呼叫控制方法、服务器、车载终端及移动终端、存储介质
相关申请的交叉引用
本申请基于申请号为201611260074.4、申请日为2016年12月30日的中国专利申请提出,并要求该中国专利申请的优先权,该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本发明涉及移动通信领域,尤其涉及一种呼叫控制方法、服务器、车载终端及移动终端、存储介质。
背景技术
随着家用汽车的普及,汽车电子技术也随之发展起来,通过应用定位技术和移动通信技术,汽车后视镜可以提供导航、行车记录、娱乐等功能。
交通法规明确规定驾驶员在开车过程中禁止用手机通话,为此,人们在行车过程中通常使用免提进行通话,这样既可以满足行车中的通话需求,还可以避免手动操控手机不得不单手驾车,从而避免交通隐患。
在一种方案中,有通过蓝牙(或其他近距离传输技术)将手机来电转移到汽车电子设备上,然后自动接听电话的功能。这种方案需要手机充当网关功能,通话质量受到车内短距离通信技术的影响还增加手机的耗电量,该种方案的另一个弊端是必须将手机的通话功能加以改进,使之能够将电话转移到车载终端上去。而这种技术改进需要对基础的通话功能进行改进,一般需要手机出厂之前预装,而不能通过出厂后第三方软件解决。
在另一种方案中,用户可以通过设置呼叫转移将智能手机来电转移到车载终端。但这种方案的不足之处在于用户需要在行车前设置呼叫转移, 行车结束后再取消呼叫转移,对用户来说,使用起来非常不方便。另外,目前呼叫转移技术前提是手机和车载终端使用不同的电话号码,而实际中,由于行车时间的不确定性,通过车载终端对应的电话号码联系用户并不合理。

具体实施方式
为了能够更加详尽地了解本发明实施例的特点与技术内容,下面结合附图对本发明实施例的实现进行详细阐述,所附附图仅供参考说明之用,并非用来限定本发明实施例。
本发明实施例涉及到语音服务系统、车载终端和移动终端。其中,语音服务系统包括:语音支撑系统、语音业务服务器。其中,语音支撑系统具有两种类型,分别为:移动网络的语音业务核心网、互联网语音业务系统。进一步,移动网络的语音业务核心网为:IP多媒体子系统(IMS,IP Multimedia Subsystem)核心网或第五代(5G,5th Generation)语音业务核心网。
参照图1,语音服务系统适用于基于移动网络的IMS核心网的语音业务,图1以长期演进(LTE,Long Term Evolution)移动网络提供的语音业务为例,图1所示的业务网络图同样适合于未来5G移动网络(未来5G语音业务核心网可以看作是EPC和IMS的演进版),如图2所示,语音服务系统包括:语音业务服务器、IMS核心网/5G语音业务核心网。
参照图3,语音服务系统适用于基于移动网络分组域的OTT(Over The Top,一般指互联网业务)语音支撑系统,基于此,语音服务系统包括:语音业务服务器、OTT语音支撑系统。
综合以上两种情形,本发明实施例的语音服务系统包括:语音业务服务器和语音支撑系统,如图4所示。对于移动网络情形,语音支撑系统为移动网络语音业务核心网,可以是IMS核心网或类IMS核心网系统(如5G语音业务核心网)。对于OTT语音支撑系统,语音支撑系统提供语音业务基本呼叫控制和用户注册信息管理等功能,实际中也可以将语音支撑系统和语音业务服务器合并。此外,移动终端为手机或其他个人便携移动通信设备;车载终端是带有移动通信模块的后视镜终端或其他车载通信终端。
本发明实施例中,语音服务系统以及移动终端和后视镜终端支持以下一个或多个标识或者支持具有和以下标识同等含义的标识概念:
公有用户标识(PUI,Public User Identity):是可以公开的,是需要告诉别人的。每一个用户都有一个或多个公有的用户标识,是和其他用户进行通信时使用的身份标识,用于呼叫的寻址和路由。
私有用户标识(PVI,Private User Identity):是用户本身的,是不需要公开的,仅仅标识了用户的签约,用户也是无需感知的。本发明对应的背景移动网络每一个用户都有一个私有的用户身份,用于用户接入移动网络的注册、鉴权、认证和计费,私有用户标识不用于呼叫的寻址和路由。
联系地址(Contact):是指用户终端的IP地址,为了区分同一终端注册的不同应用实例,Contact地址附加应用实例的Instance-ID将呼叫路由到不同的应用。
全球可路由用户代理资源标识符(GRUU,Globally Routable User Agent URIs):是移动网络为解决端到端寻址问题,通过GRUU使得用户不同的设备之间有所区分,并且还能通过这种方法被路由到。GRUU可以为公有GRUU和永久性GRUU。临时性GRUU在终端注册时生效,注消系统时失效。
本发明实施例中,语音业务服务器也称为应用服务器(AS,Application Service),AS是移动网络中位于最上层的应用层设备,实现各种网络业务的触发和执行。AS与核心网之间通过标准协议SIP通信。
本发明实施例的技术方案支持以下几种情况:
1)用户的移动终端和后视镜终端采用不同的PUI。
2)用户的移动终端和后视镜终端采用相同的PUI。
3)对于以上1)-2)PVI可以相同或不同。
4)对于以上1)-2),系统支持不采用PVI标识的情形。
5)对于以上1)-2),系统支持永久GRUU或临时GRUU的情况。
本发明实施例中,AS获得车载终端的注册信息是通过第三方注册流程获得,如图5所示,车载终端注册至语音支撑系统注册单元后,语音支撑系统注册单元将注册信息转发给AS,AS即获得当前车载终端已经注册,表明车载终端处于行车状态。或者,如图6所示,AS向语音支撑系统注册单元订阅车载终端的注册事件,车载终端注册至语音支撑系统注册单元后,语音支撑系统注册单元向AS发送订阅通知,携带车载终端的注册信息。
对于OTT语音支撑系统,通过语音业务服务器或者语音业务服务器以外的语音支撑系统中某个功能单元提供终端的注册功能,语音业务服务器从注册单元获得车载终端的注册信息,语音业务服务器获得车载终端的注册信息也即获得了车载终端处于行车状态。此外,AS除了获得车载终端的注册信息外,还可以同时获得车载终端的Contact地址、GRUU等路由信息。
综合以上两种情况,AS获得车载终端的出行状态,一种方案是语音支撑系统将注册消息转发给AS。另一种方案是AS向语音支撑系统的注册单元订阅车载终端的注册事件,车载终端注册至语音支撑系统的注册单元后,便发送订阅通知给AS,携带注册信息。
本发明实施例中,同一个用户的一个终端获取另一个终端的信息(如GRUU、Contact地址、当前会话标识),具体方案是通过订阅注册事件获得。参照图7,图7为一个终端订阅另一个终端的GRUU和Contact信息,具体地,UE_1向语音支撑系统注册单元订阅UE_2的注册事件,当UE_2注册至语音支撑系统注册单元后,语音支撑系统注册单元向UE_1发送注册消息,携带UE_2的GRUU和Contact信息。参照图8,图8为一个终端订阅另一个终端的会话(Dialog)信息,具体地,UE_1向语音支撑系统注册单元订阅UE_2的有效会话,语音支撑系统注册单元向AS订阅UE_2的有效会话,在UE_2于UE_B建立会话Dialog_1后,语音支撑系统注册单元向 UE_1发送订阅通知,携带Dialog_1的标识。
上述方案中,UE_1可以是移动终端,UE_2可以是车载终端,UE_B为远端设备。另一种情况,UE_1可以是车载终端,UE_2可以是移动终端,UE_B为远端设备。

下面结合具体应用场景对本发明实施例的技术方案做进一步详细描述。以下各应用示例中,语音支撑系统内部各功能网元之间以及语音支撑系统和AS之间采用会话初始协议(SIP,Session Initiation Protocol)实现,其中,AS代表语音业务服务器。
应用场景一:
用户移动终端UE_A1(PUI1)和后视镜终端UE_A2(PUI2)采用不同的 PUI,一般情况,移动终端PUI1归属AS1,后视镜终端PU2归属AS2。如图19所示,呼叫控制流程包括以下步骤:
1)AS1将呼叫转发到AS2。
当某个用户拨打汽车驾驶员的移动终端PUI1时,PUI1归属AS1接收到PUI1呼叫信息(INVITE消息),AS1根据号码关联关系,即PUI1和PUI2预先建立关联(PUI1和PUI2捆绑在一个用户身份下)关系,呼叫PUI2。
本步骤是一般情况,实际中PUI1和PUI2可以归属在同一个服务器AS。
本步骤中,AS1可以向UE_A1回复100Trying消息,Trying消息由语音支撑系统路由到UE_A1。
2)AS2接收到来自AS1的呼叫信令后,根据获得当前后视镜终端行车状态呼叫PUI2。
本步骤中,AS2可以向AS1回复100Trying消息,Trying消息由语音支撑系统路由到AS1。
本步骤中,AS2为PUI2的归属业务服务器。如果用户打开汽车后视镜终端,后视镜终端(内嵌移动通信模块)会注册到语音服务系统,即通过PUI2注册。AS2获得PUI2的注册状态,也即获得了当前后视镜行车状态。如果后视镜终端处在出行状态,则对PUI2发出呼叫请求。如果行车结束,那么车载系统会关闭,后视镜终端会从系统注销,则AS2可获知汽车状态是未出行状态,即PUI2不可达,从而对PUI1的呼叫不会并发到后视镜PUI2上。
本步骤中,如果判断是行车状态,则以上两个步骤产生两路呼叫信令,分别呼移动终端和后视镜终端。
以上两个步骤,用户的两个PUI,即移动终端PUI1和后视镜终端PUI2分别归属不同的AS,是一般情况,实际部署中,一个用户相互关联的PUI1和PUI2可以归属在同一个AS中。
3)后视镜终端根据语音控制完成来电接听,或者自动启动来电接听。
对于语音控制完成来电接听功能,后视镜终端包括麦克、语音指令识别模块,可以识别“接听电话”等语音控制指令。
对于自动接听功能,后视镜终端接收到来电信令后,自动启动免提接听来电。
本步骤中,后视镜向AS2回复200OK消息。200OK最终经过语音支撑系统路由到移动终端。
以上技术方案,由于用户的两个终端使用不同的PUI注册,假定只有后视镜一个终端使用PUI2,那么无需后视镜Contact地址或者GRUU信息信令语音支撑系统便可路由到相应后视镜终端。
应用场景二:
用户的移动终端和后视镜终端采用相同的PUI,因为用户是从不同的两个终端即移动终端和后视镜终端注册到语音服务系统,则两个终端的Contact地址不同,设移动终端为Contact1,后视镜终端为Contact2。如图20所示,呼叫切换流程包括以下步骤:
1)当移动终端PUI来电时,PUI归属AS接收到呼叫信息(INVITE消息),分别向两个终端发出两路呼叫Contact1和Contact2。
本步骤中,如果后视镜终端处于行车状态,则AS会从注册服务网元获得用户PUI的两个联系地址Contact1和Contact2,AS呼叫PUI的信令经过语音支撑系统,语音支撑系统将呼叫根据Contact联系地址分别路由到移动终端和后视镜终端。
本步骤中,可以由AS发出两路呼叫(PUI+Contact1和PUI+Contact2),也可以AS发出一路呼叫(PUI),而由语音支撑系统(移动网络为IMS核心网)并发两路呼叫(PUI+Contact1和PUI+Contact2)分别抵达移动终端和后视镜终端。
这里,移动终端和后视镜终端接收到INVITE消息后,可以向AS发送振铃消息180Ringing,AS接收到两路180Ringing后向主叫方发送Ringing消息。
如果后视镜终端处于未出行状态,则AS服务器(或语音支撑系统)只获得PUI用户的一个联系地址,并不会将呼叫并发到后视镜上。
如果用户的移动终端处于关机,而后视镜终端已经注册系统,那么此时AS(语音支撑系统)也只获得该PUI用户的后视镜终端地址,只呼叫后视镜终端。
2)根据语音控制来电接听,或者后视镜来电后自动启动接听。
对于支持PVI的语音服务系统,本方案适用于移动终端和后视镜的PUI和PVI都相同的情况,或者适用于PUI相同但PVI不相同的情况,AS将发出两路终呼信令,分别抵达移动终端和汽车后视镜。
这里,后视镜接听来电后,返回200OK消息,200OK消息经过AS和语音支撑系统最终路由到主叫方终端。主叫方终端接收到200OK消息后,向对端返回确认消息ACK。
技术方案2适用于语音服务系统不支持GRUU的情况,此时如果PUI用户拥有超过移动终端和后视镜终端的情况,由于IP地址的临时性,可以在注册时附加本Contact地址为车载终端的信息,AS根据附加信息能够精准判断哪个联系地址是后视镜终端,从而精准将呼叫指定到后视镜终端。如果不采用附加信息,那么所有的使用PUI注册语音服务系统的终端(包括后视镜终端)都会被语音服务系统呼叫。
应用场景三:
用户移动终端和后视镜终端采用相同的PUI,假定移动终端全球可路由唯一标识为GRUU1,后视镜终端的全球唯一标识为GRUU2。如图21所示,呼叫切换流程包括以下步骤:
1)AS接收到呼叫PUI信令后,呼叫移动终端GRUU1,根据后视镜的行车状态,呼叫后视镜终端GRUU2。
具体地,AS接收到呼叫PUI的INVITE消息后,向移动终端GRUU1发送INVITE消息,根据后视镜的行车状态,向后视镜终端GRUU2发送INVITE消息。
本步骤中,当某个主叫方用户呼叫驾驶员PUI时,即发送INVITE消息,PUI归属AS接收到PUI呼叫INVITE消息。如果移动终端用户打开汽车后视镜终端,后视镜终端(内嵌移动通信模块)注册到语音服务系统,AS获得后视镜的注册状态,也即获得了后视镜当前行车状态。如果后视镜终端处在出行状态,则对PUI+GRUU2发出呼叫请求INVITE消息。如果处于未出行状态,那么后视镜终端不会注册到语音服务系统,则AS可获知汽车状态是未出行状态,从而对移动终端的呼叫不会同步到后视镜GRUU2上。
2)后视镜终端根据语音控制完成来电接听,或者自动启动来电接听。
对于语音控制完成来电接听功能,后视镜终端包括麦克、语音指令识别模块,可以识别“接听电话”等语音控制指令。具体地,后视镜终端接收到INVITE后,对于语音控制完成来电接听功能,可以先振铃返回180Ringing消息,后视镜终端包括麦克、语音指令识别模块,可以识别“接听电话”等语音控制指令,后视镜在完成接听后返回200OK消息。
对于自动接听功能,后视镜终端接收到来电信令后,自动启动免提接听来电。具体地,后视镜终端接收到INVITE后,对于自动接听功能,后视镜终端接收到来电信令后,自动启动免提接听来电,并直接返回200OK消息。
应用场景四:
移动终端振铃后,后视镜将呼叫拉到本终端。移动终端和后视镜终端 以及语音服务系统都支持GRUU,本方案用户移动终端和后视镜采用相同的PUI,假定移动终端全球可路由唯一标识为GRUU1,后视镜终端的全球唯一标识为GRUU2。假定主叫方PUI_A归属AS_A,PUI归属AS_B。如图22所示,呼叫切换流程包括以下步骤:
1)语音控制后视镜启动语音呼叫转移。
本步骤中,当移动终端振铃后,即语音服务系统呼叫移动终端PUI+GRUU1,(驾驶员)通过语音控制后视镜终端启动将语音呼叫切换到后视镜(PUI+GRUU2)的请求信令。
2)后视镜发出呼叫转移信令。
本步骤中,后视镜在接收到语音指令后,向语音服务系统发出呼叫转移请求(转移到PUI+GRUU2)。具体步骤是,后视镜接听到“语音转移”或同等含义的语音指令后进行识别,之后向语音服务系统发出呼叫转移请求INVITE STN(STN:Session Transfer Number),本方案呼叫转移请求发生在移动终端振铃但接听,即尚未建立媒体面之时。
后视镜终端可以通过图8所描述的方案获得移动终端的当前会话Dialog,即后视镜订阅SUBSCRIBE PUI的Dialog事件,在移动终端振铃时,即建立早会话Dialog,此时AS_B向后视镜终端发送订阅通知消息NOTIY,携带该会话标识。
在发出呼叫转移请求时STN的参数为该Dialog,转移请求还可以携带GRUU2信息指明将会话Dialog转移到GRUU2。
3)后视镜终端获得转移后的语音呼叫,自动接听或者振铃后语音控制接听。
对于自动接听功能,后视镜终端接收到来电信令后,自动启动免提接听来电。
对于语音控制完成来电接听功能,后视镜终端包括麦克、语音指令识 别模块,可以识别“接听电话”等语音控制指令。
应用场景五:
移动终端振铃后,后视镜将呼叫拉到本终端。本方案基于联系地址方案,呼叫转移请求发生在移动终端振铃但接听时,即尚未建立媒体面之时。本方案用户移动终端和后视镜采用相同的PUI,假定移动终端注册后的联系地址为Contact1,后视镜终端注册后的联系地址为Contact2,假定PUI归属AS。包括以下步骤:
1)语音控制后视镜启动语音呼叫转移。
本步骤中,当移动终端振铃后,即语音服务系统呼叫移动终端PUI+Contact1,(驾驶员)通过语音控制后视镜启动将语音呼叫切换到后视镜(PUI+Contact2)的请求信令。
2)后视镜发出呼叫转移信令。
本步骤中,后视镜在接收到语音指令后,向语音服务系统发出呼叫转移请求(转移到PUI+Contact2)。具体步骤是,后视镜接听到“语音转移”或同等含义的语音指令后进行识别,之后向语音服务系统发出呼叫转移请求并携带Contact2。本方案呼叫转移请求发生在移动终端振铃但接听时,即尚未建立媒体面之时。
本步骤中,后视镜终端可以通过图15所描述的方案获得移动终端的当前会话Dialog,在发出呼叫转移请求时携带该Dialog,转移请求还可以携带Contact2地址信息指明将会话Dialog转移到Contact2地址。
3)后视镜终端获得转移后的语音呼叫,自动接听或者振铃后语音控制接听。
对于自动接听功能,后视镜终端接收到来电信令后,自动启动免提接听来电。
对于语音控制完成来电接听功能,后视镜终端包括麦克、语音指令识 别模块,可以识别“接听电话”等语音控制指令。
上述方案中,后视镜终端振铃或接听后,AS可以取消对原来移动终端的呼叫请求。
上述方案中,可以将图22中的GRUU替换为Contact,即可实现本场景的流程。
应用场景六:

本步骤中,后视镜在接收到语音指令后,向语音服务系统发出呼叫转移请求(转移到PUI+GRUU2)。具体步骤是,后视镜接听到“语音转移”或同等含义的语音指令后进行识别,之后向语音服务系统发出呼叫转移请求并携带GRUU2。本方案呼叫转移请求发生在移动终端已经与其他用户正在进行通话,即完成媒体面链路的建立之后。
本步骤中,后视镜终端可以通过图8所描述的方案获得移动终端的当前会话Dialog,在发出呼叫转移请求时携带该Dialog,转移请求还可以携带GRUU2信息指明将会话Dialog转移到GRUU2。
3)后视镜终端建立媒体链路,自动接听通话。
