Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
Because the LTE network adopts the terminal UE, the network authenticates each other through authentication quadruplet (RAND, AUTN, XRES, K-ASME), and completes the integrity protection and encryption of the signaling side through mutual authentication. So theoretically, it is impossible for the UE to successfully camp on the LTE pseudo base station and traffic occurs. Therefore, most of the existing network LTE pseudo base stations are public security pseudo base stations, and the aim is to obtain the IMSI number of the user existing in or passing through a certain geographic area, further analyze and process the user number and the like, and have no pseudo base station behaviors such as fraud short messages and the like in the GSM era.
The UE may have two states, an IDLE state (RRC-IDLE state) and a connected state (RRC-CON state), when passing through the pseudo base station.
When the UE moves to the coverage area of the pseudo base station in an RRC-IDLE state, the UE reselects to the pseudo base station after meeting the R & S reselection criterion because the power of the pseudo base station is generally higher. Reading a system information SIB of the pseudo base station, finding that a TAC value of a tracking area code of the pseudo base station is inconsistent with the current TAC value, and causing reselection failure, and then initiating a tracking area update TAU process by the UE. After the establishment of the radio resource control RRC is completed, the pseudo base station imitates a network side to send an Identity identification Request message Identity Request to attempt to acquire the Identity information of the UE. The UE feeds back an Identity recognition response message Identity response which carries 4G user network information, so that the pseudo base station acquires information such as the IMSI of the user. After obtaining, the pseudo base station refuses to establish connection with the user through the TAU project message, after receiving the TAU project, the UE stops the T3430 timer, stops user data transmission, enters an RRC-IDLE state, and takes different operations according to an EMM Cause value in the refusing message.
Fig. 1 is a schematic diagram of a terminal in a connected state interfered by a pseudo base station in the prior art, as shown in fig. 1, when a UE moves to a coverage of the pseudo base station in an RRC-CON state, due to high interference caused by the pseudo base station, the UE may generate downlink desynchronization, after satisfying an N310 counter, enter a T310 timer, and receive no N311 synchronization indications in the T310 timer, and then enter a cell selection process, and due to a high level of the pseudo base station, the cell selects the pseudo base station, and tries to generate an RRC reestablishment process on the pseudo base station, and after the reestablishment fails, the UE enters an RRC-IDLE state, reads system information SIB of the pseudo base station, finds that a tracking area code TAC value of the pseudo base station is inconsistent with a current value, and initiates a tracking area update TAU flow. After the RRC is established, the pseudo base station imitates the network side to send an Identity Request, and attempts to acquire the UE Identity information. The UE feeds back the Identity response, wherein the Identity response carries the 4G user network information, and therefore the pseudo base station acquires the information such as the IMSI of the user. After obtaining, the pseudo base station refuses to establish connection with the user through the TAU project message, after receiving the TAU project, the UE stops the T3430 timer, stops user data transmission, enters an RRC-IDLE state, and takes different operations according to the EMM Cause value in the refusing message.
Fig. 2 is a schematic diagram of a pseudo base station identification and positioning method according to an embodiment of the present invention, and as shown in fig. 2, an execution subject of the pseudo base station identification and positioning method according to an embodiment of the present invention is a pseudo base station identification and positioning apparatus, where the pseudo base station identification and positioning apparatus may be an individual device or a module in a network side device in a communication network, and the network side device may be a base station, a pseudo base station identification and positioning platform, and the like. For convenience of description, the following description uses network side equipment to characterize the pseudo base station identification positioning apparatus for illustration. The method comprises the following steps:
step S201, acquiring minimization drive test data recorded in a preset time length and reported by a terminal; the minimization of drive tests data comprises a base station cell identification code ECI of the target cell.
Specifically, the 3gpp ran2 working group developed LTE minimization of drive tests in 2009, which outputted a study report TR 36.805. The content includes a requirement case, the content of a UE measurement log, analysis of the influence on terminal power, memory and the like, and related simulation results of situations such as radio link failure and the like.
After the terminal performs MDT configuration, the MDT data recorded in the preset time length is reported periodically or in real time according to the configuration parameters.
And the network side equipment acquires the MDT data recorded in the preset time length reported by the terminal.
MDT data configurations can be classified into signaling-based classes and management/area-based classes. Based on MDT of signaling, an operation maintenance management OAM system selects UE for executing MDT according to permanent identity (IMSI or IMEI) of the UE, and is mainly used for network quality analysis of specific user behavior; the UE selection in management/area class based MDT is performed by the base station E-NodeB node, mainly based on parameters received from the OAM system, the UE radio capabilities and the "MDT allowed flag" received from the core network CN in the relevant signalling procedures.
In the embodiment of the invention, because large data volume statistics is required, the adopted data configuration is based on management/region type MDT data.
Step S202, if the ECI of the target cell is not in a preset database, determining that the target cell is the cell of the pseudo base station, wherein the preset database comprises the ECI of all legal cells in the current network.
Specifically, after acquiring the MDT data recorded within the preset duration reported by the terminal, the network side device parses the ECI of the target cell contained therein, and then determines whether the ECI of the target cell exists in a preset database, where the preset database contains all ECIs in the existing network, the ECIs in the preset database are all legal ECIs, and the ECIs not in the preset database do not conform to the ECI coding rule specified by the operator and belong to illegal ECIs.
And if the ECI of the target cell exists in the preset database, determining that the target cell is the cell of the legal base station.
And if the ECI of the target cell is not in the preset database, determining that the target cell is the cell of the pseudo base station.
The pseudo base station identification and positioning method provided by the embodiment of the invention identifies the pseudo base station according to the abnormal ECI in the minimized drive test data reported by the terminal, and does not need a signaling side to judge the pseudo base station.
Based on any of the above embodiments, further, when the minimization of drive test data is recorded minimization of drive test data, the target cell is a reselection target cell when the terminal has failed in reselection.
Specifically, the MDT data can be divided into logged MDT (logged MDT) and Immediate MDT (Immediate MDT) from the measurement and reporting mode. Logging MDT is typically applied when the UE is in RRC-IDLE state, the main behavior of the UE includes reselection. And the UE collects the cell information according to the system indication time and the indication frequency and reports the measurement report after the RRC-CON state of the UE. The recording MDT part field information is shown in table 1.
TABLE 1 Logged MDT part field information
When the UE moves to the coverage area of the pseudo base station in an RRC-IDLE state, the UE reselects to the pseudo base station after meeting the R & S reselection criterion because the power of the pseudo base station is generally higher. Reading a system information SIB of the pseudo base station, finding that a TAC value of a tracking area code of the pseudo base station is inconsistent with the current TAC value, and causing reselection failure, and then initiating a tracking area update TAU process by the UE.
Therefore, in the embodiment of the present invention, when the minimization of drive test data is recorded minimization of drive test data, the target cell is a reselection target cell when the terminal reselection fails.
The pseudo base station identification and positioning method provided by the embodiment of the invention identifies the pseudo base station according to the abnormal ECI in the minimized drive test data reported by the terminal, and does not need a signaling side to judge the pseudo base station.
Based on any of the above embodiments, further, when the minimization of drive test data is immediate minimization of drive test data, the target cell is a cell to be reconstructed when RRC reconstruction by the terminal fails.
Specifically, the MDT data can be divided into logged MDT (logged MDT) and Immediate MDT (Immediate MDT) from the measurement and reporting mode. And the immediate MDT is applied to the RRC-CON state of the UE and reports the collected network data immediately.
In immediate MDT data, the UE may send a separate connection failure (radio link failure or handover failure) report. Such radio link failure RLF reporting does not require any prior measurement configuration. In other words, the UE supporting this function will actively collect failure related data and report them to the network when it receives a request after the network recovers. These data include radio measurements at connection failure, including location information and the identity of the relevant cell. The reporting mechanism of the information is similar to the record MDT. In other words, after the connection is restored, the UE indicates to the network that there is an RLF report to be reported, and the E-NodeB may ask for the RLF report from the UE. RLF exception event section field information is shown in table 2.
TABLE 2 RLF Exception section field information
When UE moves to a coverage area of a pseudo base station in an RRC-CON state, due to high interference caused by the pseudo base station, the UE can generate downlink desynchronization, enters a T310 timer after meeting an N310 counter, does not receive N311 synchronous instructions in the T310 timer, and further enters a cell selection process, the cell selects the pseudo base station due to the high level of the pseudo base station, tries to generate an RRC reconstruction process on the pseudo base station, and after the reconstruction fails, the UE enters the RRC-IDLE state, reads system information SIB of the pseudo base station, finds that a tracking area code TAC value of the pseudo base station is inconsistent with the current value, and initiates a tracking area update TAU flow.
Therefore, in the embodiment of the present invention, when the minimization of drive test data is the immediate minimization of drive test data, the target cell is a reconstruction target cell when the RRC reconstruction of the terminal fails.
The pseudo base station identification and positioning method provided by the embodiment of the invention identifies the pseudo base station according to the abnormal ECI in the minimized drive test data reported by the terminal, and does not need a signaling side to judge the pseudo base station.
Based on any of the foregoing embodiments, further, after determining that the target cell is a cell of a pseudo base station, the method further includes:
and if the RRC establishment success rate of the main coverage cell of the target position in the preset time is lower than a preset threshold value, determining that the target position is the position of a pseudo base station, wherein the target position is the longitude and latitude of the terminal contained in the MDT data.
Specifically, fig. 3 is a schematic flowchart of a pseudo base station identification and positioning logic provided in the embodiment of the present invention, and as shown in fig. 3, after a target cell is preliminarily identified as a cell of a pseudo base station, a position of the pseudo base station needs to be determined.
Normally, the RRC establishment success rate of the cell is maintained in a reasonable interval, but if the cell is interfered by the pseudo base station, the RRC establishment success rate of the normal cell is also reduced to a low level. After the target cell is preliminarily identified to be the cell of the pseudo base station, the position of the pseudo base station can be further determined according to the RRC establishment success rate of the main coverage cell where the UE is located.
If the success rate of establishing the RRC in the primary coverage cell of the location of the UE within the preset duration is lower than a preset threshold, which may be set according to the index of the whole network, for example, set to 10%, and the like, it is determined that the location of the UE is the location of the pseudo base station, where the location of the UE is determined by the longitude and latitude of the UE included in the minimization of drive test data.
The pseudo base station identification and positioning method provided by the embodiment of the invention identifies the pseudo base station according to the abnormal ECI in the minimized drive test data reported by the terminal, and does not need a signaling side to judge the pseudo base station. And the accurate position of the pseudo base station can be determined according to the longitude and latitude of the UE in the minimization of drive test data.
Based on any of the above embodiments, further before the obtaining of the minimization of drive test data recorded within the preset time length and reported by the terminal, the method further includes:
and issuing minimization drive test configuration information to the terminal, wherein the minimization drive test configuration information is used for indicating the terminal to report minimization drive test data.
Specifically, when the minimization of drive test data is recorded minimization of drive test data, before the terminal reports the minimization of drive test data, the terminal needs to be configured correspondingly to instruct the terminal to report the recorded minimization of drive test data.
Fig. 4 is a schematic diagram of a measurement configuration and measurement reporting mechanism for recording MDT according to an embodiment of the present invention, and as shown in fig. 4, an E-NodeB node creates a recording MDT measurement configuration according to configuration parameters received from an OAM system, and issues an MDT measurement configuration message to a UE in an RRC-CON state through a dedicated RRC message. Relevant configuration parameters include: recording time interval (Logging Duration), recording Duration, etc. And the UE stores the measurement configuration after receiving the measurement configuration, and performs corresponding recording measurement according to the stored configuration information after the UE enters an RRC-IDLE state. And after the UE enters the RRC-CON state, the expanded indication of 'whether the recorded data exists' is used in RRM signaling (such as RRC connection establishment completion message) and sent to the E-NodeB node, if the recorded data exists in the UE, the E-NodeB node sends a UE information request to the UE to ask for the report of the measured data, and the UE reports the measurement to the E-NodeB node in the UE information response. If all the measurement records cannot be transmitted in one UE information request/response process, multiple interactive processes can be performed between the E-NodeB node and the UE.
When the E-NodeB node learns that the UE has the recorded data, the E-NodeB node does not need to acquire the recorded data immediately and can ask for the recorded data at any time in the process of connecting with the UE. Therefore, the UE will keep for some time (typically no more than 48 hours) for data that is not reported. The UE also needs a certain memory to store data, for example, the UE supporting R10 MDT requires at least 64KB of memory space for recording MDT logging measurement data.
In addition, as shown in fig. 3, the minimization of drive test data reported by the terminal may be stored in a dedicated FTP server, and the pseudo base station identification and positioning platform may directly extract relevant data from the FTP server when needed.
The pseudo base station identification and positioning method provided by the embodiment of the invention identifies the pseudo base station according to the abnormal ECI in the minimized drive test data reported by the terminal, and does not need a signaling side to judge the pseudo base station. And the accurate position of the pseudo base station can be determined according to the longitude and latitude of the UE in the minimization of drive test data.
Based on any of the foregoing embodiments, further, after determining that the target location is the location of the pseudo base station, the method further includes:
and displaying the position of the pseudo base station in a Geographic Information System (GIS).
Specifically, in the embodiment of the invention, after the position of the pseudo base station is determined, the position GIS of the pseudo base station is displayed, so that a user can intuitively determine the position of the pseudo base station to take further measures.
The pseudo base station identification and positioning method provided by the embodiment of the invention identifies the pseudo base station according to the abnormal ECI in the minimized drive test data reported by the terminal, and does not need a signaling side to judge the pseudo base station. And the accurate position of the pseudo base station can be determined according to the longitude and latitude of the UE in the minimization of drive test data.
Based on any of the foregoing embodiments, further before determining that the target cell is a cell of a pseudo base station, the method further includes:
and cleaning the minimization of drive test data, and removing ECI data which cannot be analyzed by the terminal.
Specifically, as shown in fig. 3, after acquiring the minimization of drive test data reported by the terminal, the network side device needs to clean the minimization of drive test data in order to avoid the influence of data errors on the identification accuracy of the pseudo base station. For example, the ECI data that the terminal cannot analyze and the abnormal ECI data of the city boundary are removed.
For example, the results of a certain minimization of drive tests data after being washed are shown in table 3.
