一种调控终端温度的方法、装置、终端和存储介质
相关申请的交叉引用
本申请基于申请号为202011519160.9、申请日为2020年12月21日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此以引入方式并入本申请。
技术领域
本申请涉及终端设备技术领域，特别涉及一种调控终端温度的方法、装置、终端和存储介质。
背景技术
目前，对于终端发热的问题，在软件处理上，会采用热缓解(Thermal Mitigation)的方式，热缓解通常是先设定几个门限值，当温度达到一定的门限值后，移除部分下行辅小区组(Secondary Cell Group，SCG)，最后把整个网路连线移除，实现快速降温。
然而，采用上述方式，会造成数据吞吐量(data throughput)快速降低，会造成资料传输上的不稳定，且使用者在应用上感受不佳。因为无法在区间做下行微调数据吞吐量的动作，所以，当温度达到门限值时，移除SCG也来不及降温，最后为了降温只能中断整个5G非独立组网(Non-Standalone，NSA)或者4G长期演进(Long Term Evolution，LTE)网路的连线，会造成有一段时间没有数据网路可用。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，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。
如图1所示，图1是本申请实施例的终端的应用环境图，应用环境包括用户设备(User Equipment，UE)100和基站200。示例性的，基站200与UE 100之间例如可以通过建立无线资源控制(Radio Resource Control，RRC)连接，以在例如第四代移动通信技术(the 4th generation mobile communication technology，4G)的演进分组系统(Evolved Packet System，EPS)中建立连接。示例性的，在4G网络中，基站200可以是演进型基站(eNB)，当然，在其他网络中，基站200也可以是其他类型的基站，例如5G网络中的gNB，本实施例中对此不做限定。UE100在与基站200通信时，如上行通信或下行通信，若数据吞吐量的速度较快，会引起终端发热的问题。
针对终端发热的问题，软件处理采用热缓解(Thermal Mitigation)的方式，越高的下行资料速度会造成越高的热量。因为越高的下行资料速度，会需要越高的Baseband Processor(基频芯片/数据机芯片)的运算速度，然后才能来得及处理快速下载的资料，而Baseband Processor(基频芯片/数据机芯片)的运算速度越高，运算量就越大，会消耗的功率就越多，因此，产生了更高的热量。
参考图2和图3中分别为Sub-6GHz(Sub-6GHz是指频率低于6GHz 的电磁波)及毫米波(mmWave)两种频谱在不同下行(DL)速度下，各硬件模块的功率消耗及总体温度变化，从芯片商提供的功率分布信息可以了解到，主要消耗功率(产生热量)的模块为基带处理器(Baseband Processor，BP)(或称为调制解调器(modem)中央处理器(Central Processing Unit，CPU)、数据机芯片)，而此就是因为处理下行资料运算所产生的功率消耗(产生的热量)，Modem CPU的下行速度越高，产生的热量越高。因此，考虑将温度变化曲线划分为多个温度区间，限制CQI/RI上报来快速调变下行速度，进而达到热和缓目的。
以温度变化曲线中的温度上升曲线为例，如图4所示，图4为本申请实施例中终端下行速度及温升的曲线图，X轴表示时间，Y轴表示温度，可知在相同的通讯系统下，以5G为例，若UE可以快速微调下行数据的速度，则可以在温度到达需要中断SCG前，就把温度降低，且让下行数据吞吐量(data throughput)的变化较为平缓。
图5示意性的示出了终端的硬件结构，如图5所示，终端100包括存储器11和处理器12，处理器12连接存储器11。本领域技术人员可以理解，图5所示的结构并不构成对终端的限定，终端可以包括比图示更多或者更少的部件，或者组合某些部件，或者拆分某些部件，或者不同的部件布置。
其中，存储器11作为一种非易失性计算机可读存储介质，可用于存储非易失性软件程序、非易失性计算机可执行程序以及模块。存储器11可以包括存储程序区和存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需要的应用程序；存储数据区可存储根据终端的使用所创建的数据等。此外，存储器11可以包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件、闪存器件、或其他非易失性固态存储器件。在一些实施例中，存储器11可选包括相对于处理器12远程设置的存储器，这些远程存储器可以通过网络连接至终端。上述网络的实 例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
处理器12是终端的控制中心，利用各种接口和线路连接整个终端的各个部分，通过运行或执行存储在存储器11内的软件程序和/或模块，以及调用存储在存储器11内的数据，执行终端的各种功能和处理数据，从而对终端进行整体监控，例如实现本申请任一实施例所述的调控终端温度的方法。
其中，处理器12可以为一个或多个，图5中以一个处理器12为例。处理器12和存储器11可以通过总线或者其他方式连接，图5中以通过总线连接为例。处理器12可包括CPU、数字信号处理器(Digital Signal Processor，DSP)、专用集成电路(Application Specific Integrated Circuit，ASIC)、控制器、现场可编程门阵列(Field-Programmable Gate Array，FPGA)设备等。处理器12还可以被实现为计算设备的组合，例如，DSP与微处理器的组合、多个微处理器、结合DSP核心的一个或多个微处理器、或者任何其它此类配置。
本申请实施例提供的调控终端温度的方法，所述方法可以由终端100执行，具体的，在其中一些实施例中，所述方法可由处理器12执行。
图6为本申请实施例提供的调控终端温度的方法的流程示意图，如图6所示，所述方法包括：
101：获取终端的温度变化曲线，所述温度变化曲线至少包括两个相邻的温度区间。
通常，终端的下行速度会引起终端的温度变化。包括CPU温度等硬件模块温度。示例性的，可以初步统计终端的温度变化，得到终端的温度变化曲线，可以包括温升曲线和温降曲线，如图7所示，将温升曲线或温降曲线划分为4个温度区间，分别为T1区间、T2区间、T3区间和T4区间，当然，本实施例中不局限于4个温度区间，可以是更多或更少的温度区间， 但是至少是2个温度区间。
102：检测所述终端的实时温度值。
103：根据所述温度变化曲线，确定所述实时温度值所在的温度区间。
本实施例中，实时监测终端的温度值，即检测所述终端的实时温度值，且根据所述温度变化曲线，确定所述实时温度值所在的温度区间。
示例性的，本实施例可以在终端内部设置温度传感器，通过内部温度传感器实时监测终端的实时温度值，且温度传感器可以将实时温度值发送至终端的控制器。
并且，终端存储有温度变化曲线，通过获得温度传感器采集的实时温度值，对比温度变化曲线，从而确定当前的实时温度值处于温度变化曲线的具体温度区间。示例性的，在实时温度值不小于第一区间的最小温度值，且不大于第一区间的最大温度值时，确定实时温度值位于第一区间；在实时温度值不小于第二区间的最小温度值，且不大于第二区间的最大温度值时，确定实时温度值位于第二区间。比如，确定实时温度值位于第一区间T1，或者位于第二区间T2等等。
104：获取所述温度区间对应的CQI最大值和RI最大值。
CQI用于反映物理下行共享信道(Physical Downlink Shared Channel，PDSCH)的信道质量。示例性的，CQI中，用0～15来表示PDSCH的信道质量，0表示信道质量最差，15表示信道质量最好。
RI，用来指示PDSCH的有效的数据层数，用于通知eNB，UE现在可以支持的码字(Code Word，CW)数。示例性的，RI＝1，1CW；RI>1，2CW。
例如，温度区间包括第一区间T1区间和第二区间T2，以温升曲线为例，获取所述温度区间对应的CQI最大值和RI最大值，可以包括：若所述实时温度值位于所述第一区间，获取所述第一区间对应的CQI最大值和RI最大值。
105：将所述终端上报的最大CQI值限制在所述CQI最大值，且将所述终端上报的最大RI值限制在所述RI最大值，得到当前CQI值和当前RI值。
在其中一些实施例中，参照图7所示，若所述实时温度值位于所述第一区间(如T1区间)，将终端上报的最大CQI值限制在第一区间T1对应的CQI最大值(max_cqi_t1)，且将终端上报的最大RI值限制在第一区间对应的秩指示RI最大值(max_ri_t1)。
106：将所述当前CQI值和当前RI值发送至基站，以供所述基站根据所述当前CQI值和当前RI值提供所述终端的下行数据吞吐量。
在其中一些实施例中，在所述实时温度值位于所述第一区间的情况下，获取所述第一区间对应的CQI最大值和RI最大值；将第一CQI值和第一RI值发送至基站，以供所述基站根据所述第一CQI值和第一RI值提供所述终端的第一下行数据吞吐量；所述第一CQI值为所述终端上报的最大CQI值限制在所述第一区间对应的CQI最大值获得，所述第一RI值为所述终端上报的最大RI值限制在所述第一区间对应的RI最大值获得。
当上报的当前CQI值和当前RI值越大，则表示基站可以提供给终端的下行速度越快(速度值越大)，相反，若上报的当前CQI值或当前RI值越小，则表示基站可以提供给终端的下行速度越慢(速度值越小)。
在其中一些实施例中，在所述实时温度值维持在所述第一区间的情况下，则将第一CQI值和第一RI值发送至基站，以供所述基站根据所述第一CQI值和第一RI值维持所述终端的第一下行数据吞吐量。
需要说明的是，根据UE无线接入能力的规定，下行数据吞吐量(data throughput)主要是依据调制阶数(Modulation Order)及多入多出层(MIMO Layer)决定。
并且，根据目前的规定,网络侧会依据终端在信道状态信息(Channel  Status Information，CSI)信息反馈的CQI及RI值来决定下行的调制编码策略(modulation and code scheme，MCS)及MIMO Layer，反馈的CQI值或RI值越大，表示基站可以提供给终端的下行速度越快，相反的，若是反馈的CQI值或RI值越小，则可以提供给终端的下行速度相对较小。
因此，基于根据终端上报的当前CQI值和当前RI值，来决定下行MCS及MIMO Layer这个前提，实现网络侧对终端的下行数据吞吐量的平滑调整，从而使得终端达到降温效果。
在其中一些实施例中，在针对实时温度值位于第一区间T1时，基站根据第一CQI值和第一RI值进行终端的下行数据吞吐量调整后，若实时温度值持续上升，说明需要继续调整。
可选地，在所述实时温度值由位于所述第一区间上升至位于所述第二区间的情况下，则获取所述第二区间对应的CQI最大值和RI最大值。并且，将所述终端上报的最大CQI值限制在所述第二区间对应的CQI最大值(max_cqi_t2)，且将所述终端上报的最大RI值限制在所述第二区间RI最大值(max_ri_t2)，得到第二CQI值和第二RI值。
最后，将第二CQI值和第二RI值发送至基站，以供所述基站根据所述第二CQI值和第二RI值提供所述终端的第二下行数据吞吐量，其中，所述第二CQI值为所述终端上报的最大CQI值限制在所述第二区间对应的CQI最大值获得，所述第二RI值为所述终端上报的最大RI值限制在所述第二区间对应的RI最大值获得。
如图7中温升曲线所示，第一区间可以对应T1区间，第二区间可以对应T2区间。
由于实时温度值位于第一区间时的温度会明显小于位于第二区间的温度，因此，为了降低热量，基站下发至终端的所述第二下行数据吞吐量小于所述第一下行数据吞吐量，从而使得终端能够有效降温。
在其中一些实施例中，温度变化曲线还可以包括温降曲线，同样的，温降曲线也可以包括至少两个相邻的温度区间，比如，实时温度值由位于第一区间下降至位于第三区间，当实时温度值下降时，需要基站放宽下行数据吞吐量，从而有效提高下行速率。
在一些可选实施例中，所述温度区间还包括第三区间，所述第三区间的最大温度值小于所述第一区间的最小温度值；所述获取所述温度区间对应的CQI最大值和RI最大值，包括：在所述实时温度值由位于所述第一区间下降至位于所述第三区间的情况下，则获取所述第三区间对应的CQI最大值和RI最大值；
所述将所述当前CQI值和当前RI值发送至基站，以供所述基站根据所述当前CQI值和当前RI值提供所述终端的下行数据吞吐量，包括：将第三CQI值和第三RI值发送至基站，以供所述基站根据所述第三CQI值和第三RI值提供所述终端的第三下行数据吞吐量；所述第三CQI值为所述终端上报的最大CQI值限制在所述第三区间对应的CQI最大值获得，所述第三RI值为所述终端上报的最大RI值限制在所述第三区间对应的RI最大值获得。
示例性的，当终端的实时温度值下降到某个温度区间时，以同样的方式，调整CQI最大值(max-cqi值)及RI最大值(max-ri)值，从而使得基站提高终端的下行数据吞吐量。
可以理解的是，由于实时温度值下降，因此，基站下发至终端的所述第三下行数据吞吐量大于所述第一下行数据吞吐量，从而有效提高下行速率。
如图7所示，在温降曲线中，第一区间下降至位于所述第三区间中，第一区间可以对应T1区间，第三区间可以对应T2区间。
在其中一些可选实施方式中，每两个相邻的所述温度区间之间设有缓冲区，所述第一区间和第二区间之间的缓冲区为第一缓冲区，所述第一区 间与所述第三区间之间的缓冲区为第二缓冲区；所述方法还包括：在所述实时温度值由位于所述第一区间上升至位于所述第二区间的情况下，则在所述第一缓冲区，保持所述第一CQI值和第一RI值；在所述实时温度值由位于所述第一区间下降至位于所述第三区间的情况下，则在所述第二缓冲区，保持所述第一CQI值和第一RI值。
如图7所示，不管是温度变化曲线的温升曲线还是温降曲线，每相邻两个温度区间之间都会设有一个缓冲区(参照图中的间隔(Gap))，例如，在温升曲线，第一区间和第二区间之间的缓冲区为第一缓冲区(例如升温曲线中的温度区间T1和温度区间T2之间的Gap)，在温降曲线，第一区间与所述第三区间之间的缓冲区为第二缓冲区(例如降温曲线中的温度区间T1和温度区间T2之间的Gap)。
在所述实时温度值由位于所述第一区间上升至位于所述第二区间的情况下，则在所述第一缓冲区，保持所述第一CQI值和第一RI值，即保持上升前的第一CQI值和第一RI值一段时间，当实时温度值位于第二区间时，才会将终端上报的第一CQI值和第一RI值分别调整至第二区间对应的CQI最大值和RI最大值，从而避免下行数据时突然减少速率，防止短时间内来回设定max-cqi值及ri值造成下行数据吞吐量(data throughput)快速变化。
对应地，在所述实时温度值由位于所述第一区间下降至位于所述第三区间的情况下，则在所述第二缓冲区，保持所述第一CQI值和第一RI值，即保持下降前的第一CQI值和第一RI值，当实时温度值位于第三区间时，才会将终端上报的第一CQI值和第一RI值分别调整至第三区间对应的CQI最大值和RI最大值，从而避免下行数据时突然增加速率，防止短时间内来回设定max-cqi值及ri值造成下行数据吞吐量(data throughput)快速变化。
因此，设置缓冲区，可以避免下行速度来回跳动的乒乓效应，避免降温不久又马上升温。
可以理解的是，本申请实施例不局限于设置缓冲区以防止下行速度来回跳动的乒乓效应，也可以是其他方式，当然，即使没有缓冲区，由于设置多个温度区间，也同样可以在一定程度上防止下行速度来回跳动的乒乓效应，只是设置了缓冲区以后，使得调整更加平滑。
本申请实施例的调控终端温度的方法，将终端的温度变化曲线划分为至少两个温度区间，且检测终端的实时温度值，并且，确定实时温度值所在的温度区间，在确定实时温度值所在的温度区间后，获取所述温度区间对应的CQI最大值和RI最大值，将所述终端上报的最大CQI值限制在所述CQI最大值，且将所述终端上报的最大RI值限制在所述RI最大值，得到当前CQI值和当前RI值，然后，将所述当前CQI值和当前RI值上报至基站，以供所述基站根据所述当前CQI值和当前RI值提供所述终端的下行数据吞吐量，从而实现热缓和效果。由于有多个温度区间，且不同温度区间对应的不同的CQI最大值和RI最大值，从而使得终端在不同的温度区间上报不同的CQI值和RI值，达到快速且平滑降温/升温效果。
相应的，如图8所示，本申请实施例还提供了一种调控终端温度的装置，可以应用于终端，例如图5所示的终端100，调控终端温度的装置800包括：曲线获取模块801，配置为获取终端的温度变化曲线，所述温度变化曲线至少包括两个相邻的温度区间；
