[32] 实施本发明的方式
[33] 为了使本领域的技术人员更好的理解本发明内容， 以下结合附图以及具体实施 例对本发明内容作具体说明。
[34] 本发明实施例的限制呼叫中心进行呼叫的方法的基本流程可参考图 1， 主要包 括步骤：
[35] Al、 接收主叫用户所在移动交换中心发送的请求消息， 确定所述请求消息中包 含的被叫用户处于漫游状态；
[36] 具体的确定所述请求消息中包含的被叫用户处于漫游状态的情况如下， 情况 1 ： 主叫用户向被叫用户发起呼叫， 呼叫路由到主叫用户所在的移动交换中心， 主叫用户所在的移动交换中心向被叫用户的归属位置寄存器 （Home Location Register , HLR) 发送路由发送信息 (Send Routing Number, SRI) ， HLR确定 被叫用户处于漫游状态， 如， 当主叫用户为呼叫中心吋， 呼叫中心 （CC， Call Center) 向被叫用户发起呼叫， 向关口移动交换中心 （Gate Mobile Switch Center
， GMSC) 发送初始地址信息 （Initial Address Message
， IAM) ， GMSC收到 IAM消息后， 向被叫用户的归属位置寄存器 HLR发送 SRI 信息， 被叫用户的 HLR收到 SRr消息后， 比较自身保存的本地拜访位置寄存器 V MSC/VLR设备信息与被叫用户当前拜访位置寄存器 VMSC/VLR设备信息， 及， 自身保存的归属位置寄存器 HLR设备信息与被叫用户当前拜访位置寄存器 VMSC /VLR设备信息， 确定所述移动用户处于漫游状态。
[37] 情况 2: 主叫用户向被叫用户发起呼叫， 呼叫路由到主叫用户所在的移动交换 中心， 主叫用户所在的移动交换中心向被叫用户的 HLR发送 SRI， HLR向主叫用 户所在的移动交换中心返回路由发送信息响应消息 SRI— ack， 该消息中携带被叫 拜访地的移动交换中心 （Visited Mobile Switch Center, VMSC) 地址和被叫的签 约信息， 主叫用户所在的移动交换中心向业务控制点 （Sendee Control Point, SCP) 发送初始检出点 （Initial Detect Point， IDP) 消息， SCP收到 IDP消息后， 通过比较 IDP消息中携带的被叫拜访地的移动交换中心 VMSC地址和被叫号码， 判断所述被叫用户处于漫游状态， 确定所述移动用户处于漫游状态
[38] A2、 获取限制所述主叫用户呼叫所述被叫用户的信息， 根据所述限制所述主叫 用户呼叫所述被叫用户的信息向所述主叫用户返回指示呼叫失败的响应消息， 以便所述主叫用户终止对所述被叫用户的呼叫。
[39] 这里获取限制所述主叫用户呼叫所述被叫用户的信息至少可以有两种方法， 1 、 限制所述主叫用户呼叫所述被叫用户的信息配置在业务决策设备中， 根据预 先配置的信息获得所述限制所述主叫用户呼叫所述被叫用户的信息； 2、 主叫用 户对被叫用户的呼叫中携带所述主叫用户呼叫所述被叫用户的信息， 业务决策 设备根据所述呼叫包含的指示信息， 获得所述限制所述主叫用户呼叫所述被叫 用户的信息。 [40] 如， 当主叫用户为呼叫中心吋， 这里可以至少分两种情况：
[41] 第一种情况： CC向 GMSC发送得 IAM消息中包含限制呼叫中心呼叫被叫用户的 指示信息"如果被叫用户处于漫游状态， 则停止呼叫"， GMSC收到 IAM消息后， 向 HLR发送得 SRr消息中也包含限制呼叫中心呼叫被叫用户的指示信息"如果被 叫用户处于漫游状态， 则停止呼叫"， HLR响应 SRr消息， 确认被叫用户处于漫 游状态后， 向 GMSC发送呼叫失败响应消息 SRI_Ack指示呼叫失败， GMSC收到 S RI_Ack后， 向 CC发送地址全消息 （Address Complete Message， ACM) 信息指 示呼叫失败， 或，
[42] CC向 GMSC发送得 IAM消息中包含限制呼叫中心呼叫被叫用户的指示信息"如 果被叫用户处于漫游状态， 则停止呼叫"， GMSC收到 IAM消息后， 向 HLR发送 得 SRr消息中也包含限制呼叫中心呼叫被叫用户的指示信息"如果被叫用户处于 漫游状态， 则停止呼叫"， HLR响应 SRr消息， 向 GMSC发送 SRI_Ack消息， 该消 息中指示信息 "如果被叫用户处于漫游状态， 则停止呼叫"， GMSC收到 SRI_Ack 消息后， 向 SCP发送 IDP消息， IDP消息包含指示信息"如果被叫用户处于漫游状 态， 则停止呼叫"指示呼叫失败， SCP收到 IDP消息后， 向 GMSC发送连接消息指 示呼叫失败， GMSC向 CC发送 ACM信息指示呼叫失败。
[43] 第二种情况： HLR在收到 SRr消息， 确认被叫用户处于漫游状态后， 根据预先 设置的限制呼叫中心呼叫被叫用户的指示信息， 如， "当主叫用户为 10086， 被叫 用户处于漫游状态， 停止呼叫"， 由于已经确认被叫用户处于漫游状态， 当确认 主叫用户为 10086吋， HLR向 GMSC发送呼叫失败响应消息 SRI_Ack指示呼叫失 败， GMSC收到 SRI_Ack后， 向 CC发送 ACM信息指示呼叫失败， 或，
[44] SCP在收到 IDP消息， 确认被叫用户处于漫游状态后， 根据预先设置的限制呼 叫中心呼叫被叫用户的指示信息， 如， "当主叫用户为 10086， 被叫用户处于漫游 状态， 停止呼叫"， 由于已经确认被叫用户处于漫游状态， 当确认主叫用户为 100 86吋， SCP向 GMSC发送连接消息指示呼叫失败， GMSC向 CC发送 ACM信息指 示呼叫失败。
[45] 较佳地， 在呼叫失败响应消息中携带错误值， 如"用户处于漫游状态"， 以便 CC 通过短信， E— Mail等方式向被叫用户传递信息。 [46] 本发明实施例的限制呼叫中心进行呼叫的方法的基本流程可参考图 2， 主要包 括步骤：
[47] Bl、 接收主叫用户发送的査询请求， 所述査询请求用于査询移动用户是否处于 漫游状态；
[48] 如当主叫用户为呼叫中心吋， CC通过向 HLR发送査询信息， 这里的査询消息 可以为： 在 29.002协议中， MAP-SEND-ROUTING-INFO-FOR-CC接口消息， 如 下图所示， 用于 CC向 HLR査询该用户是否处于漫游状态。
[49] MAP-SEND-ROUTING-INFO-FOR-CC
[50]

[51] 同吋， CC向 HLR发送的査询信息中携带用户号码。
[52] B2、 确定所述移动用户处于漫游状态， 并向所述主叫用户返回査询响应信息以 确认所述移动用户处于漫游状态， 以使所述主叫用户根据返回的确认信息终止 对所述用户的呼叫。
[53] HLR在接收到査询消息后， 通过将本地配置的拜访地的移动交换中心 /拜访位 置寄存器 VMSC/VLR的设备信息或 HLR设备信息与本地保存的被叫用户拜访地 的移动交换中心 /拜访位置寄存器 VMSC/VLR的设备信息进行比较， 确定被叫用 户处于漫游状态， 接下来， 向 CC发送査询确认信息， 该确认信息中包含被叫用 户处于漫游状态的信息。
[54] 优选的， CC在收到査询确认消息后， 确认被叫用户处于漫游状态后， 通过短 信， E— Mail等方式向被叫用户传递信息。
