Abstract

本发明公开了一种业务访问的方法、设备、系统及存储介质。一种业务访问的方法包括：网络侧设备向UE发送消息，所述消息中包含IMS网络是否支持Ut接口的指示。用户设备接收网络侧设备发送的消息，所述消息中包含IMS网络是否支持Ut接口的指示；所述用户设备根据所述消息判断是否发起Ut接口连接。本发明在UE发起Ut接口连接之前，通过网络侧设备通知UE，告知所连接的IMS网络是否支持Ut接口，避免出现UE发起Ut接口连接请求后，因IMS网络不支持Ut接口而导致请求失败的情况。

Description

业务访问的方法、设备、系统及存储介质 技术领域
本发明属于通信领域，尤其涉及一种业务访问的方法、设备、系统及存储介质。
背景技术
Ut接口是IMS(IP Multimedia Subsystem，互联网协议多媒体子系统)提供的终端补充业务配置接口。终端使用IMS网络，通过UE(User Equipment，用户设备)与AS(Application Server,应用服务器)之间的Ut接口，完成如下功能：号码显示、呼叫前转和呼叫限制等补充业务的数据配置。TS24.623协议中定义了Ut接口，使用IETF RFC4825定义的XCAP(XML Configuration Access Protocol，XML配置访问协议)协议，UE作为客户端client，AS作为服务器端Server，使用HTTP(HyperText Transfer Protocol，超文本传输协议)的PUT,DELETE,GET方法来管理AS上保存的XML(Extensible Markup Language，可扩展标记语言)格式的业务数据。
由于Ut接口是可选接口，某些IMS网络中未部署。目前，用户是不知道当前接入的IMS网络是否支持Ut接口的，当用户需要做号码显示、呼叫前转和呼叫限制等数据配置的时候，会在UE上发起相关的请求，此时如果IMS网络没有部署Ut接口，UE无法与AS建立Ut接口，该请求失败。
发明内容

具体实施方式
下面通过实施例的方式进一步说明本发明，但并不因此将本发明限制在所述的实施例范围之中。
实施例1
如图1所示，本实施例提供了一种业务访问的方法，其包括：
步骤11：网络侧设备向UE发送消息，消息中包含IMS网络是否支持Ut接口的指示。
该方法中，网络侧设备通过发送的消息通知UE IMS网络是否支持Ut接口，可便于UE判断是否发起Ut接口连接，避免出现UE发起Ut接口连接请求后，因IMS网络不支持Ut接口而导致请求失败的情况。
如图2所示，本实施例还提供了一种业务访问的方法，包括：
步骤21：UE接收网络侧设备发送的消息，消息中包含IMS网络是否支持Ut接口的指示。
步骤22：UE根据消息判断是否发起Ut接口连接。其中，若消息指示IMS网络支持Ut接口，则UE发起Ut接口连接，若消息指示IMS网络不支持Ut接口，则UE不发起Ut接口连接。
该方法中，UE通过接收的消息获知IMS网络是否支持Ut接口，从而判 断是否发起Ut接口连接，避免出现UE发起Ut接口连接请求后，因IMS网络不支持Ut接口而导致请求失败的情况。
实施例2
本实施例是对实施例1的进一步限定。本实施例的一种业务访问的方法中，网络侧设备可以包括P-CSCF(Proxy-Call Session Control Funtion，代理呼叫会话控制功能)服务器，即可以实现由P-CSCF服务器通知UE IMS网络是否支持Ut接口。具体地，步骤11可以具体包括：P-CSCF服务器向UE发送响应于UE发起的IMS注册请求的注册回复消息。注册回复消息中包含第一指示信息，第一指示信息用于指示当前IMS网络是否支持Ut接口。当然除了第一指示信息以外，注册回复消息还可以包括现有注册回复消息的相关信息。
其中，P-CSCF服务器可以根据本地配置的Ut信息确定第一指示信息指示当前IMS网络支持Ut接口或不支持Ut接口。
进一步地，当第一指示信息指示当前IMS网络支持Ut接口时，第一指示信息还可以包括支持Ut接口的位置信息，如TA/TA列表(Tracking Area,跟踪区域)。位置信息可以便于UE进一步判断当前所处位置是否在位置信息的范围内，若是，则第一指示信息有效，UE可以发起Ut接口连接。
当网络侧设备包括P-CSCF服务器时，步骤21可以具体包括：UE接收P-CSCF服务器发送的响应于UE发起的IMS注册请求的注册回复消息，注册回复消息中包含第一指示信息，第一指示信息用于指示当前IMS网络是否支持Ut接口。
进一步地，当第一指示信息指示当前IMS网络支持Ut接口且还包括支持Ut接口的位置信息时，步骤22可以具体包括UE判断当前所处位置是否在位置信息的范围内，若是，则第一指示信息有效，UE发起Ut接口连接。
本实施例的方法可以在IMS注册过程中，通过P-CSCF服务器在注册回复消息中将“IMS网络是否支持Ut接口”通知UE。相应地，还通过UE接收P-CSCF服务器的注册回复消息获知“IMS网络是否支持Ut接口”。
图3示出了UE进行IMS注册的完整过程。其包括：
步骤31：UE选择无线网络，发起无线连接，其中携带注册请求；
步骤32：无线接入网将上述注册请求转发给核心网服务器，UE向核心网 服务器发起注册接入；核心网服务器完成注册接入，允许UE接入该无线网络，将注册接入完成消息发给无线接入网；
步骤33：无线接入网将上述注册完成消息转发给UE，完成UE的接入和注册流程；
步骤34：UE向P-CSCF服务器发起IMS注册请求；
步骤35：P-CSCF服务器对UE进行鉴权认证后，结合本地配置的Ut信息，将注册回复消息发给UE，注册回复消息中包含第一指示信息，指示当前IMS网络是否支持Ut接口，如果支持，第一指示信息还包括支持Ut接口的位置信息，如TA/TA列表；
步骤36：UE根据收到的注册回复消息，判断IMS网络是否支持Ut接口，如果支持，进一步判断UE当前所处位置是否在位置信息的范围内，若是，则第一指示信息有效，UE发起Ut接口连接，开始Ut接口上的补充业务数据配置流程，否则，UE不发起Ut接口连接。
实施例3
本实施例是对实施例1的进一步限定。本实施例的一种业务访问的方法中，网络侧设备可以包括核心网服务器，即可以实现由核心网服务器通知UE IMS网络是否支持Ut接口。具体地，步骤11可以具体包括：核心网服务器通过无线接入网向UE发送响应于UE发起的核心网注册接入请求的注册接入回复消息，注册接入回复消息中包含携带第二指示信息的IMS-APN，第二指示信息用于指示当前IMS网络是否支持Ut接口。其中，注册接入回复消息可以包括Attach Accept(附着接纳)或TAU Accept(跟踪区更新接纳)。指示当前IMS网络支持Ut接口的IMS-APN可以表示为Ut.IMS-APN。
进一步地，当第二指示信息指示当前IMS网络支持Ut接口时，第二指示信息还包括支持Ut接口的位置信息，如TA/TA列表。位置信息可以便于UE进一步判断当前所处位置是否在位置信息的范围内，若是，则第二指示信息有效，UE可以发起Ut接口连接。
当网络侧设备包括核心网服务器时，步骤21可以包括：UE通过无线接入网接收核心网服务器发送的响应于UE发起的核心网注册接入请求的注册接入回复消息，注册回复消息中包含携带第二指示信息的IMS-APN，第二指示信 息用于指示当前IMS网络是否支持Ut接口。其中，注册接入回复消息可以包括Attach Accept(附着接纳)或TAU Accept(跟踪区更新接纳)。指示当前IMS网络支持Ut接口的IMS-APN可以表示为Ut.IMS-APN。
进一步地，当第二指示信息指示当前IMS网络支持Ut接口且还包括支持Ut接口的位置信息时，步骤22可以包括UE判断当前所处位置是否在位置信息的范围内，若是，则第二指示信息有效，UE发起Ut接口连接。
本实施例的方法可以通过核心网服务器对IMS-APN配置第二指示信息将“IMS网络是否支持Ut接口”通知UE。相应地，还通过UE接收核心网服务器对IMS-APN配置的第二指示信息获知“IMS网络是否支持Ut接口”。
图4示出了UE进行IMS注册的完整过程。其包括：
步骤41：UE选择无线网络，发起无线连接，其中携带注册请求；
步骤42：无线接入网将上述注册请求转发给核心网服务器，核心网在注册接入回复消息中包含携带第二指示信息的IMS-APN，第二指示信息用于指示当前IMS网络是否支持Ut接口，如果支持，第二指示信息还包括支持Ut接口的位置信息，如TA/TA列表；
步骤43：核心网将上述的IMS-APN通过无线接入网，在“完成接入和注册”消息中发给UE；
步骤44：UE向P-CSCF服务器发起IMS注册请求；
步骤45：P-CSCF对UE进行鉴权认证后，回复注册成功消息；
步骤46：UE根据步骤43中收到的IMS-APN携带的第二指示信息，判断IMS网络是否支持Ut接口，如果支持，进一步判断UE当前所处位置是否在位置信息的范围内，若是，则第一指示信息有效，UE发起Ut接口连接，开始Ut接口上的补充业务数据配置流程，否则，UE不发起Ut接口连接。

进一步地，当第一指示信息指示当前IMS网络支持Ut接口时，第一指示信息还包括支持Ut接口的位置信息。
在另一种可选方式中，网络侧设备为核心网服务器。发送模块51用于通过无线接入网向UE发送响应于UE发起的核心网注册接入请求的注册接入回复消息，注册接入回复消息中包含携带第二指示信息的IMS-APN，第二指示信息用于指示当前IMS网络是否支持Ut接口。
进一步地，当第二指示信息指示当前IMS网络支持Ut接口时，第二指示信息还包括支持Ut接口的位置信息。

进一步地，当第一指示信息指示当前IMS网络支持Ut接口且还包括支持Ut接口的位置信息时，判断模块用于判断当前所处位置是否在位置信息的范围内，若是，则发起Ut接口连接。
在另一种可选方式中，当网络侧设备包括核心网服务器时，接收模块61用于通过无线接入网接收核心网服务器发送的响应于UE发起的核心网注册接入请求的注册回复消息，注册回复消息中包含携带第二指示信息的IMS-APN，第二指示信息用于指示当前IMS网络是否支持Ut接口。
