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作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。
本发明的技术方案，可以应用于能够通过电路域网络和分组域网络完成通信的各种通信***，例如：IP多媒体子***(IMS，Internet Protocol Multimedia Subsystem)，图1示出了适用本发明的故障处理的方法的通信***的示意性结构图，如图1所示，该通信***可以包括接入网、IP多媒体子***(IMS，IP Multimedia subsystem)和外部网络三部分。
其中，作为外部网络，可以列举为用户提供业务服务的各种网络，例如，互联网(Internet)、公共交换电话网络(PSTN，Public Switched Telephone Network)等。
接入网络可以包括电路交换(CS，Circuit Switch)域或分组交换(PS， Packet Switched)域。
具体地，接入网络可以是全球移动通讯***(GSM，Global System of Mobile communication)，码分多址(CDMA，Code Division Multiple Access)网络，宽带码分多址(WCDMA，Wideband Code Division Multiple Access Wireless)网络，通用分组无线业务(GPRS，General Packet Radio Service)网络，长期演进(LTE，Long Term Evolution)网络，无线局域网络(WLAN，Wireless Local Area Networks)等。
随着技术的发展，在例如VoLTE等技术中，已经能够在PS域实现语音传输，VoLTE是一种IP数据传输技术，无需2G/3G网，全部业务承载于4G网络上。换言之，4G网络下不仅仅提供高速率的数据业务，同时还提供高质量的音视频通话，后者便需要VoLTE技术来实现。
IMS(或者，也可以称为核心网络)用于将来自接入网络的数据传输至外部网络，或者，将外部网络的数据传输至接入网络，更具体地，IMS是在基于IP的网络上提供多媒体业务的通用网络架构。
用户设备(UE，User Equipment)通过接入网络接入到IMS。UE包括移动终端(Mobile Terminal)、或固定终端。移动终端可以是移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，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，它们与无线接入网交换语言和/或数据。
以下，为了便于理解和说明，以适用于IMS时的处理过程为例，对本发明实施例的故障处理的方法和装置进行说明。
图2示出了从第二服务集中化和连续性应用服务器角度描述的，本发明实施例的故障处理的方法100的示意性流程图，如图2所示，该方法100包括：
S110，在第一服务集中化和连续性应用服务器SCC AS故障后，第二SCC AS接收归属用户服务器HSS发送的用户设备所接入的接入转发控制功能ATCF设备的标识，该第二SCC AS是呼叫会话控制功能CSCF设备在检测到该第一SCC AS故障后确定的；
S120，该第二SCC AS根据该ATCF设备的标识，向该ATCF设备发送该第二SCC AS的标识。
S130，该第二SCC AS接收该ATCF设备根据该第二SCC AS的标识发送的切换请求。
首先，对上述方法100涉及的IMS中的网元进行说明。
A.归属用户服务器(HSS，Home Subscriber Server)
HSS是归属网络中存储用户签约信息以及业务签约信息等的集中综合数据库，位于IMS架构的最顶层，HSS包含在处理媒体会话时所需的用户相关签约数据，例如，位置信息、安全信息(包括鉴权和授权信息)、用户业务属性信息(包括用户的签约业务信息)，以及分配给用户的服务CSCF(S-CSCF)信息，用户标识(包括公共及私有标识)、号码和地址信息等。
B.服务集中化和连续性应用服务器(SCC AS，Service Centralization and Continuity Application Server)
SCC AS可以作为用户设备的会话发起协议应用服务器(SIP AS，Session Initiation Protocal)，将用户设备(通过接入网络)接入IMS，完成IMS会话建立和控制，它是归属网络中的IMS应用服务器，是主叫路径的第一个AS，被叫路径的最后一个AS。作为终呼接入时，可以根据接入网情况、用户设备的能力(例如，是否支持VoLTE)、IMS注册情况、CS状态和运营商策略等因素进行，选择是用户设备通过CS域或PS域进行通信。
并且，当用户设备需要进行域切换时，例如，在用户设备支持VoLTE和传输CS域语音传输的情况下，例如，当用户设备2G/3G网络从移动至4G网络时，或者，当用户设备从4G网络移动至2G/3G网络时，SCC AS执行切换处理，例如，增强单待语音连续(eSRVCC，enhanced single radio voice call continuity)切换处理，为用户设备提供切换服务，以确保语音业务的连续性。
C.呼叫会话控制功能(CSCF，Call Session Control Function)设备
CSCF设备是IMS内部的功能实体，是整个IMS的核心。主要负责处理多媒体呼叫会话过程中的信令控制。它管理IMS的用户鉴权、IMS承载面服务质量(QoS，Quality of Service)、与其它网元配合进行SIP会话的控制，以及业务协商和资源分配等。
CSCF根据功能分为代理CSCF(P-CSCF，Proxy CSCF)，查询CSCF (I-CSCF，Interrogating CSCF)，服务CSCF(S-CSCF，Serving CSCF)等。
其中，P-CSCF是IMS拜访网络(接入网络的一例)的统一入口点。所有发起于用户设备和终止于用户设备的会话消息都要通过P-CSCF。P-CSCF作为一个SIP Proxy，负责与接入网络相关的用户鉴权与互联网安全协定(IPSec，Internet Protocol Security)管理，网络防攻击与安全保护，为节约无线网络资源进行SIP信令压缩与解压，用户的漫游控制，通过策略决策功能(PDF，Policy Decision Function)进行承载面的网络地址转换(NAT，Network Address Translation)与QoS等功能等。例如，P-CSCF可以根据用户设备提供的域名决定I-CSCF，并向该I-CSCF转发来自用户设备的SIP注册请求。再例如，P-CSCF可以向在用户设备发起注册流程时确定S-CSCF转发来自该用户设备的SIP消息。
I-CSCF是IMS归属网络(接入网络的另一例)的入口点。在注册过程中，I-CSCF通过查询HSS，为用户选择一个S-CSCF。在呼叫过程中，去往IMS网络的呼叫首先路由到I-CSCF，由I-CSCF从HSS获取用户所注册的S-CSCF地址，将消息路由到S-CSCF。例如，I-CSCF可以为用户设备指定某个S-CSCF来执行SIP注册。再例如，I-CSCF可以从HSS中获取S-CSCF的地址，转发SIP请求，或者将其他网络传来的SIP请求路由到S-CSCF。
S-CSCF在IMS网络会话控制中处于核心地位，它接受来自拜访网络通过P-CSCF转发来的注册请求，与HSS配合进行用户鉴权。并从HSS处下载用户签约的业务数据。S-CSCF对于用户主叫及被叫侧进行路由管理，根据用户签约的初始过滤规则(IFC：Initial Filter Criteria)，进行SIP AS触发，实现丰富的IMS业务功能。例如，S-CSCF可以在接收注册请求后，通过HSS使注册请求生效。再例如，S-CSCF可以控制已注册的会话终端，可作为代理服务器(Proxy-Server)。再例如，S-CSCF可以在接收请求后，进行内部处理或转发，也可作为用户代理(UA，User Agent)，中断或发起SIP事务。再例如，S-CSCF还可以与业务平台进行交互，提供多媒体业务。
需要说明的是，上述P-CSCF、S-CSCF、I-CSCF可以独立配置于不同实体，也可以集成于同一实体，以下，为了便于理解和说明，统称为CSCF设备。
D.接入切换控制功能(ATCF，Access Transfer Control Function)设备
ATCF设备配置于拜访网络，用于控制接入网关(AGW，Access Gateway)，以锚定用户在拜访网络发起的语音会话，具体地说，ATCF可以锚定用户语音会话的信令部分，并控制AGW锚定该会话的媒体部分。
在进行用于使用户设备在2G/3G网络与4G网络(例如，LTE网络)之间的切换处理，例如，上述eSRVCC切换处理时，拜访网络的移动交换中心(MSC，Mobile Switching Center)服务器不再与用户归属IMS网络重建会话接入端、与远端重建媒体，而是与拜访网络的锚定ATCF重建会话(包括媒体)，以避免用户所访问的语音业务发生中断，改善用户体验。
需要说明的是，ATCF设备和P-CSCF设备均属于拜访网络，可以配置于同一实体也可以配置于不同实体，并且，ATCF设备和P-CSCF设备之间能够互相通信以交互用户设备的相关信息，例如，用户标识等。
下面结合具体交互流程，对上述各网元在本发明实施例的方法100中的动作和功能进行详细说明。
图3是根据本发明的故障处理的方法的示意***互图。
如图3所示，在S201，执行针对UE#1(即，用户设备的一例)的注册流程。
作为示例而非限定，在该注册流程中，P-CSCF设备(或者，ATCF设备)在接收到UE#1发送的注册请求消息后，将该注册请求消息和用于指示UE#1所接入的ATCF设备(以下，为了便于区分，记做ATCF设备#1)的标识(即，ATCF设备的标识的一例)发送至S-CSCF设备。
S-CSCF设备为该UE#1分配一个SCC AS(即，第一SCC AS，以下为了便于理解和区分，记做SCC AS#1)，并将该注册请求消息和该ATCF设备#1的标识传输至该SCC AS#1。
从而，SCC AS#1能够获取ATCF设备的标识。
并且，作为ATCF设备的标识，可以列举以下任意信息：
可选地，该ATCF设备的标识包括该ATCF设备的公共业务标识PSI和该ATCF设备的路径通用资源标识符Path URI。
具体地说，通过公共业务标识(PSI，Public Service Identity)和该ATCF 设备的路径通用资源标识符(Path URI，Path Uniform Resource Identifier)能够唯一地标识一个ATCF设备，因此，上述ATCF设备的标识可以包括该PSI和该Path URI。
应理解，以上列举的ATCF设备的标识仅为示例性说明，本发明并不限定于此，例如，P-CSCF设备在接收到UE#1发送的注册请求时为该UE#1分配用于单待语音连续的会话转换号码(STN-SR，Session Transfer Number for SRVCC)，在该STN-SR可以用于标识该UE#1所接入的ATCF设备(即，ATCF设备#1)的情况下，还可以将该STN-SR作为上述ATCF设备的标识。
另外，上述ATCF设备#1的标识可以携带于P-CSCF设备向S-CSCF设备转发的上述注册请求消息中，并且，S-CSCF设备可以将携带有ATCF设备#1的标识的注册请求消息转发给该SCC AS#1，从而SCC AS#1可以从该注册请求消息中获取ATCF设备#1的标识。
在S202，SCC AS#1可以将该ATCF设备#1的标识发送至HSS。
例如，SCC AS#1可以将ATCF设备#1的标识作为透明数据，通过透明数据更新请求(PUR，Profile Update Request)消息推送至HSS。从而，能够利用现有的信令实现ATCF设备的标识的传输。
应理解，以上列举的HSS获取ATCF设备的标识的过程仅为示例性说明，本发明并未限定于此，例如，SCC AS#1还可以通过其他信令将ATCF设备的标识传输至至HSS，或者，SCC AS#1还可以经由CSCF设备将ATCF设备的标识传输至HSS。
在HSS可以存储与该SCC AS#1相对应的ATCF设备#1的标识。
在本发明实施例中，S-CSCF设备可以检测SCC AS#1的运行状态，当检测到SCC AS#1故障后，可以重新选择一个SCC AS(即，第二SCC AS，以下为了便于理解和区分，记做SCC AS#2)，使该SCC AS#2替代SCC AS#1，用于执行针对UE#1的切换处理，例如，上述eSRVCC切换处理。
在S203，HSS可以采用以下任一方式将ATCF设备#1的标识传输至SCC AS#2。
方式1
可选地，在第二SCC AS接收HSS发送的用户设备所接入的ATCF设 备的标识之前，该方法还包括：

则，该第二SCC AS接收HSS发送的用户设备所接入的ATCF设备的标识，包括：
该第二SCC AS接收该HSS发送的用户设备所接入的ATCF设备的标识，其中，该ATCF设备的标识是该HSS在根据该用户标识以及该用户标识与该ATCF设备之间的映射关系信息确定该ATCF设备之后发送的。
具体地说，此情况下，HSS可以记录该SCC AS#1相对应的ATCF设备(即，ATCF设备#1)的标识与该UE#1的用户标识之间的映射关系。
CSCF设备(具体地说，是I-CSCF设备)在确定SCC AS#2之后，可以通过***信令(例如，用户数据读取请求UDR消息)将该UE#1的标识传输至SCC AS#2，作为示例而非限定，该UE#1的标识可以列举例如，UE#1的移动用户手机号MSISDN、UE#1的国际移动用户标识IMSI、UE#1的国际移动台设备标识IMEI、UE#1的IP地址等。
SCC AS#2可以根据该UE#1的标识判定本地未存储UE#1的用户数据，从而可以向HSS发起请求获取用户数据的流程。并且，SCC AS#2可以将该UE#1的标识传输至HSS，以使HSS根据该UE#1的标识，查找UE#1所接入的ATCF设备，即，ATCF设备#1。
并且，通过利用用户数据读取请求(UDR，User Data Request)消息携带上述用户标识，能够利用现有的信令实现用户标识的传输。
应理解，以上列举的通过UDR消息携带用户标识的方式仅为示例性说明，本发明并不限定于此，其他能够实现HSS与SCC AS之间信令传输的消息均落入本发明的保护范围内。
HSS在接收到携带有UE#1的标识的消息后，可以根据UE#1的标识，查找预先记录的用户标识与ATCF设备的标识之间的映射关系，从而，能够查找到UE#1所接入的ATCF设备，即，ATCF设备#1。
并且，HSS在如上所述确定ATCF设备#1之后，可以将该ATCF设备#1的标识和UE#1的用户数据传输至SCC AS#2。
另外，通过利用用户数据读取响应(UDA，User Data Answer)消息 携带ATCF设备#1的标识，能够利用现有的信令实现ATCF设备的标识的传输。
应理解，以上列举的通过UDA消息携带ATCF设备#1的标识的方式仅为示例性说明，本发明并不限定于此，其他能够实现HSS与SCC AS之间信令传输的消息均落入本发明的保护范围内。
通过本发明实施例的故障处理的方法，HSS能够将用户数据与ATCF设备的标识同时传输至SCC AS#2，能够减少交互流程，节约***资源开销。
需要说明的是，在本发明实施例中，上述用户数据可以是现有技术中用于进行例如，eSRVCC切换处理的信息，这里，为了避免赘述，省略其详细说明。
方式2
可选地，在第二SCC AS接收HSS发送的用户设备所接入的ATCF设备的标识之前，该方法还包括：
该第二SCC AS向该HSS发送UDR消息，该UDR消息包括该第一SCC AS的标识；
则，该第二SCC AS接收HSS发送的用户设备所接入的ATCF设备的标识，包括：
该第二SCC AS接收该HSS发送的用户设备所接入的ATCF设备的标识，其中，该ATCF设备的标识是该HSS在根据该第一SCC AS的标识以及该第一SCC AS的标识与该ATCF设备之间的映射关系信息确定该ATCF设备之后发送的。
具体地说，此情况下，HSS可以记录该SCC AS#1相对应的ATCF设备(即，ATCF设备#1)的标识与SCC AS#1的标识之间的映射关系。
CSCF设备(具体地说，是I-CSCF设备)在确定SCC AS#2之后，可以通过***信令(例如，用户数据读取请求UDR消息)将SCC AS#1的标识传输至SCC AS#2，作为示例而非限定，该SCC AS#1的标识可以列举例如，SCC AS#1的会话转移标识ATU-STI等。
SCC AS#2可以向HSS发起请求获取SCC AS#1所对应的用户设备(包括上述UE#1)的用户数据的流程。并且，SCC AS#2可以将SCC AS#1的 标识传输至HSS，以使HSS根据SCC AS#1的标识，查找SCC AS#1所对应的ATCF设备，即，ATCF设备#1。
并且，通过利用用户数据读取请求(UDR，User Data Request)消息携带上述SCC AS#1的标识，能够利用现有的信令实现用户标识的传输。
应理解，以上列举的通过UDR消息携带SCC AS的标识的方式仅为示例性说明，本发明并不限定于此，其他能够实现HSS与SCC AS之间信令传输的消息均落入本发明的保护范围内。
HSS在接收到携带有SCC AS#1的标识的消息后，可以根据SCC AS#1的标识，查找预先记录的SCC AS的标识与ATCF设备的标识之间的映射关系，从而，能够查找到SCC AS#1所对应的(包括UE#1所接入的)ATCF设备，即，ATCF设备#1。
并且，HSS在如上所述确定ATCF设备#1之后，可以将该ATCF设备#1的标识传输至SCC AS#2。
另外，通过利用用户数据读取响应(UDA，User Data Answer)消息携带ATCF设备#1的标识，能够利用现有的信令实现ATCF设备的标识的传输。
应理解，以上列举的通过UDA消息携带ATCF设备#1的标识的方式仅为示例性说明，本发明并不限定于此，其他能够实现HSS与SCC AS之间信令传输的消息均落入本发明的保护范围内。
通过本发明实施例的故障处理的方法，HSS能够将用户数据与ATCF设备的标识同时传输至SCC AS#2，能够减少交互流程，节约***资源开销。
方式3
CSCF设备(具体的说，是I-CSCF设备)在确定SCC AS#2之后，可以通过***信令通知HSS：该SCC AS#2替代SCC AS#1。
其后，HSS在接收到该通知后，可以查找SCC AS#1所服务的用户设备(包括UE#1)，获取各用户设备的用户数据以及所接入的ATCF设备，即，ATCF设备#1，并该根据SCC AS#2的标识通过***信令主动地将各用户设备与各ATCF设备的对应关系以及各用户设备的用户数据发送至CSCF设备，并且，CSCF设备可以将ATCF设备#1的标识传输至SCC AS#2。
需要说明的是，在方式3中，HSS查找SCC AS#1所对应ATCF设备的方法可以与上述方式1或方式2中的方法相似，即，可以利用SCC AS#1的标识进行查找，也可以利用UE#1的用户标识进行查找，这里，为了避免赘述省略其详细说明。
从而，SCC AS#2能够获取ATCF设备#1的标识。
在S204，SCC AS#2可以根据ATCF设备#1的标识，将SCC AS#2的标识，例如，通过CSCF设备(具体地说，是I-CSCF设备)发送至从而ATCF设备#1。这里，信息从SCC AS路由至ATCF设备的方法和过程可以与现有技术相似，这里，为了避免赘述，省略其详细说明。
可选地，该第二SCC AS的标识包括该第二SCC AS的会话转移标识ATU-STI。
具体地说，通过会话转移标识(ATU-STI，Access Transfer Update-Session Transfer Identifier)能够唯一地标识一个SCC AS，因此，上述第二SCC AS的标识可以包括第二SCC AS的ATU-STI。
应理解，以上列举的第二SCC AS的标识的示例仅为示例性说明，本发明并不限定于此，其他能够用于唯一地指示一个SCC AS的信息均落入本发明的保护范围内。
