Description

5G NSA的上行通信控制方法、装置、终端及计算机可读存储介质 技术领域
本公开涉及但不限于通信技术领域。
背景技术
在运营商组织的5G(5th Generation Mobile Networks，第五代移动通信技术)NSA(Non-Stand Alone，非独立组网)大规模外场试验中，发现终端在采用了NSA技术时，由于终端上行发射总功率被LTE(Long Term Evolution,长期演进)无线制式网络和NR(New Radio，新空口)无线制式网络共享了，导致在通过其中一个无线制式网络进行上行通信时会出现性能明显变差的现象。例如，5G NSA的终端在进行高清语音和视频通话的时候通过LTE无线制式网络进行上行通信，但是由于此时一部分功率给了5G NR无线制式网络侧，导致在同一个地点，且同一时间下5G终端的LTE无线制式网络功率最大只能发射到20dBm。而相同的纯LTE无线制式网络传统的终端则可以发射到23dBm，相差的3dBm转换成实际上行通信数据传输效率值就是2倍的关系。也就是说相关的5G NSA终端的LTE侧的最大发射功率的上行通信传输效率值只能达到纯4G(4th Generation Mobile Communication Technology，第四代移动通信技术)终端的一半，而5G NSA终端的NR无线制式网络则被闲置。
同时，实际测试表明，在相同LTE信号较差的地点，纯4G终端在使用LTE无线制式网络进行通话时没有出现掉话或者无法呼通的情况时，采用NSA技术的5G NSA终端在使用LTE无线制式网络进行通话时就会出现无法呼通或者掉话现象，但此时NR无线制式网络信号较好，可以支持良好的通话，此时无法自动切换到NR无线制式网络，导致系统资源浪费，同时影响用户体验。亟需一种通信控制方法来保证5G NSA终端在通过一侧网络进行上行通信时，可以根据需求自动切换到另一侧网络。
发明内容
本公开实施例的一个方面提供一种5G NSA的上行通信控制方法，包括：在当前同时接入第一无线制式网络和第二无线制式网络，且采用第一无线制式网络进行上行通信的过程中，对当前的上行通信进行监测；以及，响应于确定监测结果满足预设切换条件，切换为至少采用第二无线制式网络进行上行通信。
本公开实施例的另一方面提供一种5G NSA的上行通信控制装置，包括：监测模块，被配置为在当前同时接入第一无线制式网络和第二无线制式网络，且采用第一无线制式网络进行上行通信的过程中，对当前的上行通信进行监测；以及，切换模块，被配置为响应于确定监测结果满足预设切换条件，切换为至少采用第二无线制式网络进行上行通信。
本公开实施例的又一方面提供一种5G NSA终端，该5G NSA终端接入第一无线制式网络和第二无线制式网络，并包括处理器、存储器及通信总线；其中：通信总线被配置为实现处理器和存储器之间的通信连接；以及，处理器被配置为执行存储器中存储的一个或者多个程序,以实现上述的5G NSA的上行通信控制方法的至少一个步骤。
公开实施例的再一方面提供一种计算机可读存储介质，其上存储有一个或者多个程序，该一个或者多个程序可被一个或者多个处理器执行，以实现上述的5G NSA的上行通信控制方法的至少一个步骤。
本公开其他特征和相应的有益效果在说明书的后面部分进行阐述说明，且应当理解，至少部分有益效果从本公开说明书中的记载变的显而易见。

具体实施方式
为了使本公开的目的、技术方案及优点更加清楚明白，下面通过具体实施方式结合附图对本公开实施例作进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本公开，并不用于限定本公开。

根据本公开提供的实施例，第一无线制式网络和第二无线制式网络分别为不同的网络，5G NSA终端分别接入到了第一无线制式网络和第二无线制式网络对应的小区。可以理解的是，相关技术中5G NSA能够通过不同方法接入第一无线制式网络和第二无线制式网络对应的小区，如何接入第一无线制式网络和第二无线制式网络分别对应的小区不是本公开的重点，在此不再一一赘述。
可以理解的是，采用第一无线制式网络进行上行通信的过程，具体可以为，在当前同时接入第一无线制式网络和第二无线制式网络，且存在业务仅采用第一无线制式网络进行上行通信的过程。例如，终端进行高清语音通话业务时仅采用LTE无线制式网络进行高清语音通话业务的上行通信，也即该高清语音通话业务并没有用到第二无线制式网络，此过程则为采用第一无线制式网络进行上行通信。

根据本公开提供的实施例，上述预设类型业务包括但不限于多媒体业务；多媒体业务包括但不限于以下至少一种业务：高清语音通话业务、高清视频通话业务、游戏业务、下载业务等。例如，监测到当前上行通信所承载的业务为高清语音通话业务时，则判定监测结果满足预设切换条件。可以理解的是，本公开实施例并不限定预设类型业务为多媒体业务，相关设计人员可以根据需求灵活的设置预设类型业务。
根据本公开提供的实施例，上述通信指标包括但不限于以下指标中的至少一个:误块率(Block Error Rate，BLER)、传输时延值Delay、吞吐率等。例如，监测到当前上行通信的吞吐率达到预设阈值时，则判定监测结果满足预设切换条件。可以理解的是，本公开实施例并不限定通信指标为以上指标，相关设计人员可以根据需求灵活的设置通信指标。
可以理解的是，预设切换条件还可以包括：当前上行通信所承载的业务为预设类型业务，且当前上行通信的通信指标低于预设阈值。例如，监测到当前上行通信所承载的业务为高清视频通话业务，且当前上行通信的误块率达到预设阈值时，则判定监测结果满足预设切换条件；若监测到当前上行通信所承载的业务为高清视频通话业务，且当前上行通信的误块率未达到预设阈值时，则判定监测结果未满足预设切换条件。例如，高清语音通话业务的误块率预设阈值可以设置为7％,当第一无线制式网络进行上行通信承载高清语音通话业务时，且第一无线制式网络的上行通信的误块率高于7％七时，则判定监测结 果满足预设切换条件。可以理解的是，在一些实施实例中，不同业务的通信指标可以对应不同的预设阈值；如高清语音通话业务的误块率预设阈值可以设置为7％，高清视频通话业务的误块率预设阈值可以设置为5％。在一些实施例中，不同业务的通信指标也可使用相同的预设阈值。
根据本公开提供的实施例，切换条件包括当前上行通信的通信指标达到预设阈值，当检测结果为满足预设切换条件时，在切换为至少采用第二无线制式网络进行上行通信之前，该方法还可包括：判断第一无线制式网络的上行发射功率是否能够上调；若否，切换为至少采用第二无线制式网络进行上行通信；若是，则上调第一无线制式网络的上行发射功率。
可以理解的是，第一无线制式网络与第二无线制式网络共享终端的上行发射总功率；例如终端的上行发射总功率为23dbm，第一无线制式网络的上行发射功率为20dbm，则此时第二无线制式网络的上行发射功率为23dbm-20dbm＝3dbm。可以理解的是，判断第一无线制式网络的上行发射功率是否能够上调，若否，切换为至少采用采用第二无线制式网络进行上行通信；也即当第一无线制式网路的上行发射功率不能够上调时，则切换为至少采用第二无线制式网络进行上行通信。不能够上调第一无线制式网路的上行发射功率包括但不限于以下两种场景中的任一种场景。
在第一种场景中，当第一无线制式网络的上行发射功率达到预设最大阈值时，则判定第一无线制式网络的上行发射功率不能够上调。例如，当前第一天线制式网络的上行发射功率为20dbm，预设最大阈值为20dbm，则此时判定第一无线制式网络的上行发射功率不能够上调。
在第二种场景中，当第一无线制式网络的上行发射功率可调余量小于单次第一无线网络制式上行发射功率调整量dp上行发射功率调整量dp时，则判定一无线制式网络的上行发射功率不能够上调。例如，第一无线制式网络的上行发射功率最大阈值为20dbm，预设dp＝2dbm，当前第一天线制式网络的上行发射功率为15dbm，此时 第一无线制式网络的上行发射功率可调余量PH_TH＝20-15＝5dbm，此时PH_TH大于dp，则判定第一无线制式网络的上行发射功率能够上调；当PH_TH小于dp时，则判定第一无线制式网络的上行发射功率不能够上调。
根据本公开提供的本实施例，切换为至少采用第二无线制式网络进行上行通信可包括以下方式一和方式二中的任一个。
在方式一中，切换到第二无线制式网络，采用第二无线制式网络进行上行通信。
在方式二中，对第一无线制式网络承载的数据进行分裂，通过第一无线制式网络和第二无线制式网络发送分裂后的数据。
可以理解的是，上述方式二可包括：对第一无线制式网络承载的数据进行分裂，通过第一无线制式网络和第二无线制式网络同时发送相同的分裂后的数据。如图2所示，其为本公开实施例提供的第一无线制式网络与第二无线制式网络发送上行数据的示意图。第一无线制式网络和第二无线制式网络同时发送第1个数据包，当接收端确认接收到第一无线制式网络或第二无线制式网络任一无线制式网络发送的第1个数据包后，第一无线制式网络和第二无线制式网络同时发送第2个数据包，当接收端确认接收到第一无线制式网络或第二无线制式网络任一无线制式网络发送的第2个数据包后，第一无线制式网络和第二无线制式网络重复上述步骤成功发送了第3个数据包，此时第一无线制式网络和第二无线制式网络同时发送第4个数据包，接收端确认未接收到第一无线制式网络和第二无线制式网络任一网络发送的第4个数据包时，第一无线制式网络和第二无线制式网络同时重新发送第4个数据包，接收端确认接收到第一无线制式网络发送的第4个数据包后，第一无线制式网络和第二无线制式网络继续发送剩下的数据包。
根据本公开提供的本实施例，第一无线制式网络可为LTE无线制式网络，第二无线制式网络可为NR无线制式网络。本公开实施例并不限定第一无线制式网络为LTE无线制式网络，也不限定第二无线制式网络为NR无线制式网络。也即第一无线制式网络可以为LTE无 线制式网络或NR无线制式网络等无线制式网络，第二无线制式网络也可以为LTE无线制式网络或NR无线制式网络等无线制式网络，可以理解的是，第一制式网络与第二制式网络为不同制式网络。
根据本公开实施例提供的5G NSA的上行通信控制方法，通过在当前同时接入第一无线制式网络和第二无线制式网络，且采用第一无线制式网络进行上行通信的过程中，对当前的上行通信进行监测，且当监测结果满足预设切换条件时，切换为至少采用第二无线制式网络进行上行通信，解决了5G NSA终端在通过任一无线制式网络进行上行通信时，无法根据需求自动切换到另一无线制式网络，影响用户体验的问题。在通过任一侧无线制式网络进行上行通信时，若该任一侧无线制式网络传输性能差，可靠性、稳定性低，无法满足用户需求，此时可以自动切换到至少采用与该任一侧无线制式网络不同的另一侧无线制式网络进行上行通信，提高了上行通信的网络传输性能、可靠性及稳定性，提升了用户体验。
为了更好地理解本公开，本公开实施例提供一个较为具体的例子以对5G NSA的上行通信控制方法进行说明，如图3所示，其为本公开实施例提供的5G NSA的上行通信控制方法的另一种流程示意图，该5G NSA的上行通信控制方法可包括步骤S301，以及步骤S302或步骤S303。
在步骤S301中，发起高清语音通话(Voice over Long-Term Evolution，VOLTE)。
此时用户使用具有5G NSA功能的终端，且该终端已经注册了到了5G NSA架构的网络上，也即注册到了LTE与NR网络之中。
根据本公开提供的实施例，当检测到终端通过LTE无线制式网络发起了高清语音通话时，终端开始以监测统计时间dt＝1秒为颗粒度来监测上行数据包的传输效率，具体可以为监测上行数据包中的误块率，监测方法可以采用已有的技术(例如监控DCI里面NDI翻转情况和重传调度情况，计算得到错误的包数，除以总的包数之后就可以得到误块率)。需要说明的是，监控方法采用现有技术，可以采用各种方法监控上行数据的误块率或其他可以反映传输上行数据的参数， 具体的如何监测传输上行数据的参数并不是本公开关注的重点，在此则不在赘述。
在步骤S302中，当高清语音通话数据包的误块率达到预设阈值时，上调LTE无线制式网络的发射功率。
根据本公开提供的实施例，为了便于理解，设定误块率的预设阈值可为7％。可以理解的是，本公开实施例并不限定误块率的预设阈值，可以根据实际使用环境，以及具体业务设置误块率的预设阈值。
可以理解的是，最开始终端处于小区中心附近，上行和下行信道质量比较好，此时测量到的5dt时间误块率的值，也即5s的误块率的值分别是0.5％、1.3％、0.9％、1.4％，以及2％，此时误块率的值均满足误块率小于预设阈值7％的条件，所以此时无需进行任何额外操作。随着外部环境的改变，如用户的移动，使得终端从小区中心逐步来到小区边缘，也即终端LTE网络发射效率逐渐减弱，此时测量到的5dt时间误块率，也即5s的误块率值分别是2％、5％、7.1％、8.5％，以及9.2％,即后三秒的误块率大于预设阈值7％，则需要上调LTE的发射功率。
根据本公开提供的实施例，若此时终端的LTE网络侧发射功率值P＝12dBm，而LTE网络侧最大允许发射的功率值是Pmax＝20dBm，功率余量阈值PH_TH＝2dBm，那么此时功率余量PH＝Pmax-P＝8dBm，此时PH大于功率余量阈值PH_TH，则此时可以提升发射功率P。可以理解的是，预设发射功率调整量dP的值不受限定，在本实例中，预设发射功率调整量dP＝2dBm，调整发射功率后LTE网络侧的发射功率达到P＝12dBm+dP＝14dBm；若此时监测到误块率的5s值到达7.4％、8.5％、8.3％，以及9.66％，此时5dt时间内的误块率大于预设阈值7％，则继续提升dP的功率，P＝14dBm+dP＝16dBm；若此时监测到误块率的5s值到达1％、2％、1％，以及1.5％，则此时误块率小于预设阈值7％，误块率相对足够低，停止上行功率的调整；但是随着用户继续往小区边缘走，过了一段时间后，误块率的监测到的值为7％、12％、15％，以及14％，此时误块率大于预设阈值7％，假设此时终端的上行功率P＝19dBm，PH＝20dBm-19dBm＝1dBm，PH<PH_TH，则说明无法提升LTE 网络侧的发射功率。
在步骤S303中，当高清语音通话数据包的误块率达到预设阈值且无法上调LTE网络的发射功率时，通过NR网络并行发送高清语音通话数据包。
根据本公开提供的实施例，终端发送特定的标识位，请求NR网络侧对于当前高清语音通话所在的数据无线承载DRB进行上行分流。NR网络侧发送确认同意请求消息，此时终端针对LTE网络侧和NR网络侧都给予终端上行资源分配授权。终端监测到LTE和NR侧都有上行资源授权的时候，将同时通过LTE网络侧和NR网络侧的上行资源发送第n个数据包。可以理解的是，服务器端同时针对在LTE网络侧和NR网络侧上的第N个数据包进行解码，只要有任一网络侧的其中一个第N个数据包解码成功，则服务器端向终端指示传送成功标识，则终端继续发送第N+1个数据包。
可以理解的是，若服务器在LTE和NR侧都没有收到或成功解码第N个数据包，则服务器端向终端指示未成功传送标识，并且指示终端重传时LTE和NR侧的上行资源授权，终端根据重新指示的上行资源授权，重新传输第N包数据，直到接到到传送成功标识。
根据本公开实施例提供的5G NSA的上行通信控制方法，获取第一无线网络制式中传输上行数据的传输效率，当传输效率达到到预设阈值时，上调第一无线网络制式的发射功率；当传输效率达到预设阈值且无法上调第一无线网络制式的发射功率时，切换到采用第二无线网络制式进行上行通信；显著的提升了处于LTE覆盖边缘的5G NSA终端的电话呼通率，以及显著降低由于上行功率不足导致的5G NSA终端出现的语音卡顿和单通现象；同时实现复杂度低，不会大幅度增加手机的功耗和实现成本，在充分利用现有资源的同时，提升了用户体验。
本公开实施例还提供一种5G NSA的上行通信控制装置，参见图4所示，其为本公开实施例提供的5G NSA的上行通信控制装置的一种结构示意图。该装置可包括监测模块41和切换模块42。
监测模块41，可被配置为在当前同时接入第一无线制式网络和 第二无线制式网络，且采用第一无线制式网络进行上行通信的过程中，对当前的上行通信进行监测。
