请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个终端11以及若干个基站12。
其中，终端11可以是指向用户提供语音和/或数据连通性的设备。终端11可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，终端11可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户终端(user equipment，UE)。或者，终端11也可以是无人飞行器的设备。或者，终端11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线通信设备。或者，终端11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站12可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。或者，MTC系统。
其中，基站12可以是4G系统中采用的演进型基站(eNB)。或者，基站12也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站12的具体实现方式不加以限定。
基站12和终端11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，终端11之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
在一些实施例中，上述无线通信系统还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信系统中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实施例不做限定。
本公开实施例涉及的执行主体包括但不限于：支持多用户识别模块的终端，基站等。
本公开实施例的应用场景为，对于多用户识别模块(SIM)终端某多卡终端的其中一个用户识别模块处于无线资源控制(RRC，Radio Resource Control)连接态，并且处于上行失步状态时，如果基站有下行数据需要发送给该用户识别模块，则需要针对用户识别模块启动随机接入流程来确定定时提前量，而该随机接入流程会占用网络资源，并消耗终端电量。
如图2所示，本示例性实施例提供一种定时提前量指示方法，定时提前量指示方法可以用于终端等无线通信设备中，包括：
步骤201：在终端包含至少两个用户识别模块时，将所述至少两个用户识别模块中第一用户识别模块的定时提前量，提供给所述至少两个用户识别模块中至少一个第二用户识别模块使用。
这里，所述终端可以是多用户识别模块终端，所述终端的行为模式可以是双卡双待单通、双卡双待双通等。
所述用户识别模块可以是以单独个体形式存在的用户识别模块(SIM，Subscriber Identification Module)卡或以集成形式存在于终端内部在的集成 用户识别模块(e-SIM，embedded Subscriber Identification Module)等。
基站可以通过终端的上报信息等确定所述第一用户识别模块和第二用户识别模块属于同一终端；终端可以将上报信息直接发送给基站，也可以将上报信息发送给核心网，由核心网将上报信息发送给终端连接的基站。
这里，将所述至少两个用户识别模块中第一用户识别模块的定时提前量，提供给所述至少两个用户识别模块中至少一个第二用户识别模块使用；可以是将第一用户识别模块的定时提前量，写入到用于存储第二用户识别模块的定时提前量的寄存器中。如此，在第二用户识别模块向基站发送数据时，采用第一用户识别模块的定时提前量作为自身定时提前量，用于补偿由于终端和基站之间的距离产生的传输时延。其中，第一用户识别模块包括但不限于：处于上行同步的用户识别模块。
第二用户识别模块不需要发起随机接入流程就可以获取定时提前量，从而，减少由于发起随机接入流程而占用的网络资源以及消耗的终端电量，延长终端待机时间。
在一个实施例中，在所述将所述第一用户识别模块的定时提前量，提供给所述第二用户识别模块使用之前，所述方法还包括：接收基站发送的所述第一用户识别模块的定时提前量。
第一用户识别模块为处于上行同步的用户识别模块，在基站和终端分别都保存有第一用户识别模块的定时提前量。
本实施例提供的从基站接收第一用户识别模块的定时提前量的方式，可以适用于终端未存储有第一用户识别模块的定时提前量，或者，终端存储的第一用户识别模块的定时提前量失效的情况下。
这里，可以通过基站向终端发送保存在基站的第一用户识别模块的定时提前量。
在一个实施例中，所述接收基站发送的所述第一用户识别模块的定时 提前量，包括：通过所述第二用户识别模块，接收所述基站发送的所述第一用户识别模块的定时提前量。
基站可以直接将保存在基站的第一用户识别模块的定时提前量发送给第二用户识别模块，由终端通过第二用户识别模块接收。例如，通过定时提前量(TA，Timing Advance)命令(Command)媒体接入控制元(MAC CE，MAC Control Element)等指令将第一用户识别模块的定时提前量发送给第二用户识别模块。终端可以通过解析该指令得到第一用户识别模块的定时提前量。
在一个实施例中，所述接收基站发送的所述第一用户识别模块的定时提前量，包括：通过所述第一用户识别模块，接收所述基站发送的所述第一用户识别模块的定时提前量。
基站可以向第一用户识别模块发送提供给第二用户识别模块的第一用户识别模块的定时提前量，并由终端通过所述第一用户识别模块进行接收。
在一个实施例中，所述将所述至少两个用户识别模块中第一用户识别模块的定时提前量，提供给所述至少两个用户识别模块中至少一个第二用户识别模块使用，包括：将通过所述第一用户识别模块接收的所述第一用户识别模块的定时提前量，转发给所述第二用户识别模块使用。
终端通过所述第一用户识别模块接收所述第一用户识别模块的定时提前量后，可以通过终端内部总线等，将接收到的第一用户识别模块的定时提前量，转发给所述第二用户识别模块使用。
在一个实施例中，所述方法还包括：接收基站发送的指示信息；所述将所述第一用户识别模块的定时提前量，提供所述第二用户识别模块使用，包括：接收根据所述指示信息，将所述第一用户识别模块的定时提前量提供所述第二用户识别模块使用。
这里，所述指示信息可以预先在基站和终端两侧商定。接收到指示信 息后，终端可以将保存在终端的第一用户识别模块的定时提前量，提供所述第二用户识别模块使用。其中，第一用户识别模块的定时提前量可以是保存在第一用户识别模块对应寄存器中的定时提前量。
在一个实施例中，所述第二用户识别模块为处于RRC连接态，并且处于上行失步状态的用户识别模块。
当第二用户识别模块处于RRC连接态，并且处于上行失步状态时，如果基站发起数据通信，终端首先进行随机接入进而获取第二用户识别模块的定时提前量。因此，在该状态不发起随机接入流程，而将第一用户识别模块的定时提前量提供给第二用户识别模块使用，可以适时满足终端通信需求，并且减少由于发起随机接入流程而占用的网络资源以及消耗的终端电量，延长终端待机时间。
在一个实施例中，所述第一用户识别模块和所述至少一个第二用户识别模块所连接的网络，属于相同运营商。
如果第一用户识别模块和第二用户识别模块所连接的网络属于相同运营商，那么第一用户识别模块和第二用户识别模块可能较大概率的连接到同一个基站。如此，第一用户识别模块和第二用户识别模块到基站的距离相同，即可以采用相同的定时提前量。如此，第二用户识别模块使用第一用户识别模块的定时提前量，可以更精确补偿传输时延。
同时，在实际应用中，对于同一运营商的用户识别模块更具有可操作性。同一基站可以实现与第一用户识别模块和第二用户识别模块的通信连接。
如图3所示，本示例性实施例提供一种定时提前量指示方法，定时提前量指示方法可以用于基站中，所述方法包括：
步骤301：在终端包含至少两个用户识别模块时，
下发所述至少两个用户识别模块中第一用户识别模块的定时提前量， 其中，下发的所述第一用户识别模块的定时提前量，用于供所述至少两个用户识别模块中至少一个第二用户识别模块使用；
或者，
向所述终端发送指示信息，其中，所述指示信息，用于指示所述终端将所述第一用户识别模块的定时提前量提供给所述至少一个第二用户识别模块使用。
这里，所述终端可以是多用户识别模块终端，所述终端的行为模式可以是双卡双待单通、双卡双待双通等。
所述用户识别模块可以是以单独个体形式存在的用户识别模块(SIM，Subscriber Identification Module)卡或以集成形式存在于终端内部在的集成用户识别模块(e-SIM，embedded Subscriber Identification Module)等。
基站可以通过终端的上报信息等确定所述第一用户识别模块和第二用户识别模块属于同一终端；终端可以将上报信息直接发送给基站，也可以将上报信息发送给核心网，由核心网将上报信息发送给终端连接的基站。
第一用户识别模块为处于上行同步的用户识别模块，在基站和终端分别都保存有第一用户识别模块的定时提前量。
本实施例提供的从基站接收第一用户识别模块的定时提前量的方式，可以适用于终端未存储有第一用户识别模块的定时提前量，或者，终端存储的第一用户识别模块的定时提前量失效的情况下。
可以通过基站向终端发送保存在基站的第一用户识别模块的定时提前量，由终端接收并提供给第二用户识别模块使用；或者，发送指示信息，由终端将保存在终端的第一用户识别模块的定时提前量提供给第二用户识别模块使用。
这里，所述指示信息可以预先在基站和终端两侧商定。接收到指示信息后，终端可以将保存在终端的第一用户识别模块的定时提前量，提供所 述第二用户识别模块使用。其中，第一用户识别模块的定时提前量可以是保存在第一用户识别模块对应寄存器中的定时提前量。
这里，将所述至少两个用户识别模块中第一用户识别模块的定时提前量，提供给所述至少两个用户识别模块中至少一个第二用户识别模块使用；可以是将第一用户识别模块的定时提前量，写入到用于存储第二用户识别模块的定时提前量的寄存器中。如此，在第二用户识别模块向基站发送数据时，采用第一用户识别模块的定时提前量作为自身定时提前量，用于补偿由于终端和基站之间的距离产生的传输时延。其中，第一用户识别模块包括但不限于：处于上行同步的用户识别模块。
第二用户识别模块不需要发起随机接入流程就可以获取定时提前量，从而，减少由于发起随机接入流程而占用的网络资源以及消耗的终端电量，延长终端待机时间。
在一个实施例中，所述下发所述第一用户识别模块的定时提前量，包括：向所述第一用户识别模块发送所述第一用户识别模块的定时提前量；或者，向所述至少一个第二用户识别模块发送所述第一用户识别模块的定时提前量。
基站可以直接将保存在基站的第一用户识别模块的定时提前量发送给第二用户识别模块，由终端通过第二用户识别模块接收。例如，通过TA Command MAC CE等指令将第一用户识别模块的定时提前量发送给第二用户识别模块。终端可以通过解析该指令得到第一用户识别模块的定时提前量。
基站也可以向第一用户识别模块发送提供给第二用户识别模块的第一用户识别模块的定时提前量，并由终端通过所述第一用户识别模块进行接收。
终端通过所述第一用户识别模块接收所述第一用户识别模块的定时提 前量后，可以通过终端内部总线等，将接收到的第一用户识别模块的定时提前量，转发给所述第二用户识别模块使用。
在一个实施例中，在所述下发所述第一用户识别模块的定时提前量、或、发所述送指示信息之前，所述方法还包括：
确定所述第一用户识别模块的定时提前量是否有效；
所述下发所述第一用户识别模块的定时提前量，包括：
当所述第一用户识别模块的定时提前量有效时，下发所述第一用户识别模块的定时提前量；
所述向所述终端发送指示信息，包括：
当所述第一用户识别模块的定时提前量有效时，向所述终端发送所述指示信息。
这里，可以通过第一用户识别模块的定时提前量对应寄存器中是否有相应的定时提前量、或、以及第一用户识别模块的定时提前量的更新频率、或、第一用户识别模块的定时提前量与有效阈值范围比较等来确定所述第一用户识别模块的定时提前量是否有效。
如此，可以提升定时提前量的有效性，提高第二用户识别模块采用第一用户识别模块的定时提前量进行数据传输的成功率。
以下结合上述任意实施例提供一个具体示例：
本示例针对双卡用户设备(UE)的两个用户识别模块(SIM)卡属于同一个运营商的场景；
一个多卡终端的SIM卡#1处于RRC连接态，并且处于上行失步状态时；如果此时基站有下行数据需要给发送给SIM卡#1，则基站检查与该SIM卡所处终端的其他SIM卡是否具有有效的TA值，如果有，则将该TA值发送给该SIM卡#1。
发送方式可以为基站直接发送给该SIM卡#1，例如通过TA命令 (Command)媒体接入控制元(MAC CE，MAC Control Element)；
发送方式也可以为基站将有效TA值发送给具有有效TA值的SIM卡，该SIM卡再将收到的有效的TA值转发给SIM卡#1；
发送方式还可以为基站直接指示具有有效TA值的SIM卡直接将自身TA值告知给。
然后终端收到有效TA值后，利用该TA值使SIM卡#1与基站进行数据传输。
如果该多卡终端的其他SIM卡均没有有效的TA值，则基站触发该SIM卡进行随机接入获取有效的TA值。
