The short number refers to a 3-bit or 4-bit number given by an operator after joining services such as a group network or a family affinity network, and is only used for calling in the group network or the family affinity network, and the calling in the network is free without dialing other numbers.

The foregoing is a description of some concepts designed by the embodiments of the present invention, and is not described in detail below.

As background technology, the number-carrying and network-transferring is to replace one operator without changing the number of the mobile phone and enjoy the services provided by the operator. VoLTE VPN is a service for realizing functions such as short number mutual dialing by establishing a virtual private network, providing voice call for the internal members of group clients by using abbreviated dialing, special numbering plan and the like.

For ease of understanding, voLTE VPN routing calls are described below by way of example.

Taking an example that a user a in a networking group 1 established by a connected user who has opened a VoLTE VPN service calls a user B, where the short number "75231" of the user B may be the connected user (i.e., the user in the networking group 1) or the user who carries a number to transfer to the other network from the connected user, as shown in fig. 1, the user a initiates a call request and transmits the call request to an S-CSCF network element; after receiving the call request, the S-CSCF network element initiates a trigger request to the virtual private network platform, and after receiving the trigger request, the virtual private network platform converts the short number '75231' into a long number, and then sends the long number to a telephone number mapping and domain name system (e.164 number and DNS, ENS) network element through the S-CSCF network element for route inquiry and matching with the next hop route; then the ENS network element routes the call to a first boundary connection control function (interconnect border control function, IBCF) network element according to the matched next hop, then the first IBCF network element calls to a second IBCF network element, then calls to an IMS network, and finally calls to a user B through the IMS network.

In addition, the user B can dial the trombone of the user A, and then the virtual private network platform converts the trombone into the short number so as to call the user A through the virtual private network platform.

It should be noted that, when the user B is a connected user, the user a calls the user B and can normally call through the virtual private network platform; in the case that the user B is a user from the connected user to the other network through the number portability, the virtual private network platform still retains the user data and the like of the user from the number portability to the other network in the process of the number portability, so that the call can still be successful.

As can be seen from the above, in the related art, the virtual private network platform cannot identify the operator network to which the called terminal belongs, and cannot suppress the situation that the user of his network is called through the virtual private network platform, thereby generating a virtual private network call across operators. From the point of view of the bill, the situation easily causes inaccurate bill data record, and cannot truly reflect the communication condition of the user, thereby affecting the reasonability of charging of operators.

Therefore, the application adjusts the rule of triggering the virtual private network platform and increases the service judgment of the called terminal, thereby realizing the data judgment of the cross-network service of the virtual private network, ensuring that the call of the normal user is not affected, effectively reducing the call condition caused by the junk data and avoiding the call problem caused by the platform data problem. Besides, the application improves the network quality and user experience of the operators, ensures the correctness of the call ticket data and enhances the charge rationality of the operators.

Specifically, the embodiment of the application provides a call ticket data recording method, which has the following ideas: firstly, the application obtains the user information of the called terminal from the data management network element according to the number information of the called terminal carried in the call request by receiving the call request, thereby ensuring the accuracy of the user information; and screening telephone traffic data generated in the process that the calling terminal and the called terminal do not communicate through the virtual private network platform according to the number information and the user information, and recognizing and screening the target telephone traffic data of the calling terminal and the called terminal which do not communicate through the virtual private network platform by combining the number information and the user information, so that the telephone traffic data in a specific scene is more accurately recognized and recorded, the accuracy of the telephone traffic data is improved, a more reasonable basis is provided for subsequent charging and billing, and the rationality of the billing is further enhanced.

Referring to fig. 3, a call ticket data recording method is provided for an embodiment of the present application, and the method can be applied to the S-CSCF network element shown in fig. 2, and includes the following steps S101 to S104.

S101, receiving a call request of a calling terminal.

In some embodiments, the calling terminal is provisioned with a virtual private network service.

In some embodiments, the operator to which the calling terminal belongs is the target operator. Wherein the target operator is configured to receive and process the user request during the communication. Exemplary, target operators include, but are not limited to, the following: a corporate operator, a mobile operator, or a telecommunications operator, etc.

In some embodiments, the call request includes number information of the called terminal.

The call request refers to a request sent by a party initiating communication (i.e. a calling terminal) to a network, and is used for requesting to establish communication connection with a called terminal. In the embodiment of the application, the call request is initiated by the calling terminal by dialing the number information of the called terminal.

In some embodiments, the calling terminal initiates the call request by dialing the number information of the called terminal; then the calling terminal sends the call request to the P-CSCF network element for preliminary treatment; the P-CSCF network element forwards the call request to the corresponding I-CSCF network element according to the route information, and the I-CSCF network element inquires the data management network element to acquire the address of the S-CSCF network element registered by the calling terminal and determine the position of the S-CSCF network element; and finally, the I-CSCF network element sends the call request to the S-CSCF network element for subsequent processing and session control.

In some embodiments, the S-CSCF network element may filter out call requests of calling terminals of non-target operators in case the operator to which the calling terminal belongs is not limited to the target operator.

In particular, the S-CSCF network element may implement filtering call requests of calling terminals of non-target operators by adding service triggering rules (SERVICE INITIAL FILTER CRITERIA, SIFC) and protocols or rules (IFCs) of the control interface.

Wherein SIFC is a triggering rule for deciding when to start to collude a specific service, and in the embodiment of the present application, it is used to determine whether to trigger a virtual private network platform in the process that the calling terminal calls the called terminal; IFCs are conditions or rules that trigger SIFC, SIFC being triggered when certain IFC conditions are met.

In some embodiments, the IFCs include service trigger points (SPTs) that may determine and filter the number information of the calling terminal, the bit length of the number information, and the SIP message header field.

After receiving a call request of a calling terminal, the SPT of the S-CSCF network element may determine the bit length of the number information of the calling terminal and the SIP message header field, and filter the call request initiated by the calling terminal of the non-target operator, so that the called terminal is not called through the virtual private network platform.

In some embodiments, the S-CSCF network element may further determine whether the operator to which the calling terminal belongs is a target operator by determining whether the preamble of the calling terminal is a target preamble corresponding to the target operator, and filter out a call request initiated by the calling terminal of which the operator to which the calling terminal belongs is not the target operator, so that the called terminal is not called through the virtual private network platform.

In some embodiments, the SIP protocol includes INVITE signaling for inviting the called terminal to join the session.

For example, when the calling terminal wants to establish a session with the called terminal, the calling terminal will send an INVITE signaling to the called terminal, and the called terminal may choose to accept or reject the INVITE signaling, where the called terminal can join the session only if the called terminal accepts the INVITE signaling.

In summary, adding the service triggering rule to the S-CSCF network element may be implemented by adding the SPT to the S-CSCF network element, and it may be understood that, since the SPT may be flexibly adjusted according to the service requirement, so as to meet the service requirements in different scenarios, the security and stability of the system may be improved by adding the SPT.

S102, based on the number information, acquiring the user information of the called terminal from the data management network element.

The user information is used for representing information of an operator to which the called terminal belongs.

For example, assuming that the subscriber information of the called terminal a is information of the a operator, it indicates that the operator to which the called terminal a belongs is the a operator.

The subscriber information may include, for example, a preamble of the called terminal. Wherein the preamble is a code or number for representing or classifying the data element. In the embodiment of the application, the preamble is used for identifying the operator to which the terminal side equipment belongs.

In some embodiments, the data management network element may be an HSS network element or a UDM network element, for storing user information of an operator, etc.

In some embodiments, as shown in fig. 4, the above step S102 may be implemented as the following steps S1021 to S1022.

S1021, based on the number information, a first message is sent to the data management network element, wherein the first message is used for requesting the data management network element to inquire the user information.

The first message includes number information, which is used to instruct the data management network element to query the user information corresponding to the number information.

In some embodiments, after the S-CSCF network element receives the call request of the calling terminal, the SPT sends a first message to the data management network element in response to the call request, and after the data management network element receives the first message, determines user information corresponding to the number information from the data stored in the data management network element and sends the user information to the S-CSCF network element, for example, the following step S1022 is performed.

It should be noted that, there is a correspondence between the number information and the user information, and the number a, the number b, and the number c are exemplified as shown in table 1 below.

TABLE 1

S1022, receiving the second message sent by the data management network element.

Wherein the second message includes user information.

It can be understood that the application can rapidly locate the user information corresponding to the number information in the data management network element based on the number information and acquire the user information, thereby improving the response speed and efficiency of the communication service; in addition, the user information is directly obtained from the data management network element according to the number information, so that the accuracy of the user information can be ensured, and the reliability of the communication service is improved.

S103, determining whether the calling terminal can call the called terminal through the virtual private network platform according to the user information and the number information.

In some embodiments, in case the first condition is met, it is determined that the calling terminal is capable of calling the called terminal through the virtual private network platform. Wherein the first condition comprises: the operators to which the calling terminal and the called terminal belong are target operators; the calling terminal and the called terminal both open the virtual private network service.

It should be noted that, the S-CSCF network element and the virtual private network platform may determine and filter the call that does not satisfy the first condition, and under the condition that the calling terminal and the called terminal do not satisfy the first condition, the calling terminal is prevented from calling the called terminal through the virtual private network platform, so as to ensure that both the calling terminal and the called terminal that can make the call through the virtual private network platform satisfy the first condition.

In some embodiments, in the case that the calling terminal has a virtual private network service and the operator to which the calling terminal belongs is the target operator, if it is determined whether the calling terminal can call the called terminal through the virtual private network platform, it is only necessary to determine whether the operator to which the called terminal belongs is the target operator and whether the called terminal has a virtual private network service, so the step S103 may be implemented as steps S1031 to S1033 shown in fig. 5.

S1031, determining whether the operator to which the called terminal belongs is a target operator according to the user information.

In some embodiments, step S1031 may be embodied as: the S-CSCF network element determines whether the operator to which the called terminal belongs is a target operator according to whether the pre-insertion code of the called terminal is the target pre-insertion code corresponding to the target operator.

For example, assuming that the operator a is a target operator, after the pre-insert code of the operator a is 1234, the s-CSCF network element obtains the pre-insert code of the called terminal, it is determined whether the operator to which the called terminal belongs is the target operator by determining whether the pre-insert code of the called terminal is 1234.

It should be noted that, in the case that the pre-insertion code of the called terminal is the target pre-insertion code, determining the operator to which the called terminal belongs as the target operator; and in the case that the pre-inserted code of the called terminal is not the target pre-inserted code, determining that the operator to which the called terminal belongs is not the target operator.

It can be understood that the method for determining whether the operator to which the called terminal belongs is the target operator according to the preamble of the called terminal has higher accuracy and faster efficiency compared with other methods.

S1032, under the condition that the operator to which the called terminal belongs is a target operator, the number information is sent to the virtual private network platform, so that the virtual private network platform determines whether the called terminal opens the virtual private network service according to the number information.

In some embodiments, the vpn platform includes a vpn database, where the vpn database is configured to store number information of a terminal side device that opens a vpn service, a short number corresponding to the number information, subscription data corresponding to the number information, and so on. The subscription data refers to a certificate for enabling the terminal side equipment to open the virtual private network service.

As a possible implementation manner, in the case that the operator to which the called terminal belongs is the target operator, the S-CSCF network element sends the number information to the virtual private network platform, and the virtual private network platform queries whether subscription data corresponding to the number information exists in the virtual private network database according to the number information so as to determine whether the called terminal opens the virtual private network service.

For example, in the case that subscription data corresponding to the number information exists in the virtual private network database, the virtual private network platform determines that the called terminal opens the virtual private network service; under the condition that the subscription data corresponding to the number information does not exist in the virtual private network database, the virtual private network platform determines that the called terminal does not open the virtual private network service.

As another possible implementation manner, in the case that the operator to which the called terminal belongs is the target operator, the S-CSCF network element sends the number information to the virtual private network platform, and the virtual private network platform queries whether the short number corresponding to the number information exists in the virtual private network database according to the number information to determine whether the called terminal opens the virtual private network service.

For example, in the case that a short number corresponding to the number information exists in the virtual private network database, the virtual private network platform determines that the called terminal opens a virtual private network service; under the condition that the short number corresponding to the number information does not exist in the virtual private network database, the virtual private network platform determines that the called terminal does not open the virtual private network service.

S1033, under the condition that the called terminal does not open the virtual private network service, determining that the calling terminal cannot call the called terminal through the virtual private network platform.

It can be understood that, in the case where the called terminal does not open the virtual private network service, the called terminal does not satisfy the condition that both the calling terminal and the operator to which the called terminal belongs are target operators and both the calling terminal and the called terminal open the virtual private network service, and therefore, the calling terminal cannot call the called terminal through the virtual private network platform.

And S104, under the condition that the calling terminal does not call the called terminal through the virtual private network platform, recording target call ticket data, wherein the target call ticket data are telephone traffic data generated in the process that the calling terminal and the called terminal do not call through the virtual private network platform.

The target call ticket data is used for recording basic information of a calling terminal calling a called terminal, for example: the start time, duration, end time of call, calling terminal, called terminal, etc.

In some embodiments, when the calling terminal does not call the called terminal through the virtual private network platform, the virtual private network platform does not generate the target call ticket data corresponding to the call, so that the target call ticket data is not recorded; but even if the calling terminal calls the called terminal without passing through the virtual private network platform, the S-CSCF network element will still generate the target call ticket data corresponding to the call and record the target call ticket data.

In some embodiments, in the case that the calling terminal calls the called terminal through the virtual private network platform, both the virtual private network platform and the S-CSCF network element generate the target call ticket data corresponding to the call, and record the target call ticket data.

In some embodiments, the S-CSCF network element or the virtual private network platform generates the target call ticket data by detecting the call request and the response information, and when the S-CSCF network element or the virtual private network platform detects an event such as the establishment or the release of the call request, the S-CSCF network element or the virtual private network platform records the event; in addition, the S-CSCF network element or the virtual private network platform can also configure a corresponding data recording mechanism and a database to store the target call ticket data for subsequent analysis and processing.

It can be understood that the S-CSCF network element can improve the accuracy of the call ticket data by screening that the calling terminal cannot call the target call ticket data of the called terminal through the virtual private network platform and recording, thereby improving the rationality of charging of the operators.

In some embodiments, under the condition that the calling terminal does not call the called terminal through the virtual private network platform, the S-CSCF network element does not trigger the virtual private network platform, sends a call request to the ENS network element for route inquiry and matching with the next hop route, then the ENS sends the call request to the first IBCF network element, the first IBCF network element calls to the second IBCF network element, the second IBCF network element calls to the IMS network, and finally the called terminal is called through the IMS network.

In some embodiments, after determining that the calling terminal calls the called terminal through the virtual private network platform, after the S-CSCF network element triggers the virtual private network platform, if the number information included in the call request is a short number, the S-CSCF network element needs to send the call request to the virtual private network platform first so that the virtual private network platform converts the short number into a trombone, then the call request carrying the trombone is returned to the S-CSCF network element, the S-CSCF network element sends the call request to the ENS network element to perform route query and match with the next hop route, then the ENS sends the call request to the first IBCF network element, the first IBCF network element calls to the second IBCF network element, the second IBCF network element calls to the IMS network, and finally the IMS network calls to the called terminal.

In general, the technical scheme provided by the application can ensure that the virtual private network service is flexibly triggered, and can screen and filter the call request which does not meet the condition of triggering the virtual private network service and record the target call ticket data generated based on the call request, thereby effectively reducing the potential privacy leakage wind direction and improving the network security on one hand; on the other hand, the accuracy of the ticket can be improved, so that the reasonability of charging of operators is enhanced.
