可以理解,不同的射频发射通路可能并发的发送数据,不同的射频接收通路可能并发的接收数据。
处理器101作为终端设备10的控制中心,可以包括一个或多个处理单元,利用各种类型的接口和线路连接终端设备10的其它组件,通过运行或执行计算机程序,实现终端设备所具有的各项功能。

可以理解,该手机还可能包括用于支持其实现特定功能的其它组件,这里不再对该手机还可能包括的其它各个组件及其进行赘述。
本申请实施例中,终端设备进行相关于第一SIM卡或者第二SIM卡的、基于VOLTE的语音业务,指的是该终端设备在用户的操作下,通过第一SIM卡或第二SIM卡与其他终端设备进行基于VOLTE的语音通话。
本申请实施例中,终端设备通过其中一张SIM卡进行基于VOLTE的第一语音业务的过程中,不仅需要占用TX发送一个或多个语音数据包,占用射频接收通路RX1接收一个或多个语音数据包;还可能需要占用TX发送一个或多个信令包,具体如相关于第一语音业务的调度请求(SR,scheduling request)包、确认应答(ACK,acknowledgement)包、信道质量指示(CQI,channel quality indicator)包、应答信息包,还可能需要占用其中一条RX1接收一个或多个相关于第一语音业务的信令包。
其中,语音数据包是指进行语音业务的过程中产生的、包含语音数据的数据包;业务数据包是指终端设备访问应用服务器或提供特定服务的电子设备时,与应用服务器或提供特定服务的电子设备交互的、包含业务数据的数据包。
本申请实施例中,终端设备对连接请求进行响应的具体过程,可能需要终端设备与一个或多个位于网络侧的设备进行一次或多次信息交互,这将在后续各个实施例中进行示例性描述。
本申请实施例中,如果终端设备处于休眠状态(RCC空闲态或非激活态),终端设备通常可以通过第一SIM卡驻留于5G网络的基站所管理的小区中、通过第一SIM卡驻留于第一LTE网络的基站所管理的小区中,以及通过第二SIM卡驻留于第二LTE网络的基站所管理的小区中。此时,终端设备可能通过RXn接收来 自5G网络的、相关于第一SIM卡的寻呼请求,或者通过RX1接收来自第一LTE网络的、相关于第一SIM卡的寻呼请求,或者通过RX2接收来自第二LTE网络的、相关于第二SIM卡的寻呼请求,进入非休眠状态。可以理解,终端设备接收的寻呼请求可以触发终端设备通过第一SIM卡或者第二SIM卡,与该5G网络、第一LTE网络或者第二LTE网络的网络设备之间建立RRC连接,使得终端设备进入非休眠状态(RCC连接态)。当终端设备处于非休眠状态时,终端设备可能通过第一SIM卡优先连接5G网络,以便用户通过5G网络进行数据业务;即在终端设备通过第一SIM卡连接到5G网络的情况下,终端设备并不一定会通过第一SIM卡连接到第一LTE网络。需要说明的是,终端设备通过第一SIM卡连接到5G网络,包括但不限于终端设备通过第一SIM卡与5G网络的基站之间建立RRC连接,比如还可能包括终端设备基于其与5G网络的网络设备之间已经建立的RRC连接,与5G网络的一个或多个用户面功能(UPF,user plane function)实体之间建立协议数据单元(PDU,protocol data unit)会话,使得终端设备可通过5G网络访问互联网。
总而言之,在用户使用终端设备的过程中,终端设备需要进行第一语音业务时,终端设备往往已经通过第一SIM卡连接到了5G网络,即通过第一SIM卡与终端设备建立并激活了其与5G网络之间的RRC连接并且通过第二SIM卡连接到了第二LTE网络。
本申请实施例中,5G网络和第一LTE网络的组网模式可以是独立组网。当5G网络和第一LTE网络独立组网时,终端设备可通过第一SIM卡接入5G网络或者接入第一LTE网络,即终端设备可通过第一SIM卡与5G网络的网络设备(比如基站)之间保持RRC连接,或者与第一LTE网络的网络设备之间保持RRC连接。
本申请实施例中,5G网络和第一LTE网络的组网模式还可以是非独立组网。当5G网络和第一LTE网络为非独立组网时,5G网络和第一LTE网络可以具有相同的核心网,即5G网络的无线接入网(NR,new radio)可以和第一LTE网络的无线接入网连接到相同的核心网,比如连接到5G核心网(5GC)或者分组核心网(EPC,evolved packet core)。此时,第一LTE网络的无线接入网所包含的一个第二基站可以作为主基站,5G网络的无线接入网所包含的一个第一基站可以作为辅基站,该主基站与该辅基站保持双链接(DC,dual connectivity);辅基站无需与终端设备之间交互RRC信令,仅需要主基站与终端设备之间交互RRC信令,即可使终端设备得知辅基站为其分配的接入信息以及主基站为其分配的接入信息,从而使得终端设备通过第一SIM卡与主基站、辅基站之间均保持RRC连接,即使得终端设备同时连接到5G网络和第一LTE网络。
相应的,在本申请实施例中,终端设备断开与5G网络之间的连接并通过第一SIM卡连接到第一LTE网络,本质上是指终端设备与5G网络的网络设备(比如基站)之间不再保持通过第一SIM卡与该网络设备建立的RRC连接,但要确保终端设备与第一LTE网络之间存在相关于第一SIM卡的RRC连接。终端设备如何断开与5G网络之间的连接并通过第一SIM卡连接到第一LTE网络,将会在后续 各个实施例中进行示例性描述。
下面结合图2对本申请实施例可能适用的一种应用场景进行示例性描述。如图2所示,用户A使用的终端设备10可以为可以在两个LTE网络下支持双收单发的手机,该终端设备10可以安装第一SIM卡和第二SIM卡;其中,第一SIM卡可以为预先指定的用于支持终端设备10进行数据业务的主卡,第二SIM卡可以为预先指定的副卡,终端设备10可以通过第一SIM卡连接到5G网络以支持终端设备10进行数据业务,即通过第一SIM卡与5G网络的基站401之间保持RRC连接;此时,终端设备10可以通过第二SIM卡驻留于第二LTE网络的基站所管理的小区中,或者终端设备可能已经通过第二SIM卡与第二LTE网络的基站所管理的小区建立了RRC连接。
当用户A需要使用终端设备10与用户C使用的终端设备30进行语音业务时,终端设备10断开其与5G网络之间的连接并连接到第一LTE网络,即不再保持终端设备10与基站401之间的RRC连接,并且与第一LTE网络的一个基站501之间建立或激活RRC连接;之后,终端设备10即可通过包含基站501、基站502的第一LTE网络,与终端设备30之间进行相关于第一SIM卡的、基于VOLTE的第一语音业务。
在终端设备10进行第一语音业务的过程中,终端设备10通过第一SIM卡和第二SIM卡,同时连接到满足LTE网络制式的两个LTE网络中;当用户B使用的终端设备20需要与用户A使用的终端设备10进行相关于第二SIM卡的语音业务时,终端设备20可通过与其建立RRC连接的基站602,发送用于请求终端设备10进行语音业务的INVITE消息;此时,终端设备10通过基站601向终端设备10发送连接请求(比如,寻呼请求或者INVITE消息);终端设备10即可通过分时占用终端设备10的射频发射通路TX,对接收的连接请求进行响应,比如通过第二SIM卡与第二LTE网络的基站601之间建立RRC连接并进一步交互会话初始协议(SIP,session initiation protocol)信令;之后,网络设备10即可接收到来自第二LTE网络的、相关于第二语音业务的来电信息。
可以理解,如图2所示的业务场景仅为示例,比如,基于VOLTE的第一语音业务还可能为相关于第二SIM卡的语音业务;此时,终端设备通过第一SIM卡、第二SIM卡,同时连接到第一LTE网络和第二LTE网络。当终端设备30需要与终端设备10进行相关于第一SIM卡的第二语音业务时,基站501可以直接向终端设备10发送INVITE消息而不是寻呼请求,终端设备10接收的INVITE消息,即为用于请求终端设备进行相关于第一SIM卡的语音业务的连接请求。
总而言之,本申请实施例中提供的技术方案,当终端设备需要进行相关于其中一张SIM卡的第一语音业务时,终端设备主动断开与5G网络之间的连接并通过第一SIM卡连接到第一LTE网络;如此,当接收到来自第二LTE网络的连接请求时,终端设备位于满足LTE网络制式的两个LTE网络中,终端设备能够在进行相关于其中一张SIM卡的第一语音业务的过程中,通过分时占用射频发射通路,对用于请求终端设备进行相关于另一张SIM卡的第二语音业务的连接请求进行响应,以便终端设备接收并向用户提供相关于另一张SIM卡的来电信息。
可以理解,终端设备对连接请求进行响应之后,用户则可对终端设备进行相应的操作,实现选择进行第二语音业务并终止第一语音业务,即接听相关于另一张SIM卡的来电并结束第一语音业务;或者对终端设备进行相应的操作以拒绝进行第二语音业务。即用户可以在使用其中一张SIM卡进行通话的过程中,得知相关于另一张SIM卡的来电信息,并且可以通过对终端设备进行操作以选择是否接听相关于另一张卡的来电,用户体验较好。
可以理解,VOLTE是一种应用于LTE网络的、基于IP的语音解决方案,可以支持语音业务和数据业务并发。通常的,第一SIM卡可能被用户设置为用于支持终端设备进行数据业务的主卡,当终端设备通过第一SIM卡连接到第一LTE网络之后,无论终端设备是否在进行相关于第一SIM卡的语音业务,终端设备均可通过第一LTE网络相应的数据业务。
下面结合对本申请实施例的技术方案进行更加详细的描述。
图3为本申请实施例中提供的一种通信方法的流程图。该通信方法可以应用于如图1、图2所示的终端设备10,该终端设备10包括第一射频接收通路RX1、第二射频接收通路RX2和第一射频发射通路TX,该终端设备还包括有第一SIM卡接口103和第二SIM卡接口104,所述第一SIM卡接口103用于与第一SIM卡通信,所述第二SIM卡接口104用于与第二SIM卡通信,所述终端设备10通过所述第一SIM卡连接到5G网络。如图3所示,该通信方法至少可以包括如下步骤31~步骤35。
首先,在步骤31,当所述终端设备需要进行第一语音业务时,断开所述终端设备与所述5G网络之间的连接,并通过所述第一SIM卡连接到第一LTE网络。
这里,第一语音业务可以相关于第一SIM卡或者相关于第二SIM卡。
在一种可能的实施方式中,第一语音业务可以是终端设备在用户的操作下主动发起的语音业务,即终端设备可以响应于用户对所述第一语音业务的请求操作,断开终端设备与5G网络之间的连接,并通过第一SIM卡连接到第一LTE网络。
在另一种可能的实施方式中,第一语音业务可以是其它设备向终端设备发起的语音业务,即终端设备可以在接收到用于请求终端设备进行第一语音业务的连接请求时,断开终端设备与5G网络之间的连接,并通过第一SIM卡连接到第一LTE网络。
在一个较为具体的示例中,终端设备可以在接收到用于请求其进行第一语音业务的INVITE消息时,断开终端设备与所述5G网络之间的连接,并通过第一SIM卡连接到第一LTE网络。
在一个更为具体的示例中,该INVITE消息可以来自5G网络或者第一LET网络。该INVITE消息来自5G网络时,该INVITE消息可以用于请求终端设备进行基于5G语音承载(VONR,voice over new radio)的第一语音业务;该INVITE消息来自第一LTE网络时,该INVITE消息可以用于请求终端设备进行基于EPSFB(evolved packet system fall back)的第一语音业务,或者用于请求终端设备进行基于VOLTE的第一语音业务。
本申请实施例中,终端设备至少可以通过如下各种实现方式中的任意一种, 实现断开终端设备与所述5G网络之间的连接并通过第一SIM卡连接到第一LTE网络。
实现方式1,请参考图4,5G网络和第一LTE网络的组网模式为非独立组网,5G网络和第一LTE网络可以共用第一LTE网络的EPC或者5G网络的5GC,第一LTE网络的无线接入网所包含的一个基站eNB可以作为主基站,5G网络的无线接入网所包含的一个基站gNB可以作为辅基站。eNB所覆盖的各个小区组成主小区组,gNB所覆盖的各个小区组成辅小区组,eNB和gNB双链接。终端设备10可通过与eNB交互RRC信令,使得终端设备10同时与gNB和eNB之间建立RRC连接,可以通过其与gNB之间建立的RRC交互语音数据包和业务数据包。
相应的,在终端设备10与第一LTE网络、5G网络满足如图4所示的系统框架的情况下,如图5所示,可通过如下步骤51~59,使得终端设备10从5G网络断开与5G网络之间的连接并通过第一SIM卡连接到第一LTE网络。
步骤51,终端设备10向第一LTE网络的eNB发送SCG失败信令。
步骤53,第一LTE网络的eNB响应于SCG失败信令,向5G网络的gNB发送相关于终端设备10的SCG失败消息。
步骤55,5G网络的gNB响应于SCG失败消息,释放其与终端设备10之间建立的RRC连接。
步骤57,5G网络的gNB向第一LTE网络的eNB发送应答信息。
步骤59,第一LTE网络的eNB响应于应答信息,向终端设备10发送RRC释放消息。
其中,RRC释放消息用于指示终端设备10基于该第一LTE网络的eNB与终端设备10之间的RRC连接,进行相关于第一SIM卡的语音业务和/或数据业务。即终端设备可在RRC释放消息的指示下,在后续过程中通过其与第一LTE网络的eNB之间建立的、相关于第一SIM卡的RRC连接,来接收和/或发送相关于第一语音业务的语音数据包以及相关于数据业务的业务数据包。
实现方式2,无论第一LTE网络和5G网络是否独立组网,在5G网络的NR中用于接入终端设备10的基站,均可与第一LTE网络中用于接入该终端设备10的基站连接。相应的,如图6所示,可通过如下步骤61~步骤66,使得终端设备断开与5G网络之间的连接并通过第一SIM卡连接到第一LTE网络。
步骤61,终端设备10向5G网络的第一基站发送信号测量报告。
其中,该第一基站是5G网络中与终端设备10建立了RRC连接的基站。
其中,信号测量报告至少用于指示第一基站相对于终端设备的信号质量不满足预设条件。
其中,信号测量报告还可以用于指示第一LTE网络的第二基站相对于终端设备10的信号质量满足预设条件。
步骤62,5G网络的第一基站向第一LTE网络的第二基站发送请求消息。
其中,该请求消息用于请求将该终端设备10切换到第一LTE网络的第二基站。
可以理解的,该接入请求中还可能包括第一SIM卡的相关信息,以便终端设备在后续过程中向第二基站发送确认消息时,得知发送确认消息的终端设备10是 否为第二基站允许接入的终端设备10。
步骤63,第一LTE网络的第二基站响应于请求消息,向5G网络的第一基站发送接入信息。
其中,该接入信息包括用于终端设备接入第二基站所需的信息,比如第二基站分配给终端设备的专用信道的相关参数。
步骤64,5G网络的第一基站向终端设备10发送切换指令。
其中,切换指令包含接入信息。
步骤65,终端设备10响应于切换指令,利用切换指令包括的接入信息更新终端设备10中存储的相关于第一SIM卡的接入信息。
步骤66,终端设备基于更新后的接入信息向第一LTE网络的第二基站发送确认消息。
其中,确认消息中可以携带第一SIM卡的相关信息,以便第一LTE网络接收到确认消息时,得知终端设备成功切换到第二基站,即得知终端设备已经完成建立其与第二基站之间的RRC连接。
实现方式2中,终端设备10无需与其他终端设备竞争第一LTE网络的资源,可快速接入第一LTE网络。
实现方式3:终端设备通过重选PLMN断开与5G网络之间的连接,并通过第一SIM卡连接到第一LTE网络。即终端设备主动释放其与5G网络之间建立的RRC连接,主动请求并完成建立其与第一LTE网络之间的RRC连接。
接着,在步骤33,当所述第一语音业务相关于所述第一SIM卡时,通过所述第一LTE网络进行基于VOLTE的所述第一语音业务,并接收来自所述第二LTE网络的第一连接请求。
其中,第一语音业务可以占用第一射频接收通路RX1和第一射频发射通路TX,终端设备可以通过第二射频接收通路RX2接收来自第二LTE网络的连接请求,该连接请求用于请求终端设备10进行基于VOLTE的第二语音业务,该第二语音业务相关于第二SIM卡,该连接请求可能为寻呼请求或者INVITE消息。
之后,在步骤35,通过分时占用所述射频发射通路,在进行所述第一语音业务的过程中对所述第一连接请求进行响应。
具体地,以第一语音业务相关于第一SIM卡,第一LTE网络为时分双工(TDD,time division duplexing)LTE网络为例,其可能具有如下表1所示的各种时隙配比。
表1
Figure PCTCN2020103076-appb-000003
Figure PCTCN2020103076-appb-000004
如表1所示,TDD-LTE网络可以包括多种时隙配比(Uplink-Downlink Configuration,UL-DL Configuration)。表1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 periodicity)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1中的“U”用于表示传输上行数据(如上行语音数据包)的时隙,“D”用于表示传输下行数据的时隙。
由表1可知,上行数据(如上行语音数据包)仅在一个子帧的部分时隙(即上行时隙“U”)传输,而其他时隙不会传输上行数据,对于不需要传输上行数据的各个时间段(简称空闲时段),在该空闲时段内,相关于第一SIM卡第一语音业务并不会占用射频发射通路TX上传输上行语音数据包。
相应的,终端设备通过第一LTE网络进行第一语音业务的过程中,可以在其对应的空闲时段内占用射频发射通路TX对RX2接收的连接请求进行响应,以便终端设备10接收来自第二LTE网络的、相关于第二SIM卡的来电信息。
为了保证第一语音业务的通话质量,还可以设置终端设备10进行第一语音业务时,所需要占用TX1发送的一个或多个第二数据包、终端设备10对连接请求进行响应所需发送的一个或多个第一数据包的优先级,比如设置每个第二数据包的优先级均高于第一数据包的优先级,在一个或多个第二数据包中,每个语音数据包的优先级均高于每个信令包的优先级,终端设备10按照优先级的高低,分时占用射频发射通路TX来发送这些各个数据包。
在一种可能的实施方式中,终端设备10的log日志中可以记录第一SIM卡和第二SIM卡发送和接收的各个数据包的信息。比如,log日志中可以记录第一SIM卡相关的所有上行数据包的类型、该第一SIM卡的名称、字节数等。
图7为本申请实施例提供的一种log日志中记录的第一SIM卡发送的数据包信息实例。如图7所示,假设第一SIM卡处于通话状态(即终端设备通过第一LTE网络进行相关于第一SIM卡的语音业务),相关于第一语音业务的语音数据包可以包括语音数据包Y0、语音数据包Y1、语音数据包Y2、语音数据包Y3和语音数据包Y4。其中,上述语音数据包Y0、语音数据包Y1、语音数据包Y2、语音数据包Y3和语音数据包Y4预计依次在T0时刻、T1时刻、T2时刻、T3时刻、T4时刻发送。
仍然以相关于第一语音业务的语音数据包的优先级,高于对连接请求进行响应所需发送的各个信令包的优先级为例,当终端设备接收到连接请求时,如果终端设备中存在待发送的相关于第一语音业务的语音数据包,终端设备可以延迟对其接收的连接请求进行响应;相应的,如果终端设备中不存在待发送的相关于第一语音业务的语音数据包,终端设备立即对其接收的连接请求进行响应。
结合上述表1,假设终端设备10采用表1所示UL-DL(2)的时隙配比方式进行第一SIM卡和第二SIM卡的语音业务。如图8A所示,在周期2的下行时隙“9-D”(即T7时刻),终端设备10在射频接收通路RX2接收到对第二SIM卡的连接请求,比如相关于第二SIM卡的寻呼请求或INVITE消息,下面将主要以连接请求 为寻呼(paging)消息。
应注意,当第一SIM卡处于通话状态时(即终端设备进行相关于第一SIM卡的语音业务时),如果终端设备10接收到对第二SIM卡的连接请求为寻呼请求,如图8A所示,终端设备10可以响应该寻呼请求,发送信令包X0和信令包X1(如RRC信令包)。
一般而言,无论TX上是否发送第一SIM卡的语音数据包,终端设备10都可以在接收到上述寻呼请求后,立即响应该寻呼请求,在TX上发送信令包X0和信令包X1。例如,如图7A中的“Tx(1)”所示,终端设备10可以在T7时刻接收到对第二SIM卡的寻呼请求时,立即响应该寻呼请求,在下一上行时隙(即周期3的时隙“2-U”,T3时刻)发送信令包X0,并在下一上行时隙(即周期4的时隙“7-U”,T4时刻)发送信令包X1。随后,终端设备10可以在周期5的时隙“2-U”,T5时刻)发送语音数据包Y3,在周期6的时隙“7-U”,T6时刻)发送语音数据包Y4。即终端设备10可以依次在T0时刻、T1时刻、T2时刻、T3时刻、T4时刻、T5时刻、T6时刻,占用TX发送语音数据包Y0、语音数据包Y1、语音数据包Y2、信令包X0、信令包X1、语音数据包Y3和语音数据包Y4。
但是,当第一SIM卡处于通话状态时,如果终端设备10接收到对第二SIM卡的寻呼请求,立即响应该寻呼请求,占用TX向第二LTE网络发送信令包X0和信令包X1,可能会导致第一SIM卡的语音数据包被延迟发送,影响第一SIM卡的语音通信质量。
为了保证第一SIM卡的语音通信质量,在一种可能的实施方式中,终端设备10可以在发送第一SIM卡的语音数据包(即终端设备进行第一语音业务的过程中所需发送的语音数据包)时,延迟响应上述寻呼请求。例如,如图8A中的“Tx(2)”所示,终端可以在T7时刻接收到对第一SIM卡的寻呼请求时,延迟响应该寻呼请求。如图8A中“Tx(2)”所示,终端设备10可以在下一上行时隙(即周期3的时隙“2-U”,T3时刻)发送语音数据包Y3,并在下一上行时隙(即周期4的时隙“7-U”,T4时刻)发送语音数据包Y4。随后,终端设备10可以在周期5的时隙“2-U”(即T5时刻,相比于T7时刻延时ΔT)发送信令包X0,在周期6的时隙“7-U”,T6时刻)发送信令包X1。即终端设备10可以依次在T0时刻、T1时刻、T2时刻、T4时刻、T5时刻、T6时刻,占用TX发送语音数据包Y0、语音数据包Y1、语音数据包Y2、语音数据包Y3、语音数据包Y4、信令包X0和信令包X1。
在另一种可能的实施方式中,假设终端设备10采用上述表1所示的UL-DL(2)的时隙配比方式进行相关于第一SIM卡的语音通信,采用表1所示的UL-DL(1)的时隙配比方式进行相关于SIM卡2的语音通信。
一般而言,无论射频TX通路上是否发送SIM卡1的语音数据包,终端110都可以在接收到上述连接请求(比如寻呼请求)后,立即响应该寻呼请求,在TX通路上发送信令包X0和信令包X1。例如,如图8B所示,在UL-DL(1)的周期2的下行时隙“9-D”(即T7时刻),终端设备10通过RX2接收到来自第二LTE网络的、对第二SIM卡的寻呼请求。终端可以在T7时刻接收到对第二SIM卡的寻呼请求时,立即响应该寻呼请求,在UL-DL(1)的周期3的时隙“2-U”(即T3 时刻)发送信令包X0,在UL-DL(1)的周期3的时隙“3-U”(即T4时刻)发送信令包X1。随后,终端110可以在UL-DL(2)的周期4的时隙“7-U”,T5时刻)发送语音数据包Y3,在UL-DL(2)的周期5的时隙“2-U”(即T6时刻)发送语音数据包Y4。
但是,当第一SIM卡处于通话状态时,如果终端设备10接收到对第二SIM卡的寻呼请求,立即响应该寻呼请求,占用TX向第二LTE网络发送信令包X0和信令包X1,则会导致第一SIM卡的语音数据包被延迟发送,会影响第一SIM卡的语音通信质量。
为了保证第一SIM卡的语音通信质量,在另一种可能的实施方式中,终端设备10可以在发送第一SIM卡的语音数据包(即终端设备10存在待发送的相关于第一语音业务的语音数据包)时,延迟响应上述寻呼请求。例如,如图8B中的“Tx(2)”所示,终端设备10可以在T7时刻接收到对第二SIM卡的寻呼请求时,延迟响应该寻呼请求,在UL-DL(2)的周期3的时隙“2-U”发送语音数据包Y3,在UL-DL(2)的周期4的时隙“7-U”(即T4时刻)发送语音数据包Y4。随后,终端110可以在UL-DL(1)的周期5的时隙“2-U”(即T5时刻,相比于T7时刻延时ΔT)发送信令包X0,在UL-DL(1)的周期5的时隙“3-U”,T6时刻)发送信令包X1。
示例性的,结合表1,假设终端采用表1所示的UL-DL(2)的时隙配比方式进行第一SIM卡和第二SIM卡的语音通信(即语音业务)。如图9A所示,在周期2的下行时隙“9-D”(即T7时刻),终端设备10通过RX2接收到来自第二LTE网络的、对第二SIM卡的寻呼请求(即请求终端设备进行相关于第二SIM卡的第二语音业务的连接请求)。此时,终端设备10不存在待发送的相关于第一语音业务的语音数据包。那么,终端设备10则可以收到在接收到该寻呼请求时,立即响应该寻呼请求,在TX通路上发送信令包X0和信令包X1。例如,如图9A所示,终端可以在T7时刻接收到对第二SIM卡的寻呼请求后,立即响应该寻呼请求,在下一上行时隙(即周期5的时隙“2-U”,T5时刻)发送信令包X0,并在下一上行时隙(即周期6的时隙“7-U”,T6时刻)发送信令包X1。
示例性的,假设终端采用表1所示的UL-DL(2)的时隙配比方式进行相关于第一SIM卡的语音业务,采用表1所示的UL-DL(1)的时隙配比方式进行相关于第二SIM卡的语音业务。如图9B所示,终端设备10可以在T7时刻接收到对SIM卡2的paging请求后,立即响应该寻呼请求,在UL-DL(1)的周期5的时隙“2-U”(即T5时刻)发送信令包X0,并在UL-DL(1)的周期5的时隙“3-U”(即T6时刻)发送信令包X1。
在一种可能的实施方式中,终端设备可能具有持续测量5G网络的信号质量的能力,为了避免终端设备10通过第一SIM卡连接到第一LTE网络之后,因5G网络的信号质量优于第一LTE网络的信号质量,导致终端设备10通过第一SIM卡重新连接到5G网络,在终端设备10接入第一LTE网络之后,终端设备10可以中止测量5G网络的信号质量。
如前所述,第一语音业务可以是终端设备在用户的操作下主动发起的、相关 于第一SIM卡或者第二SIM卡的语音业务,第一语音业务还可以是其它终端设备发起的、相关于第一SIM卡或者第二SIM卡的语音业务。下面对前述一种或多种发起形式的语音业务,对本申请实施例中提供的通信方法进行示例性描述。
以终端设备10在用户的操作下,向终端设备B主动发起相关于第一SIM卡的第一语音业务,实现在终端设备10通过第一SIM卡与终端设备B进行语音通话的过程,接收终端设备C向终端设备10发起的、相关于第二SIM卡的第二语音业务所对应的来电信息为例,如图10所示,本申请实施例的通信方法可以部分包括或全部包括如下步骤1001至步骤1009。
步骤1001,终端设备10响应于用户对相关于第一SIM卡的、请求与终端设备B进行第一语音业务的请求操作,断开与5G网络之间的连接并通过第一SIM卡接入第一LTE网络。
具体地,请求操作可以是用户对手机进行相应的操作,所产生的拨打安装于终端设备B中的一张SIM卡所对应的电话号码的操作。
步骤1002,终端设备10通过第一LTE网络与终端设备B进行相关于第一SIM卡的、基于VOLTE的第一语音业务。
其中,第一语音业务占用终端设备10的第一射频接收通路和射频发射通路。
需要说明的是,在步骤1002之前,终端设备10与第一LTE网络之间还可能执行,包括但不限于后续步骤1005至步骤1009相似的信息交互过程。
步骤1003,终端设备C向第二LTE网络发送相关于第二SIM卡的INVITE消息。
步骤1004,第二LTE网络响应于INVITE,向终端设备B发送相关于第二SIM卡的寻呼请求。
其中,该寻呼请求用于请求终端设备10与终端设备C进行相关于第二SIM卡的、基于VOLTE的第二语音业务。
步骤1005,终端设备10响应于寻呼请求,通过第二SIM卡与第二LTE网络交互RRC信令。
这里,终端设备10通过第二SIM卡与第二LTE网络交互RRC信令的过程,可以视为终端设备通过第二SIM卡接入第二LTE网络的过程,即终端设备10与第二LTE网络完成交互RRC信令之后,终端设备10实现了通过第二SIM卡接入第二LTE网络。
这里,由于终端设备10通过第一SIM卡接入了第一LTE网络,且终端设备10对寻呼消息进行响应的过程中,所需要发送的信令包(比如RRC信令包、应答信息等)的接收端(即第二LTE网络)也满足LTE网络制式,因此,终端设备10对寻呼消息进行响应而发送的一个或多个第一数据包,与终端设备10进行第一语音业务而发送的一个或多个第二数据包,可以分时占用终端设备10的射频发射通路。
可以理解的,步骤1005~步骤1007为终端设备10针对相关于第二SIM卡的寻呼进行响应的具体过程,整个响应过程不仅需要发送一个或多个信令包,还可能接收一个或多个信令包。相关于第二SIM卡的“寻呼请求”,可以视为用于请 求终端设备10通过第二SIM卡与终端设备C进行基于VOLTE的第二语音业务的连接请求。
步骤1006,第二LTE网络向终端设备10发送INVITE消息。
需要说明的是,第二LTE网络的网络设备(可能为位于第二LTE网络的一台代理服务器),可以在终端设备C发送的INVITE消息中插入该网络设备自身的地址(比如IP地址),将插入地址之后的INVITE消息发送至终端设备10,以便终端设备发送的应答信息能够到达第二LTE网络的网络设备。
步骤1007,终端设备10向第二LTE网络发送应答信息。
步骤1008,第二LTE网络向终端设备10发送相关于第二语音业务的来电信息。
比如,终端设备C通过其安装的一张SIM卡接入了第二LTE网络,第二LTE网络的网络设备(比如一台代理服务器)中可以维护该SIM卡的相关信息,比如该SIM卡所对应的电话号码、归属地等信息,这些信息可以作为相关于第二语音业务的来电信息被发送至终端设备10。
步骤1009,终端设备10响应于来电信息,进行来电提醒。
通常的,终端设备10在发送应答信息之后,即可进行振铃,通常在进行一次振铃之后,即可接收到来自第二LTE网络的来电信息。
示例性的,以第一语音业务是终端设备C发起的相关于第二SIM卡的语音业务,实现在终端设备10通过第二SIM卡与终端设备C进行语音通话的过程中,接收终端设备B向终端设备10发起的、相关于第一SIM卡的第二语音业务所对应的来电信息为例,如图11所示,本申请实施例的通信方法可以部分包括或全部包括如下步骤1101至步骤1110。
步骤1101,终端设备C向第二LTE网络发送相关于第二SIM卡的INVITE消息。
该INVITE消息,用于请求终端设备10通过其安装的第二SIM卡与终端设备C之间进行基于VOLTE的第一语音业务。
步骤1102,第二LTE网络响应于接收的INVITE消息,向终端设备10发送相关于第二SIM卡的寻呼请求。
步骤1103,终端设备10断开与5G网络之间的连接并连接到第一LTE网络。
步骤1104,终端设备10与第二LTE网络交互RRC信令,使得终端设备10通过第二SIM卡接入第二LTE网络。
步骤1105,终端设备通过第二LTE网络与终端设备C进行相关于第二SIM卡的、基于VOLTE的第一语音业务。
其中,第一语音业务占用终端设备10的第一射频接收通路和射频发射通路。
需要说明的是,在步骤1105之前,终端设备10除了与第二LTE交互RRC信令之外,终端设备10可能还需要与第二LTE网络之间进行一次或多次数据交互,包括但不限于执行与后续步骤1107至步骤1110相似的信息交互过程。
步骤1106,终端设备B向第一LTE网络发送相关于第一SIM卡的INVITE消息。
该INVITE消息,用于请求终端设备10通过其安装的第一SIM卡与终端设备B之间进行基于VOLTE的第二语音业务。
步骤1107,第一LTE网络向终端设备10发送INVITE消息。
可以理解的,相关于第一SIM卡的“INVITE消息”,可以视为用于请求终端设备10通过第一SIM卡与终端设备B进行基于VOLTE的第二语音业务的连接请求。
需要说明的是,第一LTE网络的网络设备(可能为位于第一LTE网络的一台代理服务器),可以在终端设备B发送的INVITE消息中插入该网络设备自身的地址(比如IP地址),将插入地址之后的INVITE消息发送至终端设备10,以便终端设备发送的应答信息能够到达第一LTE网络的网络设备。
步骤1108,终端设备10对其接收的INVITE消息进行响应,向第一LTE网络发送应答信息。
这里,由于终端设备10通过第一SIM卡接入了第一LTE网络,且终端设备10对寻呼消息进行响应的过程中,所需要发送的数据包(比如应答信息)的接收端(即第一LTE网络)也满足LTE网络制式,因此,终端设备10对INVITE消息进行响应而发送的一个或多个第一数据包,与终端设备10进行第一语音业务而发送的一个或多个第二数据包,可以分时占用终端设备10的射频发射通路。
步骤1109,第一LTE网络向终端设备10发送来电信息。
步骤1110,终端设备10响应于来电信息,进行来电提醒。
通常的,终端设备10在发送应答信息之后,即可进行振铃,通常在进行一次振铃之后,即可接收到来自第一LTE网络的来电信息。
在前述各个示例中,包括但不限于通过相应的界面来显示来电信息,以实现对来电提醒。其中,用于显示来电信息的界面中除了显示来电信息以外,还可以显示终端设备进行第一语音业务的通话时长、相关于第一语音业务的挂断图标、相关于第二语音业务的接听图标等。
相应的,用户还可以在显示来电信息的界面中执行相应的操作,选择是否进行第二语音业务。仍然以第一语音业务相关于第一SIM卡、第二语音业务相关于第二SIM卡为例,用户可以通过触发该挂断图标或者接听图标终止进行第一语音业务;并且,当用户选择触发接听图标时,终端设备可以通过第二LTE网络向发送表征连接成功的应答信息,当终端设备接收到来自第二LTE网络的ACK包时,终端设备即可通过第二LTE网络进行相关于第二SIM卡、基于VOLTE的第二语音业务。
可以理解的,用于显示来电信息的界面所包含的各个图标,以及用户对该界面中的各个图标进行触发而使得终端设备执行的响应,可参考现有技术,这里不再针对终端设备接收到相关于第二语音业务的来电信息之后,可能发生的相对于第一语音业务和第二语音业务的处理流程进行赘述。
在一种可能的实施方式中,终端设备也可能在未接收到用于请求终端设备进行相关于另一张SIM卡的第二语音业务的连接请求之前,无论执行基于VOLTE、基于NR或者其它各种形式的第一语音业务,终端设备均不会断开与5G网络之间 的连接并连接到第一LTE网络。当且仅当接收到来用于请求终端设备进行相关于另一张SIM卡的第二语音业务的连接请求之后,终端设备才断开其连接的5G网络并通过第一SIM卡连接到第一LTE网络。
前述各个实施例中,终端设备进行相关于第一SIM卡的语音业务时,断开了其自身与5G网络之间的连接,使得终端设备在进行第一语音业务的过程中,5G专用通道RXn和TXn被闲置。如果终端设备在进行语音业务的过程中同时进行数据业务,终端设备进行数据业务时,可能需要传输大量的业务数据包以及与该数据业务相关的信令包。相应的,终端设备并发的进行数据业务和语音业务时,则可能导致一部分需要通过主通道的射频发送通路TX进行传输的数据包,无法被及时传输至网络侧;从而导致终端设备不能及时针对连接请求进行响应,或者影响第一语音业务的通信质量,或者导致数据业务无法高效的进行,影响用户体验。
为了进一步的提高用户体验,本申请实施例中还提供了另一种通信方法,该通信方法可以应用于如图1、图2所示的终端设备10,所述终端设备10包括第一射频发射通路TXn、第二射频发射通路TX、第一SIM卡接口103和第二SIM卡接口104,所述第一SIM卡接口103用于与第一SIM卡通信,所述第二SIM卡接口104用于与第二SIM卡通信,所述终端设备10通过所述第一SIM卡连接到5G网络和第一LTE网络。如图12所示,该通信方法至少可以包括如下步骤121~步骤125。
在步骤121,通过所述第一LTE网络进行基于VOLTE的第一语音业务,所述第一语音业务相关于所述第一SIM卡。
如前所述,5G网络和第一LTE网络的组网模式可以是非独立组网,在5G网络和第一LTE网络非独立组网的情况下,终端设备可通过其安装的第一SIM卡同时连接到第一LTE网络和5G网络。
在一种可能的实施方式中,当其他设备请求终端设备10进行相关于第一SIM卡的第一语音业务时,如果该连接请求来自第一LTE网络,终端设备10则对其进行响应;如果该连接请求来自5G网络,终端设备10则可不必对其进行响应。
在另一种可能的实施方式中,终端设备响应于用户对第一语音业务的请求操作,向第一LTE网络发送连接请求。
如此,使得终端设备可以通过第一LTE网络,进行相关于第一SIM卡的、基于VOLTE的语音业务。
可以理解的,终端设备10进行第一语音业务时,进行第一语音业务所需发送的各个语音数据包以及相关于该第一语音业务的信令包,可通过第二射频发射通路TX发送至第一LTE网络;进行第一语音业务所需接收的各个语音数据包以及相关于该第一语音业务的信令包,可以通过第一射频接收通路RX1从第一LTE网络接收。
步骤123,在进行所述第一语音业务的过程中,通过所述第一射频发射通路向所述5G网络发送相关于数据业务的一个或多个业务数据包,并接收来自所述第二LTE网络的连接请求,所述连接请求用于请求所述终端设备进行基于VOLTE的第二语音业务,所述第二语音业务相关于所述第二SIM卡。
可以理解的,终端设备进行数据业务时,可能不仅需要通过第一射频发射通路向5G网络发送业务数据包,还可能需要通过第一射频发射通路向5G网络发送相关于该数据业务的信令包。
可以理解的,终端设备进行数据业务时,还可能通过第三射频接收通路RXn从5G网络接收相关于该数据业务的业务数据包和信令包。
步骤125,通过分时占用所述第二射频发射通路,在进行所述第一语音业务的过程中,对所述第一连接请求进行响应。
如前所述,终端设备在支持LTE网络制式的第一LTE网络下进行相关于第一SIM的第一语音业务,而该连接请求用于请求终端设备在支持LTE网络制式的第二LTE网络下进行相关于第二SIM卡的第二语音业务;因此,这里可以通过前述任意一个实施例中提供的,通过分时占用射频发射通路,在进行第一语音业务的过程中对连接请求进行响应的技术方案,实现步骤125。
在上述实施例中,终端设备可以在进行相关于其中一张SIM卡的语音业务的过程中,针对用于请求终端设备进行相关于另一张SIM卡的语音业务的连接请求进行响应;而且,终端设备并发的进行语音业务和数据业务的过程中,可以分别通过不同的射频发射通路,向两个不同的网络分别传输与语音业务相关数据包以及与数据业务相关的业务数据包,使得终端设备需要发送的各个数据包能够更为快速的传输至网络侧,进一步提高用户体验。
终端设备进行数据业务所需发送的数据包的数量可能相对较多,进行语音业务所需发送的数据包的数据量相对较少。因此,在一种可能的实施方式中,终端设备还可以通过分时占用第二射频发送通路TX,向第一LTE网络发送相关于终端设备所进行数据业务的一个或多个业务数据包。如此,使得终端设备能够快速的将大量相关于数据业务的业务数据包快速传输至网络侧,进一步提高用户体验。
可以理解的,由于第一LTE网络和5G网络非独立组网,终端设备进行数据业务的过程中,传输至第一LTE网络的业务数据以及传输至5G网络的业务数据,可以到达相同的核心网,进而被转发到相应的网络或设备。
示例性的,当5G网络和第一LTE网络(为了方便描述,在以下各个示例中将其称为一个4G网络)非独立组网时,终端设备在未进行相关于第一SIM卡(为了方便描述,在以下各个示例中将其称为卡1)或第二SIM卡(为了方便描述,在以下各个示例中将其称为卡2)的语音通话时,终端设备所显示的图形用户界面(GUI,graphical user inter face)的信号状态栏,可以向用户显示终端设备在当前时刻的网络状态。示例性,如图13A1或图13A2所示,图形用户界面(GUI,graphical user inter face)右上角位置的信号状态栏,可以提示用户该终端设备10已经通过卡1同时连接到了5G网络和一个4G网络中,且终端设备10通过卡2连接到了另一个4G网络。
需要说明的是,在终端设备通过卡1同时连接到4G网络和5G网络时,如果终端设备被配置为优先通过5G网络进行数据业务,则终端设备在未进行语音业务的过程中,通常采用图13A所示图形用户界面中网络状态栏所显示的图样及字样,来表示终端设备10已经通过卡1同时连接到了5G网络和一个4G网络中,且终端 设备10通过卡2连接到了另一个4G网络。当且仅当终端设备在进行相关于卡1的语音通话的过程中,才通过图13B所示图形用户界面中网络状态栏所显示的图样及字样,来指示用户所进行的相关于卡1的语音通话,为通过4G网络进行的、相关于卡1的语音通话。
示例性的,该终端设备10可在用户的操作下,通过卡1在5G网络下进行数据业务,通过卡1在其连接的一个4G网络下与其他用户所持有的终端设备进行基于VOLTE的语音通话。示例性的,该终端设备10与用户B持有的终端设备B进行语音通话时,终端设备10可显示如图13B所示的图形用户界面。该图形用户界面可显示终端设备10的来电信息及通话状态;比如,显示进行中的语音通话所使用的SIM卡为卡1、该语音通话的对象为用户B以及该用户对象B所使用的电话号码、该语音通话的持续时间等;该图形用户界面中还可以显示用于接收用户的操作以管理该语音通话的一个或功能图标,具体如显示挂断图标131、静音图标132、拨号键盘图标133、通讯录图标134、添加通话图标135以及扬声器图标136。终端设备响应于用户对前述各个图标的触发所对应进行的处理流程可参考现有技术,此处不再赘述。
终端设备10使用卡1进行语音通话时,并不会断开其与5G网络之间的连接,如图13C所示的图形用户界面提示用户该终端设备10仍然与5G网络保持连接。相应的,在使用卡1进行语音通话的过程中,终端设备10仍然可以使用5G网络进行数据业务;比如,在使用卡1进行语音通信的过程中,终端设备通过5G网络自动下载并更新用于更新一个或多个应用程序的数据包、自动同步终端设备中存储的个人数据至云平台等。
如前所述,如果用户触发挂断图标131挂断了其正在进行的相关于卡1的语音通话,则终端设备所显示图形用户界面中的网络状态栏,可能显示如图13A所示图形用户界面中网络状态栏所显示的图样即字样。
接着,结合前述各个实施例可知,终端设备使用卡1进行语音通信的过程中,可以接收到来自另一个用户(比如用户C)的来电;此时,终端设备可通过相应的图形用户界面来显示用户C的来电信息。示例性,终端设备10可显示如图13C所示的图形用户界面;用户可在如图13C所示的界面中,触发挂断并接听图标137,以挂断正在进行的、相关于卡1的语音通话并接听卡2来电;用户可在如图13C所示的界面中,触发继续并挂断图标138,挂断使得终端设备10挂断相关于卡2的来电并继续进行相关于卡1的语音通话。
基于与前述各个方法实施例相同的构思,本申请实施例中还提供了一种终端设备10,如图14所示,所述终端设备10包括处理器101和收发器102,所述收发器102包括第一射频接收通路RX1、第二射频接收通路RX2、第二射频发射通路TX、第一射频发送通路TXn和第三射频接收通路RXn;所述终端设备10还包括第一SIM卡接口103和第二SIM卡接口104,所述第一SIM卡接口103用于与第一SIM卡通信,所述第二SIM卡接口104用于与第二SIM卡通信;所述终端设备10通过所述第一SIM卡连接到5G网络和第一长期演进LTE网络,所述终端设 备10还包括处理器101,所述处理器101至少用于执行:
