统一业务接入系统和接入方法
技术领域 本发明涉及智能网业务, 尤其指一种统一业务接入系统及接入方法。 背景技术 目前, 网络中同时存在着固定智能网、 GSM 智能网、 小灵通智能网、
CDMA智能网、 NGN (宽带)智能网等多种智能网, 当这些智能网提供具有 统一业务特性的智能业务时,需要这些智能网分别单独提供相同的智能业务。 例如提供预付费业务时, 需要在固定智能网、 GSM智能网、 小灵通智能网、 CDMA智能网、 宽带智能网等多个智能网络上分别提供预付费业务。 可见, 当出现了新的业务, 并需要由这些智能网提供时, 不得不对各个 智能网分别进行业务开发和加载, 可见这种业务提供模式不利于业务的快速 提供, 并且由于各个网络的智能业务相互独立, 也增大了维护成本, 例如, 当对预付费业务进行升级时, 则不得不对各个网络的预付费业务分别进行升 级。 发明内容 有鉴于此,本发明的主要目的在于提供一种统一业务接入系统和接入方 法, 以实现一种业务可以支持不同网络的接入。 本发明提供的统一业务接入系统, 包括: 业务提供单元, 存储有应用业务信息; PARLAY状态机, 用于根据来自 PARLAY适配器的业务请求信息触发 业务提供单元的应用业务, 以及将根据所述应用业务信息生成的呼叫控制信 息返回 PARLAY适配器;
PARLAY适配器, 用于实现 PARLAY状态机与网络状态机之间信息传 输格式的转换; 网络状态机,用于根据来自网络协议适配器的呼叫生成业务请求信息发 送给 PARLAY适配器, 以及将来自 PARLAY适配器的呼叫控制信息发送到 网络协议适配器; 网络协议适配器,用于实现网络状态机与业务交换设备之间信息传输格 式的转换; 业务交换设备,用于根据网络终端的呼叫触发应用业务上报网络协议适 配器, 以及根据来自网络协议适配器的呼叫控制信息控制当前的呼叫。 其中, 所述业务交换设备包括: 业务交换点 SSP和信令接口单元 SIU。 其中, 所述网络'状态机和网络协议适配器包括: 固网状态机和 INAP协 议适配器、 GSM状态机和 CAMEL协议适配器、 以及 CDMA状态机和 WIN 协议适配器中的至少一种组合。 其中,该系统进一步包括: SIP协议适配器,用于软交换设备与 PARLAY 状态机之间信息传输格式的转换; 软交换设备, 用于根据软交换网络的呼叫 触发应用业务上 R SIP协议适配器。 本发明相应的提供了一种统一业务接入系统的接入方法, 包括以下步 骤:
A、 业务交换设备根据网络终端的呼叫触发业务, 通过网络协议适配器 转换成网络状态机需要的格式传输给网络状态机;
B、 网络状态机通过 PARLAY适配器 4巴呼叫信息转换成 PARLAY状态 机需要的格式传输给 PARLAY状态机; C、 PARLAY状态机触发业务提供单元上的应用业务, 业务提供单元下 发呼叫控制到 PARLAY状态机;
D、 PARLAY状态机通过 PALAY协议适配器转换成网络状态机需要的 格式传输给网络状态机;
E、 网络状态机通过网络协议适配器转换成业务交换设备需要的格式传 输给业务交换设备以进行后续的呼叫。 可选的, 步骤 B 之前进一步包括: 网络状态机判断所述呼叫签约到业 务提供单元上时, 执行步骤 B; 网络状态机判断所述呼叫签约到网络状态机 所属网络的网络业务提供单元上时, 将呼叫触发到网络状态机所属网络的网 络业务提供单元。 其中, 步骤 A 所述业务交换设备根据网络终端的呼叫触发业务, 通过 网络协议适配器转换成网络状态机需要的格式的步骤包括: 业务交换设备根 据网络终端的呼叫触发业务, 由 SIU将 载呼叫的 NO.7信令转换为 TCP/IP 协议 4艮文发送到网络协议适配器; 网络协议适配器解析所述 TCP/IP 协议4艮 文转换成网络状态机需要的内部格式。 其中, 步骤 E 所述网络状态机通过网络协议适配器转换成业务交换设 备需要的格式传输给业务交换设备的步骤包括: 网络协议适配器将内部格式 的; ¾文转换为 TCP/IP协议4良文发送给 SIU; SIU将所述 TCP/IP协议4良文转 换为 NO.7信令格式传输给业务交换设备。 由上可以看出, 本发明提供的统一业务接入系统和接入方法, 可以实现 一个业务支持不同的网络协议的接入, 即实现了支持不同智能网络的接入。 具体来说, 即业务只需要提供一个, 但是可以支持多协议接入, 如窄带固网 INAP协议接入、 小灵通和 GSM的 CAMEL协议接入、 CDMA的 WI 协议 接入、 基于软交换或者 IMS ( IP多媒体子系统) 宽带智能网接入等。 可见, 使用本发明, 业务只需要一次开发和加栽即可支持多种网络协议 的接入, 实现了为不同的网络提供同一智能业务服务, 减少了业务的重复开 发, 有利于新业务的快速提供。 并且, 由于业务统一接入, 也利于业务的维 护。 附图说明 图 1为统一业务接入系统的示意图; 图 2为统一业务接入系统的一具体实施例的示意图; 图 3为统一业务接入系统的业务接入流程图。 具体实施方式 如图 1示出了统一业务接入系统的系统框图, 包括: 业务提供单元, 存 储有基于 PARLAY 应用接口开发的应用业务信息, 用于处理 PARLAY状态 机请求的呼叫。 PARLAY状态机, 用于根据来自 PARLAY适配器的业务请求 信息调用业务提供单元存储的应用业务, 以及 居所调用的应用业务生成呼 叫控制信息返回 PARLAY 适配器。 PARLAY 适配器, 用于网络状态机与 PARLAY状态机之间信息传输格式的转换。 网络状态机, 存储有业务所相关 的各个不同的子状态及关联的动作, 用于 据来自网络协议适配器的呼叫生 成业务请求信息发送给 PARLAY适配器, 以及将来自 PARLAY适配器的呼 叫控制信息发送到网络协议适配器。 网络协议适配器, 用于进行业务交换设 备与网络状态机之间信息传输格式的转换。 业务交换设备, 用于接入其所在 网络的呼叫及触发智能业务。 其中, 可以存在多个不同网络的网络状态机、 网络协议适配器和业务交换设备, 以实现对不同网络的接入。 另外, 还可以 为 NGN网络提供软交换设备进行接入, 软交换设备通过 SIP协议适配器与 PARLAY状态机进行通信。 如图 2示出了上述接入系统的一个具体的实施例,可支持固定智能网业 务、 GSM移动智能网业务、 CDMA移动智能网业务的接入。 对应的网络状 态机分别为固网状态机、 GSM状态机、 CDMA状态机, 网络协议适配器分 别为 INAP协议适配器、 CAMEL协议适配器、 WI 协议适配器。 业务交换 设备由 SSP和 SIU组成, 其中 SSP用于实现业务交换和智能业务的触发, SIU用于实现 SSP与网络协议适配器之间信息传输格式的转换, SIU与 SSP 之间采用 NO.7信令进 ^"通信, SIU与网络协议适配器之间可采用 TCP/IP协 议进^"通信。 下面参见图 3对图 2示出的接入系统业务接入过程进行描述,业务接入 过程包 4舌以下步骤: 步骤 301 : 业务交换设备触发呼叫到网络协议适配器。 例如, GSM网络、 固话网络以及 CDMA网络接收到各自网络终端的呼 叫后, 通过各自接入网内的 SSP触发智能网业务, SSP通过 NO.7信令将触 发智能业务的信令传送给 SIU单元, 由 SIU单元将 NO.7信令封装为 TCP/IP 协议报文后传送到网络协议适配器进行处理。 网络协议适配器包括各个网络对应的协议适配器。 例如, 固话网络对应 的是 INAP协议适配器、 GSM 网络对应的是 CAMEL协议适配器、 CDMA 网络对应的是 WIN协议适配器。 这里说明的是, 如果呼叫是通过软交换网络进行的, 由于网络使用的是
SIP协议, 则软交换网络直接触发 SIP协议适配器即可, 而不需要 SIU单元 进行协议解析。 步骤 302: 各网络协议适配器将接收的协议报文进行解析, 将报文承栽 的呼叫送到对应的网络状态机处理, 由网络状态机完成呼叫会话管理、 呼叫 状态迁移管理等和呼叫控制相关的功能。 其中, 各网络协议适配器与各网络 状态机之间采用内部协议进行通信。 例如: INAP协议适配器把呼叫送入固网状态机; CAMEL协议适配器 把呼叫送入 GSM状态机; WIN协议适配器把呼叫送入 CDMA状态机。 步骤 303: 各个网络状态机, 如固网状态机、 GSM状态机、 CDMA状 态机根据所述呼叫生成业务请求信息, 并将该请求信息送入 PARLAY 适配 器, 由 PARLAY适配器将接收的请求信息转换成 PARLAY状态机需要的格 式, 并送入 PARLAY状态机。 其中对于 SIP协议适配器, 由于所采用的协议与 PARLAY状态机均为 SIP协议, 因此可以直接触发呼叫到 PARLAY状态机; 如图 2中的虛线所示, 固网状态机、 GSM状态机以及 CDMA状态机也 可以直接触发各个状态机对应的业务, 如固网状态机触发固定智能网业务、 GSM状态机触发 GSM移动智能网业务、 CDMA状态机触发 CDMA移动智 能网业务。 而本例中此三个状态机则需要触发到 PARLAY适配器, 这是为了 实现本发明提出的单业务多协议接入。 其中, 为了实现网络的平滑升级, 新 业务可以由本发明提供的系统来提供, 原来各个网络的各个智能业务可以逐 步由本发明提供的系统来提供, 一段时间内可以仍由原各个网络提供原来的 各个智能业务。 这样, 可以在各个网络状态机收到所述呼叫后, 首先判断是 签约到本发明提供的系统的业务提供单元, 还是签约到原各个网络的网络业 务提供单元, 从而确定是执行后续步骤 304, 还是触发到所属网络的网络业 务提供单元提供智能业务。 步骤 304: 接收到业务请求信息后, 根据终端所签约的业务, PARLAY 状态机触发相应的 PARLAY业务, 向业务提供单元 "i奇求相应的应用业务。 步骤 305: 业务提供单元处理此请求, 根据所述业务请求调用相应的应 用业务, 执行业务逻辑处理返回控制信息给 PARLAY状态机, 指示 PARLAY 状态机后续操作。 步骤 306: PARLAY状态机生成相应的呼叫控制信息, 依次经 PARLAY 适配器、 网络状态机、 网络协议适配器返回到业务交换设备, 由业务交换设 备的 SSP执行后续的呼叫过程。 在信息传输过程中, 为了实现响应信息能够正确返回, 可以在上行信息 中加入所涉及的网络设备的标识, 如网络协议适配器、 网络状态机标识, 这 样就可以保证响应消息正确返回。 当信息由业务提供单元主动发出时, 则在 发出的信息中设置所需要的网络状态机标识, 即可将消息发送到网络状态机 所在网络了。 另外, 当网络终端是宽带网络的终端时, 如使用软交换设备或 IMS设 备进行汇接的用户终端, 由于采用 SIP协议, 因此可以直接经 SIP协议适配 器与 PARLAY状态机进行通信, 此处不再赘述。 由上可以看出, 统一业务接入系统和接入方法, 对于不同的网络, 可以 统一使用一个业务提供单元, 因此可以实现业务一次开发多网络接入触发, 很大程度了减少重复开发, 利于维护。 以上所述, 仅为本发明的较佳实施例而已, 并非用于限定本发明的保护 范围。
