The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
Before introducing the voice call method provided in the embodiments of the present application, some concepts involved in the embodiments of the present application are first described:
session initiation protocol (Session Initiation Protocol, SIP), also known as session initiation protocol, is a multimedia communication protocol established by the internet engineering task force (Internet Engineering Task Force, IETF), which is a text-based application-layer control protocol proposed as a standard for creating, modifying and terminating interactive user sessions involving a variety of multimedia elements, including video, voice, instant messaging, online gaming and virtual reality.
Voice over IP (VoIP), which is a Voice call technology, is to implement Voice call and multimedia conference via IP protocol, that is, to communicate via internet; other informal names are IP phones, internet phones, broadband phone services, etc.
Please refer to fig. 1, which illustrates a schematic structural diagram of a voice call system provided in an embodiment of the present application; the voice call system includes: the system comprises terminal equipment, a security verification voice gateway and a security operation and maintenance platform; the security check voice gateway is respectively communicated with the terminal equipment and the security operation and maintenance platform; specific examples are: the first security check voice gateway is respectively communicated with the first terminal equipment and the security operation and maintenance platform, and the second security check voice gateway is respectively communicated with the second terminal equipment and the security operation and maintenance platform.
The above voice call system may further include: the Session Initiation Protocol (SIP) server is respectively communicated with the security check voice gateway and the security operation and maintenance platform; specific examples are: the first SIP server is respectively communicated with the first security check voice gateway and the security operation and maintenance platform, the second SIP server is respectively communicated with the security check voice gateway and the second security operation and maintenance platform, and the first SIP server and the second SIP server can be communicated with each other through a wide area network (such as the Internet).
And the terminal equipment generates a VoIP voice call request according to the equipment information, the calling number and the called number, and sends the voice call request to the security check voice gateway. The terminal device refers to a sending device of a voice call request, for example: personal computer, video telephone and voice fixed telephone with voice call function, the voice call request sent by the terminal equipment is passed through the safety check voice gateway.
And the security check voice gateway receives a voice call request sent by the terminal equipment, generates a check authentication request according to equipment information, a calling number and a called number in the voice call request when the voice call request is determined not to belong to the local call, and then sends the check authentication request to the security operation and maintenance platform. Conversely, when it is determined that the voice call request belongs to the local call, the voice call request may be directly released without checking authentication with the secure operation and maintenance platform.
It should be noted that, the above-mentioned security check voice gateway refers to a voice gateway with a security check function added thereto, where the security check function may be embodied as a software program deployed and running in the voice gateway (the security check voice gateway at this time may be a server that performs both the voice gateway function and the security check function), or may be embodied as a hardware device that performs the security check function (the security check voice gateway at this time may be an integral device of two devices that communicate with each other, including a voice gateway and a server that performs the security check function, where the voice gateway and the server may communicate with each other).
The security operation and maintenance platform receives a verification and authentication request sent by the security verification voice gateway, performs security verification and authentication on equipment information, a calling number and a called number in the verification and authentication request by using a preset call policy, obtains a verification and authentication result, and then sends the verification and authentication result to the security verification voice gateway.
The security check voice gateway receives the check authentication result sent by the security operation and maintenance platform, processes the voice call request according to the check authentication result, and the specific process of processing the voice call request can include: the security check voice gateway judges whether the check authentication result is passed or not; if yes, sending a voice call request to the SIP server, otherwise, sending a call blocking response to the terminal equipment. The SIP server receives the voice call request sent by the security check voice gateway, generates a path monitoring request according to call path information of the voice call request when the voice call request is determined not to belong to the call in the network, and then sends the path monitoring request to the security operation and maintenance platform. The safety operation and maintenance platform receives the path monitoring request sent by the SIP server, monitors call path information in the path monitoring request, obtains a path monitoring result, and then sends the path monitoring result to the SIP server. The SIP server receives the path monitoring result sent by the security operation and maintenance platform and judges whether the path monitoring result passes or not; if yes, the voice call request is released, otherwise, the call blocking response is sent to the terminal equipment through the security check voice gateway.
The voice call method provided in the embodiment of the present application may be executed by an electronic device, where the electronic device refers to a server or a network device that executes a computer program function, and the server refers to a device that provides a computing service through a network, and the server is for example: an x86 server and a non-x 86 server, the non-x 86 server comprising: mainframe, mini-computer and UNIX server; the network device includes: three layers of switches and routers, etc.
Application scenarios to which the voice call method is applicable are described below, where the application scenarios include, but are not limited to: the voice call method is used for avoiding the telephone fee loss of the voice service of the voice operator, thereby improving the safety of the voice service for the voice operator, or enhancing the functions of the safety voice service server and the safety check voice gateway, thereby customizing and developing the safety voice service server, the safety check voice gateway or providing the safety voice operation and maintenance solution service for the voice operator, and the like.
Please refer to fig. 2, which illustrates a flowchart of a voice call method executed by the secure operation platform according to an embodiment of the present application; the voice communication method can be applied to a safe operation and maintenance platform (namely, the safe operation and maintenance platform can be executed), and the safe operation and maintenance platform and the safe verification voice gateway are communicated with each other; the main idea of the voice call method is that the equipment information of the terminal equipment, the calling number and the called number sent by the terminal equipment are subjected to safety verification to obtain a verification result, and the voice call request is processed according to the verification result, so that a safety access mechanism is set for voice service of a telecom operator, the risk that a network attacker steals a voice service network to dial an international long distance call is avoided, and the safety of transmitting voice data on the Internet is effectively improved. The voice call method executed by the secure operation platform may include:
Step S110: the security operation and maintenance platform receives a verification authentication request sent by the security verification voice gateway, wherein the verification authentication request is sent when the security verification voice gateway determines that the received voice call request does not belong to a local call.
The embodiment of step S110 described above is, for example: the security check voice gateway receives a VoIP voice call request sent by the terminal equipment, judges whether the voice call request belongs to a local call, and can directly pass if the voice call request belongs to the local call; if the voice call request does not belong to the local call, generating a verification authentication request according to the equipment information, the calling number and the called number in the voice call request, and then sending the verification authentication request to the security operation and maintenance platform.
After step S110, step S120 is performed: and the safety operation and maintenance platform uses a preset call strategy to carry out safety verification and authentication on the equipment information, the calling number and the called number in the verification and authentication request, and a verification and authentication result is obtained.
The preset call policy refers to a preset call policy, and the authentication process using the preset call policy includes: acquiring a preset strategy corresponding to the service scene from a strategy center library, and authenticating the equipment information by using the preset strategy corresponding to the service scene to obtain a verification authentication result.
The security verification authentication method in step S120 includes, but is not limited to:
the first security verification authentication method performs security verification authentication on equipment information, where the equipment information includes subscriber identity module (Subscriber Identity Module, SIM) card information and a call location of the SIM card. The authentication of the SIM card specifically includes: in the incoming call scene of the security call service, a security call strategy corresponding to the incoming call scene is obtained from a strategy center library, and the security call strategy is used for checking and authenticating the equipment information, so that the use record of the SIM card can be queried according to the SIM card information, and whether the SIM card is illegal or in a blacklist is judged according to the use record of the SIM card, and if the SIM card is illegal or in the blacklist, the checking and authenticating result is set as not passing; and if the SIM card is in the white list, setting the verification authentication result to pass. Also for example: the equipment information comprises the call position of the SIM card, and if the call position of the SIM card is the geographic position in the process of frequent call, the authentication is passed; if the call position of the SIM card is not the geographical position in the process of frequent call, further authenticating whether the SIM card is stolen, and the like, if the SIM card is not stolen, setting the verification authentication result to pass, otherwise, setting the verification authentication result to not pass.
The second security check authentication method performs security check authentication on the calling number and the called number, and judges whether the calling number and the called number pass the security check according to preset rules, where the preset rules include: whether the number of call minutes of the calling number or the called number exceeds the number of allowed local call minutes of the host number or the called number in the month (for example, only 100 minutes can be called in the month, an alarm message is sent after exceeding a preset proportion, etc.), or whether the calling number and the called number are in a managed list (white list or black list, etc.), or whether a history call record and a history message record are queried according to the calling number or the called number, then whether abnormal (stolen) conditions are generated in the call and the message of the calling number and the called number are judged according to the history call record and the history message record, or whether the calling number is in the black list of the called number is judged, etc.
The third security verification authentication mode is combined with the first security verification authentication mode and the second security verification authentication mode to carry out security verification authentication on the equipment information, the calling number and the called number; the specific embodiment is similar to the first security check authentication method and the second security check authentication method described above, and therefore, will not be described herein.
After step S120, step S130 is performed: and the security operation and maintenance platform sends a verification authentication result to the security verification voice gateway.
The embodiment of step S130 described above is, for example: the security operation and maintenance platform sends a verification authentication result to the security verification voice gateway; the security check voice gateway receives a check authentication result sent by the security operation and maintenance platform and judges whether the check authentication result passes or not; if the verification authentication result is passed, the security verification voice gateway sends a voice call request to the SIP server; if the verification authentication result is not passed, the security verification voice gateway sends a call blocking response to the terminal equipment.
After step S130, step S140 is performed: the security operation and maintenance platform receives a path monitoring request sent by the SIP server, wherein the path monitoring request is sent by the SIP server when the received voice call request is determined not to belong to the network for call.
The embodiment of step S140 described above is, for example: the SIP server receives the voice call request sent by the security check voice gateway, and if the voice call request is determined to belong to the call in the network, the voice call request is directly released. And the SIP server searches call path information corresponding to the voice call request in a database or a file system only when the voice call request is determined not to belong to the call in the network, generates a path monitoring request according to the call path information of the voice call request, and sends the path monitoring request to the security operation and maintenance platform. The secure operation platform receives the path monitoring request sent by the SIP server through a transmission control protocol (Transmission Control Protocol, TCP) or a user datagram protocol (User Datagram Protocol, UDP).
After step S140, step S150 is performed: and the safety operation and maintenance platform monitors call path information in the path monitoring request to obtain a path monitoring result.
The call path information may include: a start ingress device identity, an ingress operator identity and a next hop device identity; the initial ingress device identifier may be understood as a device identifier of a call initial ingress, the ingress operator identifier may be understood as an operator identifier of the initial ingress on the call path, and the next hop device identifier may be understood as a device identifier of a next hop of the call path.
The embodiment of the above step S150 is divided into two scenarios (here, taking the case that the first terminal device sends a voice call request to the second terminal device as an example, the voice call request may sequentially pass through the first security check voice gateway, the first SIP server, the second SIP server, and the second security check voice gateway):
the first type of incoming call scenario, that is, the SIP server is a first SIP server that performs ingress security detection, and call path information reported by the first SIP server is a call path at an ingress, where the incoming call scenario may include:
if the initial entry device identifier is the identifier of the first security check voice gateway, the entry operator identifier is a preset operator identifier, and the next-hop device identifier is the voice internal network local exit identifier corresponding to the preset operator identifier, a path monitoring result indicating that the path is monitored is sent to the first SIP server.
If the initial entrance equipment identifier is the identifier of the first security check voice gateway, the entrance operator identifier is a preset operator identifier, and the next-hop equipment identifier is the voice internal network local exit identifier of the second SIP server, a path monitoring result indicating that the path is monitored is sent to the first SIP server.
If the initial entry device identifier is the identifier of the first security check voice gateway, the entry operator identifier is the preset operator identifier, and the next hop device identifier is the identifier of the first security check voice gateway or the identifier of the second security check voice gateway, a path monitoring result indicating that the path monitoring is not passed is sent to the first SIP server or the second SIP server.
The second type of outgoing call scenario, that is, the SIP server is a second SIP server that performs egress security detection, and call path information reported by the second SIP server is a call path at an egress, where the incoming call scenario may include: judging whether the initial inlet equipment identifier is the identifier of a first security check voice gateway or not; if not, sending a path monitoring result of the path monitoring to a second SIP server; if the initial entry device identifier is the identifier of the first security check voice gateway and the calling number is the intra-office number, sending a path monitoring result through path monitoring to a second SIP server; if the initial ingress device identifier is the identifier of the first security check voice gateway and the calling number is not the intra-office number, sending a path monitoring result indicating that the path monitoring is not passed to the second SIP server.
Because the first SIP server and the second SIP server both report the call path information to the security operation and maintenance platform, the security operation and maintenance platform can easily verify whether the call path information reported by the following SIP server is correct (for example, whether the next hop address is the address of the following SIP server) according to the call path information reported by the SIP server before.
Optionally, in the process of executing the voice call method by the secure operation platform, statistics may be performed on the calling number and/or the called number, call map information such as a history call record of the calling number and/or the called number is obtained, and a call path topology capable of backtracking is generated according to the history call record. After the call path topology is generated, call map information such as a history call record and the call path topology may also be output on a large screen (e.g., a call area map or the like) in real time. An administrator can observe the current full-network call list in the current voice call system in real time, can control the occurrence times of forbidden words in the monitored call through the current full-network call list, and can determine whether to block the voice call according to the occurrence times of the forbidden words, so that the technical effects of being visible, safe and controllable in call are achieved.
After step S150, step S160 is performed: and the safe operation and maintenance platform sends the path monitoring result to the SIP server.
The embodiment of step S160 described above is, for example: the security operation and maintenance platform sends a path monitoring result to the SIP server through a TCP protocol or a UDP protocol, and judges whether the path monitoring result passes or not; if the path monitoring result is passed, releasing the voice call request; if the path monitoring result is not passed, a call blocking response is returned to the terminal equipment corresponding to the voice call request.
Please refer to fig. 3, which is a flowchart illustrating a voice call method executed by the security check voice gateway according to an embodiment of the present application; the voice communication method can be applied to a safety check voice gateway which is respectively communicated with the terminal equipment, the Session Initiation Protocol (SIP) server and the safety operation and maintenance platform; the voice call method executed by the security check voice gateway may include:
step S210: the security check voice gateway receives a voice call request sent by the terminal equipment.
The embodiment of step S210 described above is, for example: the first terminal equipment sends a voice call request to the security check voice gateway through a TCP protocol or a UDP protocol, and the voice call request is used for establishing a call with the second terminal equipment; the security check voice gateway receives the VoIP voice call request sent by the terminal equipment through the TCP protocol or the UDP protocol.
After step S210, step S220 is performed: and when the security check voice gateway determines that the voice call request does not belong to the local call, generating a check authentication request according to the equipment information, the calling number and the called number in the voice call request.
Of course, if the security check voice gateway determines that the voice call request belongs to the local call, the voice call request can be directly released, and check authentication on the voice call request is not required.
After step S220, step S230 is performed: the security check voice gateway sends a check authentication request to the security operation and maintenance platform, so that the security operation and maintenance platform uses a preset call strategy to carry out security check authentication on equipment information, a calling number and a called number in the check authentication request, and a check authentication result is obtained and returned.
The implementation principle and implementation of this step S230 are similar to those of the steps S110 to S120, and thus, the implementation principle and implementation thereof will not be described here, and reference may be made to the descriptions of the steps S110 to S120 if it is unclear.
After step S230, step S240 is performed: and the security check voice gateway receives a check authentication result sent by the security operation and maintenance platform and processes the voice call request according to the check authentication result.
The embodiment of step S240 described above is, for example: the security verification voice gateway uses a programming language to determine whether the verification authentication result is passed, and a programming language such as: C. c++, java, BASIC, javaScript, LISP, shell, perl, ruby, python, PHP, etc. If the verification authentication result is passed, the security verification voice gateway sends a voice call request to the SIP server, namely the voice call request is directly released. If the verification authentication result is not passed, the security verification voice gateway sends a call blocking response to the terminal equipment.

After step S310, step S320 is performed: when the SIP server determines that the voice call request does not belong to the call in the network, the SIP server generates a path monitoring request according to call path information of the voice call request.
The embodiment of step S320 described above is, for example: if the SIP server determines that the voice call request belongs to the call in the network, the voice call request is directly released; only when the voice call request is determined not to belong to the call in the network, searching call path information corresponding to the voice call request in a database or a file system, generating a path monitoring request according to the call path information of the voice call request, and sending the path monitoring request to a safe operation and maintenance platform. Among the databases that may be used include, but are not limited to: a memory database, a relational database and a non-relational database; an in-memory database that may be used is for example: memcached and Redis, etc., relational databases that can be used are, for example: mysql, postgreSQL, oracle and SQLSever, etc., non-relational databases that may be used include: grakn database, neo4j graph database, hadoop subsystem HBase, mongoDB, couchDB, etc.
After step S320, step S330 is performed: the SIP server sends a path monitoring request to the security operation and maintenance platform so that the security operation and maintenance platform monitors call path information in the path monitoring request to obtain and return a path monitoring result.
The implementation principle and implementation of this step S330 are similar to those of the step S150, and thus, the implementation principle and implementation thereof will not be described again here, and reference may be made to the description of the step S150 if it is not clear.
After step S330, step S340 is performed: and the SIP server receives the path monitoring result sent by the security operation and maintenance platform and judges whether the path monitoring result passes or not.
After step S340, step S350 is performed: if the path monitoring result is passed, the SIP server releases the voice call request.
After step S340, step S360 is performed: if the path monitoring result is not passed, the SIP server sends a call blocking response to the terminal equipment through the security check voice gateway.
