Description

一种终端设备呼叫冲突的处理方法和终端设备 技术领域
本发明涉及无线通信技术领域，尤其涉及一种终端设备呼叫冲突的处理方法和终端设备。
背景技术
目前，智能手机的硬件体系结构大多采用的是双处理器架构，其中，应用处理器运行操作系统，负责整个操作系统的控制，包括音视频处理、文档处理、数据处理等手机附加应用功能；基带处理器负责通信协议的处理，实现手机的基本通信功能。采用双处理器的架构，能够丰富、扩展手机的功能，却也使得手机内部的处理更加复杂。
用户在使用手机通话中，存在这样的场景：用户在进行去电的同时，恰好接收到来电。在传统单卡单通的手机中，不会存在冲突。这是因为，对于单卡手机，在这样的场景下，进行来电或去电是依靠抢占协议栈的先后顺序来确定的。如果去电优先占据协议栈，会根据手机是否设置来电等待处理来电信息；如果来电优先占据协议栈，则去电失败。
但是在双处理器架构的智能手机中，去电信息需要先经过应用处理器，然后到达基带处理器并完成去电操作，来电信息需要先经过基带处理器，然后到达应用处理器才能提示用户来电呼入。如果用户的去电正在应用处理器进行处理，同时来电已经到达基带处理器，就会发生冲突，导致手机处理混乱，反之亦然。
对于双卡单通手机，对于不同卡(不同账号)的来电和去电的冲突，目前尚无任何机制。因为每个账号对应各自独立的一个协议栈，一旦发生来电 和去电同时到达的情况，来电和去电会分别更新各自所属的协议栈，此时会造成去电停留在电话呼叫界面，但是无法拨打出去，而呼叫该手机的主叫方听到对方有响铃，但是被叫方没有任何来电显示，也就是说，来电和去电都无法进行下去。因此，对于双卡单通手机的来电去电冲突，尚缺乏一种有效的保护机制。

具体实施方式
为了使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明作进一步地详细描述，显然，所描述的实施例仅仅是本发明一部份实施例，而不是全部的实施例。基于本发明中的实施例，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它实施例，都属于本发明保护的范围。
下面以图1为例详细说明本发明提供的终端设备呼叫冲突的处理方法。本实施例主要以第一终端设备接收呼入的场景为例进行说明，第一终端设备包括基带处理器、无线支持装置和应用处理器，所述无线支持装置包括有状态机。基带处理器相当于一个协议处理器，负责数据处理与储存，主要组件为数字信号处理器(DSP)、微控制器(MCU)、内存(SRAM、Flash)等单元，主要功能为基带编码/译码、声音编码及语音编码等。应用处理器为终端设备的多媒体应用处理模块，其功能为运行操作系统和各种应用程序。无线支持装置为应用处理器和基带处理器之间的通信桥梁。通过状态机可以记录第一终端设备的账号是否处于来电、去电或者空闲状态。
该方法包括如下步骤：
步骤100，第一终端设备的基带处理器接收网络发送的来自第二终端设备的呼入请求消息；所述呼入请求消息携带所述第一终端设备的第一账号的信息；
具体的，第一终端设备可以是具有应用处理器和基带处理器的智能手机，例如具有双卡单通功能的智能手机，其中，双卡分别对应用户的第一账号和第二账号。第一账号和第二账号可以分别是两个客户识别模块(Subscriber Identity Module，SIM)卡。第二终端设备可以是具有通话功能的手机或座机等。
当第二终端设备的用户需要与第一终端设备的用户进行通话时，通过在第二用户设备上输入第一账号(当然也可以是第二账号)的信息，发起对第一用户设备的呼入请求消息。
这个呼入请求消息会首先发送至网络，然后再由网络转送到第一终端设备的基带处理器进行接收。
步骤110，所述基带处理器根据所述呼入请求消息向所述第一终端设备的无线支持装置发送来电指示消息；
具体的，基带处理器接收到来自第二用户设备的呼入请求消息时，生成来电指示消息并发送给第一终端设备内的无线支持装置。所述来电指示消息包括所述第一账号的信息。在本发明中，无线支持装置是指无线接口层(Radio Interface Layer，RIL)。
RIL工作在点对点协议(Point to Point Protocol,PPP)、传输控制协议/因特网互联协议(Transmission Control Protocol/Internet Protocol,TCP/IP协议)之下，负责数据的可靠传输、AT(Attention)命令(一种调制解调器命令语言)的发送以及响应的解析。当然，除了对网络的支持，RIL也支持短消息服务、语音通话等功能。
换句话说，RIL能够为应用处理器中运行的应用程序提供无线通信相关的服务，包括呼叫控制、短消息、通用无线分组业务(General Packet Radio  Service,GPRS)等功能。而且对于上层应用程序来说，可以抽象地把RIL看作逻辑设备，只需要和RIL通信就能够获得所需要的服务。
步骤120，所述无线支持装置获取所述第一终端设备的状态；
具体的，无线支持装置包括状态机，因此可以通过状态机来记录第一终端设备的第一账号或第二账号是否处于来电、去电或者空闲状态。状态机根据不同的触发条件记录终端设备的状态，处理器则根据状态机的不同状态执行不同的处理。
当无线支持装置接收到呼入请求消息的时候，会先对第一终端设备的状态进行检测，确定第一账号、第二账号是否已经处于来电或者去电的状态。
如果第一终端设备的第一账号或者第二账号已经处于来电或者去电的状态，则执行步骤130；如果第一终端设备的第一账号和第二账号都处于空闲状态，则执行下述步骤140。
步骤130，当所述第一终端设备的的状态为来电状态或者去电状态时，无线支持装置向基带处理器发送拒绝状态更改消息，用于基带处理器根据拒绝状态更改消息向网络发送拒绝第二终端设备呼入的响应信息。
具体的，在实际应用中，对于第一账号和第二账号，状态机对来电或者去电状态可以分别进行记录，例如，可以将第一账号的去电状态记录为sub0/MO call，将第一账号的来电状态记录为sub0/MT call，将第二账号的去电状态记录为sub1/MO call，将第二账号的来电状态记录为sub1/MT call。
步骤140，当所述第一终端设备的的状态为空闲状态时，所述无线支持装置根据所述来电指示消息将所述第一终端设备的的状态更新为来电状态，并占据互斥锁；
具体的，在确定状态机为空闲状态时，RIL根据对第一账号的呼入请求消息，对第一终端设备的的状态更新为来电状态。
本发明中，第一终端设备的在来电状态或去电状态的时候，采用互斥锁来来防止在当前的来电状态或去电状态下再发生其他呼入或者呼出占用通信 资源(此处不包括允许来电等待)的情况。
因此，在RIL对状态机的状态进行更新，例如更新为来电状态时，RIL还生成第一校验码，并将第一校验码发送给状态机；其中，第一校验码包括：第一账号的信息和第二终端设备的信息。
步骤150，所述无线支持装置向所述基带处理器发送状态更改成功消息；
具体的，在对第一终端设备的的状态进行更新后，RIL向基带处理器发送状态更改成功消息。
步骤160，所述基带处理器根据所述状态更改成功消息，将所述呼入请求消息发送给第一终端设备的应用处理器，用以所述应用处理器根据所述呼入请求消息向用户提示来电信息。
具体的，基带处理器接收到状态更改成功消息后，将来自第二终端设备的呼入请求消息发送给应用处理器。
应用处理器在接收到呼入请求消息之后，向用户提示有来自第二终端设备的来电信息。
如果用户根据提示选择接听来电，则通过网络建立第一终端设备和第二终端设备之间的语音通路。
如果用户根据提示拒绝接听来电，或者在建立语音通路后，第一终端设备或第二终端设备任意一方的用户挂断通话时，所述方法还包括：
步骤170，当所述应用处理器接收到用于结束与第二终端设备之间通话的挂断指令时，向所述无线支持装置发送通话结束消息；
具体的，应用处理器接收到的挂断指令可以是作为被叫方的第一终端设备的用户输入的拒绝接听的指令，也可以是该用户在通话建立之后的任意时间输入的挂断通话的指令；还可以是来自基带处理器转发的挂断指令，而基带处理器的挂断指令可以是由网络发送的第二终端设备接收到其用户输入的挂断通话的指令信息。
无论从哪里接收到挂断指令，都会根据该指令生成通话结束消息发送到 RIL。
步骤180，所述无线支持装置根据所述通话结束消息生成来电状态释放消息，并解除所述互斥锁；
具体的，RIL在接收到通话结束消息时，生成来电状态释放消息用以释放被状态机记录和锁定的来电状态。
步骤190，所述第一终端设备根据所述来电状态释放消息和所述第一校验码，将状态复位为空闲状态；
具体的，根据RIL的来电状态释放消息，以及第一校验码，将状态机进行复位。
在复位的过程中，首先会将状态机记录的状态更新为结束通话的状态，等待该通话连接占用的内存释放完毕，第一终端设备内相关参数都复位完成后，再将状态机记录的状态更新为空闲状态，并将第一校验码设置为无效。比如，具体可以是将第一校验码复位为0。
在上述过程中，还可能包括其他一些情况：
例如，在上述步骤140在所述无线支持装置根据来电指示消息将所述第一终端设备的状态更新为来电状态，并占据互斥锁之后(此时来电指示消息还未发送到应用处理器，或者还未完成语音通路的建立)，应用处理器接收到第一终端设备的用户输入的呼出指令，则：
应用处理器根据呼出指令向RIL发送呼出请求消息；
RIL根据呼出请求消息对第一终端设备的状态进行检测；
当RIL检测到第一终端设备已经处于来电状态时，向应用处理器发送拒绝呼出响应信息。
此外，应用处理器还会释放该呼出请求消息占用的内存以及相关参数。
又如，在步骤110基带处理器将所述来电指示消息发送给所述第一终端设备的无线支持装置的同时，应用处理器也将呼出请求消息发送给无线支持装置，则：
无线支持装置获取预先存储的呼入呼出优先级的配置信息；该配置信息用于规定当呼入、呼出同时到达RIL时，选择呼入或呼出优先处理的规则；
无线支持装置根据配置信息选择将第一终端设备的状态更新为来电状态或者更新为去电状态。
本发明实施例一，以第一终端设备接收到第二终端设备的呼入请求消息场景为例，对本发明呼叫冲突的处理方法进行了说明。
当第一终端设备接收到呼入请求消息时，首先确认其内部的状态机记录的第一终端设备当前所处状态是否为空闲状态；当处于空闲状态时，根据呼入请求消息将第一终端设备的状态更新为来电状态，并通过互斥锁对该来电状态进行保护；如果第一终端设备当前的状态不是空闲状态，则拒绝该呼入请求。本发明实施例提供了一种稳定、可靠的呼叫冲突的处理方法，能够在来、去电发生冲突的情况下有效的保证来电或者去电中的一个进程能够顺利进行，提高用户体验。
下面以图2为例详细说明本发明提供的呼叫冲突的处理方法。本实施例主要以第一终端设备作为主叫呼出的场景为例进行说明，该方法包括如下步骤：
步骤200，第一终端设备的应用处理器接收用户输入的呼出指令；
具体的,在第一终端设备进行呼出时,首先要接到用户输入的呼出指令。该呼出指令通过第一终端设备的输入设备接收下来，并传送至应用处理器。
其中，输入设备可以包括第一终端设备的触摸屏、键盘、麦克风等等。
步骤210，所述应用处理器根据所述呼出指令向所述第一终端设备的无线支持装置发送呼出请求消息；
具体的，应用处理器在接收到呼出指令时，根据呼出指令生成呼出请求消息发送到第一终端设备内的无线支持装置。其中呼出请求消息携带所述第一终端设备的第一账号的信息和第二终端设备的信息。
与上述实施例相同，无线支持装置是指RIL。
步骤220，所述无线支持装置获取所述第一终端设备的状态；
具体的，无线支持装置包括状态机，通过状态机来记录第一终端设备的第一账号或第二账号是否处于来电、去电或者空闲状态。需要说明的是，在第一终端设备已经处于发起去电的状态或者已经处于去电的状态时，用户是无法通过第一终端设备再发出其他去电请求的，也就是说，当第一终端设备接收用户输入的呼出指令的时候，在正常情况下，状态机所记录的第一终端设备的状态是不可能处于去电状态的，因此通常情况无需对第一终端设备是否处于去电状态进行讨论。但是并不能排除状态机发生异常的情况，会存在第一终端设备处于去电状态的可能性。接下来，我们主要对来电和空闲状态进行讨论。
当无线支持装置接收到呼出请求消息的时候，会先确认第一终端设备的状态，从而确定第一账号、第二账号是否已经处于来电的状态。
如果第一终端设备的第一账号或第二账号已经处于来电状态，则执行步骤230；如果第一终端设备的第一账号或者第二账号都处于空闲状态，则执行下述步骤240。
步骤230，当所述第一终端设备的状态为来电状态时，无线支持装置向应用处理器发送拒绝状态更改消息，用于应用处理器根据拒绝状态更改消息拒绝对第二终端设备的呼出请求消息，并且提示用户来电信息。
具体的，提示用户来电信息及来电处理的过程，均依照上述实施例中来电场景的描述，此处不再赘述。
步骤240，当检测所述第一终端设备为空闲状态时，所述无线支持装置根据所述呼出请求消息将所述第一终端设备的状态更新为去电状态，并占据互斥锁；
具体的，在确定第一终端设备为空闲状态时，RIL根据通过第一账号向第二终端设备的呼出请求消息，对第一终端设备的状态进行更新，更新为去电状态。
本发明中，通过状态机记录第一终端设备在来电状态或去电状态的时候，采用互斥锁来来防止在当前的来电状态或去电状态下再发生其他呼入或者呼出占用通信资源的情况。对于去电状态下允许呼叫等待时呼入的处理，后续会有单独说明。
因此，在RIL对状态机进行更新，例如更新为第一终端设备处于去电状态时，RIL还会生成第二校验码；其中，第二校验码包括：第一账号的信息和第二终端设备的信息。
步骤250，无线支持装置向所述应用处理器发送状态更改成功消息；
具体的，在对第一终端设备的状态进行更新后，RIL向应用处理器发送状态更改成功消息。
步骤260，应用处理器根据所述状态更改成功消息，将所述呼出请求消息发送给第一终端设备的基带处理器，用以所述基带处理器根据所述呼出请求消息向网络发送对所述第二终端设备的呼叫请求。
具体的，应用处理器接收到状态更改成功消息后，将呼出请求消息发送给基带处理器，并通过基带处理器发送到网络，通过网络建立第一终端设备和第二终端设备之间的语音通路。
如果第二终端设备的用户拒绝呼入请求消息，或者在建立语音通路后，第一终端设备或第二终端设备任意一方的用户挂断通话时，所述方法还包括：
步骤270，当所述应用处理器接收到用于结束与第二终端设备之间通话的挂断指令时，应用处理器向所述无线支持装置发送通话结束消息；
具体的，应用处理器接收到的挂断指令可以是作为被叫方的第一终端设备的用户输入的拒绝接听的指令，也可以是该用户在通话建立之后的任意时间输入的挂断通话的指令；还可以是基带处理器转发的挂断指令，基带处理器的挂断指令可以来自由网络发送的第二终端设备接收到其用户输入的挂断通话的指令信息。
无论从哪里接收到挂断指令，都会根据该指令生成通话结束消息，发送 到RIL。
步骤280，所述无线支持装置根据所述通话结束消息生成去电状态释放消息，并解除所述互斥锁；
具体的，RIL在接收到通话结束消息时，生成来电状态释放消息用以释放被状态机记录和锁定的去电状态。
步骤290，所述第一终端设备根据所述去电状态释放消息和所述第二校验码，将所述第一终端设备的状态复位为空闲状态；
具体的，根据RIL的去电状态释放消息，以及第二校验码，将状态机进行复位。
在复位的过程中，首先会将状态机记录的状态更新为结束通话的状态，等待该通话连接占用的内存释放完毕，第一终端设备内相关参数都复位完成后，再将状态机记录的状态更新为空闲状态，并将第二校验码设置为无效。比如，具体可以是将第二校验码复位为0。
在上述过程中，还可能包括其他一些情况：
例如，在步骤240，无线支持装置根据所述呼出请求消息将第一终端设备的状态更新为去电状态，并占据互斥锁之后，基带处理器接收到网络发送的来自第三终端设备的呼入请求消息，此时要根据第一终端设备的应用处理器是否有来电等待的配置信息而确定对于来电的处理方案。其中，来电等待的配置信息预先由用户设置，并存储在第一终端设备中，通过应用处理器能够获取该配置信息。
具体的处理方案至少可以包括以下三种：
在第一种方案中，应用处理器中没有存储来电等待的设置信息，则处理方法如下：
基带处理器接收网络发送的来自第三终端设备的呼入请求消息，向无线支持装置发送来电指示消息；无线支持装置根据来电指示消息对第一终端设备的状态进行检测；当无线支持装置检测到第一终端设备处于去电状态时， 向应用处理器发送拒绝呼入响应信息；应用处理器将所述拒绝呼入响应信息通过基带处理器发送给网络，从而发送给第三终端设备。
在第二种方案中，应用处理器中存储有来电等待的设置信息，且呼入请求消息是对呼出所用的第一账号的，则处理方法如下：
基带处理器根据呼入请求消息生成来电指示消息发送给无线支持装置；其中来电指示消息携带有第一终端设备的第一账号的信息；无线支持装置对来电指示消息进行处理，当识别出具有与所述呼出指令相同的第一账号的信息时，将来电指示消息发送给无线支持装置；无线支持装置检测到第一终端设备处于去电状态时，将来电指示消息发送给应用处理器；应用处理器根据来电指示消息生成提示信息，用以提示用户有来自第三终端设备的来电呼入；当应用处理器接收用户输入的呼出挂起指令时，将呼出挂起指令发送给无线支持装置；无线支持装置根据呼出挂起指令将第一终端设备的状态更新为去电挂起状态，并将第一终端设备与第二终端设备之间的呼叫暂时挂起；当第一终端设备为去电挂起状态时，应用处理器接收基带处理器收到的网络发送的第三终端设备的来电信息，同时接收并发送所述用户输入的向所述第三终端设备发送的信息。
进一步的，在去电挂起状态下，当应用处理器接收用户输入的呼出恢复指令时，生成呼出恢复指令消息发送给所述无线支持装置；无线支持装置根据呼出恢复指令消息将第一终端设备的状态重新更新为去电状态；并将第一终端设备与第三终端设备之间的呼叫暂时挂起。
当应用处理器接收到用于结束与第二终端设备之间通话的挂断指令时，向无线支持装置发送通话结束消息；无线支持装置根据通话结束消息生成去电状态释放消息，并解除互斥锁；从而根据去电状态释放消息和第二校验码，将第一终端设备的状态复位为空闲状态。
因为此时来电还未结束，因此，无线支持装置随后就将第一终端设备的状态更新为来电状态，占据互斥锁，并生成第三校验码；第三校验码包括第 一账号的信息和第三终端设备的信息。随后来电呼入的处理过程在上述实施例中已经进行了详细描述，此处不再赘述。
另外，还可能存在先断开第一终端设备与第三终端设备之间的语音通路的情况。
此时，应用处理器接收到用于结束与第三终端设备之间通话的挂断指令，生成通话结束消息发送给无线支持装置。无线支持装置根据通话结束消息将第一终端设备由去电挂起状态重新更新为去电状态，从而继续连通第一终端设备与第二终端设备之间的语音通路。
在第三种方案中，应用处理器中存储有来电等待的设置信息，但呼入请求消息不是对呼出所用的第一账号的，而是对第二账号的，则处理方法如下：
基带处理器根据接收到的呼入请求消息向无线支持装置发送来电指示消息；其中来电指示消息携带有第一终端设备的第二账号的信息；无线支持装置对来电指示消息进行处理，当无法识别出具有与所述呼出指令相同的第一账号的信息时，或者识别出来电指示消息中携带有与呼出请求消息不同的账号的信息时，拒绝对第二账号呼入请求。基带处理器还会释放该呼入请求占用的内存以及相关参数。
本发明实施例二，以通过第一终端设备主动对第二终端设备进行呼叫的场景为例，对本发明呼叫冲突的处理方法进行了说明。
当第一终端设备接收用户输入的呼出请求消息时，首先确认其内部的状态机记录的第一终端设备当前所处是否为空闲；当处于空闲时，根据呼出请求消息将第一终端设备的状态更新为去电状态，并通过互斥锁对该去电状态进行保护；如果第一终端设备当前的状态不是空闲状态，则拒绝该呼出请求。如果在第一终端设备处于去电状态下再接到呼入，则根据是否设置来电等待来进行对呼入的处理。如果没有设置来电等待，或者呼入请求消息携带的账号信息与正在进行呼出的账号的信息不匹配，则直接拒绝呼入；如果设置了来电等待且呼入请求消息的账号信息与正在进行呼出的账号的信息匹配，则 可以在呼入和呼出间进行切换，在第一终端设备处于不同状态下实现与呼入的终端设备之间的语音通信或者与呼出的终端设备之间的语音通信。本发明实施例提供了一种稳定、可靠的呼叫冲突的处理机制，能够提高用户体验。
相应的，本发明实施例还提供了一种终端设备，用以实现上述实施例1所述的方法。
本实施例的终端设备可以具体为智能手机，特别是具有双卡单通功能的智能手机。也就是说，本实施例中的终端设备，包括有两个可以进行通话的账号，分别为第一账号和第二账号。为区别本发明的终端设备与其他与本发明终端设备进行通信的其他终端设备，将本发明的终端设备称为第一终端设备。如图3所示，该第一终端设备包括：基带处理器31、应用处理器32无线支持模块33。

当所述无线支持装置33检测到所述第一终端设备处于来电状态时，所述无线支持装置33还用于，向所述应用处理器32发送拒绝呼出响应信息。
另外，还有一种特殊情况是，来电和去电同时到达无线支持装置33，也就是当所述基带处理器31将所述来电指示消息发送给所述无线支持装置33的同时，所述应用处理器32还用于，将所述呼出请求消息发送给所述无线支持装置33；
所述无线支持装置33还用于，获取预先存储的呼入呼出优先级的配置信息；并根据所述配置信息选择，将所述第一终端设备的状态更新为来电状态或者更新为去电状态。

上述该装置包括的基带处理器31、应用处理器32和无线支持装置33在接收第二终端设备呼入的场景下的具体工作过程已经在前述相应的方法实施例中进行了详细描述，此处不再赘述。
本实施例提供的终端设备，在接收到呼入请求消息时，首先确认其内部的状态机记录的第一终端设备当前所处状态是否为空闲状态；当处于空闲状态时，根据呼入请求消息将第一终端设备的状态更新为来电状态，并通过互斥锁对该来电状态进行保护；如果第一终端设备当前的状态不是空闲状态，则拒绝该呼入请求消息。本发明实施例提供了一种稳定、可靠的终端设备，能够在来、去电发生冲突的情况下有效的保证来电或者去电中的一个进程能够顺利进行，提高用户体验。

本实施例的终端设备可以具体为智能手机，特别是具有双卡单通功能的智能手机。如图5所示，该装置包括：基带处理器51、应用处理器52和无线支持装置53。
基带处理器51是手机的一个重要部件，相当于一个协议处理器，负责数据处理与储存，主要组件为数字信号处理器(DSP)、微控制器(MCU)、内存(SRAM、Flash)等单元，主要功能为基带编码/译码、声音编码及语音编码等。在一种高集成度的基带处理器51中，基带处理器51可以具体为一种高度复杂系统芯片(SoC)，不仅能够支持几种通信标准，而且还能提供多媒体功能以及用于多媒体显示器、图像传感器和音频设备相关的接口。在手机等终端设备中，基带处理器与射频和其它外围芯片作为一个模块，成为GSM/GPRS modem，提供AT命令接口。
