Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method and an apparatus for verifying a base station location, and a network management system.
Background
Traditional spectrum resources are allocated mainly in a licensed manner and an unlicensed manner. Generally, the authorization mode refers to issuing a license plate to a primary user through a supervision organization, so that the primary user obtains an exclusive use right of a certain spectrum resource, and the authorized primary user needs to guarantee service quality. The authorization-free mode does not need to issue a specific license plate, does not limit the access users or operators, provides services in a best effort mode and has no requirement on service quality.
The Spectrum sharing Access mode refers to Spectrum sharing with a primary user through predefined cooperation conditions, such as when the primary user does not use the Spectrum in a specific area or at a specific time, other services are allowed to share and Access the Spectrum, and the main Spectrum sharing Access modes include a L SA (L granted Shared Access) mode defined by European CEPT (Conference of European Post and telecommunication Conference) and a Federal Communications Commission (Federal Communications Commission, Communications Commission) mode defined by the United states of America.
The key of spectrum sharing access is to obtain the location information of a base station, and obtain information such as usable frequency and time according to the surrounding radio environment and the frequency use condition of a primary user, so as to complete spectrum sharing work. Obtaining accurate base station location information is therefore critical to spectrum sharing access.
The conventional base station location positioning method mainly includes the following two methods:
firstly, manual input is carried out, namely, when the base station is installed, an installer finishes the input work of the position information (such as longitude and latitude) of the base station, and then the manually input position information of the base station is sent to a network management system;
the other is automatic input, that is, a GPS (Global Positioning System) receiver is installed in the base station, and the Positioning information obtained by the GPS is directly transmitted to the network management System.
Both methods cannot confirm whether the position information of the base station is tampered, so that the accuracy of the position information of the base station cannot be guaranteed, and potential safety hazards exist in a communication system.

Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth to illustrate, but are not to be construed to limit the scope of the invention. All embodiments obtained by the spirit of the present invention will fall within the scope of the present invention for a person of ordinary skill in the art without any inventive work.
Example one
Fig. 1 is a flowchart of a method for verifying a location of a base station according to an embodiment of the present invention. As shown in fig. 1, in this embodiment, the method for verifying the location of the base station may include the following steps:
step 101, receiving position information reported by a target base station, wherein the target base station is a newly deployed base station;
the location information may be expressed in terms of latitude and longitude, for example (X1, Y1).
The target base station may report location information such as longitude and latitude of the target base station to the network management system when the target base station is deployed.
Step 102, determining at least one auxiliary base station of the target base station according to the position information;
in this step, it is assumed that the target base station is at the position indicated by the reported position information, and at least one auxiliary base station of the target base station is determined on the premise of this.
In this embodiment of the present invention, determining at least one assisting base station of the target base station according to the location information may include: and selecting at least one base station of which the distance from the position represented by the position information is smaller than a preset distance threshold value as an auxiliary base station of the target base station.
In a specific implementation procedure, selecting at least one base station, as an assisting base station of the target base station, where a distance between the assisting base station and the position represented by the position information is smaller than a preset distance threshold, may include: and randomly selecting at least one base station as an auxiliary base station of the target base station from the base stations of which the distance from the position represented by the position information is less than a preset distance threshold value.
In a specific implementation procedure, selecting at least one base station, as an assisting base station of the target base station, where a distance between the assisting base station and the position represented by the position information is smaller than a preset distance threshold, may include: and selecting at least one base station with the signal strength reaching the position represented by the position information higher than a preset signal strength threshold value as an auxiliary base station of the target base station from the base stations with the distance to the position represented by the position information smaller than the preset distance threshold value.
In this embodiment of the present invention, determining at least one assisting base station of the target base station according to the location information may include: and selecting at least one base station with the signal strength reaching the position represented by the position information higher than a preset signal strength threshold value as an auxiliary base station of the target base station.
And 103, verifying the position information based on the communication condition between the target base station and the at least one auxiliary base station.
The communication situation between the target base station and the at least one assisting base station is the actual communication situation. Since the determination of the assisting base station is based on the premise that the target base station is located at the position indicated by the position information reported by the target base station, if the position information reported by the target base station is accurate (or valid or trusted), the communication condition between the target base station and the assisting base station will necessarily conform to the reasoning based on the position information. Conversely, if the communication between the target base station and the assisting base station does not conform to the inference based on the location information, it indicates that the location information is inaccurate (or invalid or untrustworthy).
The base station position verification method of the embodiment of the invention verifies the accuracy of the position information reported by the target base station by utilizing the communication condition between the auxiliary base station and the target base station determined by the position information reported by the target base station, and avoids false alarm caused by tampering the position information of the target base station, thereby ensuring the accuracy and the authenticity of the position information reported by the target base station, providing accurate basis for spectrum sharing access and improving the safety of a communication system.
Example two
Based on the method for verifying the location of the base station provided in the first embodiment, the embodiment of the present invention specifically describes the step S103.
Fig. 2 is a schematic flowchart of step S103 in fig. 1. As shown in fig. 2, in this embodiment, the foregoing step S103 may include the following sub-steps:
step S201, a neighbor cell list obtained by monitoring one side between a target base station and at least one auxiliary base station and the other side is obtained;
among these, one possible scenario is: one is a target base station and the other is at least one assisting base station. In this case, obtaining the neighbor cell list obtained by one side listening to the other side between the target base station and the at least one assisting base station may include: and acquiring a first neighbor list obtained by the target base station monitoring at least one auxiliary base station.
Among these, another possible scenario is: one is at least one assisting base station and the other is a target base station. In this case, obtaining the neighbor cell list obtained by one side listening to the other side between the target base station and the at least one assisting base station may include: and acquiring at least one second neighbor list obtained by the at least one auxiliary base station respectively monitoring the target base station.
Step S202, verifying the validity of the position information according to the relationship between the acquired neighbor list and the intercepted party between the target base station and at least one auxiliary base station.
The neighbor cell list is a list generated by the interception party.
The base station position verification method of the embodiment of the invention verifies the accuracy of the position information reported by the target base station by utilizing the relationship between the neighbor list obtained by interception between the auxiliary base station and the target base station and the intercepted party, which is determined by the position information reported by the target base station, and avoids false alarm caused by tampering of the position information of the target base station, thereby ensuring the accuracy and the authenticity of the position information reported by the target base station, providing accurate basis for spectrum sharing access and improving the safety of a communication system.
EXAMPLE III
Based on the base station location verification method provided in the second embodiment, in step S201, under the condition that the first neighbor cell list obtained by the target base station monitoring the at least one auxiliary base station is specifically obtained, the embodiment of the present invention specifically describes step S202.
Fig. 3 is a schematic flowchart of step S202 in fig. 2. As shown in fig. 3, in this embodiment, the foregoing step S202 may include the following sub-steps:
step S301, determining the proportion of the auxiliary base station appearing in the first neighbor cell list in the at least one auxiliary base station, and recording as a first proportion;
assuming that the total number of assisting base stations is 10, when the target base station listens to all of the 10 assisting base stations, and the number of assisting base stations appearing in the first neighbor list is 6, the first percentage is equal to 60%.
Step S302, verifying the validity of the position information according to the relation between the first ratio and a preset first ratio threshold.
Wherein the first proportional threshold may be determined based on empirical values.
In this embodiment of the present invention, verifying the validity of the position information according to the relationship between the first proportion and the preset first proportion threshold may include: and confirming that the position information is valid when the first occupation ratio is larger than or equal to a first ratio threshold.
The location information is valid, i.e. the location information is accurate or authentic, at which point it can be assumed that the location information has not been tampered with. For example, assuming that the first proportion threshold is 80% and the first proportion is 90%, since the first proportion is larger than the first proportion threshold, the position information is valid.
In this embodiment of the present invention, verifying the validity of the position information according to the relationship between the first proportion and the preset first proportion threshold may include: in the case where the first duty ratio is smaller than the first proportional threshold, it is confirmed that the positional information is invalid.
The location information is invalid, i.e., the location information is inaccurate or untrusted, and the location information may be considered tampered. For example, assuming that the first scale threshold is 80% and the first duty ratio is 50%, since the first duty ratio is smaller than the first scale threshold, the position information is invalid.
The base station position verification method of the embodiment of the invention verifies the accuracy of the position information reported by the target base station by utilizing the relation between the neighbor list obtained by the target base station monitoring the auxiliary base station and the auxiliary base station, and avoids false alarm caused by tampering the position information of the target base station, thereby ensuring the accuracy and the authenticity of the position information reported by the target base station, providing accurate basis for spectrum sharing access and improving the safety of a communication system.
Example four
Based on the base station location verification method provided in the second embodiment, in step S201, under the condition that at least one second neighbor list obtained by at least one assisting base station respectively intercepting a target base station is specifically obtained, the embodiment of the present invention specifically describes step S202.
Fig. 4 is another schematic flow chart of step S202 in fig. 2. As shown in fig. 4, in this embodiment, the foregoing step S202 may include the following sub-steps:
step S401, determining the proportion of a second neighbor list containing the target base station in at least one second neighbor list, and recording as a second proportion;
each assisting base station intercepting the target base station generates a second neighbor list, and if the assisting base station intercepts the target base station, the target base station appears in the second neighbor list generated by the assisting base station. Conversely, if the assisting base station does not sense the target base station, the target base station will not appear in the second neighbor list generated by the assisting base station.
Step S402, verifying the validity of the position information according to the relation between the second proportion and a preset second proportion threshold.
Wherein the second proportional threshold may be determined from empirical values.
In this embodiment of the present invention, verifying the validity of the position information according to the relationship between the second proportion and the preset second proportion threshold may include: and confirming that the setting information is valid when the second ratio is greater than or equal to the second ratio threshold.
In this embodiment of the present invention, verifying the validity of the position information according to the relationship between the second proportion and the preset second proportion threshold may include: and confirming that the position information is invalid when the second proportion is smaller than the second proportion threshold value.
The base station position verification method of the embodiment of the invention verifies the accuracy of the position information reported by the target base station by utilizing the relation between the neighbor list obtained by the auxiliary base station for monitoring the target base station and the target base station, and avoids false alarm caused by tampering the position information of the target base station, thereby ensuring the accuracy and the authenticity of the position information reported by the target base station, providing accurate basis for spectrum sharing access and improving the safety of a communication system.
The method for verifying the location of the base station provided by the embodiment of the invention is further described in detail by way of examples.
Example 1
In this example, the network management system determines whether the location information reported by the target base station is valid according to the neighbor list of the target base station, including the following steps:
the target base station reports the position information to a network management system, wherein the target base station is a newly deployed base station;
the network management system selects an auxiliary base station according to the position information reported by the target base station;
the network management system sends the frequency information of the auxiliary base station, the interception auxiliary information of the wireless access technology and the like to the target base station;
the target base station monitors the signal of the adjacent cell according to the monitoring auxiliary information sent by the network management system and reports the adjacent cell list to the network management system;
and the network management system verifies the position of the target base station according to the relation between the neighbor list reported by the target base station and the auxiliary base station.
The target base station may monitor or access user search of the base station through a receiver of the base station to obtain information of neighboring cells, and add information of multiple neighboring cells with strong signal strength to a neighboring Cell list, where the neighboring Cell list generally includes an ECGI (E-UTRAN Cell Global Identifier, which is composed of P L MN + Cell identity), a Physical Cell identity (PCI, Physical Cell ID), and a radio access technology of each Cell.
When the position of the target base station is verified, the network management system compares the base stations in the neighbor cell list reported by the target base station with the identifiers of the auxiliary base stations, and if the proportion of the auxiliary base stations in the neighbor cell list is higher (compared with a preset proportion threshold value), the position information reported by the target base station is considered to be trustable. And if the proportion of the auxiliary base station in the neighbor cell list is low (compared with a preset proportion threshold), the position information reported by the target base station is considered to be unreliable. Wherein the ratio threshold for comparison may be self-configured by the network management system.
Example two
In this example, the network management system determines whether the reported position of the target base station is valid according to the neighboring cell information of the auxiliary base station, including the following steps:

the auxiliary base station monitors the adjacent cell signals according to the monitoring auxiliary information sent by the network management system and reports the adjacent cell list to the network management system;
and the network management system verifies the position of the target base station according to the relation between the neighbor cell list reported by the auxiliary base station and the target base station.
The auxiliary base station may intercept or access user search of the base station through a receiver of the base station to obtain information of neighboring cells, and add information of multiple neighboring cells with strong signal strength to a neighboring cell list, where the neighboring cell list generally includes ECGI, physical cell identity PCI, and radio access technology of each cell. And the auxiliary base station reports the obtained neighbor cell list to a network management system.
When the position of the target base station is verified, the network management system compares the base stations in the neighbor list of the auxiliary base station with the identification of the target base station, and if the proportion of the target base station appearing in the neighbor list of at least one auxiliary base station is higher (compared with a preset proportion threshold), the position information reported by the target base station is considered to be trustable. And if the proportion of the target base station appearing in the neighbor list of at least one auxiliary base station is lower (compared with a preset proportion threshold), the position information reported by the target base station is considered to be untrustworthy. Wherein the ratio threshold for comparison may be self-configured by the network management system.
