技术领域technical field

本发明涉及通信领域，特别是涉及一种在IMS网络中实现主叫彩像业务的方法以及装置。The invention relates to the communication field, in particular to a method and a device for realizing calling color image service in an IMS network.

背景技术Background technique

IMS(IP Multimedia Subsystem，IP多媒体子系统)采用分组域(PS)为其上层控制信令和媒体传输提供承载通道，使用SIP协议作为业务控制协议，利用SIP协议简单、易扩展、媒体组合方便的特点，通过分离业务控制与承载控制的方式，为用户提供了丰富的多媒体业务；IMS网络主要的功能实体包括控制用户注册、会话控制等功能的呼叫控制实体CSCF、提供各种业务逻辑控制功能的应用服务器AS、集中管理用户签约数据的归属用户服务器HSS以及用于实现与电路交换网互通的MGCF媒体网关控制功能/IM-MGW(IM-媒体网关)，用户通过当前所在地的代理呼叫会话控制实体P-CSCF接入IMS网络，会话和业务触发控制以及与AS的业务控制交互由用户注册地的归属服务呼叫会话控制实体S-CSCF完成。IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) adopts the packet domain (PS) to provide bearer channels for its upper layer control signaling and media transmission, uses the SIP protocol as the service control protocol, and uses the SIP protocol to be simple, easy to expand, and convenient for media combination It provides users with rich multimedia services by separating service control and bearer control; the main functional entities of the IMS network include the call control entity CSCF that controls functions such as user registration and session control, and the CSCF that provides various service logic control functions. Application server AS, home user server HSS for centralized management of user subscription data, and MGCF media gateway control function/IM-MGW (IM-media gateway) for realizing intercommunication with the circuit switching network. The user calls the session control entity through the agent at the current location The P-CSCF accesses the IMS network, and the session and service trigger control and the service control interaction with the AS are completed by the home service call session control entity S-CSCF where the user is registered.

主叫彩像业务是一种由主叫方登记和付费的多媒体业务，当主叫定制了该业务时，其呼叫的被叫在振铃的同时就会播放主叫定制的彩像，彩像包括图象、音乐、文字等各种多媒体信息。在IMS域，对于IP接入网络的用户终端，实现主叫彩像业务的方案有如下两种：Calling color video service is a multimedia service that is registered and paid for by the calling party. When the calling party subscribes to this service, the called party will play the color video customized by the calling party while ringing. Including images, music, text and other multimedia information. In the IMS domain, there are two schemes for implementing the calling chromatic image service for user terminals accessing the network via IP:

其一，对于支持HTTP下载的被叫终端，被叫用户通过HTTP下载的方式播放主叫彩像，具体步骤包括：First, for the called terminal that supports HTTP download, the called user plays the calling party's chromatic image through HTTP download, and the specific steps include:

步骤一、主叫用户存储其定制的彩像资源；Step 1, the calling user stores its customized chromatic image resources;

步骤二、主叫用户呼叫被叫时，主叫将存储彩像资源的地址发送给被叫，具体方式为：在请求消息中添加一个URL(Universal resource locator，统一资源定位符)，URL是一种以HTTP开头的地址信息)；Step 2, when the calling user calls the called party, the calling party sends the address of the stored chromatic image resource to the called party. The specific method is: add a URL (Universal resource locator, Uniform Resource Locator) in the request message, and the URL is a address information starting with HTTP);

步骤三、被叫根据接收到的地址从彩像资源存储处下载所述彩像；Step 3, the called party downloads the chromatic image from the chromatic image resource store according to the received address;

步骤四、在终端振铃的同时，被叫终端播放所述彩像；Step 4, while the terminal is ringing, the called terminal plays the chromatic image;

其二，对于支持早期媒体的终端，实现主叫彩像方案，参见图1，具体的流程描述如下：Second, for terminals that support early media, implement the calling chromatic image solution, see Figure 1, the specific process is described as follows:

步骤一、主叫用户(UE-A)发起呼叫请求(invite)，消息触发到MCIDAS(彩像业务服务器)，MCID AS不对信令进行特殊处理，将所述信令通过核心网路由到被叫UE-B；Step 1. The calling user (UE-A) initiates a call request (invite), and the message is triggered to MCIDAS (color image service server), and the MCID AS does not perform special processing on the signaling, and routes the signaling to the called party through the core network UE-B;

步骤二、被叫终端支持早期媒体，被叫终端完成媒体协商后，向主叫返回183响应，响应中携带标识，标识信息表示被叫终端支持早期媒体，响应中还包括媒体协商后的SDP(Session Initial Protocol，会话描述协议)信息；Step 2: The called terminal supports early media. After the called terminal completes media negotiation, it returns a 183 response to the calling party, carrying an identifier in the response. The identifier indicates that the called terminal supports early media, and the response also includes the SDP after media negotiation ( Session Initial Protocol, session description protocol) information;

步骤三、所述183响应到达MCID AS时，MCID AS向MRS(Media resourceserver，媒体资源服务器)发请求消息(invite)，MRS返回200响应，响应中的SDP携带MRS支持的媒体信息(MRS offer)；Step 3, when the 183 response arrives at the MCID AS, the MCID AS sends a request message (invite) to the MRS (Media resource server, media resource server), and the MRS returns a 200 response, and the SDP in the response carries the media information supported by the MRS (MRS offer) ;

步骤四、主叫接收到183响应后，向被叫发送PRACK响应信息，以确认收到了183响应，所述响应到达MCID AS时，MCID AS在响应中携带MCID AS在步骤三中接收到的MRS发送的媒体信息(MRS offer)；Step 4. After receiving the 183 response, the calling party sends a PRACK response message to the called party to confirm receipt of the 183 response. When the response reaches the MCID AS, the MCID AS carries the MRS received by the MCID AS instep 3 in the response Sent media information (MRS offer);

步骤五、被叫接收到PRACK响应信息，向主叫返回200响应，所述响应中携带早期媒体的协商结果；Step 5, the called party receives the PRACK response information, and returns a 200 response to the calling party, which carries the negotiation result of the early media;

步骤六、被叫向主叫返回180响应，当所述180响应到达MCID AS时，MCID AS发指示信息(info)给MRS，指示在被叫振铃时开始播放彩像；Step 6, the called party returns a 180 response to the calling party, and when the 180 response arrives at the MCID AS, the MCID AS sends instruction information (info) to the MRS, indicating that the chromatic image will be played when the called party rings;

步骤七、被叫振铃，同时MRS给被叫播放彩像。Step 7: The called party rings, and the MRS plays a chromatic image to the called party at the same time.

在CS域(电路域)，现有技术能提供主叫名片业务，但是该业务仅提供文本方式的名片，不能支持彩像。In the CS domain (circuit domain), the prior art can provide calling card services, but this service only provides text-based business cards and cannot support chromatic images.

对于通过非DTM(Dual Transfer Mode，双传递模式)无线接入网络接入的用户终端，不能同时共存PS业务和CS业务，并且CS业务优先于PS业务，只要所述终端上有CS业务，其PS业务就自动中断，因此，对于通过非DTM无线接入网络接入的用户终端做被叫时，无法实现主叫彩像业务。For a user terminal accessing through a non-DTM (Dual Transfer Mode, dual transfer mode) wireless access network, the PS service and the CS service cannot coexist at the same time, and the CS service has priority over the PS service. As long as the CS service is available on the terminal, its The PS service is automatically interrupted. Therefore, when a user terminal accessed through a non-DTM wireless access network is called, the color image service of the calling party cannot be realized.

具体实施方式Detailed ways

由于通过非DTM无线接入网络接入的终端，无法实现PS业务与CS业务的共存，为实现该类型用户终端做被叫时的主叫彩像业务，本发明实施例通过在发起CS呼叫之前，网络侧先与用户终端建立PS连接，向用户终端发送携带彩像信息的多媒体描述，终端根据所述描述获取彩像，并保存在本地，待彩像保存完毕后，网络侧再向终端发起CS呼叫请求，终端接收到CS呼叫请求后，在振铃同时，播放已经存储的彩像，从而解决了上述问题。Since the terminal accessed through the non-DTM wireless access network cannot realize the coexistence of the PS service and the CS service, in order to realize the calling chromatic image service when this type of user terminal is called, the embodiment of the present invention uses , the network side first establishes a PS connection with the user terminal, and sends a multimedia description carrying chromatic image information to the user terminal, and the terminal obtains the chromatic image according to the description and saves it locally. CS call request, after receiving the CS call request, the terminal plays the stored chromatic image while ringing, thus solving the above-mentioned problem.

网络侧发起与终端建立PS连接，终端获取彩像，需要终端保持PDP(PacketData Protocol，分组数据协议)上下文处于激活状态，The network side initiates the establishment of a PS connection with the terminal, and the terminal obtains the chromatic image. The terminal needs to keep the PDP (PacketData Protocol, packet data protocol) context active.

使PDP保持激活状态的方式有多种，优选的，终端发起重注册的方式可以实现PDP保持激活状态。There are many ways to keep the PDP activated. Preferably, the terminal initiates re-registration to keep the PDP activated.

参见图2，为本发明实施例的方法流程图，具体步骤描述如下：Referring to Fig. 2, it is a flow chart of the method of the embodiment of the present invention, and the specific steps are described as follows:

S201、终端在完成网络附着之后激活PDP上下文，所述终端为通过非DTM无线接入网络接入的终端；S201. The terminal activates a PDP context after completing network attachment, and the terminal is a terminal accessed through a non-DTM wireless access network;
