Abstract

PURPOSE: A member decentralizing method of a visitor location resister is provided to prevent an overload situation when the visitor location registering processor is reworked. CONSTITUTION: The member decentralizing method of a visitor location resister comprises the steps of: deciding how many ciphers of the member's number delivered from a terminal are managed; accessing a database for routing the visitor location register by the decided cipher as a key value; and getting the visitor location registering processor by the database access.

Description

Subscriber Distribution Method in Visitor Location Registration System

The present invention relates to a method for distributing subscribers in a visitor location register system (VLR). In particular, the roaming subscribers in a mobile switching center (MSC) are distributed to the visitor location registration system for efficient management. It is about how to.

1 is a diagram illustrating a table used in a conventional subscriber distribution method. The table R_LR_PFX_TBL of FIG. 1 is a database (DB) which manages a station number assigned to the visitor location registration system, and is composed of the following fields.

The R_LR_PFX_NO field is a station number managed by the visitor location registration system, and the D_LR_NO field represents a number of the visitor location registration system corresponding to the station number. The location register processor (LRP) of the mobile switching center is 10 digits for personal communication services (PCS), and assigns 0 to 9 to each corresponding station number. The D_SPC_NO field indicates signal point information for routing, and the D_LR_GTS field indicates GT information required for exchange with a Home Location Register (HLR). The D_GTS_LTH field indicates the length of the GT information, and the D_HLR_NO field is a domain indicating the number of the subscriber location registration system. Finally, the D_LR_PFX_TYPE field specifies the type of station number.

In the related art, as illustrated in FIG. 1, D_LR_NO is designated for each R_LR_PFX_NO in R_LR_PFX_TBL and managed by the corresponding location registration processor for each LR_PFX.

Therefore, when managing a plurality of LR_PFX in one location registration processor, due to the large number of LR_PFX_TBL used, it is necessary to change the excessive amount of duplicate data when recovering the location registration processor, causing a duplicate database inconsistency. This causes a problem that increases the load on the processor and cannot support even the general functions of the system.

Accordingly, the present invention was devised to solve the above problems, and provides a method for distributing subscribers in a visitor location registration system to solve an overload phenomenon caused by updating a large amount of redundant data when restarting the location registration processor. It aims to do it.

The above and other objects and novel features of the present invention will become more apparent from the following detailed description of the invention and the accompanying drawings.

1 shows a table used in the existing subscriber distribution method applied to the present invention.

2 shows a table used in the subscriber distribution method according to the present invention.

3 shows a table used to determine how many digits of the subscriber number to be managed.

In order to achieve the above object, a preferred embodiment of the subscriber distribution method in the visitor location registration system according to the present invention,

Determining how many digits to manage the last digit of the subscriber number transmitted from the terminal;

Accessing a database for routing the location registration system using the number of digits determined in the above step as a key value;

Obtaining a corresponding location registration processor by accessing the database; And

And managing the subscriber corresponding to the location registration processor.

In the present embodiment, the determination of how many digits of the subscriber number transmitted from the terminal is to be managed is preferably determined according to the location registration mode index (lr_mod_index) value,

The database for routing the location registration system,

A field indicating up to how many digits the terminal of the subscriber number transmitted from the terminal is managed;

A field indicating a state of allocation of a number of a system corresponding to a station number managed by a visitor location registration system; And

It is preferable to have a field indicating the number of the system corresponding to the station number managed by the visitor location registration system,

If the corresponding location registration processor is down, it is preferable to further include the step of selectively changing the location registration processor to continue the service.

The present invention provides a subscriber by introducing a new table called R_LR_ROUT_TBL, which is a database required for routing the visitor location registration system, using a duplicate data called R_LR_PFX_TBL, a database that manages the station number assigned to the visitor location registration system. By designating and managing the location registration processor by comparing the last digit of the number, the overload phenomenon caused by updating a large amount of redundant data when the location registration processor is restarted is solved.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In order to extract and distribute the end of the subscriber number, a table called R_LR_ROUT_TBL is separately set as shown in FIG. 2 is a diagram illustrating a table used in a subscriber distribution method according to the present invention.

The management method by contrasting the table R_LR_ROUT_TBL and the subscriber end is as follows.

First, up to 1, 2, and 4 are managed by lr_mod_index to manage how many digits of the end of subscriber number, and Equation 1 is needed to find D_L_DIGIT of R_LR_ROUT_TBL.

If lr_mod_index = 2, lrp_max_no (max-1)

D_L_DIGIT = hi (9th and 10th of MIN) MOD lrp_max_no + 1

Therefore, as shown in Equation 1, D_L_DIGIT = x is checked and assigned, and if D_LR_NO is assigned to y, the subscriber is managed by location registration processor y. That is, the location registration processor y manages all subscribers whose subscriber numbers end in hi.

Location registration occurs when a subscriber roams to a mobile switching system. At this time, the location registration processor determines the location registration. Therefore, by extracting the last digit from the subscriber number transmitted from the terminal, obtain D_L_DIGIT as described above, and use the value as the key to access the R_LR_ROUT_TBL to obtain the location registration processor, and then manage the subscriber.

In addition, when the location registration processor is down, the system is operated more efficiently by changing the location registration processor at the discretion of the operator.

While the invention is susceptible to various modifications and alternative forms, the disclosure thereof has been described with reference to specific embodiments only. It is to be understood, however, that the present invention is not limited to the specific forms referred to in the specification, but rather that the invention is intended to cover all modifications, equivalents, and substitutions within the spirit and scope of the invention as defined by the appended claims. It should be understood to include.

In the present application operating as described above, the effects obtained by the representative ones of the disclosed inventions will be briefly described as follows.

By designating and managing the location registration processor by matching the last digit of the subscriber number, the system can be operated efficiently and the process can be improved.
