Description

Data Management Method of Visiting Mobile Subscribers in Mobile Communication System

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication system, and in particular, a visit movement in a mobile communication system that searches for, changes, and manages a subscriber number having a different operator number among visited mobile subscribers registered in a visitor location register, which is one of network components of the mobile communication system. It relates to a subscriber data management method.

In general, a mobile communication system is a switching system that enables a mobile terminal (mobile station) to move while communicating with a mobile object. A CDMA (Code Division Multiple Access) method is used, and a digital cellular system or PCS (Personal Communication System).

In such a mobile communication system, a visitor location register (VLR) manages a visitor's location and subscriber's registration information.

Thus, the method for retrieving and changing the subscriber information of the visitor location register is performed by storing the subscriber data information using the visited subscriber's telephone number.

1 is a flowchart illustrating a data area access of a conventional visiting mobile subscriber.

Thus, in the conventional visitor location register, only a phone number having a matching number of NPAs can be stored and managed in one visitor location register. In fact, for one visitor mobile subscriber, the operator number (for example, 011: SK Telecom, 017: New Century Telecom) did not need to be managed separately, so after removing the operator number from the telephone number field, the subscriber's telephone number 8 Only the seats were used to retrieve and manage subscriber information.

That is, under the assumption that all subscribers have the same operator number, if the mobile directory number (MDN) of the visiting mobile subscriber is "011-0890-1284", the operator number (for example, 011) is removed. Access the subscriber data area by using the 8-digit telephone number of the subscriber telephone number with the upper 6 digits ("89012") and the lower 1 digits ("8") as offsets. However, since all the subscriber information is distributed and stored in the processor corresponding to the last number of the telephone number, the index table for the subsequent number "4" after the lower one "8" can be accessed without searching.

As such, all visited mobile subscribers registered in one visitor location register implement a subscriber information database under the condition that the operator numbers match.

However, the visitor mobile subscriber having a different operator number is present in the current visitor location register, but the visitor location register has a problem that cannot be distinguished.

Accordingly, the present invention has been proposed to solve the above-mentioned general problems, and an object of the present invention is to provide a subscriber number having a different operator number among the visited mobile subscribers registered in the visitor location register, which is one of network components of the mobile communication system. The present invention provides a method for managing data of a visiting mobile subscriber in a mobile communication system capable of searching, changing, and managing the data.

In order to achieve the above object, in the mobile communication system according to the present invention, a data management method of a visited mobile subscriber is provided.

A first step of allocating an appropriate accommodation memory area of a subscriber that the visitor location register can accommodate, and setting an index table as a main area table, a sub area table, and a data area; A second step of dividing the subscriber's telephone number into upper six digits and lower two digits and two digits after the first step; A third step of accessing the main area table by using the first 6 digits of the subscriber's telephone number and analyzing whether a subscriber having the same number is already registered in the value of the main area table; A fourth step of searching for the subarea table by setting a second two-digit value of the subscriber's telephone number as an offset after the third step; A fifth step of searching the sub-area table once again by using the third two digits of the subscriber's telephone number after the fourth step; The technical configuration is characterized by performing a sixth step of accessing the data of the subscriber by obtaining the address of the memory where the data of the actual subscriber is stored by searching the subarea table.

<Explanation of symbols for the main parts of the drawings>

1: Main area table 2: Sub area table

3: data area

Hereinafter, with reference to the accompanying drawings an embodiment according to the technical idea of the data management method of the visited mobile subscriber in the present invention as described above in detail.

First, in order to solve the conventional problem, the present invention sets an index area for indicating a data management area as follows. The index area is divided into a main area and a sub area so that subscribers having different service number can search and change in the visitor location register. After dividing 11 digits of subscriber's phone number into 3 parts, refer to the top 6 digits of the number, find key value for accessing main area, access to sub area using next 2 digits, 2 digits, By accessing the data area where subscriber data is stored, subscribers with different operator numbers can store and manage subscriber information in one visitor location register.

2 is a flowchart illustrating access of a data area of a visited mobile subscriber to which the present invention is applied.

So, for example, if the subscriber registration number is "011-0890-1284", all 11 digits of the telephone number are used, and the first six upper digits "11089" including the carrier number and the second lower two digits "1" are used. And the next two digits, "28", to access the subscriber data area to be searched / modified using the telephone number. However, since all the subscriber information is distributed and stored in the processor corresponding to the last number of the telephone number as in the related art, the index table for the last one digit “4” can be accessed without searching.

3 is a flowchart illustrating a data management method of a visiting mobile subscriber in a mobile communication system according to an embodiment of the present invention.

As shown in the drawing, the visitor location register allocates an appropriate accommodation memory area of a subscriber that can be accommodated, and sets an index table as a main area table (1), a sub area table (2), and a data area (3). A first step ST1; A second step (ST2) of dividing the subscriber's telephone number into upper six digits and lower two digits and two digits after the first step; A third step of accessing the main area table 1 using the first 6 digits of the subscriber's phone number and analyzing whether a subscriber having the same number is already registered with the value of the main area table 1; (ST3); A fourth step (ST4) of searching for the subarea table (2) by setting the second two-digit value of the subscriber's telephone number as an offset after the third step; A fifth step (ST5) of searching the sub-area table (2) once again by using the third two digits of the subscriber's telephone number after the fourth step; The search of the subarea table 2 obtains the address of the memory in which the actual subscriber data is stored, and performs a sixth step ST6 of directly accessing the subscriber data.

Therefore, in order to access the data of the visited mobile subscriber, the subscriber location register allocates an appropriate accommodating memory area that can be accommodated, and sets up three index tables to access and manage the data area. This index table is set as the main area table 1, the sub area table 2, and the data area 3.

The subscriber's 11-digit phone number is divided into upper 6 digits and lower 2 digits, respectively, to determine whether subscriber data is registered. Access the first main area table (1) using the top 6 digits of the subscriber's telephone number (11 digits), and analyze whether the subscriber with the same number is already registered in the value of the main area table (1). Search the subarea index table 2 by setting the second two-digit value as an offset, search the subarea index table 2 again using the remaining two digits, and store the actual subscriber data. Obtain the address of the memory and access the subscriber's data directly.

Any subscriber data is stored at any address in the data area, and this address is stored in the area for the corresponding subscriber indication in the index table.

The operation of the present invention will be described in detail in the case of subscriber data insertion.

4 is a flowchart illustrating a method of managing data of a visited mobile subscriber by managing a main region table when inserting data in a mobile communication system according to an embodiment of the present invention, and FIG. 5 is a visited movement by managing a subregion table when inserting data. Flow chart showing how to manage subscriber data.

First, when access to the main area table (1) of the index for inserting the subscriber data, access the main area table (1) of the index using the upper six digits of the subscriber's telephone number, and separates the key value ( ST11). Then, it is checked whether there is tuple information in the main region table (ST12). If there is no tuple information in the main region table, the node accesses the subregion table 2 of the index, requests node allocation, and stores the allocated index value (ST13). If there is tuple information in the main region table 1 or if the allocated index value is stored, the node index region of the allocated sub region table 2 is accessed (ST14).

When access to the subarea table 2 of the index is started, the allocated subarea table index is accessed and moved by the seventh and eighth values of the subscriber's telephone number. Then, a pointer indicating the next subarea table 2 is searched (ST21). Thus, it is searched whether or not there is tuple information in the subarea table 2 (ST22). If there is no tuple information in the subarea table 2, the subarea table 2 is accessed to request node allocation, and the allocated index value is stored (ST23). If there is tuple information in the subregion table 2 or if the allocated index value is stored, the subregion table 2 accesses the node index region of the allocated subregion table 2 to access the next subregion (ST24).

So, we go to the next subarea, access the assigned subarea table index, and move by the 9th and 10th values of the subscriber's telephone number. Then, a pointer indicating the next subarea table 2 is searched (ST25). Thus, the subfield table 2 is searched for whether there is tuple information (ST26). If there is no tuple information in the subarea table 2, the subarea table 2 is accessed to request node assignment and store the assigned index value (ST27). If there is tuple information in the subregion table 2 or if the allocated index value is stored, the node subregion of the allocated subregion table 2 is accessed to access the next subregion (ST28).

Then, it is searched whether or not there is tuple information in the data area 3 (ST29). If there is no tuple information in the data area 3, the subscriber information to be input is stored (ST30). If there is tuple information in the data area 3, the stored error message is output (ST31).

In this way, the subscriber information is stored and the subscriber information is inserted.

Meanwhile, in the case of subscriber data insertion, the operation according to the present invention will be described in detail as follows.

6 is a flowchart illustrating a method of managing data of a visited mobile subscriber by managing a main region table when selecting data in a mobile communication system according to an embodiment of the present invention, and FIG. 7 is a visited movement by managing a subregion table when selecting data. Flow chart showing how to manage subscriber data.

First, when access to the main area table (1) of the index to select the subscriber data, access the main area table (1) of the index by using the upper six digits of the subscriber's telephone number, and separates the key value ( ST41). Then, it is checked whether there is tuple information in the main region table (ST12). If there is no tuple information in the main area table 1, an error message is output as "Tuple Not Found" because the entered subscriber number does not exist (ST43). If there is tuple information in the main region table 1, the node index region of the allocated subregion table 2 is accessed (ST44).

When access to the subarea table 2 of the index is started, the allocated subarea table index is accessed and moved by the seventh and eighth values of the subscriber's telephone number. Then, a pointer indicating the next subarea table 2 is searched (ST51). Therefore, it is searched whether or not there is tuple information in the subarea table 2 (ST52). If there is no tuple information in the subarea table 2, an error message is output as "Tuple Not Found" because the entered subscriber number does not exist (ST53). If there is tuple information in the subregion table 2, the subregion table 2 accesses the node index region of the allocated subregion table 2 to access the next subregion (ST54).

So, we go to the next subarea, access the assigned subarea table index, and move by the 9th and 10th values of the subscriber's telephone number. Then, a pointer indicating the next subarea table 2 is searched (ST55). Therefore, it is searched whether or not there is tuple information in the subarea table 2 (ST56). If there is no tuple information in the subarea table 2, an error message is output as "Tuple Not Found" because the entered subscriber number does not exist (ST57). If there is tuple information in the subregion table 2, the subfield table 2 accesses the node index region of the allocated subregion table 2 to access the next subregion (ST58).

Then, it is searched whether or not there is tuple information in the data area 3 (ST59). If there is no tuple information in the data area 3, an error message is output as "Tuple Not Found" because the entered subscriber number does not exist (ST60). If there is tuple information in the data area 3, the selected subscriber information is output and the success result is output (ST61).

In this way, the subscriber information is selected.

As described above, the present invention can search, change, and manage a subscriber number having a different operator number among the visited mobile subscribers registered in the visitor location register, which is one of the network components of the mobile communication system.

Although the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.

As described above, in the mobile communication system according to the present invention, the data management method of the visited mobile subscriber enables the visitor location register to manage the subscriber even if there are subscribers having different operator numbers. It is effective to manage visitor mobile subscriber data information having a business number of up to 000-999.
