Description

过滤恶意呼叫完成指示的方法及装置、 主叫侧网络设备 技术领域
本发明涉及遇忙回叫业务 （ CCBS , Completion of Call to Busy Subscriber )处理技术， 尤其涉及一种遇忙回叫业务中过滤恶意呼叫完成指 示的方法及装置， 以及主叫侧网络设备。 背景技术
图 1为现有遇忙回叫业务的流程图， 如图 1所示， 现有的遇忙回叫业 务流程包括以下步骤：
步聚 1 , 主叫用户 A呼叫被叫用户 B, 被叫用户 B由于忙线而拒绝主 叫用户 A的呼叫请求；
步骤 2, 主叫侧应用服务器 （AS, Application Server ) O— AS向被叫侧 应用服务器 T— AS发送订阅消息（ SUBSCRIBE ) ,订阅被叫用户的空闲状态； 步骤 3 , T AS接收到 0— AS发送的 SUBSCRIBE后 ,返回 202OK消息 , 向 0— AS确认接收到 SUBSCRIBE。
步骤 3之后， 被叫侧应用服务器 T— AS对被叫用户 B开始进行忙状态 监管 （busy state supervision begin ), 当检测到被叫用户 B当前状态变为可 用 （ user B become available ) 时， 执行步骤 4。
步骤 4, 当被叫用户空闲， 被叫侧应用服务器 T— AS遍历订阅该用户空 闲状态的主叫侧 AS 列表， 向当前第一个订阅的主叫 AS 发送通知消息 ( NOTIFY );
步骤 5 , 主叫侧应用服务器 0— AS接收到 NOTIFY后， 向被叫侧应用 服务器 T— AS返回 200OK确认消息。
步骤 6至步骤 10,主叫侧应用服务器 0 AS釆用 REFER的方式通知主 叫用户 A发起回呼的呼叫请求 （INVITE ), 并由主叫侧应用服务器 0— AS 在主叫用户 A 的呼叫请求中添加呼叫完成指示 （ Completion of Call Indicator M言息；或者主叫侧应用服务器 0— AS发送第三方呼叫控制（ 3PCC, 3rd Party Call Control ) 流程， 向被叫用户 B发送呼叫请求 （INVITE ), 并 由主叫侧应用服务器 0— AS在呼叫请求中添加呼叫完成指示信息；
被叫侧应用服务器 T— AS接收到呼叫请求（ INVITE )后， 判断呼叫请 求（INVITE )是否携带有呼叫完成指示信息， 如果携带有呼叫完成指示， 被叫侧应用服务器 T— AS将该呼叫请求转发到被叫用户 B;如果未携带呼叫 完成指示， 则被叫侧应用服务器 T— AS使用 486 ( Busy Here )失败响应来拒 绝当前呼叫请求；
如果被叫侧应用服务器 T— AS 允许本次呼叫， 则会继续后续的处理流 程， 完成本次呼叫。
图 2为在图 1的基础上进行恶意呼叫的流程图， 如图 2所示， 恶意呼 叫的用户进行恶意呼叫的方式具体为：
步骤 1至步骤 5与图 1所示的步骤 1至步骤 5的处理方式完全相同， 这里不再赘述其实现细节。
步骤 6,恶意用户向被叫侧应用服务器 T— AS发送呼叫请求（ INVITE ), 该恶意用户在自身发起的呼叫请求中自行插入有呼叫完成指示信息。 被叫 侧应用服务器 T— AS将会按前述步骤 1至步骤 5所示的主叫用户 A的情形 来处理该恶意用户的呼叫， 即将当前恶意用户的呼叫请求作为遇忙回叫业 务的用户。
步骤 7,被叫侧应用服务器 T— AS将向被叫用户 B转发恶意用户的呼叫 请求， 而进行呼叫接入。
这样， 恶意用户反而优先用户 A与被叫用户 B实现呼叫接入。
步骤 8至步骤 12与图 1所示的处理流程相对应， 不再——赘述其实现 细节。
由图 2可知， 如果存在恶意用户在呼叫请求中自行添加呼叫完成指示， 主叫侧网络设备并不会对其进行过滤处理， 会让恶意用户的携带呼叫完成 指示信息的呼叫请求（INVITE )发送到被叫侧应用服务器 T— AS而建立呼 叫。 这样， 先发起订阅的主叫用户并不能先完成呼叫， 而是被后发起订阅。 这样， 恶意用户相当于实现了插队。 显然， 这非常不利于呼叫公平性， 严 重时还会影响正常用户的正常呼叫。 发明内容

图 6为本发明遇忙回叫业务中过滤恶意呼叫完成指示的方法实施例四 的流程图， 如图 6所示， 本示例中， 在主叫侧网络设备中设置呼叫完成指 示的检测方式， 当检测到呼叫请求中携带有呼叫完成指示时， 将在呼叫请 求中删除该呼叫完成指示， 再转发该呼叫请求， 也就是说， 本示例允许主 叫用户 A携带呼叫完成指示的呼叫请求进行呼叫接入， 但要将其中的呼叫 完成指示完全过滤掉。 本示例有具体包括以下步骤：
步骤 1 , 主叫用户 A向 P-CSCF/ MGCF/ AGCF发起呼叫请求， 该呼叫 请求中携带有呼叫完成指示。
步骤 2, 接收到主叫用户 A呼叫请求后， P-CSCF/ MGCF/ AGCF对所 接收到的呼叫请求进行检测， 判断该呼叫请求中是否携带有呼叫完成指示 信息， 当前确定呼叫请求中携带有呼叫完成指示， 删除该呼叫请求中的呼 叫完成指示， 再转发该呼叫请求。
本领域技术人员应当理解，当图 6所示的检测机制设置于 S-CSCF或主 叫侧应用服务器 0— AS等网络设备中时， 同样可以实现本发明的技术方案， 鉴于与图 4及图 5所示方式基本雷同， 这里不再一一赘述其实现细节。
图 7为本发明遇忙回叫业务中过滤恶意呼叫完成指示的装置的一种组 成结构示意图， 如图 7 所示， 本示例遇忙回叫业务中过滤恶意呼叫完成指 示的装置包括接收单元 70、 检测单元 71和拒绝单元 72; 其中：
接收单元 70 , 用于接收呼叫请求；
检测单元 71 , 用于对所述呼叫请求进行检测， 确定所述呼叫请求中携 带有呼叫完成指示信息时触发拒绝单元 72; 这里， 检测手段包括对呼叫请 求进行解析， 确定其中是否包含呼叫完成指示信息； 或者， 对呼叫请求中 的呼叫完成指示的对应字段进行检测， 当呼叫请求包含该字段时， 说明呼 叫请求中包含呼叫完成指示。
拒绝单元 72, 用于拒绝当前的呼叫请求。 拒绝单元将拒绝将当前的呼 叫请求转发给下一级网元。
图 8为本发明遇忙回叫业务中过滤恶意呼叫完成指示的装置的另一种 组成结构示意图， 如图 8所示， 本示例遇忙回叫业务中过滤恶意呼叫完成 指示的装置包括接收单元 80、 检测单元 81、 去除单元 82和转发单元 83; 其中： 接收单元 80 , 用于接收呼叫请求；
检测单元 81 , 用于对所述呼叫请求进行检测， 确定所述呼叫请求中携 带有呼叫完成指示信息时触发去除单元 82; 这里， 检测手段包括对呼叫请 求进行解析， 确定其中是否包含呼叫完成指示信息； 或者， 对呼叫请求中 的呼叫完成指示的对应字段进行检测， 当呼叫请求包含该字段时， 说明呼 叫请求中包含呼叫完成指示。
去除单元 82, 用于去除所述呼叫请求中的呼叫完成指示信息； 即将呼 叫请求中对应的呼叫完成指示信息删除， 再通过转发单元 83转发该去除呼 叫完成指示的呼叫请求。
转发单元 83 , 用于转发将去除单元 82处理后的呼叫请求。
本领域技术人员应当理解， 图 7及图 8所示的遇忙回叫业务中过滤恶 意呼叫完成指示的装置是为实现前述的遇忙回叫业务中过滤恶意呼叫完成 指示的方法而设置的， 图 7及图 8所示的装置中各处理单元的功能可参照 前述方法的描述而理解， 各处理单元的功能可通过运行于处理器上的程序 而实现， 也可通过具体的逻辑电路而实现。
本发明的主叫侧网络设备， 如 S-CSCF、 P-CSCF、 MGCF、 AGCF 或 AS, 包含有图 7或图 8所示的装置。
以上所述， 仅为本发明的较佳实施例而已， 并非用于限定本发明的保 护范围。
