Description
本发明涉及无线通信技术领域,具体涉及一种语音自适应参数的调整方法、系统及相关设备。
移动带宽语音在无线接入网设备从全球移动通信系统(Global System for Mobile communication,简称GSM)/码分多址接入系统(Code Division Multiple Access,简称CDMA)/通用移动通信系统(Universal Mobile Telecommunications System,简称UMTS)等向LTE演进,其中,曾出现多种用于解决LTE语音的方案,最为常用却发展最为快速的是基于互联网协议多媒体子系统(Internet Protocol Multimedia subsystem,简称IMS)的LTE网络语音(Voice over LTE,简称VoLTE),成为全互联网协议(Internet Protocol,简称IP)时代的核心网标准架构。从长远来看,VoLTE能够带来三方面价值:一是提升无线频谱利用率,降低网络成本,频谱利用率是GSM的4倍以上;二是提升用户体验,VoLTE引入的高清语音和视频编码提高了通信质量,而且VoLTE的呼叫持续时长大幅缩短;三是VoLTE与融合通信套件(Rich Communication Suite,简称RCS)的无线集成可以带来更加丰富的业务。
增强型语音服务(Enhanced Voice Service,简称EVS)是专为分组交换网络而设计的第三代合作伙伴项目(the 3rd Generation Partnership Project,简称3GPP)实时通信语音编解码器。与传统的语音编解码器相比,EVS可实现全高清语音通话质量,不仅可以进行自然的语音通信,而完整音频频谱还能够再现音乐环境氛围。EVS的语音编码参数包括语音编码速率、采样率、编码工作模式、带宽模式和实时传输协议(Real Time Protocol,简称RTP)负载模式等,每一种编码参数都可以在提供的选项范围内进行调整,以便在语音质量和系统容量之间取得平衡,为网络运营商提供灵活的部署选项,例如,语音编码速率支持13种语音编码速率,其速率范围为从5.9~128k变化,语音编码速率可以在该范围内连续调整,因此当系统容量增加的时候,语音质量不会突然变差。
现有EVS方案中,对EVS的语音编码参数采用静态配置方式,即预先为系统设置一种编码模式,在这种编码模式下,语音编码参数都是固定的,因此系统容量也是固定的。编码模式一经确定,在对系统设置进行修改之前,系统中的所有呼叫都使用这种编码模式。但是,在实际应用中,不同应用场景,不同时段,对系统容量或语音质量的要求是不一致的。例如当网络处于高负荷状态时,往往会采用较低的编码速率,以牺牲语音质量来提升系统容量。如果使用静态配置的方法,很难预先设置出一种适用于所有场景的编码模式,并且在设置之后,也无法根据负荷或信道质量的变化,对编码模式进行动态调整。

EVS可实现全高清语音通话质量,不仅可以进行自然的语音通信,而完整音频频谱还能够再现音乐环境氛围,而被广泛应用在VoLTE中。本发明实施例提供了一种语音自适应参数的调整方法,能够动态调整EVS编码参数,以及在利用EVS编码时的语音组包参数。
请参阅图1a和图1b,其中,图1a为本发明一些实施例提供的应用场景示意图。在图1a中,终端(User Equipment,简称UE)中的UE1和UE2工作在同一个eNB的覆盖范围内,UE1和UE2在通信连接建立时,通过会话描述协议(Session Description Protocol,简称SDP)协商编码类型,在本发明实施例中UE1和UE2选择的编码类型为EVS。
在通信过程中,UE1可以向eNB发起参数调整请求或者由eNB决定进行参数调整,然后将UE1和/或UE2的语音自适应参数发送给eNB,eNB在接收到UE1和/或UE2的媒体自适应参数,由于eNB具备直接感知无线空口质量的能力,eNB根据通信信道情况来确认UE1和/或UE2的语音自适应参数是否需要调整。并在确定后发送调整命令,以便UE1和/或UE2进行语音自适应参数调整。同样,UE2可以向eNB发起参数调整请求或者由eNB决定进行参数调整,然后将UE1和/或UE2的语音自适应参数发送给eNB,eNB根据通信信道情况来确认UE1和/或UE2的语音自适应参数是否需要调整。并在确定后发送调整命令,以便UE1和/或UE2进行语音自适应参数调整。当然,还可以由核心网设备向eNB发送UE1和/或UE2的语音自适应参数,并且eNB将参数调整命令发送给核心网设备,由核心网设备进行UE1和/或UE2的语音自适应参数调整。
请参阅图1b中,图1b为本发明另一些实施例提供的应用场景示意图,在图1b中,UE1工作在eNB1的覆盖范围内,UE2工作在eNB2的覆盖范围内,UE1和UE2在通信连接建立时,通过SDP协商编码类型,在本发明实施例中UE1和UE2选择的编码类型为EVS。
在通信过程中,UE1可以向eNB1发起参数调整请求或者由eNB1决定进
行参数调整,然后将UE1和/或UE2的语音自适应参数发送给eNB1,eNB1在接收到UE1和/或UE2的媒体自适应参数,由于eNB1具备直接感知无线空口质量的能力,eNB1根据通信信道情况来确认UE1和/或UE2的语音自适应参数是否需要调整。并在确定后发送调整命令,以便UE1和/或UE2进行语音自适应参数调整。同样,UE2可以向eNB2发起参数调整请求或者由eNB2决定进行参数调整,然后将UE1和/或UE2的语音自适应参数发送给eNB2,eNB2根据通信信道情况来确认UE1和/或UE2的语音自适应参数是否需要调整。并在确定后发送调整命令,以便UE1和/或UE2进行语音自适应参数调整。当然,还可以由核心网设备向eNB1或eNB2发送UE1和/或UE2的语音自适应参数,并且eNB1或eNB2将参数调整命令发送给核心网设备,由核心网设备进行UE1和/或UE2的语音自适应参数调整。
当然,在上述图1a和图1b所示的应用场景中,eNB可以根据信道情况确定出UE1或UE2可以调整媒体自适应参数以获得更好的通信质量,以提高用户体验感,但是可以理解,eNB给到的调整命令仅是一个调整指示,UE1和UE2可以自行决定接受调整或者是放弃调整。
当然,上述图1a和图1b仅是给出本发明的2个应用场景示意图,在上述图1a和图1b的基础上经过变形或者改变其它应用场景能够适用本发明方案的,也属于本发明的保护范围,在此不再一一举例。
请参阅图2,图2为本发明一些实施例提供的语音自适应参数的调整方法的流程示意图;如图2所示,一种语音自适应参数的调整方法可包括:
201、获取通信设备的语音自适应参数,所述语音自适应参数包括增强型语音服务EVS编码参数和/或语音组包参数;
可以理解,上述通信设备可以包括第一通信和/或第二通信设备,例如图1a和图1b所示的UE1和/或UE2。通信设备还可以是其他具有信源编解码能力的服务器或媒体网关等设备。这里仅以UE设备为例。
在本发明一些实施例中,步骤201中具体包括:获取第一通信设备的语音自适应参数,和/或获取第二通信设备的语音自适应参数,第一通信设备的语音自适应参数包括EVS编码参数和/或语音组包参数,第二通信设备的语音自适应参数包括EVS编码参数和/或语音组包参数。
其中,所述EVS编码参数包括编码模式、EVS工作模式、EVS带宽模式编码速率、采样率和EVS信道感知模式的编码冗余中的至少一种,所述语音组包参数包括RTP负载格式和语音通道数中的至少一种。
EVS编码有两种工作模式:EVS主操作模式(EVS Primary Perational Mode(EVS Primary mode))、EVS AMR-WB交互操作模式的AMR-WB内部可操作(AMR-WB Inter-Operable(EVS AMR-WB IO mode))。其中EVS主操作模式包括11种可以工作在固定速率或可变速率模式的速率,1个平均比特率和一个SID的比例率。AMR-WB内部可操作包括9种编码模式和SID,并且与AMR-WB编码兼容,即EVS编码器产生的语音帧能够被AMR-WB的译码器正确译码出语音信息,反之亦然。
EVS主操作模式对应13.2 kbps速率的模式下有8中冗余模式,对应不同的冗余模式,可以用3个比特进行指示。
EVS的RTP负载格式有两种格式:紧凑格式(Compact Format)和头完整格式(Header-Full Format)。两种格式的选择根据所需要的功能以及是否是单语音帧发送来决定。在一次会话中可以在两种格式中切换,也可以限制在头完整格式一种格式上。紧凑格式只用于在一个RTP包中发送一个语音帧的情况,发送效率较高。在EVS主操作模式下只含一个语音帧,无额外的RTP负
载头信息;在EVS AMR-WB交互操作模式的AMR-WB内部可操作下,含一个语音帧和3比特共态抑制比(Common Mode Rejection,简称CMR)域。头完整格式可以包含一个或多个语音帧,含有RTP的头信息域,可以用来传输完整的信息。无线接入网设备可以根据需要传递的信息和传输效率考虑改变EVS的RTP负载格式。
无线接入网设备根据信道质量还可以选择调整一个语音包中可以包含的语音通道数。信道质量好时,可以将双声道或更多声道的语音数据打包到一个语音包中进行传输,提高语音的业务感受。
可以理解,在本发明实施例中,可以是无线接入网设备自行去确认是否要调整第一通信设备或者第二通信设备的语音自适应参数,还可以是由第一通信设备请求无线接入网设备确认,因此,在本发明一些实施例中,在步骤201之前还包括:接收所述第一通信设备发送的参数调整请求,所述参数调整请求用于请求确认是否需要调整所述第一通信设备的语音自适应参数和/或所述第二通信设备的语音自适应参数。
其中,无线接入网设备可以从通信设备中获取第一通信设备或者第二通信设备的语音自适应参数,也可以从核心网设备获取第一通信设备或者第二通信设备的语音自适应参数。
具体地,在本发明一些可实施的方式中,步骤201包括:接收所述第一通信设备发送的无线资源控制RRC消息,所述RRC消息携带有所述第一通信设备的语音自适应参数和/或第二通信设备的语音自适应参数。
如图1a和图1b所示,第一通信设备可以是UE1或UE2,在图1a中,eNB接收UE1或UE2发送的RRC消息,RRC消息包括UE1和/或UE2的语音自适应参数。但在图1b中,UE1作为第一通信设备时,UE2作为第二通信设备,eNB1接收UE1发送的RRC消息,RRC消息包括UE1和/或UE2的语音自适应参数。UE2作为第一通信设备时,UE2作为第一通信设备,eNB2接收UE2发送的RRC消息,RRC消息包括UE1和/或UE2的语音自适应参数。
在本发明另一些可实施的方式中,步骤201还可以包括:接收所述第一通信设备发送的媒体访问控制MAC消息,所述MAC消息携带有所述第一通信设备的语音自适应参数和/或第二通信设备的语音自适应参数。
如图1a和图1b所示,第一通信设备可以是UE1或UE2,在图1a中,eNB接收UE1或UE2发送的MAC消息,MAC消息包括UE1和/或UE2的语音自适应参数。但在图1b中,UE1作为第一通信设备时,UE2作为第二通信设备,eNB1接收UE1发送的MAC消息,MAC消息包括UE1和/或UE2的语音自适应参数。UE2作为第一通信设备时,UE2作为第一通信设备,eNB2接收UE2发送的MAC消息,MAC消息包括UE1和/或UE2的语音自适应参数。
在本发明另一些可实施的方式中,步骤201还可以包括:接收核心网设备发送的所述第一通信设备的语音自适应参数和/或所述第二通信设备的语音自适应参数。
其中,核心网可以是移动性管理实体(Mobility Management Entity,简称MME)等,其中,如图1a和图1b所示,MME可以获取到UE1或UE2的语音自适应参数,然后发送给eNB。在图1a中,MME获取到UE1和/或UE2的语音自适应参数发送给eNB。在图1b中,MME获取到UE1和/或UE2的语音自适应参数发送给eNB1或eNB2,在发送给eNB1时,UE1为第一通信设备,UE2为第二通信设备,反之,当发送给eNB2时,UE1为第二通信设备,UE2为第一通信设备。
202、在确定需要调整所述语音自适应参数时,发送参数调整命令,所述参数调整命令包括所述通信设备的目标语音自适应参数,所述参数调整命令用于指示将所述通信设备的所述语音自适应参数调整成所述目标语音自适应参数。
可以理解,无线接入网设备如eNB能够直接感知到整个无线空口信道质量,然后根据其感知到的信道质量来确认是否需要进行通信设备的语音自适应参数的调整。因此,在本发明一些实施例中,步骤202具体包括:根据通信信道信息,判断是否需要调整所述通信设备的所述语音自适应参数,在确定需要调整所述通信设备的所述语音自适应参数时,发送所述参数调整命令,其中,所述通信信道信息包括丢包率、包时延、包时延抖动频率、信号干扰噪声比SINR、信道质量指示和信道负载中的至少一种。
例如在丢包率、信道负载大于一定门限时,调整语音编码速率到低一级的编码速率上;当语音质量低于一定门限时,采用冗余的发送方式进行语音帧的
多次发送;考虑到小数据的语音帧数据传输的效率,还可以调整语音包的帧聚合度,将多个语音帧数据聚合到一个语音包中传送。反之,可以提高语音速率,减少冗余发送和语音包聚合度。需要注意的是,这多种自适应参数的调整可以单个参数的调整,也可以是多个参数的联合调整。本发明不做具体限定。
在本发明一些实施例中,上述根据通信信道信息,判断是否需要调整所述通信设备的所述语音自适应参数包括:根据上行通信信道信息,判断是否需要调整所述第一通信设备的语音自适应参数;和/或根据下行通信信道信息,判断是否需要调整所述第二通信设备的语音自适应参数;并在确定需要调整所述第一通信设备的语音自适应参数和/或在确定调整所述第二通信设备的语音自适应参数时,发送所述参数调整命令。
例如,在图1a中,UE1为第一通信设备,发送上行数据,在eNB中根据上行通信信道,去判断UE1的语音自适应参数是否需要调整,eNB根据下行通信信道,去判断UE2的语音自适应参数是否需要调整。下行信道的质量可以根据UE上报的测量报告值,如信道质量指示(Channel Quality Indicaton,简称CQI)、功率余量(Power Headroom Report,简称PHR)等来进行判断。
可以看出,在本发明实施例中,由无线接入网设备参与通信设备的语音自适应参数的调整,由于无线接入网设备能够直接感知无线空口质量,调整及时,提高用户体验感,而且能够充分利用资源。

可以理解,参数调整命令还可以包括第二通信设备的目标语音自适应参数,第一通信设备在接收到所述参数调整命令之后,向所述第二通信设备发送所述第二通信设备的目标语音自适应参数。
其中,第一通信设备可以采用RTCP扩展命令RTCP_APP的方式或SDP
协议的会话发起协议(Session Initiation Protocol,简称SIP)消息形式将目标媒体自适应参数发送给第二通信设备。
第一通信设备可以是图1a和图1b中的UE1或UE2,在图1a中,第一通信设备是UE1时,第二通信设备是UE2,第一通信设备接收eNB发送的参数调整命令;反之,第一通信设备是UE2时,第二通信设备是UE1,第一通信设备同时从eNB中接收到参数调整命令。在图1b中,第一通信设备是UE1时,第二通信设备是UE2,第一通信设备从eNB1中接收到参数调整命令;反之,第一通信设备是UE2时,第二通信设备是UE1,第一通信设备从eNB2中接收到参数调整命令。
其中,所述第一通信设备的语音自适应参数和第二通信设备的语音自适应参数,分别包括EVS编码参数和/或语音组包参数,具体可以参阅图2实施例中对EVS编码参数和语音组包参数的介绍。
在本发明一些实施例中,可以由第一通信设备请求无线接入网设备来判断是否调整语音自适应参数,当然,还可以由无线接入网设备根据无线通信信道质量来进行确定。因此,在步骤301之前还包括:所述第一通信设备向所述无线接入网设备发送参数调整请求,所述参数调整请求用于请求所述无线接入网设备确认是否需要调整所述第一通信设备的语音自适应参数。
当然,参数调整请求中还可以包括第二通信设备的语音自适应参数。
