In general, the mobile communication service area is divided by the service coverage area of the base station, and the service area is designed such that the base station coverage areas overlap in order to provide a service without disconnection while the mobile communication terminal moves. That is, the service coverage area of the base station is divided into a plurality of cells, and is designed such that at least one cell adjacent to one cell and the service edge area overlap each other.

However, there may be a case where three or more base station signals are introduced at a similar strength in a specific region, and in this case, multiple handoffs occur, not only wasting frequency resources and channel resources of the base station, but also disconnecting due to frequent handoffs. Problems occur.

In order to solve such a problem in the signal overlap area, after the customer complaint is received, the operator measures the quality information of the corresponding field (signal overlap area) and checks the result to solve the problem. Therefore, since the problem of the signal overlap area can be detected only after the customer complaint is received, the quality of service is deteriorated, and a lot of manpower and time are required to identify the signal overlap area in advance.

As shown in the drawing, the field information analyzing apparatus 100 divides the service area of each base station into unit fields, collects quality measurement information from the quality management system 20, and collects the base station management apparatus ( The information analysis server 10 collects configuration information of each base station from the base station manager 30, analyzes the signal strength for each base station PN code for each unit field, and determines whether or not the signal overlap region is based on the signal strength analysis result. At the request of the server 10, the map server 12 displaying the service status of the unit field on the map, and the user who receives a command from the operator for analyzing field information and provides the operator with the processing result of the map server 12. Interface 14.

Here, the quality measurement information collected by the information analysis server 10 from the quality measurement information management device 20 may include a quality measurement position, PN code information at the quality measurement position, signal-to-noise ratio (Ec / Io) for each PN code, The received signal strength and handoff information are included. The handoff information is set as a handoff area when the number of detected PN codes is two or more according to the number of PN codes detected at the quality measurement position. And, for this purpose, the quality measurement information management apparatus 20 should collect and manage the quality measurement information every designated period (for example, once a day).

In addition, the base station configuration information collected by the information analysis server 10 from the base station management apparatus 30 includes base station location information, pilot signal information, frequency information allocated to each base station, and the like.

The information analysis server 10 collects the above quality measurement information and the base station configuration information from the quality measurement information management device 20 and the base station management device 30 and uses them in a unit field (for example, 10m * 10m). A representative signal-to-noise ratio value of a PN code is selected. If a plurality of signal-to-noise ratio values exist for a corresponding PN code, the median is selected as the representative value. When the median value is selected as the representative value, if the total number n of signal-to-noise ratio values is odd, the (n + 1) / 2th value is the median value, and when n is even, the n / 2th value and (n / 2) The average value of the + 1st value is the median value.

If there are two or more PN codes used in the corresponding unit field, a representative signal-to-noise ratio value of each PN code is selected, and the plurality of PN codes are arranged in order of strong signal strength according to the result. In this case, the PN codes are preferably arranged up to a specified maximum number (for example, six), and the sorted plurality of PN codes are divided into a serving PN code and an active PN code.

In this way, the representative signal-to-noise ratio of the PN code is selected for each unit field, and after the PN codes are arranged in the order of the strongest signal strength, the fields having the number of serving PN codes and active PN codes (for example, three or more) are extracted. This area is managed as a signal overlap area.

In addition, when the operator requests to display the service status of a specific field on the map, the map server 12 is driven to display quality measurement information of the corresponding field, whether the signal overlaps the area, and the like on the map. If the operator requests to indicate the bad signal area, the signal overlap area extracted as described above is displayed on the map.

FIG. 2 is a detailed configuration diagram of the information analysis server shown in FIG. 1.

As shown, the information analysis server 10 is a quality measurement information collection unit for collecting the quality measurement information from the unit field management unit 110, the quality measurement information management device 20 for managing the service area by the specified unit ( 120, the base station information collecting unit 130 collecting base station configuration information from the base station management device 30, representative value selecting unit 140 for determining the representative signal-to-noise ratio value of each PN code for each unit field, PN for each unit field PN code sorter 150 for listing codes by signal strength, signal overlap region selection unit 160 for determining whether a signal overlap region is based on the number of serving PN codes and active PN codes present in a unit field, and unit fields Map server driver 170 for driving the map server 12 to display the service status on the map and for storing map information, quality measurement information, base station configuration information, signal overlap area information, etc. And a database (180).

The function of each component will be described in detail as follows.

First, the unit field manager 110 divides a service area of each base station into a unit field of a designated unit, for example, 10m * 10m, and assigns and manages an identifier for each field.

The quality measurement information collection unit 120 measures the quality including the quality measurement position, PN information at the quality measurement position, signal-to-noise ratio (Ec / Io), received signal strength, and handoff information from the quality measurement information management device 20. Collects the information and stores the information in the unit information DB 184 by dividing each unit field, and the handoff information is two or more PN codes detected according to the number of PN codes detected in the unit field. It is set to be a handoff area.

The base station information collecting unit 130 collects base station configuration information including base station location information, pilot signal information, frequency information allocated to each base station, etc. from the base station management device 30, and divides the information into base unit management information by collecting each unit field. Save at 184.

Next, the representative value selecting unit 140 determines the representative signal-to-noise ratio value for each PN code used in the unit field by referring to the signal-to-noise ratio for each PN code collected by the quality measurement information collecting unit 120. If there are a plurality of measured signal-to-noise ratio values for the PN code, the median value is determined as a representative value.

When a plurality of PN codes are used in the unit field, the PN code sorter 150 refers to the representative values of the signal-to-noise ratios for each PN code determined by the representative value selector 140, and arranges them in the order of strong signal strength. It distinguishes between serving PN code and active PN code. In this case, when there are a plurality of PN codes in the unit field, it is preferable to align up to six PN codes. Among them, the upper three having the strongest signal strength are serving PN codes and the lower three are active PN codes. Can be distinguished.

The signal overlapping region selecting unit 160 refers to the processing result of the PN code alignment unit 150 and signals a unit field having a number (eg, three) or more of the serving PN code and the active PN code respectively specified in the unit field. The overlapping area is determined and stored in the signal overlapping area DB 186.

On the other hand, when the operator requests the information on the service status of a particular unit field through the user interface 14, the map server driver 170 drives the map server 12 and refers to the unit field with reference to the map DB 182 Transmit map information, including, and display quality measurement information on the corresponding unit field, whether the signal overlaps the region, and the like on a map. If the operator requests to display which area the signal overlap area is, the information stored in the signal overlap area DB 186 and the map DB 182 is transmitted to the map server 12 for display.

3 is a flowchart illustrating a field information analysis method according to an embodiment of the present invention.

In order to provide the method for analyzing field information of the present invention, the field information analyzing apparatus must first perform a process of dividing and managing a service area of each base station into fields of a designated unit (S101).

The quality measurement information collecting unit 120 and the base station information collecting unit 130 collect quality measurement information and base station configuration information from the quality measurement information management device 20 and the base station management device 30, respectively, and collect the collected information DB. In step 184, it stores (S103, S105). Here, the quality measurement information includes a quality measurement position, PN code information at the quality measurement position, signal-to-noise ratio (Ec / Io), received signal strength, and handoff information for each PN code, and handoff information at the quality measurement position. If the number of detected PN codes is two or more according to the number of detected PN codes, it is set as a handoff area. In addition, the base station configuration information includes base station location information, pilot signal information, frequency information allocated to each base station, and the like.

After collecting the information necessary for analyzing the field information, the representative value selecting unit 140 checks the PN code information and the signal-to-noise ratio included in the quality information collected in step S103 (S107), and by using this, each PN for each unit field. A representative value of the signal-to-noise ratio of the code is selected (S109). In this case, the signal-to-noise ratio representative value of the PN code may be determined as the median value when there are a plurality of signal-to-noise ratio values.

Thereafter, the PN code sorter 150 sorts the PN codes for each unit field in the order of excellent signal strength by referring to the representative values of the PN codes determined in step S109, and divides the sorted PN codes into serving PNs and active PNs. (S111). Next, referring to the sorting result of step S111, when the unit field includes more than the specified number of serving PNs and active PNs, the unit field is selected as the signal overlap region, and the identifier of the unit field is selected as the signal overlap region DB ( 186) (S113).

By doing so, it is possible to easily grasp the signal overlapping area where multiple handoffs occur due to the signal inflow from the various base stations in a specific area.

On the other hand, after separating the signal overlap region, when the operator requests the service status for the unit field, the map server driver 170 drives the map server 12 (S115), the map information including the unit field It is also possible to transmit the quality measurement information and information on whether or not the signal overlap region to the map server 12 to be displayed on the map (S117). In addition, when the operator requests to display the signal overlap area on the map, the map server driver 170 drives the map server 12 in step S115, and the map of the unit field classified as the signal overlap area in step S117. It is also possible to transmit the information to the map server 12 for display on the map.

As such, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without changing the technical spirit or essential features thereof. Therefore, the above-described embodiments are to be understood as illustrative in all respects and not as restrictive. The scope of the present invention is shown by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.
