Description

在移动智能网上采用七号信令实现短消息业务的方法 技术领域 本发明涉及移动智能网业务, 特别是指一种在移动智能网上采用七 号信令实现短消息智能业务的方法。 发明背景 近年来, 智能网技术和移动通信业务在全球范围内迅猛发展, 它们 的结合构成了移动智能网, 为众多的移动用户提供了丰富多彩的智能业 务。 移动智能网是在移动通信网的基础上叠加了智能层, 采用智能网的 结构与控制功能实现移动网上诸多增值业务的智能化。
目前, 在移动网中提供智能业务的一个简便方法是将移动网作为一 个接入网, 将智能业务呼叫汇接到固定网的业务交换点(SSP ), 由 SSP 来实现移动网和智能网的互连, 如此能够迅速满足部分智能业务要求 , 但由于接续信令的限制以及固定网的业务交换点不具备移动网中的诸 多特点, 因此该方法不仅要占用一些号码资源供当前智能用户专用, 而 且只能提供有限的智能业务, 不能支持移动网上短消息的智能业务。
于是, 欧洲远程通信标准研究所(ETSI ) 又推出了移动网增强型逻 辑的客户化应用 (CAMEL ), 就是为了解决 GSM移动通信网与智能网 的互连问题。 在 GSM中引进 CAMEL业务, 运营商建立了一个智能平 台, 定义和实施新的增值业务, 可以满足用户在实现国际漫游的同时, 还享受与归属网络同样的服务。 但是, 由于短消息中心 (SMSC ) 与智 能网的业务控制点( SCP )之间没有实现短消息 CAMEL应用部分( CAP ) 的协议和信令, 因此, CAMEL结构不支持短消息服务, 影响了用户的 使用, 是极其不便的。
有鉴于此, 在中国专利申请 CN 01109024.3中, 提出了一种在移动 智能网上提供短消息智能业务的方法,它是通过 TCP/IP协议实现 SMSC 与移动智能网的业务控制点 (SCP )之间的消息传递, 进一步完成触发 短消息智能业务的鉴权操作和短消息结果通知操作。 但该方法在实施时 首先要在 SCP的前端增设一个应用接口 ,利用该接口建立 SMSC与 SCP 之间的 TCP/IP通信连接, 实际应用起来不是很方便。
由于智能网的实现是以 No.7信令网和大型集中数据库为基础, No.7 信令网为智能网各节点之间的联系提供了通信手段。 故此, 在七号信令 的通信基础上完善移动智能网的功能相对于采用 TCP/IP协议而言要简 单容易得多, 只需增加相关的信令即可, 不必考虑不同协议间的协议或 信令的转换问题, 无需借助更多的软件或硬件实体。 发明内容
因此, 本发明的主要目的在于提供一种在移动智能网上采用七号信 令实现短消息业务的方法, 使得在移动智能网上能筒单灵活的开放短消 息功能, 并使移动智能网的计费系统更完善。
本发明进一步的目的在于提供一种在移动智能网上采用七号信令实 现短消息业务的方法, 使运营商不必增加额外的网络实体, 即可实现向 标准 GSM智能网的平滑过度, 令组网和扩容更方便。
为达到上述目的, 本发明的技术方案是这样实现的:
一种在移动智能网上采用七号信令实现短消息智能业务的方法, 关 键在于该方法至少包括以下的步骤:
a、 主叫用户通过移动台向访问寄存器提交接入 /鉴权请求; b、 经访问寄存器鉴权后, 移动台向对应的主叫短消息移动交换中 心 (O— SM_MSC)发送短消息;
c、主叫短消息移动交换中心收到该短消息后,向互通功能的移动交 换中心 (IWMSC)上传该短消息;
d、 互通功能的移动交换中心 (IWMSC)才艮据短消息中被叫号段触 发相应的业务控制点( SCP ), 由 GSM业务控制功能( gsmSCF )和 GSM 业务交换功能 (gsmSSF)对短消息进行处理计费;
e、 同时, 互通功能的移动交换中心 (IWMSC)将短消息发给短消 息服务中心 (SMSC);
f、 短消息服务中心 (SMSC)收到该短消息后, 向网关移动交换中 心 (GMSC)提交短消息传送请求;
g、 网关移动交换中心 (GMSC)先向业务控制点 (SCP)发消息初 始化短消息检测点, 然后向归属寄存器 (HLR) 查询发送路由;
h、 查到被叫移动交换中心后, 网关移动交换中心(GMSC)向被叫 短消息移动交换中心 (T—SM— MSC)前传该短消息;
i、 被叫短消息移动交换中心(T一 SM_MSC)收到该短消息后, 向访 问寄存器 (VLR) 查询用户路由;
j、查到被叫移动台路由后,被叫短消息移动交换中心(T_SM— MSC) 将短消息发送给被叫移动台。
在上述通信过程中, 设定主叫短消息移动交换中心 (0—SM_MSC) 与互通功能的移动交换中心(IWMSC)之间采用移动应用部分(MAP) 消息进行通信。 被叫短消息移动交换中心(T— SM_MSC)与网关移动交 换中心 (GMSC)之间采用移动应用部分(MAP) 消息进行通信。 被叫 短消息移动交换中心(T_SM_MSC)与归属寄存器(HLR)之间采用移 动应用部分(MAP)消息进行通信。 归属寄存器(HLR)与网关移动交 换中心(GMSC)之间采用移动应用部分(MAP)消息进行通信。 GSM 业务控制功能(gsmSCF )与 GSM业务交换功能( gsmSSF )之间采用移 动网增强型逻辑的客户化应用 (CAMEL )应用部分(CAP )消息进行通 信。 互通功能的移动交换中心 (IWMSC )、 短消息服务中心 (SMSC ) 与网关移动交换中心( GMSC )之间通过短消息远端业务实体( SMRSE ) 通信。
由上述分析可见, 本发明所提供的在移动智能网上采用七号信令实 现短消息业务的方法,是完善了 SMSC与 SCP之间的 CAP信令和协议, 并且 4巴原来由 SSP完成的移动网和智能网的互连同时触发智能业务的功 能, 移动到 SMSC上, 由 SMSC完成, 如此, 不仅能够在移动智能网上 方便灵活的为移动用户开放短消息智能业务, 而且, 进一步的完善了移 动智能网的计费体系, 使其可提供短消息的预付费业务。 另外, 由于所 有功能均由 SMSC实现,那么网络结构发生变化时只涉及到 SMSC设备, 而不会影响到网上其它设备, 也不需要增加新的网络实体, 使得组网和 扩容更简单、 方便。 附图简要说明

图 5为本发明主叫 MT方式呼叫信令永久成功或失败的流程图。 实施本发明的方式
下面结合附图对本发明进行详细描述。
智能网的实现是以 No.7信令网和大型集中数据库为基础。 No.7信 令网为智能网各节点之间的联系提供了通信手段, 智能网功能实体之间 的标准信息流通过 No.7信令网的事务处理能力应用部分(TCAP )协议 进行传输。
由于智能网的通信基础是 No.7信令网, 因此, 只要在原有的基础上 完善 No.7 信令网的协议和信令, 便可使其既能保留原有的功能, 又能 更进一步的支持新增功能的通信。 目前, 在 GSM 网络中, 短消息服务 为移动用户的使用提供了很多方便, 包括了多种具有吸引力的增值业 务, 比如: 收发短消息; 通过短消息查询天气、 航班、 股票等所需信息 等等服务。 而现有智能网中的 No.7信令网支持不了该短消息的智能业 务, 那么就需要在原有的 No.7信令网的信令基础上增加完善支持短消 息通信的信令和协议即可。 基于该思想, 本发明实现短消息智能业务的 方法就是在主叫 MO端和被叫 MT端与 MSC、 SCP之间分别增加了有 关短消息请求、 鉴权以及发送等符合 7号信令和协议的通信消息, 以使 短消息智能业务能在移动智能网上顺利实现, 而不受任何限制。 根据该 主导思想,本发明结合现有的移动智能网结构,提出了相应的改进方案, 其具体操作如下所述:
本发明的实现方案是采用叠加短消息服务系统( OVERLAY SMS ) 的方式, 它是在普通 GSM网络上提供接入 CAMEL网络的一种叠加网 络方式, 即以 OVERLAY方式, 将普通 MSC / GM-SC接入到少数具有 IP功能的交换机上, 实现智能用户在一定区域内漫游。 它也是辟出一部 分号码资源供当前智能用户专用, 通过对特定号码段的识别来识别智能 业务, 即通过互通功能的移动交换中心(IWMSC )按号段判断触发哪一 个 SCP, 它是^ «现在由 SSP完成的移动网和智能网的互连并触发智能业 务的功能, 转由 IWMSC来完成。
OVERLAY SMS的网络结构如图 1所示,主要由 gsmSCF、 gsmSSF、 主叫移动台、 被叫移动台、 主叫短消息移动交换中心 (0—SM一 MSC )、 被叫短消息移动交换中心 (T_SMJVISC:)、 综合功能移动交换中心及归 属寄存器(HLR )构成。 gsmSCF和 gsmSSF之间通过 CAMEL应用部 分 ( CAP ) 接口连接, gsmSSF 通过外部接口连接 0_SM__MSC, 0一 SM_MSC、 T_SM_MSC, HLR均通过移动应用部分(MAP )接口连 接综合功能移动交换中心。 该综合功能移动交换中心至少包括互通功能 的移动交换中心 (IWMSC )、 短消息服务中心(SMSC )、 网关移动交换 中心(GMSC )。其中, IWMSC的作用是把短消息下发到 MSC。 IWMSC SMSC及 GMSC在网络建设中可以合设, 即只用一个网络实体, 提供三 个网络实体的功能, 合设可以节省设备, 减小投资。 当用户使用量大时, IWMSC、 SMSC及 GMSC也可以分设,以提高处理能力。 IWMSC、 SMSC 及 GMSC之间通过短消息远端业务实体(SMRSE )接口相互通信。
如图 1所示, 上述结构的通信过程至少包括以下的步骤:
a、 主叫用户通过移动台向访问寄存器提交接入 /鉴权请求; b、经访问寄存器鉴权后,移动台向对应的主叫短消息移动交换中心 ( 0_SM_MSC )发送短消息;
c、主叫短消息移动交换中心收到该短消息后, 向互通功能的移动交 换中心 (IWMSC ) 上传该短消息;
d、 互通功能的移动交换中心 (IWMSC )根据该短消息中被叫号段 触发相应的业务控制点 (SCP ), 由 GSM 业务控制功能(gsmSCF )和 GSM业务交换功能(gsmSSF )对短消息进行处理计费;
e、 同时, 互通功能的移动交换中心 (IWMSC )将短消息发给短消 息服务中心 (SMSC );
f、 短消息服务中心 (SMSC )收到该短消息后, 向网关移动交换中 心 (GMSC )提交短消息传送请求; g、 网关移动交换中心(GMSC )先向业务控制点(SCP )发消息初 始化短消息检测点, 然后向归属寄存器 (HLR ) 查询发送路由;
h、 查到被叫移动交换中心后, 网关移动交换中心(GMSC )向被叫 短消息移动交换中心 (T_SM_MSC ) 前传该短消息;
i、 被叫短消息移动交换中心(T_SM_MSC )收到短消息后, 向访问 寄存器 (VLR ) 查询发送路由;
j、查到被叫移动台路由后,被叫短消息移动交换中心(T— SM— MSC ) 将短消息发送给被叫移动台。
下面再参照图 2 ~ 图 5所示,对 OVERLAY SMS结构的信令处理流 程进行详细的描述。 图 2、图 3和图 4、图 5分别给出了 OVERLAY SMS 结构下, 主叫方 MO端或被叫方 MT端的信令处理流程。
如图 2所示, OVERLAY SMS结构 MO端具体的处理流程如下: 1、移动台 MS首先向 VLR提交访问请求和可选的鉴权请求(Access request and possible authentication );
2、 当移动台 MS 收到许可后, 移动台 MS 向 MSC提交短消息
( Message transfer );
3、 MSC收到该短消息后, 用 MAP消息向 IWMSC (即: 接入 /互通 MSC, InterWorkingMSC )上传短消息( forward Short Message ),该 IWMSC 负责处理手机提交的短消息;
4、 IWMSC收到该短消息后, 按号段判断应该触发哪一个 SCP, 而 后, 用 CAP 消息向相应的 SCP 发送初始化目的地信令点消息 INITIALDPSMS;
5、 SCP收到后 INITIALDPSMS消息后, 用 CAP消息回复连接 /继 续 SMS消息( CONNECT/ CONTINUE SMS )指示继续处理; 对于永久 成功或永久失败, SCP收到 IWMSC发的 INITIALDPSMS消息后 , 则以 CAP消息形式回复 CONTINUE SMS消息指示终止处理。
关于永久成功或失败,可从 INITIALDPSMS消息中的参数看出,该 参数是触发检出点 TDP, 如果 TDP为 0一 SMS_Submitted则表示成功; 如果 TDP为 0一 SMS_Failure则表示失败, 如图 3所示。
6、如杲成功, IWMSC以 MAP消息形式向被叫用户 SC提交短消息 ( Message transfer ), 同时 SCP计费, 然后结束 SMS处理, 结束的原因 会通知移动台;
7、 用户收到后也以 MAP消息形式向 SMS-IWMSC应答传送报告 ( Delivery report );
8、 IWMSC以 MAP消息形式将传送报告( Delivery report )继续回 送给 MSC;
9、 MSC再向 MS回送传送报告 ( Delivery report )。
如图 4所示, OVERLAY SMS结构中 MT端具体的处理流程如下:
1、 短消息中心用户 SC向 SMS-GMSC ( GMSC: GatewayMSC, 即 网关 MSC, 负责处理下发短消息)提交消息传送请求 Message transfer;
2、 网关 SMS-GMSC向 SCP发送 INITIALDPSMS消息, 指示初始 化短消息检测点, 该消息为 CAP消息;
3、 SCP 以 CAP 消息形式向网关 SMS-GMSC 发送 CONNECT/ CONTINUE SMS消息, 指示继续处理; 对于永久成功或失败, SCP收 到网关 SMS-GMSC发的 INITIALDP SMS消息,指示终止短消息检测点 后, 向网关 SMS-GMSC发送 CONTINUE消息, 指示终止处理。
关于永久成功或失败,可从 INITIALDPSMS消息中的参数看出 ,该 参数是触发检出点 TDP, 如果 TDP为 T—SMS一 Submitted则表示成功; 如果 TDP为 T_SMS_Failure则表示失败, 如图 5所示。
4、网关 SMS-GMSC以 MAP消息向 HLR查询发送路由 sendRouting InfoForShort Msg;
5、 网关 SMS-GMSC向 MSC前传短消息 forwardShortMessage, 该 消息为 MAP消息;
6 、 MSC 以 MAP 消 息形 式向 VLR 查询发送路 由 sendlnfoForMT-SMS;
7、 MSC以 MAP消息形式向移动台 MS发送短消息 Message transfer;
8、 MS以 MAP消息形式向 MSC回送转发 4艮告 Message transfer;
9、 MSC 以 MAP消息形式向 SMS-GMSC回送转发报告 Delivery report;
10、 SMS-GMSC也以 MAP消息形式向 HLR和用户回送转发报告 Delivery report。
在上述信令流程中, InitialDPSMS消息中包括的关键参数有: 主叫 号码、 被叫号码、 SMSC地址、 业务键以及触发检出点 (TDP ) 事件, InitialDPSMS消息中具体的参数名称及其描述如表一所示:
信息元素名称 描述
Destination Subscriber Number 包含目的短消息实体的编号
Calling Party Number 发送短消息用户的移动台 ISDN号码
Event Type 事件类型 (如 SMS_Collected_Info)
IMSI 标识移动用户
Location Information in MSC MSC中的位置信息
Location Information in SGSN SGSN中的位置信息
Service Key 业务鍵, 确定 gsmSCF中的业务逻辑处 理
Time And Timezone gsmSSF/gprsSSF触发的时间及其驻留的 时区
TP Short Message Submission 包含: - 信息类型指示
Specific Information
拒绝复制
有效周期格式
- 状态报告请求
- 用户数据头指示
- 响应路径
TP Protocol Identifier 指示短消息传输层协议
TP Data Coding Scheme 指示 TP用户字段的数据编码方案
TP Validity Period 指示有效周期的长短或有效周期中断的 绝对时间
SMSC Address 定义 MO短消息提交的 SMSC地址 表一 InitialDPSMS的消息构成 在 InitialDPSMS消息中事件类型 Event Type根据 CAMEL检测点类 型又分为三种, 如表二所示:
Figure imgf000013_0001
表二 Event Type的消息构成
在上述信令流程中, 由 SCP发给 MSC的 RequestReportSMSEvent 消息的主要参数是 SMS Event, 用于表示报告的事件已发出请求。 其中,
SMS Event又包括事件类型和监控模式, 其定义如表三所示:
Figure imgf000013_0002
表三 SMS Event ό 组成
在上述信令流程中, 由 SCP发给 SMS-GMSC 的连接 SMS 消息 ConnectSMS, 可以用来更改 SMSC地址和被叫号码等信息。 如杲 SCP 发给 MSC继续 SMC消息 ContinueSMS,表示 SCP请求 gsmSSF/gprsSSF 继续处理 SMS。
在实际应用中, 还有一种移动智能网络结构, 即: CAMEL短消息 服务系统( CAMEL SMS ), CAMEL SMS网络结构应用于 CAMEL环境 中, 其是在 CAMEL中定义了相应的网络实体, 如 SCP、 SCE、 SSP等, 并对各网络实体的功能做了相应的规定, 分别对应不同的功能实体, 如 GSM业务控制功能 gsmSCF、 GSM专用资源功能 gsmSRF、 GSM业务 交换功能 gsmSSF等。 在 CAMEL环境中, 智能业务采用 CAMEL签约 信息触发, 即当用户发起呼叫或被动接收呼叫时, 交换平台要查询用户 信息中是否带有发端 CAMEL用户签约信息 (0-CSI )或终端 CAMEL 用户签约信息 (T-CSI ), 如果有, 则触发 CAMEL智能业务的操作。 CAMEL SMS结构与 OVERLAY SMS结构主要的不同点在于:触发网不 同。 CAMEL SMS结构是在 MSC/SSP上查询 HLR来决定触发哪一个 SCP, 而不是 IWMSC。
