Description

Voice processing method, related equipment and storage medium

Technical Field

The present invention relates to the field of network security, and in particular, to a voice processing method, related devices, and a storage medium.

Background

In the bad information management of mobile communication, the problem of difficult judgment, difficult evidence collection and the like exists in the management of voice information. With the continuous expansion of the domestic voice private line service, the continuous existence of foreign number changing platforms and other factors, the phenomenon that false numbers are formed after number changing to dial harassing calls appears in large quantity, so that the private line service and the internetwork (international) service are falsely changed in number, and the fraud is carried out on users.

With the advent of 5G networks, 5G network elements are no longer physical devices based on a dedicated telecommunications Architecture (e.g., Advanced Telecommunications Computing Architecture (ATCA)), but are instead converted into functional software after virtualization based on a general purpose computer server; meanwhile, the interfaces between the network elements are no longer fixed binding relationships, but are software functional interfaces based on Internet Technology (IT) services. Because security vulnerabilities of the IT system technology cannot be avoided, and some potential safety hazards in software operation cannot be thoroughly eliminated, a great number of 5G network element functions face potential vulnerability risks after network element software is implemented, and the IT system technology becomes a huge security challenge. The processing of 5G voice by network virtualization also brings technical challenges, and the traditional tandem processing mode is no longer applicable in a 5G virtualized core network; for the users who are out of country at home, the users cannot be handled at the international gateway.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

FIG. 1 is a schematic structural diagram of a system architecture applied to a speech processing method according to an embodiment of the present invention; as shown in fig. 1, the system includes a centralized processing platform 11 and a speech processing platform 12; the centralized processing platform 11 implements functions of unified management, issuing of processing policies, issuing of intervention instructions, and the like. The voice processing platform 12 may be generally deployed in an IP Multimedia System (IMS) network or a virtual IMS (IMS) network of an operator, and is configured to perform functions of traffic analysis, processing, blocking, and data reporting. The centralized processing platform 11 may also be deployed in the IMS network of the operator, or in a proprietary network of some specific enterprise or department.

The voice processing platform 12 is divided into a service layer and a capability layer according to the principle of capability opening and layered decoupling, and the service layer and the capability layer can be decoupled by an interface; illustratively, communication between the business layer and the capability layer can be realized by means of RESTful. The service layer may be implemented by a service server, and the capability layer may be implemented by an access capability network element, that is, the voice processing platform 12 may include a service server 121 and an access capability network element 122. The service server provides policy judgment, controls the release or blocking of the call, and informs the access capability network element to perform service processing such as drainage sampling, voice detection and the like. The access capability network element provides a call event notice of voice (or video), and executes services such as media stream guidance sampling, voice detection and the like according to the indication of the service server.

Alternatively, the voice processing platform may be implemented by using a virtualized network element device, that is, the service server and the access capability network element may be implemented by virtual devices (e.g., software) in two different physical devices (e.g., servers), or by two virtual devices (e.g., software) in one physical device (e.g., server).

The access capability network element 122 may transmit a Session Initiation Protocol (SIP) message with a Call Session Control Function (CSCF); the CSCF may be an Interrogating CSCF (I-CSCF) or a Serving CSCF (S-CSCF). The access capability network element 122 may Transport Real-time Transport Protocol (RTP) messages with the SBC or IM-MGW.

Based on the above system configuration, the following embodiments of the present invention are proposed.

The embodiment of the invention provides a voice processing method. FIG. 2 is a first flowchart illustrating a voice processing method according to an embodiment of the present invention; as shown in fig. 2, the method includes:

step 101: a first network device receives a call request message, wherein the call request message comprises a calling number and a called number;

step 102: judging whether the calling number meets a preset trigger condition or not;

step 103: under the condition that the calling number is judged to meet the preset triggering condition, the calling request message is forwarded to an access capability network element; and the access capability network element is used for acquiring a call control strategy aiming at the call request message from a service server and processing a call event corresponding to the call request message according to the call control strategy.

In this embodiment, the first network device may be an S-CSCF; specifically, the S-CSCF may be an S-CSCF at the location of the called terminal. It can be understood that, after the calling terminal initiates a call request, the call request goes through a Proxy CSCF (P-CSCF, Proxy CSCF), an S-CSCF at the location of the calling terminal, an I-CSCF, and other network elements to an S-CSCF at the location of the called terminal. It can be understood that the call voice processing is triggered by the S-CSCF at the location of the called terminal, and the Home Subscriber Server (HSS) in each area subscribes to the voice processing service for the terminal in the area. Optionally, the calling terminal may be a terminal of a VoLTE, VoNR, IMS network.

In some optional embodiments of the present invention, the determining whether the calling number meets a preset trigger condition includes: judging whether the calling number is an inter-provincial number or an international number; determining that the calling number meets a preset triggering condition under the condition that the calling number is judged to be an inter-provincial number or an international number; or, judging whether the calling number is an intra-provincial roaming number; and under the condition that the calling number is judged to be the intra-provincial roaming number, determining that the calling number meets a preset triggering condition.

In this embodiment, the preset trigger condition may include that the calling number is an inter-provincial number or an international number, or that the calling number is an intra-provincial roaming number. The inter-provincial number is a number where the home location does not belong to the location of the first network device, and the international number is a number where the home location does not belong to the country, that is, a number of another country. The inter-provincial roaming number is a number which belongs to the location of the first network device but is not currently located at the location of the first network device, and may also be referred to as an inter-provincial roaming number.

In practical applications, whether the preset trigger condition is met can be determined according to a specific field in the call request message. For example, if the call request message is an Invite message, it may be determined whether the call request message is an inter-provincial number or an international number according to a "home provincial name" in a P-Asserted-Identity field of an SIP header in the Invite message, and if the home provincial name is not consistent with the current provincial name, it may be determined that the call number is an inter-provincial number or an international number; if the attribution domain name is consistent with the province, judging whether the attribution domain name is consistent with the province name according to 'attribution province name' in sbc-domain in a P-Access-Network-Info header field in the Invite message, and if the attribution domain name is not consistent with the province name, determining that the calling number is an intra-province roaming number.

In some optional embodiments of the invention, the method further comprises: the first network equipment receives the call request message forwarded by the access capability network element, and establishes a communication link between a calling terminal and a called terminal based on the call request message; the first network equipment forwards the new called media resource information sent by the access capability network element to the calling terminal and forwards the new calling media resource information sent by the access capability network element to the called terminal; the new called media resource information is used for the second network equipment to forward the first voice information carrying the new called media resource information to the access capability network element after receiving the first voice information sent by the calling terminal; and the new calling media resource information is used for forwarding the second voice information carrying the new calling media resource information to the access capability network element after the second network device receives the second voice information sent by the called terminal.

In this embodiment, the access capability network element modifies media resource information of a calling terminal and a called terminal (the calling terminal corresponds to calling media resource information, and the called terminal corresponds to called media resource information), and sends updated new calling media resource information to the called terminal through the first network device, so that the calling terminal carries new called media resource information in later-sent first voice information, after the first voice information sent by the calling terminal reaches the second network device, the second network device can send the first voice information to the access capability network element according to the new called media resource information carried in the first voice information, and the access capability network element performs sampling detection on the first voice information, instead of directly transmitting the first voice information to the called terminal in a conventional process. Similarly, the access capability network element sends the updated new calling media resource information to the called terminal through the first network device, so that the called terminal carries the new calling media resource information in the second voice information sent later, after the second voice information sent by the called terminal reaches the second network device, the second network device can send the second voice information to the access capability network element according to the new calling media resource information carried in the second voice information, and the access capability network element performs sampling detection on the second voice information, rather than directly transmitting the second voice information to the calling terminal in a conventional process.

Based on the foregoing embodiments, the embodiment of the present invention further provides a speech processing method. FIG. 3 is a flowchart illustrating a second speech processing method according to an embodiment of the present invention; as shown in fig. 3, the method includes:

step 201: an access capability network element receives a call request message sent by first network equipment, wherein the call request message comprises a calling number and a called number;

step 202: sending a first call event notification message to a service server, wherein the first call event notification message comprises the calling number and the called number; the first call event notification message is used for the service server to determine call control information based on the calling number and/or the called number;

step 203: and receiving call control information aiming at the call request message and sent by the service server, and processing a call event corresponding to the call request message based on the call control information.

In this embodiment, the first network device may be an S-CSCF (called S-CSCF for short) where the called terminal is located, and the first network device sends the call request message to the access capability network element after receiving the call request message initiated by the calling terminal, instead of sending the call request to the called terminal in a conventional processing flow, and processes a call event corresponding to the call request message through the access capability network element based on a control policy provided by the service server.

The access capability network element sends a calling number and a called number carried in a call request message to a service server through a first call event notification message; a processing strategy issued by a centralized processing platform is obtained in advance in a service server; the processing policy may include a call control policy corresponding to each number, where the call control policy includes whether to perform a stream guidance processing of the media stream (i.e., to perform sampling detection on voice information of the calling terminal and/or the called terminal); the call control policy may further include a drainage processing manner of the media stream, a processing manner in the case that the media stream satisfying the preset condition is detected, and the like.

In some optional embodiments of the present invention, the processing, based on the call control information, a call event corresponding to the call request message includes: the access capability network element forwards the call request message to the first network equipment based on a continuous call control instruction in the call control information, wherein the call request message is used for establishing a communication link between a calling terminal and a called terminal; after a communication link between the calling terminal and the called terminal is established, the access capability network element receives first voice information of the calling terminal and second voice information of the called terminal sent by second network equipment under the condition that the call control information comprises indication information for guiding media streams, and detects the first voice information and the second voice information to obtain a detection result; and initiating call control to the calling terminal and/or the called terminal based on the detection result.

Step 505 to step 506, the access capability network element forwards the call request message to the called S-CSCF, and sends the call request message to the called UE via the called S-CSCF, and the called UE returns 183 message, and forwards the call request message to the access capability network element via the called S-CSCF.

Step 507, the access capability network element saves the called media resource information in the 183 message, and updates the called media resource information, that is, reallocates the available media resources to replace the called media resource information in the 183 message, so as to obtain the new called media resource information. The new called media resource information is used to indicate that the voice information of the called UE needs to be detected after the access capability network element receives the voice information.

Step 508-step 509, the access capability network element sends the 183 message to the called S-CSCF, and the called S-CSCF forwards the 183 message to the calling UE, and the calling UE sends a PRACK message response 183 message, and the called UE replies a 200OK message to confirm the PRACK message.

Step 510, the calling UE sends an UPDATE (UPDATE) message, which is obtained by the called S-CSCF and forwarded to the access capability network element after passing through multiple network elements.

Step 511, the access capability network element saves the calling media resource information in the UPDATE message, UPDATEs the calling media resource information, reallocates the available media resources to replace the calling media resource information in the UPDATE message, and obtains the new calling media resource information.

The service server initiates a call control instruction for blocking to the access capability network element, the control parameter is EndCall, and the access capability network element sends Bye messages to the calling UE and the called UE respectively to release the call.

Step 613-step 616, in the above four kinds of scenarios, after the service server receives any notification message, it can initiate the operation of muting the calling and called parties according to the configured policy. The service server initiates a call control instruction for playing silence, the control parameter is MuteCall, and the access capability network element modifies the media streams sent to the calling UE and the called UE into silence packets respectively.

Step 617-step 618, hanging up between the calling UE and the called UE, completing signaling interaction of Bye/200OK, and after the call is finished, the access capability network element sends a call event notification message to the service server, where the message includes information such as a call Release (Release) identifier and a sampled voice file path of the calling and called sides.
