码率#B的指示信息一并上报至网络设备#A从而，网络设备#B可以基于该链路#A的质量，确定终端设备#A当前使用的码率所需要调整至的目标码率，并且，该确定目标码率的方法和过程可以与现有技术相似，这里为了避免赘述，省略其详细说明。其后，网络设备#B可以基于目标码率和码率#B的大小关系，确定是否向终端设备#A下发目标码率。
作为示例而非限定，例如，如果目标码率大于码率#B，如上所述该码率#B是终端设备#A和/或终端设备#B适用的码率，则意味着终端设备#A和/或终端设备#B无法支持目标码率，此时，网络设备#B可以不向终端设备#A下发目标码率。
再例如，如果目标码率小于码率#B，如上所述该码率#B是终端设备#A和/或终端设备#B适用的码率，则意味着终端设备#A和/或终端设备#B可能支持目标码率，此时，网络设备#B可以向终端设备#A下发目标码率。
根据本发明实施例的无线通信的方法，通过使终端设备在测量链路的质 量后，将链路的质量和第一码率一并上报至网络设备，由于上述预设条件是基于终端设备或对端所能够适用的码率确定的，能够确保在上报链路的质量后，网络设备基于该链路的质量确定的调整后的码率得到终端设备或对端的支持，从而能够支持降低上报链路质量的通信资源开销，减少终端设备和网络设备的处理负担。
图4是本发明实施例的无线通信的方法的另一例的示意性交互图。如图4所示，在终端设备#A(即，第一终端设备的一例)与终端设备#B(即，第二终端设备)进行无线通信(例如，传输语音数据)时。终端设备#A可以采用某种码率#A对需要发送的数据进行编码处理(或者，也可以称为压缩处理)，并将得到的数据发送给该终端设备#A所接入的网络设备#A，网络设备#A将该数据发送给该终端设备#B所接入的网络设备#B，从而，网络设备#B可以将该数据发送给终端设备#B，其中，该码率#A可以是系统规定的码率，也可以是网络设备#A通过信令指示给终端设备#A的码率，或者，该码率A还可以是终端设备#A和终端设备#B(例如，经由网络设备#A和网络设备#B)协商确定的码率。
在本发明实施例中，将终端设备#A能够适用的一个或多个码率称为码率集合#A，将终端设备#B能够适用的一个或多个码率称为码率集合#B，则上述码率#A可以属于码率集合#A，且码率#A可以属于码率集合#A。即，终端设备#A和终端设备#B均能够支持该码率#A，从而，能够确保终端设备#A能够基于码率#A完成对数据的编码，并确保终端设备#B能够基于码率#A完成对数据的解码。
在本发明实施例中，终端设备#A与网络设备#A之间的链路#A(即，第一链路的一例)的质量可能动态变化，因此，在本发明实施例中，可以引入链路质量上报机制，即，终端设备#A可以例如，周期性地检测链路#A的质量，并且上报至网络设备#A，从而，网络设备#A能够基于链路#A的质量，对码率#A进行调整，以使调整后的码率能够确保在终端设备#A上报的链路#A的质量下的通信的准确性。
从而，在S410，终端设备#A可以测量链路#A的质量。需要说明的是，终端设备#A可以测量链路#A的质量的方法和过程，可以与现有技术相似，这里，为了避免赘述，省略其详细说明。
在S420，终端设备#A在向网络设备#A上报链路质量时可以一并上报码 率#B(即，第一码率的一例)。
其中，码率#B可以是一个，也可以是多个，本发明并未特别限定。
可选地，该第一码率是该第一终端设备能够适用的最大码率与该第二终端设备能够适用的最大码率中较小的一方，或
该第一码率是第一终端设备能够适用的码率的集合与第二终端设备能够适用的码率的集合的交集，或
该第一码率是该第一终端设备能够适用的最大码率，或
该第一码率是该第一终端设备能够适用的码率的集合，或
该第一码率是该第二终端设备能够适用的最大码率，或
该第一码率是该第二终端设备能够适用的码率的集合。
具体地说，该码率#B可以是根据该终端设备#A能够适用的一个或多个码率(例如，上述码率集合#A)确定的，例如，该码率#B可以是码率集合#A中的部分或全部码率。并且，此情况下，作为示例而非限定，高层(例如，应用层或IMS层)可以指示终端设备#A该码率集合#A。
或者，该码率#B可以是根据该终端设备#B能够适用的一个或多个码率(例如，上述码率集合#B)确定的，例如，该码率#B可以是码率集合#B中的部分或全部码率。需要说明的是，此情况下，例如，终端设备#B可以经由网络设备#B和网络设备A向终端设备#A发送该码率集合#B的指示信息，再例如，运营商、网络管理员可以获知码率集合#B，并将码率集合#B的指示信息下发至终端设备#A，以便于终端设备#A获知码率集合#B。或者，高层(例如，应用层或IMS层)可以指示终端设备#A该码率集合#B。
再或者，该码率#B可以是根据该码率集合#A以及码率集合#B确定的，如，码率#B可以是即属于码率集合#A又属于码率集合#B的码率。
再或者，终端设备#A可以将码率集合#A和码率集合#B的交集中最大的码率作为码率#B。
再或者，终端设备#A可以将码率集合#A和码率集合#B的交集中的部分或全部码率作为码率#B。
作为示例而非限定，上述码率#B由高层(例如应用层或者IMS层)建议的编解码集合和/或接入层建议的编解码集合确定。其中高层(例如应用层或者IMS层)建议的编解码集合可以进一步的包括对端终端可以通信的编解码集合。
从而，在S430，网络设备#B可以基于该链路#A的质量，确定终端设备#A当前使用的码率所需要调整至的目标码率，并且，该确定目标码率的方法和过程可以与现有技术相似，这里为了避免赘述，省略其详细说明。
其后，网络设备#B可以基于目标码率和码率#B的大小关系，确定是否向终端设备#A下发目标码率。
例如，可选地，该第一网络设备根据该目标码率和该第一码率之间的大小关系，进行针对该第一终端设备当前使用的码率的调整处理，包括：
如果该第一码率小于或等于该目标码率，则该第一网络设备不调整该第一终端设备当前使用的码率。
具体地说，如果目标码率大于码率#B，如上所述该码率#B是终端设备#A和/或终端设备#B适用的码率，则意味着终端设备#A和/或终端设备#B无法支持目标码率，此时，网络设备#B可以不向终端设备#A下发目标码率。
再例如，可选地，该第一网络设备根据该目标码率和该第一码率之间的大小关系，进行针对该第一终端设备当前使用的码率的调整处理，包括：
如果该第一码率大于该目标码率，则该第一网络设备将该第一终端设备当前使用的码率调整为该目标码率
具体地说，如果目标码率小于码率#B，如上所述该码率#B是终端设备#A和/或终端设备#B适用的码率，则意味着终端设备#A和/或终端设备#B可能支持目标码率，此时，网络设备#B可以向终端设备#A下发目标码率。
另外，在本发明实施例中，在终端设备#A向网络设备#A上报链路#A的质量和码率#B之前，还可以进行判定，即判定是否需要质量链路#A的质量和码率#B。
在本发明实施例中，终端设备#A判定是否上报链路质量时可以使用链路#A的质量作为判定参数。
具体地说，作为示例而非限定，在本发明实施例中，终端设备#A可以基于链路#A的质量与预设的质量阈值范围(例如，包括第一质量阈值和第二质量阈值)的比较结果，确定上报策略(即，是否上报链路#A的质量和码率#B)。
以下，为了便于理解和说明，将该质量阈值范围中的最大值记做：质量阈值ThA(即，第一质量阈值的一例)，将该质量阈值范围中的最小值记做：质量阈值ThB(即，第二质量阈值的一例)。
需要说明的是，上述质量阈值范围可以包括多个值，此情况下，质量阈值ThA和质量阈值ThB不同；或者，上述质量阈值范围可以包括一个值，此情况下，质量阈值ThA和质量阈值ThB相同，本发明并未特别限定。
在本发明实施例中，该质量阈值范围可以是网络设备#A确定并下发给终端设备#A的。即：
可选地，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该第一质量阈值的指示信息。
可选地，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该第二质量阈值的指示信息和该参考质量的指示信息。
另外，在本发明实施例中，该质量阈值范围可以是网络设备#A或终端设备#A根据码率#A确定的。
例如，可以在终端设备#A或网络设备#A中保存多种码率与多种质量范围之间的一一映射关系，从而，终端设备#A或网络设备#A可以基于当前使用的码率(例如，码率#A)从该映射关系中确定与码率#A对应的质量范围，作为当前用于判定上报策略时所使用的质量范围。即：
可选地，该第一质量阈值是根据该建议码率确定的。
或者，可选地，该第二质量阈值是根据该建议码率确定的。
下面，对链路#A的质量与该质量阈值范围(例如，质量阈值范围中的最大值，即，第一质量阈值)的比较结果与所确定上报策略之间的关系进行示例性说明。
例如，可选地，该第一终端设备向该第一网络设备发送该第一链路的链路质量的指示信息以及第一码率的指示信息，包括：
该第一终端设备在确定该第一链路的链路质量大于或等于预设的第一质量阈值后，向该第一网络设备发送该第一链路的链路质量的指示信息以及第一码率的指示信息。
具体地说，如果链路#A的质量高于(或者说，大于或等于)质量阈值ThA，则终端设备#A可以确定上报策略为：向网络设备#A上报链路#A的质量。
即，由于质量阈值ThA是当前使用的码率(例如，码率#A)所使用的 质量上限，如果链路#A的质量高于质量阈值ThA，则表示当前的链路质量可以适用于更高的码率。从而网络设备#A可能会基于该链路#A的质量和码率#B，对终端设备#A当前使用的码率进行调整。
相反，如果链路#A的质量低于(小于或等于)质量阈值ThA，则表示当前的链路质量不可以适用于更高的码率。从而网络设备#A可能不会对终端设备#A当前使用的码率进行调整。
再例如，可选地，该第一终端设备向该第一网络设备发送该第一链路的链路质量的指示信息以及第一码率的指示信息，包括：
该第一终端设备在确定该第一链路的链路质量小于或等于预设的第二质量阈值后，向该第一网络设备发送该第一链路的链路质量的指示信息以及第一码率的指示信息。
具体地说，如果链路#A的质量低于(或者说，小于)质量阈值ThB，则终端设备#A可以确定上报策略为：向网络设备#A上报链路#A的质量。
即，由于质量阈值ThB是当前使用的码率(例如，码率#A)所使用的质量下限，如果链路#A的质量低于质量阈值ThA，则表示当前的链路质量下无法使用码率#A。从而网络设备#A可能会基于该链路#A的质量和码率#B，对终端设备#A当前使用的码率进行调整。
相反，如果链路#A的质量高于(大于或等于)质量阈值ThB，则表示当前的链路质量可以适用于码率#A。从而网络设备#A可能不会对终端设备#A当前使用的码率进行调整。
根据本发明实施例的无线通信的方法，通过使终端设备在测量链路的质量后，将链路的质量和第一码率一并上报至网络设备，由于第一码率是基于终端设备或对端所能够适用的码率确定的，能够确保在上报链路的质量后，网络设备基于该链路的质量确定的调整后的码率得到终端设备或对端的支持，从而能够支持降低上报链路质量的通信资源开销，减少终端设备和网络设备的处理负担。
