当前技术中,当采用EVS编码时,与传统的AMR编码相比,在达到相同语音质量的前提下,EVS编码需要的编码速率会更低。然而,采用EVS编码时的资源利用率会较低,因此,如何提高EVS编码时的资源利用率,是一个亟需解决的问题。

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,所描述的实施例仅仅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。
图1所示为本申请实施例提供的一种语音传输数据方法的实施环境图。如图所示,所述语音传输数据方法应用于LTE通信系统,在LTE通信系统中,各个基站(Evolved Node B,eNB)之间通信连接,并接入服务网关(Serving Gateway,S-GW),终端(user equipment,UE)通过接入基站,实现通信。在本实施方式中,当需要采用语音通信即VoIP时,终端和基站都会先采用语音压缩算法对语音数据进行压缩处理,然后把语音数据按照TCP/IP(Transmission Control Protocol/Internet Protocol,网络通讯协议)标准进行打包,经过IP网络和空口传输将数据包发送至接收方,再由接收方对数据进行解压和还原。图2所示为语音业务数据传输中包头信息示意图。如图所示,语音数据包依次经过了PDCP(Packet Data Convergence Protocol,分组数据汇聚层协议)层、RLC(Radio Link Control,无线链路控制)层以及MAC(Media Access Control,媒体接入控制)层,在每一层会添加对应的数据包头部。所述语音数据可能包括RTP(Real-time Transport Protocol,实时传输协议)包头、UDP(User Datagram Protocol,用户数据包协议)包头、IP(Internet Protocol,互联网协议)包头、PDCP包头、RLC包头以及MAC包头。其中,RTP包头、UDP包头以及IP包头经过压缩可生成RoHC(Robust header compression,鲁棒性头压缩)包头。
图3为本申请实施例提供的一种语音数据传输方法第一实施例的流程图。在本实施方式中,该语音数据传输方法可应用于终端上,也可以应用于基站上,即可以是在上行业务中,终端采用该语音数据传输方法将语音数据传输给基站;也可以是在下行业务中,基站采用该语音数据传输方法将语音数据传输给终端。该语音数据传输方法包括以下步骤S301-S303。为了方便描述,下面采用上行业务举例来进行说明,即由终端来执行该语音数据传输方法。本领域技术人员可以理解的是,当在下行业务中时,由基站执行该语音数据传输方法的步骤与之类似,在此不赘述。
在步骤S301中,在执行语音业务时,发送包括完整包头信息的语音数据包。
本步骤中,当终端在执行语音时,首先发送包括完整包头信息的语音数据包到基站。本实施方式中,完整包头信息是指该语音数据包未经过压缩,该语音数据包完整的包括了RTP包头、UDP包头以及IP包头。可选地,所述语音数据包还可进一步包括PDCP包头、RLC包头以及MAC包头。
在步骤S302中,若接收到用于指示所述语音数据包接收成功的反馈消息,则对待传输语音数据包的包头信息中的一个或者多个包头参数进行调整,生成目标语音数据包,其中所述目标语音数据包的尺寸满足传输块大小适配条件。
本步骤中,基站在接收到所述包括完整包头信息的语音数据包了之后,会判断自身是否具备头压缩条件,若具备,则基站根据该语音数据包向终端返回反馈消息,所述反馈信息用于指示所述语音数据包接收成功。可选地,该反馈信息可以用于指示支持语音数据包的头压缩。可选地,该反馈消息为RRC(Radio Resource Control,无线资源控制)信令。其中,基站判断是否具备头压缩条件可以通过判断是否具备对应压缩方式的文件(Profile)来确定。其中,压缩方式的文件根据具体压缩方式的不同而有所不同。当终端接收到基站根据所述语音数据包返回的反馈消息时,则触发对应的头压缩方案,对待传输语音数据包的包头信息中的一个或者多个包头参数进行调整,生成目标语音数据包。
其中,调整后得到的包头信息的尺寸满足传输块大小适配条件。当前技术中,为了尽可能的提升LTE系统中的语音性能,在LTE标准中设计TBS(Transport Block Size,传输块大小)时,对于VoIP业务有特殊考虑,TBS 会尽可能的适配语音包的大小,现有的TBS表格正是基于AMR编码设计。由于在采用EVS编码时,速率接近时的EVS语音包会比采用AMR编码的AMR语音包大,导致现有的EVS编码无法适配TBS,资源利用率较低。因此需要对EVS语音包进行相应的压缩,以适配现有的TBS。在本实施方式中,若当前采用的语音编码方式为EVS编码,由于EVS编码下,同速率的EVS语音数据包比AMR语音数据包大2个字节,因此,当采用EVS编码时,需要将包头信息压缩2个字节,以满足现有的TBS适配条件。参照图2所示,在现有的语音数据包中,头开销总和为8个字节,其中包括了RoHC包头占用3个字节,PDCP包头占用1个字节,RLC包头占用1个字节,MAC包头占用1个字节,另外还包括2个额外字节,所述额外字节可用于RoHC包头的填充,还可用于BSR(Buffer Status Report,缓存状态上报)以及PHR(Power headroom Report)等控制元素传输。在本实施方式中,可以通过调整RoHC包头、RLC包头以及额外字节来实现对TBS的适配,即通过调整RoHC包头、RLC包头、额外字节这一个或者三个参数使得头开销降低为6个字节。可以理解的是,具体如何调整包头参数可以保存为对应压缩方式的文件中。
下面举例说明如何对待传输语音数据包的包头信息中的一个或者多个包头参数进行调整。
在一种实施方式中,所述对待传输语音数据包的包头信息中的一个或者多个包头参数进行调整,包括:删除所述包头信息中的实时传输协议包头、用户数据包协议包头以及互联网协议包头;添加所述实时传输协议包头的序列号信息中的低8位信息。
具体的,在本实施方式中,由于RoHC包头是由RTP包头、UDP包头以及IP包头压缩得到的,由于在步骤S301中已经传输了完整的数据包,因此后续可以根据该完整的数据包还原出后续数据包的UDP包头以及IP包头,而RTP包头则只需要获取RTP包头的序列号部分即可。因此,在本实施方式中,不进行RoHC的压缩,而是直接删除包头信息中的RTP包头、UDP包头以及IP包头。为了后续的还原,还需要添加RTP包头的序列号信息(SN)中的低8位信息。可选的,还需要添加一定数量的额外字节。在本实施方式中,此时的头开销总和为6个字节,其中,RTP包头序列号低8位信息占用1个字节,PDCP包头占用1个字节,RLC包头占用1个字节,MAC包头占用1个字节, 额外字节占用2个字节。本实施方式中,通过传输RTP包头中序列号的低8位信息,减少了头开销,实现对现有TBS的适配,从而减少了不必要的填充,提高了数据解调的性能。
在另一种实施方式中,所述对待传输语音数据包的包头信息中的一个或者多个包头参数进行调整,包括:删除所述包头信息中的实时传输协议包头、用户数据包协议包头以及互联网协议包头;添加所述实时传输协议包头的序列号信息;将无线链路控制层的传输模式配置为透明模式。
具体的,在本实施方式中,同样删除了RTP包头、UDP包头以及IP包头,添加了RTP包头的序列号信息,与上一实施例不同之处在于,本实施例中,添加的RTP包头的序列号信息为完整的,占用2个字节。此外,在本实施方式中,还需要将RLC层的传输模式配置为透明模式(Transparent Mode,TM)。其中,RLC层的传输模式包括透明模式、非确认模式(Unacknowledged Mode,UM)以及确认模式(Acknowledged Mode,AM),当传输模式为透明模式时,RLC层直接根据报文类型执行转发操作,因此此时无需添加RLC头,不需要传输RLC包头,从而可以节省1个字节。可选的,还需要添加一定数量的额外字节。此时的头开销总和为6个字节,其中,RTP包头序列号信息占用2个字节,PDCP包头占用1个字节,MAC包头占用1个字节,额外字节占用2个字节。本实施方式中,通过配置RLC层的传输模式以及传输RTP包头的序列号信息,能够减少头开销,适配现有的TBS。
在又一种实施方式中,所述对待传输语音数据包的包头信息中的一个或者多个包头参数进行调整,包括:删除所述包头信息中的实时传输协议包头、用户数据包协议包头以及互联网协议包头;添加鲁棒性头压缩包头,所述鲁棒性头压缩包头是根据实时传输协议包头、用户数据包协议包头以及互联网协议包头压缩得到;将无线链路控制层的传输模式配置为透明模式。
具体的,在本实施方式中,对RoHC包头不做调整,即还是删除RTP包头、UDP包头以及IP包头,根据RTP包头、UDP包头以及IP包头压缩得到RoHC头。和上一实施方式相同,本实施方式中,同样将无线链路控制层的传输模式配置为透明模式。此外,为了达到将头开销减小到6个字节的目的,还需要进一步的将额外字节调整为1字节。此时的头开销为6个字节,其中,RoHC包头占用3个字节,PDCP包头占用1个字节,MAC包头占用1个字节, 额外字节占用1个字节。需要说明的是,由于额外字节用于RoHC包头的填充,还可用于BSR以及PHR等控制元素。在将额外字节调整为1个字节了之后,所述额外字节将只能支持RoHC1个字节的变化,而且也无法支持与MAC CE(Control Element,控制元素)的复用。本实施方式中,通过配置RLC层的传输模式以及减少额外字节的大小,能够减少头开销,适配现有的TBS。
需要说明的是,为了适配现有的TBS,需要将EVS编码的语音数据包减少2个字节,本申请实施例中通过调整RoHC包头、RLC包头的大小来实现,上述三种实施方式只是列举了其中的部分实施方式。本领域技术人员可以理解的是,还可以通过其他方式调整包头参数来实现对TBS的适配,在此不赘述。
在步骤S303中,发送所述目标语音数据包。
本步骤中,终端将压缩后得到的目标语音数据包发送至基站,基站根据该目标语音数据包执行对应的解压缩和还原操作,以得到传输的语音数据,实现通信。
本申请实施例中的语音数据传输方法,在进行语音数据传输时,首先传输完整的数据包,再对后续待传输的数据包采用预置的包头压缩策略进行压缩,从而使得数据包适配现有的传输块大小,减少了不必要的填充,提高了资源利用率。
图4为本申请实施例提供的一种语音数据传输方法第二实施例的流程图。在本实施方式中,该语音数据传输方法可应用于终端上,也可以应用于基站上,即可以是在上行业务中,终端采用该语音数据传输方法将语音数据传输给基站;也可以是在下行业务中,基站采用该语音数据传输方法将语音数据传输给终端。该语音数据传输方法包括步骤S401-S403。为了方便描述,下面采用上行业务举例来进行说明,即由终端来执行该语音数据传输方法。本领域技术人员可以理解的是,当在下行业务中时,由基站执行该语音数据传输方法的步骤与之类似,在此不赘述。
在步骤S401中,在执行语音业务时,发送包括完整包头信息的语音数据包。
本步骤中,当终端在执行语音时,首先发送包括完整包头信息的语音数据包到基站。本实施方式中,完整包头信息是指该语音数据包未经过压缩,该语音数据包完整的包括了RTP包头、UDP包头以及IP包头。可选地,所述语音 数据包还可进一步包括PDCP包头、RLC包头以及MAC包头。
在步骤S402中,若接收到根据所述语音数据包返回的回复消息,则对待传输语音数据包的包头信息中的一个或者多个包头参数进行调整,生成目标语音数据包。
本步骤中,基站在接收到所述包括完整包头信息的语音数据包了之后,会判断自身是否具备头压缩条件,若具备,则基站根据该语音数据包向终端返回反馈消息,所述反馈信息用于指示所述语音数据包接收成功。可选地,该回复消息为RRC(Radio Resource Control,无线资源控制)信令。其中,基站判断是否具备头压缩条件可以通过判断是否具备对应压缩方式的文件(Profile)来确定。当终端接收到基站根据所述语音数据包返回的反馈消息时,则对待传输语音数据包的包头信息中的一个或者多个包头参数进行调整,生成目标语音数据包。
其中,所述对待传输语音数据包的包头信息中的一个或者多个包头参数进行调整包括:
删除所述包头信息中的实时传输协议包头、用户数据包协议包头以及互联网协议包头;添加所述实时传输协议包头的序列号信息中的低8位信息;将无线链路控制层的传输模式配置为透明模式。
具体的,在本实施方式中,首先删除RTP包头、UDP包头以及IP包头,添加对应的RTP包头的序列号的低8位信息。另外,还需要将RLC层的传输模式配置为透明模式。此外,也不对包头信息添加额外信息。此时的头开销为最大化去除冗余之后的大小,头开销总和为3个字节,其中,RTP包头序列号低8位信息占用1个字节,PDCP包头占用1个字节,MAC包头占用1个字节。本实施方式中,通过传输RTP头中序列号的低8位信息,配置RLC层的传输模式,不添加额外字节,最大化的减少了头开销,从而减少了在空口传输语音包的传输块大小,从而可以使用更低阶的调制编码方案,增强了VoIP业务的上行覆盖。
在步骤S403中,发送所述目标语音数据包。
本步骤中,终端将压缩后得到的目标语音数据包发送至基站,基站根据该目标语音数据包执行对应的解压缩和还原操作,以得到传输的语音数据,实现通信。
本申请实施例中的语音数据传输方法,在进行语音数据传输时,首先传输完整的数据包,再对后续的数据包进行压缩,通过删除所述包头信息中的实时传输协议包头、用户数据包协议包头以及互联网协议包头,添加所述实时传输协议包头的序列号信息中的低8位信息,同时配置RLC层的传输模式为透明模式,能够最大化的减少头开销,减少在空口传输语音包的传输块大小,从而可以使用更低阶的调制编码方案,增强了VoIP业务的上行覆盖。
图5为本申请实施例提供的一种语音数据传输方法第三实施例的流程图。在本实施方式中,该语音数据传输方法可应用于终端上,也可以应用于基站上,当终端或者基站接收到语音数据之后,需要对语音数据进行解压缩以还原得到其中的数据信息。该语音数据传输方法包括步骤S501-S502。为了方便描述,下面采用上行业务举例来进行说明,即由基站来执行该语音数据传输方法。本领域技术人员可以理解的是,当在下行业务中时,由终端执行该语音数据传输方法的步骤与之类似,在此不赘述。
在步骤S501中,在执行语音业务时,若接收到包括完整包头信息的语音数据包,则发送用于指示所述语音数据包接收成功的反馈消息。
本步骤中,当基站接收到终端发送的包括了完整包头信息的语音数据包时,基站判断自身是否具备头压缩条件,如具备,则基站发送用于指示所述语音数据包接收成功的反馈消息。可选地,所述反馈消息为RRC信令。其中,基站判断是否具备头压缩条件可以通过判断是否具备对应压缩方式的文件来确定。
在步骤S502中,接收目标语音数据包,根据所述完整的数据包对所述目标语音数据包进行还原处理,其中,所述目标语音数据包中包含实时传输协议包头的序列号信息。
本步骤中,当基站接收到终端经过压缩了之后发送的目标传输数据了之后,根据步骤S501中接收到的完整的数据包对所述目标传输数据进行还原处理。所述还原处理包括解压缩以及推测得到相应的数据信息。
由于终端压缩数据包的方式不同,还原数据包的方式也会相应的不同,下面进行详细的说明。
在一种实施方式中,根据所述完整的数据包对所述目标传输数据进行还原处理,包括:解析所述目标语音数据包,获取所述目标语音数据包中包含的实 时传输协议包头的序列号信息;根据所述完整的数据包还原所述目标语音数据包的实时传输协议包头、用户数据包协议包头以及互联网协议包头,其中,所述实时传输协议包头的时间戳信息为根据所述完整的数据包以及所述实时传输协议包头的序列号信息计算得到。
具体的,在本实施方式中,终端发送的目标传输数据只包含了RTP包头的序列号信息,其中所述序列号信息可以是完整的序列号信息,还可以是只包括序列号的低8位信息。根据所述RTP包头的序列号信息可以计算出所述RTP包头的时间戳信息。进一步的,根据得到的RTP包头的时间戳信息以及接收到的完整的数据包中包含的完整的RTP包头、UDP包头以及IP包头,可以对目标传输数据中的RTP包头、UDP包头以及IP包头进行还原。下面详细介绍如何进行还原操作。
当数据包头为RTP包头时,RTP包头中的字段可以分为不变的字段以及变化的字段两类,其中,不变的字段包括:V(版本)、P(填充)、X(扩展)、CC(提供源计数)、M(标记)、PT(载荷类别)、SSRC identifier(同步源标识符)和CSRC identifier(提供源标识符),变化的字段包括:SN(序列号信息)和Timestamp(时间戳信息)。在本实施方式中,目标传输数据中包含了序列号信息,根据序列号信息可以计算得到时间戳信息,而不变的字段可以采用与最先接收到的完整的数据包中的对应字段相同的值,以此实现对后续数据包头中的RTP包头的还原。
当数据包头为UDP包头时,UDP包头包括:Source Port(源端进程使用端口)、Destination Port(目的端进程使用端口)、Length(数据包长度)以及CheckSum(数据报校验和)。其中,Source Port以及Destination Port可以根据最先接收到的完整的数据包中的对应字段相同的值,Length可以根据数据包的长度计算得到,CheckSum可以用0填充,以此实现对后续数据包头中的UDP包头的还原。
当数据包头为IP包头时,IP包头中的字段可以分为变化字段、可推算字段以及不变字段三类。其中,变化字段包括:Type of service(服务类型)、Identification(标识)和Time to live(生存时间);可推算字段包括:Total Length(总长度)、Header Checksum(包头校验位);不变字段包括:Version(版本)、IHL(IP Header Length,首部长度)、Flags(标示)、Fragment Offset(片段偏 移)、Protocol(协议)、Source Address(源地址)、Destination Address(目的地址)。在本实施方式中,在进行还原操作时,不变字段可以采用与最先接收到的完整的数据包中的对应字段相同的值;变化字段中的Type of service以及Time to live也可以采用与最先接收到的完整的数据包中的对应字段相同的值,变化字段中的Identification可根据最先接收到的完整的数据包中的对应字段的值按照一定规则进行添加,比如可以在前一包的数值上加1;可推算字段中的Total Length可以根据数据包的长度计算得到,Header Checksum则可根据包头中的其余值计算得到,以此实现对后续数据包头中的IP包头的还原。
在另一种实施方式中,根据所述完整的数据包对所述目标传输数据进行还原处理,包括根据所述目标传输数据的鲁棒性头压缩包头还原所述目标传输数据的实时传输协议包头、用户数据包协议包头以及互联网协议包头。
具体的,在本实施方式中,对RTP包头、UDP包头以及IP包头采取了鲁棒性头压缩,生成了RoHC包头。在进行还原时,只需要根据RoHC包头进行对应的还原即可得到相应的目标传输数据的RTP包头、UDP包头以及IP包头。
本申请实施例中的语音数据传输方法,在进行语音数据传输时,若接收到包括完整包头信息的语音数据包,则通过回复信息告知发送方可以进行数据压缩,在接收到压缩后的目标数据之后,对目标数据进行还原,得到相应的数据信息,从而使得传输过程中能够减少了不必要的填充,提高了资源利用率。
