[0051] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0052] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0053] The terms "preset", "first", "second", "third", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in sequences other than those illustrated or described herein, for example.

[0054] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0055] With the development of wireless communication technology and the introduction of frequency reduction and network withdrawal policies, more and more terminal users rely on the wireless voice call function provided by VoLTE technology. VoLTE has many advantages, such as shorter connection waiting time, higher quality and more natural voice and video call effects. Compared with traditional 2G / 3G voice solutions, the advantages of VoLTE high-definition voice calls are mainly reflected in shorter waiting time for connection, no need for terminals to fall back from 4G network to 2G / 3G network during calls, clearer and more natural call quality, and high-speed Internet access during calls.

[0056] Terminal devices on the market have different functions. In order to clarify whether a terminal supports the VoLTE function, the existing technology mainly determines it based on official information provided by the terminal device manufacturer and firmware version upgrade information.

[0057] However, the above official information and firmware version upgrade information are greatly affected by the subjective behavior of equipment manufacturers, and the accuracy and completeness of the data cannot be guaranteed, resulting in the inability to accurately identify the VoLTE support capabilities of user terminals.

[0058] In response to the above problems, this application provides a terminal VoLTE function identification method, which mainly stores all model approval numbers that support the VoLTE function in hardware in advance according to the terminal type classification in the dynamic terminal library. When identifying the terminal, directly obtain its model approval number and find the corresponding terminal type in the dynamic terminal library. When the terminal type corresponding to the model approval number is found, it means that the terminal to be identified supports the VoLTE function in hardware. If the terminal type is a 5G terminal, it is directly determined that the terminal to be identified also supports the VoLTE function in software; if the terminal type is a 4G terminal, it is necessary to further determine whether the terminal software supports the VoLTE function based on the S1 interface signaling data of the terminal to be identified.

[0059] The following specific embodiments are used to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above technical problems. The following specific embodiments can be implemented independently or in combination with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0060] Figure 1 This is a schematic diagram of an application scenario provided by an embodiment of the present application. In actual application, the terminal user needs to turn on the VoLTE switch of the terminal to enjoy the relevant functional services. Figure 1 As shown, the embodiment of the present invention can be applied to a mobile phone terminal, and the mobile phone user can freely turn on or off the VoLTE function.

[0061] In a possible implementation, in the first step, the mobile phone user searches for the "settings" application software on the mobile phone desktop, clicks the button, and enters the second step page, that is, Figure 1 The page shown in the left picture, find "Network Data Options" on this page, click to enter the third step page, that is Figure 1 The page shown in the middle picture, click the "Voice and Data" option on this page, and click to enter the fourth step page, that is Figure 1 The page shown in the right picture shows the "VoLTE" item and its corresponding right button on this page. In the right picture, the right button is turned on, so Figure 1 All the images in the video have an "HD" logo in the upper left corner. If the user wants to turn off the VoLTE function, just click the button on the right side of the "VoLTE" item to turn it off. Figure 1 The "HD" logo in the upper left corner of all images will disappear.

[0062] By finding the button corresponding to the "VoLTE" item on the terminal, you can turn on the VoLTE function, which can not only improve the user's call quality, but also effectively increase the VoLTE penetration rate.

[0063] Combine the following Figure 2 The specific embodiments illustrate the implementation process of determining the terminal type and then identifying the VoLTE function according to the model approval number of the terminal to be identified in the terminal VoLTE function identification method of the present application.

[0064] Figure 2 A process for identifying a terminal VoLTE function provided in an embodiment of the present application Figure 1 .like Figure 2 As shown, the method includes:

[0065] S201, obtain the model approval number of the terminal to be identified, and obtain the terminal type corresponding to the model approval number from the dynamic terminal library, wherein the terminal type is a 4G terminal or a 5G terminal, and the dynamic terminal library stores the model approval number corresponding to each terminal type that supports the VoLTE function in hardware.

[0066] The International Mobile Equipment Identity (IMEI) is commonly referred to as the mobile phone serial number or "serial number" of a mobile phone. It is used to identify each independent mobile phone and other mobile communication devices in the mobile phone network, which is equivalent to the ID card of a mobile phone. The serial number has 15-17 digits. The first 8 digits (Type Allocation Code, TAC) are the model approval number (6 digits in the early days), which is the code to distinguish the brand and model of the mobile phone; the next 2 digits (Final Assembly Code, FAC) are the final assembly number (only exists in early models), representing the final assembly site code; the last 6 digits (Final Assembly Code, SNR) are the serial number, representing the production sequence number. The International Mobile Equipment Identity is generally affixed to the back of the phone and the outer packaging, and also exists in the phone's memory.

[0067] In this step, the dynamic terminal library includes the model approval numbers of 4G terminals and 5G terminals that support the VoLTE function in hardware. When the VoLTE function of the terminal needs to be identified, it is only necessary to search the model approval number of the terminal to be identified in the dynamic terminal library. If the model approval number is found, it can be directly determined that the terminal to be identified is a terminal that supports the VoLTE function in hardware. As for whether the VoLTE function is also supported in software, it needs to be further determined based on the terminal type.

[0068] S202: If the terminal type of the terminal to be identified is a 5G terminal, identify the terminal to be identified as a terminal that supports the VoLTE function in both software and hardware.

[0069] In the above scheme, with the advent of the 5G era, the VoLTE function has become a basic functional service of 5G terminals. Therefore, as long as it is determined that the terminal to be identified is a 5G terminal, there is no doubt that the terminal to be identified supports the VoLTE function in both software and hardware.

[0070] S203: If the terminal type of the terminal to be identified is a 4G terminal, S1 interface signaling data of the terminal to be identified is obtained, where the S1 interface signaling data is S1-MME interface signaling data or S1-U interface signaling data.

[0071] In this step, after determining that the terminal to be identified is a 4G terminal, it is also necessary to further determine whether the terminal also supports the VoLTE function in software in combination with the S1 interface signaling data. It is well known to those skilled in the art that the S1 interface is an interface between the wireless network and the core network, which includes two interfaces:

[0072] S1-U: User plane, used to connect eNB and SGW for transmitting service data;

[0073] S1-MME: control plane, used to connect eNB and MME for signaling.

[0074] Therefore, the S1 interface signaling data of the terminal to be identified includes two types of S1-MME interface signaling data and S1-U interface signaling data. In the embodiment of the present application, different S1 interface signaling data acquisition methods are set for different types of S1 interfaces, as well as different judgment methods for whether the corresponding software supports the VoLTE function in the subsequent process.

[0075] When S1-MME interface signaling data is used as S1 interface signaling data, the data acquisition method is: based on the S1-MME interface, obtain the attachment call record information generated by the terminal to be identified in the attachment process; obtain the voice service field, subscription field and multimedia field in the attachment call record information, wherein the voice service field is used to indicate that the terminal to be identified supports the VoLTE function and the voice service priority field, and the subscription field is used to indicate whether the network of the terminal to be identified supports the VoLTE function and whether the terminal to be identified has subscribed to the VoLTE function; the multimedia field is used to indicate whether the terminal to be identified is registered with the IP multimedia subsystem; the voice service field, subscription field and multimedia field are used as the S1 interface signaling data of the terminal to be identified.

[0076] There are multiple fields in the attachment call record information generated by the terminal to be identified in the attachment process, and different fields represent different meanings, such as TACid: terminal brand and model; VDP_UUS: terminal supports VoLTE capability and voice priority, which is the voice service field in this application; IMS VoPS: network Volte capability and contract indication, which is the contract field in this application; SRVCC: terminal supports VoLTE to 2G / 3G voice continuity capability; APN_REQ: when the terminal registers to IMS, it contains its access point name, which is the multimedia field in this application; APN: when the network allocates a bearer, it will contain the IMS URL; Bear_status: when the tracking area is updated, it contains the ims default bearer status indication.

[0077] When S1-U interface signaling data is used as S1 interface signaling data, the data acquisition method is: based on the S1-U interface, the firmware version number of the terminal to be identified is obtained, and the firmware version number is used as the S1 interface signaling data of the terminal to be identified.

[0078] There is also a data-level reason for setting corresponding data acquisition methods for different types of S1 interfaces, as follows: the attachment bill information generated by the terminal to be identified during the attachment process may not include the voice service field, contract field and multimedia field, or the values ​​of these fields may be wrong. In this case, it is necessary to obtain the correct S1 interface signaling data based on the S1-U interface; the firmware version number reported by the terminal to be identified may also be wrong. In this case, it is necessary to obtain the correct S1 interface signaling data based on the S1-MME interface.

[0079] S204: Based on the S1 interface signaling data, identify whether the terminal to be identified supports the VoLTE function in software.

[0080] In the above scheme, when the S1 interface signaling data is S1-MME interface signaling data, as long as the following conditions are met at the same time, it can be identified that the terminal to be identified supports the VoLTE function in software. These conditions are: the value of the voice service field indicates that the terminal to be identified supports the VoLTE function and the voice service has a higher priority than other services; the value of the subscription field indicates that the network of the terminal to be identified supports the VoLTE function and the terminal to be identified has signed a contract for the VoLTE function; the value of the multimedia field indicates that the terminal to be identified has registered the IP multimedia subsystem and the access point name of the IP multimedia subsystem registered by the terminal to be identified.

[0081] In the specific implementation process, the voice service field VDP_UUS has four value ranges: 0x01-0x03 represents that the terminal supports Volte and voice is prioritized; 0x05-0x07 represents that Volte is supported and data is prioritized; 0x00 and 0x04 both represent that VoLTE is not supported. For example, if the value of the voice service field of the terminal to be identified is 0x02 in the attached call record, it means that the terminal to be identified supports the VoLTE function and the voice service has a higher priority than other services. The terminal to be identified may support the VoLTE function in software; if the value of the voice service field is 0x07, it means that the terminal to be identified supports the VoLTE function but other services have a higher priority than voice services. At this time, it is determined that the terminal to be identified does not support the VoLTE function in software.

[0082] When the S1 interface signaling data is S1-U interface signaling data, further judgment is required based on the model approval number and firmware version number of the terminal to be identified. First, based on the model approval number and firmware version number of the terminal to be identified, it is judged whether the firmware version number of the terminal to be identified exists in the dynamic software library. The dynamic software library stores the firmware version number that supports the VoLTE function in software corresponding to each model approval number; if the firmware version number of the terminal to be identified exists, it is identified that the terminal to be identified supports the VoLTE function in software; if the firmware version number of the terminal to be identified does not exist, it is identified that the terminal to be identified does not support the VoLTE function in software.

[0083] The terminal VoLTE function identification method provided in this embodiment obtains the model approval number of the terminal to be identified so as to find the terminal type to which it belongs in the dynamic terminal library. When the terminal type corresponding to the model approval number is found, it indicates that the terminal to be identified supports the VoLTE function in hardware. If the terminal type is a 5G terminal, it is directly determined that the terminal to be identified also supports the VoLTE function in software; if the terminal type is a 4G terminal, it is necessary to further determine whether the terminal software supports the VoLTE function based on the S1 interface signaling data of the terminal to be identified.

[0084] Combine the following Figure 3 The specific embodiments illustrate the implementation process of identifying whether the VoLTE function is enabled in the terminal to be identified according to the SIP interface signaling data in the terminal VoLTE function identification method of the present application.

[0085] Figure 3 A process for identifying a terminal VoLTE function provided in an embodiment of the present application Figure 2 .like Figure 3 As shown, the method includes:

[0086] S301: Acquire Session Initiation Protocol (SIP) interface signaling data of a terminal to be identified.

[0087] S302: Based on the SIP interface signaling data, obtain SIP call list information of the terminal to be identified.

[0088] In the above scheme, the Session Initialization Protocol (SIP) is a multimedia communication protocol and an IP voice session control protocol originating from the Internet. It is flexible, easy to implement, and easy to expand. The basic functions of SIP are to locate a terminal, generate communication requests, establish sessions, and end sessions. Based on the SIP interface, the SIP interface signaling data generated by the terminal to be identified during the session is obtained, and then the SIP call list information of the terminal to be identified is obtained.

[0089] S303: Determine whether the registration process information is recorded in the SIP call record information.

[0090] In this step, the registration process information can be registration (Register), call (, calling), re-register (, Re-register). If the registration process information is recorded in the Procedure Type process type data in the SIP signaling, it means that the registration process procedure_status is in the switch-on state, that is, the VoLTE function is turned on; if the registration process information is not recorded in the Procedure Type process type data in the SIP signaling, it means that the VoLTE function is turned off.

[0091] S304: If yes, determine that the terminal to be identified has enabled the VoLTE function;

[0092] S305: If not, determine that the terminal to be identified has disabled the VoLTE function.

[0093] In an embodiment of the present application, the Session Initiation Protocol SIP interface signaling data of the terminal to be identified is collected to obtain SIP call list information, and the terminal to be identified is identified based on the registration process information recorded in the SIP call list to enable the VoLTE function.

[0094] In summary of the above embodiments, the terminal VoLTE function identification method provided in the embodiments of the present application first determines the terminal type of the terminal to be identified based on the model approval number of the terminal to be identified and the pre-established dynamic terminal library. After determining the initial terminal type, it can be directly determined that the terminal supports the VoLTE function in hardware, and then further determines whether the VoLTE function is supported in software based on the terminal type. If the terminal to be identified is a 5G terminal, the terminal supports the VoLTE function in software; if the terminal to be identified is a 4G terminal, it is necessary to combine the attached call list information or firmware version number in the S1 interface signaling data to identify whether the terminal software supports the VoLTE function.
