Abstract

PURPOSE: A method for setting up a call to a place adjacent to a subscriber in a mobile switching center is provided to connect a call to a special number institute adjacent to the position of a mobile subscriber by extracting the area code of an area, in which a base station is located, using the identification information of the base station and inserting it before a dialed special number. CONSTITUTION: A mobile switching center constructs a base station-to-area code database by relating the area codes of districts, in which base stations are located, to base station IDs. In case that a mobile subscriber attempts a call after dialing a special number(S10), the mobile switching center searches the database using a base station ID contained in the call setup request message and extracts an area code corresponding to the present place in which the subscriber is located(S12). The mobile switching center makes a new telephone number by inserting the extracted area code before the dialed special number and attempts a transit call to a fixed network(S14).

When the area code is extracted, the area number is extracted by searching a database in which the area code corresponding to the base station identification information is stored as the base station identification information.

Hereinafter, with reference to the accompanying drawings it will be described in detail with respect to a call setup method from the exchange to the subscriber in accordance with a preferred embodiment of the present invention.

In order to implement a method for establishing a call to a subscriber's local area in an exchange according to the present invention, as shown in Table 1, a base station-to-area number database is generated by mapping the area number of a region where a base station is located to a base station ID at an exchange. After the mobile subscriber attempts to call the special number, he extracts the area code of the location where the mobile subscriber is located from the call setup request message from the base station to the switching center and inserts the extracted area code before the special number. Create a new phone number and try the relay on the fixed network.

Base station ID Area code 00000000-00000100 02 : : 11111110 ~ 11111111 0694

The mobile terminal receives a service of a base station close to where it is located, and each base station has a unique name and ID, and this information is also shared by an exchange in charge of call processing through the base station.

As shown in Table 1, after the exchange creates a base station-area area code database in which the area number of the area where the base station is located is mapped to the base station ID, the mobile subscriber dials the special number as shown in FIG. When attempting (S10), the base station ID is searched among the internal databases of the exchange using the base station ID included in the call setup request message entered through the base station to the switching center, where the current mobile subscriber is located. Extract the area code of the place (S12). Subsequently, the area code extracted in step S12 is inserted in front of the special number dialed in step S10 to create a new telephone number and attempt a relay call to the fixed network (S14).

That is, as shown in FIG. 2, when the subscriber dials 119 for the fire report in the area of base station 1, which is serving the Anyang area as the service area, a call setup request message through a wireless channel between the mobile terminal and the base station. When is reached to the mobile communication switch via base station 1, the mobile communication exchange receiving the call setup request message searches the database and uses the ID of the originating base station included in the call setup message to assign the area code to the calling base station. 0343 is extracted, the extracted area code 0343 is inserted before the special number to generate a new special number, and the call is made to the newly created telephone number.
