Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

本发明实施例提供的技术方案可以应用于VOIP电话识别系统,如图1所示,VOIP电话识别系统包括:至少一个会话发起协议SIP服务器、鉴权设备及中继网关TG,其中,所述鉴权设备位于所述SIP服务器与所述TG之间的通信路径上,鉴权设备包括:前端服务器及至少一个后端服务器。The technical solution provided by the embodiments of the present invention can be applied to a VOIP phone identification system. As shown in FIG. The authentication device is located on the communication path between the SIP server and the TG, and the authentication device includes: a front-end server and at least one back-end server.

本发明实施例提供一种识别VOIP电话的方法,能够识别VOIP电话是否为诈骗电话或为垃圾电话,如图2所示,所述方法包括:Embodiments of the present invention provide a method for identifying a VOIP phone, which can identify whether the VOIP phone is a fraudulent call or a spam call, as shown in Figure 2, the method includes:

201、前端服务器获取呼叫请求信息。201. The front-end server acquires call request information.

其中,呼叫请求信息用于表征主叫用户的呼叫请求信息。Wherein, the call request information is used to represent the call request information of the calling user.

对于本发明实施例,前端服务器位于鉴权设备中,该鉴权设备串行于中继网关的前端,并由前端服务器及至少一个后端服务器组成。在本发明实施例中,由于VOIP语音电话向PSTN域的用户发送呼叫请求消息,该呼叫请求消息必须通过中继网关,因此该呼叫请求消息必须依次经过该鉴权设备及中继网关,至PSTN域的被叫用户侧。For the embodiment of the present invention, the front-end server is located in the authentication device, which is serially connected to the front-end of the relay gateway, and consists of the front-end server and at least one back-end server. In the embodiment of the present invention, since the VOIP voice phone sends a call request message to a user in the PSTN domain, the call request message must pass through the relay gateway, so the call request message must pass through the authentication device and the relay gateway in turn, to the PSTN The called user side of the domain.

其中,该主叫用户可以为VOIP语音电话的主叫用户。Wherein, the calling user may be a calling user of a VOIP voice phone.

对于本发明实施例,前端服务器首先接收到主叫用户发送的会话初始化(英文全称:Session Initiation Protocol,英文缩写:SIP)协议包,然后解析该SIP协议包,得到呼叫请求消息,该呼叫请求消息包含SIP协议的文本信息及该主叫用户的号码信息。For the embodiment of the present invention, the front-end server first receives the session initialization (full name in English: Session Initiation Protocol, English abbreviation: SIP) protocol packet sent by the calling user, then parses the SIP protocol packet to obtain a call request message, and the call request message Contains the text information of the SIP protocol and the number information of the calling user.

202、前端服务器提取呼叫请求信息中的关键信息。202. The front-end server extracts key information in the call request information.

其中,关键信息包括:SIP协议文本信息。Wherein, the key information includes: SIP protocol text information.

203、前端服务器根据SIP协议文本信息,判断主叫用户是否为目标电话用户。203. The front-end server judges whether the calling user is the target phone user according to the SIP protocol text information.

对于本发明实施例,鉴权设备中的前端服务器可以提取该SIP协议的文本信息,进一步地,前端服务器通过判断该呼叫请求的SIP协议的文本信息,以判断该主叫用户是否为目标电话用户。For the embodiment of the present invention, the front-end server in the authentication device can extract the text information of the SIP protocol. Further, the front-end server judges whether the calling user is the target phone user by judging the text information of the SIP protocol of the call request. .

对于本发明实施例,该目标电话用户可以为诈骗电话用户及垃圾电话用户等,其他任何目标电话用户均适用于本发明实施例,在本发明实施例中不做限定。For the embodiment of the present invention, the target phone user may be a fraud phone user or a spam call user, etc. Any other target phone user is applicable to the embodiment of the present invention, and is not limited in the embodiment of the present invention.

本发明实施例提供的识别VOIP电话的方法,前端服务器首先获取呼叫请求信息,然后提取呼叫请求信息中的关键信息,该关键信息中包括:SIP协议文本信息,最后根据SIP协议文本信息,判断主叫用户是否为目标电话用户。与现有技术相比,本发明实施例设置有鉴权设备,前端服务器通过提取呼叫请求信息中的关键信息,能够根据主叫用户呼叫请求信息中的关键信息,判断该主叫用户是否为目标电话用户,该关键信息包含主叫用户的SIP协议文本信息,该目标电话用户可以为诈骗电话用户或为垃圾电话用户,从而可以识别VOIP电话是否为诈骗电话或垃圾电话。In the method for identifying a VOIP phone provided by the embodiment of the present invention, the front-end server first obtains the call request information, and then extracts the key information in the call request information. The key information includes: SIP protocol text information, and finally judges the main Whether the calling user is the target phone user. Compared with the prior art, the embodiment of the present invention is provided with an authentication device, and the front-end server can judge whether the calling user is a target according to the key information in the calling user's call request information by extracting the key information in the call request information. For the phone user, the key information includes the SIP protocol text information of the calling user. The target phone user can be a fraud call user or a spam call user, so that it can be identified whether the VOIP call is a fraud call or a spam call.

在本发明实施例的另一个实现方式中,在如图2所示的实现方式的基础上,步骤202、前端服务器提取呼叫请求信息中的关键信息,可以具体实现为如图3所示的步骤302,由于目标电话用户多数是篡改SIP协议文本信息中的主叫用户显示名字段及主叫用户注册名字段,因此步骤203、前端服务器根据SIP协议文本信息,判断主叫用户是否为目标电话用户,可以具体实现为如图3所示的步骤302-303。In another implementation of the embodiment of the present invention, on the basis of the implementation shown in Figure 2, step 202, the front-end server extracts the key information in the call request information, which can be specifically implemented as the steps shown in Figure 3 302, because most of the target phone users tamper with the calling party's display name field and the calling party's registered name field in the SIP protocol text information, so step 203, the front-end server judges whether the calling party is the target phone user according to the SIP protocol text information , can be specifically implemented as steps 302-303 as shown in FIG. 3 .

301、前端服务器获取呼叫请求信息。301. The front-end server acquires call request information.

其中,呼叫请求信息用于表征主叫用户的呼叫请求信息。Wherein, the call request information is used to represent the call request information of the calling user.

302、前端服务器提取SIP协议文本信息中的主叫用户显示名字段及主叫用户注册名字段。302. The front-end server extracts the field of the display name of the calling user and the field of the registered name of the calling user in the text information of the SIP protocol.

对于本发明实施例,鉴权设备可以通过正则表达式匹配或者通过开源框架OpenSIPS所携带的函数,提取所述主叫用户的显示名字段及主叫用户的注册名字段。For the embodiment of the present invention, the authentication device can extract the display name field of the calling user and the registered name field of the calling user through regular expression matching or functions carried by the open source framework OpenSIPS.

对于本发明实施例,主叫用户的显示名字段可以通过该主叫用户自己设置,该主叫用户显示名字段为在被叫侧显示的用户名,主叫用户的注册名字段用于表示该主叫用户在SIP服务器上注册的用户名。例如,该主叫用户在SIP服务器上注册名为001SIPdomain,并且向被叫侧用户002SIPdomain发送呼叫请求消息,该主叫用户001SIPdomain可以通过改变显示名字段,并将显示名字段设置为003SIPdomain,因此被叫侧用户在接收到该呼叫请求时,显示的用户名为003SIPdomain。For the embodiment of the present invention, the display name field of the calling user can be set by the calling user himself. The display name field of the calling user is the user name displayed on the called side, and the registered name field of the calling user is used to indicate the Username registered on the SIP server by the calling user. For example, the calling user registers as 001SIPdomain on the SIP server and sends a call request message to the called side user 002SIPdomain. The calling user 001SIPdomain can change the display name field and set the display name field to 003SIPdomain, so it is called When the calling side user receives the call request, the displayed user name is 003SIPdomain.

303、前端服务器判断主叫用户显示名字段与主叫用户注册名字段是否相同。303. The front-end server judges whether the display name field of the calling user is the same as the registered name field of the calling user.

对于本发明实施例,前端服务器通过判断该主叫用户的显示名字段与该主叫用户的注册名字段是否相同,以确定该主叫用户是否对显示名字段进行篡改,进而确定该主叫用户是否为目标电话用户。For the embodiment of the present invention, the front-end server determines whether the calling user has tampered with the display name field by judging whether the display name field of the calling user is the same as the registered name field of the calling user, and then determines whether the calling user has tampered with the display name field. Is the target phone user.

可选地,步骤303步骤之后还可以包括:若主叫用户显示名字段与主叫用户注册名字段不相同,则前端服务器确定主叫用户为目标电话用户。Optionally, after step 303, the method may further include: if the field of the display name of the calling user is different from the field of the registered name of the calling user, the front-end server determines that the calling user is the target phone user.

对于本发明实施例,若主叫用户显示名字段与该主叫用户注册名字段不相同,则表征该主叫用户的显示名字段可能被篡改,从而表征该主叫用户可能为目标电话用户,即可能为诈骗电话用户或可能为垃圾电话用户。For the embodiment of the present invention, if the calling user's display name field is different from the calling user's registered name field, the display name field representing the calling user may be tampered with, thereby representing that the calling user may be a target phone user, That is, it may be a scam call user or it may be a spam call user.

在前述实施方式中,在主叫用户显示名字段与主叫用户注册名字段相同的条件下,一般我们认为该主叫用户不属于目标电话用户,可以理解为该主叫用户不属于诈骗电话用户或垃圾电话用户。但是由于主叫用户有能力对SIP协议文本信息中的联系名Contact字段进行修改,使得纵使主叫用户显示名字段与主叫用户注册名字段相同的条件下,依然可以通过修改联系名Contact字段来更改被叫用户来电显示的主叫用户名,而这一类电话实质上应该归结为诈骗电话或垃圾电话。In the aforementioned embodiments, under the condition that the calling party’s display name field is the same as the calling party’s registered name field, we generally believe that the calling party does not belong to the target phone user, and it can be understood that the calling user does not belong to a fraudulent phone user. or spam callers. But because the calling user has the ability to modify the contact name Contact field in the SIP protocol text information, even if the calling user's display name field is under the same condition as the calling user's registered name field, it can still be modified by modifying the contact name Contact field. Change the calling user name of the called user's caller ID, and this type of call should essentially be attributed to a scam call or a spam call.

为识别出这一类用户,本发明实施例中的另一种可能的实现方式,可执行于步骤303之后,在该实现方式中,如图4所示包括步骤304-305。In order to identify this type of users, another possible implementation in the embodiment of the present invention may be performed after step 303. In this implementation, steps 304-305 are included as shown in FIG. 4 .

304、若主叫用户显示名字段与主叫用户注册名字段相同,则前端服务器提取SIP协议文本信息中的联系名Contact字段。304. If the calling user display name field is the same as the calling user registered name field, the front-end server extracts the contact name Contact field in the SIP protocol text information.

对于本发明实施例,联系人(英文全称:Contact)字段在SIP标准协议中用于表征主叫用户告知被叫用户的其对应的联系方式,即当该被叫用户向该主叫用户发送呼叫请求消息时,所需要发送的统一资源标识符(英文全称:UniformResource Identifier,英文缩写:URI)地址。For the embodiment of the present invention, the contact person (full name in English: Contact) field is used in the SIP standard protocol to indicate that the calling user informs the called user of its corresponding contact information, that is, when the called user sends a call to the calling user When requesting a message, the uniform resource identifier (English full name: UniformResource Identifier, English abbreviation: URI) address that needs to be sent.

对于本发明实施例,前端服务器可以通过正则表达式或者通过开源框架是OpenSIPs所携带的函数,获取该主叫用户的Contact字段。For the embodiment of the present invention, the front-end server can obtain the Contact field of the calling user through a regular expression or through a function carried by the open source framework OpenSIPs.

305、前端服务器判断主叫用户显示名字段及主叫用户注册名字段所示的内容与Contact字段所示的内容是否相同。305. The front-end server judges whether the content shown in the field of the display name of the calling user and the field of the registered name of the calling user is the same as that shown in the field of Contact.

对于本发明实施例,前端服务器通过判断主叫用户显示名字段、主叫用户注册名字段及Contact字段三者之间是否相同,能够判断该主叫用户的SIP协议的字段是否被篡改,从而可以判断该主叫用户是否为目标电话用户,即诈骗电话用户,进而可以进一步地提高识别VOIP诈骗电话的准确度。For the embodiment of the present invention, the front-end server can judge whether the field of the SIP protocol of the calling user has been tampered with by judging whether the calling user's display name field, the calling user's registered name field and the Contact field are the same. Judging whether the calling user is a target phone user, that is, a fraudulent phone user, can further improve the accuracy of identifying VOIP fraudulent calls.

本发明实施例中的另一种可能的实现方式,在步骤305之后,还可以包括:若主叫用户显示名字段及主叫用户注册名字段所示的内容及Contact字段所示的内容不相同,则前端服务器确定主叫用户为目标电话用户。Another possible implementation in the embodiment of the present invention, after step 305, may also include: if the content shown in the field of the display name of the calling party and the field of the registered name of the calling party is different from the content shown in the field of the Contact , the front-end server determines that the calling user is the target phone user.

对于本发明实施例,若主叫用户显示名字段及主叫用户注册名字段所示的内容与Contact字段所示的内容不相同,即表示该主叫用户的SIP协议文本信息被篡改,则该主叫用户可能为目标电话用户,即诈骗电话用户。For the embodiment of the present invention, if the content shown in the calling user's display name field and the calling user's registered name field is different from the content shown in the Contact field, it means that the SIP protocol text information of the calling user has been tampered with, then the The calling user may be the target phone user, that is, a fraud phone user.

在前述实施方式中,在主叫用户显示名字段及主叫用户注册名字段所示的内容与Contact字段所示的内容相同的条件下,一般我们认为该主叫用户不属于目标电话用户,可以理解为该主叫用户不属于诈骗电话用户或垃圾电话用户。但是由于主叫用户有能力对呼叫请求消息中的号码信息进行修改,使得纵使主叫用户显示名字段及主叫用户注册名字段所示内容与Contact字段所示的内容相同的条件下,依然可以伪装为一些特殊用户的号码信息,而这一类电话实质上应该归结为诈骗电话用户或垃圾电话用户。In the aforementioned embodiments, under the condition that the content shown in the calling party's display name field and the calling party's registered name field is the same as the content shown in the Contact field, we generally believe that the calling party does not belong to the target phone user, and can It is understood that the calling user is not a scam call user or a spam call user. But because the calling party has the ability to modify the number information in the call request message, even if the content shown in the field of the display name of the calling party and the field of the registered name of the calling party is the same as that shown in the field of the Contact field, it is still possible It is disguised as the number information of some special users, and this type of calls should be attributed to scam call users or spam call users in essence.

为识别出这一类用户,在本发明实施例中的另一种可能的实现方式中,可执行于步骤305之后,在该实现方式中,如图5所示包括步骤306-309。To identify this type of user, in another possible implementation manner in the embodiment of the present invention, it may be performed after step 305, and in this implementation manner, steps 306-309 are included as shown in FIG. 5 .

306、若主叫用户显示名字段及主叫用户注册名字段所示的内容与Contact字段所示的内容相同,则前端服务器提取呼叫请求信息中的主叫用户的号码信息。306. If the content shown in the calling party's display name field and the calling user's registered name field is the same as that shown in the Contact field, the front-end server extracts the calling party's number information in the call request information.

对于本发明实施例,主叫用户的号码信息为该用户对应的号码。例如,主叫用户1的号码信息可以为110、01060123456或者为18601101234。For the embodiment of the present invention, the number information of the calling user is the number corresponding to the user. For example, the number information of calling user 1 may be 110, 01060123456 or 18601101234.

对于本发明实施例,若主叫用户显示名字段、主叫用户注册名字段及Contact字段三者之间相同,则表征该主叫用户的SIP文本信息可能没有被篡改。在本发明实施例中,前端服务器提取该主叫用户的号码信息,以判断主叫用户是否为伪装的PSTN域的电话用户。For the embodiment of the present invention, if the display name field of the calling user, the registered name field of the calling user and the Contact field are the same, the SIP text information representing the calling user may not have been tampered with. In the embodiment of the present invention, the front-end server extracts the number information of the calling user to determine whether the calling user is a phone user in a fake PSTN domain.

307、前端服务器确定主叫用户的号码信息对应的号码类型。307. The front-end server determines the number type corresponding to the number information of the calling user.

其中,号码类型包括:短号码、固定号码及手机号码。Among them, the number type includes: short number, fixed number and mobile phone number.

对于本发明实施例,前端服务器通过判断该主叫用户号码的长度或者该号码信息对应的其他特征,以判断该主叫用户号码的号码类型。For the embodiment of the present invention, the front-end server judges the number type of the calling party number by judging the length of the calling party number or other features corresponding to the number information.

例如,若主叫用户1的号码为110,则该主叫用户1的号码类型为短号码;若该主叫用户2的号码为01060123456,则该主叫用户2号码的号码类型为固定号码;若该主叫用户号码为18601101234,则该主叫用户3的号码类型为手机号码。For example, if the number of the calling user 1 is 110, then the number type of the calling user 1 is a short number; if the number of the calling user 2 is 01060123456, then the number type of the calling user 2 number is a fixed number; If the calling user number is 18601101234, then the number type of the calling user 3 is a mobile phone number.

对于本发明实施例,前端服务器通过确定该主叫用户对应的号码类型,能够将该主叫用户对应的号码信息发送至该号码类型对应的后端服务器进行检索,而不需要在所有的后端服务器中进行检索,从而可以提高检索号码信息的速度,进而可以提高识别VOIP诈骗电话的速度。For the embodiment of the present invention, by determining the number type corresponding to the calling user, the front-end server can send the number information corresponding to the calling user to the back-end server corresponding to the number type for retrieval, without requiring all back-end Searching in the server can improve the speed of retrieving number information, and then can improve the speed of identifying VOIP fraudulent calls.

308、前端服务器将主叫用户的号码信息发送至号码类型对应的后端服务器。308. The front-end server sends the number information of the calling user to the back-end server corresponding to the number type.

对于本发明实施例,鉴权设备中包含至少一个后端服务器,该后端服务器用于存储指定电话的号码信息,具体地,该后端服务器存储着诈骗用户的号码或者垃圾用户的号码信息。其中,后端服务器可以根据主叫用户的号码信息对应的号码类型进行分类。具体地,后端服务器可以分为存储短号码的后端服务器、存储固定电话号码的后端服务器及存储手机号码的后端服务器。For the embodiment of the present invention, the authentication device includes at least one back-end server, and the back-end server is used to store the number information of the specified phone, specifically, the back-end server stores the number information of fraudulent users or spam users. Wherein, the backend server can classify according to the number type corresponding to the number information of the calling user. Specifically, the back-end server can be divided into a back-end server storing short numbers, a back-end server storing fixed phone numbers, and a back-end server storing mobile phone numbers.

对于本发明实施例,由于主叫用户的号码的位长不同、数据量不同,则存储不同类型的号码所需的后端服务器亦不相同。在本发明实施例中,鉴权设备可以按照一定的比例为不同的类型的号码配置后端服务器。For the embodiment of the present invention, since the numbers of calling users have different bit lengths and different data volumes, the back-end servers required to store different types of numbers are also different. In the embodiment of the present invention, the authentication device can configure back-end servers for different types of numbers according to a certain ratio.

例如,鉴权设备可以将短号码、固定号码及手机号码的后端服务器数量按照1:2:4进行配置。其中,后端服务器1用于存储目标用户的短号码、后端服务器2及后端服务器3用于存储固定号码、后端服务器4、后端服务器5、后端服务器6及后端服务器7用用户存储手机号码,如图7所示。For example, the authentication device can configure the number of back-end servers for short numbers, fixed numbers and mobile numbers according to 1:2:4. Among them, the back-end server 1 is used to store the short number of the target user, the back-end server 2 and the back-end server 3 are used to store the fixed number, the back-end server 4, the back-end server 5, the back-end server 6 and the back-end server 7 are used The user stores the mobile phone number, as shown in Figure 7.

对于本发明实施例,前端服务器通过判断该主叫用户的号码信息对应的号码类型,将该主叫用户的号码信息发送至该号码类型对应的后端服务器。例如,该主叫用户的号码对应的号码类型为短号码,则前端服务器将该号码发送至短号码对应的后端服务器,即后端服务器1。For the embodiment of the present invention, the front-end server sends the number information of the calling user to the back-end server corresponding to the number type by judging the number type corresponding to the number information of the calling user. For example, if the number type corresponding to the number of the calling user is a short number, the front-end server sends the number to the back-end server corresponding to the short number, that is, the back-end server 1 .

309、后端服务器根据主叫用户的号码信息对应的内存索引,判断后端服务器中是否存在主叫用户的号码信息。309. The backend server judges whether the number information of the calling user exists in the backend server according to the memory index corresponding to the number information of the calling user.

对于本发明实施例,内存索引为按位进行索引。其中一个字符byte存在8个字节bit,能够存储整形数字0-7,即在字节所在位上设置为1,例如,若在后端服务器的内存中存储数字5、6,则该后端服务器的内存中的形式为[00000110],即在第6位及第7位改为1。For this embodiment of the present invention, the memory index is a bitwise index. One of the character bytes has 8 byte bits, which can store integer numbers 0-7, that is, set the byte position to 1. For example, if the numbers 5 and 6 are stored in the memory of the backend server, the backend The format in the server's memory is [00000110], that is, the sixth and seventh digits are changed to 1.

对于本发明实施例,对于存储手机号码的存储器由于手机号码较长,因此利用内存索引的方法,仍存在数据量较大、占用较多内存的情况,并且造成存储空间的浪费。例如,手机号码的一个号段存在有1亿个的数据,并且手机号码均以1开头,若直接采用上述内存索引的方式,则需要1012bit的空间,并且由于手机号码的第一位为1,因此0-10000000000的空间地址没有利用,从而导致大量的存储空间的浪费。For the embodiment of the present invention, since the mobile phone number is long in the memory for storing the mobile phone number, the method of using the memory index still has a large amount of data, takes up a lot of memory, and causes a waste of storage space. For example, there are 100 million pieces of data in a segment of a mobile phone number, and the mobile phone number starts with 1. If the above-mentioned memory index method is used directly, a space of 1012 bits is required, and since the first digit of the mobile phone number is 1, so the space address of 0-10000000000 is not utilized, resulting in a large waste of storage space.

对于本发明实施例,鉴于上述情况,对于手机号码,后端服务器可以将手机号码首先转换为哈希编码,即将11位的手机号码映射为8位的随机数,并且各个11位的号码与各个8为随机数之间为一一对应的关系。在本发明实施例中,鉴权设备通过将手机号码首先转换为哈希编码,例如,18612345678转换为哈希编码为23456789;18612345679转换为哈希编码为12345678;18612345676转换为哈希编码为33456234,如图8所示,然后在利用内存索引的方式存储该手机号码,能够将手机号码所占用的内存空间减少1000倍,从而可以减少手机号码所需要占用的内存空间,并避免了内存空间的浪费。For the embodiment of the present invention, in view of the above situation, for the mobile phone number, the backend server can first convert the mobile phone number into a hash code, that is, to map the 11-digit mobile phone number to an 8-digit random number, and each 11-digit number and each 8 is a one-to-one correspondence between random numbers. In the embodiment of the present invention, the authentication device first converts the mobile phone number into a hash code, for example, 18612345678 is converted into a hash code into 23456789; 18612345679 is converted into a hash code into 12345678; As shown in Figure 8, storing the mobile phone number in the way of memory index can reduce the memory space occupied by the mobile phone number by 1000 times, thereby reducing the memory space occupied by the mobile phone number and avoiding the waste of memory space .

对于本发明实施例,若后端服务器接收到的主叫用户的号码为手机号码,则将该手机号码转化为哈希编码,再按照该哈希编码对应的内存索引检索该后端服务器中是否存在该号码。For the embodiment of the present invention, if the number of the calling user received by the back-end server is a mobile phone number, then the mobile phone number is converted into a hash code, and then the memory index corresponding to the hash code is used to search whether the number in the back-end server is The number exists.

在前述实施方式中,在后端服务器中未检索出主叫用户的号码信息的条件下,一般我们认为该主叫用户不属于目标电话用户,可以理解为该主叫用户不属于诈骗电话用户或垃圾电话用户。但是由于主叫用户有能力伪装为PSTN域中的其他号码信息,使得纵使在后端服务器中未存在该主叫用户的号码信息的条件下,依然可以通过伪装为PSTN域中的其他号码信息,而这一类电话用户实质上应该归结为诈骗电话用户或垃圾电话用户。In the foregoing embodiments, under the condition that the calling user’s number information is not retrieved from the back-end server, we generally believe that the calling user does not belong to the target phone user. It can be understood that the calling user does not belong to a fraudulent phone user or Spam callers. However, since the calling user has the ability to pretend to be other number information in the PSTN domain, even if the number information of the calling user does not exist in the back-end server, it can still be disguised as other number information in the PSTN domain. And this type of phone users should be attributed to fraud phone users or spam phone users in essence.

为识别出这一类用户,在本发明实施例中的另一种可能的实现方式中,可执行于步骤309之后,在该实现方式中,如图6所示包括步骤310-311。In order to identify this type of user, in another possible implementation manner in the embodiment of the present invention, it may be performed after step 309, and in this implementation manner, steps 310-311 are included as shown in FIG. 6 .

310、若后端服务器不存在主叫用户的号码信息,则前端服务器根据主叫用户的号码信息,并通过公共交换电话网络PSTN域呼叫主叫用户。310. If the back-end server does not have the number information of the calling user, the front-end server calls the calling user through the PSTN domain of the public switched telephone network according to the number information of the calling user.

对于本发明实施例,由于后端服务器中存储的目标号码信息不全,因此可能无法识别所有的目标号码、即伪装号码,因此若鉴权设备的后端服务器中不存在该主叫用户的号码信息,则需要前端服务器反向呼叫该主叫用户的号码信息,进一步地,判断该主叫用户是否为目标电话用户。For the embodiment of the present invention, since the target number information stored in the back-end server is incomplete, it may not be possible to identify all target numbers, that is, fake numbers. Therefore, if the number information of the calling user does not exist in the back-end server of the authentication device , then the front-end server needs to reverse call the number information of the calling user, and further, determine whether the calling user is the target phone user.

311、若前端服务器接收到PSTN域发送的确定响应消息,则前端服务器确定所述主叫用户为目标电话用户。311. If the front-end server receives the confirmation response message sent by the PSTN domain, the front-end server determines that the calling user is the target phone user.

对于本发明实施例,若前端服务器通过PSTN域反向呼叫该主叫用户的号码信息,并且该前端服务器接收到PSTN域发送的确定响应消息,即PSTN域中存在该主叫用户的号码信息,由于该主叫用户的号码信息为VOIP电话的号码信息,因此该主叫用户的号码信息可能是伪装PSTN域的号码,即该主叫用户可能为目标电话用户。For this embodiment of the present invention, if the front-end server reverse calls the number information of the calling user through the PSTN domain, and the front-end server receives a confirmation response message sent by the PSTN domain, that is, the number information of the calling user exists in the PSTN domain, Since the number information of the calling user is the number information of the VOIP phone, the number information of the calling user may be a number pretending to be a PSTN domain, that is, the calling user may be a target phone user.

对于本发明实施例,步骤311之后,还可以包括:首先前端服务器确定主叫用户的号码信息对应的号码类型,然后前端服务器将主叫用户的号码信息,发送至号码类型对应的后端服务器,最后后端服务器将主叫用户的号码信息存储至后端服务器的磁盘中,并在后端服务器的内存中生成内存索引。For the embodiment of the present invention, after step 311, it may also include: first, the front-end server determines the number type corresponding to the number information of the calling user, and then the front-end server sends the number information of the calling user to the back-end server corresponding to the number type, Finally, the backend server stores the number information of the calling user in the disk of the backend server, and generates a memory index in the memory of the backend server.

对于本发明实施例,前端服务器通过反向呼叫确定的目标电话用户对应的号码信息添加至该号码类型对应的后端服务器中,若再次出现相同的目标电话时,能够仅通过在后端服务器的内存中进行检索,判断出该后端服务器中是否存在该号码信息,即能够判断该主叫用户是否为目标电话用户,而不需要通过反向呼叫,即可以确定目标电话用户,从而可以进一步地降低识别VOIP诈骗电话的复杂度。For the embodiment of the present invention, the number information corresponding to the target phone user determined by the front-end server through the reverse call is added to the back-end server corresponding to the number type. Retrieve in the internal memory to determine whether the number information exists in the back-end server, that is, it can determine whether the calling user is the target phone user, and the target phone user can be determined without reverse calling, so that further Reduce the complexity of identifying VOIP scam calls.

对于本发明实施例,若前端服务器未接收到PSTN域发送的确定响应消息,则确定该PSTN域中未存在该主叫用户的号码信息,即该主叫用户未伪装PSTN域的用户,从而可以判断该主叫用户可能为非目标用户,即该主叫用户为非诈骗用户。在本发明实施例中,若该主叫用户不是目标电话用户,则前端服务器将该主叫用户对应的呼叫请求信息发送至中继网关,进而可以通过PSTN域呼叫该域中的存在的用户。For the embodiment of the present invention, if the front-end server does not receive the confirmation response message sent by the PSTN domain, then it is determined that the number information of the calling user does not exist in the PSTN domain, that is, the calling user does not pretend to be a user of the PSTN domain, so that It is determined that the calling user may be a non-target user, that is, the calling user is not a fraudulent user. In the embodiment of the present invention, if the calling user is not the target phone user, the front-end server sends the call request information corresponding to the calling user to the trunk gateway, and then calls the existing users in the domain through the PSTN domain.

对于本发明实施例,在前述实施例中,各个实施例可以单独执行,也可以混合执行,以实现判断该主叫用户是否为目标电话用户,即是否为诈骗电话用户或者为垃圾电话用户,然而当上述实施例混合执行时,各个实施例要在上述相应的限定条件下执行。For the embodiments of the present invention, in the aforementioned embodiments, each embodiment can be executed independently or in combination, so as to realize judging whether the calling user is a target phone user, that is, whether it is a scam call user or a spam call user, however When the above-mentioned embodiments are implemented in combination, each embodiment should be implemented under the above-mentioned corresponding limited conditions.

进一步地,本发明实施例提供的识别VOIP电话的方法,前端服务器通过判断主叫用户显示名字段、主叫用户注册名字段及Contact字段三者之间是否相同,能够判断该主叫用户的SIP协议的字段是否被篡改,从而可以判断该主叫用户是否为目标电话用户,即诈骗电话用户,进而可以进一步地提高识别VOIP诈骗电话的准确度;前端服务器通过确定该主叫用户对应的号码类型,能够将该主叫用户对应的号码信息发送至该号码类型对应的后端服务器进行检索,而不需要在所有的后端服务器中进行检索,从而可以提高检索号码信息的速度,进而可以提高识别VOIP诈骗电话的速度;前端服务器通过反向呼叫确定的目标电话用户对应的号码信息添加至该号码类型对应的后端服务器中,若再次出现相同的目标电话时,能够仅通过在后端服务器的内存中进行检索,判断出该后端服务器中是否存在该号码信息,即能够判断该主叫用户是否为目标电话用户,而不需要通过反向呼叫,即可以确定目标电话用户,从而可以进一步地降低识别VOIP诈骗电话的复杂度。Further, in the method for identifying a VOIP phone provided by the embodiment of the present invention, the front-end server can determine the SIP address of the calling user by judging whether the display name field of the calling user, the registered name field of the calling user and the Contact field are the same. Whether the field of the agreement has been tampered with, so that it can be judged whether the calling user is the target phone user, that is, a fraudulent phone user, and the accuracy of identifying VOIP fraudulent calls can be further improved; the front-end server determines the number type corresponding to the calling user , the number information corresponding to the calling user can be sent to the back-end server corresponding to the number type for retrieval, without the need to search in all the back-end servers, so that the speed of retrieval of number information can be improved, and the recognition can be improved. The speed of VOIP fraudulent calls; the number information corresponding to the target phone user determined by the front-end server through the reverse call is added to the back-end server corresponding to the number type. Retrieve in the internal memory to determine whether the number information exists in the back-end server, that is, it can determine whether the calling user is the target phone user, and the target phone user can be determined without reverse calling, so that further Reduce the complexity of identifying VOIP scam calls.
