Description

System and method for call process of duplex number service subscriber in FNPS}

The present invention relates to a system and a method for simplifying a call processing procedure of a dual number subscriber in a flexible number routing and number portability server (hereinafter referred to as FNPS), and more particularly, to an international device assigned to a terminal in an FNPS. By managing a DB (main number-01X, minor number-010) for a mobile station identification number (International Mobile Station Identity, hereinafter referred to as IMSI) through DB, it is possible to immediately manage the major number even when an incoming call to the minor number is attempted. A system and method for simplifying a call processing procedure by sending a location request message (LOR) to a Home Location Register (hereinafter referred to as HLR).

Since January 1, 2004, Mobile Number Portability (MNP) has been implemented to maintain existing mobile phone numbers even if the service provider is changed. In addition, efforts have been made by the Ministry of Information and Communication and each mobile carrier to convert existing carrier identification numbers (011, 016, 017, 018 and 019, hereinafter 01X) of mobile phone numbers into an integrated carrier identification number (010). .

As a policy, all new subscriptions and phone numbers are changed after the MNP is mandatory, and an integrated carrier identification number '010' is assigned. Currently, each mobile carrier promotes the transition from '01X' to '010'. In order to switch to Code Division Multiple Access (CDMA) subscribers to Wideband Code Division Multiple Access (WCDMA), a '010X' subscriber is provided with a separate '010'. By 'numbering', voice, video (3G), short message service (hereinafter referred to as SMS) and multimedia service (hereinafter referred to as MMS) can all be called by the '01X' number. To provide services.

As described above, a conventional call processing procedure for a subscriber (hereinafter referred to as a 'double-number subscriber') that has changed from CDMA to WCDMA and owns a '01X' number and a '010' number is as shown in FIG. .

1 is a flowchart illustrating a conventional call processing procedure for a dual number subscriber.

For reference, '01X' number is referred to as' main number ',' 010 'number as' minor number', '016-123-4567' is used as an embodiment of the main number, and '010 as an embodiment of the minor number. -1234-5678 '.

First, when an incoming call is attempted to the sub-number '010-1234-5678', the mobile switching center (hereinafter referred to as MSC) 110 is connected to the sub-number '010-1234-5678' through the FNPS 120. An incoming call is attempted (S101).

After S101, the FNPS 120 transmits a location request message (LOR) and an incoming information request message (SRI) to the HLR 130 in which the sub-number '010-1234-5678' is accepted (S102).

After S102, in the HLR 130 in which the minor number '010-1234-5678' is accommodated, the existence of the minor number in the subscriber DB is checked, and the major number information mapped to the minor number, that is, the major number is '016' The information on the HLR containing '123-4567' and the main number '016-123-4567' is transmitted to the MSC 110 together with the response message (LOR Ack) for the location request message (S103).

After S103, the MSC 110 transmits a location request message (LOR) and an incoming information request message (SRI) to the HRL 140 containing the main number '016-123-4567' with reference to the received main number information (SRI). S104), the HRL 140 accommodated with the major number '016-123-4567' receives a response message (LOR Ack) for the location request message (LOR) and a response message (SRI Ack) for the incoming information request message (SRI). The procedure proceeds after the incoming call processing by transmitting to the MSC 110 (S105).

In the conventional call processing method as described above, when an incoming call voice, video (3G), SMS and MMS is attempted as a minor number, the HLR 130 in which the minor number is accommodated in the MSC 110 and the HLR in which the major number is received (140) There is a problem in that the traffic generation is doubled by sending the location request message (LOR) and the incoming information request message (SRI) to both, and the call setup waiting time is increased by the subscriber.

The present invention simplifies the call processing procedure by integrating and managing the major and minor number information having one IMSI in the FNPS, and sending a location request message (LOR) to the HLR, which has received the major number even when an incoming call is attempted to the minor number. Its purpose is to.

2 is a diagram illustrating a configuration of a system for simplifying a call processing procedure of a dual number subscriber in FNPS according to an embodiment of the present invention.

A system 200 for simplifying a call processing procedure of a dual number subscriber in FNPS according to an embodiment of the present invention is located between a subscriber's mobile communication terminal 210, a mobile communication terminal 210, and a base station controller. A base transceiver station (hereinafter referred to as a BST) 220 for converting a signal format to be suitable for a wired link, a base station controller (hereinafter referred to as a BSC) 230 for managing and controlling a base station; MSC (240) for transmitting the location request message and the incoming information request message without distinction of the carrier identification number of the incoming mobile phone number, DB containing recorded minor number information and main number information mapped to the minor number; And the FNPS 250 for transmitting the location request message and the incoming information request message to any one of a home location register with a minor number and a home location register with a major number. HLR 260 that receives the request message and the called information request message and provides location information for the called mobile phone number.

For reference, a number having any one of 011, 016, 017, 018, and 019 (hereinafter referred to as 01X) of a business identification number is referred to as a 'major number' and a '010' number. .

Hereinafter, the configuration of the system 200 described above will be described in more detail.

The mobile communication terminal 210 is generally a cellular phone, a personal digital assistant (PDA), a personal communication services phone (PCS), an IMT-2000 terminal (International Mobile Telecommunication-2000). ), Such as a Global System For Mobile Communication (GSM) terminal, and the like, which includes a device that provides a communication function for making a call or exchanging data while moving.

The BTS 220 performs a wireless modem function consisting of an antenna and a transmission / reception modem.

For reference, a channel from the mobile communication terminal 210 to the BTS 220 is called an uplink channel or a reverse channel, and a channel from the BTS 220 to the mobile communication terminal 210 is called a downlink channel or a forward channel.

In the present invention, a case in which a channel is connected to a BTS 220 from a mobile communication terminal 210, that is, an uplink channel, is connected and transmitted and received.

The BSC 230 instructs the BTS 220 to allocate a radio channel to the mobile communication terminal 210 with 10 to 40 BTSs 220 and controls the transmission output of the mobile communication terminal 210. .

And it is a kind of small exchange that connects the voice communication path between the mobile communication terminal 210 connected to the BTS 220, and supports the handover to the mobile communication terminal 210 moving between the BTS (220).

Also, the BSC 230 may identify a location area identifier (LAI), which is a unique location area identifier assigned to each BSC 230, so that the mobile communication terminal 210 may know which location area it is. For the purpose of periodically broadcasting, the configuration of the BTS 220 and the BSC 230 is referred to as one base station subsystem (BSS).

The MSC 240 is a type of telephone exchange having several BSCs 230 and providing a connection with an external landline or a mobile communication terminal elsewhere.

Of course, compared with a general telephone, since the mobility of the terminal must be supported, a function of transmitting a paging message for searching for a receiving terminal is added.

In the present invention, the MSC 240 transmits the location request message and the incoming information request message to the FNPS 250 without distinguishing the operator identification number of the incoming mobile phone number received from the mobile communication terminal 210.

For reference, it is assumed that the MSC 240 of the present invention performs both the function of the originating MSC and the destination MSC.

Conventional MSC, as mentioned in the prior art, distinguishes the operator identification number of the incoming mobile phone number received from the mobile communication terminal 210 ('01X' and '010') so that the incoming mobile phone number is' In case of the minor number beginning with 010 ', a location request message and an incoming information request message are transmitted to the HLR or directly to the HLR through the FNPS.

Meanwhile, the FNPS 250 receives a location request message (LOR) and an incoming information request message (SRI) for finding the location and the path of the called mobile phone number and the called mobile phone number from the MSC 240.

If the incoming mobile phone number received by the FNPS 250 is a minor number, the FNPS 250 searches for a major number mapped to the minor number, and requests a location request message and incoming information from the HLR 260 that has received the major number. Send a message.

If the received mobile phone number is the main number, the FNPS 250 directly transmits a location request message and an incoming information request message to the HLR 260 having the main number.

To this end, the FNPS 250 according to an embodiment of the present invention includes a DB recorded a minor number and a major number mapped to the minor number, and manages the major number and minor number, and the MDN and MSISDN. The minor number and major number have the same IMSI.

That is, the major number '016-123-4567' according to the embodiment of the present invention is mapped to the minor number '010-1234-5678' and stored in the DB of the FNPS 250 described above.

For reference, the location request message according to the present invention uses a Location Request Message (LOR) defined by the Wideband Code Division Multiple Access (WCDMA), and the incoming information request message is defined by the Wideband Code Division Multiple Access (WCDMA). Use Send Routing Information (SRI).

HLR 260 is fixed information such as phone number (MSISDN), IMSI, personal information, service type, terminal identification number (IMEI), authentication information of the terminal and the current dynamic location information (VLR address of the current location, Server that stores the exchange address, etc.) This location register may be installed at the exchange or may be installed separately.

For reference, the HLR 260 described below is an HLR in which a main number is accommodated.

3 is a flowchart illustrating a process of simplifying a call processing procedure of a dual number subscriber in FNPS according to an embodiment of the present invention.

For convenience of explanation, it will be described with reference to the components of the system shown in Figure 2, using the '016-123-4567' as the embodiment of the major number, '010-1234-5678' as an embodiment of the minor number To use.

In addition, it is assumed that an incoming mobile telephone number (part number '010-1234-5678') sent from the mobile communication terminal 210 is attempted at the MSC 240 via the BTS 220 and the BSC 230. .

First, the MSC 240 transmits the location request message and the incoming information request message to the FNPS 250 without distinguishing the operator identification number of the incoming mobile phone number (S301).

After S301, the FNPS 250 refers to the operator identification number of the incoming mobile phone number, and determines whether the incoming mobile phone number is one of a minor number and a main number (S302).

As a result of the determination, since the incoming mobile phone number is the sub-number '010-1234-5678', the FNPS 250 searches the main number mapped to the sub-number '010-1234-5678' in its DB, and the main number is' 016-123-4567 '(S303).

 After S304, the FNPS 250 transmits a location request message (LOR) and an incoming information request message (SRI) to the HLR 260 in which the main number is accepted (S304).

For reference, the location request message according to the present invention uses a Location Request Message (LOR) defined by the Wideband Code Division Multiple Access (WCDMA), and the incoming information request message is defined by the Wideband Code Division Multiple Access (WCDMA). Use Send Routing Information (SRI).

After S304, the HLR 260 accommodating the major number transmits a response message (LOR Ack) for the location request message (LOR) and a response message (SRI Ack) for the incoming information request message (SRI) to the MSC 240. An incoming call processing procedure is made (S305).

At this time, the HLR 260 accommodating the major number transmits a temporary local directory number (hereinafter referred to as TLDN) and a mobile station roaming number (hereinafter referred to as MSRN). The local TLDN is a temporary call routing number for call delivery in a mobile telephone exchange. If the terminal is located at another exchange outside of the home switching center, it is a telephone number temporarily assigned by another switching station for call routing. MSRN is a roaming number used for location update and call routing of mobile station, and is a phone number assigned by MSC for VLR call routing when location update request for roaming. The HLR of the terminal can reuse the old MSRN by sending call control parameters to the new VLR and sending a cancellation message to the old VLR. This is later translated into a temporary mobile subscriber identification number (TMSI) and sent to the mobile station.

Although embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical spirit or essential features thereof. You will understand that. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive.
