具体实施方式
下面将结合附图对本申请实施例作进一步地详细描述。
图1示例性示出了本申请实施例适用的一种系统架构示意图，如图1所示，本申请实施例适用的系统架构至少包括具有通信功能的终端设备101。终端设备101接入基站102中。可选地，终端设备101和对端的终端设备可接入同一个基站，也可接入不同的基站中，本申请实施例中图1仅仅为示例性内容，并不对本申请应用场景进行限定。
以下，对本申请中的部分用语进行解释说明，以便与本领域技术人员理解。
本申请实施例中的基站可以是用于与终端设备进行通信的设备，例如，可以是GSM系统或CDMA中的基站(Base Transceiver Station，简称BTS)，也可以是WCDMA系统中的基站(NodeB，简称NB)，还可以是LTE系统中的演进型基站(Evolutional Node B，简称eNB或eNodeB)，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络侧设备或未来演进的PLMN网络中的网络设备等。
本申请实施例中的终端设备可以包括具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile station,MS)，终端(terminal)，终端设备(Terminal Equipment)等等。为方便描述，本申请中，简称为用户设备或UE。
图2示例性示出了本申请实施例提供的一种编码速率的调整方法，如图2所示，该方法包括：
步骤201，终端设备向基站上报编码速率调整能力指示信息，其中，编码速率调整能力指示信息用于指示终端设备是否支持跨级速率调整；基站接收终端设备的编码速率调整能力指示信息；
步骤202，若终端设备支持跨级速率调整，则基站确定终端设备的跨级目标编码速率，跨级目标编码速率与终端设备的当前编码速率不相邻或相邻；其中，跨级目标编码速率与终端设备的当前编码速率都是两个通信的终端设备之间协商的编码速率集中的编码速率；编码速率集中包括多个编码速率；跨级目标编码速率与终端设备的当前编码速率相邻具体是指：在两个通信的终端设备之间协商的编码速率集中：跨级目标编码速率与当前编码速率为相邻的两个编码速率；
步骤203，基站向终端设备发送跨级目标编码速率；终端设备接收基站发送的跨级目标编码速率；
步骤204，若终端设备支持跨级速率调整，终端设备将当前编码速率调整为跨级目标编码速率。
本申请实施例提供的编码速率的调整方法可适用于语音类的编码速率的调整，也可应用于视频类的编码速率的调整，比如视频电话等等。
本申请实施例中由于基站获取终端设备的编码速率调整能力，因此若终端设备支持跨级速率调整，则在基站确定并下发终端设备的跨级目标编码速率后，该终端设备可以将当前编码速率调整为跨级目标编码速率，从而提高了终端设备调整编码速率的灵活性，进而提升了系统性能，提升了用户体验。
可以理解，上述实施例提供的编码速率的调整方法也适用于非跨级速率调整。
可选地，上述步骤201之前，进行通信的两个终端设备之间协商两个终端设备的编码速率调整能力，编码速率调整能力具体可为终端设备是否支持跨级速率调整，比如可通过 会话描述协议(session description protocal，SDP)协商两个终端设备的编码速率调整能力。可选地，上述步骤201之前，基站可向终端设备发送能力查询请求，能力查询请求用于查询终端设备的编码速率调整能力，终端设备接收到该能力查询请求之后，可向基站上报编码速率调整能力指示信息。另一种可选地实施方案中，终端设备在与对端的终端设备协商了终端设备的编码速率调整能力之后，终端设备主动向基站上报编码速率调整能力指示信息。
本申请中一种可选地实施例中，是否支持跨级速率调整的能力可通过mode-change-neighbor参数来体现，也就是说，编码速率调整能力指示信息具体可为mode-change-neighbor参数的值，比如mode-change-neighbor＝1，则表示终端设备不支持跨级速率调整，若mode-change-neighbor＝0，则表示终端设备支持跨级速率调整。
进行通信的两个终端设备之间经过协商，两个通信的终端设备之间也可协商两个终端设备所支持的速率类型，还可确定出两个终端设备适用的编码速率集，该编码速率集中包括的任一个编码速率，两个终端设备均能支持。终端设备支持的编码速率集中包括多个编码速率，跨级目标编码速率和非跨级编码速率均为多个编码速率中的一个。本申请实施例中，编码速率集中包括的多个编码速率按大小排序。若终端设备不支持跨级速率调整，则终端设备仅能在相邻的两个编码速率之间进行速率调整，若终端设备支持跨级速率调整，则终端设备可以调整至编码速率集中包括的任一个编码速率。
上述步骤203中，举个例子，比如编码速率集中支持5个编码速率，按大小排序依次为编码速率1、编码速率2、编码速率3、编码速率4和编码速率5。假设当前编码速率为编码速率3，则跨级目标编码速率可以为编码速率集中的任一个编码速率，比如为与编码速率3相邻的编码速率4，或者跨级目标编码速率为与编码速率3不相邻的编码速率1。步骤204中，若跨级目标编码速率为编码速率1，则跨级速率调整的终端设备可直接将编码速率从编码速率3调整至编码速率1。
本申请提供一种可选地实施方案，基站确定终端设备的跨级目标编码速率，包括：基站至少根据终端设备的当前编码速率和信道状况信息确定终端设备的跨级目标编码速率。可选地，终端设备可向基站上报终端设备的当前编码速率，基站也可通过检测等操作获取终端设备的当前编码速率。可选地，终端设备可向基站上报信道状况信息，基站也可通过检测等操作获取信道状况信息。信道状况信息可为能够反映信道质量的信息，比如网络负荷、网络质量等信息。具体来说，能反应网络质量的参数比如为：丢包率(packet loss rate)等；能反应网络负荷的参数比如为：物理资源块(physical resource block，PRB)利用率、控制信道元素(control channel element，CCE)利用率等。
可选地，基站可在网络质量较好的情况下，将终端设备的编码速率调高一些，从而获取金属氧化物半导体(metal-oxide-semiconductor，mos)增益，可在网络质量变差时，将终端设备的编码速率调低一些，获得丢包率增益和覆盖增益。再比如在网络负载重时，将终端设备的编码速率调低一些，从而缓解网络拥塞，再比如在网络负载轻时，将终端设备的编码速率调高一些，从而提高信令的通过率。再比如，基站可结合网络质量和网络负载两方面的因素，综合将终端设备的编码速率调整为一个较优的编码速率。
可选地，基站接收终端设备的编码速率调整能力指示信息，包括：基站通过媒体接入控制控制元素(Media Access Control Control Element，MAC CE)信令或者无线资源控制(Radio Resource Control，RRC)信令接收终端设备发送的编码速率调整能力指示信息。 相应地，可选地，终端设备向基站上报编码速率调整能力指示信息，包括：终端设备通过MAC CE信令或者RRC信令向基站上报编码速率调整能力指示信息。
本申请实施例中MAC CE是标准36.321中定义的MAC层的控制面消息。MAC CE信令可包括缓冲区状态报告(Buffer Status Report，BSR)，用于使终端设备上报上行数据量的信令；功率余量报告(Power Headroom Report，PHR)，用于使终端设备上报功率余量的信令等等，不同功能定义的MAC CE信令不同，所以本申请实施例中也可能是新定义一个MAC CE信令用于承载编码速率调整能力指示信息。
可选地，基站向终端设备发送跨级目标编码速率，包括：基站通过MAC CE信令或者RRC信令向终端设备发送跨级目标编码速率。相应地，可选地，终端设备接收基站发送的跨级目标编码速率，包括：终端设备通过MAC CE信令或者RRC信令接收基站发送的跨级目标编码速率。
本申请提供的另一个实施例中，编码速率调整方法还包括：若终端设备不支持跨级速率调整，基站确定终端设备的非跨级目标编码速率，非跨级目标编码速率与终端设备的当前编码速率相邻；基站向终端设备发送非跨级目标编码速率。
基于上述内容中所描述的两个终端设备协商后的编码速率集，举个例子，比如编码速率集中支持5个编码速率，按大小排序依次为编码速率1、编码速率2、编码速率3、编码速率4和编码速率5。假设当前编码速率为编码速率3，则非跨级目标编码速率仅仅可以为编码速率集中的编码速率4或编码速率2。也就是说，非跨级目标编码速率不可以与当前编码速率不相邻，如此，若终端设备不支持跨级速率调整也能够响应编码速率的调整的目的。
可选地，基站确定终端设备的非跨级目标编码速率，包括：基站至少根据终端设备的当前编码速率和信道状况信息确定终端设备的非跨级目标编码速率。可选地，终端设备可向基站上报终端设备的当前编码速率，基站也可通过检测等操作获取终端设备的当前编码速率。可选地，终端设备可向基站上报信道状况信息，基站也可通过检测等操作获取信道状况信息。信道状况信息可为能够反映终端设备的信道上的网络负荷、网络质量等信息。具体来说，能反应网络质量的参数比如为：丢包率(packet loss rate)等；能反应网络负荷的参数比如为：物理资源块(physical resource block，PRB)利用率、控制信道元素(control channel element，CCE)利用率等。
本申请还提供另一种实施例，若基站向终端设备发送跨级目标编码速率，而终端设备不支持跨级速率调整，此时终端可存在多种实现方案，在以下多种实现方案中终端设备可以不向基站上报编码速率调整能力指示信息，也可以上报编码速率调整能力指示信息。
实现方式一，基站向终端设备发送跨级目标编码速率，而终端设备不支持跨级速率调整，则终端设备可进行多次调整，每次调整一级速率，直至将当前编码速率调整至跨级目标编码速率为止。
比如，编码速率集中支持5个编码速率，按大小排序依次为编码速率1、编码速率2、编码速率3、编码速率4和编码速率5。假设当前编码速率为编码速率2，则跨级目标编码速率为编码速率5，则终端设备可以进行如下操作：先将当前编码速率从编码速率2调整至编码速率3，再将当前编码速率从编码速率3调整至编码速率4，再将当前编码速率从编码速率4调整至编码速率5。
实现方式二，基站向终端设备发送跨级目标编码速率，而终端设备不支持跨级速率调 整，则终端设备可调整一级速率，基站发现终端设备未调整至跨级目标编码速率，则基站经过预设时长后可再次下发跨级目标编码速率，终端设备再调整一级速率，如此循环，直至终端设备将编码速率调整至跨级目标编码速率为止。基站发现终端设备未调整至跨级目标编码速率具体来说可通过多种方式，比如基站检测终端设备调整后的编码速率，或者终端设备调整编码速率之后，将调整后的编码速率上报给基站。基站经过预设时长后可再次下发跨级目标编码速率，具体来说，预设时长可以为基站侧预先设置的一个值，可通过定时器来设置，如果该预设时长时间较长，基站再次下发跨级目标编码速率时也可以根据最新的网络状况信息重新确定一个新的跨级目标编码速率。
比如，编码速率集中支持5个编码速率，按大小排序依次为编码速率1、编码速率2、编码速率3、编码速率4和编码速率5。假设当前编码速率为编码速率2，则跨级目标编码速率为编码速率5，则终端设备接收到跨级目标编码速率之后将当前编码速率从编码速率2调整至编码速率3。基站经检测或者通过接收终端设备上报的当前编码速率，发现终端设备并未将编码速率调整至编码速率5，则再次下发跨级目标编码速率，此次下发的跨级目标编码速率仍为编码速率5，终端设备接收到跨级目标编码速率之后将当前编码速率从编码速率3调整至编码速率4。基站经检测或者通过接收终端设备上报的当前编码速率，发现终端设备并未将编码速率调整至编码速率5，则再次下发跨级目标编码速率，此次下发的跨级目标编码速率仍为编码速率5，终端设备接收到跨级目标编码速率之后将当前编码速率从编码速率4调整至编码速率5。
再比如，编码速率集中支持5个编码速率，按大小排序依次为编码速率1、编码速率2、编码速率3、编码速率4和编码速率5。假设当前编码速率为编码速率2，则跨级目标编码速率为编码速率5，则终端设备接收到跨级目标编码速率之后将当前编码速率从编码速率2调整至编码速率3。基站经检测或者通过接收终端设备上报的当前编码速率，发现终端设备并未将编码速率调整至编码速率5，则根据最新的网络状况信息再次确定一个新的跨级目标编码速率，该最新的跨级目标编码速率可以与上一次的跨级目标编码速率相同或不同，比如新的跨级目标编码速率为4，则终端设备接收到跨级目标编码速率之后将当前编码速率从编码速率3调整至编码速率4。
实现方式三，基站向终端设备发送跨级目标编码速率，而终端设备不支持跨级速率调整，则终端设备调整一级速率。
比如，比如编码速率集中支持5个编码速率，按大小排序依次为编码速率1、编码速率2、编码速率3、编码速率4和编码速率5。假设当前编码速率为编码速率2，则跨级目标编码速率为编码速率5，则终端设备接收到跨级目标编码速率之后将当前编码速率从编码速率2调整至编码速率3。基站向终端设备发送跨级目标编码速率，而终端设备不支持跨级速率调整，若跨级目标编码速率大于当前编码速率，则终端设备将当前编码速率调高一级速率，若跨级目标编码速率小于当前编码速率，则终端设备将当前编码速率调低一级速率。

可选地，本申请实施例提供了一种包含指令的计算机程序产品，当其在计算机上运行时，使得计算机执行上述终端设备的所实现的编码速率的调整方案的任一种方法。
在终端设备的通信过程中，如果终端设备不向基站上报端到端时延或时延余量，基站无法知道实际通信的时延余量，因此也无法根据时延余量进行空口操作的调整，导致空口的覆盖率较低。基于此，本申请实施例提供了一种通信时延的处理方案，在该方案中，终端设备向基站上报时延参数，基站可根据时延参数确定出时延余量，进而根据该时延余量进行空口操作的调整，从而提高空口的覆盖率。进一步，本申请实施例中，还限定了终端设备向基站上报时延参数的条件，如此，可避免终端设备频繁向基站上报时延参数，减少终端设备向基站上报时延参数的数量，减少了基站处理信令的开销，且也减少了对终端设备对应的参数进行频繁调整的问题，下面对本申请实施例进行详细介绍。
图7示例性提供一种通信时延的处理方法的流程示意图，如图7所示，方法包括：
步骤701，基站为终端设备配置第一门限和第二门限，第一门限小于第二门限；终端设备接收基站下发的第一门限和第二门限，第一门限小于第二门限；
步骤702，终端设备获取终端设备的链路质量；
步骤703，当链路质量高于第一门限或链路质量低于第二门限时，终端设备向基站上报时延参数；其中，时延参数用于使基站根据时延参数调整空口的非连续接收(cell-discontinuous reception，CDRX)周期或空口数据包的重传次数；基站从终端设备接收时延参数，其中，时延参数是终端设备在链路质量高于第一门限或链路质量低于第二门限时上报的；
步骤704，基站根据时延参数调整空口的CDRX周期或空口数据包的重传次数。
上述步骤701中基站可通过多种方式为终端设备配置第一门限和第二门限，比如基站和终端设备通过提前约定的方式约定第一门限和第二门限；或者基站通过下发信令向终端设备发送第一门限和第二门限，从而实现在终端设备上配置第一门限和第二门限的目的。一种可能的实施方式为，基站先通过无线资源控制(Radio Resource Control，RRC)信令或者媒体接入控制元素(Medium Access Control Control Element，MAC CE)信令给终端设备配置第一门限和第二门限，若需要对配置的第一门限和第二门限进行更新的话，则重新 通过RRC信令或者MAC CE信令给UE配置。
可选地，基站可单独发送一条信令用于向终端设备发送第一门限和第二门限，基站也可将第一门限和第二门限携带于其它信令上，比如将第一门限和第二门限携带于基站向终端设备发送的RRC信令。或者，第一门限和第二门限还可以携带在基站向终端设备发送的MAC CE信令中发送。
本申请实施例中MAC CE是标准36.321中定义的MAC层的控制面消息。MAC CE信令可包括包括缓冲区状态报告(Buffer Status Report，BSR)，用于使终端设备上报上行数据量的信令；功率余量报告(Power Headroom Report，PHR)，用于使终端设备上报功率余量的信令等等，不同功能定义的MAC CE信令不同，所以本申请实施例中也可能是新定义一个MAC CE信令用于承载第一门限和第二门限。
本申请实施例中的第一门限和第二门限，可根据经验来确定，比如，基站可根据链路质量来确定第一门限和第二门限，但不限于此。也就是说，当终端设备的链路质量处于第一门限和第二门限之间的情况下，终端设备无需向基站上报自己的时延参数，终端设备可以维持自己当前的时延参数，如此，减少了终端设备向基站上报时延参数的数量，避免终端设备频繁向基站上报时延参数的问题，进一步，本申请实施例中减少了基站处理信令的开销，且也减少了对终端设备对应的参数进行频繁调整的问题。
上述步骤702中，终端设备的链路质量可用能够表示链路质量的参数来表示，比如可为信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)，也可以是参考信号接收功率(Reference Signal Receiving Power,RSRP)。
本申请中提供一种可选地的实施方案，时延参数为端到端的通信时延。终端设备向基站上报时延参数，包括：终端设备获取端到端的通信时延；终端设备向基站上报端到端的通信时延。本申请实施例中端到端的通信时延具体是指信令从进行通信的一个终端设备传输至另一个终端设备所花费的时间。
可选地，端到端的通信时延指的是一个数据包从发送端发送开始计时，到接收端收到总共经历的时长。图8示例性示出了端到端的通信时延的结构示意图，如图8所示，按照现有机制的计算，作为发送端的终端设备在发射信号应答器(Launch Signal Responder,LSR)时刻发送了一个实时传输控制协议((Real Time Control Protocol，RTCP)包，如图8中所示的SRi数据包，作为接收端的终端设备收到该RTCP包后在经历了DLSR时长后向作为发送端的终端设备发送了一个RTCP包进行反馈，如图8中所示的SRj反馈包，作为发送端的终端设备在A时刻接收到作为接收端的终端设备反馈的RTCP包，这样端到端的通信时延计算就按公式(1)所示：
E2E delay＝(time A-time LSR-DLSR)/2……公式(1)
在公式(1)中，E2E delay为作为发送端的终端设备的端到端的通信时延；time A为A时刻，time LSR为LSR时刻，DLSR为DLSR时长。
在公式(1)中，LSR时刻和DLSR时长这两个值是携带在SRj反馈包中的，作为发送端的终端设备在收到SRj反馈包时可以获得该两个值，进而作为发送端的终端设备可以根据公式(1)可以算出实际的端到端时延。
在时延参数为端到端的通信时延的情况下，可选地，基站根据时延参数调整空口的CDRX周期或空口数据包的重传次数，包括：基站根据端到端的通信时延和预设的通信时延，确定端到端的通信时延余量。可选地，当端到端的通信时延余量大于零时，基站增加 空口的CDRX周期；或者当端到端的通信时延余量大于零时，基站增加空口数据包的重传次数。可选地，当端到端的通信时延余量不大于零时，基站减少空口的CDRX周期；或者当端到端的通信时延余量不大于零时，基站减少空口数据包的重传次数。
可选地，本申请实施例中，预设的通信时延可为运营商允许的通信时延，比如可为200ms。可选地，端到端的通信时延余量(英文可称为delay budget)可为预设的通信时延和端到端的通信时延的差值。
本申请中提供另一种可能的实施方案，终端设备向基站上报时延参数，包括：终端设备获取端到端的通信时延；终端设备根据端到端的通信时延和预设的通信时延，确定端到端的通信时延余量；终端设备向基站上报端到端的通信时延余量。
在时延参数为端到端的通信时延余量的情况下，可选地，端到端的通信时延余量为预设的通信时延和端到端的通信时延的差值，可为终端设备根据预设的通信时延和端到端的通信时延的差值确定出的端到端的通信时延余量。可选地，基站根据时延参数调整空口的CDRX周期或空口数据包的重传次数，包括：可选地，当端到端的通信时延余量大于零时，基站增加空口的CDRX周期；或者当端到端的通信时延余量大于零时，基站增加空口数据包的重传次数。可选地，当端到端的通信时延余量不大于零时，基站减少空口的CDRX周期；或者当端到端的通信时延余量不大于零时，基站减少空口数据包的重传次数。
本申请实施例中，当端到端的通信时延余量大于零时，也就是说，预设的通信时延大于终端设备的端到端的通信时延，基站增加空口的CDRX周期或增加空口数据包的重传次数。可选地，终端设备可向基站上包括链路质量，或者，基站在接收到终端设备上报的时延参数的情况下，基站对终端设备的链路质量进行检测，在链路质量高于第一门限的情况下，也就是说在无线环境较优的情况下，基站可增加空口的CDRX周期，从而帮助终端设备节能。可选地，在链路质量低于第二门限的情况下，也就是说在无线环境较差的情况下，基站可增加空口数据包的重传次数，从而提高终端设备的空口数据传输的可靠性。
本申请实施例中，当端到端的通信时延余量不大于零时，也就是说，预设的通信时延不大于终端设备的端到端的通信时延，基站减少空口的CDRX周期或增加空口数据包的重传次数。可选地，终端设备可向基站上包括链路质量，或者，基站在接收到终端设备上报的时延参数的情况下，基站对终端设备的链路质量进行检测，在链路质量高于第一门限，也就是说在无线环境较优的情况下，基站可减少空口的CDRX周期，从而可减少终端设备的端到端的通信时延。可选地，在链路质量低于第二门限的情况下，也就是说在无线环境较差的情况下，基站可减少空口数据包的重传次数，从而可减少终端设备的端到端的通信时延。
本申请实施例中的空口的CDRX周期可为基站周期性向终端设备发送数据包的周期。本申请实施例中的空口数据包的重传次数可为基站向终端设备重传数据包的次数。
例如：基站已经给UE配置了空口的CDRX周期为20ms，如果此时UE链路质量高于第一门限并上报了一个时延参数，基站根据该时延参数调整空口的CDRX周期为60ms，以帮助UE省电。或者基站给UE配置的空口最大重传次数为5，如果此时UE链路质量低于第二门限并上报了一个时延参数，基站根据该时延参数调整空口的最大重传次数为2。等等，这些都只是一个示例。
本申请实施例中，基站增加空口的CDRX周期，有多种方式，比如说预设多个空口的CDRX周期，当基站需要增加空口的CDRX周期时，基站从预设的多个空口的CDRX周 期里选择一个比当前的空口的CDRX周期大的空口的CDRX周期，将其更新为当前的空口的CDRX周期。再或者，预设空口的CDRX周期的调整步长，比如每次将步长设置为10毫秒(ms)，则当基站需要增加空口的CDRX周期时，基站将当前的空口的CDRX周期增加10ms。再或者，基站根据当前UE上报的时延参数来判断空口可放宽的时延，并将该时延设置为空口的CDRX周期，例如：UE上报的时延参数为100ms，当前空口的CDRX周期配置为60ms，则基站将空口的CDRX周期更新为100ms。
本申请实施例中，基站减少空口的CDRX周期，有多种方式，比如说预设多个空口的CDRX周期，当基站需要减少空口的CDRX周期时，基站从预设的多个空口的CDRX周期里选择一个比当前的空口的CDRX周期小的CSRX周期，将其更新为当前的空口的CDRX周期。再或者，预设空口的CDRX周期的调整步长，比如每次将步长设置为10毫秒(ms)，则当基站需要减少空口的CDRX周期时，基站将当前的空口的CDRX周期减少10ms。
本申请实施例中，基站增加空口数据包的重传次数，有多种方式，比如说预设多个空口数据包的重传次数，当基站需要增加空口数据包的重传次数时，基站从预设的多个空口数据包的重传次数里选择一个比当前的空口数据包的重传次数大的空口数据包的重传次数，将其更新为当前的空口数据包的重传次数。再或者，预设空口数据包的重传次数的调整步长，比如每次将步长设置为1次，则当基站需要增加空口数据包的重传次数时，基站将当前的空口数据包的重传次数增加1次。再或者，基站根据当前UE上报的时延参数来判断空口可放宽的时延，并设置对应的重传次数，例如：UE上报的时延参数为100ms，当前空口重传次数为5次，假如重传一次需要的时间为8ms，则基站最多可以将空口重传次数增加到12(100ms与8ms的比值)次。
本申请实施例中，基站减少空口数据包的重传次数，有多种方式，比如说预设多个空口数据包的重传次数，当基站需要减少空口数据包的重传次数时，基站从预设的多个空口数据包的重传次数里选择一个比当前的空口数据包的重传次数小的空口数据包的重传次数，将其更新为当前的空口数据包的重传次数。再或者，预设空口数据包的重传次数的调整步长，比如每次将步长设置为1次，则当基站需要减少空口数据包的重传次数时，基站将当前的空口数据包的重传次数减少1次。
