Description

一种过滤垃圾电话的方法、 装置、 代理服务器及终端 本申请要求了 2008年 10月 27日提交的, 申请号为 200810217106.1 , 发 明名称为 "一种过滤垃圾电话的方法、 装置、 代理服务器及终端" 的中国申 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, 特别涉及一种过滤垃圾电话的方法、 装置、 代理服务器及终端。
背景技术
随着 IP 网络通信业务的不断发展, 网络安全成为了一个值得关注的问 题。 除了传统的非法用户攻击外, IP 网络还受到了其他安全问题的困扰, 其 中, 一种重要的安全问题就是垃圾电话 (SPIT ) 的问题。 垃圾电话是在正常 的信令和媒体交互过程中产生的, 其目的并不是要对网络构成威胁, 其威胁 主要来自于其传送的内容造成了对被叫用户的打扰。 比如, 由于目前 ip 电 话(VoIP )具有话费低廉和终端设^更宜等诸多优点, 因此, 许多垃圾电话, 比如大量的广告和传销等电话, 便在 IP 网络中泛滥, 垃圾电话制造者为了 追求某种利益, 向大量的被叫用户终端发起垃圾电话呼叫, 被叫用户终端接 听了此种垃圾电话后, 则会听到诸如广告和传销等各种其不关心的垃圾内容, 因此, 对用户产生了 4艮大的干扰。 与此同时, 带有回拨吸费性质的垃圾电话 也逐渐开始泛滥。 此处, 垃圾电话为由机器或软件进行呼叫操作的电话。
从用户的角度来讲, 一方面由于每次垃圾电话制造者发出的呼叫, 无论 被呼叫者是否接听, 被呼叫者的注意力都会从其他事情上转移到处理垃圾电 话上来。
从运营商的角度讲, 首先, 如果垃圾电话制造者泛滥造成正常的 VoIP用 户的大量流失, 运营商将会得不偿失。 其次, 各个运营商之间的竟争关系, 若要自身利益最大化, 必须要提升自己服务水平, 严格控制本域内的垃圾电 话发起者, 才能吸引更多 VoIP用户。 最后, 本域内过多的垃圾电话制造者会 导致遭到其他运营商的封杀, 从而被隔离不能和其他运营商网络互通。 如果 垃圾电话制造者在网络中泛滥的话, 将给运营商带来无穷的危害, 名誉和商 业利润的损失, 严重的情况下会造成运营商的倒闭。 因此, 运营商基于自身 品牌及服务性考虑, 必然也必须会严格控制 SPIT攻击, 有效遏制垃圾电话发 起者的企图。 一方面能够严格的检测本运营域内的垃圾电话发起者, 另一方 面能够有效的阻止对本域内用户进行的垃圾呼叫。
目前现有的过滤垃圾电话的方法为基于语音识别系统的图灵测试方法, 该方法是以语音为基础的, 在服务器在收到某个主叫方的呼叫请求后, 并不 立即与被叫方建立呼叫连接, 而是向主叫方发送一段语音, 这段语音包含了 一个简单的逻辑问题; 主叫方在接听到问题后也会以语音的形式进行回答; 主叫方语音回答后, 通过安装在服务器端的语音识别系统识别后, 将答案进 行匹配, 如果匹配正确, 则允许与被叫方建立呼叫连接; 否则终止此次呼叫。
发明人在实现本发明的过程中, 发现现有技术至少存在以下缺点: 现有技术的语音识别系统对由机器或软件作为主叫方的回答进行语音识 别的准确率 4艮低; 服务器须安装语音识别系统, 而语音识别系统的成本 4艮高, 需要耗费较多的财力来实现。

在本实施例一中, 检测装置 21包括测试数据库 210和检测模块 212。 测试 数据库 210用于存储以验证码与智能回答相结合的方式或语音提问的方式生 成的测试信息及该测试信息对应的答案信息。 检测模块 212用于从测试数据库 210获取测试信息,并判断该测试信息对应的反馈信息是否正确。若判断正确, 则通过网络 30向被叫终端 40发送该呼叫请求。 若判断不正确, 则过滤该呼叫 请求, 即该呼叫请求的电话为垃圾电话, 需阻止该呼叫请求。 在本实施例一 中, 判断该测试信息对应的反馈信息是否正确时, 通过将该反馈信息与测试 数据库 210中存储的与该测试信息对应的答案信息进行匹配, 若匹配成功, 即 判断所述呼叫终端发送的所述测试信息对应的反馈信息正确, 判断呼叫终端 10发送的呼叫请求是由用户进行呼叫操作; 若匹配不成功, 即判断所述呼叫 终端发送的所述测试信息对应的反馈信息不正确, 判断呼叫终端 1 0发送的呼 叫请求是由机器或软件进行呼叫操作的垃圾电话的呼叫请求,即垃圾电话制 造者。
在本实施例一中, 验证码与智能回答相结合的方式生成的测试信息如图 2 所示。 该测试消息是一张验证码和智能问答相结合的图片。 这种图片对于机 器来说, 其做出正确回答的概率几乎可以为零。 在本实施例一中, 通过验证 码和智能问答相结合而得出的图片可以是多种, 图 2只是作一个更好的解释。 语音提问的方式生成的测试信息诸如 "某人有一个苹果, 又买了两个苹果之 后, 该人总共有几个苹果" 之类的问题, 若需要增加其安全性, 则问题可以 复杂化。 呼叫终端 10通过一键回答的方式反馈该测试信息中的答案。 一键回 答的方式为用户在呼叫终端 1 0上进行一次按键操作来回答呼叫终端 10所接收 的测试信息。 当用户完成一次按键操作后, 呼叫终端 10就会返回针对该测试 信息的反馈信息。
图 3为本发明实施例一的过滤垃圾电话的方法的流程图。 在本实施例一 中, 步骤 100 , 呼叫终端发起呼叫请求;
步骤 102 , 代理服务器接收该呼叫请求, 通过验证码与智能回答相结合的 方式或语音提问的方式生成测试信息, 并发送该测试信息至呼叫终端;
步骤 104 , 呼叫终端通过一键回答的方式发送该测试信息对应的反馈信 息, 所述反馈信息即呼叫终端反馈的针对所述测试信息的答案。 一键回答的 方式为用户在呼叫终端上进行一次按键操作来回答呼叫终端所接收的测试信 息。 当用户完成一次按键操作后, 呼叫终端就会返回针对该测试信息的反馈 信息。
步骤 106 , 代理服务器判断呼叫终端的反馈信息是否正确。 在本实施例一 中, 查询该反馈信息对应的测试信息的答案信息, 并将该反馈信息与答案信 息进行匹配, 若匹配成功, 判断呼叫终端的发送的呼叫请求是由用户进行呼 叫操作; 若匹配不成功, 即所述呼叫终端发送的所述测试信息对应的反馈信 息不正确, 判断呼叫终端发送的呼叫请求是由机器或软件进行呼叫操作的垃 圾电话的呼叫请求。
若正确, 则进入步骤 108 , 代理服务器通过网络向被叫终端发起该呼叫请 求;
若不正确, 则进入步骤 110, 过滤该呼叫请求, 即该呼叫请求的电话为垃 圾电话, 需阻止该呼叫请求。
本发明实施例一提供的过滤垃圾电话的方法、 检测装置及代理服务器, 将验证码与智能回答相结合的方式或语音提问的方式生成测试信息发送至呼 叫终端, 并判断呼叫终端通过一键回答的方式返回的反馈信息是否正确, 可 以很好的区分呼叫终端的呼叫请求是否为由机器或软件进行呼叫操作的垃圾 电话的呼叫请求, 可提高测试的安全性和准确性, 并且测试信息易于生成和 传输; 同时, 通过一键回答的方式来反馈信息, 使用户不必输入长串的验证 码, 因此, 可使用户操作简单, 方便易行; 此外, 验证码与智能回答相结合 的方式或语音提问的方式生成测试信息和通过一键回答的方式来反馈信息, 使检测设备无须安装语音识别系统, 从而达到减少成本的开销。
图 4为本发明实施例二的检测装置的应用环境图。
实施例二与实施例一的区别在于, 实施例二中没有代理服务器, 而检测 装置设置于呼叫终端或被叫终端。 被叫终端直接对呼叫终端发起的呼叫请求 进行检测。
在本实施例二中, 被叫终端 40包括检测装置 41、 收发装置 42、 电话接入 装置 43及提示装置 44。 在本实施例二中, 呼叫终端 10通过网络 30与被叫终端 40建立通信连接。 当呼叫终端 10向被叫终端 40发起呼叫请求时, 被叫终端 40 中的检测装置 41接收该呼叫请求, 通过验证码与智能回答相结合的方式或语 音提问的方式生成测试信息, 并通过收发装置 42发送至呼叫终端 10。 收发装 置 42还用于接收呼叫终端 10发送的反馈信息, 该反馈信息对应于所述测试信 息。 检测装置 41还用于判断该反馈信息是否正确。 在本实施例二中, 检测装 置 41与实施例一中的检测装置 21具有相同的结构和功能, 此处不再重复描述。 在本实施例二中, 网络 30可以为 VoIP网络, PSTN, GSM, WCDMA, TD-SCDMA。 呼叫终端 10和被叫终端 40可以为手机、 智能终端。
电话接入装置 43用于当检测装置 41判断该反馈信息正确时, 接入该呼叫 请求。 提示装置 44用于当接入该呼叫请求后, 显示该呼叫请求对应的呼叫终 端 10的电话号码或通知用户有电话呼叫; 若当检测装置 41判断该反馈信息不 正确时, 过滤该呼叫请求, 即该呼叫请求的电话为由机器或软件进行呼叫操 作的垃圾电话, 需阻止该呼叫请求。
图 5为本发明实施例二的过滤垃圾电话的方法的流程图。
步骤 200, 呼叫终端发起呼叫请求;
步骤 202 , 被叫终端接收该呼叫请求, 通过验证码与智能回答相结合的方 式或语音提问的方式生成测试信息, 并发送该测试信息至呼叫终端。
步骤 204 , 呼叫终端通过一键回答的方式发送该测试信息对应的反馈信 息, 所述反馈信息即呼叫终端反馈的针对所述测试信息的答案。 一键回答的 方式为用户在呼叫终端上进行一次按键操作来回答呼叫终端所接收的测试信 息。 当用户完成一次按键操作后, 呼叫终端就会返回针对该测试信息的反馈 信息。
步骤 206 ,被叫终端判断呼叫终端的反馈信息是否正确。在本实施例一中, 查询该反馈信息对应的测试信息的答案信息, 并将该反馈信息与答案信息进 行匹配, 若匹配成功, 即判断反馈信息正确, 判断呼叫终端的发送的呼叫请 求是由用户进行呼叫操作; 若匹配不成功, 即判断反馈信息不正确, 判断呼 叫终端发送的呼叫请求是由机器或软件进行呼叫操作。
