2 is a flowchart illustrating a method for updating home zone area information for each mobile station according to an embodiment of the present invention.

The present invention relates to a home zone service method of a mobile communication system, and more particularly, to a method of updating home zone information using subscriber call records.

Currently, each mobile communication service provider is developing various services such as different billing systems by time zone or location in order to acquire more subscribers. Recently, homezone services have been developed. When the home zone service designates a specific address (for example, home, work place, etc.) that the subscriber wants, the home zone service is located within the corresponding distance (hereinafter referred to as the location designated by each of the subscribers) based on the address. For the call of the "home zone zone", the charge is made at a low rate (eg, a landline call).

Meanwhile, in order to provide a home zone service, a corresponding home zone area should be allocated to each subscriber first. In addition, the information on the corresponding home zone area allocated when the subscriber subscribes to the home zone service includes the latitude, longitude, base station classification information, and RTD (Round Trip) generated during the cell planning process at the time of designing the initial mobile communication network. Delay) information can be determined by. Here, the RTD information refers to the time when the radio wave output from the base station arrives at the mobile station and then returns to the base station. In general, the RTD information is a distance concept from the base station to the mobile station. The information generated during the cell planning process is divided into latitude, longitude, base station classification information, sector classification information, RTD MIN, RTD MAX information, which is designated for each board when the area where the mobile communication service is performed is tiled. Hereafter referred to as "zone data").

As described above, the reason why each home zone area is divided into sectors and RTDs and the like is because profitability of a service provider must also be considered. That is, the service provider allocates a subdivided home zone service area to each subscriber and discounts call charges to locations where each subscriber actually talks in the corresponding home zone area designated by each subscriber.

However, since the information generated in the cell planning process, such as zone data, is calculated by simulation results, the accuracy thereof is not so high. Therefore, when providing a home zone service by setting a home zone area for each subscriber based on the above information, complaints from subscribers related to billing are expected because the actual call location of subscribers is not predicted due to the characteristics of a mobile wireless environment.

For example, when a particular subscriber makes a call around his or her designated office or home, the subscriber may expect to be charged for the call, but in fact the charge may be charged. . In addition, even when a plurality of subscribers designate the same home zone area, the locations where the corresponding subscribers actually talk are different, and thus, information on the home zone area generated during the cell planning process should not be equally applied to the subscribers. In other words, the information about the home zone area designated for each subscriber needs to be updated according to the position where the subscriber actually talks.

Accordingly, an object of the present invention is to provide a method for updating home zone information using subscriber call records.

In order to achieve the above object, the present invention provides a method for updating home zone information in a mobile communication system for home zone service, comprising: a first step of inputting a subscriber address; A second process of checking whether there is a presence; a third process of reading latitude / longitude information of two addresses closest to the subscriber address from the home zone database if the subscriber address does not exist in the home zone database; and the read latitude. A fourth process of calculating a latitude / longitude for the subscriber address by performing a proportional algorithm on the / longitude information, and storing the calculated latitude / longitude in the home zone database to update home zone information for the subscriber. It is characterized by consisting of five processes.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, specific matters such as a specific address and the like appear, which are provided to help a more general understanding of the present invention, and the present invention may be practiced without these specific matters. It is self-evident to those who have knowledge. 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.

1 is a diagram illustrating a configuration of a mobile communication system for performing a home zone service according to an exemplary embodiment of the present invention.

A mobile station (MS) 200 is a mobile phone subscribed to a home zone service.

The Mobile Switching Center (hereinafter referred to as MSC) 300 provides a transmit / receive path for exchanging data or control signals with other communication networks such as a public switched telephone network. .

The home location register (HLR) 100 serves to store subscriber information such as terminal information or additional service information.

The home zone region updater 400 delivers home zone data to be updated to the HLR 100. The home zone updater 400 includes a chip number value storage unit 410, a call information storage unit 420, and a subscriber call record information storage unit 430. The chip number value storage unit 410 stores the first chip number value or the second chip number value. The two chip number values are transferred to the call information storage unit 420, and the call information storage unit 420 stores the location where the call is made when the subscriber makes a call. In addition, the call information storage unit 420 analyzes the call log of the subscriber at a predetermined period (for example, once every 30 days) and transmits the call home information to the subscriber call log information storage unit 430 which will be described later. The value assigned during the update is the minimum RTD value (hereinafter referred to as RTD_min) by subtracting the first chip number value from the largest round trip delay (RTD) value in the call information storage unit 420. The maximum RTD value (hereinafter referred to as RTD_max) is obtained by adding the second chip number value.

Table 1 below shows the elements required to manage the home zone of a subscriber and their definitions.

Home-Zone List Number Element Justice hz_unm (1) nsn National switching number nid # 1 Network Identifier (MSC) (1234567) bts # 1 (N = 1) BTS_ID (0) sector # 1 (N = 1) SECTOR_ID (123) rtd_min # 1 (N = 1) RTD_MIN (2) rtd_max # 1 (N = 1) RTD_MAX ㆍ ······ hz_unm (8) nid # 8 (N = 8) BTS_ID bts # 8 (N = 8) BTS_ID sector # 8 (N = 8) SECTOR_ID rtd_min # 8 (N = 8) RTD_MIN rtd_max # 8 (N = 8) RTD_MAX

According to Table 1, when hz_lst () is called a home zone list, one subscriber may have eight such home zone lists.

Table 2 lists the elements for statistic call log by subscriber and explains its definition.

Element Justice nsn Calling subscriber number nid Network Identification (Network Identification) bts_id BTS_ID sector_id SECTOR_ID rtd RTD value by currency cnt Calling & Location Calls hz_num Priority of Home Zone Lists

In Table 2, cnt is a cumulative value of the number of incoming / outgoing or location registration or home zone region information update request calls having the same NSN, NID, BTS_ID, SECTOR_ID, and RTD values. In addition, considering the above-described home zone lists hz_lst (1) to hz_lst (8) of Table 1, hz_num may have a value ranging from priority '1' to '8'. However, when a call is made outside the home zone, the hz-num has a value of '9'. The priority may be determined by signal strength.

The following Table 3 is a table showing the elements and their definitions for specifying the home zone range to be applied to each base station.

Element Justice bts_id Base station device number (BTS_ID) chip_no1 Decrease value to determine RTD minimum value (RTD_min) chip_no2 Value added to determine the RTD maximum (RTD_max)

The chip_no is a field provided to determine the values suitable for the characteristics of each BTS without updating the RTD_min and the RTD_max for each BTS at the time of updating Table 2 described above. Chip_no for each BTS may be manually entered.

Table 4 below shows the call log information received by the LDSPC from the MSC.

Call log number NSN NID BTS_ID SECTOR_ID RTD … One 1234567 0 123 2 42 … 2 1234567 0 123 2 41 … 3 1234567 0 123 2 41 … 4 1234567 0 123 2 40 … 5 1234567 0 123 2 42 … 6 1234567 0 125 One 45 … 7 1234567 0 123 2 42 … 8 1234567 0 125 One 45 … 9 1234567 0 123 2 42 … 10 2345678 0 125 One 43 …

According to Table 4, all call log information of one subscriber is stored. Specifically, nine call log information of the subscriber whose NSN is 1234567 is stored. The home zone updater analyzes the call log information when the number of call log information collected for each subscriber is more than a certain number or when a certain time elapses.

Table 5 below is a table created as a result of processing the call log information of Table 4 based on Table 2 described above.

nsn nid bts_id sector_id rtd cnt hz_num 1234567 0 123 2 42 4 One 1234567 0 123 2 41 2 One 1234567 0 123 2 40 One One 1234567 0 125 One 45 2 9 2345678 0 125 One 43 One 2

Referring to the process in which Table 5 is made from Table 4 in detail as follows.

The home zone area updater 400 reads the information of call record 1 from Table 4 and checks whether the same information is already stored in Table 2 above.

In other words, it checks whether there is call record information with nsn 1234567, nid 0, bts_id 123, sector_id 2 and rtd 40. If the same call record information does not exist as a result of the inspection, a record in which cnt and hz_num are added to the call record information 1 is generated and stored in Table 5. In this case, cnt is 1 and hz_num is 1.

max (cnt) is obtained for nsn, nid, bts_id and sector_id. Here rtd is 42 and cnt is 4. count is 1 because there is one record with cnt 4. As such, when count is 1, rtd at this time is obtained, and RTD_min and RTD_max of the call information storage unit 420 are updated according to the first and second chip number values of the chip_number storage unit 430. If the count is 2 or more, an average of the rtd values at this time is taken and the RTD_min and the RTD_max are updated according to the first and second chip number values. For example, if rtd is 45 and cnt is 4, count is 2. In this case, the average of 42 and 45 is 43.

2 is a flowchart illustrating a method for updating home zone area information for each mobile station according to an embodiment of the present invention.

When the subscriber address is input from the MS 200 in step a, the MSC 300 checks whether the subscriber address exists in the home zone database in step b. If the check result exists, the corresponding latitude / longitude data is output. The above is a known operation.

On the other hand, if the subscriber address does not exist in the home zone database in step b, the process proceeds to step c to read latitude / longitude information of two addresses closest to the subscriber address from the home zone database. In step d, the latitude / longitude of the subscriber address is calculated by performing a proportional algorithm on the read latitude / longitude information. In step e, the calculated latitude / longitude data is output and transmitted to the HLR 100.

Meanwhile, the proportional algorithm consists of the following equations (1) and (2). Assumptions for representing the two equations are as follows. The two nearest addresses are called 263 B-dong and A-69 B-dong, respectively, and the latitude / longitude coordinates corresponding to each are assumed to be (X1, Y1) and (X2, Y2). The address to be obtained is called 265 B-dong in A-gu, and the latitude / longitude coordinates are (X, Y).

As described above, the present invention has the advantage of maintaining the subscriber home zone information more accurately by allowing the initial granted home zone area for each subscriber, and also has the advantage of further increasing the satisfaction of subscribers receiving the home zone service. have.
