Description

一种实现双卡双待双通的通信方法及终端
本申请要求于2017年03月25日提交中国专利局、申请号为201710184955.0、发明名称为“一种实现双卡双待双通的方法”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
本申请实施例涉及通信技术领域，尤其涉及一种实现双卡双待双通的通信方法及终端。
背景技术
随着通信技术的发展，很多移动终端(如手机)都具备双卡双待功能。其中，双卡双待是指一个手机中同时安装两张用户识别模块(Subscriber Identity Module，SIM)卡，这两张SIM卡可以同时在网待机。
目前，双卡双待双通(Dual SIM Dual Active，DSDA)技术已经被应用于支持双收单发的双卡双待单通(Dual Receive-Dual SIM Dual Standby，DR-DSDS)的手机。支持DR-DSDS的手机中仅配置有一路射频发射(Transmit，Tx)通路和两路射频接收(Receive，Rx)通路，当SIM卡1进行语音数据传输时，SIM卡2可以接收寻呼(paging)请求；在SIM卡2接收到paging请求后，支持DR-DSDS的手机可以响应该paging请求向网络设备发送无线资源控制(Radio Resource Control，RRC)信令，以便于与网络设备建立RRC连接，执行该paging请求对应的业务。
但是，在“当SIM卡1进行语音数据传输时，SIM卡2可以接收paging请求”的场景下，如果支持DR-DSDS的手机响应该paging请求，占用射频Tx通路向网络设备发送RRC信令，则会因为RRC信令占用射频Tx通路，导致支持DR-DSDS的手机待发送的SIM卡1的语音包延迟发送，影响SIM卡1的语音通信质量。
发明内容
本申请提供一种实现双卡双待双通的通信方法及终端，能够有效的保证第一SIM卡的语音通话质量，并且能够实现支持DR-DSDS的终端的双卡双待双通，提高用户体验。
为达到上述目的，本申请采用如下技术方案：
第一方面，提供一种实现双卡双待双通的通信方法，该方法应用于支持DR-DSDS的终端，该终端包括第一SIM卡接口和第二SIM卡接口，该第一SIM卡接口用于与第一SIM卡通信，该第二SIM卡接口用于与第二SIM卡通信，该方法包括：终端处于第一通信连接(即终端在执行与第一SIM卡相关的第一业务)时，接收建立与第二SIM卡相关的第二通信连接的寻呼请求(即对第二SIM卡的paging请求)；在终端收到的第二通信连接的寻呼请求携带 用于表示第二业务的第一标识的情况下，终端立即响应建立第二通信连接的寻呼请求。
本申请中，在第一业务和第二业务均为语音通话的场景中，在终端处于与第一SIM卡相关的通话状态时，如果终端收到对第二SIM卡的paging请求，且该paging请求携带有用于表示语音通话的第一标识，该终端响应该paging请求，进行第二SIM卡的来电提醒，实现终端的双卡双待双通，可以提高用户体验。进一步地，本申请中的终端只有在paging请求携带第一标识的情况下，才响应该paging请求，降低了用于数据连接的寻呼请求对第一SIM卡的语音通话的干扰，降低了对第一SIM卡的语音通话质量的影响。
综上而言，通过本方案，终端可以有效的降低对第一SIM卡的语音通话质量，还可以实现终端的双卡双待双通，提高用户体验。

具体实施方式
本申请实施例提供一种实现双卡双待双通的通信方法，该方法可以应用于支持DR-DSDS的终端中，该终端可以安装两张SIM卡(第一SIM卡和第二SIM卡)，并且该终端中配置有一路射频发射(Tx)通路和两路射频接收(Rx)通路。上述终端中的第一SIM卡和第二SIM卡可以分别单独占用使用这两路射频Rx通路中的一路射频Rx通路，分时使用该终端中的一路射频Tx通路。
请参考图1，其示出了本申请实施例提供的一种支持DR-DSDS的终端的结构示意图。如图1所示，终端100可以包括：第一SIM卡接口110、第二SIM卡接口120、与第一SIM卡接口110和第二SIM卡接口120分别耦合的管理器140、与管理器140耦合的处理器130，处理器130连接收发器150。其中，上述处理器130可以为基带处理器(Base Band Processor，BBP)。如图1所示，收发器150中包括射频Rx1通路、射频Rx2通路和射频Tx通路。
其中，上述第一SIM卡接口110用于安装SIM卡1，与SIM卡1通信，上述第二SIM卡接口120用于安装SIM卡2，与SIM卡2通信。管理器140可以向处理器130发送与SIM卡1的业务相关的上行数据包，以及发送与SIM卡2的业务相关的上行数据包。处理器130可以按照SIM卡1和SIM卡2的各个上行数据包在射频Tx通路上的发射优先级，在射频Tx通路向网络设备发送上行数据包。
应注意，本申请实施例中的射频Tx通路也可以称为Tx射频资源或发射器(Transmitter)，射频Rx通路也可以称为Rx射频资源或接收器(Receiver)。
其中，本申请实施例中还可以将上述射频Tx通路和射频Rx1通路称为RF主通道，将上述射频Rx2通路称为RF副通道。即该RF主通道中的上下行RF器件(如射频Tx通路和射频Rx1通路)复用，RF副通道只有下行RF器件(如射频Rx2通路)。
具体的，本申请实施例提供的实现双卡双待双通的通信方法可以用于当上述支持DR-DSDS的终端的一个SIM卡(如第一SIM卡，或者SIM卡1)占用上述Tx射频资源完成第一业务(例如，第一业务为语音通话)时，即终端处于第一通信连接时，如果另一个SIM卡(如第二SIM卡，或者SIM卡2) 有第二业务(例如第二业务为语音通话或数据业务)的第一寻呼(paging)请求接入(即终端接收到携带有第一标识的用于建立第二通信连接的第一paging请求)，该终端响应该第一paging请求，创建第二通信连接，实现第二SIM卡的第二业务。其中，第一通信连接是指与第一SIM卡相关的第一业务，第二通信连接与第二SIM卡相关。
请参考图2，其示出了本申请实施例提供的实现双卡双待双通的通信方法的应用场景实例示意图。其中，如图2所示的用户A的终端110可以为上述支持DR-DSDS的终端，该终端110中可以安装两个SIM卡：SIM卡1和SIM卡2。终端110中的SIM卡1可以为终端110的主卡，SIM卡2可以为终端110的副卡，或者终端110中的SIM卡2可以为终端110的主卡，SIM卡1可以为终端110的副卡。
其中，用户B使用终端120向终端110的SIM卡1发起语音寻呼请求后，用户A可以使用终端110通过终端110的SIM卡1与持有终端120的用户B进行语音通话。如图2所示，在用户A使用终端110通过终端110的SIM卡1与持有终端120的用户B进行语音通话过程中，用户C可能会使用终端130向终端110的SIM卡2发起语音寻呼请求，请求通过终端110的SIM卡2与持有终端110的用户A进行语音通话。
本申请实施例提供的实现双卡双待双通的通信方法可以在上述应用场景中，在不对用户A与用户B的语音通话质量造成较大影响的前提下，在终端110上接入终端130的来电请求，即在终端110上进行SIM卡2的来电提醒，以便于用户可以选择“拒接SIM卡2的来电，继续进行SIM卡1的语音通话”，或者选择“挂断SIM卡1的语音通话，转而接听SIM卡2的语音通话”，或者选择“保留SIM卡1的语音通话，接听SIM卡2的语音通话”。
举例来说，本申请实施例中的来电提醒可以包括以下一种或多种提醒方式：如终端响铃、终端用户界面显示用户C来电、终端振动、终端闪光灯闪光等。
示例性的，本申请实施例提供的支持DR-DSDS的终端的两张SIM中的每张SIM卡均可以为支持全球移动通信系统(Global System for Mobile Communication，GSM)制式、通用移动通信系统(Universal Mobile Telecommunications System，UMTS)制式、时分同步码分多址(Time Division-Synchronous Code Division Multiple Access，TD-SCDMA)制式、长期演进(Long Term Evolution，LTE)制式、码分多址(Code Division Multiple Access，CDMA)制式等制式中的任意一种制式的SIM卡。
例如，如图1或图2所示的终端110的SIM卡1和SIM卡2均可以为支持LTE制式的SIM卡。终端110通过SIM卡1与终端120之间的语音通信可以为(Voice over LTE，VoLTE)业务。终端通过SIM卡2与终端130之间的语音通信可以为VoLTE业务。
或者，如图1或图2所示的终端110的SIM卡1可以为支持LTE制式的SIM卡，终端110通过SIM卡1与终端120之间的语音通信可以为VoLTE业 务。如图1或图2所示的终端110的SIM卡2可以为支持GSM制式的SIM卡。终端110通过SIM卡2与终端130之间的语音通信可以为电路交换(Circuit Switched，CS)域业务。
或者，如图1或图2所示的终端110的SIM卡1和SIM卡2可以均为支持GSM制式的SIM卡。终端110通过SIM卡1与终端120之间的语音通信，以及终端110通过SIM卡2与终端130之间的语音通信均可以为CS域业务。
其中，终端110的数据业务可以在SIM卡1上，也可以在SIM卡2上；或者，终端110的SIM卡1和SIM卡2都可以进行终端110的数据业务传输。
在上述终端110的SIM卡、终端120的SIM卡以及终端130的SIM卡均为支持LTE制式的SIM卡的情况下，图3示出了本申请实施例提供的通信系统的结构。如图3所示，该通信系统包括服务网关(Serving GW，SGW)30、与SGW 30通过网络连接的移动性管理实体(Mobility Management Entity，MME)31、与MME 31通过网络连接的至少一个演进型基站(evolved Node B，eNB)、以及每个eNB连接的至少一个终端。结合图2，图3中示出了eNB 111、eNB 112、eNB 121以及eNB 131，终端110与eNB 111和eNB 112均连接，终端120与eNB 121连接，终端130与eNB 131连接。
SGW 30主要负责用户面处理，负责数据包的路由和转发等功能，支持第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)不同接入技术的切换。对每一个与演进分组系统(Evolved Packet System，EPS)相关的终端，在一个时间点上，都有一个SGW为之服务。MME 31主要负责移动性管理、承载管理、用户的鉴权认证、SGW的选择等功能等。
以终端110的SIM卡2为例，当网络侧出现对终端110的SIM卡2的下行数据或者下行信令，且该终端110的SIM卡2未与网络侧建立无线连接链路时，SGW 30向MME 31发送携带用于指示终端110的SIM卡2的优先级的第一信息的第一消息(如：第一消息为下行数据通知(Downlink Data Notification，DDN)消息、创建承载请求(Create Bearer Request)、或更新承载请求(Update Bearer Request))，指示MME 31向该终端110的SIM卡2的TA List中的基站(如eNB 112)发送通知消息。MME 31在接收到携带有第一信息的第一消息后，根据第一信息确定终端110的SIM卡2的优先级，并在终端110的SIM卡2的优先级大于预设等级的情况下，向eNB 112发送携带第三标识(第三标识表示第二业务)的通知消息。eNB 112在接收到携带第三标识的通知消息后，向终端110发送携带第一标识(第一标识表示第二业务)的寻呼请求，请求建立与终端110的SIM卡2相关的第二通信连接。相应的，终端110在确定寻呼请求携带第一标识的情况下，响应该寻呼请求。
需要说明的是，图3所示的通信系统中的终端也可以为仅仅包括一个SIM卡接口的终端，即仅仅安装有一个SIM卡的终端。
对于仅仅安装有一个SIM卡的终端(如终端A)而言，当网络侧出现对终端A的下行数据或者下行信令，且该终端A未与网络侧建立无线连接链路时，SGW 30向MME 31发送携带用于指示终端A的优先级的第一信息的第 一消息，指示MME 31向该终端A的TA List中的基站发送通知消息。MME 31在接收到携带有第一信息的第一消息后，根据第一信息确定终端A的优先级，并在终端A的优先级大于预设等级的情况下，向终端A的TA List中的基站发送携带第三标识的通知消息。该基站在接收到携带第三标识的通知消息后，优先寻呼终端A。
图4示出了本申请实施例提供的一种LTE网络中的支持DR-DSDS的终端的结构。如图4所示，该终端400可以包括：第一SIM卡接口410、第二SIM卡接口420、与第一SIM卡接口410和第二SIM卡接口420分别耦合的管理器440、与管理器340耦合的BBP 430(即处理器)，BBP 430连接收发器450。

其中，BBP 430中包括常用时间单元(Common Time Unit，CTU)。该CTU中包括用于判断上行数据包的发射优先级的仲裁器。
作为示例，在LTE网络中，终端400可以采用混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)协议向网络设备发送上行数据包。这样，即使管理器440向BBP 430发送的SIM卡(如SIM卡2)的上行数据包没有及时传输，也可以按照HARQ协议重传该上行数据包。
如图4所示，管理器440可以采用HARQ协议，向BBP 430发送SIM卡1和SIM卡2的无线链路层控制协议(Radio Link Control，RLC)队列中的上行数据包(prio)。BBP 430可以接收到管理器340发送的各种数据包，如SIM卡1发送的上行语音包，SIM卡2发送的上行信令包等。BBP 430按照各个上行数据包在射频Tx通路上的发射优先级，占用射频Tx通路向网络设备发送上行数据包。

如图5所示，手机500还可以包括耦合到编解码器CODEC 540的扬声器541和麦克风542。图5还指明了管理器550可以耦合到处理器510，且耦合到与收发器590进行通信的调制解调器580。其中，收发器590与一个或多个天线连接。图5中仅示出了一个天线的实例。
在特定的实施例中，收发器590与多个天线连接，调制解调器580支持分集，其中多个天线中的一个天线是主天线，另外的天线是辅天线。
收发器590可以为RF电路，该RF电路可用于收发信息或通话过程中，信号的接收和发送，可以将基站的下行信息接收后，给处理器510处理；另外，将涉及上行的数据发送给基站。通常，RF电路包括但不限于天线、至少一个放大器、收发信机、耦合器、低噪声放大器、双工器等器件。此外，RF电路还可以通过无线通信与网络和其他移动设备通信。所述无线通信可以使用任一通信标准或协议，包括但不限于全球移动通讯系统、通用分组无线服务、码分多址、宽带码分多址、长期演进、电子邮件、短消息服务等。在本申请实施例中，图5所示的收发器590中可以包括两路射频Rx通路和一路射频Tx通路(图5所示的射频Tx通路、射频Rx1通路和射频Rx2通路)。
其中，存储器560可用于存储软件程序及数据。处理器510通过运行存储在存储器560的软件程序及数据，从而执行手机500的各种功能以及数据处理。例如，如图5所示，存储器560中保存有指令561和发射优先级信息562。指令561可以由处理器510执行。例如，指令561可以包括可由处理器510执行，以在调制解调器580的主信号输入端接收与SIM卡1 553相关通信数据的指令。其中，可以经由收发器590的主RF路径，即Rx1，将上述“与SIM卡1 553相关通信数据”路由到调制解调器580的主信号输入端(图5中未示出)。指令561包括可由处理器510执行，以在调制解调器580的辅信号输入端接收与SIM卡2 554相关通信数据的指令。其中，可以经由收发器 590的辅RF路径，即Rx2，将上述“与SIM卡2 554相关通信数据”路由到调制解调器580的辅信号输入端(图5中未示出)。
上述存储器560可主要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、至少一个功能所需的应用程序(比如声音播放功能、图像播放功能等)等；存储数据区可存储根据手机500的使用所创建的数据(比如音频数据、电话本等)等。此外，存储器560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、或其他易失性固态存储器件。在以下实施例中，存储器560存储有使得手机500能运行的操作系统，例如苹果公司所开发的

操作系统，谷歌公司所开发的

操作系统等。
输入设备570(如触摸屏)可用于接收输入的数字或字符信息，以及产生与手机500的用户设置以及功能控制有关的信号输入。具体地，输入设备570可以包括设置在手机500正面的触控面板，可收集用户在其上或附近的触摸操作(比如用户使用手指、触笔等任何适合的物体或附件在触控面板上或在触控面板附近的操作)，并根据预先设定的程式驱动相应的连接装置。可选的，触控面板可包括触摸检测装置和触摸控制器两个部分。其中，触摸检测装置检测用户的触摸方位，并检测触摸操作带来的信号，将信号传送给触摸控制器；触摸控制器从触摸检测装置上接收触摸信息，并将它转换成触点坐标，再送给处理器510，并能接收处理器510发来的指令并加以执行。此外，可以采用电阻式、电容式、红外线以及表面声波等多种类型实现触控面板。
显示器531(即显示屏)可用于显示由用户输入的信息或提供给用户的信息以及手机500的各种菜单的图形用户界面(Graphical User Inter face,GUI)。显示器531可包括设置在手机500正面的显示面板。其中，显示面板可以采用液晶显示器、发光二极管等形式来配置。
当触控面板检测到在其上或附近的触摸操作后，传送给处理器510以确定触摸事件，随后处理器510根据触摸事件的类型在显示面板上提供相应的视觉输出。虽然在图5中，触控面板与显示面板是作为两个独立的部件来实现手机500的输入和输入功能，但是在某些实施例中，可以将触控面板与显示面板集成而实现手机500的输入和输出功能，集成后的触控面板与显示面板可以简称为触摸显示屏。
在另外的一些实施例中，上述触控面板还可以设置有压力感应传感器，这样用户在上述触控面板上进行触摸操作时，触控面板还能检测到该触摸操作的压力，进而手机500能够更准确地检测该触摸操作。
手机500还可以包括至少一种传感器543，比如光传感器、运动传感器以及其他传感器。具体地，光传感器可包括环境光传感器及接近传感器，其中，环境光传感器可根据环境光线的明暗来调节显示面板的亮度，接近光传感器设置在手机500的正面，当在手机500移动到耳边时，根据接近光传感器的检测，手机500关闭显示面板的电源，这样手机500可以进一步节省电量。作为运动传感器的一种，加速计传感器可检测各个方向上(一般为三轴) 加速度的大小，静止时可检测出重力的大小及方向，可用于识别手机姿态的应用(比如横竖屏转化、相关游戏、磁力计姿态校准)、振动识别相关功能(比如计步器、敲击)等；至于手机500还可配置的陀螺仪、气压计、湿度计、温度计、红外线传感器等其他传感器，在此不再赘述。
CODEC 540、扬声器541，麦克风542可提供用户与手机500之间的音频接口。CODEC 540可将接收到的音频数据转换后的电信号，传输到扬声器541，由扬声器541转换为声音信号输出；另一方面，麦克风542将收集的声音信号转换为电信号，由CODEC 540接收后转换为音频数据，再将音频数据输出至RF电路510以发送给比如另一手机，或者将音频数据输出至存储器560以便进一步处理。
处理器510是手机500的控制中心，利用各种接口和线路连接整个手机的各个部分，通过运行或执行存储在存储器560内的软件程序，以及调用存储在存储器560内的数据，执行手机500的各种功能和处理数据，从而对手机进行整体监控。在一些实施例中，处理器510可包括一个或多个处理单元；处理器510还可以集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作系统、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器510中。
上述手机500还可以包括蓝牙模块和Wi-Fi模块。蓝牙模块用于通过蓝牙这种短距离通讯协议来与其他设备进行信息交互。例如，手机500可以通过蓝牙模块与同样具备蓝牙模块的可穿戴电子设备(例如智能手表)建立蓝牙连接，从而进行数据交互。Wi-Fi属于短距离无线传输技术，手机500可以通过Wi-Fi模块帮助用户收发电子邮件、浏览网页和访问流媒体等，它为用户提供了无线的宽带互联网访问。
手机500还包括给各个部件供电的电源591(比如电池)。电源可以通过电源管理系统与处理器510逻辑相连，从而通过电源管理系统实现管理充电、放电、以及功耗等功能。可以理解的是，在以下实施例中，电源591可以用于给显示面板及触控面板供电。以下实施例中的方法均可以在具有上述硬件结构的手机500中实现。
本申请实施例中与支持DR-DSDS的终端通信的无线接入网设备可以为基站。下面结合图6对基站的各个构成部件进行具体的介绍。如图6所示，基站包括：基带单元(Base Band Unit，BBU)、射频拉远单元(Radio Remote Unit，RRU)和天线，BBU和RRU之间可以用光纤连接，RRU再通过同轴电缆及功分器(耦合器)连接至天线，一般一个BBU可以连接多个RRU。
RRU可以包括4个模块：数字中频模块、收发信机模块、功放模块和滤波模块。数字中频模块用于光传输的调制解调、数字上下变频、数模转换等；收发信机模块完成中频信号到射频信号的变换；再经过功放模块放大以及滤波模块滤波后，将射频信号通过天线发射出去。
BBU用于完成Uu接口(即终端设备与基站之间的接口)的基带处理功能(编码、复用、调制和扩频等)、无线网络控制器(Radio Network Controller， RNC)和基站之间的逻辑接口的接口功能、信令处理、本地和远程操作维护功能，以及基站系统的工作状态监控和告警信息上报功能等。
如图7所示，图3中的MME 30包括通信接口70、处理器71和存储器72。其中，通信接口70、处理器71与存储器72之间通过系统总线73连接，并完成相互间通信。
通信接口70用于与其他设备或通信网络通信，如以太网，WLAN等。
存储器72用于存储终端的上下文，还可以用于存储软件程序以及应用模块，处理器71通过运行存储在存储器72的软件程序以及应用模块，从而执行MME 30的各种功能应用以及数据处理。
存储器72可主要包括存储程序区720和存储数据区721，其中，存储程序区720可存储操作系统、至少一个功能所需的应用程序，比如发送通知消息等；存储数据区721可存储终端的上下文。
其中，存储器72可以包括易失性存储器(Volatile Memory)，例如随机存取存储器(Random-Access Memory，RAM)；该存储器也可以包括非易失性存储器(non-volatile memory)，例如只读存储器(Read-Only Memory，ROM)，快闪存储器(Flash Memory)，硬盘(Hard Disk Drive，HDD)、固态硬盘(Solid-State Drive，SSD)、磁盘存储介质或者其他磁存储设备、或者能够用于携带或存储具有指令或数据结构形式的期望的程序代码并能够由远端设备存取的任何其他介质，但不限于此。
存储器72可以是独立存在，通过系统总线73与处理器71相连接。存储器72也可以和处理器71集成在一起。
处理器71是MME 30的控制中心。处理器71利用各种接口和线路连接整个么么30的各个部分，通过运行或执行存储在存储器72内的软件程序和/或应用模块，以及调用存储在存储器72内的数据，执行MME 30的各种功能和处理数据，从而对MME 30进行整体监控。
在具体实现中，作为一种实施例，处理器71可以包括一个或多个CPU，例如图7中的处理器71包括CPU 0和CPU 1。
系统总线73可以是外设部件互连标准(英文：Peripheral Component Interconnect，简称：PCI)总线或扩展工业标准结构(英文：Extended Industry Standard Architecture，简称：EISA)总线等。
系统总线73可以分为地址总线、数据总线、控制总线等。本申请实施例中为了清楚说明，在图7中将各种总线都示意为系统总线73。
现对本申请实施例提供的实现双卡双待双通的通信方法进行详细说明。
图8为本申请实施例提供的实现双卡双待双通的通信方法的流程示意图，该实现双卡双待双通的通信方法可以应用于图2所示的应用场景中或者应用于图3所示的通信系统中。
本实施例以图2所示的应用场景，无线接入网设备为eNB，第一业务和第二业务均为语音通话为例进行说明。这样，第一通信连接是指与SIM卡1 相关的语音通话，第二通信连接是指与SIM卡2相关的语音通话。
如图8所示，本申请实施例提供的实现双卡双待双通的通信方法如下。
S801、终端110通过SIM卡1与终端120进行语音通信。
可以理解，在终端110通过SIM卡1与终端120进行语音通信的过程中(即终端110处于第一通信连接时)，因为终端110的SIM卡1处于通话状态，终端110向基站111发送第一通信连接的语音包。因此，终端110的SIM卡1通过处理器占用终端110中的Tx射频资源(即射频Tx通路)。
S802、终端130向基站131发送用于呼叫终端110的SIM卡2的呼叫请求。
S803、基站131在接收到S802中的呼叫请求后，请求核心网设备寻呼被叫终端(即终端110的SIM卡2)。
具体的，基站131在接收到呼叫请求后，经由MME 31向SGW 30转发该呼叫请求。
S804、核心网设备向基站112发送携带第三标识的通知消息，该通知消息用于指示基站112寻呼终端110的SIM卡2。
具体的，SGW 30在接收到上述呼叫请求，并确定终端110的SIM卡2未与网络侧建立无线连接链路后，向MME 31发送携带用于表示终端110的SIM卡2的优先级的第一信息的第一消息(本申请实施例中的第一消息可以为创建承载请求)，指示MME 31向终端110的SIM卡2的TA List中的基站(如eNB 112)发送通知消息。这里，第一信息可以为分配和保留优先级(Allocation And Retention Priority，ARP)。
MME 31在接收到携带第一信息的第一消息后，根据第一信息确定终端110的SIM卡2的优先级是否高于预设等级。在终端110的SIM卡2的优先级高于预设等级的情况下，MME 31向基站112发送携带第三标识的通知消息，指示基站112寻呼终端110的SIM卡2，并建立与终端110的SIM卡2的第二业务的连接。这里，第三标识用于指示第二业务。本申请实施例中的第二业务可以为语音通话，也可以为数据业务，本申请实施例对此不作具体限定。图8所示的实施例以第二业务为语音通话为例。
可选的，本申请实施例中携带第三标识的通知消息(本申请实施例中MME向基站发送的消息)可以是在现有的3GPP的36.413协议9.1.6所描述的MME向基站发送的消息的基础上进行修改的。
示例性的，本申请实施例中携带第三标识的通知消息如表1所示。现有的3GPP的36.413协议9.1.6所描述的MME向基站发送的消息中，寻呼优先级(Paging Priority)是可选的(Option，O)，且未给出寻呼优先级的取值和相应说明。本申请实施例中携带第三标识的通知消息中，Paging Priority是必选的(Mandatory，O)，寻呼优先级的取值为寻呼对象的优先级别，且某一终端的寻呼优先级的数值越小，说明该终端的寻呼优先级越高。
表1
Figure PCTCN2017091761-appb-000004
需要说明的是，携带第三标识的通知消息除了表1所示的内容以外，还可以包括其他内容，例如分配的重要性(Assigned Criticality)。
结合表1，当第二业务表示语音通话时，本申请实施例中的第三标识可 以为PrioLevel＝1。当第二业务表示数据业务时，本申请实施例中的第三标识可以为PrioLevel＝2。
S805、基站112在接收到核心网设备发送的通知消息后，向终端110发送寻呼(paging)请求。
具体的，在核心网设备发送的通知消息携带第三标识的情况下，基站112根据该通知消息向终端110发送携带用于表示第二业务的第一标识的寻呼请求，该寻呼请求用于请求建立与终端110的SIM卡2的第二业务的连接。
可选的，本申请实施例中携带第一标识的寻呼请求可以是在现有的3GPP的36.331协议所描述的paging消息的基础上进行修改的。
示例性的，在第二业务为语音通话的情况下，本申请实施例中携带第一标识的寻呼请求为：
Figure PCTCN2017091761-appb-000005
Figure PCTCN2017091761-appb-000006
可以看出，该示例中，本申请实施例中的第一标识用“call indication”表示。当Paging-v13xx-IEs中包括“call indication”时，说明该寻呼请求携带第一标识。
在核心网设备发送的通知消息未携带第三标识的情况下，基站112根据现有协议的规定，向终端110发送现有的寻呼请求。
S806、终端110接收基站112发送的对SIM卡2的寻呼请求。
在本实施例的S801中，终端110已经通过SIM卡1与终端120进行语音通信。终端110通过SIM卡1与终端120进行语音通信占用了终端110中的射频Rx1通路。那么终端110便可以通过射频Rx2通路接收对SIM卡2的寻呼请求。
对SIM卡2的寻呼请求为建立第二通信连接的寻呼请求，该第二通信连接与SIM卡2相关。一般的，对SIM卡2的寻呼请求可以为语音的寻呼请求，也可以为其他业务的寻呼请求。例如，对SIM卡2的寻呼请求可以短信业务的寻呼请求。
S807、终端110判断寻呼(paging)请求是否携带用于表示第二业务的第一标识。
一般而言，终端在接收到寻呼请求后，可以响应该寻呼请求向基站发送RRC信令，以便于可以与基站建立RRC连接，执行该寻呼请求对应的业务。 但是，在“当终端110的SIM卡1处于通话状态时，该终端110接收到对SIM卡2的寻呼请求”的场景下，如果终端110响应该寻呼请求，占用射频Tx通路向网络设备发送RRC信令，则会因为RRC信令占用射频Tx通路，导致终端110待发送的SIM卡1的语音包延迟发送，影响通话卡(SIM卡1)的语音通信质量。
但是，终端110在执行SIM卡1的语音业务的过程中，不会一直占用射频Tx通路发送SIM卡1的语音包。即终端110在SIM卡1处于通话状态时，会有一些空闲时段在射频Tx通路上不传输SIM卡1的语音包。例如，每个子帧中都会有一段时间(简称空闲时段)，终端110在该空闲时段内，在射频Tx通路上不传输SIM卡1的语音包。
例如，本申请实施例这里以时分双工(Time Division Duplexing，TDD)LTE网络为例，请参考表2，其示出了TDD-LTE网络中的上下行时隙配比表实例。
表2
Figure PCTCN2017091761-appb-000007
如表2所示，TDD-LTE网络可以包括7种上下行时隙配比(Uplink-Downlink Configuration，UL-DL Configuration)。表2所示的7种UL-DL Configuration中，UL-DL(0)、UL-DL(1)、UL-DL(2)和UL-DL(6)的上下行子帧切换周期(Switch-point periodicty)为5ms，UL-DL(3)、UL-DL(4)和UL-DL(5)的上下行子帧切换周期为10ms。其中，表2中的“U”用于表示传输上行数据(如上行语音包)的时隙，“D”用于表示传输下行数据的时隙。
由表2所示的7种上下行时隙配比可知，上行数据(如上行语音包)仅在一个子帧中的部分时隙(即上行时隙“U”)传输，而其他时隙不会传输上行数据(如上行语音包)。例如，在UL-DL(2)中，只有时隙2和时隙7用于传输上行数据(如上行语音包)，而其他时隙并不传输上行数据。
由此可见，每个子帧中都会有一段时间(简称空闲时段)，在该空闲时段内，SIM卡1是不会在射频Tx通路上传输上行语音包的。因此，即使终端110的SIM卡2在上述空闲时段内使用终端110的射频Tx通路响应上述寻呼请求与基站112交互，建立RRC连接，也不会影响终端110的SIM卡1与终 端120的语音通信质量。
如此，为了降低终端110响应上述寻呼请求对SIM卡1的语音通信质量产生影响，本申请实施例中，终端110可以仅仅在该寻呼请求是请求建立与SIM卡1的语音通话的情况下，响应该寻呼请求。
相应的，终端110在接收到基站112发送的对SIM卡2的寻呼请求后，需判断该寻呼请求是否携带第一标识。
S808、在寻呼请求未携带第一标识的情况下，终端110保持SIM卡1与终端120之间的语音通话(即终端110继续处理第一通信连接)。
寻呼请求未携带第一标识说明该寻呼请求不是用于语音通话，终端110可继续保持SIM卡1与终端120之间的语音通话，对该寻呼请求不作响应，保证了SIM卡1与终端120之间的语音通话不受干扰。
S809、在寻呼请求携带第一标识的情况下，终端110响应该寻呼请求。
S810、终端110响应寻呼请求，向基站112发送RRC信令，基于SIM卡2与基站112建立RRC连接。
可选的，本申请实施例中终端110向基站112发送的RRC信令的格式与现有的RRC信令的格式相同。
可选的，本申请实施例中终端110向基站112发送的RRC信令在现有的RRC信令的基础上还添加了第二标识，该第二标识用于表示终端110主动请求建立语音通话链接。在这种场景中，网络侧设备优先为终端112建立语音通话链接，提高了终端设备110的SIM卡2的接通率。
示例性的，本申请实施例中终端110向网络设备发送的RRC信令为RRC连接请求，该RRC连接请求为：
Figure PCTCN2017091761-appb-000008
Figure PCTCN2017091761-appb-000009
该示例中，本申请实施例中的第二标识用“mt-Voicecall”表示。当EstablishmentCause中包括“mt-Voicecall”时，说明终端110主动请求建立语音通话链接。
S811、终端110接收到基站112发送的对SIM卡2的邀请(Invite)消息。
由于终端110在确定上述寻呼请求携带第一标识后，才向基站112发送RRC信令，因此基站112可向终端110发送Invite消息(即第二通信连接的Invite消息)。
S812、终端110与基站112交互SIP信令。
S813、终端110接收基站112发送的SIM卡2的来电信息。
其中，当终端110从基站112获取到来电信息后，本申请一些实施例的方法还可以包括S814：
S814、终端110进行SIM卡2的来电提醒。
举例来说，其中，终端110进行来电提醒包括：终端110采用以下一种或多种提醒方式进行来电提醒：终端110响铃、终端110在用户界面显示用户C来电、终端振动、终端闪光灯闪光等。
其中，用户根据来电提醒的提示，可以选择拒绝SIM卡2的来电请求，继续进行SIM卡1的语音通话。用户也可以选择挂断SIM卡1的语音通话，转而接听SIM卡2的语音通话。
示例性的，请参考图9，其示出了本申请实施例提供的一种终端通话界面实例示意图。在终端110通过SIM卡1与终端120(用户B)进行语音通话的过程中，假设终端110的通讯录中保存有用户B的联系方式，终端110则可以显示如图9A所示的用户图形界面(Graphical User Inter face，GUI)。如图9A所示的GUI中可以包括：来电用户信息(如“用户B”)、通话时间信息“如08:01”、静音图标901、拨号键盘图标902、免提图标903、添加通话图标904和通讯录图标905以及挂机图标906等图标。其中，图9A所示的各个图标的功能可以参考现有技术中相应图标功能的介绍，本申请实施例这里不再赘述。
在终端110的SIM卡1与终端120进行语音通话的过程中，如果终端110接收到接收到用户C对SIM卡2的来电，终端110在获取到SIM卡2的来电信息(如用户C的电话号码)后，终端110则可以显示如图9B所示的用户图形界面(Graphical User Interface，GUI)。如图9B所示的GUI中可以包括：SIM卡2的来电提醒信息(如“SIM卡2：用户C来电”)906、结束并接听图标907、继续并挂断图标908和信息图标909等图标。其中，图标907用于结束原通话(即SIM卡1上与用户B的通话)并接听新通话(即SIM卡2上与用户C的通话)。图标908用于继续原通话(即SIM卡1上与用户B的通话)并挂断新通话(即SIM卡2上与用户C的通话)。信息图标909用于进入信息编辑窗口，以向终端130(即用户C)发送“稍后联系您！”、“会议中，稍后联系！”等消息。在另一些实施例中，终端110在获取到SIM卡2的来电信息(如用户C的电话号码)后，可以仅显示SIM卡2的来电提醒信息(如“SIM卡2：用户C来电”)906。在另一些实施例中，信息图标909可以在用户选择挂断原通话或新通话后再显示。
本申请实施例提供的实现双卡双待双通的通信方法，在终端110的SIM卡1处于通话状态时，终端110只有在接收到对SIM卡2的寻呼请求，且该寻呼请求携带表示第二业务的第一标识时，才会响应该寻呼请求，占用射频Tx资源发送RRC信令，与基站建立RRC连接。如此，终端110可以实现双卡双待双通，且降低了用于除第二业务以外的寻呼请求对SIM卡1的语音通话的干扰，保证了SIM卡1的语音通话质量。
综上而言，通过本方案，终端110可以在不影响通话卡的语音通话质量的前提下，可以实现终端的双卡双待双通，可以提高用户体验。
在一些实施例中，终端110可以在显示如图9所示的GUI之后，根据用户对如图9所示的GUI中的图标的选择，判断用户是否接听SIM卡2的来电请求。如图10所示，在S814之后，本申请实施例的方法还可以包括S815和S816。
S815、终端110判断用户是否接听SIM卡2的来电请求。
如果用户选择拒绝SIM卡2的来电请求，继续进行SIM卡1的语音通话，终端110则可以断开SIM卡2的RRC连接。如果用户选择挂断SIM卡1的语音通话，转而接听SIM卡2的语音通话，终端110则可以继续执行S814及其后续方法流程。
S816、终端110结束SIM卡1的语音通信，通过终端110的SIM卡2与终端130进行语音通信。
其中，在终端110通过SIM卡2与终端130进行语音通信的过程中，终端110的SIM卡2占用终端110中的Tx射频资源(即射频Tx通路)。
如图11A所示，当用户手指触摸或接近显示在如图11A所示的显示面板上的图标907时，则表示用户想要结束原通话(即SIM卡1上与用户B的通话)并接听新通话(即SIM卡2上与用户C的通话)，终端110的触控面板检测到在其上或附近的该触摸事件，传送给处理器410以确定触摸事件所对 应的指令，随后处理器410根据该指令指示显示面板显示如图11B所示的GUI，以便用户可以与用户C进行语音通信。如图11B-11C所示，终端110可以在显示如图11B所示的GUI一段时间(如3秒)后，可以显示如图11C所示的GUI。
在一些实施例中，终端110也可以不显示图11B所示的GUI，直接显示如图11C所示的GUI。
如图12A所示，当用户手指触摸或接近显示在如图12A所示的显示面板上的图标908时，则表示用户想要继续原通话(即SIM卡1上与用户B的通话)并挂断新通话(即SIM卡2上与用户C的通话)，终端110的触控面板检测到在其上或附近的该触摸事件，传送给处理器410以确定触摸事件所对应的指令，随后处理器410根据该指令指示显示面板显示如图12B所示的GUI，以便用户可以继续与用户B进行语音通信。如图12B-12C所示，终端110可以在显示如图12B所示的GUI一段时间(如2秒)后，可以显示如图12C所示的GUI。
在一些实施例中，终端110也可以不显示图12B所示的GUI，直接显示如图12C所示的GUI。
可选的，用户根据来电提醒的提示，还可以选择保留SIM卡1的语音通话(SIM卡1的语音通话被暂停挂起)，接听SIM卡2的语音通话。
示例性的，终端110还可以在来电提醒的界面上显示用于“保留原通话并接听新通话”的选项。当用户选择保留原通话并接听新通话时，终端110则可以将原通话(SIM卡1与终端120的语音通话)挂起，并接听新通话(SIM卡2与终端130的语音通话)，即控制SIM卡2暂时占用射频Tx资源，以便于可以在结束新通话或者保留新通话后，继续接听原通话。其中，被保留(即挂起hold)的语音通话对应的SIM卡发生的上行数据包多为空包。
示例性的，结合图11A所示的终端通话界面实例，当终端110的SIM卡1与终端120进行语音通话的过程中，如果SIM卡2接收到用户C的来电，终端110在获取到SIM卡2的来电信息(如用户C的电话号码)后，如果终端110的通讯录中保存有SIM卡2来电的电话号码和用户C的信息，终端则可以显示如图13A所示的GUI。其中，如图13A所示的GUI中除了如图9B所示的图标906、图标907、图标908和图标909之外，还可以包括保留并接听图标910。
如图14所示，在S815之后，如果用户选择保留SIM卡1的语音通话，接听SIM卡2的语音通话，则可以继续执行S817。
S817、终端110保留SIM卡1与终端120的语音通信，通过SIM卡2与终端130进行语音通信。
其中，当SIM卡2的语音通话请求(即用户C的来电请求)比较重要，用户A必须要接听该用户C来电请求，并且用户A不愿挂断原通话时，该用户A可以选择上述保留并接听图标910，控制终端110将原通话(SIM卡1与终端120的语音通话)挂起，并接听新通话(SIM卡2与终端130的语音 通话)，即控制SIM卡2暂时占用射频Tx资源，以便于可以在结束新通话或者保留新通话后，继续接听原通话。
如图13B所示，当用户手指触摸或接近显示在如图13B所示的显示面板上的图标510时，则表示用户想要保留原通话(即SIM卡1上与用户B的通话)并接听新通话(即SIM卡2上与用户C的通话)，终端110的触控面板检测到在其上或附近的该触摸事件，传送给处理器410以确定触摸事件所对应的指令，随后处理器410根据该指令指示显示面板显示如图13C所示的GUI，以便用户可以将原通话挂起，并与用户C进行语音通信。
如图15A所示，当用户手指触摸或接近显示在如图15A所示的显示面板上的挂断图标506时，则表示用户想要结束新通话(即SIM卡2上与用户C的通话)并继续原通话(即SIM卡1上与用户B的通话)，终端110的触控面板检测到在其上或附近的该触摸事件，传送给处理器410以确定触摸事件所对应的指令，随后处理器410根据该指令指示显示面板显示如图15B所示的GUI，以便用户可以继续与用户B进行语音通信。如图15B-15C所示，终端110可以在显示如图13B所示的GUI一段时间(如2秒)后，可以显示如图15C所示的GUI。如图15C-15D所示，终端110可以在显示如图15C所示的GUI一段时间(如3秒)后，可以显示如图15D所示的GUI。
本申请实施例提供的实现双卡双待双通的通信方法，在终端110的SIM卡1处于通话状态时，终端110只有在接收到对SIM卡2的寻呼请求，且该寻呼请求携带表示第二业务的第一标识时，才会响应该寻呼请求，占用射频Tx资源发送RRC信令，与基站建立RRC连接。如此，终端110可以实现双卡双待双通，且降低了用于除第二业务以外的寻呼请求对SIM卡1的语音通话的干扰，保证了SIM卡1的语音通话质量。
