For a clearer understanding of the present application, the entire flow of the terminal identification method will be described below.
As shown in fig. 3, the flow of the method provided by this embodiment includes the following steps.
S301, judging whether the terminal equipment supports the VoLTE service on hardware or not, and if so, continuing to execute the step S302; and if the judgment result is negative, the terminal equipment is not processed.
Specifically, the model approval number is the first six digits of the international mobile equipment identity code, generally represents the model, each terminal corresponds to a unique IMEI, and according to the IMEI of the terminal, the brand and model of the terminal can be known, and whether the terminal supports VoLTE service or not can be known. The terminal identification library comprises model approval numbers of all terminal equipment supporting VoLTE service on hardware, and the model approval number of the terminal equipment currently logging in the 4G network is obtained; and judging whether the model approval number exists in the terminal identification library, if so, indicating that the terminal equipment corresponding to the model approval number is a target terminal supporting the VoLTE service on hardware.
S302, judging whether the adhesion ticket information generated by the target terminal in the adhesion flow, the connection information in the PDN connection flow and the SIP ticket information in the IMS registration flow meet preset conditions, if so, executing the step S303.
Specifically, session Initiation Protocol (SIP) interface signaling data and S1 control plane (S1-MME) interface signaling data are collected, that is, the attachment ticket information generated by the target terminal in the attachment flow and the connection information in the Packet Data Network (PDN) connection flow are collected through the S1-MME interface; and collecting SIP call ticket information through the SIP interface.
Further, a first field, a second field and a third field are respectively extracted from the attach ticket information, wherein the first field is a field indicating that the target terminal supports the VoLTE service capability and the voice service priority, the second field is used for indicating whether the network of the target terminal supports the VoLTE service and whether the target terminal has signed up for the VoLTE service, and the third field is used for indicating whether the target terminal supports the voice fallback to a 2G or 3G network in a call state.
Wherein the preset conditions include: the value of the first field indicates that the target terminal supports the VoLTE service and the priority of the voice service is higher; the value of the second field indicates that the network of the target terminal supports VoLTE service and the target terminal has signed up for the VoLTE service; the value of the third field indicates that the target terminal supports voice fallback to a 2G or 3G network in a call state; the connection information in the PDN connection flow does not contain IP multimedia subsystem IMS information; and the registration information is not recorded in the SIP call ticket.
Specifically, based on the interface signaling data of the target terminal, the VoLTE capability of the target terminal and the voice service priority are analyzed and judged (i.e. the first field vdp _ uus field), and a record that the terminal supports the VoLTE service and has voice priority in the Attach ticket is found. Then, a field (i.e. the first field in this embodiment) indicating the VoLTE capability of the target terminal and the priority of the voice service is first located in the attached ticket information, and if the target value of the first field indicates that the terminal supports VoLTE and the voice priority is higher, the next field is determined. The next field is the second field imsvops field, and the analysis and judgment (that is, the second field imsvops field) is performed based on the 1 st bit (lowest bit) of the first byte (highest byte) of the Attach call ticket information EMS _ NFS, so as to find the record that the network supports VoLTE and the user has signed the VoLTE subscription. And then, based on S1-MME signaling data, finding a field for judging whether the voice falls back to the 2G/3G network in the terminal attachment flow information, namely a third field srvcc field, and further judging the VoLTE support capability of the target terminal according to the third field. And finally, based on whether the VoLTE information is used in the terminal signaling or not, finding out that the registration information such as Register, calling, re-Register and the like does not exist in the Procedure Type of the Procedure Type in the SIP protocol ticket without containing IMS/IMS information in the connection information in the PDN connection flow.
In a possible case of this embodiment, the first field is a vdp _ uus field, the second field is an imsvops field, and the third field is an srvcc field, where if the value of the first field is "03", it indicates that the target terminal supports the VoLTE service and the priority of the voice service is higher; if the value of the second field is '1', the network of the target terminal supports the VoLTE service and the target terminal signs the VoLTE service; if the value of the third field is 1, the target terminal supports voice fallback to a 2G or 3G network in the call state. Meanwhile, based on whether the VoLTE information is used in the terminal signaling or not for analysis and judgment, the PDN flow does not contain IMS/IMS information, and the record of Register, calling and Re-Register registration information does not appear in the Procedure Type process Type in the SIP protocol ticket.
S303, judging whether the VoLTE service support index of the target terminal is smaller than a preset threshold value, if so, determining that the target terminal does not support the VoLTE service on hardware support software.
Specifically, according to the identifier of the target terminal, a VoLTE service support index of a Tracking Area (TAC) where the target terminal of the user is located is obtained in a communication system database, the size of the VoLTE service support index of the target terminal and a preset threshold is judged, and if the VoLTE service support index of the target terminal is smaller than the preset threshold on the basis that the target terminal meets the preset condition, it is determined that the VoLTE service is not supported on hardware and software of the target terminal.
The VoLTE service support index is a ratio of terminals supporting VoLTE service to all terminals in a TAC area.
The preset threshold may be set according to an actual situation, for example, set to 30%, and when the VoLTE service support index of the target terminal is less than 30%, it indicates that the target terminal does not support the VoLTE service on software.
In the embodiment, the condition that the terminal can support the volt capability is analyzed in real time from call ticket flows of terminal user signaling information, PDN connection, attachment and the like based on SIP interface signaling and S1-MME interface signaling data of the terminal, so that the terminal which is not supported by hardware support software is dynamically identified, and the identification efficiency and accuracy are improved.
In a possible embodiment, if the preset conditions are met within a cumulative number of days (for example, 3 days or 5 days) of the same target terminal, and the VoLTE service support index of the TAC region where the target terminal of the user is located is smaller than the preset threshold, it is determined that the terminal does not support the VoLTE service on hardware and software.
In the embodiment, the signaling information of the target terminal is analyzed by accumulating multiple days, the VoLTE service support index in the TAC area is determined, and the accuracy of terminal identification is further improved.
