一种交互式语音应答业务中实现计费的方法和系统
技术领域
本发明涉及电信通讯行业领域, 尤其涉及的是, 一种交互式语音应答业 务中实现计费的方法和系统。 背景技术
目前 OCS ( Online Charging System , 在线计费系统) 方式下的 IVR ( Interactive Voice Response, 交互式语音应答)业务为用户提供了诸如查询 余额、 充值、 查询亲情号码、 转账等一系列的单项服务, 对于用户使用 IVR 业务的计费问题, 釆用传统的 IVR业务计费模式的业务, 信令流程见图 1所 示, 说明 ¾口下:
101、用户起呼, MSC ( Mobile Switch Center,移动交换中心)根据 O— CSI ( Originating CAMEL Subscription Information, 始发 CAMEL签约信息)触发 业务, SCP( Service Control Point ,业务控制点)收到 IDP( Initial Detection Point , 初始检测点) 消息后, IVR业务判断被叫号码为管理接入码后, 进入 IVR管 理流程;
102、 SCP下发 RRBE ( Request Report BCSM Event, 请求报告 BCSM事 件) 、 0_ABANDON (主叫放弃) 、 CTR ( Connect To Resource, 链接到资 源)到 MSC/SSP ( Mobile Switch Center/ Service Switch Point, 移动交换中心 / 业务交换点) ;
103、 IVR业务向 OCS发送鉴权的 MML ( Man-Machine Language, 人机 命令语言)指令;
104、 OCS 接收到指令后, 内部处理, 然后返回结果 MML-ACK ( Man-Machine Language Acknowlegement, 人机命令语言响应) ; 如果鉴权 成功, 进入下一步, 否则结束会话;
105、 SCP进入主菜单下发 P&C ( Prompt And Collect User Information, 放音收号)消息到 MSC/SSP, 用户按照提示如"充值请按 1、 查询亲情号码请 按 2... ... , 结束呼叫请挂机"输入相应的数字选择流程。 通过 P&C— RES响应 消息返回用户的输入。
106、假设用户选择的是 2,即查询亲情号码(选择其他时处理流程相同 ) , 则 SCP向 OCS发送查询亲情号码的 MML指令(即 QUERY FNS ) 。 OCS接 收到指令后, 内部处理, 然后返回结果 MML-ACK。 如果查询成功, 进入下 一步, 否则结束会话或者返回主菜单, 返回 105;
107、 SCP通过向 MSC/SSP下发 PA消息, 提示用户查询亲情号码的结 果, 如"你的第 1个亲情号码是 XXX, 第 2个亲情号码是 XXX ... ... ";
108、 流程结束后, RC ( Release Call, 释放呼叫) , 返回主菜单。
通常, 用传统计费模式的 IVR业务有三种处理方式: 第一, 全部免费, 用户使用 IVR业务不用支付任何费用; 第二, 按次计费, 用户使用某个 IVR 业务比如查询账户余额、 充值等, 就要按照使用的次数来支付费用; 第三, 是前面两种方式的折中, 对于某些 IVR业务是免费的, 而另外一些 IVR业务 则需要支付费用, 具体实现是在 OCS侧, 根据不同业务流程釆取不同的扣费 策略, 有的免费, 有的按次收费。
但是, 上述几种方法都不能精确反映根据用户使用网络资源的时间来进 行收费, 缺乏科学性。 按次计费浪费用户的开支; 用户免费使用 IVR业务, 导致用户过多地占用话路资源, 不能够有效地控制 IVR业务流程过多的占用 话路资源、不利于运营商充分利用网络资源, 比如免费的 USSD ( Unstructured Supplementary Service Data, 非结构化补充数据)业务。
因此, 现有技术还存在缺陷, 有待于改进和发展。 发明内容

S2、 所述在线计费系统依所述鉴权指令实时地对该用户进行鉴权和话费 信息检查, 并在会话结束时根据所述业务控制点返回的会话时间进行扣费。
进一步地, 当所述业务控制点向在线计费系统发出鉴权指令而未收到其 返回的鉴权结果时, 所述步骤 S2还包括: 所述业务控制点结束会话, 并向所 述在线计费系统返回会话时间; 其中所述返回的会话时间是一预设的时长。
进一步地, 所述步骤 S2还包括: 当所述在线计费系统检查到所述用户的 话费不足时, 所述业务控制点结束所述会话, 并向所述在线计费系统返回会 话时间; 其中所述返回的会话时间是该用户已经使用的时长。
进一步地, 所述步骤 S2还包括: 接收到所述用户发出的结束信息时, 结 束所述会话。
进一步地, 所述方法还包括: 如果鉴权成功且话费充足, 所述在线计费 系统则给出本次授权时长;

进一步地, 所述方法还包括: 如果到达所述本次授权时长, 则通过所述 业务控制点中的已使用服务单元携带所述本次时长, 向在线计费系统申请后 次时长;
其中步骤 S2 中所述返回的会话时间是所述本次授权时长和所述后次时 长的累加。
进一步地, 所述方法还包括: 所述业务控制点多次向在线计费系统申请 后次时长;
其中步骤 S2 中所述返回的会话时间是首次授权时长与所述多次后次时 长的累加。
本发明还提供一种交互式语音应答业务中实现计费的系统, 包括业务控 制点和在线计费系统, 其中,
所述业务控制点包括:
参数模块, 其设置为实时地将用户的状态发送至在线计费系统; 时间模块, 其设置为监控所述用户的会话时间; 以及

进一步地, 所述业务控制点还包括:
与所述时间模块和参数模块连接的更新模块, 其设置为在到达所述授权 时长后, 触发所述参数模块更新用户状态。
与现有技术相比, 由于本发明釆用实时地对用户进行鉴权和话费信息检 查, 在会话结束后所述在线计费系统根据所述业务控制点返回的会话时间进 行扣费; 实现了对 IVR业务按照时间精确计费, 避免了传统的 IVR按次计费 的弊端, 节省用户的开支; 同时也克服了免费 IVR业务导致用户过多地占用 话路资源地问题, 充分地利用局方网络资源。
附图概述
图 1是现有技术中的 IVR业务信令流程图;
图 2是本发明的交互式语音应答业务中实现计费的系统示意框图; 图 3是本发明的交互式语音应答业务中实现计费的方法的信令图; 以及 图 4是本发明的方法中紧急流程时的 IVR业务信令流程图。 本发明的较佳实施方式
下面结合具体实施方式和附图对本发明作进一步详细的描述。
本发明解决了传统 IVR业务中不能有效地根据用户使用网络资源的时间 来进行收费, 不能够有效地控制 IVR业务流程过多的占用话路资源、 不利于 运营商充分利用网络资源的问题。本发明在 OCS方式计费下,利用 DCC( Dial Control Center, 拨号控制中心)接口, 在 IVR业务流程中通过 CCR/CCA ( Credit-Control-Reques/Credit-Control-Answer,信用控制请求 /信用控制应答 ) 消息到 OCS系统进行实时鉴权、 扣费, 实现对 IVR业务按照时间精确计费, 使得 OCS用户可以根据自己的需要选择使用 IVR还是 USSD业务,可以避免 传统的 IVR按次计费的弊端, 节省用户的开支, 且实施起来非常简单易行。
本实施方式包括正常情况和紧急情况, 正常情况的信令流程图见图 3 , 描述如下:
201、用户起呼, MSC根据 0— CSI触发业务, SCP收到 IDP消息后, IVR 业务判断被叫号码为管理接入码后, 进入 IVR管理流程。
202、 SCP下发 RRBE ( 0— ABANDON, 主叫放弃) 、 CTR ( Connect To
Resource, 链接到资源)到 MSC/SSP。
203、 SCP判断是否用 DCC来实时扣费的开关, 如果是, 则进入下一步, 如果不是, 执行步骤 103至步骤 107, 见图 1。
204、 SCP进行参数准备, 组包、 向 OCS发送 CCR INITIAL (初始 CCR ) 消息。
205、 OCS接收到 CCR消息后,根据用户的状态、余额等做出鉴权结论, 成功则预留扣费, 然后返回结果 CCA INITIAL (初始 CCA )消息。 SCP解包 获取结果参数, 如果鉴权成功, 进入下一步, IVR业务启动定时器, 定时器 的时间就是初始 CCA的授权时长; 否则结束会话。
206、 同步骤 105, 即 SCP进入主菜单下发 P&C ( Prompt And Collect User
Information, 放音收号) 消息到 MSC/SSP, 用户按照提示如"充值请按 1、 查 询亲情号码请按 2... ... , 结束呼叫请挂机"输入相应的数字选择流程。 通过
P&C RES响应消息返回用户的输入。 207、 同步骤 106, 即假设用户选择的是 2, 即查询亲情号码(选择其他 时处理流程相同),则 SCP向 OCS发送查询亲情号码的 MML指令(即 QUERY FNS ) 。 OCS接收到指令后, 内部处理, 然后返回结果 MML-ACK。 如果查 询成功, 进入下一步, 否则结束会话或者返回主菜单, 返回 206。
208、 同步骤 107, 即 SCP通过向 MSC/SSP下发 PA消息, 提示用户查 询亲情号码的结果, 如"你的第 1 个亲情号码是 XXX, 第 2 个亲情号码是 XXX "。
209、 当到达所述授权时长, 即预留时间用完(本实施方式中的预留时间 是 120s ) , SCP组包、 向 OCS发送 CCR UPDATE (更新 CCR ) 消息, 通过 已使用服务单元(Used Server Unit, USU )携带本次通话已经使用的时长, 再申请后次时长; OCS 再预留时长(即授权后次时长) , OCS 通过 CCA UPDATE (更新 CCA )返回授权时长, SCP重置定时器。 这样 IVR业务流程 继续。 需要指出的是更新消息组 CCR UPDATE/CCA UPDATE可以有多组。
210、 当用户费用用完或用户主动放弃时, 会话结束。 OCS出正常话单, 所述在线计费系统(OCS )根据所述业务控制点 (SCP )返回的会话时间进 行扣费; SCP发送 RC消息到 MSC/SSP, 释放会话。
通过图 1和图 3的比可以看出, 所述在线计费系统(OCS )根据会话时 间进行扣费, 如果话费不足, 则会话时间是已经使用的时长; 如果话费充足, 扣费的会话时长是首次授权时长与后次时长的积累; 实现了对 IVR业务按照 时间精确计费, 避免了传统的 IVR按次计费的弊端, 节省用户的开支; 同时 也克服了免费 IVR业务导致用户过多地占用话路资源地问题, 充分地利用局 方网络资源。
以上描述的是正常流程, 正常流程的结束条件是用户话费用完了或者用 户主动放弃会话时, 此时业务控制点 (SCP )在收到 CCA FINAL ( CCA结 束) 消息之后, 出正常话单, 话单迄止时间分别是会话开始和结束时间。 为 进一步的完善系统, 增加了紧急流程, 紧急流程的结束条件是在业务控制点 ( SCP )发出 CCR消息但未在预定的时间内收到相应的 CCA消息, 此时业 务控制点 (SCP ) 下发预定义的会话时长启动定时器, 会话结束 SCP返回会 话时间供 OCS釆集后补扣费。 紧急流程是在流程结束后出紧急话单,供 OCS 系统釆集后补扣费, 话单的时长就是所述预定义的会话时长。
紧急流程有三种情形:初始( CCR INITIAL )紧急、更新( CCR UPDATE ) 紧急、结束( CCR FINAL )紧急。三种情形处理类似,都是在业务控制点 ( SCP ) 发出 CCR消息但未在预定的时间内收到相应的 CCA消息时, 下发预定义的 会话时长启动定时器,会话结束 SCP返回会话时间供 OCS釆集后补扣费。这 里以初始紧急为例说明, 见图 4, 当没有收到 CCA初始消息, SCP下发预定 义的时长(一般为 15分钟)启动定时器, 其他处理和正常流程一样, 会话结 束后 SCP返回会话时间供 OCS釆集后补扣费。需要说明的是,在一次流程中, 只要出现一次紧急情形, 就直接跳转到出紧急话单。 正常话单和紧急话单通 过业务键来区分,从而包含业务键的话单文件的名称也不一样,这样方便 OCS 系统分拣, 大大提高系统效率。
表 1和表 2分别是 OCS信息表、 卡号段与 OCS对应关系表:
OCS信息表
Figure imgf000009_0001
对表 1的 0CS信息表做如下说明:
1、 每个 0CS信息的有以下几个配置项: 0CS索引 ocsid、 OCS主机名、 0CS域名、 OCS ip地址和端口号、 CCR命令标志、 0CS紧急时是否接续标 志和 0CS描述 description。 2、 ocsid为唯一索引, 唯一标示一个 0CS。
3、 OCS主机名、 OCS域名、 OCS i 地址和端口号为 SCP作为 DCC客 户端和 0CS服务端链接时用到的配置信息。
4、 CCR命令标志, 是 CCR包头的一个中的一个字段, 1表示请求型消 息, 3表示请求型消息, 并且可以被 proxy ( DCC代理)转发。
5、 0CS紧急时是否接续标志, 1可以继续会话, 0释放会话。
6、 配置项可以动态增加、 删除或修改。
表 2 卡号段与 0CS对应关系表
Figure imgf000010_0001
对表 2卡号段与 0CS对应关系表做如下说明:
1、 这张表比较简单, 包括字段是 0CS用户卡号段、 0CS索引。
2、 0CS用户卡号段 cardprefix为唯一索引, 唯一对应一个 0CS索引。 如 86139号段属于第一个 0CS, 鉴权消息 CCR需要发送到 10.40.155.73; 86159 号段属于第二个 0CS, 鉴权消息 CCR需要发送到 10.40.155.66。
3、 配置项可以动态增加、 删除或修改。
有了这两张表 IVR业务可以实现一个 IVR业务按照号段和多个 0CS进 行交互。 IVR业务根据主叫用户号码去和表 2从左最大匹配找出 0CS索引, 然后在表 1中找出对应的 0CS信息。 IVR业务就可以和该 0CS进行信息交 互, 实现实时鉴权、 扣费。
此外, 釆用基于 DIAMETER基础协议的 DCC ( Diameter credit control 基于 diameter的信任控制协议)接口中的 CCR、 CCA消息实时地对用户使用 IVR业务进行鉴权、扣费, 同时对用户正常地使用 IVR业务不产生任何影响, 业务控制点 (SCP )和在线计费系统(0CS )在计费时主要的处理过程如下:
100、 参数准备阶段: SCP准备所有 DCC协议级的参数(如源主机名、 源域名、 目的域名、 业务上下文, 详细说明见 RFC3588 ) 以及计费相关的参 数如主叫号码、 被叫号码、 主叫漫游位置信息;
200、 组包: SCP根据 DCC协议对每个 CCR包的定义和每个 AVP结构 的定义, 对 AVP赋值和 CCR包头赋值;
300、 发送、 接收 DCC消息包: SCP通过 DCC客户端接口机发送 CCR 请求消息, 并接受 OCS返回的 CCA消息;
400、 解包: OCS在收到 CCR请求消息之后, 根据用户的状态、 余额以 及 CCR消息中的计费有关的参数, 鉴权、 预留费用, 在鉴权成功且话费充足 时, 给所述用户给出授权时长处理好后将结果码、预留费用通过 CCA返回给 SCP, SCP要用解包算法获取到鉴权结果和授权服务单元 GSU;
500、 正常处理: 如果返回结果码正常 2XXX后, IVR业务继续; 如果返 回失败返回码 IVR业务终止;
600、 设置、 重置定时器: 相当于呼叫业务中的 AC ( Apply Charging, 申 请计费 ) 消息, 监控会话所用时间, 分段向 OCS发送已使用时长;
700、 紧急流程处理: 当 SCP与 OCS系统断链、 或者 OCS系统繁忙返回 3004、 或者到 OCS路由不可达时返回 3002时、 返回的 CCA参数异常(如 AVP缺失等), IVR业务通过开关控制 IVR业务流程是否继续。 允许继续的 话, IVR流程结束后, 出紧急话单, 供 OCS系统釆集后补扣费;
800、通过 DCC接口携带话费立显和用户优选语言相关 DCC消息字段实 现话费立显功能和才艮据 OCS用户的优选语言来放通知音的功能。
本方法对用户使用 IVR业务实时地鉴权、 预留费用, 会话结束后扣费。 如果用户费用不足, 提示用户后, 结束 IVR业务, 同时对已经使用的时长去 OCS扣费。 同时还可以通过 DCC接口实现话费立显功能, 根据 OCS用户的 优选语言来放通知音的功能。
本发明还提供一种交互式语音应答业务中实现计费的系统, 包括业务控 制点和在线计费系统, 框图见图 2, 业务控制点(SCP ) 包括: 参数模块, 时 间模块, 结束模块以及更新模块; 在线计费系统(OCS ) 包括: 扣费模块, 鉴权模块, 授时模块以及预留模块。
参数模块用于实时地将用户的状态发送至在线计费系统(OCS ) ; 时间 模块用于监控所述用户的会话时间; 结束模块用于结束本次对话; 扣费模块 用于接收所述结束模块的触发, 并根据所述参数模块发送的会话时间对所述 用户进行扣费; 鉴权模块与所述参数模块连接 , 用于根据所述参数模块发送 的用户状态进行鉴权; 授时模块与所述鉴权模块和时间模块连接, 在鉴权成 功且话费充足时, 给所述用户给出授权时长; 预留模块与所述鉴权模块连接, 用于在给出所述授权时长同时预留相应余额。 更新模块与所述时间模块和参 数模块连接, 用于在到达所述授权时长后, 触发所述参数模块更新用户状态。
本系统主要是在 SCP侧修改 IVR业务逻辑,在原有 IVR业务流程模块中 增加调用用于监控用户会话时间的时间模块, 用于在会话结束时根据会话时 间对用户进行扣费的扣费模块, 实现 SCP和 OCS之间实时计费信息地处理、 IVR流程监控, 流程结束后处理计费话单来实现上述目的。 按照时间精确计 费可以避免传统的 IVR按次计费的弊端, 节省用户的开支; 同时也可以克服 免费 IVR业务导致用户过多地占用话路资源的问题,充分利用局方网络资源。 本发明为 IVR业务流程增添了特色, 提高了用户的满意度, 提高了运营商的 网络资源利用效率, 本发明可广泛地用于世界各个国家、 地区的 IVR业务应 用系统中。
应当理解的是, 以上所提供的具体实施方式只是对本发明的说明, 而不 应当理解为对本发明的限制, 对本领域的普通技术人员来说, 可以根据上述 说明加以改进或变换, 而所有这些改进和变换都应为本发明所揭示的原理和 特征, 均属本发明的保护范围。
