An apparatus and method for providing speed dialing in a mobile communication network according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

1 is a flowchart illustrating an example of a flow of a method for providing speed dialing in a mobile communication network implemented by the present invention.

In a general mobile communication network, the location registration step of a cellular phone proceeds as follows.

First, when the power of the cellular phone terminal is turned on, a message including MIN (Mobile Identification Number or Phone Number) and ESN (Electronic Serial Number) information is sent to the base station, and the base station sends the message to the mobile communication switching center.

Next, the mobile telecommunication switching center compares the received MIN with all MINs in the communication network to determine whether the subscriber station is a subscriber or a visiting subscriber of the home mobile telecommunication switching center. At this time, the home location register (HLR) requests the subscriber's profile.

If the subscriber is a visiting subscriber, the mobile switching center sends a message through the signaling network to the home location register to which the subscriber belongs using routing information stored in a signaling transfer point (STP).

When the home location register of the visiting subscriber's home exchange receives this message, the validity of the number is verified using the MIN and ESN, and the subscriber's location information is stored in the home location register and the subscriber's profile is sent to the visiting mobile switching center. send.

Once this message is received by the visiting mobile switching center, it is stored in the visitor location register (VLR) so that the subscriber can make a call through the visiting mobile switching center without having to go through the home mobile switching center during his stay. .

In addition, when the subscriber is away from the home switching center, that is, while roaming, the steps of call forwarding are as follows.

First, when a specific counterpart dials the subscriber's telephone number, the call is routed to the subscriber's home mobile telecommunication switching center, which requests the caller information of the terminal to the home location register. In this case, the home location register informs that the terminal is in the service area of the other mobile switching center.

The home location register requests the visiting mobile telecommunication switching center to assign a Temporary Local Directory Number (TLDN) for call routing through a signaling network.

The visiting mobile communication switching center transmits the temporary area directory number to the home location register, which transmits it back to the home mobile communication switching center to enable call routing.

When a visiting mobile telecommunication switching center receives a call requested by this temporary area directory number, it transmits a paging signal and forwards the call as with other terminals in the service area.

Meanwhile, in FIG. 1, when the calling terminal 10 dials to the called terminal 15 belonging to the same group, the calling terminal dials only the speed dial number of the called terminal 15 determined according to a preset rule. . This shortcut number may be combined with a special symbol such as an asterisk (*) or a shop (#), as determined.

When the speed dial number of the called terminal 15 is dialed from the calling terminal 10, the calling party mobile communication switching station 11 calls the calling terminal 10 a speed dial number providing service in a group subscriber (hereinafter referred to as "shortcut number service"). The caller information is requested to the condition originating party's home location register (12) (100).

The calling home location register 12 returns a response message to the request of the calling mobile communication switching center 11 (110). The response message combines the called party number 15 corresponding to the called party number within the group by combining the called party number and the corresponding routing number (RN: Routing Number). Make it searchable.

In this case, different routing numbers (RNs) are assigned to different groups in order to prevent duplication of call connections to destination terminals having the same short number.

Therefore, in order to implement the method for providing speed dialing in the mobile communication network according to the present invention, the calling party's home location register 12 allocates a routing number (RN) for the group to which the calling party belongs to the subscriber number of the calling terminal. It will include.

3 is a diagram illustrating an example of a speed dial number management database table in a home location register in a system and a method for providing speed dialing in a mobile communication network according to the present invention.

As described above, it can be seen that a routing table corresponds to one-to-one correspondence for each originating subscriber number.

In this case, the routing number does not necessarily have to be four digits, and may be appropriately assigned by adding or subtracting digits in consideration of characteristics such as the size of the calling subscriber.

On the other hand, when the calling mobile communication switching station 11 receives a response message for the caller information request from the calling home location register 12 (110), the calling mobile communication switching station 11 is called party intelligent network switching station (13) In step 120, an initial address message (IAM) is transmitted. In this case, the called number of the called terminal included in the initial address message is formed by adding the routing number and the shortcut number of the called terminal in the same manner as in the response message received from the calling home location register 12.

The receiving side intelligent network switching center 13 sends a request number analysis request for the initial address message to the service control point (SCP) 14 when the initial address message is received from the calling mobile communication switching center 14. Transmit (130). The information provided from the called party's intelligent network switching station 13 to the service control point 14 in the process of transmitting the called party number analysis request is the routing number information included in the initial address message received from the calling mobile telecommunication switching station and the address number of the called terminal. It is information.

The service control point 14 identifies the group to which the called terminal belongs based on the routing number information, and can identify the actual telephone number indicated by the speed dial number in the corresponding group based on the speed dial information. This identification process can be implemented with reference to a database table which corresponds to actual telephone numbers of a plurality of called terminals according to routing numbers and abbreviated numbers. 4 is a diagram showing an example of a speed dial management database table held by a service control point in a system for providing speed dialing and a method for providing the speed dialing in a mobile communication network according to the present invention.

As shown in Fig. 4, the speed dial management database table referred to by the service control point maps the actual phone numbers of a plurality of destination terminals belonging to a plurality of groups to one-to-one on two-dimensional coordinates of (routing numbers and shortcut numbers). It can be seen that it can be implemented.

When the service control point 14 determines the actual telephone number of the called terminal 15, the service control point 14 sends a response message to the analysis request to include the information about the actual telephone number of the called terminal. Reply).

The above-mentioned part is the most important process of the method for providing speed dialing in the mobile communication network according to the present invention. Once the speed dial number of the called terminal is converted into the actual phone number of the called terminal, the following process is a general call. It becomes the same as the process of performing the processing.

That is, the called side intelligent network switching station 13 returns an ANM message in response to the initial address message (IAM) from the calling mobile communication switching station 11 (150), and the called terminal 15 and the called side intelligent network switching station 13 ), When the incoming connection is established (16), the called side intelligent network switching station 13 sends back a response message (170) informing the calling mobile communication switching station 11, thereby, the calling mobile communication from the calling terminal (10) An incoming / outgoing call path is established up to the called terminal 15 via the switching station 11 and the called-side intelligent network switching station 13 (180).

2 is a configuration diagram showing an example of a system for providing speed dialing in a mobile communication network according to the present invention.

In this case, it is assumed that the calling terminal 20 and the called terminal 21 belong to the same group.

As mentioned above, the calling party home location register 21 should have a database that stores routing number (RN) information about a group to which the calling terminal belongs to the subscriber number of the calling terminal 20.

In addition, when the calling terminal 20 wants to make a call through the repeater 201 and the calling mobile communication switching station 200, the calling mobile communication switching center 200 inquires to the calling home location register 210. It is also as described above that the calling terminal 20 may know whether the calling terminal 20 is a subscriber of the speed dial number service only by transmitting a door.

And, the service control point 230 is a plurality of called terminals to determine the actual telephone number of the called terminal 21 based on the routing number and the speed dial information transmitted from the called intelligent network switching center (mobile communication switching center) 220 It should also contain a database that maps the actual phone numbers.

The embodiments of the present invention described above are not implemented only through the apparatus and the method, but may be implemented through a program for realizing a function corresponding to the configuration of the embodiment of the present invention or a recording medium on which the program is recorded. Implementation may be easily implemented by those skilled in the art from the description of the above-described embodiments.
