Description

呼叫控制设备和处理用户业务的方法
本申请要求于2013年12月31日提交中国专利局、申请号为201310751780.9、发明名称为“呼叫控制设备和处理用户业务的方法”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
本发明涉及通信领域，具体地，涉及呼叫控制设备、归属用户服务器(Home Subscriber Server，HSS)、应用服务器(Application Server，AS)和处理用户业务的方法。
背景技术
第三代合作伙伴计划(the 3rd Generation Partnership Project，3GPP)提出了一种基于网际协议(Internet Protocol，IP)的下一代网络架构，即IP多媒体子系统(Multimedia Core Network Subsystem，IMS)。与传统的电路交换(Circuit Switch，CS)域相比，IMS域能够为用户提供丰富的多媒体业务。
3GPP还提出了IMS集中业务(IMS Centralized Services，ICS)网络架构。在ICS网络架构中，传统的CS域退化为IMS域的接入网，IMS域作为核心网络，统一控制用户业务，从而能够实现在2G网络、3G网络或长期演进(Long Term Evolution，LTE)等网络中业务体验的一致性和连续性。目前，ICS的一种实现方式是将现网的移动交换中心(Mobile Switch Center，MSC)升级为移动接入网关控制功能(mobile Access Gateway Control Function，mAGCF)设备，使MSC域支持ICS功能，从而实现CS域与IMS域之间的互通。
现网中MSC的升级是个逐步的过程。当MSC没有升级时，需要通过锚定的方式实现IMS域对CS域补充业务的统一控制。例如，如果用户设备(User Equipment，UE)处于CS域，那么当该UE作为主叫用户设备发起呼叫或者作 为被叫用户设备接收呼叫时，该呼叫将被路由至该UE的归属网络的IMS域，由IMS域提供业务。
当UE漫游到拜访网络后，例如UE从本国漫游到他国后，如果仍由该UE的归属网络的IMS域统一控制和提供业务，就需要该UE的拜访网络向该归属网络的IMS域实时返回需要触发的业务的信息，以便归属网络的IMS域根据返回的信息触发相应的业务。然而，拜访网络与归属网络中的IMS域之间会存在一些差异，比如定时器不一致或信令机制不同等，这样在UE作为被叫UE时需要触发的很多业务会无法正常触发，例如对于晚前转业务而言，失败原因值可能无法返回归属网络的IMS域，归属网络的IMS域就无法根据失败原因值触发晚前转业务。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明的一部分实施例，而不是全部实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下获得的所有其他实施例，都属于本发明保护的范围。
本发明的技术方案，可以应用于各种通信网络，例如：全球移动通信系统(Global System of Mobile communication，GSM)网络，码分多址(Code Division Multiple Access，CDMA)网络，宽带码分多址(Wideband Code Division Multiple Access Wireless，WCDMA)网络，通用分组无线业务(General Packet Radio Service，GPRS)网络，长期演进(Long Term Evolution，LTE)网络，通用移动通信系统(Universal Mobile Telecommunication System，UMTS)网络等。
本发明实施例中，UE可以经CS域接入IMS域，用户设备可以是移动终端(Mobile Terminal，MT)，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机。作为示例而非限定，UE可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，这个UE可以与无线接入网交换语音或数据，也可以与无线接入网交换语音和数据。
图1是根据本发明一个实施例的应用场景的示意图。
如图1所示，UE的归属网络包括IMS域110和CS域120。CS域110可以作为IMS域120的接入域，IMS域110可以统一控制UE的业务。CS域120中可以包括关口移动交换中心(Gateway Mobile Switching Center，GMSC)121和HSS 122，GMSC 121可以对UE的呼叫进行路由，HSS 122可以存储UE在归属网络中的签约信息。IMS域110可以包括AS 111、呼叫会话控制功能(Call Session Control Function，CSCF)设备112和媒体网关控制功能(Mobile Gateway Control Function，MGCF)设备113。AS 111是是IMS域110中控制和提供业务的网元。CSCF设备112可以控制呼叫会话。CS域120与IMS域110之间可以通过MGCF设备113进行互通。
当UE漫游至拜访网络后，拜访网络可以包括IMS域，也可以包括IMS域和CS域，也可以包括CS域。在图1中，以拜访网络只包括CS域130为例进行说明。如图1所示，拜访网络的CS域中包括拜访移动交换中心(Visited Mobile Switching Center，VMSC)131。VMSC 131可以对呼叫进行路由。
如图1所示的场景，由于拜访网络只包括CS域130，因此，归属网络可以通过归属网络的CS域120与拜访网络进行通信，也就是归属网络与拜访网络之间开通CS域漫游。在这种情况下，如果仍由归属网络的IMS域110控制UE的业务，那么就需要该UE的拜访网络向该归属网络的IMS域110实时返回需要触发的业务的信息，以便归属网络的IMS域100根据返回的信息触发相应的业务。然而，拜访网络与归属网络中的IMS域100之间会存在一些差异，比如定时器不一致或信令机制不同等，这样在UE作为被叫UE时需要触发的很多业务会无法正常触发。
因此，在本发明实施例中，当另一UE向该UE发起呼叫时，归属网络可以通过归属网络的CS域120将呼叫路由至拜访网络。下面将针对该过程进行详细描述。
图2是根据本发明一个实施例的处理用户业务的方法的示意框图。图2的方法由呼叫控制设备执行。
210，在向被叫UE发起呼叫时，被叫UE的归属网络中的呼叫控制设备接收被叫UE的归属网络中的呼叫路由设备发送的接入域确认请求消息，接入域确认请求消息携带被叫UE的标识。
220，呼叫控制设备根据被叫UE的标识，确定归属网络通过归属网络的CS域与被叫UE的拜访网络进行通信。
230，呼叫控制设备向呼叫路由设备发送接入域确认响应消息，接入域确认响应消息携带指示信息，指示信息用于指示呼叫路由设备通过归属网络的CS域将呼叫路由至拜访网络。
在目前的被叫锚定方案中，如果主叫UE向被叫UE发起呼叫，需要将呼叫锚定回被叫UE的归属网络中的IMS域，通过IMS域将该呼叫接续至被叫UE。即，由IMS域统一控制和提供被叫UE的业务。然而，当被叫UE发生漫游时，例如，被叫UE从本国漫游到他国后，被叫UE处于拜访网络中，拜访网络与归属网络之间的差异会导致归属网络的IMS域无法正常触发某些业务，比如需要向IMS域返回失败原因值才能触发的业务。例如，对于晚前转业务而言，需要将失败原因值返回被叫UE的归属网络的IMS域，IMS域才能为被叫UE触发晚前转业务。然而，由于拜访网络与归属网络之间的定时器差异或信令机制差异等问题，造成拜访网络很难将失败原因值返回归属网络的IMS域，从而造成晚前转业务无法正常触发。晚前转业务，是指呼叫被路由至拜访网络后触发的前转业务，例如被叫UE无应答时的前转业务或者被叫UE忙时的前转业务。
本发明实施例中，主叫UE向被叫UE发起呼叫。当主叫UE向被叫UE发起呼叫时，呼叫控制设备可以确定被叫UE的归属网络是否通过归属网络的CS域与被叫UE的拜访网络进行通信。归属网络通过归属网络的CS域与拜访网 络进行通信，说明归属网络与拜访网络之间的开通CS域漫游，也就是归属网络与拜访网络之间签署CS域漫游协议。在确定归属网络通过归属网络的CS域与拜访网络进行通信的情况下，呼叫控制设备向呼叫路由设备指示通过归属网络的CS域将主叫UE发起的呼叫路由至拜访网络，从而由拜访网络将呼叫路由至被叫UE。换言之，在被叫UE的归属网络通过归属网络的CS域与拜访网络进行通信的情况下，可以通过归属网络的CS域将呼叫路由至被叫UE，而非通过归属网络的IMS域将呼叫路由至被叫UE。通过归属网络的CS域将呼叫路由至被叫UE后，可以由拜访网络的CS域触发和提供被叫UE的业务，这样无需拜访网络实时地向归属网络返回业务的信息，从而能够保证被叫UE的业务的正常触发。例如，针对晚前转业务而言，拜访网络可以直接根据失败原因值触发，而无需将失败原因值返回归属网络，从而能够保证晚前转业务的正常触发。
本发明实施例中，通过呼叫控制设备从呼叫路由设备接收携带被叫UE的标识的接入域确认请求消息，根据被叫UE的标识确定被叫UE的归属网络通过归属网络的CS域与被叫UE的拜访网络进行通信，因此向呼叫路由设备发送携带指示信息的接入域确认响应消息来向指示呼叫路由设备通过归属网络的CS域将呼叫路由至拜访网络，使得CS域能够控制业务的触发，而非IMS域控制业务的触发，因此无需拜访网络向归属网络实时返回业务的信息，从而能够保证正常触发被叫UE的业务。
从上述也可知，IMS域目前处于初步的发展阶段，还尚未广泛部署。这样，拜访网络中可能还没有部署IMS域，归属网络仅能通过归属网络的CS域与拜访网络进行通信，而无法通过归属网络的IMS域与拜访网络进行通信。对于这种场景，本发明实施例更为适用。在这种场景下，如果要求拜访网络的CS域向归属网络的IMS域实时返回业务的信息，由于涉及到两个网络之间的定时器配合以及信令格式转换等问题，因此拜访网络的CS域难以将业务的信息实时 返回归属网络的IMS域。而本发明实施例使得CS域能够控制业务的触发，而非IMS域控制业务的触发，因此无需拜访网络向归属网络实时返回业务的信息，从而能够保证正常触发被叫UE的业务。
本发明实施例中，向被叫UE发起呼叫的主叫UE可以处于CS域中，也可以处于IMS域中。当主叫UE处于CS域时，呼叫控制设备可以是被叫UE的归属网络中的HSS。当主叫UE处于IMS域时，呼叫控制设备可以是被叫UE的归属网络中的AS。
可选地，作为一个实施例，上述的呼叫控制设备可以是HSS。上述呼叫路由设备可以为GMSC。
本发明实施例中，HSS可以指集成了IMS域中HSS、系统架构演进(System Architecture Evolution，SAE)网络中的HSS以及归属位置寄存器(Home Location Register，HLR)的功能的设备，因此，本发明实施例中的HSS也可以称为融合HSS。
可选地，作为另一实施例，在步骤210中，HSS可以接收GMSC发送的接入域确认请求消息。在步骤230中，HSS可以向GMSC发送接入域确认响应消息，接入域确认响应消息可以包括终端移动网络增强型逻辑的客户化应用用户签约信息(Terminating CAMEL(Customized Application for Mobile Network Enhanced Logic，移动网络增强型逻辑的客户化应用)Subscription Information，T_CSI)。T_CSI可以用于指示将通过CS域获取将呼叫路由至拜访网络的漫游号码。
本实施例中，步骤230中的指示信息可以为T_CSI。具体地，当GMSC接收到入局的初始地址消息(Initial Address Message，IAM)之后，GMSC可以根据IAM向HSS发送接入域确认请求消息。IAM可以用于指示主叫UE向被叫UE发起呼叫。IAM是为建立主叫UE与被叫UE之间的呼叫的第一个消息，可以包括确定呼叫路由的相关信息。GMSC向HSS发送的接入域确认请求消 息可以是取路由信息(Send Routing Information，SRI)请求消息。HSS向GMSC返回的接入域确认响应消息可以是SRI_ACK消息，SRI_ACK消息可以包括被叫UE的T_CSI。本实施例中，将此处的SRI请求消息称为第一SRI请求消息，将此处的SRI_ACK消息称为第一SRI_ACK消息。由于被叫UE位于拜访网络，且归属网络通过归属网络的CS域与拜访网络进行通信，因此，T_CSI可以用于指示通过CS域获取漫游号码，漫游号码用于将呼叫路由至拜访网络。可见，此处的T_CSI并不是指向被叫UE的归属网络中的IMS域的AS，这样GMSC就不会将呼叫路由至IMS域。具体而言，GMSC可以根据T_CSI触发取路由信息流程。该流程可以为：GMSC可以向HSS发送第二SRI请求消息，第二SRI请求消息用于请求漫游号码。HSS可以根据第二SRI消息向VMSC发送提供漫游号码(Provide Roaming Number，PRN)消息。VMSC可以根据PRN消息向HSS发送PRN响应消息(PRN_ACK)消息，其中PRN_ACK消息可以携带漫游号码。HSS可以向GMSC发送第二SRI_ACK消息，第二SRI_ACK消息可以携带该漫游号码。这样，GMSC可以根据漫游号码将呼叫路由至VMSC，由VMSC将呼叫路由至被叫UE。
当被叫UE漫游至拜访网络后，为了能够保证被叫UE的正常通信，首先需要在拜访网络中注册，也就是需要进行位置更新。可选地，作为另一实施例，在步骤210之前，HSS可以接收拜访网络中的VMSC发送的位置更新请求消息，位置更新请求消息携带被叫UE的标识。HSS可以在归属网络通过归属网络的CS域与拜访网络进行通信的情况下，根据被叫UE的标识，向VMSC发送插入数据请求消息，插入数据请求消息携带被叫UE在归属网络中签约时所存储的用户信息，以通知VMSC根据用户信息在拜访网络中对被叫UE进行注册。
具体地，上述用户信息可以包括被叫UE在归属网络中签约的业务的信息。用户信息还可以包括被叫UE的标识等信息。在被叫UE发起位置更新请求时， 由于被叫UE位于拜访网络，而归属网络通过归属网络的CS域与拜访网络进行通信，HSS可以向VMSC发送被叫UE在归属网络中签约的业务的信息，由VMSC来控制被叫UE的业务的触发，这样能够保证正常触发被叫UE的业务。
可选地，作为另一实施例，上述用户信息可以包括晚前转业务信息。这样，被叫UE的晚前转业务可以由VMSC来触发。此外，HSS可以向VMSC发送的用户信息还可以其它与晚前转业务类似的业务的信息，比如需要根据失败原因值来触发的业务的信息。
可选地，作为另一实施例，位置更新请求消息可以包括拜访位置寄存器(Visited Location Register，VLR)号码(Number)。HSS可以根据VLR的号码以及VLR号码与漫游协议之间的对应关系，确定拜访网络与归属网络之间的漫游协议。HSS可以根据拜访网络与归属网络之间的漫游协议，确定归属网络通过归属网络的CS域与拜访网络进行通信。
具体而言，VLR号码可以标识VLR。VLR可以设置于VMSC内，通常VLR号码与VMSC号码是相同的。可以预先在HSS内存储VLR号码与漫游协议之间的对应关系，这样，获取VLR号码后，可以确定拜访网络与归属网络之间漫游协议。漫游协议可以指拜访网络与归属网络之间开通的漫游方式。漫游方式可以指归属网络通过归属网络的CS与还是IMS域与拜访网络进行通信。这样，HSS根据拜访网络与归属网络之间的漫游协议，就可以确定归属网络通过归属网络的CS域与拜访网络进行通信。
此外，HSS可以存储VLR的号码。在步骤220中，HSS可以根据被叫UE的标识获取VLR的号码，可以根据HSS内存储的VLR号码与漫游协议之间的对应关系，确定拜访网络与归属网络之间漫游协议。HSS根据拜访网络与归属网络之间的漫游协议，就可以确定归属网络通过归属网络的CS域与拜访网络进行通信。
另外，在AS向HSS请求接入域信息时，HSS可以根据存储的VLR的号 码确定接入域信息，接入域信息可以用于指示归属网络通过归属网络的CS域与拜访网络进行通信。然后HSS可以将接入域信息发送给AS。
可选地，作为另一实施例，HSS还可以从归属网络的AS接收接入域信息请求消息，接入域信息请求消息用于请求接入域信息。HSS可以根据接入域信息请求消息，向AS发送接入域信息响应消息，接入域信息响应消息可以携带接入域信息，接入域信息可以用于指示归属网网络通过归属网络的CS域与拜访网络进行通信。
可选地，作为另一实施例，HSS还可以接收归属网络中的AS发送的数据更新请求消息，数据更新请求消息用于指示被叫UE请求设置补充业务。HSS可以在归属网络通过归属网络的CS域与拜访网络进行通信的情况下，对补充业务进行检查。HSS可以向AS发送数据更新响应消息，数据更新响应消息携带设置补充业务成功的标识或设置补充业务失败的标识。。
为了向用户提供更多丰富的业务，提升用户体验，现有网络能够支持用户根据实际需求在UE中设置一些补充业务。目前，在CS域中，UE可以采用非结构化补充业务数据(Unstructured Supplementary Service Data，USSD)方式来设置补充业务。在IMS域中，UE可以通过Ut接口来设置补充业务。当UE位于拜访网络，UE的归属网络通过归属网络的CS域与拜访网络进行通信，UE可能通过USSD方式设置补充业务，也可能通过Ut接口设置补充业务，由于CS域中对补充业务的检查标准与IMS域中对补充业务的检查标准是不同的，因此可能会导致业务经过两套不同的检查标准，导致对业务的设置不一致。
因此AS在接收到被叫UE通过Ut接口发送的补充业务设置请求消息后，不对补充业务进行检查，向HSS发送数据更新请求消息，由HSS根据数据更新请求消息对补充业务进行检查，从而能够避免补充业务经过不同的检查标准，造成业务的不一致。
上述描述了当主叫UE位于CS域时由HSS执行图2的方法的过程。下面 将描述当主叫UE位于IMS域时的具体过程。
可选地，作为另一实施例，上述呼叫控制设备可以是AS，呼叫路由设备可以是呼叫会话控制功能(Call Session Control Function，CSCF)设备。
当主叫UE位于IMS域时，主叫UE从IMS域向被叫UE发起呼叫。此时，需要被叫UE的归属网络中的IMS域的相应设备来进行处理。AS是IMS域中控制和提供业务的网元。
可选地，作为另一实施例，在步骤210中，AS可以接收CSCF设备发送的接入域确认请求消息。在步骤230中，AS可以向CSCF设备发送接入域确认响应消息，该响应消息可以包括特殊号码，该特殊号码用于指示CSCF设备通过归属网络的CS域将呼叫路由至拜访网络。
本实施例中，步骤230中的指示信息可以是特殊号码。具体地，CSCF设备在接收到主叫UE在IMS域发起的会话请求消息后，可以根据会话请求消息向AS发送接入域确认请求消息，接入域确认请求消息可以携带被叫UE的标识，例如被叫号码。由于被叫UE位于拜访网络，并且归属网络通过归属网路中的CS域与拜访网络进行通信，因此AS可以不进行业务触发，向CSCF设备返回包括特殊号码的接入域确认响应消息，以便由CS域来控制业务的触发。该特殊号码可以是在被叫号码之前增加的号码前缀，CSCF设备可以根据特殊号码，将呼叫路由至媒体网关控制功能(Media Gateway Control Function，MGCF)设备。MGCF设备是实现IMS域与CS域互通的网元。MGCF设备可以再将呼叫路由至GMSC，GMSC然后触发取路由信息流程，该流程可以参见上面GMSC触发的取路由信息流程，不再赘述。通过取路由信息流程，GMSC可以获取漫游号码，然后可以根据漫游号码将呼叫路由至VMSC，从而由VMSC将呼叫路由至被叫UE。
可选地，作为另一实施例，在步骤220中，AS可以向HSS发送接入域信息请求消息，接入域信息请求消息用于请求接入域信息。AS可以从HSS接收 接入域响应消息，接入域信息响应消息携带接入域信息，接入域信息用于指示归属网络通过归属网络的CS域与拜访网络进行通信。
为了向用户提供更多丰富的业务，提升用户体验，现有网路支持用户根据实际需求在UE中设置一些补充业务。目前，在CS域中，UE可以采用USSD方式来设置补充业务。在IMS域中，UE可以通过Ut接口来设置补充业务。当UE位于拜访网络，UE的归属网络通过归属网络的CS域与拜访网络进行通信，UE可能通过USSD方式设置补充业务，也可能通过Ut接口设置补充业务，由于CS域中对补充业务的检查标准与IMS域中对补充业务的检查标准是不同的，因此可能会导致业务经过两套不同的检查标准，导致对业务的设置不一致。
可选地，作为另一实施例，AS可以接收被叫UE发送的补充业务设置请求消息，补充业务设置请求消息用于指示被叫UE请求设置补充业务。AS可以在归属网络通过归属网络的CS域与拜访网络进行通信的情况下，向HSS发送数据更新请求消息，数据更新请求消息用于指示被叫UE请求设置补充业务。AS可以接收HSS发送的数据更新响应消息，数据更新响应消息携带设置补充业务成功的标识或设置补充业务失败的标识。AS可以向被叫UE发送补充业务设置响应消息，补充业务设置响应消息携带设置补充业务成功的标识或设置补充业务失败的标识。
具体地，被叫UE位于拜访网络，且归属网络通过归属网络的CS域与拜访网络进行通信，因此AS在接收到被叫UE通过Ut接口发送的补充业务设置请求消息后，可以不对补充业务进行检查，向HSS发送数据更新请求消息。这样由HSS根据数据更新请求消息对补充业务进行检查。数据更新请求消息可以携带被叫UE设置的补充业务的信息。
HSS在对补充业务检查后，如果补充业务通过检查，则HSS可以将补充业务的信息进行存储，并可以向AS发送数据更新响应消息，该数据更新响应消息可以携带设置补充业务成功的标识。设置补充业务成功的标识可以指示补 充业务设置成功。如果补充业务没有通过检查，则HSS不存储补充业务的相关信息，然后向AS发送数据更新响应消息，该数据更新响应消息可以用于指示设置补充业务失败的标识。设置补充业务失败的标识可以指示补充业务设置失败。AS可以根据HSS的数据更新响应消息，向UE发送补充业务设置响应消息。如果数据更新响应消息携带设置补充业务成功的标识，则补充业务设置响应消息也携带设置补充业务成功的标识；如果数据更新响应消息携带设置补充业务失败的标识，则补充业务设置响应消息也携带设置补充业务失败的标识。本实施例中，由于AS对被叫UE请求设置的补充业务不进行业务检查，而由HSS进行检查，能够避免补充业务经过两套检查标准，从而能够避免补充业务的不一致性。
上面描述了针对被叫UE的呼叫业务的处理过程。下面将描述UE进行位置更新的过程。
在现有的方案中，当UE在拜访网络发起位置更新时，如果该UE的归属网络中的IMS域统一控制和提供业务，那么IMS域无需向拜访网络发送该UE在归属网络中签约的业务的信息，例如晚前转业务。然而，如上所述，由于UE漫游在拜访网络，如果仍由该UE的归属网络中的IMS域统一控制和提供业务，会造成无法正常触发UE的业务。
图3a是根据本发明另一实施例的处理用户业务的方法的示意性流程图。
310a，UE的归属网络中的HSS接收UE的拜访网络中的VMSC发送的位置更新请求消息，位置更新请求消息携带UE的标识。
320a，HSS根据UE的标识，确定归属网络是否通过归属网络的CS域与拜访网络进行通信。
330a，HSS在确定归属网络通过归属网络的CS域与拜访网络进行通信的情况下，向VMSC发送插入数据请求消息，插入数据请求消息携带UE在归属网络中签约时所存储的用户信息，以通知VMSC根据用户信息在拜访网络中对 UE进行注册。
用户信息可以包括UE在归属网络中签约的业务的信息。
本发明实施例中，通过在确定归属网络通过归属网络的CS域与拜访网络进行通信的情况下，向VMSC发送插入数据请求消息，插入数据请求消息携带UE在归属网络中签约时所存储的用户信息，使得VMSC能够根据用户信息控制UE的业务的触发，从而能够保证正常触发UE的业务。
可选地，作为一个实施例，位置更新请求消息可以包括VLR号码。在步骤320a中，HSS可以根据VLR的号码以及VLR号码与漫游协议之间的对应关系，确定拜访网络与归属网络之间的漫游协议。HSS可以根据拜访网络与所述归属网络之间的漫游协议，确定归属网络通过归属网络的CS域与拜访网络进行通信。
可选地，作为另一实施例，上述用户信息可以包括晚前转业务信息。
HSS可以向VMSC发送晚前转业务信息，这样，在UE作为被叫UE时，晚前转业务可以由VMSC根据晚前转业务信息来触发。这种情况下，无需拜访网络将失败原因值返回归属网络，从而能够保证晚前转业务的正常触发。
可选地，作为另一实施例，HSS还可以从归属网络的AS接收接入域信息请求消息，接入域信息请求消息用于请求接入域信息。HSS可以向AS发送接入域信息响应消息，接入域信息响应消息可以携带接入域信息，接入域信息可以用于指示归属网络是否通过归属网络的CS域与拜访网络进行通信。由于对于AS而言，需要根据接入域信息判断是否控制UE的业务。AS可以从HSS获取接入域信息。
可选地，作为另一实施例，HSS还可以接收归属网络的AS发送的数据更新请求消息，数据更新请求消息用于指示UE请求设置补充业务。HSS可以在确定归属网络通过归属网络的CS域与拜访网络进行通信的情况下，对补充业务进行检查。HSS可以向AS发送数据更新响应消息，数据更新响应消息携带 设置补充业务成功的标识或设置补充业务失败的标识。应理解，如果数据更新响应消息携带设置补充业务成功的标识，则补充业务设置响应消息也携带设置补充业务成功的标识；如果数据更新响应消息携带设置补充业务失败的标识，则补充业务设置响应消息也携带设置补充业务失败的标识。本实施例中，由于AS对UE请求设置的补充业务不进行业务检查，而由HSS进行检查，能够避免补充业务经过两套检查标准，从而能够避免补充业务的不一致性。
目前，在CS域中，UE可以采用USSD方式来设置补充业务。在IMS域中，UE可以通过Ut接口来设置补充业务。当UE位于拜访网络，且UE的归属网络通过归属网络的CS域与拜访网络进行通信，UE可能通过USSD方式设置补充业务，也可能通过Ut接口设置补充业务，由于CS域中对补充业务的检查标准与IMS域中对补充业务的检查标准是不同的，因此可能会导致业务经过两套不同的检查标准，导致对业务的设置不一致。下面将描述本发明实施例中UE设置补充业务的过程。
图3b是根据本发明另一实施例的处理用户业务的方法的示意性流程图。
310b，UE的归属网络中的AS接收UE发送的补充业务设置请求消息，补充业务设置请求消息用于指示UE请求设置补充业务。
320b，AS确定归属网络是否通过归属网络的CS域与UE的拜访网络进行通信。
330b，AS在确定归属网络通过归属网络的CS域与拜访网络进行通信的情况下，不对补充业务进行检查，并向归属网络中的HSS发送数据更新请求消息，以便HSS根据数据更新请求消息对补充业务进行检查。
本发明实施例中，通过AS在确定归属网络通过归属网络的CS域与拜访网络进行通信的情况下，不对补充业务进行检查，并向归属网络中的HSS发送数据更新请求消息，使得HSS对补充业务进行检查，能够避免补充业务经过两套检查标准，从而能够避免补充业务的不一致性。
可选地，作为一个实施例，在步骤320b中，AS可以向HSS发送接入域信息请求消息，接入域信息请求消息携带UE的标识。AS可以接收HSS发送的接入域信息响应消息，接入域信息响应消息携带接入域信息，接入域信息用于指示归属网络是否通过归属网络的CS域与拜访网络进行通信。
从上述可知，HSS负责UE的位置更新。当UE向VMSC发起位置更新请求时，HSS可以从VMSC获取VLR的号码，从而根据VLR的号码确定接入域信息。AS可以从HSS获取接入域信息。
可选地，作为另一实施例，在步骤330b之后，AS可以接收HSS发送的数据更新响应消息，数据更新响应消息携带设置补充业务成功的标识或设置补充业务失败的标识。AS还可以向UE发送补充业务设置响应消息，补充业务设置响应消息携带设置补充业务成功的标识或设置补充业务失败的标识。应理解，如果数据更新响应消息携带设置补充业务成功的标识，则补充业务设置响应消息也携带设置补充业务成功的标识；如果数据更新响应消息携带设置补充业务失败的标识，则补充业务设置响应消息也携带设置补充业务失败的标识。
下面将结合具体例子详细描述本发明实施例。应理解，下面的例子仅是为了帮助本领域技术人员更好地理解本发明实施例，而非限制本发明实施例的范围。
图4是根据本发明一个实施例的处理用户业务的方法的过程的示意性流程图。在图4中，假设向被叫UE发起呼叫的主叫UE位于CS域。
401，GMSC接收入局的第一IAM，第一IAM可以用于指示主叫UE向被叫UE发起呼叫。
402，GMSC根据IAM，向HSS发送第一SRI消息，第一SRI消息可以用于指示主叫UE向被叫UE发起呼叫，第一SRI消息可以携带被叫UE的标识。
403，HSS根据第一SRI消息，确定被叫UE的归属网络是否通过归属网络的CS域与拜访网络进行通信。
例如，HSS可以是在被叫UE发起位置更新的过程中获取VLR的号码，并将VLR的号码进行存储。在步骤403中，HSS可以根据被叫UE的标识，获取存储的VLR的号码。根据VLR的号码以及VLR号码与漫游协议之间的对应关系，确定拜访网络与归属网络之间的漫游协议。然后HSS可以根据拜访网络与归属网络之间的漫游协议，确定被叫UE的归属网络是否通过归属网络的CS域与拜访网络进行通信。
404，在归属网络通过归属网络的CS域与拜访网络进行通信的情况下，HSS向GMSC发送第一SRI_ACK消息，第一SRI_ACK消息包括被叫UE的T_CSI。
在图4中，假设被叫UE的归属网络通过归属网络的CS域与拜访网络进行通信，而无法通过归属网络的IMS域与拜访网络进行通信。T_CSI用于指示GMSC通过归属网络的CS域获取将呼叫路由至拜访网络的漫游号码。
应理解，如果归属网络可以通过归属网络的IMS域与拜访网络进行通信，那么HSS可以向GMSC发送锚定T_CSI，锚定T_CSI用于指示GMSC将呼叫路由至归属网络中的AS。具体过程可以参照现有的过程，不再赘述。
405，GMSC根据T_CSI，向HSS发送第二SRI消息，第二SRI消息用于请求漫游号码。
406，HSS向VMSC发送PRN消息，PRN消息用于请求漫游号码。

408，HSS向GMSC发送第二SRI_ACK消息，第二SRI_ACK消息包括漫游号码，漫游号码用于将呼叫路由至拜访网络。
409，GMSC根据漫游号码向VMSC发送第二IAM，第二IAM用于将呼叫路由至VMSC。
410，VMSC根据第二IAM，将呼叫路由至被叫UE。
本发明实施例中，通过在归属网络是否通过归属网络的CS域与拜访网络 进行通信的情况下，向GMSC发送被叫UE的T_CSI，T_CSI用于指示GMSC通过归属网络的CS域获取将呼叫路由至拜访网络的漫游号码，使得GMSC通过归属网络的CS域将呼叫路由被叫UE，从而使得CS域能够控制业务的触发，而非IMS域控制业务的触发，因此无需拜访网络向归属网络实时返回业务的信息，从而能够保证正常触发被叫UE的业务。
图5是根据本发明另一实施例的处理用户业务的方法的过程的示意性流程图。在图5中，假设向被叫UE发起呼叫的主叫UE位于IMS域，主叫UE与被叫UE在同一个归属网络中签约。
501，第二UE向CSCF设备发送会话请求消息，会话请求消息可以用于指示主叫UE向被叫UE发起呼叫，会话请求消息可以携带被叫UE的标识，例如被叫号码。
502，CSCF设备根据会话请求消息，向AS发送接入域确认请求消息，接入域确认请求消息可以携带被叫UE的标识。
503，AS根据被叫UE的标识，向HSS发送接入域信息请求消息，该接入域信息请求消息用于请求接入域信息。
504，HSS根据接入域信息请求消息，向AS发送接入域信息。
505，在接入域信息用于指示归属网络通过归属网络的CS域与拜访网络进行通信的情况下，AS向CSCF设备发送接入域确认响应消息，接入域确认响应消息包括特殊号码，特殊号码用于指示将通过归属网络的CS域将呼叫路由至拜访网络。
在图5中，假设被叫UE的归属网络通过归属网络的CS域与拜访网络进行通信，无法通过归属网络的IMS域与拜访网络进行通信。
为了CS域进行业务控制，因此在归属网络通过归属网络的CS域与拜访网络进行通信的情况下，AS不进行业务处理，可以生成特殊号码。特殊号码可以是在被叫号码之间的号码前缀。
应理解，如果接入域信息指示归属网络可以通过归属网络的IMS域与拜访网络进行通信，那么AS可以对该呼叫进行处理，即可以按照现有的IMS域处理呼叫业务的流程执行。
506，CSCF设备根据特殊号码，向MGCF设备发送会话请求消息。
换句话说，CSCF设备根据特殊号码，将呼叫路由至MGCF设备。
507，MGCF设备向GMSC发送会话请求消息。
具体而言，MGCF设备将呼叫路由至GMSC。
步骤508至步骤513与图4的步骤405至410类似，不再赘述。
本发明实施例中，通过在归属网络通过归属网络的CS域与拜访网络进行通信的情况下，AS向CSCF设备发送的接入域确认响应消息包括特殊号码，特殊号码用于指示将通过归属网络的CS域将呼叫路由至拜访网络，使得CS域能够控制业务的触发，而非IMS域控制业务的触发，因此无需拜访网络向归属网络实时返回业务的相关信息，从而能够保证正常触发被叫UE的业务。
图6是根据本发明另一实施例的处理用户业务的方法的过程的示意性流程图。在图6中，HSS位于UE的归属网络中。
601，UE向VMSC发送位置更新请求消息，位置更新请求消息携带UE的标识。
具体地，位置更新请求消息可以用于指示UE请求在拜访网络进行注册，由于UE漫游至拜访网络时，拜访网络没有UE的信息，因此UE需要通过发起位置更新请求，来完成在拜访网络中的注册，这样，UE就能够通过拜访网络使用业务。
602，VMSC向HSS发送UE的位置更新请求消息。
603，HSS根据UE的标识，确定UE的归属网络是否通过归属网络的CS域与拜访网络进行通信。
位置更新请求消息还可以包括VLR的号码。HSS可以根据VLR的号码确 定UE的归属网络是否通过归属网络的CS域与拜访网络进行通信。
具体过程可以参照图4中的步骤403，不再赘述。
604，在归属网络通过归属网络的CS域与拜访网络进行通信的情况下，HSS向VMSC发送插入数据请求消息，插入数据请求消息包括UE在归属网络中签约时所存储的用户信息。
例如，用户信息包括UE在归属网络签约的业务的信息。UE在归属网络签约的业务可以包括晚前转业务。
应理解，如果归属网络可以通过归属网络的IMS域与拜访网络进行通信，那么插入数据请求消息中用户信息可以不包括晚前转业务信息。
605，VMSC在保存UE的用户信息后，向HSS发送插入数据响应消息。
VMSC保存UE的用户信息后，就完成了UE在拜访网络中的注册。
606，VMSC向UE发送位置更新响应消息，位置更新响应消息用于指示UE的位置更新成功。
本发明实施例中，通过在确定归属网络通过归属网络的CS域与拜访网络进行通信的情况下，向VMSC发送插入数据请求消息，插入数据请求消息携带UE在归属网络中签约时所存储的用户信息，使得VMSC能够根据用户信息控制UE的业务的触发，从而能够保证正常触发UE的业务。

703，HSS向AS发送接入域信息响应消息，接入域信息响应消息携带接入域信息。
704，在接入域信息指示归属网络通过归属网络的CS域与拜访网络进行通信的情况下，AS不对补充业务进行检查，向HSS发送数据更新请求消息。
在图7中，假设UE的归属网络通过归属网络的CS域与拜访网络进行通信，无法通过归属网络的IMS域与拜访网络进行通信。
数据更新请求消息可以用于指示UE请求设置补充业务，例如，数据更新请求消息可以携带UE的标识以及补充业务的信息。
705，HSS对补充业务进行检查。
706，HSS向AS发送数据更新响应消息。
数据更新响应消息携带设置补充业务成功的标识或设置补充业务失败的标识。
在步骤705中，如果HSS对补充业务检查成功，则保存补充业务的信息，此时数据更新响应消息携带设置补充业务成功的标识。如果HSS对补充业务检测失败，则数据更新响应消息携带设置补充业务失败的标识。
707，AS向UE发送补充业务设置响应消息。
如果数据更新响应消息携带设置补充业务成功的标识，则补充业务设置响应消息携带设置补充业务成功的标识；如果数据更新响应消息携带设置补充业务失败的标识，则补充业务设置响应消息携带设置补充业务失败的标识。
应理解，如果接入域信息指示归属网络可以通过归属网络的IMS域与拜访网络进行通信，那么AS对补充业务进行检查，AS可以向HSS发送检查后的补充业务的信息，HSS可以保存补充业务的信息。此时，HSS不对补充业务进行检查。
本发明实施例中，通过AS在确定归属网络通过归属网络的CS域与拜访网络进行通信的情况下，不对补充业务进行检查，并向归属网络中的HSS发送数据更新请求消息，使得HSS对补充业务进行检查，能够避免补充业务经过两套检查标准，从而能够避免补充业务的不一致性。
