Description

False caller identification method and device, electronic equipment and storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a false caller identification method and apparatus, an electronic device, and a storage medium.

Background

The calling number display service, namely the caller identification service, is a basic function of a telephone network, and the wide use of the calling number display service brings great convenience to users. However, some lawbreakers, using new network technologies or existing vulnerabilities of gateway devices, artificially modify the calling number to a social public service number such as 110, an operator service number such as 10086 or other user numbers, and perform illegal activities such as harassment and telephone fraud to users. Therefore, effective measures are urgently needed to be taken to monitor the calling number so as to intercept false calling numbers.

However, the prior art identification process for false callers includes: a calling Subscriber initiates a call, a gateway triggers a Service Control Point (SCP), the SCP sends an Arbitrary Time Inquiry (ATI) message to a Home Location Register (HLR), the HLR receives the ATI message and sends a Provide Subscriber Information (PSI) message to a Visitor Mobile Switching Center (VMSC)/Visitor Location Register (VLR) to acquire the idle state of the calling Subscriber, and determines whether the calling Subscriber is a false calling Subscriber by determining whether the idle state of the calling Subscriber is idle, wherein the ATI message and the PSI message both contain identification Information of the calling Subscriber.

However, this method can only be applied to calls in a single Circuit Switched (CS) domain, and cannot be applied to calls in a Packet Switched (PS) domain, or calls in both PS and CS domains. For calls in the PS domain or calls in the presence of both the PS domain and the CS domain can only be connected, so that lawless persons harass the user by using false calling numbers, implement telephone fraud and the like, loss is caused to the user, and user experience is influenced. How to support the identification of false callers in the CS domain and the PS domain at the same time becomes a problem to be solved urgently.

Specifically, whether the IMS corresponding to the calling user is subscribed may be represented by a value of an IP Multimedia Public Identity (IMPU) in the UDA message, where a value of 5001 for the IMPU indicates that the IMS is not subscribed, and a value of 2001 for the IMPU indicates that the IMS is subscribed; whether the IMS corresponding to the calling User is registered or not can be represented by a value of an IP multimedia subsystem User State (IMS User State) in the UDA message, wherein the IMS User State value is 0 to represent that the IMS is not registered, and the IMS User State value is 1 or 2 or 3 to represent that the IMS is registered; whether the T-ADS corresponding to the calling subscriber supports the PS domain or not can be represented by the value of the T-ADS in the UDA message, wherein the value of the T-ADS is 1 to represent that the PS domain is supported, and the value of the T-ADS is 0 or 2 to represent that the PS domain is not supported.

When the domain where the calling user is located is determined, the determination is carried out according to the judgment results of whether the IMS signs a contract or not, whether the IMS signs a register or not and whether the T-ADS supports the PS domain or not, if yes, the calling user is determined to be in the PS domain, and if any one of the IMS signs a contract or not, the T-ADS supports the PS domain, the calling user is determined to be in the CS domain.

Fig. 2 is a schematic diagram for determining a domain where a calling subscriber is located according to a UDA message sent by an HSS according to an embodiment of the present invention. Specifically, the UDA message returned by the HSS comprises information of IMPU, IMS User State and T-ADS, wherein if the value of IMPS is 5001, the IMS is not signed, the value of IMPS is 2001, the IMS is signed, the value of IMS User State is 0, the IMS is not registered, the value of IMS User State is 1, 2 or 3, the IMS is registered, the T-ADS is 1, the T-ADS supports the PS domain, can be expressed as IMS-VOICE-OVER-PS-SUPPORTED, T-ADS is 0 to express that T-ADS does not support PS domain, can be expressed as IMS-VOICE-OVER-PS-NOT-SUPPORTED, TADS is 2 means that T-ADS does NOT support PS domain, may be denoted as IMS-VOICE-OVER-PS-supported-UNKNOWN, whether the TADS supports the PS domain or not is unknown under the condition, and for convenience of subsequent identification, the T-ADS is determined not to support the PS domain; the information whether the IMS is registered is Any, which indicates that whether the IMS is registered is not limited, and the information of the T-ADS is Any, which indicates that whether the IMS supports the PS domain is not limited.

When the UDA message returned by the HSS is case 1: the IMS does not sign a contract, the domain where the calling user is located is determined to be a CS domain, and the domain for inquiring the busy and idle state of the calling user is determined to be the CS domain; when the UDA message returned by the HSS is case 2: the IMS is signed and not registered, the domain where the calling user is located is determined to be a CS domain, and the domain for inquiring the busy and idle state of the calling user is determined to be the CS domain; when the UDA message returned by the HSS is case 3: IMS has signed and registered, T-ADS does not support PS domain, confirm the domain that the caller belongs to is CS domain at present, carry on caller busy and free state inquiry domain for CS domain; when the UDA message returned by the HSS is case 4: IMS has signed and registered, T-ADS supports PS domain, confirms the domain where the calling user locates at is PS domain, the domain that inquires the busy/idle state of the calling user is PS domain; when the UDA message returned by the HSS is case 5: in other cases, that is, in cases other than the above case 1, case 2, case 3, and case 4, it is determined that the domain where the calling user is currently located is the CS domain, and the domain where the calling user is in the busy-idle state query is the CS domain.

S104: inquiring a Policy and Charging Rules Function (PCRF) about the busy-idle state of the calling subscriber, and if the busy-idle state of the calling subscriber is idle, determining that the calling subscriber of the call is a false calling subscriber.

The PCRF is a policy and charging control policy decision point of the service data stream and the IP bearer resource, and can determine the busy and idle state of the user by inquiring whether the user is in the voice bearer or not, if the user is in the voice bearer, the busy and idle state of the user is determined to be busy, and if the user is not in the voice bearer, the busy and idle state of the user is determined to be idle. Of course, the busy/idle state of the user can also be determined by inquiring whether the voice service of the user is being charged, if the voice service of the user is being charged, the busy/idle state of the user is determined to be busy, and if the voice service of the user is not being charged, the busy/idle state of the user is determined to be idle.

Specifically, the SCP may send a first message including the identification information of the calling party to the PCRF, receive a second message including a busy-idle state of the calling party replied by the PCRF, and determine that the calling party of the call is a false call if the busy-idle state of the calling party is idle, which indicates that the calling party is not in call access or in call connection.

And if the busy-idle state of the calling subscriber is busy, determining that the calling subscriber is not a false calling subscriber.

S105: and determining that the calling user is in a Circuit Switching (CS) domain, inquiring a Home Location Register (HLR) about the busy-idle state of the calling user, and if the busy-idle state of the calling user is idle, determining that the calling user of the call is a false calling.

Specifically, an ATI message containing the identification information of the calling subscriber is sent to an HLR, the HLR sends a PSI message to a VMSC/VLR after receiving the ATI message to acquire the state of the calling subscriber, and sends a response (PSI _ ask) message which is replied by the VMSC/VLR and provides subscriber information to an SCP, wherein the PSI _ ask message comprises the busy and idle state of the calling subscriber, and the SCP determines that the calling subscriber of the call is a false calling subscriber according to the busy and idle state of the calling subscriber if the busy and idle state of the calling subscriber is idle, which indicates that the calling subscriber is not in call access or call connection.

In the embodiment of the invention, whether the calling user of the call is in the PS domain is judged by judging whether the IMS corresponding to the calling user signs a contract and registers and whether the T-ADS supports the PS domain, if so, the calling user of the call is determined to be in the PS domain, the busy-idle state of the calling user is inquired by the PCRF, otherwise, the calling user of the call is determined to be in the CS domain, the busy-idle state of the calling user is inquired by the HLR, and if the busy-idle state of the calling user is idle, the calling user of the call is determined to be a false calling, so that the false calling identification in the CS domain and the PS domain is simultaneously supported, the loss of the user is avoided, and the user experience is improved.

Example 2:

in order to improve the accuracy of false caller identification, on the basis of the above embodiment, in an embodiment of the present invention, the querying the PCRF about the busy-idle state of the calling subscriber includes:

sending a User-quality-of-service-Request (UQR) message including the calling subscriber identification information to the PCRF;

receiving a User-Qos-Answer (UQA) message sent by the PCRF, wherein the UQA message carries a value of a Qos Class Identifier (QCI) corresponding to the calling subscriber, and the value of the QCI is 1 to identify that the busy/idle state of the calling subscriber is busy, and the value of the QCI is not 1 to identify that the busy/idle state of the calling subscriber is idle.

The PCRF is a policy and charging control policy decision point for Service data streams and IP bearer resources, and can control Quality of Service (QoS) for users and services, thereby providing differentiated services for users. The QoS Class Identifier (QCI) is one of the most important QoS parameters carried by an Evolved Packet System (EPS), and represents the QoS characteristics that the EPS should provide for a Service Data Flow (SDF). In the characteristics of 9 standard QCIs of Long Term Evolution (LTE) system given in the section of 3GPP 23.203 protocol 6.1.7.2, it is indicated that when a voice call service is performed, the value of QCI is 1, which indicates that a voice bearer is established and a user is in call access or call connection. That is, when the value of QCI allocated to the voice call service of the user by the PCRF is 1, it indicates that the busy-idle state of the user is busy.

Specifically, the SCP sends UQR messages containing identification information of the calling party to the PCRF, the PCRF replies UQA messages containing the QCI value of the calling party to the SCP after receiving UQR messages containing identification information of the calling party sent by the SCP, and if the QCI value of the calling party is 1 in the UQA messages, it is determined that the busy and idle state of the calling party is busy. Otherwise, determining the busy-idle state of the calling user as idle.

Table 1 shows information of key information elements in UQR messages according to an embodiment of the present invention.

TABLE 1

As shown in table 1, the Information Element (Information Element) in the UQR message includes a Subscription Identity (Subscription-ID), Requested QoS data (Requested QoS data), and an Identity of the Server (Server Identity), and the corresponding Presence requirements (Presence Requirement) are all Mandatory (database), and Information elements indicating that the Subscription-ID, the Requested QoS data, and the Server Identity are all critical, where the summary of the Subscription-ID is a user identifier, which may be a user phone number, the summary of the Requested QoS data is QoS data that needs to be queried, and the summary of the Server Identity is a PCRF Identity.

Table 2 shows information of key information elements in a UDA message according to an embodiment of the present invention.

TABLE 2

As shown in table 2, the Information Element in the UQA message includes a Subscription-ID and a QoS value (EPS-Bearer-QoS) of the EPS Bearer, and the corresponding Presence requirements are both directory, which indicates that the Subscription-ID and the EPS-Bearer-QoS are both critical Information elements, where the brief description of the Subscription-ID is a user identifier, which may be a user phone number, and the brief description of the EPS-Bearer-QoS is a returned QoS value.

Example 3:

in order to improve the efficiency of false caller identification, on the basis of the above embodiment, in an embodiment of the present invention, before sending the UDR message including the identification information of the calling subscriber to the HSS, the method further includes:

if not, the subsequent steps are carried out.

In the embodiment of the present invention, a blacklist is set in advance for a false caller frequently used by a lawbreaker, for example: callers with caller number 12314 who are similar to consumer hotline 12315 are added to the blacklist, callers with caller number 10056 who are similar to mobile service hotline 10086 are added to the blacklist.

Specifically, before sending the UDR message including the identification information of the calling subscriber to the HSS, it is determined whether a blacklist includes the identification information of the calling subscriber, if the blacklist includes the identification information of the calling subscriber, it is indicated that the calling subscriber of the call is a false calling, and if the blacklist does not include the identification information of the calling subscriber, a subsequent step of sending the UDR message including the identification information of the calling subscriber to the HSS is performed.

Example 4:

on the basis of the foregoing embodiments, in an embodiment of the present invention, to improve accuracy of false caller identification, before determining that a caller is behind a CS domain and if a busy/idle state of the caller is idle, determining that the caller of a call is a false caller, the method further includes:

inquiring the position of the calling subscriber from an HLR;

judging whether the position is within a preset position range or not;

if yes, the subsequent steps are carried out.

In the embodiment of the present invention, the preset position range is determined according to the service range of the SCP, and when the calling party of the call is not within the service range of the SCP, there may be a situation that the calling party performs forwarding or call forwarding, and at this time, although the calling party is calling, the busy-idle state corresponding to the calling party may still be idle, and thus the calling party is determined to be a false calling party.

In order to guarantee the rights and interests of the users, false caller identification is not carried out on the calls corresponding to the calling users which are not in the preset position range. For example: and if the SCP is a China mobile SCP and the service range corresponding to the SCP is in China, the preset position range aiming at the SCP is in China, and the calling of the calling user, which is not in China, is not identified by the false calling.

Example 5:

to further ensure the accuracy of false caller identification, on the basis of the foregoing embodiments, in an embodiment of the present invention, before sending, to the HSS, a UDR message including identification information of a calling party according to the calling party of a call, the method further includes:
