具体实施方式
为了使本文实施例所要解决的技术问题、技术方案及有益效果更加清楚、明白，以下结合附图和实施例，对本文实施例进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本文实施例，并不用于限定本文实施例。
本发实施例一提供了一种窄带业务放音IP化的方法，该方法建立在MSC(Mobile Switching Center，移动交换中心)已经具备出SIP(Session Initiation Protocol，会话初始协议)接口的能力的基础上，其可利用如图4所示的系统架构实现，请参阅图1，方法流程包括：步骤S101、移动交换中心MSC将窄带呼叫请求通过信令接口模块SIU透传给SCP(Service Control Point，业务控制点)的窄带业务模块；步骤S102、该MSC接收并分析SCP返回的放音辅助路由的ETC(Establish Temporary Connection，建立临时连接)消息；步骤S103、当该ETC消息携带符合窄带放音IP化的信息时，该MSC将该ETC消息转化为会话初始协议SIP请求消息；步骤S104、该MSC将该SIP请求消息直接发送给该SCP的宽带业务模块，由该宽带业务模块根据该SIP请求消息与该SCP的窄带业务模块建立关联关系并通过该SCP的宽带协议适配模块控制媒体播放服务进行放音。
在一个方案中，步骤S102，包括：该MSC接收该SCP通过SIU透传的ETC消息；对该ETC消息携带的被叫号码进行分析，判断该被叫号码是否携带符合窄带放音IP化的前缀特征；当该被叫号码携带该前缀特征时，确定该ETC消息携带符合窄带放音IP化的信息。
在一个方案中，步骤S104包括：该MSC将该SIP请求消息发送给该SCP的宽带协议适配模块，由该宽带协议适配模块将该SIP请求消息通过内部消息发送给该SCP的宽带业务模块。
在一个方案中，步骤S101之后，该方法还包括：该SCP的窄带业务模块根据业务的处理要求组装被叫号码，并将组装的号码填写到ETC中；其中，该业务处理的要求为发起该窄带呼叫请求的用户签约的智能业务的业务要求；该被叫号码参数包括PREFIX前缀及窄带关联ID，该PREFIX前缀为窄带放音IP化的信息，该窄带关联ID用于SCP内部的宽带业务与窄带业务的关联处理。
在一个方案中，该SIP请求消息携带被叫号码，步骤S104之后，该方法还包括：该 宽带业务模块对该被叫号码进行分析；当该被叫号码携带符合窄带放音IP化的信息时，该宽带业务模块获取该被叫号码中的窄带关联ID；该宽带业务模块根据该窄带关联ID调用该SCP的窄带协议适配模块，通过该窄带协议适配模块与该SCP的窄带业务模块建立关联关系。
实际应用中当该宽带业务模块与该窄带业务模块建立关联关系之后，如果窄带业务模块接收到该呼叫请求后续的放音收号请求时，会将该放音收号请求发送给该宽带业务模块，而不是发送到MSC核心网。
在一个方案中，由该SCP的宽带协议适配模块控制媒体播放服务进行放音，包括：该宽带业务模块通过宽带协议适配模块呼叫该媒体服务，使该媒体服务与该MSC的主叫完成双向媒体协商；该宽带业务模块通过宽带协议适配模块向该窄带协议适配模块发送消息，通知窄带业务模块已准备好放音；当该窄带业务模块接收到该呼叫请求后续的放音收号请求时，调用窄带协议适配模块的内部接口进行PA(Play Announcement，放音)或PC(Prompt And Collect User Information，放音收号)操作；该窄带协议适配模块调用内部接口通知宽带协议适配模块进行PA或者PC操作；该宽带协议适配模块通过内部接口通知宽带业务模块进行PA或者PC操作；该宽带业务模块与该媒体服务进行交互完成PA或者PC操作。
本实施例的窄带业务放音IP化的方法，在MSC接收到携带窄带放音IP化的信息的ETC消息时，将ETC消息转化为会话初始协议SIP请求消息直接发送给SCP的宽带业务模块，无需独立IP放音，使用性能更高的宽带媒体服务器来播放窄带音。降低了系统的复杂度，增加了可维护性，从而能达到更快更好的响应客户的需求的目的，并且利用宽带的媒体服务器进行窄带放音，从硬件上避免了E1线的接入，实现了全网IP化。
在前述实施例的基础上，本文实施例提供了另一种窄带业务放音IP化的方法，需要说明的是，本实施例中窄带业务模块、宽带业务模块以及窄带协议适配模块、宽带协议适配模块均设置在同一个SCP中。请参阅图2，方法流程包括：
步骤S201、用户A发起窄带呼叫请求，MSC把此窄带呼叫请求通过IDP(Initial Detection Point，启动检出点)消息送到SIU。
本实施例中，用户A签约了某智能业务，该智能业务支持窄带放音IP化。
步骤S202、SIU通过内部消息把该IDP消息发送给SCP中的窄带业务模块。
步骤S203、SCP中的窄带业务模块依据用户A签约的智能业务的处理要求对被叫号码进行组装号码并将组装后的号码填入ETC中，然后调用窄带协议适配模块的ETC接口发送ETC消息给SIU，由该SIU把该ETC消息传给MSC。
在一实施方式中，组装的号码的格式为：PREFIX前缀+SCPID+相关呼叫ID，其中：PREFIX用于MSC对窄带业务放音IP化进行识别；SCPID用于在多SCP环境下sip消息的分发，确保把此sip消息分发到正确的SCP上处理，其作为窄带业务所在的服务器的模块标识，是一个非必选参数。
窄带会话窄带关联ID用于SCP内部做宽带业务模块和窄带业务模块的关联处理。
步骤S204、MSC收到ETC消息后，对其中的被叫号码进行分析，发现此被叫号码携带的PREFIX符合窄带放音IP化的前缀特征，MSC把此ETC消息转换为SIP INVITE消息，直接发送给指定的宽带协议适配模块。
在一实施方式中，指定的宽带协议适配模块是指在多SCP环境下，SCP ID对应的SCP的宽带协议适配模块。
在一实施方式中，该SIP INVITE消息中的被叫号码的格式与ETC消息中携带的被叫号码的格式相同。并且，该SIP INVITE消息还携带主叫的媒体描述信息SDP-CALLER。
本步骤中，MSC发送的SIP INVITE消息直接发送给SCP的宽带协议适配模块，无需经由SIU进行透传。
步骤S205、宽带协议适配模块把该SIP INVITE消息通过内部消息发送给宽带业务模块。
步骤S206、宽带业务模块分析该SIP INVITE消息的被叫号码，发现该SIP INVITE消息是从窄带放音IP化业务来的，解析出被叫号码中的窄带关联ID，并调用同一SCP下的窄带协议适配模块的接口，使窄带协议适配模块对本次放音会话做特殊标记处理。
在一实施方式中，通过本步骤，能够告知其此放音业务为窄带放音IP化的放音业务。窄带协议适配模块对本次放音会话做特殊标记处理，后续此放音会话的请求都需要转给对应的宽带协议适配模块。
步骤S207、宽带业务模块呼叫媒体服务MEDIASERVER，并在MEDIASERVER应答后，携带此次放音的窄带关联ID调用窄带协议适配模块的内部接口发送ARI消息，由窄带协议适配模块内部通知窄带业务模块该ARI消息，以便窄带业务模块继续做PA或者PC操作。
在此步骤中，宽带放音业务控制宽带协议模块给MSC发送SIP 180RING或183PROCESSING或200OK消息，其中，该消息需要携带MEDIASERVER的媒体描述信息SDP-MS。
步骤S208、窄带业务模块进行PA或者PC操作并调用窄带协议适配模块的内部接口，窄带协议适配模块依据步骤S206中记录的特殊标记，识别出这是一个窄带放音IP话的业务，依据内部建立的关联关系，调用内部接口通知宽带协议适配模块进行PA或者PC操作。
步骤S209、宽带协议适配模块通过内部接口通知宽带业务模块进行PA或者PC操作。
步骤S210、宽带业务模块和MEDIASERVER交互完成PA或者PC操作，并通过内部接口通知窄带协议适配模块PA或者PC的结果，由窄带协议适配模块通过内部接口通知窄带业务模块。
步骤S211、窄带业务模块结束放音向窄带协议适配模块发送DFC(Disconnect Forward Connection，拆除前向连接)操作消息，窄带协议适配模块通过内部接口通知宽带协议适配模块，宽带协议适配模块调用内部接口把DFC操作消息发送给宽带业务模块。
实际应用中，宽带业务模块接收到DFC操作消息后，一方面要给MEDIASERVER发送BYE消息结束和MEDIASERVER之间的会话，同时还要给MSC发送CANCEL或者BYE消息，如果是以180或者183携带MEDIASERVER的SDP的，需要发CANCEL消息给MSC；如果是以200OK携带MEDIASERVER的SDP的，需要发BYE消息给MSC；此时MSC产生的SIP呼叫在完成PA或者PC后已经被释放。
本实施例的窄带业务放音IP化的方法，在MSC接收到携带窄带放音IP化的信息的ETC消息时，将ETC消息转化为会话初始协议SIP请求消息直接发送给SCP的宽带业务模块，无需独立IP放音，使用性能更高的宽带媒体服务器来播放窄带音。降低了系统的复杂度，增加了可维护性，从而能达到更快更好的响应客户的需求的目的，并且利用宽带的媒体服务器进行窄带放音，从硬件上避免了E1线的接入，实现了全网IP化。
在前述实施例的基础上，本文实施例三提供了另一种窄带业务放音IP化的方法，需要说明的是，本实施例中涉及的窄带协议适配器、宽带协议适配器、窄带业务模块及宽带业务模块均设置在同一个SCP中。请参阅图3，为该方法的信令图，包括：
步骤S301、MSC接收用户A发起的窄带呼叫请求之后，向SIU发送IDP消息。
步骤S302、SIU将IDP消息发送给CAMEL RA(窄带协议适配器)。
本步骤中，SIU通过内部的IDP消息触发CAMEL RA。
步骤S303、CAMEL RA通过内部消息触发窄带业务模块，窄带业务模块识别出该窄带呼叫请求需要进行IP化放音，向SIU发送ETC消息。
本步骤中，其中ETC中的路由码为PREFIX+SCPID+窄带关联ID，PREFIX为呼叫前缀，SCPID为SCP的识别码，窄带关联ID为本次窄带会话的窄带关联ID。
步骤S304、SIU把ETC消息透传给MSC。
步骤S305、MSC向SIP RA宽带协议适配器发送SIP INVITE消息。
在一实施方式中，当MSC收到ETC消息后，依据ETC消息中的特殊路由码PREFIX做分析处理，并发出SIP INVITE消息，其中INVITE消息中的被叫号码为PREFIX+SCPID+窄带关联ID(IDS)，并且该SIP INVITE消息配置为发送到SCP的SIP RA。
该SIP INVITE还携带媒体描述信息SDP1。
步骤S306、SIPRA回复100TRYING消息给MSC，并触发宽带业务模块的宽带放音业务。
该步骤中，100TRYING消息表示此INVITE消息已经收到。
步骤S307、宽带业务模块控制SIP RA依据INVITE中的窄带关联ID和本次呼叫的宽带会话ID做关联记录，并通知CAMEL RA进行内部宽带窄带会话号关联。
步骤S308、宽带业务模块控制SIP RA发送INVITE呼叫请求给MEDIASERVER，并携带入呼INVITE的媒体描述信息SDP1。
步骤S309、MEDIASERVER向SIP RA应答200OK消息并携带MEDIASERVER的媒体信息SDPMS。
步骤S310、SIP RA把MEDIASERVER的媒体信息SDPMS通过180消息或者183消息或者200OK消息带给MSC。
至步骤S310、MSC主叫和MEDIASERVER完成双向的媒体协商。
步骤S311、宽带业务模块通过SIP RA向CAMEL RA发现ARI(Assist Request Instructions，辅助请求指令)内部消息，CAMEL RA再向窄带业务通知ARI消息，通知 放音已经准备好了。
步骤S312、当窄带业务模块在收到ARI消息后，继续进行PA或PC操作，CAMEL RA收到窄带业务的PA或PC操作后，依据内部的记录，发现是IP化放音业务的操作，首先根据内部建立的关联关系找到SIP RA的会话，同时直接内部调用SIP RA的PA、PC操作。
步骤S313、SIP RA在收到CAMEL RA的PA或PC操作后，上报给宽带业务模块，宽带业务模块在调用SIP RA的宽带的PAPC接口向MEDIASERVER发送PA或PC操作消息，从而间接控制MEDIASERVER进行PA或者PC操作。
步骤S314、MEDIASERVER进行PA或者PC操作，在放音结束或者收到用户的按键输入后，上报PA或PC结果给SIP RA，由SIP RA再上报给宽带业务模块。
步骤S315、宽带业务模块调用CAMEL RA提供的内部接口告知CAMEL RA放音或收号的结果，而CAMEL RA在收到从SIP RA来的放音或收号结果后，再通知给窄带放音业务。
至此窄带放音业务就完成了从ETC链接放音设备到发送PA、PC放音指示，最后在收到放音结果的过程。实际应用中窄带业务不需要关注太多，就可以完成使用宽带的MEDIASERVER完成放音或收号，实现过程比较简单。
实际应用各种在一次会话过程中，窄带业务模块可以连续进行PA或者PC操作。
步骤S316、窄带放音业务在PA或者PC结束后，向SIP RA发送DFC消息切断和放音设备的联系。
在一实施方式中，CAMEL RA调用SIP RA的接口通知SIP RA要结束放音。
步骤S317、SIP RAD收到DFC消息后通报给宽带业务模块，宽带业务模块发送BYE消息切断和MEDIASERVER的链接。
步骤S318、宽带业务模块向MSC发送CANCEL或者BYE消息结束MSC的SIP会话。
本实施例的窄带业务放音IP化的方法，在MSC接收到携带窄带放音IP化的信息的ETC消息时，将ETC消息转化为会话初始协议SIP请求消息直接发送给SCP的宽带业务模块，无需独立IP放音，使用性能更高的宽带媒体服务器来播放窄带音。降低了系统的复杂度，增加了可维护性，从而能达到更快更好的响应客户的需求的目的，并且利用宽带的媒体服务器进行窄带放音，从硬件上避免了E1线的接入，实现了全网IP化。
