Description

状态信息获取方法、业务控制点及服务器
本申请要求于2013年12月26日提交中国专利局、申请号为201310731825.6、发明名称为“状态信息获取方法、业务控制点及服务器”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
本发明实施例涉及通信技术，尤其涉及一种状态信息获取方法、业务控制点及服务器。
背景技术
目前，在第二代移动通信(the 2nd Generation Mobile Communication，2G)/第三代移动通信(the 3rd Generation Mobile Communication，3G)网络中，除了号码显示、呼叫限制等业务外，还存在大量的智能业务，如预付费业务(Prepaid Service，PPS)、虚拟专用号码(Virtual Private Number，VPN)业务等。智能业务通过智能网来提供，提供智能业务的服务器称之为业务控制点(Service Control Point，SCP)。随着技术的不断发展，2G/3G网络逐渐向长期演进(Long Term Evolution，LTE)网络发展。虽然LTE网络可直接向用户提供智能业务，但是，一方面，由于大多数营运商仍然希望传统的智能网给用户继续提供服务；另一方面，由于LTE处于初级阶段，在很长时期内，LTE网络、2G/3G网络与传统的智能网将处于共存的状态，因此，需要LTE网络与智能网实现互通。
一般来说，在智能网实现智能业务的过程中，SCP需要获知用户的状态，如用空闲、忙碌、不可及等。现有技术中，在LTE网络、2G/3G网络与传统的智能网共存的状态下，通过对SCP进行升级，使SCP支持第三代移动通信伙伴组织(3rd Generation Partnership Project，3GPP)第9版(Relase9，R9)定义的任意时间查询(Anytime Interrogation，ATI)命令、演进的分组系统(Evolved Packet System，EPS)位置和状态的获取以及终结接入域选择(Terminating ADS， T-ADS)等功能来获取用户所在的接入域。
然而，上述技术方案中，必须对SCP进行复杂的升级才能使其支持3GPP的R9的相关协议等，过程复杂不宜实施，且代价比较大。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，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，所描述的实施例是本发明一部分实施例，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他实施例，都属于本发明保护的范围。
图1为本发明状态信息获取方法实施例一的流程图。本实施例是SCP的角度对本发明进行详细阐述，本实施例适用于LTE网络、2G/3G网络与传统的智能网共存的状态下，SCP需要获取用户设备的状态信息的场景。具体的，本实施例包括如下步骤：
101、SCP向归属用户服务器(Home Subscriber Server，HSS)发送ATI请求，ATI请求携带状态标识以及用户设备的标识。
本发明实施例中的用户设备，具体为可驻留在LTE网络中的用户设备，也可以为驻留在2G/3G网络中的用户设备，例如本发明实施例中的用户设备可以是单射频(Single Radio，SR)手机(亦称单待手机)或者双待手机等。在2G/3G网络与LTE网络共同覆盖的场景下，单待手机一般只驻留在一个网络，即要么驻留在2G/3G网络，要么驻留在LTE网络。
本步骤中，SCP在需要获取用户设备状态信息的时候，SCP向HSS发送携带状态标识以及用户设备的标识的ATI请求，使得HSS进行T-ADS，即由HSS确定用户设备当前所处的网络。其中，用户设备的标识指示具体的用户设备，状态标识用于指示SCP需要获取的是用户设备处于空闲、忙碌等状态的状态信息而非位置信息或其他信息等。当HSS确定出用户设备驻留在2G/3G网络时，此时，用户设备的状态信息由HSS通过提供用户消息(Provide Subscriber Information，PSI)到该用户设备附着的拜访移动交换中心(Visit Mobile Switch Centre，VMSC)查询并获取，具体可参见现有技术，此处不再赘述；而当HSS确定出用户设备驻留在LTE网络时，此时，用户设备的状态信息可以由HSS从电话应用服务器(Telephony Application Server，TAS)查询并获取。
102、SCP接收HSS发送的ATI响应，ATI响应携带HSS从TAS获取的用户设备的状态信息。
SCP接收HSS发送的携带用户设备的状态信息的ATI响应。可选的，HSS可以直接从TAS中查询到用户设备的状态信息并携带在ATI响应中向SCP发送；或 者，当用户设备的状态信息发生更新后，TAS向HSS发送该用户设备更新后的状态信息，然后，HSS将该更新后的状态信息发送给SCP。作为示例而非限定，当用户设备的状态信息发生变化，例如，用户设备的呼叫状态从忙碌改变为空闲或从空闲改变为忙碌时，TAS可将用户设备当前的状态信息发送给HSS。此时，若SCP需要获取用户设备的状态信息，则可向HSS发送ATI请求，当HSS确定出用户处于LTE网络时，无需再到TAS查询并获取，而是直接将用户设备更新后的状态信息携带在ATI响应中发送给SCP。
本发明实施例提供的状态信息获取方法，在需要获取用户设备状态信息的时候，SCP通过向HSS发送ATI请求，当HSS确定出用户设备处于LTE网络时，由HSS直接从TAS获取状态信息并向SCP发送，或者无需到TAS查询而将TAS发送的更新后的状态信息直接发送给SCP，使得SCP在智能网中实现智能业务。该方法中，SCP无需感知LTE网络，无需对SCP进行复杂升级使其支持3GPP的R9相关的ATI命令、接入域选择等功能，在LTE网络、2G/3G网络与传统的智能网共存的状态下，并在对SCP不进行复杂升级的前提下，实现用户状态信息的获取。另外，现有技术中HSS在从VMSC获取用户设备的状态信息时，只能获取到用户设备在EPC网络的承载状态(如激活承载、未注册、注册等)，而非用户设备真正的呼叫相关状态，本实施例中，用户设备的状态信息由HSS从TAS获取并发送给SCP，由于TAS中存储的是用户设备的呼叫状态的信息，因此实现了用户设备状态信息的真正获取。
图2为本发明状态信息获取方法实施例二的流程图。本实施例是从HSS的角度对本发明进行详细阐述，本实施例适用于LTE网络、2G/3G网络与传统的智能网共存的状态下，SCP需要获取用户设备的状态信息的场景。具体的，本实施例包括如下步骤：
201、HSS接收SCP发送的ATI请求，ATI请求携带状态标识以及用户设备的标识。
本步骤中，SCP在需要获取用户设备状态信息的时候，SCP向HSS发送ATI请求。相应的，HSS接收SCP发送的ATI请求。
202、HSS确定用户设备所处的接入域，接入域包括：LTE网络、2G网络或3G网络。
在接收到SCP发送的ATI请求后，HSS从移动性管理实体(Mobility  Management Entity，MME)、服务GPRS支持节点(Serving GPRS Support Node，SGSN)等获取T-ADS信息从而进行T-ADS，确定用户设备的接入域。
需要说明的是，由于LTE网络与智能网实现互通引发的状态信息获取的问题，是由于网络架构中引入LTE网络的缘故。因此，本发明实施例中，HSS只需要区分用户设备处于LTE网络或非LTE网络即可。当用户设备处于非LTE网络，即处于2G或3G网络时，HSS无需进一步详细区分出用户设备具体处于2G网络或3G网络。
203、若HSS确定用户设备处于LTE网络，则HSS向SCP发送ATI响应，ATI响应携带HSS从TAS获取的用户设备的状态信息。
本步骤中，若HSS执行T-ADS确定出用户设备处于2G/3G网络，则向该用户设备附着的VMSC查询发送PSI消息以获取状态信息，具体可参见现有技术，此处不再赘述；而若HSS执行T-ADS确定出用户设备处于LTE网络时，则向SCP发送携带HSS从TAS获取的用户设备的状态信息ATI响应。
本发明实施例提供的状态信息获取方法，在需要获取用户设备状态信息的时候，HSS在接收到SCP发送的ATI请求后，进行T-ADS确定用户设备的接入域。当HSS确定出用户设备处于LTE网络时从TAS获取用户设备的状态信息，并将状态信息携带在ATI响应中发送给SCP，使得SCP在智能网中实现智能业务。该方法中，SCP无需感知LTE网络，无需对SCP进行复杂升级使其支持3GPP的R9相关的ATI命令、接入域选择等功能，在LTE网络、2G/3G网络与传统的智能网共存的状态下，并在对SCP不进行复杂升级的前提下，实现用户状态信息的获取。另外，现有技术中HSS在从VMSC获取用户设备的状态信息时，只能获取到用户设备在EPC网络的承载状态(如激活承载、未注册、注册等)，而非用户设备真正的呼叫相关状态，本实施例中，用户设备的状态信息由HSS从TAS获取并发送给SCP，由于TAS中存储的是用户设备的呼叫状态的信息，因此实现了用户设备状态信息的真正获取。
可选的，上述实施例二中，HSS向SCP发送ATI响应之前，可向TAS发送状态信息获取请求，该状态信息获取请求携带用户设备的标识，使得TAS在确定用户设备的状态信息后，通过状态信息获取响应向HSS发送用户设备的状态信息，从而使得HSS将状态信息携带在ATI响应中发送给SCP。
可选的，上述实施例二中，HSS向SCP发送ATI响应之前，可接收TAS在用 户设备的状态发生变化时发送的信息更新请求(Profile Update Request，PUR)，该PUR携带用户设备更新后的状态信息。相应的，HSS向所述SCP发送的ATI响应携带用户设备更新后的状态信息。
具体的，当用户设备的状态信息发生变化，例如，用户设备的呼叫状态从忙碌改变为空闲或从空闲改变为忙碌等时，TAS可将用户设备当前的状态信息通过PUR消息发送给HSS。相应的，HSS接收TAS发送的PUR并向TAS发送信息更新应答(Profile Update Answer，PUA)，其中，PUR携带用户设备更新后状态信息。当SCP重新需要确定用户设备的状态信息时，若HSS确定出用户设备处于LTE网络，则无需再到TAS查询并获取，而是直接将用户设备更新后的状态信息携带在ATI响应中发送给SCP。
图3为本发明状态信息获取方法实施例三的流程图。本实施例是从TAS的角度对本发明进行详细阐述，本实施例适用于LTE网络、2G/3G网络与传统的智能网共存的状态下，SCP需要获取用户设备的状态信息的场景。具体的，本实施例包括如下步骤：
301、TAS确定用户设备的状态信息。
SCP在需要获取用户设备状态信息的时候，TAS确定用户设备的状态信息。
302、TAS向HSS发送状态信息，以触发HSS将用户设备的状态信息发送给SCP。
在确定出用户设备的状态信息后，TAS将确定出的状态信息发送给HSS，以使得HSS将该状态信息发送给SCP。
本发明实施例提供的状态信息获取方法，在需要获取用户设备状态信息的时候，并确定出用户设备处于LTE网络时的状态信息获取请求，TAS确定出用户设备的状态信息并向HSS发送状态信息获取响应，进而由HSS将获取到的状态信息发送给SCP，使得SCP在智能网中实现智能业务。该方法中，SCP无需感知LTE网络，无需对SCP进行复杂升级使其支持3GPP的R9相关的ATI命令、接入域选择等功能，在LTE网络、2G/3G网络与传统的智能网共存的状态下，并在对SCP不进行复杂升级的前提下，实现用户状态信息的获取。另外，现有技术中HSS在从VMSC获取用户设备的状态信息时，只能获取到用户设备在EPC网络的承载状态(如激活承载、未注册、注册等)，而非用户设备真正的呼叫相关状态，本实施例中，用户设备的状态信息由HSS从TAS获取并发送给SCP， 由于TAS中存储的是用户设备的呼叫状态的信息，因此实现了用户设备状态信息的真正获取。
可选的，上述实施例三中，TAS在确定用户设备的状态信息之前，可以接收HSS发送的状态信息获取请求，该状态信息获取请求携带用户设备的标识。此时，TAS根据状态信息获取请求携带的用户设备的标识，确定用户设备的状态信息，并将该状态信息携带在状态信息获取响应中发送给HSS，从而触发HSS向SCP发送用户设备的状态信息。
可选的，上述实施例三中，TAS在确定用户设备的状态信息之前，需要确定用户设备的呼叫状态是否改变，若未改变，则无需动作；否则，若确定出用户设备的呼叫状态发生改变，则TAS向HSS发送信息更新请求PUR，并接收HSS发送的信息更新应答PUA，其中，PUR携带用户设备更新后的状态信息。
具体的，当用户设备的状态信息发生变化，例如，用户设备的呼叫状态从忙碌改变为空闲或从空闲改变为忙碌时，TAS可将用户设备当前的状态信息发送给HSS。此时，若SCP需要获取用户设备的状态信息，则可向HSS发送ATI请求，当HSS确定出用户处于LTE网络时，无需再到TAS查询并获取，而是直接将用户设备更新后的状态信息携带在ATI响应中发送给SCP。
上述图1、图2与图3实施例分别从SCP、HSS以及TAS的角度对本发明进行了详细说，下面，从SCP、HSS以及TAS进行信令交互的角度对本发明进行详细阐述。
图4为本发明状态信息获取方法实施例四的信令图。本实施例适用于LTE网络、2G/3G网络与传统的智能网共存的状态下，SCP需要获取用户设备的状态信息的场景。具体的，本实施例包括如下步骤：
401、SCP向HSS发送ATI请求。
本步骤中，SCP在需要获取用户设备状态信息的时候，向HSS发送ATI请求，请求获取用户设备在2G/3G网络中的状态信息。
402、HSS进行T-ADS确定用户设备的接入域。
403、HSS向MME发送插入用户数据请求。
HSS向用户设备注册的MME发送插入用户数据请求(Insert Subscriber Data Request，IDR)，以查询用户设备的T-ADS信息。
404、MME向HSS发送插入用户数据应答。
MME向HSS发送插入用户数据应答(Insert Subscriber Data Answer，IDA)，该UDA携带用户设备的T-ADS信息。
405、HSS向SGSN发送PSI。
HSS向用户设备注册的SGSN发送PSI消息以查询用户设备的T-ADS信息。
406、SGSN向HSS发送PSI响应。
SGSN向HSS发送PSI响应(PSI ACK)，该PSI ACK携带用户设备的T-ADS信息。
407、HSS确定用户设备处于LTE网络。
本步骤中，HSS综合从MME以及SGSN获取到的用户设备的T-ADS信息确定用户设备所处的接入域。若HSS确定出用户设备处于2G/3G网络(图中未示出)，则采用现有技术获取用户设备的状态信息；若HSS确定出用户设备处于LTE网络，则执行步骤408。
408、HSS向TAS发送IDR。
本步骤中，HSS向用户设备注册的TAS发送IDR以获取用户设备的状态信息。
409、TAS向HSS发送IDA。
TAS在查询到用户设备的呼叫状态后，将状态信息携带在IDA中发送给HSS。

图5为本发明状态信息获取方法实施例五的信令图。本实施例适用于LTE网络、2G/3G网络与传统的智能网共存的状态下，用户设备的状态信息发生了更新，SCP需要获取用户设备的状态信息的场景。具体的，本实施例包括如下步骤：
501、TAS确定用户设备的呼叫状态改变。
本步骤中，TAS判断用户设备的呼叫状态是否发生了改变，例如，呼叫状态从忙碌变为空闲等，若未发生改变，则TAS继续监测用户设备的呼叫状态；否则，若发生变化，则执行步骤502。
502、TAS向HSS发送PUR。
对于某一个具体的用户设备，若TAS监测出该用户设备的呼叫状态发生了变化，则向HSS发送PUR。
需要说明的是，由于TAS同时可能会监测多个用户设备的状态信息，因此，可以对每个用户设备设置标识，发送PRU时携带对应用户设备的标识，使得后 续HSS，可根据用户设备的标识，只有在接收到具有相同标识的ATI请求后，才向SCP发送更新的标识。
503、HSS向TAS发送PUA。
本步骤中，HSS保存用户设备更新了的状态信息并向TAS发送PUA。
504、SCP向HSS发送ATI请求。
本步骤中，SCP在需要获取用户设备状态信息的时候，向HSS发送ATI请求，请求获取用户设备在2G/3G网络中的状态信息。
505、HSS进行T-ADS确定用户设备的接入域。
506、HSS向MME发送IDR。
HSS向用户设备注册的MME发送IDR，以查询用户设备的T-ADS信息。
507、MME向HSS发送IDA。
MME向HSS发送IDA，该UDA携带用户设备的T-ADS信息。
508、HSS向SGSN发送PSI。
HSS向用户设备注册的SGSN发送PSI消息以查询用户设备的T-ADS信息。
509、SGSN向HSS发送PSI响应。
SGSN向HSS发送PSI响应(PSI ACK)，该PSI ACK携带用户设备的T-ADS信息。
510、HSS确定用户设备处于LTE网络。
本步骤中，HSS综合从MME以及SGSN获取到的用户设备的T-ADS信息确定用户设备所处的接入域。具体的，若HSS确定出用户设备处于2G/3G网络(图中未示出)，则采用现有技术获取用户设备的状态信息；否则，若HSS确定出用户设备处于LTE网络，则执行步骤408。
511、HSS向SCP发送ATI响应。
HSS在接收到IDA后，直接查询用户设备的状态信息，然后将用户设备的状态信息携带在ATI响应中发送给SCP。
上述步骤502中的PUR与步骤503中的PUA可根据需求设置。例如，在3GPP2938基础上，PUR与PUA的参数设置格式具体如表4和表6。
