TECHNICAL FIELD

[0002] Currently, ENDC (EUTRA-NR Dual Connectivity) represents new radio-dual connectivity. According to the 3GPP (3rd Generation Partnership Project) standard document, ENDC allows user equipment to be connected to an LTE (Long Term Evolution) enodeB serving as a master node and a 5G gnodeB serving as an auxiliary node. For Sprint, ENDC will allow devices to access LTE and 5G (5th generation mobile networks) on the same frequency band at the same time, therefore, the NSA (Non-standlone) mode based on ENDC not only realizes the LTE network side, but also realizes the 5G network side, thereby realizing a new wireless network.

[0003] However, due to the change of the 5G network architecture, new threats to network security and user privacy have been brought. Due to the current networking requirements, most of the 5G networks are based on the NSA mode of ENDC, which must add an NR (New Radio) cell as a secondary cell, which provides an opportunity for NR pseudo base stations to interfere and attack, thereby threatening network management, and thus passively searching for a pseudo base station when interfered and attacked by the pseudo base station to identify the pseudo base station.

PCI is a key parameter on the LTE air interface, and it affects the distribution of cell reference signals and control signals in the frequency domain. A terminal can learn the PCI of a cell by detecting a synchronization channel. To ensure that a terminal can detect a PCI, the PCI must be unique in adjacent cells.

[0103] Reference Figure 1 , Figure 1The structure diagram of the NSA network-based pseudo base station identification device related to the hardware running environment of the embodiment of the present application is shown.

[0104] As shown in Figure 1 , the NSA network-based pseudo base station identification device can include a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005.

The memory 1005 can be a high-speed random access memory (RAM); it can also be a stable memory, such as a non-volatile memory (Non-volatile Memory), and specifically can be a disk memory. The memory 1005 can also be an independent storage device from the aforementioned processor 1001.

[0105] Those skilled in the art can understand that Figure 1 the structure shown in the above description does not constitute a limitation on the NSA network-based pseudo base station identification device, and can include more or fewer components than the diagram, or combine certain components, or different component arrangements.

[0106] As shown in Figure 1 , the memory 1005 as a computer storage medium can include an operating system, a network communication module, a user interface module, and a NSA network-based pseudo base station identification program.

[0107] In the NSA network-based pseudo base station identification device shown in Figure 1 , the network interface 1004 is mainly used to connect a background server and communicate data with the background server; the user interface 1003 is mainly used to connect an external device; the NSA network-based pseudo base station identification device calls the NSA network-based pseudo base station identification program stored in the memory 1005 through the processor 1001, and executes the NSA network-based pseudo base station identification method provided by the embodiment of the present application.

[0108] Based on the above hardware structure, embodiments of the NSA network-based pseudo base station identification method of the present application are proposed.

[0109] Referring to Figure 2 ,Figure 2 This is a flowchart illustrating the first embodiment of the fake base station identification method based on NSA network of the present invention.

[0110] In the first embodiment, the fake base station identification method based on the NSA network includes the following steps:

[0111] Step S10: Obtain neighboring cell information reported by user equipment in the NSA network.

[0112] It should be noted that the execution subject of this embodiment is a fake base station identification device based on the NSA network. It can also be other devices that can achieve the same or similar functions. This embodiment does not limit this. In this embodiment, the eNB base station is used as the execution subject. In this embodiment, it can also be called the source base station. The eNB base station is a base station located on the LTE side.

[0113] Since this embodiment is based on an NSA network, enabling migration from the eNB side to the gNB side, a connection needs to be established with the gNB side to achieve this migration. Figure 3 The diagram shows a network architecture based on ENDC for NSA. First, the UE accesses normally from the eNB side. Then, a gNB is added as a secondary cell base station, i.e., a neighboring base station. The signaling flow is on the LTE side, and the data flow is on the NR side. The signaling interaction between the base station and the UE is completed by the LTE sending a reconfiguration message. The cell where the eNB is located is the current cell, and the cells adjacent to the current cell are neighboring cells, also known as secondary cells. Since the ANR of the NSA network can detect new neighboring cells, the neighboring cell information reported by the user equipment can be obtained. The neighboring cell information includes B1 measurement information used for ANR, and system information of the target cell such as CGI, PLMN list, TAC, LAC, or RAC. It may also include other parameter information. This embodiment does not limit this. The identification of neighboring cells can be achieved through CGI, which facilitates the analysis of neighboring cells.

[0114] To achieve network migration, such as Figure 4The signaling interaction diagram shows that the UE message is a normal access of a 4G terminal, and a default bearer is established. Next, the RRC Connection Reconfiguration to the measurement report MR is three signaling, and the main purpose is to trigger the gNB addition process. After the measurement report is reported, the gNB addition threshold is met, the addition process is triggered, the eNB sends an SgNB addition request message on the X2 interface, the gNB prepares the related resources, and the eNB replies to the SgNB addition request ACK. The ACK message contains a container, including the configuration of the air interface resource. After the eNB receives the ACK message, the container in the ACK message is sent to the terminal in the form of RRC connection reconfiguration to configure the terminal air interface. After the terminal air interface configuration is completed, the RRC connection reconfiguration complete is replied. After the eNB receives the reconfiguration complete message, the SgNB reconfiguration complete message is replied to the gNB on the X2 interface, which means that the air interface of the gNB is ready. The ERAB modification indication and confirmation are to migrate the S1-U from the eNB side to the gNB side, thereby completing the migration of the silent bearer to the split bearer.

[0115] Step S20: judging whether the local neighbor relation table stores the adjacent cell information.

[0116] It should be noted that the local neighbor relation table is an NRT managed by the ANR. The ANR function resides in the eNB and is responsible for managing the NRT. The neighbor detection function is responsible for discovering new neighbors and adding them to the NRT. The neighbor deletion function is responsible for cleaning up useless neighbors. The LTE system adjacent cell is automatically discovered by the UE measurement, and is no longer completely configured by O&M. The O&M management and configuration work of the eNB neighbor relation is reduced, which is the goal of the SON function.

[0117] In the embodiment, by judging whether the local neighbor relation table stores the adjacent cell information, the unknown adjacent base station in the adjacent cell information can be obtained, so that the unknown adjacent base station can be actively identified as a pseudo base station.

[0118] In a specific implementation, since the adjacent cell information includes the CGI information, i.e., the cell identification code, by judging whether the CGI is stored in the local adjacent cell relationship table, when the CGI is stored, it indicates that the adjacent base station corresponding to the CGI in the adjacent cell information is known, and when the CGI is not stored, it indicates that the adjacent base station corresponding to the CGI in the adjacent cell information is unknown, i.e., a new adjacent base station appears, in this case, it is necessary to establish a connection with the new adjacent base station, so as to realize the active pseudo base station search.

[0119] Step S30: When the adjacent cell information is not stored in the adjacent cell relationship table, performing network switching on the adjacent base station corresponding to the adjacent cell information to obtain a network switching result.

[0120] It can be understood that when the adjacent cell information is not stored in the adjacent cell relationship table, it indicates that the adjacent base station corresponding to the CGI in the adjacent cell information is unknown, and it is necessary to connect with the adjacent base station corresponding to the adjacent cell information, such as Figure 5 The signaling flow diagram of the ANR as shown in the figure, when the eNB obtains the adjacent cell measurement report reported by the UE, it reports this newly detected adjacent cell relationship to the O&M, and the PCI and the CGI of the adjacent cell are included in the message. After receiving the notification of the eNodeB, the O&M can change the value of the newly discovered NR attribute, i.e., the values of No X2, No HO, and No Remove. If the O&M updates the value of the NR attribute, it will send an NR update message to the eNodeB. After the eNodeB receives the response of the O&M, it updates the attribute value of the corresponding NR. If the O&M does not change the attribute value, it can not send any message. After the attribute value of the NR of the eNodeB is updated successfully, the eNodeB reports the "adjacent cell relationship addition success" to the O&M. After the process is completed, the network switching with the adjacent base station can be started, and the network switching result can be network switching failure or network switching success.

[0121] Step S40: When the network switching result is network switching failure, it is determined that the adjacent base station is a pseudo base station.

[0122] It should be noted that, under normal circumstances, the identification of fake base stations is achieved by the UE terminal equipment collecting information, reporting information such as the CI and signal strength of neighboring base stations to the network through measurement reports. The network combines network topology and configuration information and other relevant data to comprehensively analyze all the data to confirm whether a fake base station exists in a certain area. At the same time, positioning technologies such as GPS and triangulation are used to locate the fake base station, thereby completely eliminating fake base stations. However, this embodiment utilizes the secondary cell search function of ANR and manages NRT to identify new neighboring base stations. Combined with the measurement reports reported by the UE, fake base station identification is achieved. The protection against fake base stations changes from passive protection to active search and prediction.

[0123] In this embodiment, neighboring cell information reported by user equipment in the NSA network is obtained; it is determined whether the neighboring cell information is stored in the local neighboring cell relationship table; when the neighboring cell information is not stored in the neighboring cell relationship table, network handover is performed with the neighboring base station corresponding to the neighboring cell information to obtain the network handover result; when the network handover result is a network handover failure, the neighboring base station is determined to be a fake base station. Therefore, compared with passively searching for fake base stations, this embodiment actively establishes a connection with the neighboring base station of the unknown neighboring cell and realizes fake base station identification based on the connection status, thereby improving the initiative of fake base station identification and ensuring network security.

[0124] Reference Figure 6 , Figure 6 This is a flowchart illustrating the second embodiment of the fake base station identification method based on NSA networks of the present invention. Figure 2 The first embodiment shown presents a second embodiment of the method for identifying fake base stations based on NSA networks.

[0125] In the second embodiment, step S40 includes:

[0126] Step S401: When the network handover result is network handover failure, obtain the neighboring cell operation parameter information reported by the user equipment.

[0127] In a specific implementation, in order to realize the judgment of the network switching result, since the adjacent base station is a newly searched base station, if the adjacent base station is a pseudo base station, there can be no related information in the configuration database, or the establishment of the X2 / Xn connection fails, the switching cannot be completed, thereby causing the switching success rate of the surrounding base station and the user experience rate to decrease, even to drop, and seriously affecting the user perception, so that whether the adjacent base station is a pseudo base station can be judged according to the network switching situation, but sometimes the network switching failure can also be caused by the network connection state, so that the adjacent base station normally accessed can be confirmed as a pseudo base station, in order to improve the accuracy of the pseudo base station identification, the adjacent cell running parameter information is specifically analyzed, so as to judge whether the network switching failure is caused by the network state or the pseudo base station.

[0128] In the embodiment, the adjacent cell running parameter information includes position information, signal strength information, and switching failure number information, and can also include other parameter information, which is not limited in the embodiment.

[0129] In step S402, the index analysis is performed on the adjacent cell running parameter information, and an index analysis result is obtained.

[0130] It should be noted that the adjacent cell running parameter information is analyzed, for example, the network switching failure number information is obtained, and the switching failure number information is compared with a threshold of normal switching, so that whether the index analysis result is a normal network switching failure state can be obtained according to the comparison result.

[0131] In step S403, when the index analysis result reaches an abnormality judgment index, it is determined that the adjacent base station is a pseudo base station.

[0132] In the embodiment, the adjacent cell running parameter information reported by the user equipment can be obtained and analyzed, and when the analysis result meets an abnormal index, it is indicated that the current network switching failure is caused by the pseudo base station, thereby improving the accuracy of the pseudo base station identification.

[0133] In an embodiment, the adjacent cell running parameter information includes position information of the adjacent base station and position information of the adjacent cell.

[0134] The step S403 includes:

[0135] The position information of the adjacent base station and the position information of the adjacent cell are compared in position range, and a position range comparison result is obtained; and the position range comparison result is taken as an index analysis result.

[0136] In a specific implementation, the location information of the neighboring base station can be CGI information, and can also be other forms of parameter information, and the embodiment is not limited in this regard. By obtaining the CGI information of the neighboring base station, the specific location information is obtained, and the location information of the neighboring cell is obtained, so that it can be determined whether the neighboring base station has a neighboring cell. When the neighboring base station has a neighboring cell, the subsequent specific determination is performed. When the neighboring base station does not have a neighboring cell, it is determined that the neighboring base station is a fake base station, so that the location information of the neighboring base station is used to determine the fake base station.

[0137] In an embodiment, the operation parameter information of the neighboring cell includes signal strength information.

[0138] The step S403 includes:

[0139] The signal strength information is compared with a normal signal strength threshold in signal strength, and a signal strength comparison result is obtained. The signal strength comparison result is used as an index analysis result.

[0140] In a specific implementation, since the operation parameter information of the neighboring cell includes signal strength information, it can be determined whether it is a fake base station according to the signal strength information. The normal signal strength threshold can be greater than or equal to -3 dB, and can also be other parameter information, and the embodiment is not limited in this regard. The signal strength information is compared with a normal signal strength threshold in signal strength, for example, when the current signal strength information is -2 dB, it indicates that the current signal strength information is less than the normal signal strength threshold, and it indicates that the signal strength comparison result is an abnormal index, and it is determined that the neighboring base station is a fake base station. The signal strength information of the network side of the neighboring base station is used to determine the fake base station.

[0141] In an embodiment, the operation parameter information of the neighboring cell includes base station handover failure number information.

[0142] The step S403 includes:

[0143] The base station handover failure number information is compared with a handover failure number threshold in number, and a handover failure number comparison result is obtained. The handover failure number comparison result is used as an index analysis result.

[0144] In a specific implementation, since the adjacent cell operation parameter information includes the base station handover failure number information, whether it is a pseudo base station can be determined according to the base station handover failure number information, wherein the handover failure number threshold can be 30 times, and can also be other parameter information, which is not limited in the embodiment. The base station handover failure number information is compared with the handover failure number threshold, for example, when the base station handover failure number information is 50, it is indicated that the base station handover failure number information is greater than the handover failure number threshold, and it is indicated that the handover failure number comparison result is an abnormal index, and it is determined that the adjacent base station is a pseudo base station, so that the determination of the pseudo base station is realized through the base station handover failure number information.

[0145] In the embodiment, the pseudo base station is determined through the position range, the signal strength and the base station handover failure number information, so that it is ensured that the network handover failure is caused by the pseudo base station, rather than other reasons, thereby improving the accuracy of the pseudo base station identification.

[0146] Referring to Figure 7 , Figure 7 FIG. 3 is a flowchart of a third embodiment of a pseudo base station identification method based on an NSA network according to the present application, based on the first embodiment shown in FIG. 2. Figure 2 The third embodiment of the pseudo base station identification method based on the NSA network according to the present application is provided based on the first embodiment shown in FIG. 2.

[0147] In an embodiment, after the step S40, the method further includes:

[0148] In step S401, a blacklist configuration instruction is acquired, and the blacklist configuration instruction is sent to an operation and maintenance center, so that the operation and maintenance center sets the configuration parameter of the allowed parameter indication to an unallowed state according to the allowed parameter indication in the ANR optimization mode.

[0149] In the embodiment, the blacklist configuration instruction can be a blacklist configuration instruction triggered when the pseudo base station is determined, and can also be a blacklist configuration instruction triggered by active triggering, which is not limited in the embodiment. The pseudo base station can be added to the blacklist through the blacklist configuration instruction, so that the operation safety of the network is ensured, wherein the operation and maintenance center is an O&M center.

[0150] In a specific implementation, based on the information of cell signal strength reported by a measurement report (MR), failure record of base station switching, and cell number rule, the network side can statistically analyze the signal abnormality (below -3 dB), the number of times of failure in normal switching, and other pseudo base station discrimination indexes. The management station, i.e., an O&M center, can set the "switching permission indication" (cellAdjCellHCFlag) and the "X2 relationship indication" (cellAdjCellX2Flag) of the adjacent cell pair to be not allowed according to the ANR optimization mode, i.e., add the pseudo base station to the blacklist.

[0151] In an embodiment, after the step S40, the method further comprises:

[0152] obtaining, by the operation and maintenance center, the working parameter information of the pseudo base station; determining the position information of the pseudo base station according to the working parameter information; and positioning the pseudo base station according to the position information.

[0153] In the embodiment, in addition to determining the pseudo base station and adding the pseudo base station to the blacklist, the pseudo base station can also be positioned, so that the pseudo base station can be effectively identified.

[0154] In a specific implementation, the operation and maintenance center can also be an OMC, and the working parameter information can include a mobile country code, a mobile network code, a base station identifier, a site name, a cell identifier, a cell name, a longitude, and a latitude, and can also include other working parameter information. The embodiment does not limit this. The OMC provides a site working parameter information management function, supports import, export, and presentation of site longitude and latitude and other working parameter information, stores the text content that passes the format check in the OMC database as the distance determination basis of low-priority adjacent cells in the adjacent relationship optimization process. The site information management display interface should include at least the working parameter information of the mobile country code, the mobile network code, the base station identifier, the site name, the cell identifier, the cell name, the longitude, and the latitude. Therefore, the accurate position information of the adjacent base station can be obtained through the working parameter information, and the pseudo base station can be positioned through the accurate position information.

[0155] In another embodiment, after the step S40, the method further comprises:

[0156] obtaining the longitude and latitude information and the azimuth information of the adjacent cell where the pseudo base station is located; determining the position information of the pseudo base station according to the longitude and latitude information and the azimuth information; and positioning the pseudo base station according to the position information.

[0157] In the embodiment, the longitude and latitude and the azimuth information of the cell can also be used to infer the position information of the pseudo base station according to the longitude and latitude and the azimuth information of the cell, so as to facilitate on-site investigation and confirmation, so as to obtain the accurate position information of the adjacent base station, and the pseudo base station can be positioned through the accurate position information.

[0158] In an embodiment, the step S30 comprises:

[0159] When the neighboring cell information is not stored in the neighbor relation table, a measurement configuration instruction is constructed according to the neighboring cell information, and the measurement configuration instruction is sent to the user equipment, so that the user equipment extracts the neighboring cell information in the measurement configuration instruction, reads corresponding system information according to the neighboring cell information, and performs network switching with the neighboring base station according to the system information, to obtain a network switching result.

[0160] In this embodiment, the system information of the neighboring cell can be obtained by using the network data collection function of the ANR. However, in order to obtain the system information of the neighboring cell, the eNodeB needs to send a measurement configuration instruction to the UE, and the system information of the neighboring cell can also be obtained through the measurement configuration instruction. The process continues as shown in Figure 5

[0161] In a specific implementation, for the reported cell, the eNodeB checks whether the CGI information of the cell is known. If yes, the handover decision process is performed; if no, the eNodeB constructs a new measurement configuration instruction, sets the trigger mode of the corresponding measurement object to "periodical", sets the reportCGI information element to "TRUE", and includes the PCI of the cell to be reported in the measurement object. After receiving the new configuration instruction, the UE performs measurement, reads the system information of the target cell, including the CGI, the PLMN list, and the TAC. If the required information is successfully read within the system specified time, the UE sends a result report to the eNodeB; if the time is exceeded, the reading operation fails, and no report is sent.

[0162] In an embodiment, the network switching according to the system information and the neighboring base station to obtain a network switching result comprises:

[0163] The system information is added to the neighbor relation table to obtain an updated neighbor relation table; and when the update result of the updated neighbor relation table is update success, the network switching is performed with the neighboring base station to obtain a network switching result.

[0164] ​In the embodiment, after receiving the report, the eNodeB adds a new NR in the NRT neighbor relation table, wherein the local cell is the current serving cell of the UE, the target cell is the NR cell in the report, the cell and base station relation, and the neighboring cell and secondary cell information. The NR record includes the PCI, CGI, PLMN list, and possible TAC / LAC / RAC information of the target neighbor cell, and several attributes (No X2, No HO, and No Remove) of the NR are set to the system default values. After creating the NR, the eNodeB reports the newly detected neighbor relation to the O&M, and the PCI and CGI of the neighbor cell are included in the message.

[0165] After receiving the notification from the eNodeB, the O&M can change the values of the attributes of the newly discovered NR, i.e., No X2, No HO, and No Remove (the O&M is based on the system preset values). If the O&M updates the attribute values, the O&M sends an NR update message to the eNodeB. After receiving the response from the O&M, the eNodeB updates the attribute values of the corresponding NR. If the O&M does not change the attribute values, the O&M can not send any message.

[0166] In the embodiment, the neighbor relation is mainly added successfully. After the neighbor relation is successfully added, the NSA network switching mechanism is used to actively connect with the neighboring cell, so as to realize the switching from the LTE to the 5G network.

[0167] In an embodiment, when the update result of the updated neighbor relation table is update success, the network is switched with the neighboring base station to obtain a network switching result, including:

[0168] When the update result of the updated neighbor relation table is update success, the corresponding network address information is found in the preset configuration data according to the system information; and the network is switched with the neighboring base station according to the network address information to obtain a network switching result.

[0169] In the embodiment, the network address information can be IP (Internet Protocol) address information, and can also be other forms of address information, which is not limited in the embodiment. In the embodiment, the IP address is taken as an example for description.

[0170] In a specific implementation, when the management station receives the "neighbor relation addition success" event reported by the base station, the eNodeB attempts to establish an X2 / Xn connection with the neighboring base station according to the measurement report. The eNodeB checks the configuration database to find the IP address information of the neighboring base station and establishes the X2 / Xn connection. If the neighboring base station is a pseudo base station, there can be no related information in the configuration database, or the establishment of the X2 / Xn connection fails, and the handover cannot be completed. This results in a decrease in the handover success rate and user experience rate of the neighboring base station, even a drop in line, and seriously affects the user perception.

[0171] The embodiment can obtain the system information of the neighboring base station through ANR, find the corresponding network address information in the preset configuration data through the system information, and thus realize the connection with the neighboring base station through the network address information and the active network connection.

[0172] In an embodiment, the step S10 comprises:

[0173] An abnormal system configuration instruction is acquired, and the abnormal system configuration instruction is sent to the user equipment, so that the user equipment reports the neighboring cell information according to the abnormal system configuration instruction.

[0174] In the embodiment, the abnormal system configuration instruction can be an inter-system measurement configuration instruction, that is, an inter-system measurement configuration instruction is triggered at a preset time period, and the inter-system measurement configuration instruction is sent to the UE, so that the UE starts to search for the neighboring cell information.

[0175] In a specific implementation, after the UE establishes the RRC connection and the radio bearer, the eNodeB performs inter-system measurement configuration on the UE, guides the UE to perform B1 measurement for ANR, and continues to configure the message as shown in Figure 5 If the eNodeB wants the UE to search, detect and report the unknown, the trigger type of the measurement object must be set to "periodical", and the measurement purpose is set to "reportStrongestCellsForSON". The frequency point information is configured to the eNodeB by O&M. When the UE measures to meet the specified trigger condition, the measurement B1 report is sent to the eNodeB, and the report contains all the detected NR cells in the list that meet the condition and the measurement metrics such as RSRP of each cell, so as to obtain the neighboring cell information.

[0176] In the embodiment, the abnormal system configuration instruction can be sent to the user equipment, so that the user equipment starts to search for the neighboring cell information, realizes the monitoring of the unknown neighboring base station, and achieves the effective management of the neighboring base station.

[0177] Furthermore, this embodiment of the invention also proposes a storage medium storing a fake base station identification program based on an NSA network. When the fake base station identification program based on an NSA network is executed by a processor, it implements the steps of the terminal network access method described above.

[0178] Since this storage medium adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0179] In addition, refer to Figure 8 This invention also proposes a fake base station identification device based on an NSA network, the fake base station identification device based on an NSA network comprising:

[0180] The acquisition module 10 is used to acquire neighboring cell information reported by user equipment in the NSA network.

[0181] Since this embodiment is based on an NSA network, enabling migration from the eNB side to the gNB side, a connection needs to be established with the gNB side to achieve this migration. Figure 3 The diagram shows a network architecture based on ENDC for NSA. First, the UE accesses normally from the eNB side. Then, a gNB is added as a secondary cell base station, i.e., a neighboring base station. The signaling flow is on the LTE side, and the data flow is on the NR side. The signaling interaction between the base station and the UE is completed by the LTE sending a reconfiguration message. The cell where the eNB is located is the current cell, and the cells adjacent to the current cell are neighboring cells, which can also be called secondary cells. Since the ANR of the NSA network can detect new neighboring cells, the neighboring cell information reported by the user equipment can be obtained. The neighboring cell information includes B1 measurement information used for ANR, and system information of the target cell such as CGI, PLMN list, TAC, LAC, or RAC. It may also include other parameter information. This embodiment does not limit this. The identification of neighboring cells can be achieved through CGI, which facilitates the analysis of neighboring cells.

[0182] To achieve network migration, such as Figure 4The signaling interaction diagram shows that the UE message is a normal access of a 4G terminal, and a default bearer is established. Next, the RRC Connection Reconfiguration to the measurement report MR is three signaling, and the main purpose is to trigger the gNB addition process. After the measurement report is reported, the gNB addition threshold is met, the addition process is triggered, the eNB sends an SgNB addition request message on the X2 interface, the gNB prepares the related resources, and the eNB replies to the SgNB addition request ACK. The ACK message contains a container, including the configuration of the air interface resource. After the eNB receives the ACK message, the container in the ACK message is sent to the terminal in the form of RRC connection reconfiguration to configure the terminal air interface. After the terminal air interface configuration is completed, the RRC connection reconfiguration complete is replied. After the eNB receives the reconfiguration complete message, the SgNB reconfiguration complete message is replied to the gNB on the X2 interface, which means that the air interface of the gNB is ready. The ERAB modification indication and confirmation are to migrate the S1-U from the eNB side to the gNB side, thereby completing the migration of the silent bearer to the split bearer.

[0183] The judging module 20 is configured to judge whether the local neighbor relation table stores the adjacent cell information.

[0184] It should be noted that the local neighbor relation table is an NRT managed by the ANR. The ANR function resides in the eNB and is responsible for managing the NRT. The neighbor detection function is responsible for discovering new neighbors and adding them to the NRT. The neighbor deletion function is responsible for cleaning up useless neighbors. The adjacent cells of the LTE system are automatically discovered by the measurement of the UE, and are no longer completely configured by the O&M. The management and configuration work of the O&M on the eNB neighbor relation is reduced, which is the goal that the SON function hopes to achieve.

[0185] In the embodiment, the unknown adjacent base station in the adjacent cell information can be obtained by judging whether the local neighbor relation table stores the adjacent cell information, so that the unknown adjacent base station can be actively identified as a pseudo base station.

[0186] In the specific implementation, since the neighboring cell information includes CGI information, i.e. cell identification code, the system determines whether the local neighboring cell relationship table contains a CGI. If a CGI is present, it means that the neighboring base station corresponding to the CGI in the neighboring cell information is known. If a CGI is not present, it means that the neighboring base station corresponding to the CGI in the neighboring cell information is unknown, i.e., a new neighboring base station has appeared. In this case, it is necessary to establish a connection with the new neighboring base station to achieve active fake base station search.

[0187] The network handover module 30 is used to perform network handover with the adjacent base station corresponding to the adjacent cell information when the adjacent cell relationship table does not contain the adjacent cell information, so as to obtain the network handover result.

[0188] It is understandable that if the neighboring cell information is not stored in the neighboring cell relationship table, it means that the neighboring base station corresponding to the CGI in the neighboring cell information is unknown, and a connection needs to be established with the neighboring base station corresponding to the neighboring cell information. Figure 5 The diagram illustrates the signaling flow of ANR (Annular Noise Reduction). When the eNB receives the neighbor cell measurement report from the UE, it reports the newly detected neighbor cell relationship to the O&M (Original Node Management). The message includes the PCI and CGI of the neighbor cell. Upon receiving the notification from the eNodeB, the O&M may change the newly discovered NR attributes, specifically the values ​​of No X2, No HO, and No Remove. If the O&M updates the NR attribute values, it sends an NR update message to the eNodeB. After receiving the O&M's response, the eNodeB updates the corresponding NR attribute values. If the O&M does not change the attribute values, it may not send any message. After the eNodeB successfully updates its NR attribute values, it reports "Neighbor cell relationship added successfully" to the O&M. After the process is completed, network handover with neighboring base stations can begin. The network handover result can be either a failure or a success.

[0189] The determination module 40 is used to determine that the adjacent base station is a fake base station when the network handover result is a network handover failure.

[0190] It should be noted that, in general, the judgment of the pseudo base station is responsible for collecting information by the UE terminal device, and the information such as CI and signal strength of the adjacent base station is reported to the network through the measurement report. The network combines the network topology and configuration information and other related data to comprehensively analyze whether there is a pseudo base station in a certain area, and at the same time, through positioning technologies such as GPS and triangulation, the position of the pseudo base station is locked, so as to completely crack down on the pseudo base station. However, the embodiment utilizes the secondary cell search function of ANR and manages NRT, so as to identify new adjacent base stations, and combines the measurement report reported by the UE to realize the identification of the pseudo base station. The protection of the pseudo base station changes from passive protection to active search, and has predictive nature.

[0191] In the embodiment, the adjacent cell information reported by the user equipment in the NSA network is acquired; it is judged whether the adjacent cell information is stored in the local adjacent cell relationship table; when the adjacent cell information is not stored in the adjacent cell relationship table, network switching is performed on the adjacent base station corresponding to the adjacent cell information to obtain a network switching result; when the network switching result is network switching failure, it is determined that the adjacent base station is a pseudo base station. Compared with passive search of the pseudo base station, the embodiment actively establishes a connection with the adjacent base station of the unknown adjacent cell, and realizes pseudo base station identification according to the connection state, thereby improving the initiative of pseudo base station identification and ensuring the safety of the network.
