Description

Auxiliary number service method in mobile network {METHOD FOR PROVIDING TWO NUMBER SERVICE IN MIBILE NETWORK}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication network, and more particularly, to an auxiliary number service method in a mobile communication network which assigns an auxiliary number to a called terminal.

With the development of communication technology, mobile communication technology that can communicate while the terminal is moving has been developed and used. In such a mobile communication network, unique numbers are assigned to terminals, and are configured to call terminals using this number.

On the other hand, according to the development of the mobile communication network, a two-number service method for giving two numbers to one terminal has been developed and put into practical use. In this method, a terminal can be used as two terminals by giving an auxiliary number in addition to one main number. The conventional 2 number service method has the advantage that the terminal itself can recognize the major number and the minor number, so that a separate address translation (translating the secondary number to the major number) is not necessary in the mobile communication network. There is a problem that the configuration is complicated. That is, as described above, the terminal needs to recognize an auxiliary number in addition to the main number, and thus, the configuration of the terminal becomes complicated and accordingly, a production cost of the terminal increases.

In addition, in the conventional method, since the terminal must recognize the auxiliary number, there is a disadvantage in that a plurality of auxiliary numbers cannot be assigned to the terminal. That is, in order to allocate a plurality of auxiliary numbers other than the main number to the terminal, the terminal must recognize all of the assigned auxiliary numbers. For this purpose, since the configuration of the terminal is complicated, there is a problem that there is no practicality.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to provide an auxiliary number service method that can easily provide an auxiliary number service by configuring a mobile communication network to recognize a major number using an auxiliary number. .

In order to achieve the above object, the present invention provides an auxiliary number service method of a mobile communication network, comprising the steps of: providing a call establishment request message provided from a calling terminal to a mobile communication switch; Providing a home number register with a supplemental number and a called location request message provided from the mobile communication switch when the called party number included in the call establishment request message is a supplemental number; Providing the mobile communication switch with a major number and a ring tone code corresponding to an auxiliary number detected and provided at a home location register; And providing a ringing code and an incoming request from a mobile communication switch to a terminal having a main number, causing the main number terminal to output a ring tone corresponding to the ring tone code.

MS: terminal BS: base station

MSC: Mobile Switching System HLR: Home Location Register

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

1 shows an example of a communication network, where MS means a mobile station, and a subscriber can wirelessly connect to a network using the MS. BTS is a mediation between the MS and the Mobile Switch Center (hereinafter referred to as MSC), and is composed of a BTS (Base Tranceiver System) and a BSC (Base Station Controller). One or more transceivers located in the field to perform wireless communication with the MS A BSC is a device for controlling BTSs that exchanges messages with BTSs and MSCs. Do.

MSC refers to an automated system that interfaces user communications from a wireless network to a wired or wireless network.

The Home Location Register (hereinafter referred to as HLR) refers to a functional device that manages mobile subscribers by storing subscriber information (eg, electronic serial number, user file, current location). The HLR can be located integrated with the MSC or located independently, and can serve multiple MSCs as a single HLR.

In the present invention, a plurality of tables as shown in FIG. 2 are configured in the HLR, in which major numbers corresponding to auxiliary numbers of the terminal MS are stored. In this embodiment, 100 tables are configured, and the tables are assigned with table numbers 01-99, respectively. Table 01-99 is assigned a table address of 4 (0000-9999) digits. In the present invention, an auxiliary number is allocated using the above-described table structure. That is, the system of the auxiliary number proposed in the present invention has a system of AAA-XX-YYYY. Here, AAA means an arbitrary number indicating that it is an auxiliary number, XX means a table number (00-99), and YYYY means a table number (0000-9999). Therefore, in the embodiment of FIG. 2, it will be readily apparent to those skilled in the art that service for 1,000,000 supplemental numbers is possible.

In addition, in each address (0000-9999) of the table (00-99) of the present invention, main number information and code information may be further stored, and the code information may correspond to call signals as described later. It means ring tone code to designate ring tone. This ring code may be designated by the subscriber who subscribed to the supplemental number service.

The call setup process in the apparatus having the above-described configuration is shown in FIG. Hereinafter, the process of the terminal MS_A calls the terminal MS_B using the assistance number for the terminal MS_B. Here, it is assumed that the terminal MS_A is in the BSC_A network, and the terminal MS_B is in the BSC_B network.

When the terminal MS_A transmits a signal of a set up request signal including an auxiliary number of the terminal MS_B, that is, AAA-XX-YYYY, the call setup request signal is provided to the MSC by BSC_A.

The MSC detects that the called number is an auxiliary number through the AAA number in the called number in the call setup request signal from the BSC_A, and provides the called location request message to the HLR along with the called number.

The HLR searches for a major number corresponding to a supplemental number (XX-YYYY) included in the called location request message, and provides the MSC with location information, major number information, and ring code information of the major number terminal. Here, the HLR searches the table (00-99) for the major number corresponding to the minor number (XX-YYYY), and the number (0000-9999) corresponding to the YYYY of the retrieved table. It is obtained by reading.

The MSC provides the main number and the ringtone code to the corresponding BSC_B according to the location information, and the BSC_B that has obtained the main number information and the ringtone code information can provide the incoming request and the predetermined ringtone code to the destination terminal MS_B having the main number. have.

The called terminal MS_B outputs a predetermined ring tone according to the incoming request from the BSC_B. However, since the ring tone is based on the ring tone code from the BSC_B, the user of the called terminal MS_B can easily determine that the incoming call is by an auxiliary number. Able to know.

As described above, in the present invention, by using the tables in the HLR, the auxiliary number is converted into the main number, thereby making an incoming request to the terminal of the main number, thereby providing an auxiliary number service without changing the configuration of the terminal. Can provide.

In addition, in the present invention, since the user can determine the ring tone type for each auxiliary number, there is an effect that it is easy to know which auxiliary number is called by the ring tone.
