Description

一种 IMS网络中的业务触发方法、 ***、计算机程序和存储介质技术领域 Service triggering method, system, computer program and storage medium in IMS network

本发明涉及移动通信核心网技术领域，尤其涉及一种 i:M:S网络中的业务触发方法、 ***、计算机程序和存储介质。 The present invention relates to the technical field of mobile communication core networks, and in particular, to a service triggering method, system, computer program and storage medium in an i:M:S network.

背景技术 Background technique

IMS网络是指基于 IP的多媒体子***，其特点是采用 SIP体系结构，具有接入无关性、支持用户漫游和用户数据的集中管理等特点，从而使 IMS实现网络融合成为可能。 IMS作为支持固定接入和移动接入的统一核心控制网络，是全业务运营的网络基础。 The IMS network refers to the IP-based multimedia subsystem. It features SIP architecture, access independence, user roaming and centralized management of user data, making it possible for IMS to achieve network convergence. As a unified core control network supporting fixed access and mobile access, IMS is the network foundation for full-service operations.

图 1是目前的 IMS核心网络***架构图。 Figure 1 is a diagram of the current IMS core network system architecture.

如图 1所示， IMS核心网络***包括归属用户服务器（HSS )、服务呼叫会话控制功能模块 ( Serving Call Session Control Function, S-CSCF)、 SIP应用服务器（SIP AS：)、 IMS业务交换功能模块 GM-SSF )、 OSA业务开放能力服务器（OSA-SCS)、多媒体资源功能处理器 (MRFC)、以及业务能力交互管理功能模块 ( SCI ) 等。 As shown in FIG. 1, the IMS core network system includes a Home Subscriber Server (HSS), a Serving Call Session Control Function (S-CSCF), a SIP Application Server (SIP AS:), and an IMS Service Switching Function Module. GM-SSF), OSA Service Open Capability Server (OSA-SCS), Multimedia Resource Function Processor (MRFC), and Service Capability Interaction Management Function Module (SCI).

现阶段的 IMS网络己可向用户提供多种业务，用户可选择其中一项或多项业务。当用户申请 IMS业务后，用户呼叫的信令流程进入 IMS域，由 IMS 核心网的 S-CSCF查询 HSS中的用户业务信息，触发到相应的一个或多个 SIP AS, 由 SIP AS向用户提供业务服务。 At this stage, the IMS network can provide users with multiple services, and the user can select one or more of the services. After the user applies for the IMS service, the signaling process of the user call enters the IMS domain, and the S-CSCF of the IMS core network queries the user service information in the HSS, and triggers the corresponding one or more SIP ASs, and the SIP AS provides the user with the SIP AS. Business services.

在 IMS网络中，业务的触发顺序是按照业务的优先级，一个一个串行触发的。如果有多个业务叠加，则当 S-CSCF收到会话初始请求时，会按照预先设置好的优先级，从高到低，依次触发。例如，媒体限制业务（BM) , 终端个人呼叫助理业务（ PCA) , 无条件前传业务（CFU ) , 多媒体消息呼叫秘书业务（MMCS ) ,假设它们的优先级分别为 1， 2， 3和 4，则会先触发 BM.，然后依次触发 T- PCA、 CFU和 MMCS。 In an IMS network, the order in which services are triggered is triggered serially one by one according to the priority of the service. If there are multiple service overlays, when the S-CSCF receives the initial session request, it will trigger according to the pre-set priority, from high to low. For example, Media Restricted Service (BM), Terminal Personal Call Assistant Service (PCA), Unconditional Forward Delivery Service (CFU), Multimedia Message Calling Secret Service (MMCS), assuming their priorities are 1, 2, 3 and 4, respectively. BM. will be triggered first, then T-PCA, CFU and MMCS will be triggered in turn.

具体实施方式 detailed description

如图 4所示，该方法包括： As shown in Figure 4, the method includes:

步骤 401，存储 IMS网络中不同业务之间是否能够并行触发的分析结果。步骤 402 , 根据所述分析结果确定 IMS用户签约的业务之间是否能够并行触发，对能够并行触发的多个业务，执行并行触发操作。 Step 401: Store an analysis result that can be triggered in parallel between different services in the IMS network. Step 402: Determine, according to the analysis result, whether the services contracted by the IMS user can be triggered in parallel, and perform parallel trigger operations on multiple services that can be triggered in parallel.

本发明中，通过分析各个业务的业务特性来确定 IMS网络中不同业务之问是否能够并行触发，例如，根据各个业务之间的嵌套关系来确定各个业务是否能够并行触发。 In the present invention, it is determined whether the services of different services in the IMS network can be triggered in parallel by analyzing the service characteristics of each service, for example, determining whether each service can be triggered in parallel according to a nested relationship between the services.

― F面举具体的例子对如何根据业务之间的嵌套关系确定不同的业务是否能够并行触发进行示例性说明，所举例子并不用于限制本发明。 The specific example of how to determine whether different services can be triggered in parallel according to the nested relationship between services is not illustrated to limit the present invention.

以一个用户同时开通 E讯业务和 IMS彩铃业务为例，这两个业务的顺序不会发生冲突，因此能够并行触发，即可同时向 E讯业务的应用服务器和 IMS 彩铃业务的应用服务器发送触发请求消息。 For example, if a user simultaneously opens the E-mail service and the IMS CRBT service, the order of the two services does not conflict. Therefore, the trigger can be triggered in parallel, and the trigger can be sent to the application server of the E-mail service and the application server of the IMS CRBT service at the same time. Request message.

以一个用户同时开通虛拟网业务和 IMS彩铃业务为例，虚拟网业务用于为用户提供短号呼叫服务，即用户拨打短号，然后网络侧先触发到虚拟网的应用服务器，翻译用户拨打的短号对应的长号，然后再根据该长号触发到 MS 彩铃业务的应用服务器，接续彩铃放音，因此虛拟网业务和彩铃业务是不能 For example, a virtual network service is used to provide a short number call service for a user. That is, the user dials the short number, and then the network side first triggers the application server to the virtual network, and the translation user dials. The long number corresponding to the short number is then triggered by the long number to the application server of the MS CRBT service, and the ring back tone is played. Therefore, the virtual network service and the CRBT service cannot be

替换页 (细则笫 26条) 并行触发的，且需要先触发虚拟网业务，再触发彩铃业务。 Replacement page (Article 26) Triggered in parallel, and the virtual network service needs to be triggered first, and then the CRBT service is triggered.

本发明可以通过触发优先级的方式识别各个业务之间的触发顺序，以及不同的业务是否能够并行触发，其中，触发优先级相同的各个业务是能够并行触发的业务。在触发业务时，先根据所述顺序串行触发，在每次触发时，如果有多个业务能够并行触发，则在该次触发时执行并行触发操作。例如，以一个用户同时开通虚拟网业务、 E讯业务和 IMS彩铃业务为例，虛拟网业务的触发优先级高于 IMS彩铃业务的触发优先级和 E讯业务的触发优先级， IMS彩铃业务的触发优先级和 E讯业务的触发优先级相同，则根据所述触发优先级先触发虚拟网业务，等待虛拟网业务的应用服务器返回触发响应消息后，再并行触发 E讯业务和 IMS彩铃业务。 The invention can identify the triggering sequence between the services in the manner of triggering the priority, and whether the different services can be triggered in parallel. The services that trigger the same priority are services that can be triggered in parallel. When the service is triggered, the serial trigger is first performed according to the sequence. At each trigger, if multiple services can be triggered in parallel, the parallel trigger operation is performed at the time of the trigger. For example, a virtual network service, an E-mail service, and an IMS CRBT service are simultaneously opened by a user. The triggering priority of the virtual network service is higher than the triggering priority of the IMS CRBT service and the triggering priority of the E-mail service. The triggering priority is the same as the triggering priority of the E-mail service. The virtual network service is triggered first according to the triggering priority. After the application server of the virtual network service returns the triggering response message, the E-mail service and the IMS CRBT service are triggered in parallel.

其中，执行并行触发操作包括：针对可以并行触发的多个业务，同时发送触发请求消息到相应的应用服务器。 The performing the parallel triggering operation includes: sending a trigger request message to the corresponding application server for multiple services that can be triggered in parallel.

本发明中，可以在接收到 IMS用户的呼叫请求后，实时地根据所述分析结果确定 IMS用户签约的业务之间是否能够并行触发；本发明也可以预先根据所述分析结果确定每个 IMS用户签约的各个业务之间是否能够并行触发，存储每个 IMS用户的业务触发顺序，然后在接收到 MS用户的呼叫请求后，直接根据该 MS用户的业务触发顺序执行业务触发操作。下面分别予以详细说明，具体请参见图 5和图 6。 In the present invention, after receiving the call request of the IMS user, it may be determined in real time whether the services contracted by the IMS user can be triggered in parallel according to the analysis result; the present invention may also determine each IMS user according to the analysis result in advance. Whether the services of the contracted parties can be triggered in parallel, the service triggering sequence of each IMS user is stored, and then, after receiving the call request of the MS user, the service triggering operation is directly performed according to the service triggering sequence of the MS user. The following is a detailed description. See Figure 5 and Figure 6 for details.

本步骤中，同时向并行触发的各个业务对应的应用服务器发送触发请求消息。 In this step, a trigger request message is sent to the application server corresponding to each service triggered in parallel.

其中，在歩骤 503〜步骤 504中，可以先根据分析结果确定 IMS用户签约的各个业务中最先触发的业务，然后执行触发操作，判断该 IMS用户签约的所有业务是否都已被触发，如果该 IMS用户还有没触发的业务，则继续确定下一次触发的业务并执行触发操作，并返回所述判断的步骤，直至该 IMS用户签约的所有业务都已被触发为止。其中，每一次执行触发操作时，可以是触发单个业务，即向单个业务的应用服务器发送触发请求消息，也可以是触发能够并行触发的多个业务，即同时向能够并行触发的多个业务各自的应用服务器发送触发请求消息。 In step 503 to step 504, the service triggered by the first service of the IMS user may be determined according to the analysis result, and then the trigger operation is performed to determine whether all services subscribed by the IMS user have been triggered. If the IMS user still has no triggered service, it continues to determine the next triggered service and performs the triggering operation, and returns the step of determining until all the services subscribed by the IMS user have been triggered. Each time the triggering operation is performed, the single service may be triggered, that is, the trigger request message is sent to the application server of the single service, or the multiple services that can be triggered in parallel are triggered, that is, the multiple services that can be triggered in parallel are simultaneously The application server sends a trigger request message.

歩骤 ₄~歩骤 5 ,业务触发***根据所述触发顺序发现 CRJ业务和 MMCS 业务可以被并行触发，则业务触发***同时向 CFU 业务的应用服务器和 MMCS业务的应用服务器发送触发请求消息。业务触发***接收 CFU业务的应用服务器和 MMCS业务的应用服务器返回的业务触发响应消息，对所述业务触发响应消息进行整合，将整合后的业务触发响应消息返回给 S-CSCF。 Steps ₄ to 5: The service triggering system finds that the CRJ service and the MMCS service can be triggered in parallel according to the triggering sequence, and the service triggering system sends a trigger request message to the application server of the CFU service and the application server of the MMCS service. The service triggering system receives the service trigger response message returned by the application server of the CFU service and the application server of the MMCS service, and integrates the service trigger response message, and returns the integrated service trigger response message to the S-CSCF.

由图 11可见，与现有技术中按照业务优先级依次触发 BM:业务、 PCA 业务、 CFU业务和 MMCS业务相比，本发明通过并行触发 BM业务和 T-PCA 业务，以及并行触发 CFU业务和 MMCS业务，不仅提高了业务的触发效率，而且由于由专门的业务触发***来执行并行触发，因此也分担了 S- CSCF 的负载。 It can be seen from FIG. 11 that the present invention triggers the BM service and the T-PCA service in parallel, and triggers the CFU service in parallel, as compared with the prior art, which triggers the BM: service, the PCA service, the CFU service, and the MMCS service according to the service priority. The MMCS service not only improves the triggering efficiency of the service, but also shares the load of the S-CSCF because the parallel triggering is performed by a dedicated service triggering system.

另夕卜，对于触发响应消总的整合，以图 11中并行触发 BM业务和 T- PCA 业务为例，当这两个业务分别处理完 INVITE 消息后，业务触发***通过对比 INVITE头域和消息体中字段的变化，提取相应修改并整合到后续 INVITE In addition, for the integration of the trigger response cancellation, taking the BM service and the T-PCA service in parallel in FIG. 11 as an example, after the two services respectively process the INVITE message, the service trigger system compares the INVITE header field and the message. Changes in the fields in the body, extract the corresponding modifications and integrate them into the subsequent INVITE

替换页 (细则 26条) 请求中。例如，业务触发***发现 RECORD-ROUTE和 ROUTE头域的值冇修改，即 RECORD-ROUTE和 ROUTE头域分别加上了 BM业务和 T-PCA业务所在 AS的地址，则业务触发***提取相应的 AS地址并添加到后续 INVITE 请求的 RECORD- ROUTE和 ROUTE头域中；对消息体的修改也可按类似方式进行提取和合并。 Replacement page (rule 26) Requested. For example, the service triggering system finds that the values of the RECORD-ROUTE and ROUTE header fields are modified, that is, the RECORD-ROUTE and ROUTE header fields respectively add the addresses of the AS where the BM service and the T-PCA service are located, and the service triggering system extracts the corresponding AS. The address is added to the RECORD-ROUTE and ROUTE header fields of the subsequent INVITE request; modifications to the message body can also be extracted and merged in a similar manner.
