技术领域
本申请实施例涉及通信技术领域，具体涉及一种通信控制方法、装置、通信设备及存储介质。
背景技术
在大型建筑物、地下商场、地下停车场等室内环境下，移动通信信号较弱，极易形成移动通信的盲区和阴影区，导致手机等利用移动通信信号的终端无法正常使用。室内分布系统可用于改善室内环境的移动通信信号，利用室内分布系统可将基站信号均匀分布在室内每个角落，从而保证室内环境下拥有理想的信号覆盖。
室内分布系统的信号源主要有以下几种：以宏蜂窝作为信号源接入室内分布系统；以微蜂窝作为信号源接入室内分布系统；以直放站作为信号源接入室内分布系统。其中，直放站是利用施主天线空间耦合或利用耦合器件直接耦合存在富余容量的基站信号，再对接收到的信号进行放大，从而提供给室内分布系统。可见，室内分布系统可直接连接基站信号，也可是直放站连接基站信号后，再由直放站为室内分布系统提供基站信号。
随着5G(第五代移动通信技术)建设的加速，在由室内分布系统连接基站信号，或者由直放站连接基站信号时，如何在4G(第四 代移动通信技术)基础上实现5G通信控制，成为了本领域技术人员亟需解决的问题。

附图说明
为了更清楚地说明本申请实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而 易见地，下面描述中的附图仅仅是本申请的实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据提供的附图获得其他的附图。

具体实施方式
在实现室内信号覆盖时，本申请实施例可直接由室内分布系统连接室外的基站信号，由室内分布系统对基站信号进行处理后，将基站信号覆盖在室内；也可由直放站连接室外的基站信号，由直放站对基站信号进行处理后传输给室内的室内分布系统，由室内分布系统实现基站信号在室内的覆盖；
在一种示例中，室内分布系统或者直放站的原理示例可如图1所示，图1中PA(Power Amplifier)为功率放大器，LNA为(Low Noise Amplifier)为低噪声放大器，PMU(Power Management Unit)为电源管理单元，从图1可以看出：室外射频部分接收室外的基站信号，并 送入基带芯片，基带芯片同步并驻留在合适的小区上，然后打开室内射频部分，将基站信号放大后送入室内；图1示例的室外的基站信号通过放大传输到室内的链路可称为下行放大链路，室内信号放大传输到室外的链路可称为上行放大链路，其中，在上行放大链路传输放大信号到室外时，信号也进入基带芯片，基带芯片根据接收到的信号做频率跟踪和功率控制等处理。
在更进一步的说明中，如图2所示，室内分布系统主要包括主节点01和多个从节点02，其中，主节点连接基站信号(主节点可以直接连接室外的基站信号，也可以连接直放站提供的基站信号)，将基站信号发送到从节点，从节点将接收到的基站信号处理后，发送到空口，完成基站信号在室内环境的覆盖。可见，室内分布系统可由主节点连接基站信号，并进行处理后传输给从节点。
在实现室内信号覆盖的场景下，室内分布系统可以直接连接室外的基站信号，也可连接直放站提供的基站信号，而随着5G建设的加速，由于目前直放站或室内分布系统大都建立在4G基础上，并不支持5G高频段，且无源器件损耗大，质量参差不齐，末端覆盖不能满足要求；同时随着5G高速率的要求，目前的室内分布系统并不支持5G的MIMO(Multiple-In Multiple-Out，多进多出)，若完全新建两条无源室内分布系统来支持MIMO(多进多出)，则成本高且施工难，并难以实现完整的网管实时监控，管理和维护排障也存在困难。可见，目前4G基础上的直放站或室内分布系统难以实现5G通信控制，这将导致诸多进一步问题的产生，因此在直放站或室内分布系统的4G基础上实现5G通信控制，成为了本领域技术人员亟需解决的技术问题。
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做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。
在本申请实施例中，通信设备可以设置5G芯片和4G芯片，由5G芯片实现小区搜索和基站同步，从而4G芯片基于5G芯片提供的信息进行通信控制，以实现在4G基础上实现5G通信控制，即在本申请实施例中，小区搜索与基站同步可由5G芯片完成，通信控制可由4G芯片完成；需要说明的是，所述通信设备可以是直放站或者室内分布系统，在通信设备为室内分布系统时，通信设备可以具体为室内分布系统中的主节点；
在可选实现中，图3示出了本申请实施例提供的通信控制方法的流程，该流程可由通信设备执行，参照图3，该流程可以包括：
步骤S100、利用5G芯片搜索小区及进行基站同步。
步骤S100可由通信设备的5G芯片实现；可选的，通信设备在开机上电后，通信设备中的5G芯片可以搜索小区及进行基站同步。
在进行基站同步的可选实现中，本申请实施例可利用5G芯片接收下行基站信号，根据所述下行基站信号进行基站同步；当然，本申请实施例也可采用其他方式实现基站同步，本申请实施例对此并不设限。
在利用5G芯片搜索小区及进行基站同步的过程中，通信设备的上行放大链路和下行放大链路保持关闭状态，即通信设备不对室内信号进行放大并传输到室外，也不对室外基站信号进行放大并传输到室内。
步骤S110、利用5G芯片获取上行时隙和下行时隙的时隙配比信息。
步骤S110可由通信设备的5G芯片实现；通信设备基于5G芯片 与基站进行同步后，可利用5G芯片读取基站广播信号，从基站广播信号中获取上行时隙和下行时隙的时隙配比信息，所述时隙配比信息可以表示上行与下行的时隙配比关系。
在更为具体的可选实现中，在进行基站同步后，本申请实施例可利用5G芯片读取第一系统信息块(SIB1)，从第一系统信息块中获取所述时隙配比信息。

步骤S120可由通信设备的4G芯片实现；4G芯片可获取5G芯片确定的所述时隙配比信息，从而4G芯片可基于所述时隙配比信息，控制上行放大链路和下行放大链路的开关状态。
可见，通信设备的4G芯片可在通信设备的5G芯片与基站同步，并基于5G芯片获取的上行时隙和下行时隙的时隙配比信息，控制上行放大链路和下行放大链路的开关状态，从而4G芯片可在5G芯片建立与基站的5G连接和同步后，在5G通信的情况下，实现通信设备的上行放大链路和下行放大链路的开关控制，使得室外的基站信号能够通过下行放大链路放大传输到室内，而室内信号也可通过上行放大链路传输到室外，实现在4G基础上的5G通信控制。
在可选实现中，结合图4所示，根据所述时隙配比信息，控制上行放大链路和下行放大链路的开关状态可以注意以下至少一项原则：
控制下行放大链路打开的时间应包含所有的下行时隙传输时间，同样，控制上行放大链路打开的时间应包含所有的上行时隙传输时间；
控制下行放大链路的结束时间和上行放大链路的起始时间之间存在预设的保护间隔时间(保护间隔时间如图4所示t)，以防止上行放大链路和下行放大链路在很短的时间处于同时打开状态，形成上下行闭环的自激。
需要说明的是，图4中GP(Guard Space，保护间隔)可以根据上行时隙、下行时隙的长度决定，GP大小决定了通信设备支持的小区半径的大小。
本申请实施例提供的通信控制方法中，通信设备(如直放站或者室内分布系统)可利用5G芯片搜索小区及进行基站同步，并获取上行时隙和下行时隙的时隙配比信息；从而，在通信设备基于5G芯片建立与基站的5G连接和同步后，通信设备可利用4G芯片根据所述时隙配比信息，控制上行放大链路和下行放大链路的开关状态。可见，在本申请实施例中，通信设备的4G芯片可在通信设备的5G芯片建立与基站的5G连接和同步后，在5G通信的情况下，实现通信设备的上行放大链路和下行放大链路的开关控制，使得室外的基站信号能够通过下行放大链路放大传输到室内，而室内信号也可通过上行放大链路传输到室外，实现在4G基础上的5G通信控制。
在可选实现中，通信设备的5G芯片还可获取RSSI(Received Signal Strength Indication，接受信号强度)值，并提供给通信设备的4G芯片；从而4G芯片可获取5G芯片提供的RSSI值，根据RSSI值控制通信设备的前级LNA(低噪声放大器)是处于正常工作模式，还是处于旁路(Bypass)模式；可选的，图5示出了本申请实施例提供的通信控制方法的另一流程，参照图5，该流程可以包括：
步骤S200、利用5G芯片获取RSSI值。
步骤S210、利用4G芯片判断所述RSSI值是否小于设定值，若是，执行步骤S220，若否，执行步骤S230。
步骤S220、利用4G芯片控制前级LNA处于正常工作模式。
步骤S230、利用4G芯片控制前级LNA处于旁路模式。
在具体的可选实现中，若所述RSSI值小于设定值，则利用4G芯片可控制前级LNA处于正常工作模式，若所述RSSI值不小于设定 值，则利用4G芯片可控制前级LNA处于旁路模式；设定值的具体数值可根据实际情况确定，例如-45dbm等，本申请实施例并不限制。
需要说明的是，结合图1所示，通信设备的前级LNA用于在下行放大链路中对由室外传输向室内的信号进行放大，在上行放大链路中对由室内传输向室外的信号进行放大；本申请实施例由4G芯片基于5G芯片提供的RSSI值，决定前级LNA是处于正常工作模式还是旁路模式，能够对上行放大链路和下行放大链路进行进一步的控制，实现进一步在4G基础上的5G通信控制。
在可选实现中，如果通信设备采用开环功控功能，则5G芯片可从基站广播信号中获取基站期望上行功率，并提供给4G芯片；从而4G芯片可基于所述基站期望上行功率，确定上行发送最大功率，进而4G芯片可基于确定的上行发送最大功率，在上行放大链路传输信号，以实现基于4G的5G通信信号上行传输；可选的，图6示出了本申请实施例提供的通信控制方法的再一流程，参照图6，该流程可以包括：
步骤S300、利用5G芯片从基站广播信号中获取基站期望上行功率。
步骤S310、利用4G芯片根据所述基站期望上行功率，确定上行发送最大功率。
可选的，5G芯片在获取基站期望上行功率后，可将所述基站期望上行功率传输给4G芯片，从而4G芯片可基于所述基站期望上行功率，计算上行发送最大功率。
在更为具体的可选实现中，步骤S310的可选实现可如图7所示，包括：
步骤S400、利用4G芯片根据所述基站期望上行功率确定上行开环功控功率。
可选的，基站期望上行功率可以表示基站期望信号到达基站处的功率强度，基于基站期望上行功率，本申请实施例可确定上行开环功控功率，上行开环功控功率可以认为是通信设备采用开环功控功能的情况下，上行放大链路的开环功控功率；
可选的，本申请实施例可采用如下公式1计算上行开环功控功率：
Power_ul_open＝Power_p0n_pusch+α*PL+
10log10(RBnum)+offset，公式1；
其中，Power_ul_open为上行开环功控功率；Power_p0n_pusch为基站期望上行功率，表示基站期望信号到达基站处的功率强度；α为路损纠正系数，可根据实际情况设置α的值，如取α为1；PL可以表示为Power_rs–RSRP，其中，Power_rs为参考信号发送功率，可从基站广播信号中获取，RSRP为参考信号接收功率，可通过测量获得；10log10(RBnum)表示SRS(探测参考信号)配置一定数量的RB(资源块)之后的功率偏置；offset为设定的偏移值。
步骤S410、利用4G芯片从所述上行开环功控功率和设置的上行最大发射功率中，选取最小值作为计算的上行发送最大功率。
在基于基站期望上行功率确定上行开环功控功率后，本申请实施例可调取设置的上行最大发射功率，所述设置的上行最大发射功率的数值可根据实际情况设置，从而本申请实施例可从所述上行开环功控功率和设置的上行最大发射功率中，选取最小值作为上行发送最大功率，即上行开环功控功率和设置的上行最大发射功率中数值较小的作为上行发送最大功率；
可选的，本申请实施例可采用如下公式2计算上行发送最大功率：
Power_ul_max＝min(Power_ul_max_set,Power_ul_open)，公式2；
其中，Power_ul_max为计算的上行发送最大功率；Power_ul_max_set为设置的上行最大发射功率，Power_ul_max_set可 以根据情况预先设置，例如设置17dbm等，本申请实施例并不限制；Power_ul_open为上行开环功控功率。
回到图6，本申请实施例可执行步骤S320：利用4G芯片基于所述上行发送最大功率，在上行放大链路传输信号。
在计算出上行发送最大功率，明确了基站期望信号到达基站处的功率强度后，本申请实施例可基于所述上行发送最大功率，在上行放大链路传输信号，从而使得由室内传输向室外的信号到达基站处时，能够符合基站期望信号到达基站处的功率强度，实现在上行放大链路，精准的基于4G的5G通信控制。
在进一步的可选实现中，通信设备的5G芯片可从基站广播信号中获取基站下行功率，从而4G芯片可基于所述基站下行功率，计算下行最大功率；进而，基于计算的下行最大功率，4G芯片可在下行放大链路，以所述下行最大功率传输信号，实现在下行放大链路，精准的基于4G的5G通信控制。
