图 5是采用 C P服务的主叫用户直接呼叫 CRP呼叫过程示意图； 图 6是采用 CRP服务的主叫用户通过消息向 CRP预约呼叫过程示意图。 具体实施方式
下面结合说明书附图来说明本发明的具体实施方式。
如图 2所示， 是本发明的 CRP的结构示意图， 从图中可以看到， CRP主要 包括以下几个部分：
话路和信令管理模块： 负责与其他网元的信令和话路连接，对话路和信令进 行管理。
呼叫接入控制模块： 用于控制呼叫接入； 包括负责接入主叫用户的呼叫， 存 储呼叫的相关信息到等待通话数据存储模块， 并请求消息处理模块向被叫发起 通知消息；被叫用户回呼后通过检索等待通话数据存储模块对比被叫识别号码， 和对应的等待中的主叫连接， 接通呼叫， 产生呼叫相关的统计信息和话单等。
消息处理模块： 其功能有： （1 ) 负责向被叫发起回呼通知， 通知消息内容 包含主叫号码和必要的通知信息； 以便用户识别主叫， 并能方便地回呼呼叫中 心； （2 )负责接收主叫用户发来的请求呼叫的消息， 分析消息内容， 存储主被 叫信息到等待通话数据存储模块， 并向被叫发出回呼通知。
等待通话数据存储模块： 与消息处理模块和呼叫接入控制模块连接，用于存 储等待通话的呼叫的相关信息， 包括主叫标识号码， 被叫标识号码， 等待计时 器等呼叫控制相关信息， 在呼叫接续成功或者接入等待时间超时后清除信息。
所述的话路和信令管理模块接收他网元的呼叫请求信令，并将其传送给呼叫 接入控制模块， 由呼叫接入控制模块存储呼叫的相关信息到等待通话数据存储 模块， 并请求消息处理模块向被叫发起通知消息， 由消息处理模块负责向被叫 发起回呼通知， 由呼叫接入控制模块完成呼叫接续。
上述的 CRP， 还包括一个终端输入设备， 与所述的消息处理模块相连接， 用 于设置回呼通知内容。
如图 3所示， 是本发明的 CRP, 在网络中的连接示意图， 从图中可以看出， CRP通过话路和信令与本地网络连接， 通过信令链路与消息服务处理系统， 如： 短消息中心， USSD中心等连接。 其中， 消息服务处理系统是指现网中对消息业 务进行控制处理的设备， 比如短消息中心， USSD中心等， 与电信网络和应用提 供设备直接联系， 一个消息传送到消息服务中心后经过控制处理可以传送到一 个应用或通过电信网络传送给另一用户。 一个用户发起的信息通过电信网络传 输到消息服务中心进行控制处理传送到目的地（一个应用或另一用户） ， 一个 应用也可以发起消息经过消息服务中心处理传送到某个用户。
如图 4所示， 是本发明 CRP内部功能模块与外部连接的示意图。
本发明对漫游用户呼叫的代理方法， 是依据上述的 CRP, 通过向 CRP发起 请求， 由 CRP通知漫游用户回呼漫游呼叫代理设备并接通主被叫， 从而使本次 呼叫的主被叫用户对于呼叫代理而言都是主叫 , 避免了漫游用户作被叫。
现假设有用户 B漫游至用户 A所在地， 现在用户 A欲和用户 B进行通话， 釆用本发明的对漫游用户呼叫的代理方法， 包括以下步骤：
a、 漫游地用户 A向 CR 提起漫游用户呼叫代理服务请求；
b、 CRP接到漫游地用户 A的该服务请求后，向被叫发起回呼请求信息信 息， 到给被叫提供服务的消息服务处理系统， 消息服务处理系统获得被叫的位 置信息后， 向被叫的提供服务的交换节点 VMSC/VLRB发送消息， 最终发送给 被叫用户 B;
c、 被叫用户： B接收到该消息后， 回呼 CRP;
d、 移动服务交换中心把该呼叫送到 CRP处理。 CRP接入 B的呼叫， 并 查询等待通话数据库， 把 A和 B话路接通。
在上述的步骤 b中，该回呼请求信息中， 包括对被叫用户拨打主叫用户所采 取方法的指示。
该指示可以包括以下几种情况， 由 CRP视情况而定：
直接拨打 CRP特服号码， 或特服号码 +特定指示号码， 或特服号码 +主叫号 码。 以上步骤中 a中，该漫游用户呼叫代理服务请求，可以通过多种方式来完成， 如由呼叫用户直接发起呼叫请求来完成， 也可通过发送呼叫预约消息的方式来 完成， 如果通过发送呼叫预约消息的方式， 则可以通过 USSD ( Unstructured Supplementary Service Data -非结构化补充业务数据） 方式或 SMS(Short Message Service -短消息)方式来完成。
以上步骤 d中， 如果没有主叫到 CRP的呼叫连接， 可以通过如下步骤建立 连接：
dl、 CRP 判断主叫是否可以选择直接呼叫， 如果是则直接呼叫主叫建立呼 叫连接， 否则进入步骤 d2;
d2、 CRP向主叫发送回呼请求信息；
d3、 主叫接收到该消息后， 回呼 CRP;
d4、 CRP接入主叫的呼叫， 建立呼叫连接。
如图 5所示， 是用户 A通过呼叫的方式与用户 B进行通话的示意图。 从图 中可以看到， 在实际的网络中， 与本发明方法相关的网絡节点包括： 交换节点 和 VMSC/VLRB。其中， 交换节点就是电信网络中完成信令和话路交换的设备，' VMSC/VLRB是给 B用户提供服务的移动服务交换节点 VMSC/VLR。
在本实施例中， 可以选择用户 A通过呼叫的方式提起请求， 这时该呼叫的 方式可以通过拨打呼叫代理特服号码 +被叫号码的方式来完成。如果被叫用户是 国际漫游用户拨号中的被叫号码， 则还需要在被叫号码之前加上国际拨号前缀 和被叫归属国家号。
如图 6所示， 是用户 B采用消息的方式向 C P发起请求， 与用户 A通话的 示意图， 从图中可以看出， 如果用户通过消息的方式向 CRP预约呼叫， 则该消 息的发送， 须经由消息服务处理系统向 CRP发送呼叫预约消息。
上述的等待通话数据存储模块中的相关数据，在呼叫接续成功或者接入等待 时间超时后清除。
本发明通过在现有的移动通信系统中， 引入 CRP，接入完成对漫游用户的呼 叫， 提供一种能对现有网络设备没有特殊要求， 能够避免到归属地路由迂回的 方法和设备，从而改善对漫游用户的呼叫质量并节约主被叫不必要的长途费用。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限 于此， 任何熟悉本技术领域的技术人员在本发明揭露的技术范围内， 可轻易想 到的变化或替换， 都应涵盖在本发明的保护范围之内。 因此， 本发明的保护范 围应该以权利要求书的保护范围为准。
