Description

双卡UE数据传输方法及装置、存储介质、用户设备
本申请要求于2019年6月10日提交中国专利局、申请号为201910497715.5、发明名称为“双卡UE数据传输方法及装置、存储介质、用户设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信技术领域，尤其涉及一种双卡UE数据传输方法及装置、存储介质、用户设备。
背景技术
双卡用户设备(User Equipment,UE)是指能够使用两张用户身份识别卡Subscriber Identification Module,SIM)(以下简称SIM1和SIM2)的终端设备。双卡UE的两张SIM卡有可能需要同时占用通信基带及射频。比如：SIM1处于连接态时，SIM2执行寻呼接收、系统消息接收、信号测量和小区搜索等无线操作；更进一步，当接收到SIM2寻呼，或者需要SIM2对应无线资源控制(Radio Resource Control,RRC)请求按需(on demand0系统消息，或者用户主动发起SIM2接入时，执行接入网络操作；更进一步，当两个SIM卡都在连接态时，需要两个基站时分调度UE进行数据传输。两张SIM卡共用通信基带及射频时，需要解决两张SIM同时占用通信基带的问题。
现有技术中，为了解决两张SIM卡共用通信基带及射频的问题，一种方式是UE根据业务的优先级收发其中一路信号，而丢弃另一路信号。另一种方式是，在需要执行另一路信号收发时，UE提前发送上行数据缓存信息告知基站无上行数据要传输，等到另一路释放基带 及射频时，UE发送调度请求并在随后获得的上行传输机会中发送上行数据缓存信息告知基站需要传输的真实数据量。
但是，第一种方式会导致寻呼不到UE，数据传输性能下降，浪费网络无线资源，影响网络运营指标。第二种方式会影响数据传输的顺畅性，降低数据传效率。

具体实施方式
如背景技术中所述，第一种方式会导致寻呼不到UE，数据传输性能下降，浪费网络无线资源，影响网络运营指标。第二种方式会影 响数据传输的顺畅性，降低数据传效率。
本发明技术方案中，在第一SIM卡与第一服务基站相连接的状态下，通过向第一服务基站请求无数据传输时间间隙或射频资源来用于执行第二SIM卡的无线操作，可以在尽可能小的影响第一SIM卡的业务的情况下执行第二SIM的业务；也就是说，通过双卡UE以及基站之间的协调，可以避免浪费无线资源，并提升双卡UE的两张SIM卡的数据传输性能。
本发明实施例所称“无数据传输时间间隙”包括对当前服务基站的离线时长，其能够用于执行针对其他服务基站的无线操作，例如，当前服务基站为与第一SIM卡相连接的基站，则其他服务基站可以是第二SIM卡的服务基站。
本发明实施例所称“第一后续周期性离线模式”的参数包括周期、起始位置、每次离线持续时长，第一后续周期性离线模式中对第一服务基站的离线持续时长能够用于第二SIM卡的数据传输。
同理，本发明实施例所称“第二后续周期性离线模式”的参数包括周期、起始位置、每次离线持续时长，第二后续周期性离线模式中对第二服务基站的离线持续时长能够用于第一SIM卡的数据传输。
为使本发明的上述目的、特征和优点能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
图1是本发明实施例一种双卡UE数据传输方法的流程图。
本实施例中，所述双卡UE具有第一SIM卡和第二SIM卡。可以理解的是，第一SIM卡可以是双卡UE中其中一张SIM卡，而第二SIM卡则是另一张SIM卡。第一SIM卡和第二SIM卡并没有特殊的指代。
同理，本发明实施例中，第一SIM卡可以接入第一服务基站并与之建立连接，第二SIM卡可以接入第二服务基站并与之建立连接。第一服务基站和第二服务基站也没有特殊的指代。
本实施例的双卡UE数据传输方法可以由所述双卡UE来执行，也即由所述双卡UE执行图1所示的各个步骤。所述双卡UE数据传输方法具体可以包括以下方法：
步骤S101：在所述第一SIM卡处于连接态时，确定所述第二SIM卡的无线操作需求,所述第一SIM卡与第一服务基站相连接；
步骤S102：根据所述无线操作需求至少向所述第一服务基站请求无数据传输时间间隙或射频资源；
步骤S103：至少利用所述无数据传输时间间隙或射频资源执行所述第二SIM卡的无线操作。
需要指出的是，本实施例中各个步骤的序号并不代表对各个步骤的执行顺序的限定。
具体实施中，第一SIM卡处于连接态时，也即第一SIM卡与第一服务基站相连接时，第一SIM卡可以利用基带射频与第一服务基站进行数据传输。在这种情况下，第二SIM卡具有执行无线操作的需求。
在一个具体的实施例中，所述无线操作需求选自接入网络、寻呼接收、系统消息接收、信号测量和小区搜索。
需要说明的是，在实际的应用环境中，无线操作也可以是其他任意可实施的业务操作，本发明实施例对此不作限制。
在步骤S101的具体实施中，双卡UE可以确定第二SIM卡的无线操作需求，例如第二SIM卡需要执行寻呼的接收。
进而在步骤S102的具体实施中，双卡UE可以向第一服务基站请求无数据传输时间间隙(gap)或射频资源，以用于第二SIM卡的无线操作。具体地，无数据传输时间间隙可以是包括时间起点以及持续时长的一段时间。
在具体的实现中，双卡UE可以通过媒体接入控制(Media Access  Control,MAC)层的信道资源(Channel Element,CE)或者上行控制信息(Uplink Control Information,UCI)来请求无数据传输时间间隙或射频资源。
进一步而言，双卡UE除了可以向第一服务基站请求无数据传输时间间隙或射频资源之外，还可以向第一服务基站请求其他时间资源，以用于以上列举无线操作之外的其他业务，比如数据传输。例如，可以向第一服务基站请求第一后续周期性离线模式，以用于第二SIM卡接入第二服务基站后的数据传输业务。
第一服务基站可以响应于双卡UE的请求为双卡UE分配无数据传输时间间隙，进而在步骤S103的具体实施中，双卡UE可以利用所述无数据传输时间间隙或射频资源执行所述第二SIM卡的无线操作。
也就是说，如果第一SIM卡和第二SIM卡共用一套基带射频，则可以通过对基带射频的分时复用，也即在无数据传输时间间隙执行所述第二SIM卡的无线操作，在其他时间执行第一SIM卡的数据传输。如果第一SIM卡和第二SIM卡可以使用两套基带射频，则可以通过请求第一服务基站释放其中一套射频资源来执行第二SIM卡的无线操作。
本发明实施例中，在第一SIM卡与第一服务基站相连接的状态下，通过向第一服务基站请求无数据传输时间间隙或射频资源来用于执行第二SIM卡的无线操作，可以在尽可能小的影响第一SIM卡的业务的情况下执行第二SIM卡的业务；也就是说，通过双卡UE以及基站之间的协调，可以避免浪费无线资源，并提升双卡UE的两张SIM卡的数据传输性能。
在一个具体的应用场景中，双卡UE为单套基带射频UE，第一SIM卡和第二SIM卡(以下简称SIM1和SIM2)属于不同运营商，均工作在LTE模式，SIM1基站和SIM2基站时间(timing)同步，SIM1处于连接态，SIM2收到寻呼需要执行接入。双卡UE通过MAC CE 请求第一服务基站其后8ms处开始的32ms无数据传输时间间隙，同时请求第一后续周期性离线模式(也可以称为off service duration pattern1)，其中，off service duration pattern1的起始点为40ms处，周期为10ms，持续时长为5ms。
随后双卡UE在上述时长为32ms的无数据传输时间间隙执行对第二服务基站的接入，并在第32ms处通过MAC CE请求第二后续周期性离线模式(也可以称为off service duration pattern2)，其中，off service duration pattern2的起始点为45ms处，周期为10ms，持续时长为5ms。
在另一个具体的应用场景中，双卡UE为单套基带射频UE，SIM1和SIM2属于不同运营商，均工作在LTE模式，第一服务基站和第二服务基站时间不同步，SIM1处于连接态，SIM2需要执行寻呼接收。双卡UE通过UCI告知第一服务基站当前子帧后4ms开始需要一个长度为2ms的无数据传输时间间隙，以用于SIM2的寻呼接收。
在本发明一个非限制性的实施例中，图1所示步骤S102可以包括以下步骤：确定所述第二SIM卡的无线操作需求的时间开始位置；在所述时间开始位置之前并且与所述时间开始位置之间的时间间隔为第一偏移量的时刻，根据所述无线操作需求至少向所述第一服务基站请求无数据传输时间间隙。
本实施例中，双卡UE需要提前一定的时间来请求无数据传输时间间隙，以保证第二SIM卡的无线操作的顺利进行。
第一偏移量offset1可以由第一服务基站通过系统消息块(System Information Block,SIB)或者专用信令通知双卡UE，也可以由标准协议来约定，本发明实施例对此不作限制。
在本发明一个非限制性的实施例中，图1所示步骤S102可以包括以下步骤：如果所述无线操作需求所属的业务为周期性业务，则至少向所述第一服务基站发送请求，以请求周期性无数据传输时间间 隙，所述请求包括所述周期性无数据传输时间间隙的周期、起始位置以及持续时长。
具体实施中，在无线操作需求所属的业务为周期性业务的情况下，例如寻呼业务，则双卡UE可以向第一服务基站提供模式(pattern)，也即周期、起始位置以及持续时长，以请求周期性无数据传输时间间隙。
具体而言，该请求可以通过媒体接入控制(Media Access Control,MAC)层的信道资源(Channel Element,CE)或者RRC信令来发送。具体实施中，起始位置T的取值或取值范围可以由服务基站通过SIB或专用信令来配置，也可以由通信标准协议来约定。
其中，周期性无数据传输时间间隙的pattern可以不符合当前的非连续接收(Discontinuous Reception)配置，该请求也需要提前一定的时间来发出，例如相对于无线操作需求的时间开始位置提前第二偏移量。
此外，双卡UE也可以向第一服务基站请求关闭已获得的周期性无数据传输时间间隙。
在本发明一个非限制性的实施例中，图1所示步骤S102可以包括以下步骤：如果所述无线操作为接入网络，则向所述第一服务基站请求无数据传输时间间隙以及第一后续周期性离线模式(off service duration)，所述第一后续周期性离线模式中对第一服务基站的离线时间能够用于所述第二SIM卡的数据传输。
本实施例中，无线操作为接入网络的情况下，也即第二SIM卡需要接入第二服务基站，双卡UE除了请求无数据传输时间间隙，用于将第二SIM卡接入第二服务基站；双卡UE还可以请求第一后续周期性离线模式，以获得时间用于第二SIM卡与第二服务基站之间的数据传输。
进一步而言，请参照图2，上述步骤具体可以包括以下步骤：
步骤S201：确定所述第二SIM卡的无线操作需求的时间开始位置；
步骤S202：在所述时间开始位置之前并且与所述时间开始位置之间的时间间隔为第一偏移量的时刻，向所述第一服务基站请求所述无数据传输时间间隙；
步骤S203：在所述时间开始位置之前并且与所述时间开始位置之间的时间间隔为第二偏移量的时刻，向所述第一服务基站请求所述第一后续周期性离线模式。
具体实施中，双卡UE相对于时间开始位置T提前第一偏移量offset1通过MAC CE或UCI告知第一服务基站，需要一个无数据传输时间间隙，包括该无数据传输时间间隙的起点和时长。
双卡UE相对于时间开始位置T提前第二偏移量offset2向第一服务基站请求第一后续周期性离线模式，也即在未来的某个时刻T后需要周期性的执行第二SIM卡的数据传输业务。
进一步而言，请参照图3，图1所示步骤S103可以包括以下步骤：
步骤S301：利用所述无数据传输时间间隙执行所述第二SIM卡与第二服务基站的接入过程；
步骤S302：在所述第二SIM卡接入所述第二服务基站后，向所述第二服务基站请求第二后续周期性离线模式，所述第二后续周期性离线模式的参数至少包括周期、起始位置、每次离线持续时长，所述对第二服务基站的第二后续周期性离线模式中对第二服务基站的离线时间能够用于所述第一SIM卡的数据传输。
本实施例中，双卡UE的第一SIM卡与第一服务基站处于连接状态，双卡UE在无数据传输时间间隙可以执行第二SIM卡与第二服务基站的接入过程，以完成第二SIM卡接入第二服务基站。
第二SIM卡接入第二服务基站之后，双卡UE可以向所述第二服务基站请求第二后续周期性离线模式，以利用所述第二后续周期性离线模式进行所述第一SIM卡与所述第一服务基站的数据传输。
更进一步地，如果第二SIM卡在接入第二服务基站后发现原本请求的第一后续周期性离线模式不能满足业务需求，则可以请求更新第一后续周期性离线模式，请参照图4，具体可以包括以下步骤：
步骤S401：在所述第二SIM卡接入第二服务基站后，如果所述第一后续周期性离线模式中对第一服务基站的离线时间不能满足所述第二SIM卡与所述第二服务基站的业务需求，则向所述第二服务基站请求新的无数据传输时间间隙；
步骤S402：利用所述新的无数据传输时间间隙向所述第一服务基站请求新的第一后续周期性离线模式。
本实施例中，由于第二SIM卡已接入第二服务基站，因此如果需要向第一服务基站请求新的第一后续周期性离线模式，则需要先向第二服务基站请求一个新的无数据传输时间间隙，该新的无数据传输时间间隙可以用来供双卡UE向第一服务基站请求新的第一后续周期性离线模式。
在一个具体的应用场景中，双卡UE为单套基带射频UE，第一SIM卡和第二SIM卡(以下简称SIM1和SIM2)属于不同运营商或相同运营商，SIM1工作在宽带码分多址(Wideband Code Division Multiple Access,W-CDMA)连接模式服务于语音业务，所以SIM1对基带和射频的占用模式是以20ms为周期的。SIM2工作在长期演进(Long Term Evolution，LTE)模式需要执行接入，在接入过程中直接将SIM1对基带和射频的占用pattern用于请求off service duration。
在另一个具体的应用场景中，请参照图5，SIM1工作在LTE连接模式服务于数据业务，SIM2工作在WCDMA模式需要执行接入，UE通过MAC CE在时刻T1请求第一服务基站其后8ms处开始的长 度为92ms无数据传输时间间隙1，同时请求第一后续周期性离线模式(起始点：100ms处，周期为10ms，持续时长5ms)。随后UE在上述长度为92ms的无数据传输时间间隙内对执行对第二服务基站的接入，得知SIM2接入是为语音业务且从SIM1基站获得的第一后续周期性离线模式的离线时间无法满足SIM2的语音数据传输，此种情况下，双卡UE需要向第二服务基站请求一个新的无数据传输间隙以重新向第一服务基站请求新的第一后续周期性离线模式。由此，双卡UE在时刻T2向第二服务基站请求一个新的无数据传输间隙2。双卡UE在无数据传输间隙2内的时刻3通过MAC CE向第一服务基站请求新的第一后续周期性离线模式。
在一个具体实施例中，步骤S102可以包括以下步骤：如果所述无线操作为接入网络，所述第一SIM卡处于载波聚合状态且使用至少两路射频资源，则向所述第一服务基站请求释放所述至少两路射频资源中至少一路射频资源。
本实施例中，由于载波聚合(Component Carrier,CC)可以将多个载波聚合在一起，因此如果第一SIM卡处于载波聚合状态且使用至少两路射频资源，双卡UE可以请求第一服务基站释放所述至少两路射频资源中至少一路射频资源，以用于第二SIM卡的接入操作。
在另一个具体实施例中，步骤S102可以包括以下步骤：如果所述无线操作为接入网络，且所述第一SIM卡处于双连接状态，则向所述第一服务基站请求释放其中一路连接对应的射频资源。
本实施例中，第一SIM卡处于双连接状态表示第一SIM卡同时接入两个基站，占用两路射频资源，因此双卡UE可以请求第一服务基站释放其中一路连接对应的射频资源，以用于第二SIM卡的接入操作。
在一个具体应用场景中，双卡UE为两套基带射频UE，SIM1和SIM2属于不同运营商或相同运营商，均工作在LTE模式，SIM1处于双连接态，占用两套基带射频，SIM2需要执行接入，通过RRC  Assistant Information请求第一服务基站释放第二连接，随后收到第一服务基站发过来的RRC Reconfiguration信令释放第二连接，双卡UE使用被释放的第二连接所对应的基带和射频用于SIM2的接入和连接。
请参照图6，本发明实施例还公开了一种双卡UE数据传输装置60，所述双卡UE具有第一SIM卡和第二SIM卡，所述装置60可以包括无线操作需求确定模块601、请求模块602和操作模块603。
其中，无线操作需求确定模块601适于在所述第一SIM卡处于连接态时，确定所述第二SIM卡的无线操作需求,所述第一SIM卡与第一服务基站相连接；请求模块602适于根据所述无线操作需求至少向所述第一服务基站请求无数据传输时间间隙或射频资源；操作模块603适于至少利用所述无数据传输时间间隙或射频资源执行所述第二SIM卡的无线操作。
本发明实施例中，在第一SIM卡与第一服务基站相连接的状态下，通过向第一服务基站请求无数据传输时间间隙或射频资源来用于执行第二SIM卡的无线操作，可以在尽可能小的影响第一SIM卡的业务的情况下执行第二SIM卡的业务；也就是说，通过双卡UE以及基站之间的协调，可以避免浪费无线资源，并提升双卡UE的两张SIM卡的数据传输性能。
关于所述双卡UE数据传输装置60的工作原理、工作方式的更多内容，可以参照图1至图5中的相关描述，这里不再赘述。
