Description

一种实现呼叫管理的方法、 系统及业务控制点 本申请要求于 2008 年 08 月 13 日提交中国专利局、 申请号为 200810030152.0、发明名称为"一种实现呼叫管理的方法、 系统及业务控制点" 的中国专利申请的优先权， 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及通信技术领域， 尤其涉及一种实现呼叫管理的方法、 系统及 业务控制点。 背景技术
业务控制点（ Service Control Point , 简称： SCP )是目前通信网络中移动 智能网的核心， 加载有业务逻辑和用户的数据。 当一个移动智能网用户发起 呼叫或被呼叫时， 移动业务交换中心 /业务交换点 （ Mobile Service center/Service Switching Point,简称： MSC/SSP )给 SCP上报触发探测点（ Detect Point, 简称： DP ) /初始探测点 （Initinal Detect Point,简称： IDP)消息， 从而 启动 SCP上的移动智能业务， 其呼叫过程将由 SCP进行控制。 SCP控制呼叫 的基本过程是这样的： 呼叫触发到 SCP后， SCP启动智能业务逻辑， 进行基 本的呼叫处理（例如， 分析出主、被叫号码）； 查找用户的数据进行呼叫鉴权， 分析用户的帐户有效性； 判断本次呼叫有效后， 要求 MSC/SSP接续呼叫， 并 进行计费； 最后当终端的用户挂机后 SCP中的控制过程结束， 完成一次呼叫 的控制。
通信网络中， 每一个接入的终端都会有一个标识， 如接入全球移动通信 系统（GSM )、 公用电话网 （PSTN )、 码分多址复用 （CDMA )等网络都会有 一个号码， 这个号码在主叫端发起呼叫时会由通信网络传递到被叫端， 只要 被叫端的用户开通了来电号码显示功能， 就可以看到主叫端的号码。 以 GSM网络为例， 呼叫发生时， MSC将主叫端的呼叫请求发送到被叫 端所在网络， 被叫端所在网络将携带有主叫端号码的呼叫发送给被叫端， 被 叫端根据接收到的主叫端号码决定是否接听本次呼叫， 或者被叫端根据接收 到的主叫端号码从其存有的用户信息通讯录里查询主叫端的用户信息， 并根 据查询的结果决定是否接听本次呼叫。
当前， 由于被叫端只能接收一串数字信号， 无法携带更多的信息， 所以 对主叫端号码的识别都只能是在被叫端上进行处理。 然而， 当出现以下情况， 如： 1、 主叫端号码未曾通知过被叫端； 2、 终端的通讯录因容量有限无法记 录所有号码的信息 （例如一个集团有好几千人而终端上的通讯录往往只有一 百到两百个）； 3、 终端丟失导致终端中的通讯录丟失等等， 都将导致终端无 法显示足够的用户信息， 从而使被叫端的用户就很难判断是否应当接听本次 呼叫。
而现实生活中， 被叫端的用户只愿意有选择地接听电话的情况很多， 如 参加会议或重要工作时不想接听推销电话等， 都是有可能的。 而一般人能够 记忆的电话号码并不多， 也就常用的一些号码， 这么少的号码是无法应付当 前曰益增加的沟通需求的。 因此在很多情况下， 被叫端的用户都只能试探性 地接听电话然后很快挂掉， 但是这样已经打扰了正在进行的工作。 发明内容
本发明实施例提供一种实现呼叫管理的方法、 系统， 使得被叫端能够根 据主叫端的用户信息选择是否接听呼叫， 从而实现了对呼叫的管理。 本发明 实施例还提供了一种业务控制点， 用于为被叫端提供主叫端的用户信息。

本发明实施例在主叫端发起呼叫的情况下， 通过业务控制点的用户查询 模式查询得到主叫端的用户信息， 然后将该主叫端的用户信息被发送到被叫 端， 使得在被叫端处可以根据主叫端的用户信息选择是否接听呼叫， 从而实 现对呼叫进行管理。
图 1为本发明实施例一的实现呼叫管理的方法流程示意图。如图 1所示， 本发明实施例的实现呼叫管理的方法， 包括以下步骤：
S 11、 根据主叫端的呼叫请求消息查询到主叫端的用户信息；
此处， SCP提供主叫端的用户信息查询功能， 接收到主叫端的用户请求 消息后自动进行主叫端的用户信息查询。 所述主叫端的呼叫请求信息中包括 主叫端号码和被叫端号码， SCP可以根据已知的主叫端号码查询用户信息数 据库来获取主叫端的用户信息， 例如： 名称、 职位和归属地等； 也可以根据 主叫端号码和被叫端号码一起查询用户信息数据库来获取主叫端的用户信 息。 所述用户信息数据库可以是位于业务控制点上， 也可以是位于在业务控 制点以外的其他设备上。
512、 发送所述主叫端的用户信息到被叫端；
本实施例中， 可以通过短消息、 非结构化补充数据业务（Unstructured Supplementary Service Data, 简称： USSD ) 消息、 来电显示或交互式语音应 答（ Interactive Voice Response, 简称： IVR )呼叫等向被叫端发送主叫端的用 户信息。
513、 根据所述被叫端对带有所述主叫端的用户信息的呼叫做出的响应， 执行相应的呼叫控制。
本实施例中， 被叫端接收到主叫端的用户信息和本次呼叫， 当被叫端根 据主叫端的用户信息选择接听呼叫时， 则主叫端与被叫端之间建立起通话连 接， 当通话结束后， SCP的控制过程结束。 当被叫端根据主叫端的用户信息 选择拒绝接听呼叫时， 则 SCP指令切断本次呼叫。 当被叫端既不选择接听呼 叫， 也不选择拒绝接听呼叫 （例如用户不在通信终端旁）， 经过预先定义的一 段时间， 接收不到被叫端的响应消息时， 最终 SCP指令切断本次呼叫。
图 2为本发明实施例二的实现呼叫管理的方法流程示意图。如图 2所示， 所述方法包括以下步骤：
S21、 启动用户信息查询模式；
本实施例中，可以是预先在归属位置寄存器 HLR中设置终端的用户签约 信息 CSI。 当呼叫发生时， 移动业务交换中心 MSC会根据归属位置寄存器 HLR发送的用户签约信息 CSI触发 IDP消息，所述 IDP消息中包括用于 SCP 启动具体业务的业务键参数。 MSC将该 IDP消息发送到 SCP, SCP接收到 IDP 消息后， 根据所述业务键参数启动用户信息查询模式。
可选地， 本发明实施例还可以是在呼叫发生时， SCP根据被叫端在 HLR 的预先配置信息 (例如被叫端被呼叫时通知 SCP处理 )或在 SCP上的预先配 置信息， 来启动 SCP的用户查询模式。
上述启动用户查询模式的方法， 不仅可以应用在 GSM网络中的 CAMEL 协议中， 还可以运用在其他网络中， 如： PSTN网络、 CDMA网络、 IP多媒 体子系统（IP Mutimedia Subsystem, 简称： IMS ) 网络中， CDMA网络也有 HLR支持 CSI信息， IMS网络中有 SHLR支持 CSI信息。
S22、 根据主叫端的呼叫请求信息查询到主叫端的用户信息；
本实施例中，主叫端的呼叫请求信息包括主叫端的号码和被叫端的号码， SCP可以才艮据主叫端号码查询用户信息数据库来获得主叫端的用户信息， 例 如： 名称、 职位和归属地等； 也可以根据主叫端的号码和被叫端的号码一起 查询用户信息数据库来获取主叫端的用户信息。 所述用户信息数据库可以是 位于业务控制点上， 也可以是位于在业务控制点以外的其他设备上。
S23、 根据所述主叫端的用户信息和预先配置的所述被叫端的通信录和 / 或所述被叫端当前工作状态有选择地发送所述主叫端的用户信息。其具体为： 判断所述被叫端处理该主叫端呼叫的情况， 如果判断为所述被叫端不需 要接听， 则执行步骤 S24; 如果判断为所述被叫端当前必须接听， 则执行步 骤 S25; 否则执行步骤 S26;
S24、 所述业务控制点发送释放呼叫 Release call消息；
此处， 所述业务控制点发送释放呼叫消息到 MSC后， MSC切断本次呼 叫。
S25 、 所述业务控制点按照普通呼叫的方式发送连接 /接续 ( Connect/Continue ) 消息；
此处， MSC接收该 Conncet/Continue消息后， 将该呼叫发送给被叫端， 被叫端接收到的将是普通方式的带电话号码的来电显示的呼叫。
S26、 发送所述主叫端的用户信息到所述被叫端；
本发明实施例中， 发送所述主叫端的用户信息到所述被叫端， 可以通过 以下方式：
一、 发送携带有所述主叫端的用户信息的 USSD消息给所述被叫端。 其 中， USSD 消息中还包括供所述被叫端选择的菜单， 所述菜单的内容包括： 同意接听、 带背景音效的同意接听、 回复为忙的拒绝接听、 回复为号码不存 在的拒绝接听和回复为不在服务区的拒绝接听等等；
二、 发送携带有所述主叫端的用户信息的短消息给所述被叫端； 三、 发送携带有所述主叫端的来电显示到所述被叫端；
四、 发送携带有所述主叫端的用户信息的消息到交互式语音应答 IVR呼 叫中心， 所述 IVR呼叫中心根据上述消息生成内容包含所述主叫端的用户信 息的语音信息， 然后将所述语音信息发送给所述被叫端。 其中， SCP发送所 述主叫端的用户信息到 IVR呼叫中心的方式为： SCP与 IVR呼叫中心建立起 通信连接， SCP发送携带有所述主叫端的用户信息的消息到 IVR呼叫中心。
本发明实施例中， 根据主叫端的呼叫请求信息查询到所述主叫端的用户 信息， 发送所述主叫端的用户信息到所述被叫端的方式还可以是：
SCP发送 CONNECT消息给 MSC, MSC与 IVR呼叫中心建立连接。 此 处， SCP发送的 CONNECT消息里携带的被叫端号码为 "IVR呼叫中心号码 和原被叫端号码"， 主叫端号码不变。 然后 MSC根据该 CONNECT消息将呼 叫转给 IVR呼叫中心。所述 IVR呼叫中心可以从上述主叫端号码和被叫端号 码中得到所述主叫端号码和所述被叫端号码， IVR呼叫中心预先根据主叫端 号码和被叫端号码为被叫端配置好相应的语音信息， 此时根据接收到需要提 供主叫端用户信息的消息， 获取到相应的， 内容包含所述主叫端的用户信息 的语音信息， 然后 IVR呼叫中心将该语音信息发送给所述被叫端。
527、 所述被叫端根据接收到的所述主叫端的用户信息处置当前呼叫， 当 选择接听呼叫时， 则执行步骤 S28; 当选择拒绝接听呼叫时， 执行步骤 S29; 当既不选择接听呼叫， 也不选择拒绝呼叫时， 执行步骤 S30;
528、 建立通话连接；
此处， SCP接收到被叫端对本次呼叫做出的接听响应后，指令 MSC为主 叫端与被叫端建立起通话连接。
529、 切断本次呼叫；
此处， SCP接收到被叫端对本次呼叫做出的拒绝接听响应后， 指令 MSC 切断本次呼叫。
530、 经过预先定义的一段时间后， 切断本次呼叫；
此处， SCP经过一段时间没有接收到的任何响应，指令 MSC切断本次呼 叫。
最后， 通话结束后， 或者本次呼叫被切断后， SCP 的控制过程也相应地 结束。
本发明实施例通过只拓展 SCP上的业务， 就能够为被叫端提供主叫端的 用户信息， 从而被叫端能够根据获知的信息选择是否接听， 使得用户可以明 确地选择是否接听电话。，
图 3为根据图 2所示的方法被叫端选择接听的流程示意图。如图 3所示， 本实施例从主叫端发起呼叫， 然后经过网络， 最后被叫端根据主叫端的用户 信息选择接听呼叫时的流程如下：
5301、 主叫端的用户发起呼叫到 MSCa;
5302、 MSCa/SSP取被叫端的漫游号码，发送路由消息（ Send Routing Info , 简称： SRI )消息到归属位置寄存器（ Home Location Register, 简称： HLR );
S303、 HLR返回包含用户签约信息的 SRI确认消息到 MSCa/SSP;
此处，被叫端应有订购本业务， 因此在 HLR中有用户签约信息（ CAMEL Subscription Information , CSI )„
5304、 MSCa/SSP根据 CSI触发发送 IDP消息到 SCP;
5305、 SCP根据已知的主叫端和被叫端的号码， 通过查询数据库得到主 叫端的用户信息， 例如名称、 职位、 归属地等；
5306、 SCP通过 USSD消息向被叫端发送主叫端的用户信息， 并提供菜 单选择， 菜单选择包括的内容有： 同意接听、 同意接听（带背景音效）、 拒绝 接听（忙）、 拒绝接听（号码不存在）、 拒绝接听（不在服务区）；
5307、 被叫端根据看到的信息在菜单中选择接听， 该选择接听的消息被 传送到 SCP;
5308、 SCP下发连接 ( CONNECT ) 消息给 MSCa;
5309、 MSCa第二次向 HLR发送 SRI消息， 此时抑制 CSI;
5310、 HLR向 MSCa返回被叫端的漫游号码；
S311、 MSCa向 MSCb发送 IAM消息；
S312、 MSCb发送 ANM响应消息到 MSCa;
5313、 主叫端和被叫端正常通话；
5314、 主叫端挂断连接。
图 4为根据图 2所示的方法被叫端选择拒绝接听的流程示意图。 如图 4 所示， 本实施例从主叫端发起呼叫， 然后经过网络， 最后被叫端根据主叫端 的用户信息选择拒绝接听呼叫的流程如下：
S401、 主叫端的用户发起呼叫到 MSCa; 5402、 MSCa/SSP取被叫端的漫游号码，发送路由消息（ Send Routing Info , 以下简称： SRI )消息到归属位置寄存器（ Home Location Register,简称： HLR );
5403、 HLR返回包含用户签约信息的 SRI确认消息到 MSCa/SSP;
此处，被叫端应有订购本业务， 因此在 HLR中有用户签约信息（ CAMEL Subscription Information, 简称： CSI )。
5404、 MSCa/SSP根据 CSI触发发送 IDP消息到 SCP;
5405、 SCP根据已知的主叫端和被叫端的号码， 通过查询数据库得到主 叫端的用户信息， 例如名称、 职位、 归属地等；
5406、 SCP通过 USSD消息向被叫端发送主叫端的用户信息， 并提供菜 单选择， 菜单选择包括的内容有： 同意接听、 同意接听（带背景音效）、 拒绝 接听（忙）、 拒绝接听（号码不存在）、 拒绝接听（不在服务区）；
5407、 被叫端根据看到的信息在菜单中选择拒绝接听（不在服务区）， 该 拒绝接听的消息被传送到 SCP;
5408、 SCP下发播放通知 (Play Announcement, 简称： PA)消息给 MSCa, 向主叫端的用户播放语音 "您拨打的用户不在服务区"；
5409、 SCP向 MSCa下发释放呼叫 ( Release Call ) 消息， 从而切断本次 呼叫。
上述为被叫端提供主叫端的用户信息实现呼叫管理的方法， 能够运用在 非常普遍的场景下， 例如不希望对方知道自己的号码时， 可以选择拒绝接听 (号码不存在） 的菜单。 这种服务对运营商来说可提高终端用户的满意度。 的消息都为标准的消息， 因此对网络的兼容性 4艮好。
相应地， 本发明实施例还提供了一种实现呼叫管理的系统。 使用本系统， 主叫端向被叫端发起呼叫时， 被叫端能够根据接收到的主叫端的用户信息选 择是否接听本次呼叫。
