Description

Home zone database construction device for home zone service {HOMEZONE DATABASE CONSTRUCTION APPARATUS FOR HOMEZONE SERVICE}

The present invention relates to a mobile communication system, and more particularly, to an apparatus for building a home zone database for home zone service.

The home zone service is to allocate a specific zone (homezone) to the mobile subscriber and apply different pricing schemes when the subscriber calls within the zone and when the outside call is made.

Assuming that there is a subscriber who has applied for home zone service using his or her home as the home zone, the subscriber charges the same rate as a landline call when talking on a mobile phone in his or her home, and the wireless call fee when making a call outside the home. You can implement a home zone service that charges

Accordingly, an object of the present invention is to provide a home zone database construction apparatus for home zone services.

According to an aspect of the present invention, there is provided an apparatus for building a home zone database for home zone service, wherein the cell plan tool generates a coverage map for determining base station coverage and generates zone data for a home zone service using the coverage map. A cell plan processor comprising a conversion unit, a location register for storing subscriber information such as terminal information and additional service information, an address location database for receiving and storing a mobile phone number and a general phone number from a customer care center, and a base station Zone database that receives home phone number and round trip delay from transmitter system, receives zone data from cell plan processor, and creates and stores home zone data for subscriber based on latitude and longitude information provided from address location database Roi It is characterized in that it is composed of a location center and a service center for delivering the home zone data transmitted from the location manager to the affiliated location register or vice versa.

1 is a diagram showing the configuration of a home zone database building apparatus for a home zone service according to an exemplary embodiment of the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, specific details such as specific file types are shown, which are provided to help a more general understanding of the present invention, and the present invention may be practiced without these specific details. It is self-evident to those who have. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

When a subscriber who wants to receive home zone service subscribes to the service, he / she considers several things such as base station location information (latitude / longitude), base station coverage, base station installation status or local information based on the address presented by the subscriber. Set the.

1 is a diagram illustrating a configuration of an apparatus for building a home zone database for a home zone service according to an exemplary embodiment of the present invention.

The cell plan processor 100 includes a cell plan tool 110 for generating a coverage map that determines coverage for each base station, and a converter 120 for generating zone data using the coverage map. . The cell plan tool is software for simulating a propagation environment and may use a known cell plan tool for CDMA.

The home location register (HLR) 400 serves to store subscriber information such as terminal information or additional service information.

Location Determination 100 is composed of an Address Location Data Base (ALDB) 210 and a Zone Data Base (ZDB) 220. The address location database 220 receives a Mobile Indicatin Number (MIN) and a National Significant Number (NSN) from a Customer Care Center (CCC). When the subscriber applies for the home zone service to the customer care center, the subscriber receives a general phone number in addition to the mobile phone number originally possessed by his mobile phone. The general phone number is a phone number for billing for calls made in the home zone area. to be. The billing is divided based on the departure of the home zone area. Thus, two phone numbers are not necessarily used, and can be implemented in various ways.

The zone database 300 is provided with a general telephone number and a round trip delay (RTD) from a base station transceiver subsystem (BTS). In addition, the zone database 300 stores home zone data for each subscriber based on latitude and longitude information provided from the address location database 210.

Service Provisioning Center (SPC) 300 serves to deliver the home zone data transmitted from the location manager 200 to the affiliated location register 400 or vice versa.

When the initial subscriber attempts to access the network, the customer care center receives a list of candidate base stations around the subscriber's home through the zone database 300. To do this, they must have the candidate station information for the terrain bin.

The data file predicted using the cell plan tool is as follows.

site_id, site_char, station_char, signal_val, longitude, latitude

This file is for layer 0 file representing the best server list, layer 1 file for the next (second) best server list, layer 2 file for the next (third) best server list, etc. All eight layers are organized. The eight files are converted into the following format and transmitted to the location determining unit 200. The type of the file is an ASCII file.

LATITUDE | LONGITUDE | SID | NID | BTSID | SECCTOR_ID | MIN_RTD | MAX_RTD | RSSI | E _C / I _O.

For example,

36,0,49.5 | 127,0,1.5 | 1700 | 0 | 0 | 1 | 36 | 39 | -97 | | 1700 | 0 | 2 | 2 | 40 | 44 |. ｜｜｜｜｜｜

The delimiter of each field (fild) uses '|' and if data is null, it is expressed as one blank character. The rank of the candidate is the highest record of the first column in any latitude and longitude, and the lowest of the last eighth column. That is, in one row, the first field is latitude and longitude, and then there are eight consecutive elements of "SID | NID | BTSID | SECTOR_ID | MIN_RTD | MAX_RTD | RSSI | E _C / I _O ". do.

The minimum and maximum RTD calculation is a path of the three-dimensional loss and the height of the terminal (for example, 1.5m) calculated by the height and position of the antenna center line of the base station from the base station DB and the distance from the corresponding empty position. Calculation is done through the McCator projection, where the reference projection mode is WGS84.

RTD (MIN / MAX) = 8 * [INT (2 * LOS / 250) + △ ± a] system chip

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the present invention has an advantage of easily constructing a home zone database that is a basis for accurate home zone service.
