2 is a block diagram illustrating a configuration of a home location register (HLR) according to the present invention.

Referring to FIG. 2, the home location register (HLR) 300 according to the present invention is for managing subscriber information. In the present embodiment, the HLR 300 displays a subscriber number (MIN) and a number extension. A number extension database 310 for managing flag FLAG information is included.

The number extension database 310 provided in the HLR 300 includes a MIN which is a subscriber number and a number extension flag FLAG indicating whether the number of the MIN is extended. In the database of the HLR, the MIN is managed as an extension number. When a terminal having a three-digit station number, for example, 011-7xx-xxxx, that is a number before expansion is registered, the MIN is an extension number. For example, recognizing that it is 011-7xx-xxxx, the FLAG is 'ON'.

In addition, if the terminal having a 4-digit station number that is an extension number, for example, 011-77xx-xxxx, performs location registration, the FLAG recognizes that the MIN is an extension number, for example, 011-77xx-xxxx, and the FLAG is 'OFF'. It becomes a state.

3 is a flowchart illustrating a first embodiment of a method of receiving a short message according to the present invention. The first embodiment relates to short message transmission and reception when the called terminal has a previous extension number, that is, a three-digit station number.

Referring to FIG. 3, the called terminal 210 performs location registration (S11). In this case, the called terminal 210 has a three-digit station number, for example, 011-7xx-xxxx, which is a number before extension, and receives information including [MIN = 011-7xx-xxxx] for location registration. This is transmitted to the MSC 240 of the called party via the exchange to which it belongs, that is, the BTS 220 and the BSC 230 of the called party system 200 of the present embodiment.

Accordingly, the MSC 240 notifies the HLR 300 of the registration information [MIN = 011-7xx-xxxx] of the called terminal 210 (S12). Since the HLR 300 [MIN = 011-7xx-xxxx] notified from the MSC 240 is the number before the expansion, the HLR 300 is one of 011-77xx-xxxx subscriber information existing in the number expansion database 310. Turn FLAG, the number extension flag, on. [MDN = 011-77xx-xxxx] is transmitted to the MSC 240 of the called party as a registration response (S13).

On the other hand, the calling terminal 110 transmits a short message to the called terminal 210, the user of the calling terminal 110 is exactly whether the number of the called terminal 210 is the extension number or extension number before Since it is not recognized, it is possible to send a short message using an extension previous number or an extension number, for example, 011-7xx-xxxx or 011-77xx-xxxx as a called number (S20).

Accordingly, the MSC 140 of the calling party system 100 sends a short message to the MMC using the extension previous number or extension number, for example, 011-7xx-xxxx or 011-77xx-xxxx, as the MIN. Transfer to (S30). The SMC 400 transmits the received called number as it is to the HLR 300 and performs the location request of the called terminal 210.

The HLR 300 retrieves information of 011-77xx-xxxx from the number extension database 310 when the called number according to the request of the SMC 400 is an extension number . At this time, when the called number is 011-7xx-xxxx, which is the extension previous number, the HLR 300 searches the number extension database 310 by converting the called number into an extension number 011-77xx-xxxx.

The HLR 300 may recognize that the state of the called terminal 210 is the number before expansion, that is, FLAG is turned on according to the search result of the number extension database 310. That is, since FLAG is turned on for the current MIN of the called terminal corresponding to the extension previous number or extension number requested by the calling terminal 110, for example, 011-7xx-xxxx or 011-77xx-xxxx, the called terminal is currently present. The number can be seen that the extension number 011-7xx-xxxx.

Accordingly, the HLR 300 responds to the SMC 400 with information [011-7xx-xxxx] of the called terminal 210 (S50).

The SMC 400 transmits a short message to the MSC 240 of the called party, to which the called terminal 210 belongs, according to the response of the HLR 300 as [MIN = 011-7xx-xxxx] (S61). . The MSC 240 transmits the short message received from the SMC 400 to the called terminal 210 (S62).

In this case, the called terminal 210 has a 4-digit station number, for example, 011-77xx-xxxx, which is a number before expansion, and receives information including [MIN = 011-77xx-xxxx] for location registration. This is transmitted to the MSC 240 of the called party via the exchange to which it belongs, that is, the BTS 220 and the BSC 230 of the called party system 200 of the present embodiment.

Accordingly, the MSC 240 notifies the HLR 300 of the registration information [MIN = 011-77xx-xxxx] of the called terminal 210 (S112). Since the HLR 300 [MIN = 011-77xx-xxxx] advertised from the MSC 240 is the number before the expansion, the HLR 300 is one of 011-77xx-xxxx subscriber information existing in the extension database 310. Turn off FLAG, the number extension flag. [MDN = 011-77xx-xxxx] is transmitted to the MSC 240 of the called party as a registration response (S113).

On the other hand, the calling terminal 110 transmits a short message to the called terminal 210, the user of the calling terminal 110 is exactly whether the number of the called terminal 210 is the extension number or extension number before Since it is not recognized, the short message can be sent using the extension previous number or the extension number, for example, 011-7xx-xxxx or 011-77xx-xxxx as the called number (S120).

Accordingly, the MSC 140 of the calling party system 100 sends a short message to the MMC with the extension previous number or extension number, for example, 011-7xx-xxxx or 011-77xx-xxxx, as the MIN. Transfer to (S130). The SMC 400 sets the received information to MIN as it is and makes a location request for the called terminal 210 to the HLR 300 (S140).

The HLR 300 retrieves the information of the 011-77xx-xxxx from the number extension database 310 at the request of the SMC 400. At this time, the HLR 300 can know that the state of the called terminal 210 is an extension number, that is, FLAG is OFF. That is, the current MIN of the called terminal corresponding to the extension previous number or extension number requested by the calling terminal 110, for example, 011-7xx-xxxx or 011-77xx-xxxx, is an extension number, for example, 011-77xx-xxxx. You can see that.

Accordingly, the HLR 300 responds to the SMC 400 with information [011-77xx-xxxx] of the called terminal 210 (S150).

The SMC 400 transmits a short message to the MSC 240 of the called party, to which the called terminal 210 belongs, according to the response of the HLR 300 as [MIN = 011-77xx-xxxx] (S161). . The MSC 240 transmits the short message received from the SMC 400 to the called terminal 210 (S162).

After receiving the short message, the called terminal 210 transmits a response thereto according to the MSC 240 (S171), and the MSC 240 transmits the response to the SMC 400 (S172). According to the response of step S72, the SMC 400 transmits the response according to the success of the short message transmission to the MSC 140 of the calling party (S181), and the MSC 140 transmits the response to the calling terminal 110. (S182).

Referring to FIG. 5, the called terminal 210 performs location registration (S211). In this case, the called terminal 210 has a three-digit station number, for example, 011-7xx-xxxx, or an extension number, for example, 011-77xx-xxxx, which is a number before extension, and [MIN = 011-7xx for location registration. -xxxx] or [MIN = 011-77xx-xxxx] to the BTS 220 and the BSC 230 of the exchange to which the destination terminal 210 belongs, that is, the destination system 200 of the present embodiment. It transmits to MSC 240 of a called party via.

Accordingly, the MSC 240 notifies the HLR 300 of the registration information of the called terminal 210 (S212). The HLR 300 registers the registration information notified from the MSC 240 to the number extension database 310 by the above-described method, and transmits the registration response to the MSC 240 of the called party (S213).

On the other hand, the calling terminal 110 transmits a short message to the called terminal 210, the user of the calling terminal 110 is exactly whether the number of the called terminal 210 is the extension number or extension number before Since it is not recognized, a short message can be sent using 011-7xx-xxxx or 011-77xx-xxxx as the called number (S220). At this time, the subscriber number of the calling terminal 110 is an extension previous number, for example, 011-7xx-xxxx, or an extension number, for example, 011-77xx-xxxx.

The MSC 140 of the calling party system 100 receives the called information (011-7xx-xxxx or 011-77xx-xxxx) as MIN and the subscriber's subscriber number (011-7xx-xxxx or 011-77xx). A short message including a form of -xxxx) is transmitted to the SMC 400 (S230). The SMC 400 inquires the location of the called terminal 210 to the HLR 300 as received call number (S240).

The HLR 300 retrieves the information of the called number from the number extension database 310 at the request of the SMC 400. The HLR 300 then responds with the result to the SMC 400 (S250).

The SMC 400 sets a call back number according to the type of the calling party number of the calling terminal, sets the called number as the MIN according to the response of the HLR 300, and sends a short message including the reply number. The receiver terminal 210 transmits to the MSC 240 of the called party to which it belongs (S260). The SMC 400 uses the number as a reply number when the calling number is an extension number, that is, 011-77xx-xxxx. However, if the calling number is in the form of the extension number, that is, 011-7xx-xxxx, the reply number is set by changing the reply number to the extension number, for example, 011-77xx-xxxx.

The MSC 240 transmits the short message received from the SMC 400 to the called terminal 210 (S270). Accordingly, the extension terminal of the calling terminal 110 is displayed as a reply number in the called terminal 210.
