技术领域technical field
本发明涉及移动通信技术领域，尤其涉及一种基于IMS（IP MultimediaSubsystem，网际协议多媒体子系统）的呼叫控制方法、装置及系统。The present invention relates to the technical field of mobile communication, in particular to a call control method, device and system based on IMS (IP Multimedia Subsystem, Internet Protocol Multimedia Subsystem).
背景技术Background technique
为了满足用户更新颖、更多样化的多媒体业务需求，3GPP（The3rd GenerationPartnership Project，第三代合作伙伴计划）组织在原有分组承载网的基础上引入了IMS，IMS被认为是下一代网络的核心技术，其不仅能向用户提供传统的语音业务，还能向用户提供丰富的多媒体体验，是解决移动与固网融合，引入语音、数据、视频三重融合等差异化业务的重要方式。In order to meet the newer and more diverse multimedia service requirements of users, 3GPP (The3rd Generation Partnership Project, Third Generation Partnership Project) organization introduced IMS on the basis of the original packet bearer network. IMS is considered to be the next generation network The core technology, which can not only provide users with traditional voice services, but also provide users with a rich multimedia experience, is an important way to solve the convergence of mobile and fixed networks, and introduce differentiated services such as triple integration of voice, data, and video.
目前，IMS网络的主要网元包括：CSCF（Call Session Control Function，呼叫控制实体）、HSS（Home Subscriber Server，归属用户服务器）以及AS（Application Server，应用服务器），其中：At present, the main network elements of the IMS network include: CSCF (Call Session Control Function, call control entity), HSS (Home Subscriber Server, home user server) and AS (Application Server, application server), among which:
所述CSCF可分为P-CSCF（Proxy-Call Session Control Function，代理呼叫会话控制功能实体）、I-CSCF（Interrogating-Call Session Control Function，查询呼叫会话控制功能实体）和S-CSCF（Serving-Call Session Control Function，服务呼叫会话控制功能实体）三种类型，其中，S-CSCF作为IMS网络的核心呼叫控制实体，可实现基本的呼叫控制功能；The CSCF can be divided into P-CSCF (Proxy-Call Session Control Function, proxy call session control function entity), I-CSCF (Interrogating-Call Session Control Function, inquiry call session control function entity) and S-CSCF (Serving- Call Session Control Function, service call session control function entity) three types, among them, S-CSCF as the core call control entity of the IMS network, can realize the basic call control function;
所述HSS用于记录IMS网络中各用户的用户签约数据、配合CSCF实现路由功能并提供认证、授权等功能；其中，所述用户签约数据可在用户注册时从HSS下载到S-CSCF中，且所述用户签约数据中包含有用户的IFC（Initial Filter Criteria，业务触发规则，也可称为初始过滤规则），所述IFC中包含有提供业务的AS的地址信息；用户在进行呼叫时，S-CSCF可根据IFC中的配置信息触发到相应的AS，由相应的AS向用户提供其所需的语音业务、视频业务或其他补充业务等；The HSS is used to record the user subscription data of each user in the IMS network, cooperate with the CSCF to implement routing functions, and provide functions such as authentication and authorization; wherein the user subscription data can be downloaded from the HSS to the S-CSCF during user registration, In addition, the user's subscription data includes the user's IFC (Initial Filter Criteria, service trigger rule, which can also be called the initial filter rule), and the IFC includes the address information of the AS that provides the service; when the user makes a call, The S-CSCF can trigger the corresponding AS according to the configuration information in the IFC, and the corresponding AS will provide the user with the required voice service, video service or other supplementary services, etc.;
所述AS作为IMS网络的重要设备，可对S-CSCF触发到自身的呼叫进行相应控制，并返回呼叫放通或呼叫释放响应消息给S-CSCF，以便S-CSCF根据接收到的呼叫响应消息对用户发起的呼叫进行放通或释放处理，因而，当AS故障时将会直接影响用户的业务感知。具体地，为了解决上述问题，3GPP IMS相关规范中定义，当AS故障时，用户呼叫会话的接续控制将由IFC中的“Default AS Handing（容灾参数）”来约束，当所述容灾参数设置为“SESSION_CONTINUED（呼叫放通）”时，S-CSCF可放通呼叫，当所述容灾参数设置为“SESSION_TERMINATED（呼叫终止）”时，S-CSCF可释放/终止呼叫。As an important device of the IMS network, the AS can control the call triggered by the S-CSCF to itself, and return a call release or call release response message to the S-CSCF, so that the S-CSCF can respond to the call according to the received call response message. The call initiated by the user is released or released. Therefore, when the AS fails, it will directly affect the service perception of the user. Specifically, in order to solve the above problems, 3GPP IMS related specifications define that when the AS fails, the connection control of the user call session will be constrained by the "Default AS Handing (disaster recovery parameter)" in the IFC. When the disaster recovery parameter is set When it is "SESSION_CONTINUED (call release)", the S-CSCF can release the call. When the disaster recovery parameter is set to "SESSION_TERMINATED (call termination)", the S-CSCF can release/terminate the call.
但是，在采用上述根据IFC中的容灾参数进行用户呼叫的控制的方式时，会存在以下问题：However, when the above method of controlling user calls based on the disaster recovery parameters in the IFC is adopted, the following problems may exist:
问题一、当被叫号码为长号码时，所有呼叫均能够放通，无法根据主叫号码的呼叫权限进行灵活控制；Problem 1. When the called number is a long number, all calls can be made through, and flexible control cannot be performed according to the calling authority of the calling number;
问题二、当被叫号码为短号码或者需要号码规整时，由于长短号的变换或者号码规整等操作需由AS进行，因此，当AS故障时，会导致此部分呼叫的失败；Question 2: When the called number is a short number or number adjustment is required, operations such as long and short number conversion or number adjustment need to be performed by the AS. Therefore, when the AS fails, this part of the call will fail;
问题三、对于被叫一号通业务，尤其是CS域（电路域）终端号码做主号码的被叫一号通业务，由于其号码转换部分需由AS进行，因此，当AS故障时，会导致此部分呼叫的失败。Question 3. For the called ONLY service, especially the called ONLY service in which the terminal number in the CS domain (circuit domain) is used as the main number, since the number conversion part needs to be performed by the AS, when the AS fails, it will cause The failure of this part of the call.
为了避免上述问题，在AS故障时，还可采用部署AS容灾设备的方式来解决主用AS故障所带来的呼叫异常问题。例如，当某一AS故障时，HSS可将归属于故障AS的用户业务转发到正常AS上；或者，通过定期产生主用AS数据库的变更数据脚本，并在备用AS上执行从而完成数据库的同步。In order to avoid the above problems, when the AS fails, the deployment of AS disaster recovery equipment can also be used to solve the abnormal call problem caused by the failure of the active AS. For example, when an AS fails, the HSS can forward the user services belonging to the failed AS to the normal AS; or, by periodically generating the data change script of the active AS database and executing it on the standby AS to complete the synchronization of the database .
但是，在采用部署AS容灾设备的方式来解决主用AS故障所带来的呼叫异常时，存在何时切换到容灾设备的问题。目前一般采用OPTIONS（功能）检测和链路检测方案，在主用AS设备故障或宕机等完全故障的情况下能够实现主、备用设备的快速切换；但是，在主用AS设备部分故障，如主用AS设备能够运行但是网络质量不高导致呼叫丢包或主用AS设备由于软硬件缺陷限呼等的场景下，无法将其快速切换到容灾设备，从而导致在此期间内并没有完善的呼叫放通机制，会极大地影响用户的业务使用，降低用户的业务体验。However, when adopting the method of deploying AS disaster recovery equipment to solve the abnormal call caused by the failure of the active AS, there is a problem of when to switch to the disaster recovery equipment. At present, the OPTIONS (function) detection and link detection schemes are generally adopted, which can realize the rapid switching of the active and standby devices in the case of complete failures such as failure or downtime of the active AS device; however, in the event of a partial failure of the active AS device, such as In scenarios where the active AS device can run but the network quality is not high enough to cause call packet loss or the active AS device is restricted due to software and hardware defects, etc., it cannot be quickly switched to the disaster recovery device, resulting in failure to complete during this period. The call release mechanism will greatly affect the user's service usage and reduce the user's service experience.
再有，在采用部署AS容灾设备的方式来解决主用AS故障所带来的呼叫异常时，由于一般情况下备用设备的数据相比于主用设备具有一定的滞后性，因此，在容灾设备启用后可能仍会存在部分场景下呼叫异常的问题，也会进一步使得用户的业务受到影响，降低用户的业务体验。In addition, when adopting the method of deploying AS disaster recovery equipment to solve the abnormal call caused by the failure of the active AS, the data of the standby equipment generally lags behind that of the active equipment. After the disaster device is enabled, there may still be abnormal calls in some scenarios, which will further affect the user's business and reduce the user's service experience.
综上所述，当AS故障（包括完全故障或部分故障）时，无论是采用根据IFC中的容灾参数进行用户呼叫的控制、还是采用部署AS容灾设备的方式来解决AS故障所带来的呼叫异常问题时，均无法达到及时对S-CSCF触发到各AS的呼叫进行合理灵活地控制的效果，会导致用户业务受损、降低用户的业务体验。To sum up, when the AS fails (including complete failure or partial failure), whether it is to control user calls according to the disaster recovery parameters in IFC, or to deploy AS disaster recovery equipment to solve the AS failure When there is an abnormal call problem, it is impossible to achieve reasonable and flexible control of calls triggered by the S-CSCF to each AS in a timely manner, which will cause damage to user services and reduce user experience.

下面结合说明书附图对本发明实施例作进一步说明，但本发明不局限于下面的实施例。The embodiments of the present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following embodiments.
实施例一：Embodiment one:
如图1所示，其为本发明实施例一中所述基于IMS的呼叫控制方法的流程示意图，所述方法可以包括以下步骤：As shown in FIG. 1, it is a schematic flow chart of the IMS-based call control method described in Embodiment 1 of the present invention, and the method may include the following steps:
步骤101：S-CSCF将用户发起的呼叫发送至AS。Step 101: The S-CSCF sends the call initiated by the user to the AS.
具体地，在用户发起呼叫时，所述S-CSCF可根据从HSS中获取到的与用户发起的本次呼叫相关的用户签约数据，获取与用户发起的本次呼叫相对应的AS地址信息，并根据获取到的AS地址信息，将所述用户发起的本次呼叫发送至对应的AS。Specifically, when the user initiates a call, the S-CSCF may obtain the AS address information corresponding to the current call initiated by the user according to the user subscription data obtained from the HSS related to the current call initiated by the user, And according to the acquired AS address information, send the current call initiated by the user to the corresponding AS.
步骤102：S-CSCF判断是否在设定时长内未接收到来自所述AS的呼叫响应消息，若是，则执行步骤103，否则，执行步骤1031。Step 102: The S-CSCF judges whether the call response message from the AS is not received within the set time period, if yes, execute step 103, otherwise, execute step 1031.
具体地，由于在现有技术中，当所述AS故障或部分故障（如限呼或网络质量不高导致丢包等）时，通常会出现S-CSCF在设定时长内无法接收到来自AS的呼叫响应消息（呼叫超时未响应）或接收到的呼叫响应消息为限呼释放消息这两种情况，因此，在本发明所述实施例中，可由S-CSCF在设定时长内未接收到来自AS的呼叫响应消息或接收到来自AS的限呼释放消息来表示AS存在故障的情况。Specifically, in the prior art, when the AS is faulty or partially faulty (such as call restriction or low network quality leading to packet loss, etc.), it usually occurs that the S-CSCF cannot receive information from the AS within a set period of time. The call response message received (the call timed out and no response) or the received call response message is a call barring release message. Therefore, in the embodiment of the present invention, the S-CSCF may not receive the call response message within the set time period. A call response message from the AS or a call barring release message from the AS is received to indicate that the AS is faulty.
进一步地，所述设定时长可以根据实际情况进行调整设置，例如，当对所述呼叫控制的处理效率要求较高时，可将所述设定时长设置为较低的数值；当对所述呼叫控制的处理效率要求较低时，可将所述设定时长设置为较高的数值，本发明实施例对此不作任何限定。Further, the set duration can be adjusted and set according to actual conditions. For example, when the processing efficiency of the call control is required to be high, the set duration can be set to a lower value; When the processing efficiency requirement of the call control is low, the set duration can be set to a higher value, which is not limited in this embodiment of the present invention.
步骤103：S-CSCF从历史呼叫数据存储装置中获取与发送至所述AS的本次呼叫所对应的主叫号码、被叫号码以及触发平台信息相匹配的历史呼叫处理结果，并在执行完本步骤后跳转至步骤104，其中，所述历史呼叫数据存储装置中存储有S-CSCF发送至各AS的历史呼叫所对应的历史呼叫处理信息。Step 103: The S-CSCF obtains the historical call processing result matching the calling number, called number and triggering platform information corresponding to the current call sent to the AS from the historical call data storage device, and after execution After this step, jump to step 104, wherein the historical call data storage device stores the historical call processing information corresponding to the historical calls sent by the S-CSCF to each AS.
具体地，在本发明所述实施例中，所述S-CSCF可通过以下方式从历史呼叫数据存储装置中获取与本次呼叫所对应的主叫号码、被叫号码以及触发平台信息相匹配的历史呼叫处理结果：Specifically, in the embodiment of the present invention, the S-CSCF can obtain the information matching the calling number, called number and trigger platform information corresponding to this call from the historical call data storage device in the following manner: Historical call processing results:
向所述历史呼叫数据存储装置发送呼叫结果获取请求，其中，所述呼叫结果获取请求中可以携带有S-CSCF发送至所述AS的本次呼叫所对应的主叫号码、被叫号码以及触发平台信息等呼叫关键信息；以及，Sending a call result acquisition request to the historical call data storage device, wherein the call result acquisition request may carry the calling number, called number and triggering number corresponding to the current call sent by the S-CSCF to the AS. call key information such as platform information; and,
接收所述历史呼叫数据存储装置返回的与S-CSCF发送至所述AS的本次呼叫所对应的主叫号码、被叫号码以及触发平台信息相匹配的历史呼叫处理结果，其中，所述历史呼叫处理结果是所述历史呼叫数据存储装置在根据所述呼叫结果获取请求中携带的本次呼叫所对应的主叫号码、被叫号码以及触发平台信息，从本地存储的历史呼叫处理信息中查询到与本次呼叫所对应的主叫号码、被叫号码以及触发平台信息相匹配的历史呼叫处理结果后发送的。receiving the historical call processing result returned by the historical call data storage device that matches the calling number, called number, and triggering platform information corresponding to the current call sent by the S-CSCF to the AS, wherein the historical The call processing result is the calling number, called number and triggering platform information corresponding to the current call carried in the call result acquisition request carried by the historical call data storage device, and is queried from the locally stored historical call processing information It is sent after receiving the historical call processing result matching the calling number, called number and triggering platform information corresponding to this call.
需要说明的是，在本发明所述实施例中，所述历史呼叫数据存储装置可通过以下方式对S-CSCF发送至各AS的历史呼叫所对应的历史呼叫处理信息进行存储：It should be noted that, in the embodiment of the present invention, the historical call data storage device may store the historical call processing information corresponding to the historical calls sent by the S-CSCF to each AS in the following manner:
步骤一：采集S-CSCF发送至各AS的历史呼叫所对应的历史呼叫处理信息；其中，各历史呼叫所对应的历史呼叫处理信息可包括所述历史呼叫所对应的主叫号码、被叫号码、触发平台信息（如AS地址信息）以及AS返回的历史呼叫处理结果（如呼叫放通、呼叫释放等呼叫响应信息）等信息，本发明实施例对此不作任何限定。Step 1: Collect historical call processing information corresponding to historical calls sent by the S-CSCF to each AS; wherein, the historical call processing information corresponding to each historical call may include the calling number and called number corresponding to the historical calls , triggering platform information (such as AS address information), and historical call processing results returned by the AS (such as call response information such as call release, call release, etc.), which are not limited in this embodiment of the present invention.
具体地，在本发明所述实施例中，所述历史呼叫是相对于S-CSCF发送至AS的本次呼叫（即当前呼叫）而言的；实际上，针对S-CSCF发送至各AS的每次呼叫，所述历史呼叫数据存储装置均可对所述呼叫对应的呼叫处理信息进行相应的采集，以便达到记录S-CSCF发送至各AS的每次呼叫的呼叫处理信息的目的。Specifically, in the embodiment of the present invention, the historical call is relative to the current call (that is, the current call) sent by the S-CSCF to the AS; in fact, for the call sent by the S-CSCF to each AS For each call, the historical call data storage device can collect the call processing information corresponding to the call, so as to achieve the purpose of recording the call processing information of each call sent by the S-CSCF to each AS.
进一步地，在本步骤一中，针对S-CSCF发送至各AS的每次历史呼叫，所述历史呼叫数据存储装置可采用主动采集的方式从S-CSCF中采集所述历史呼叫所对应的历史呼叫处理信息，也可以采用被动接收的方式，接收S-CSCF发送的所述历史呼叫所对应的历史呼叫处理信息，本发明实施例对此不作任何限。Further, in this step 1, for each historical call sent by the S-CSCF to each AS, the historical call data storage device can actively collect the historical call corresponding to the historical call from the S-CSCF The call processing information may also be passively received, and the historical call processing information corresponding to the historical call sent by the S-CSCF is received, which is not limited in this embodiment of the present invention.
步骤二：针对采集到的任一待存储历史呼叫处理信息，根据所述待存储历史呼叫处理信息中的主叫号码、被叫号码以及触发平台信息判断本地是否已存储有与所述待存储历史呼叫处理信息中的主叫号码、被叫号码以及触发平台信息相匹配的已存储历史呼叫处理信息，若是，则在将与所述待存储历史呼叫处理信息中的主叫号码、被叫号码以及触发平台信息相匹配的已存储历史呼叫处理信息进行删除后，对所述待存储历史呼叫处理信息进行存储，否则，直接对所述待存储历史呼叫处理信息进行存储。Step 2: For any collected historical call processing information to be stored, judge whether there has been stored locally according to the calling number, called number and trigger platform information in the historical call processing information to be stored. The stored historical call processing information that matches the calling number, called number, and triggering platform information in the call processing information, if so, will be combined with the calling number, called number, and After the stored historical call processing information matching the trigger platform information is deleted, the historical call processing information to be stored is stored, otherwise, the historical call processing information to be stored is directly stored.
也就是说，针对S-CSCF发送至各AS的任一历史呼叫，所述历史呼叫数据存储装置中所存储的与所述历史呼叫相对应的历史呼叫处理信息均是唯一且最新的。That is to say, for any historical call sent by the S-CSCF to each AS, the historical call processing information corresponding to the historical call stored in the historical call data storage device is unique and up-to-date.
进一步地，为了提高所述历史呼叫数据存储装置的容量利用率和效率，针对所述历史呼叫数据存储装置中所存储的任一历史呼叫处理信息，所述历史呼叫数据存储装置在判断所述历史呼叫处理信息的存储时间超过第二设定时长后，可对所述已存储历史呼叫处理信息进行删除处理；其中，所述第二设定时长可根据实际情况进行设置，本发明实施例对此不作任何限定。Further, in order to improve the capacity utilization and efficiency of the historical call data storage device, for any historical call processing information stored in the historical call data storage device, when the historical call data storage device judges the historical After the storage time of the call processing information exceeds the second set time length, the stored historical call processing information can be deleted; wherein, the second set time length can be set according to the actual situation, and this embodiment of the present invention Do not make any restrictions.
