Description

一种数字集群系统中对预付费用户进行寻呼控制的方法 技术领域 本发明涉及集群通信领域，尤其涉及一种数字集群系统中对预付费用户 进行寻呼控制的方法。 背景技术 集群通信系统是一种高级移动调度系统，具有可用信道为系统的全体用 户共用、 自动选择信道的功能， 是共享资源、 分担费用、 共用信道设备及服 务的多用途、 高效能的无线调度通信系统。 图 1是数字集群通信系统的基本网络框架图， 包括终端 1、 基站子系统 ( Base Station System , BSS ) 2、 集群调度子系统 3和业务控制点（ SCP ) 4 , 其中： 终端通过空中接口和集群系统相连，为用户提供集群系统的各种集群业 务； 同时兼具提供传统的普通语音业务、 补充业务、 短消息业务和数据业务 的功能。 BSS包括基站收发信机（ BTS )、基站控制器（ BSC；)和调度客户端（ PDC )
(基站控制器和网络侧交互的调度客户端对外是一个统一的功能实体 ), BSS 完成终端的接入功能， 并 居用户使用的业务类型将其派发到相应的子系统 处理。 集群调度子系统由调度服务器 （PDS ) 和预付费客户端 （PPC )、 调度 归属寄存器 （PHR ) 和预付费服务器 （PPS )、 调度台服务器 （DAS )、 调度 台客户端 （DAC )和受理台 （PHR Agent )组成， 调度子系统主要完成集群 调度业务。
PDS是集群呼叫的总控制点， 完成集群调度呼叫的处理等； PDS还接 收来自反向链路的集群语音数据，根据呼叫的性质再分发到对应的前向链路； PDS可以作为 PPC , 向 PPS报告用户的预付费能力， 负责用户配额申请， 监 控配额使用情况， 也可以使用的单独的设备作为 PPC。 PHR保存集群用户和群组的注册信息和位置信息， 实现对集群用户的 鉴权、 授权和计费， 以及位置更新和群组管理功能； PHR可以作为 PPS, 负 责向业务控制点 （ SCP )请求鉴别预付费用户账户状态， 并根据 PPC的预付 费能力选择本次会话使用的预付费方案，也可以使用的单独的设备作为 PPS。 DAS 负责维护各调度台、 管理台的会话， 实现管理台和调度台对集群 调度的管理和维护。
DAC 包括调度台与管理台， 调度台实现包括发起呼叫， 查询状态， 录 音等功能； 管理台进行对组的划分， 用户权限等管理操作。
PHR Agent可直接对集团、 组和用户进行管理， 如分配权限等。 SCP4负责保存预付费用户账户信息和费率切换信息， 具备费率换算功 能， 可以根据集群业务类型设置不同的汇率。 目前，通信领域已有的预付费业务中，对于预付费用户发起的呼叫， PHR 鉴权成功后， PDS直接把用户的呼叫上报给 SCP , SCP判断用户是否还有余 额， 然后才艮据余额申请的结果判断是否寻呼用户， 专利 CN200610160609和 US6044247中涉及到的预付费用户呼叫机制都是这种实现方式， 这种方式大 大影响了用户的接入速度。 发明内容 本发明要解决的技术问题是，针对现有技术中数字集群系统的预付费用 户呼叫接入速度慢的缺点， 提供了一种数字集群系统中对预付费用户进行寻 呼控制的方法， 该方法可有效提高预付费呼叫的接入速度。 本发明所述数字集群系统中对预付费用户进行寻呼控制的方法，数字集 群系统中包括 PDS、 PHR、 SCP , 集群预付费用户发起呼叫， PDS收到呼叫 后向 PHR发起呼叫鉴权请求，鉴权成功后， PHR向 PDS返回授权信息， PDS 收到授权信息后， 系统执行如下步骤： 步骤 1 : PDS首先判断该预付费用户的账户是否有余额， 若判断结果为 是， 则同时执行步驟 2和步骤 3 , 若判断结果为否， 则执行步驟 3 ; 步骤 2: PDS为该预付费用户发起寻呼； 步骤 3 : PDS向 PHR发送预付费情求； 步驟 4: PHR收到 PDS的预付费请求后， 向 SCP发起为预付费用户申 请配额请求； 步驟 5: SCP执行相应的业务操作， 并将结果返回给 PHR; 步驟 6: 若 SCP返回申请配额成功 , 贝' j PHR通知 PDS继续为该预付费 用户正常接续， 若 SCP送回申请配额失败， 则 PHR通知 PDS禁止该预付费 用户接人呼叫； 步骤 7: 该预付费用户呼叫结束； 步骤 8: PHR更新该预付费用户的账户信息并通知 PDS。 所述 SCP执行相应的业务操作包括负责检查该用户账号是否有合法的 状态及余额， 若检测结果为是， 则为该预付费用户分配配额， 同时将申请配 额成功消息返回给 PHR; 若检查结果为否， 则直接将申请配额失败消息返回 给 PHR。 所述 SCP返回申请配额失败时， 若系统已经执行所述步骤 2而持续为 该预付费用户发起寻呼 , 则 PDS停止寻呼该预付费用户。 所述 SCP返回申请配额失败时， 若系统已经响应所述步骤 2而使该预 付费用户接入呼叫， 则 PDS强制释放该预付费用户。 所述步驟 8还进一步包括 PDS更新该预付费用户的账户信息。 本发明所述的方法将集群预付费用户的寻呼点提前，有效地提高预付费 呼叫的接入速度， 适用于数字集群通信系统， 但不局限于集群系统。 附图说明 图 1 是数字集群通信系统的基本网络框架图； 图 2 是本发明所述方法流程示意图。 具体实施方式 下面结合附图对本发明作进一步详细的说明。 图 2 是本发明中所述对预付费用户进行寻呼控制的方法流程示意图， 包括以下步驟： 步骤 201 , 集群预付费用户向 PDS发送呼叫请求； 步骤 202 , PDS收到呼叫请求后向 PHR发起呼叫答权请求， PHR对呼 叫进行鉴权， 如果鉴权成功， 贝' j PHR向 PDS返回授权信息， 否则， 呼叫失 败， 流程结束； 步骤 203 , PDS判断该预付费用户账户是否有余额， 若判断结果为是， 则同时执行步驟 204和步骤 205 , 若判断结果为否， 则仅执行步 205; 步骤 204 , PDS为该预付费用户发起寻呼； 步骤 205 , PDS向 PHR发送预付费请求； 步骤 206, PHR收到 PDS发送的预付费请求后， 向 SCP发起为预付费 用户申倚配额倩求； 步驟 207， SCP检查该用户账号是否有合法的状态及余额， 若检测结果 为是， 则为该预付费用户分配配额， 同时将申请配额成功消息返回给 PHR; 若检测结果为否， 则直接将申请配额失败消息返回给 PHR; 步骤 208,若 PHR返回申请配额成功，则呼叫正常进行， PHR通知 PDS 继续为该预付费用户正常接续， 然后转入步骤 210; 步骤 209, 若 PHR返回申请配额失败， 则 PHR通知 PDS禁止该预付费 用户接入呼叫； 若由于系统已经执行步骤 204而持续向该预付费用户发起寻 呼， 则 PDS停止寻呼该预付费用户； 若系统已经响应步驟 204而使该预付费 用户接入呼叫， 则 PDS强制释放该预付费用户； 步骤 210, 该预付费用户呼叫结束； 步 211 , PHR根据 SCP申请配额的情况以及用户的欠费情况， 更新 该预付费用户的账户信息， 并通知 PDS更新对应的信息。 以上所述仅为本发明的优选实施例而已， 并不用于限制本发明，对于本 领域的技术人员来说， 本发明可以有各种更改和变化。 凡在本发明的精神和 原则之内， 所作的任何修改、 等同替换、 改进等， 均应包含在本发明的保护 范围之内。
