控制模块11，设置为控制MSC接续呼叫。在接收模块10接收该呼叫控制权后，控制模块11开始发送消息控制MSC接续该呼叫。所述控制模块11向所述MSC发送请求报告事件消息(Request Report BCSM Event，RRBE)、申请计费消息(Apply Charging，AC)和继续对话(CONTINUE)消息以控制所述MSC接续呼叫。在MSC接续呼叫的情况下，被叫用户的终端上显示的是一个未接来电的提示，提醒被叫用户回电。其中，所述发送请求报告事件消息的无应答时长可设置为1S，所述申请计费消息的时长可设置为1S。在该控制模块11控制MSC 接续呼叫前，控制模块11还可设置为控制互动式语音应答(Interactive Voice Response，IVR)给主叫用户发送放音信息，提示主叫用户余额不足或透支。
判断模块12，设置为在所述控制模块11控制所述MSC接续呼叫前，判断主叫用户是否符合呼叫使用条件；若所述主叫用户符合呼叫使用条件，则所述控制模块11控制MSC接续呼叫；若所述主叫用户不符合呼叫使用条件，则所述控制模块11还设置为释放呼叫。
所述呼叫使用条件包括主叫用户的目标业务处于激活状态，其中，目标业务设置为在主叫用户余额不足或透支的情况下，接续呼叫。即判断模块12通过查询业务数据库，根据主叫用户的信息表，判断主叫用户是否订购了目标业务，如果订购了目标业务，则表明目标业务处于激活状态。所述呼叫使用条件还可包括主叫用户使用目标业务的次数不大于预定义的最大使用次数，即如果主叫用户使用该目标业务的次数已经超过系统预定义的最大次数，则不允许主叫用户再使用该目标业务。
图2是本实施例一种呼叫处理方法的流程图。所述方法包括以下步骤。
在步骤20中，当主叫用户余额不足或透支时，呼叫处理装置接收SCP转发的呼叫控制权。当主叫用户发起呼叫时，OCS对主叫用户进行鉴权、批价、反算、预留等操作，在发现主叫用户的余额不足或者透支的情况下，向SCP返回特定的错误码4012，SCP通过IDP Reply消息将呼叫控制权转发给呼叫处理装置。
在步骤21中，呼叫处理装置控制MSC接续呼叫。在接收该呼叫控制权后，开始发送消息控制MSC接续该呼叫。所述控制模块11向所述MSC发送请求报告事件消息(Request Report BCSM Event，RRBE)、申请计费消息(Apply Charging，AC)和继续对话(CONTINUE)消息以控制所述MSC接续呼叫。其中，所述发送请求报告事件消息的无应答时长可设置为1S，所述申请计费消息的时长可设置 为1S。在MSC接续呼叫的情况下，被叫用户的终端上显示的是一个未接来电的提示，提醒被叫用户回电。在控制MSC接续呼叫前，还可控制互动式语音应答(Interactive Voice Response，IVR)给主叫用户发送放音信息，提示主叫用户余额不足或透支。
图3是本实施例另一种呼叫处理方法的流程图。所述方法包括以下步骤。
在步骤30中，当主叫用户余额不足或透支时，呼叫处理装置接收SCP转发的呼叫控制权。
在步骤31中，呼叫处理装置控制IVR给主叫用户放音提示主叫用户余额不足或透支。
在步骤32中，呼叫处理装置判断主叫用户是否符合呼叫使用条件。所述呼叫使用条件包括主叫用户的目标业务处于激活状态，其中，目标业务设置为在主叫用户余额不足或透支的情况下，接续呼叫。即判断模块12通过查询业务数据库，根据主叫用户的信息表，判断主叫用户是否订购了目标业务，如果订购了该项目标业务，则表明目标业务处于激活状态。所述呼叫使用条件还可包括主叫用户使用目标业务的次数不大于预定义的最大使用次数，即如果主叫用户使用目标业务的次数已经超过系统预定义的最大次数，则不允许主叫用户再使用该业务。
在步骤33中，若主叫用户符合呼叫使用条件，呼叫处理装置控制MSC接续呼叫，在MSC接续呼叫时，被叫用户的终端上显示的是一个未接来电的提示，提醒被叫用户回电。若主叫用户不符合呼叫使用条件，控制模块11释放该呼叫。
图4是本实施例一种呼叫处理方法的信令流程图，以说明呼叫处理方法的流程，包括以下步骤。
在步骤40中，主叫用户起呼，起呼消息被转发到MSC。
在步骤41中，MSC通过CAMEL协议的IDP消息将呼叫转发到SCP。
在步骤42中，SCP将相关信息通过初始信用控制请求消息(Credit Control Request，CCR initial)发送给OCS。
在步骤43中，OCS对SCP发送的信息对主叫用户进行鉴权、批价、反算、预留等操作时，发现主叫用户的余额不足或者透支时，根据Diameter协议，向SCP返回特定的错误码4012。
在步骤44中，SCP通过IDP Reply消息将呼叫控制权转发给呼叫处理装置。
在步骤45中，呼叫处理装置向MSC发送建立临时连接消息(Establish Temporary Connection，ETC)给MSC请求放音。
在步骤46和步骤47中，MSC与IVR进行ISDN用户部分协议(ISDN User Part)信令交互。
在步骤48中，IVR向呼叫处理装置发送帮助请求指令(Assist Request Instructions，ARI)消息。
在步骤49中，呼叫处理装置发送播放语音消息(Play Audio，PA)给主叫用户放音，提示主叫用户余额不足或透支。
在步骤50中，IVR向呼叫处理装置返回特殊资源报告消息(Specialized Resource Report，SRR)。
