The "New Infrastructure" China Satellite Internet Industry Development Research White Paper points out that more than 70% of the geographical space on Earth, involving 3 billion people, has not achieved Internet coverage. Building a satellite Internet is an important means to solve the digital divide of "Internet-less" population on Earth, and is an effective supplement to achieve network information regional continuous coverage and shared equity.

[0026] In order to enable persons skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by persons skilled in the art without creative work should fall within the scope of protection of the present application.

[0027] It should be noted that the terms "first", "second", and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or a chronological sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to the process, method, product or device.

[0028] According to an embodiment of the present application, a method embodiment of a data processing method is provided. It should be noted that the steps shown in the flowchart of the drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described herein can be executed in an order different from that shown herein.

[0029] Figure 1 is a flowchart of a data processing method according to an embodiment of the present application, as shown in Figure 1 the method comprises the following steps:

[0030] Step S101, determining a plurality of first time instants at which the user equipment accesses the core network through the base station, and determining the first position information of the user equipment at each first time instant, to obtain a plurality of first position information.

[0031] The core network includes a 4G core network and a 5G core network.

[0032] In the 5G network, the access time can be determined by the following method: in the process of successfully attaching to the 5G network, the UE will exchange a series of signaling with the network. For example, in the initial access stage, after the UE completes the random access process, it will establish an RRC connection with the gNodeB (5G base station) and send an RRCSetupRequest message through the connection. The gNodeB responds to the RRCSetup message, and finally the UE sends an RRCSetupComplete message to complete the RRC connection establishment. The time point of these signaling exchanges can be used as a reference for the UE access time. Further, the location information can be determined by the following method: the 5G network location service provides a variety of positioning technologies, including triangle-based positioning technology, scene analysis-based positioning technology, and proximity-based positioning technology. From Rel-16 version, 5G location service has been able to support commercial scenarios and introduced location service capability opening, support for non-3GPP access technology terminal positioning, user positioning privacy protection and other features.

[0033] In the 4G network, the access time can be determined by the following method: when the UE attaches to the 4G network, it will initiate an Attach Request, which will be sent to the Mobility Management Entity (MME) of the 4G core network through the eNodeB (4G base station). The MME will record the access time of the UE when processing the Attach Request, and will feed back relevant information such as the allocated temporary identity and tracking area (TA) information to the UE after successful attachment. Further, the location information can be determined by the following method: the 4G LTE network uses tracking areas to manage the location information of the UE. A TA is composed of multiple cells, and when the UE moves to a new TA, a Tracking Area Update (TAU) process will be triggered. In the TAU process, the UE will report the new Tracking Area Identity (TAI) to the network, and the core network will update the location information of the UE accordingly.

[0034] Step S102, according to the plurality of first time points and the plurality of first location information, determining a first association relationship between the first time point and the first location information.

[0035] The first association relationship is, for example, a function, that is, a functional relationship between the first time point and the first location information is established.

[0036] Step S103, obtaining first access information of the user equipment accessing the core network through the satellite terminal equipment, wherein the first access information at least includes: a first target time.

[0037] It can be understood that when the user equipment uses the VoWiFi service, the user equipment accesses the core network through the satellite terminal equipment, wherein the VoWiFi service allows the user to make voice and video calls in a Wi-Fi environment.

[0038] In step S104, the first target position information is determined according to the first target time and the first correlation.

[0039] For example, the first target time is brought into the first correlation in step S102, and the first target position information corresponding to the first target time is obtained.

[0040] It can be understood that since the position information of the user equipment cannot be directly determined when the user equipment accesses the core network through the satellite terminal equipment, the first correlation established in step S102 can be combined with the time (the first target time) at which the user equipment currently accesses the core network, so as to obtain the position (the first target position information) of the user equipment.

[0041] In step S105, the second target position information of the satellite terminal equipment at the first target time is obtained in the satellite terminal system.

[0042] The satellite terminal system is a key component for realizing satellite-ground integration communication, which can establish a connection with the ground core network through a satellite to provide seamless coverage and communication services for users.

[0043] For example, using the IP address and / or port information of the satellite terminal equipment, the second target position information of the satellite terminal equipment can be searched in a data table in the satellite terminal system, and the data table is as follows.

[0044]

[0045]

[0046] In step S106, if the difference between the first target position information and the second target position information is within a preset interval, a target instruction indicating that the core network and the user equipment perform data interaction is sent to the core network.

[0047] Preferably, the first target position information comprises first target longitude information and first target latitude information, and the second target position information comprises second target longitude information and second target latitude information. Further, the step S106 can be implemented by the following method: determining a first difference value between the first target longitude information and the second target longitude information, and determining a second difference value between the first target latitude information and the second target latitude information; if the first difference value belongs to a first preset range and the second difference value belongs to a second preset range, sending a first instruction to the core network, wherein the first instruction is used to instruct the core network to interact with the user equipment for data; if the first difference value does not belong to the first preset range and / or the second difference value does not belong to the second preset range, sending a second instruction to the core network, wherein the second instruction is used to instruct the core network to refuse to interact with the user equipment for data.

[0048] That is, if the difference value between the first target position information and the second target position information is within the preset interval, the satellite VoWiFi service of the UE is allowed; if the difference value between the first target position information and the second target position information is not within the preset interval, the satellite VoWiFi service of the UE is blocked.

[0049] Through the above steps, a method for allowing or blocking the satellite VoWiFi service in an electronic fence scenario is proposed, so as to limit the use of the satellite VoWiFi service in a specific area, thereby avoiding information leakage or illegal communication in a sensitive area or a confidential occasion. The allowing or blocking of the VoWiFi service can prevent service abuse and ensure service quality, especially in a user-intensive area, network congestion can be avoided, and the stability and reliability of communication can be ensured. In addition, the present application can also ensure that network resources are reasonably allocated, and the VoWiFi service is opened only in an area where service is needed, which helps to improve network efficiency and user experience.

[0050] The steps shown in FIG. 8 are exemplarily described and explained as follows. Figure 1

[0051] According to some optional embodiments of the present application, the first access information further comprises an IP address and / or port information of the satellite terminal device.

[0052] It can be understood that when the user equipment uses VoWiFi, it accesses the 4G or 5G core network through an evolved packet data gateway (ePDG), and the user equipment reports the IP address and / or port number of the access WiFi gateway to the 4G or 5G core network. When the user equipment dials voice service through the satellite network, the IP address and / or port information of the satellite terminal device needs to be reported, and the first access information is as follows.

[0053] ​Further, if the second target position information of the satellite terminal device at the first target time cannot be obtained in the satellite terminal system, the second target position information is determined by the following method: searching for the target satellite terminal device corresponding to the IP address and / or port information in the first access information in the satellite terminal system; determining a plurality of second times at which the target satellite terminal device accesses the core network, and determining second position information of the target satellite terminal device at each second time to obtain a plurality of second position information; determining a second correlation between the second time and the second position information according to the plurality of second times and the plurality of second position information; and determining the second target position information according to the first target time and the second correlation.

[0054] The second correlation is, for example, a function between the second time and the second position information. If the second target position information of the satellite terminal device at the first target time cannot be obtained in the satellite terminal system, the function relationship is established, and the position of the satellite terminal device (the second target position information) can be obtained according to the time at which the user equipment accesses the core network (the first target time).

[0055] According to some optional embodiments of the present application, the first correlation between the first time and the first position information is determined according to the plurality of first times and the plurality of first position information by the following method.

[0056] In the case where the number of first times is 2, the first correlation is determined by the following method: obtaining a first preset function, wherein the first preset function includes a first dependent variable, a first independent variable, a first parameter, and a second parameter, the first dependent variable is the first longitude information in the first position information, and the first independent variable is the first time; obtaining a second preset function, wherein the second preset function includes a second dependent variable, a second independent variable, a third parameter, and a fourth parameter, the second dependent variable is the first latitude information in the first position information, and the second independent variable is the first time; bringing the plurality of first times and the plurality of first longitude information into the first preset function to determine the values of the first parameter and the second parameter to obtain a first target function between the first time and the first longitude information; and bringing the plurality of first times and the plurality of first latitude information into the second preset function to determine the values of the third parameter and the fourth parameter to obtain a second target function between the first time and the first latitude information.

[0057] For example, the first preset function is represented by the following form:

[0058] X n = i + kt n

[0059] wherein X n is the first longitude information, and t nis a first time, i is a first parameter, and k is a second parameter.

[0060] The second preset function is expressed in the following form:

[0061] Y n = m + lt n

[0062] where Y n is first latitude information, m is a third parameter, and l is a fourth parameter.

[0063] Example IP address Port number User equipment B 7.0.0.1 8080

[0064] The values of i and k can be obtained by bringing the two first times and the two first longitude information into the first preset function, and the values of m and l can be obtained by bringing the two first times and the two first latitude information into the second preset function.

[0065] On the other hand, in the case where the number of first times is greater than 2, the first correlation can be determined by the following method: obtaining a first preset multiple linear regression function, wherein the first preset multiple linear regression function includes a third dependent variable, a plurality of third independent variables, and a plurality of fifth parameters, the third dependent variable is the first longitude information in the first position information, and the plurality of third independent variables are the plurality of first times; obtaining a second preset multiple linear regression function, wherein the second preset multiple linear regression function includes a fourth dependent variable, a plurality of fourth independent variables, and a plurality of sixth parameters, the fourth dependent variable is the first latitude information in the first position information, and the plurality of fourth independent variables are the plurality of first times; bringing the plurality of first times and the plurality of first longitude information into the first preset multiple linear regression function, and determining the values of the plurality of fifth parameters by using the least square method to obtain a third objective function between the first times and the first longitude information; and bringing the plurality of first times and the plurality of first latitude information into the second preset multiple linear regression function, and determining the values of the plurality of sixth parameters by using the least square method to obtain a fourth objective function between the first times and the first latitude information.

[0066] For example, the third preset function can be expressed in the following form:

[0067] y1 = a0 + a1x1 + a2x2 + … + a n-1 x n-1 + Δ1

[0068] where y1 is the first longitude information, x1 to x n-1 are the plurality of first times, a0 to a n-1 are the fifth parameters, and Δ1 is the accidental error.

[0069] The fourth preset function can be expressed in the following form:

[0070] y2 = b0 + b1x1 + b2x2 +... + b n-1 x n-1 + Δ2

[0071] wherein y2 is the first latitude information, b0 to b n-1 is the sixth parameter, and Δ2 is the accidental error.

[0072] In the case where the number of the first time instants is m (m is greater than 2), the m first time instants and the m first longitude information within the first preset historical time length are brought into a third preset function, and a multivariate linear regression function is solved by the least square method, so that the values of a0 to a n-1 are obtained. The m first time instants and the m first latitude information are brought into a fourth preset function, and a multivariate linear regression function is solved by the least square method, so that the values of b0 to b n-1 are obtained.

[0073] In some optional embodiments of the present application, if the difference between the first target position information and the second target position information is within a preset interval, a target instruction indicating that the core network and the user equipment perform data interaction is sent to the core network, which can be implemented by the following method. In the case where the number of the first time instants is 2, the difference between the two first time instants is determined, and in the case where the difference between the two first time instants is greater than a preset threshold, the following steps can be performed: obtaining authentication information of the user equipment when the user equipment accesses the core network through the satellite terminal equipment for the first time, wherein the authentication information includes: a user equipment identifier; searching for a first credit score corresponding to the user equipment identifier in a network management system, and if the difference between the first target position information and the second target position information is within a preset interval and the first credit score is greater than a first preset score, sending the target instruction to the core network; or obtaining a historical time length, a historical data transmission amount and a historical interaction frequency of the user equipment in data interaction with the core network through the satellite terminal equipment; determining a second credit score corresponding to the user equipment according to the historical time length, the historical data transmission amount and the historical interaction frequency; and if the difference between the first target position information and the second target position information is within a preset interval and the second credit score is greater than a second preset score, sending the target instruction to the core network.

[0074] It is worth noting that in the case of the number of the first time points being 2, if the interval between the two first time points is large, the authenticity of the first association relationship between the first time point and the first location information is weak. Based on this, the embodiment finds the first credit score corresponding to the user equipment identifier in the network management system in the case that the interval between the two first time points is large, and if the difference between the first target location information and the second target location information is within the preset interval and the user equipment is known to be a good credit user according to the first credit score, the satellite VoWiFi service of the UE is put through. If the difference between the first target location information and the second target location information is within the preset interval and the user equipment is known to be a poor credit user according to the first credit score, the satellite VoWiFi service of the UE is temporarily blocked this time.

[0075] On the other hand, the historical duration a, the historical data transmission amount b and the historical interaction frequency c of the UE in data interaction with the core network through the satellite terminal device can also be obtained, and the second credit score corresponding to the UE is determined according to the weight w1 corresponding to a, the weight w2 corresponding to b and the weight w3 corresponding to c. If the difference between the first target location information and the second target location information is within the preset interval and the second credit score is high, it means that the user equipment is a good credit user, and a target instruction is sent to the core network to put through the satellite VoWiFi service of the UE.

[0076] Preferably, the first access information of the user equipment accessing the core network through the satellite terminal device is obtained, which can be achieved by the following method: obtaining the first access information of the user equipment currently connected to the ePDG through the satellite terminal device and accessing the core network through the ePDG. It can be understood that according to the 3GPP protocol, when the user equipment uses VoWiFi, it accesses the 4G or 5G core network through the ePDG.

[0077] According to the above steps, a plurality of first time instants at which the user equipment accesses the core network through the base station is determined, and a plurality of first position information of the user equipment at each first time instant is determined to obtain the plurality of first position information; a first association relationship between the first time instant and the first position information is determined according to the plurality of first time instants and the plurality of first position information; first access information of the user equipment accessing the core network through the satellite terminal equipment is obtained, wherein the first access information at least includes: a first target time instant; a first target position information is determined according to the first target time instant and the first association relationship; a second target position information of the satellite terminal equipment at the first target time instant is obtained in the satellite terminal system; if the difference between the first target position information and the second target position information is within a preset interval, a target instruction indicating that the core network and the user equipment perform data interaction is sent to the core network, which achieves the purpose of positioning the user equipment when the user equipment accesses the core network through the satellite terminal equipment, thereby realizing the technical effect of managing the interaction data between the core network and the user equipment based on the position information of the user equipment.

[0078] Figure 2 is a flowchart of another data processing method according to an embodiment of the application. The method uses satellite terminal position and combines recent cell access information of the mobile phone to match the user position, and can establish a position model according to multiple cell access position information for simulation. At the same time, the position of the mobile terminal accessing the mobile network is calculated to determine the position of the mobile phone when making a call. The mobile phone and the satellite terminal are associated through the IP address and port number of the satellite terminal, and the latitude and longitude of the two are matched. The effect is to determine whether to enable satellite VoWiFi service, mainly applied to electronic fence scenarios. Figure 3 is a schematic diagram of a data processing system according to an embodiment of the application. The following will be described in detail Figure 2 and Figure 3 how to determine the position of the mobile phone.

[0079] Step S201, satellite terminal data reporting. In the existing network, the satellite terminal reports its longitude and latitude to the satellite terminal system in real time. It can be understood that, in order to ensure that the network address does not conflict, the IP address and port number of the satellite terminal are allocated according to rules, and can be queried in the satellite terminal system, as shown in Table 2-1.

[0080]

[0081] Table 2-1

[0082] According to the 3GPP protocol, when a user uses VoWiFi, the terminal accesses the core network (5GC / EPC, 5GC is a 5G core network, and EPC is a 4G core network) through an ePDG, and the terminal reports the IP address and port number of the access WiFi gateway to the network. In the scenario of integrated networking of space and ground, the terminal reports the IP address and port number of the satellite terminal to the network, as shown in Table 2-2.

[0083] Example IP address Port number Access time Mobile B 7.0.0.1 8080 6 / 1 8：30

[0084] Table 2-2

[0085] According to the satellite terminal access time point, the extraction processing is performed, as shown in Table 2-3.

[0086] Time Cell ID Longitude Latitude Mobile B 6 / 1 8：00 10 E20°25′ N30°50′ Mobile B 6 / 1 8：55 11 E21°05′ N30°30′

[0087] Table 2-3

[0088] Step S202, the function of the mobile phone position and time is calculated.

[0089] It can be understood that the mobile phone can be moving, and therefore the access condition in a period of time is selected to calculate the user position, as follows:

[0090] X n = i + kt n

[0091] Y n = m + lt n

[0092] Wherein, (X0, Y0, t0) represents the time of the last access of the mobile terminal to the network, (X0, Y0) represents the longitude and latitude of the last access of the mobile terminal to the network; (X1, Y1, t1) represents the time of the next access of the mobile terminal to the network, (X1, Y1) represents the longitude and latitude of the next access of the mobile terminal to the network. Substituting (X0, Y0, t0) and (X1, Y1, t1) can obtain the values of i, k, m, and l.

[0093] Substituting the call time of the mobile phone, the longitude and latitude (X VoWiFi , Y VoWiFi , t VoWiFi ) of the VoWiFi call time of the mobile phone can be obtained. As shown in Table 2-4.

[0094]

[0095] Table 2-4

[0096] Step S203, the satellite terminal position is calculated.

[0097] If the satellite terminal reports its longitude and latitude in real time, the values are directly taken, as shown in Table 2-5.

[0098] Example IP address Port number Access time Longitude Latitude Satellite terminal A 7.0.0.1 8080 6 / 1 8：30 E 21°12′ N30°50′

[0099] Table 2-5

[0100] If the longitude and latitude cannot be obtained in real time, since the equipment (ship, airplane, etc.) on which the satellite terminal is installed can be moving, the access condition in a period of time is selected to calculate the user's location, as follows:

[0101] X n = a + bt n

[0102] Y n = c + dt n

[0103] Wherein, (X0, Y0, t0) represents the time when the satellite terminal accesses the network last time, (X0, Y0) represents the longitude and latitude when the satellite terminal accesses the network last time; (X1, Y1, t1) represents the time when the satellite terminal accesses the network next time, (X1, Y1) represents the longitude and latitude when the satellite terminal accesses the network next time. Substituting (X0, Y0, t0) and (X1, Y1, t1) can obtain the values of a, b, c and d.

[0104] Substituting the data in Table 2-1, the longitude and latitude of the satellite terminal when the mobile phone accesses can be obtained, as shown in Table 2-6.

[0105]

[0106] Table 2-6

[0107] Step S204, location tracing.

[0108] When the user dials the VoWiFi service of the integrated satellite-terrestrial networking, the satellite terminal reports the longitude and latitude of the current access according to the service flow. Meanwhile, the IP address and port number of the current access terminal are stored in the satellite terminal system. If the satellite terminal does not report the longitude and latitude, the longitude and latitude of the satellite terminal at the current access time are calculated according to the longitude and latitude of the satellite terminal accessed last time and next time. On the other hand, the mobile phone terminal accesses the mobile network and reports the current access base station information. According to the last time and next time access base station information, the call time and the longitude and latitude of the mobile phone can be calculated.

[0109] Since the mobile terminal needs to report the IP address and port number of the access gateway, i.e. the IP address and port number of the satellite terminal, when dialing voice service through the satellite network, the two pieces of information can be matched. By comparing and measuring the latitude and longitude of the satellite terminal and the mobile phone, the user location can be traced, and it can be determined whether the user is passing through. If the difference exceeds the error range, the user is not allowed to pass through.

[0110] Alternatively, in practice, the relationship between variables is not always linear. In this embodiment, the independent variable is time, and the dependent variable is longitude and latitude. A multiple linear regression model is used for analysis and prediction. The multiple linear regression model is as follows:

[0111] y=a0+a1x1+a2x2+…+a n-1 x n-1 +Δ

[0112] In the formula, x1, x2, …, x n-1 are independent variables, y is the dependent variable, a1, a2, …, a n-1 are regression parameters to be solved, and Δ is random error. These parameters can be solved by the least squares method.

[0113] The information obtained in steps S202 and S203 is substituted into the model to establish the model, as shown in Table 2-7:

[0114]

[0115]

[0116] Table 2-7

[0117] Further, according to the established model, the access time is input to obtain the user location information and determine whether the location is allowed to pass through.
