Technical field

本发明涉及无线通信技术，尤其涉及一种在电路域接入终端与 AS之间交互控制信息的方法及设备。背景技术 The present invention relates to wireless communication technologies, and in particular, to a method and device for interactive control information between a circuit domain access terminal and an AS. Background technique

移动终端通过码分多址（ Code Division Multiple Access , CDMA )、全球移动通讯*** ( Global System for Mobile Communications , GSM )等无线网络接入网络的方式有两种：电路域方式、数据域方式。通常，通过电路域方式接入网络为用户提供电路域业务，比如语音呼叫、短消息；通过数据域接入网络为用户提供数据域业务，比如上网。 There are two ways for a mobile terminal to access a network through a wireless network such as Code Division Multiple Access (CDMA) or Global System for Mobile Communications (GSM): circuit domain mode and data domain mode. Generally, the circuit domain access network provides users with circuit domain services, such as voice calls and short messages. The data domain access network provides users with data domain services, such as Internet access.

随着无线网络的发展，数据域的接入能力不断提升，通过数据域也可以为用户提供实时性要求较高的语音呼叫业务。为此，在网络中引入互联网协议多媒体子***（ IP Multimedia Subsystem, IMS ) , 为用户提供 VOIP业务。应用服务器（ Application Server , AS )是 IMS中的业务实体，为用户提供各种丰富的业务体验。 IMS基于用户通过数据域方式接入网络，采用会话初始协议（Session Initiation Protocol, SIP )信令。为了顺应通信融合趋势， IMS 不仅可以为通过数据域接入的终端提供服务，而且对于通过电路域接入的用户，也可以把呼叫锚定到 IMS , 由 IMS的 AS为用户提供业务。因此 IMS可以为采用数据域接入的用户提供业务，也可以为电路域接入的用户提供业务。 With the development of the wireless network, the access capability of the data domain is continuously improved, and the voice call service with higher real-time requirements can also be provided to the user through the data domain. To this end, the Internet Protocol Multimedia Subsystem (IMS) is introduced into the network to provide users with VOIP services. The Application Server (AS) is a business entity in IMS that provides users with a variety of business experiences. The IMS accesses the network through the data domain, and uses Session Initiation Protocol (SIP) signaling. In order to comply with the trend of communication convergence, IMS can not only provide services for terminals accessing through the data domain, but also for users accessing through the circuit domain, the call can be anchored to the IMS, and the AS of the IMS can provide services for the user. Therefore, IMS can provide services for users who use data domain access, and can also provide services for users accessing the circuit domain.

通过电路域接入 IMS的用户包括：不支持 SIP信令的传统终端及支持 SIP 信令的终端。这两类终端在传统电路域网络覆盖范围，通过电路域方式接入网络。为了描述方便，本文把上述两类通过电路域接入的终端通称为电路域接入终端。 The users accessing the IMS through the circuit domain include: a legacy terminal that does not support SIP signaling and a terminal that supports SIP signaling. These two types of terminals are connected in the circuit domain by traditional circuit domain network coverage. The internet. For convenience of description, the above two types of terminals accessed through the circuit domain are generally referred to as circuit domain access terminals.

电路域接入终端把呼叫锚定到 IMS提供业务，一般采用智能改号锚定方式。以 CDMA主叫为例，用户通过电路域发起呼叫，端局移动交换中心（ Mobile Switch Center, MSC )收到用户的呼叫请求后，根据用户签约的智能触发器，发送 ORREQ消息到业务控制点（Service Control Point, SCP ) 。 SCP转发 ORREQ消息到 AS。 SCP向 MSC转发 AS返回的响应消息 orreq。 MSC对获取的 IMS呼叫路由号码进行号码分析，呼叫出局，通过 ISDN用户部分（ ISDN User Part, ISUP )信令发送初始地址消（ Initial Address Message, IAM )给媒体网关控制功能（ Media Gateway Control Function , MGCF )。 MGCF通过 SIP 信令发送携带有 IMS 呼叫路由号码的 INVITE给 I/S-CSCF, I/S-CSCF将 MGCF发送的 INVITE转发给 AS。 The circuit domain access terminal anchors the call to the IMS to provide services, and generally adopts an intelligent change anchoring mode. Taking the CDMA caller as an example, the user initiates a call through the circuit domain. After receiving the call request from the user, the mobile switching center (MSC) sends an ORREQ message to the service control point according to the smart trigger signed by the user ( Service Control Point, SCP). The SCP forwards the ORREQ message to the AS. The SCP forwards the response message orreq returned by the AS to the MSC. The MSC performs number analysis on the obtained IMS call routing number, and the call is sent out, and the Initial Address Message (IMM) is sent to the Media Gateway Control Function through the ISDN User Part (ISUP) signaling. MGCF). The MGCF sends the INVITE carrying the IMS call routing number to the I/S-CSCF through the SIP signaling, and the I/S-CSCF forwards the INVITE sent by the MGCF to the AS.

其中 MGCF是传统电路域核心网和 IMS间的接口实体，传统电路域核心网中各实体间如 MSC和 MGCF之间的呼叫建立消息一般采用 ISUP、电话用户部分（ Telephone User Part, TUP )等窄带中继。而通过窄带中继，无法象 SIP消息一样在终端和 AS间传递足够的信息，导致电路域接入终端无法把业务控制集中到 IMS进行。 The MGCF is an interface entity between the core network of the traditional circuit domain and the IMS. The call setup messages between the entities in the core network of the traditional circuit domain, such as the MSC and the MGCF, generally use narrowbands such as ISUP and Telephone User Part (TUP). relay. With narrowband relay, it is not possible to transfer sufficient information between the terminal and the AS as the SIP message, resulting in the circuit domain access terminal not being able to concentrate the traffic control to the IMS.

现有技术利用 GSM 的非结构化补充数据业务（ Unstructured Supplementary Service Data, USSD ) 实现电路域接入终端与 AS间的控制信令交互，以将电路域接入终端的业务控制集中到 IMS进行。其中， USSD是一种基于 GSM网络的新型实时交互式数据业务，它是在 GSM的短消息*** 技术基础上推出的一种新业务，与短信业务（ SMS )相似，承载在 GSM网络的信令信道上。 USSD又与 WAP业务相似，用于提供实时交互式数据业务。 The prior art utilizes GSM Unstructured Supplementary Service Data (USSD) to implement control signaling interaction between the circuit domain access terminal and the AS to concentrate the service control of the circuit domain access terminal to the IMS. Among them, USSD is a new real-time interactive data service based on GSM network. It is a new service based on GSM short message system technology. Similar to short message service (SMS), it carries signaling in GSM network. On the channel. USSD is similar to WAP services and is used to provide real-time interactive data services.

现有技术存在的缺陷在于： USSD 不能满足语音业务的实时性要求，且 CDMA没有 USSD, 也就无法实现电路域接入终端与 AS间的控制信令交互。发明内容 The disadvantages of the prior art are: The USSD cannot meet the real-time requirements of the voice service, and the CDMA does not have the USSD, and the control signaling interaction between the circuit domain access terminal and the AS cannot be realized.
