Detailed Description
The following description of the technical solutions in the embodiments of the present disclosure will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only some embodiments of the present disclosure, not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.
Some embodiments of a method of checking location information of a base station of the present disclosure are described below in conjunction with fig. 1.
Fig. 1 is a flow chart of some embodiments of a method of checking location information of a base station of the present disclosure. As shown in fig. 1, the method of this embodiment includes: steps S102 to S106.
In step S102, the identity of the base station to which the terminal is connected at each moment is determined according to the relevant signaling of the terminal.
In some embodiments, signaling on a signaling link is collected from a mobile communications network; and determining related signaling of the terminal according to the identification of the terminal carried in the signaling. For example, signaling may be collected from various network elements such as base stations, switches, HLRs (Home Location Register, home location registers), etc. The identity of the terminal is for example, MDN (Mobile Directory Number, mobile subscriber directory number), IMSI (International Mobile Subscriber Identification Number, international mobile subscriber identity), etc., but is not limited to the illustrated examples. The signaling may also carry information about the base station to which the terminal is connected, such as an identity of the base station, a Cell identity (e.g., cell ID), and so on. The identity of the corresponding base station may be determined from the cell identity. The signaling also corresponds to a specific timestamp for determining the time of transmission or reception of the signaling.
In step S104, the positional relationship between the base stations is determined based on the identities of the base stations to which each terminal is connected at each time.
The positional relationship includes: adjacent relationship. Aiming at the scene of 5G non-independent networking, a plurality of base stations with different network systems coexist, for example, the coverage area of a 4G base station is large, the 5G base station is positioned under the coverage area of the 4G base station, and a terminal can be connected with a plurality of base stations at the same time. The positional relationship may further include: covering the relationship.
In some embodiments, for each terminal, a base station connection change track of the terminal is generated according to the identities of the base stations to which the terminal is connected at various moments. For each base station, determining the number of connection changes between the base station and other base stations in preset time according to the connection change track of the base station of each terminal in the preset time, and taking other base stations with the corresponding connection change number greater than a first threshold value as adjacent base stations of the base station.
The base station connection change track of the terminal may be the identities of the respective base stations arranged in time sequence. According to the base station connection change track of the terminal, two base stations connected with the terminal in sequence can be determined, and the conditions of the two base stations before and after switching or the two base stations before and after cell reselection can be adopted. For each base station a and each terminal, it may be determined that one base station to which the terminal is connected before the base station a is the previous base station of the base station a or one base station to which the terminal is connected after the base station a is the subsequent base station of the base station. Further, a plurality of previous base stations and/or a plurality of next base stations may be obtained for the base station a, and for each previous base station, the number of times the previous base station occurs before the base station a within a preset time (for example, 1 hour, which may be flexibly configured) may be used as the number of connection change times between the previous base station and the base station a. If the number of connection changes corresponding to the previous base station is greater than the corresponding threshold, the previous base station may serve as a neighbor base station for the base station A. Alternatively, the number of times the latter base station occurs after the base station a within a preset time (e.g., 1 hour, flexibly configurable) may be used as the number of connection changes between the latter base station and the base station a for each latter base station. If the number of connection changes corresponding to the latter base station is greater than the corresponding threshold, the latter base station may serve as a neighbor base station for the base station a.
The movement process of the terminal may be opposite, and thus, the same base station may occur before or after the base station a, that is, in the case where the previous base station and the subsequent base station are the same base station B, the number of times the base station B occurs before the base station a and the number of times the base station B occurs after the base station a within a preset time (for example, 1 hour, which is flexibly configurable) may be added as the number of connection change times between the base station B and the base station a. If the number of connection changes between base station B and base station A is greater than the first threshold, base stations A and B are neighbor base stations to each other. The first list may be generated for each base station in order of high to low number of connection changes between the other respective base stations and the base station.
In other embodiments, for each terminal, generating a base station connection change track of the terminal according to the identifiers of the base stations connected by the terminal at each moment, and determining a plurality of base stations connected by the terminal at the same time according to the base station connection change track of the terminal; for each base station, determining the number of times that the base station and other base stations are simultaneously connected within preset time, and taking other base stations with the corresponding times larger than a second time threshold as multi-connection base stations of the base station; and determining the base station and the multi-connection base station as adjacent base stations under the condition that the base station and the multi-connection base station are the same standard base stations.
Under the multi-connection scene, the terminal may connect a plurality of base stations at the same time, and under the condition that the plurality of base stations are of the same system (for example, 4G or 5G), the plurality of base stations are generally adjacent base stations, and the accuracy of determining the adjacent base stations can be improved through the number of times of multi-connection of the terminal.
Further, in still other embodiments, in the case that the base station and the multi-connection base station are base stations of different standards, the coverage relationship between the base station and the multi-connection base station is determined according to coverage ranges of base stations of various network standards. For example, in the case that the base station is a 4G base station and the multi-connection base station is a 5G base station, the coverage area of the base station is larger than that of the multi-connection base station, and the two base stations are in a coverage relationship.
In some embodiments, determining a communication behavior type of the terminal at each moment according to related signaling of the terminal, and associating an identifier of the base station at each moment with the communication behavior type; after the base station connection change track of the terminal is generated, determining whether the communication behavior type corresponding to the identification of each base station is a preset type, and deleting the identification of the base station corresponding to the preset type in the base station connection change track of the terminal.
The communication behavior types include, for example: one or more of calling, short message, turning on, turning off, registering, logging off, location updating, surfing are not limited to the illustrated examples. The communication behavior of the terminal can be determined according to the type of the related signaling of the terminal, and some communication behaviors, such as restarting after a period of time after the user is shut down, may cause huge or inaccurate connection change of the base station, the behaviors of the types can be used as preset types of behaviors, and the identification of the base station corresponding to the preset types is deleted in the connection change track of the base station of the terminal, so that the accuracy of the subsequent process is further improved, and erroneous judgment is effectively avoided.
In step S106, the positional relationship between the base stations is compared with the static positional information preconfigured by each base station, and whether the static positional information of the base station is wrong is determined according to the comparison result.
The distance between two base stations can be calculated according to static position information (e.g., longitude and latitude) preconfigured by each base station, and the distance calculation formula of any two points on the earth in the prior art can be referred to, and is not limited to the illustrated example. The second list may be generated in a distance-to-near or near-to-far order according to the distance between any two base stations.
In some embodiments, if it is determined that the two base stations belong to the neighboring relationship according to the position relationship between the base stations, and if it is determined that the distance between the two base stations is greater than the first distance threshold according to the static position information of the two base stations, the static position information of the two base stations is determined to be suspected error information. I.e. it is determined that the two base stations are adjacent (obtainable with the first list) according to the connection change trace of the terminal, but the two base stations are far apart (obtainable with the second list) according to the static location information, the static location information of the two base stations may be erroneous.
In other embodiments, if it is determined that the two base stations do not belong to the neighboring relationship according to the position relationship between the base stations, and if it is determined that the distance between the two base stations is less than the second distance threshold according to the static position information of the two base stations, the static position information of the two base stations is determined to be suspected error information. I.e. the two base stations are closely related to each other (obtainable with the second list) according to the static location information, but the two base stations are not adjacent (obtainable with the first list) according to the connection change track of the terminal, the static location information of the two base stations may be wrong.
In still other embodiments, if it is determined that the two base stations belong to the coverage relationship according to the position relationship between the base stations, and it is determined that the distance between the two base stations is greater than the third distance threshold according to the static position information of the two base stations, the static position information of the two base stations is determined to be suspected error information. Or determining that the covered base station is not in the maximum coverage area of the covered base station according to the static position information of the two base stations, and determining the static position information of the two base stations as suspected error information. That is, it is determined that the two base stations are in a coverage relationship according to the connection change track of the terminal, but the two base stations are far apart or do not belong to the coverage relationship according to the static position information, and the static position information of the two base stations may be wrong.
In still other embodiments, if it is determined that the two base stations do not belong to the coverage relationship according to the location relationship between the base stations, and if it is determined that one base station is located under the coverage of another base station according to the static location information of the two base stations, the static location information of the two base stations is determined to be suspected error information. That is, the two base stations belong to the coverage relationship according to the static position information, but it is determined that the two base stations do not belong to the coverage relationship according to the connection change track of the terminal, and the static position information of the two base stations may be wrong.
The suspected error information may be directly determined as error information, and relevant information (e.g., identification, static location information, etc.) of the corresponding base station may be output. Other information can be further combined, and accuracy of static position information error judgment is improved. In some embodiments, the static location information is taken as suspected error information, and for each suspected error base station, according to the number of the suspected error base stations determined as the suspected error base stations by the base stations adjacent to the suspected error base station, at least one item of location information of a network device to which the suspected error base station belongs, whether the static location information of the suspected error base station is wrong or not is determined. Here, the base stations adjacent to the suspected wrong base station are determined according to the positional relationship between the base stations, that is, according to the base station connection change track of the terminal.
For example, if the number of base stations adjacent to the suspected wrong base station is determined to be greater than the number threshold, the static position information of the suspected wrong base station is determined to be wrong. For example, the base station a is a suspected error base station, and the base station B, C, D is a neighboring base station of the base station a, which are all determined to be suspected error base stations according to the above method. This may indicate that base station B, C, D adjacent to base station a is far from base station a. In this case, if the probability that the base station a is the wrong base station is high, it is determined that the static location information of a is wrong.
