4 is a flowchart according to call origination and location information update according to the present invention.

First, the mobile terminal is initialized by the user (41). The initialization is performed in order for the mobile terminal to be able to transmit and receive. After the initialization of the portable terminal is performed, the terminal may occur in the reception standby state by updating the location information 42 by the terminal itself, generating a terminal incoming signal 43 by a third party, and generating a terminal signal by the terminal user. It is divided into three of (44).

The update 42 of the location information by the terminal updates the new current location identification number when the terminal communicates with the nearest base station.

In the case of an incoming call to the mobile terminal by a third party (43), it occurs when an unspecified third party calls the corresponding mobile terminal, and the local exchange 12 that manages the subscriber line that initiated the call is the called mobile phone. The call is passed to the toll exchanger 11 to which the subscriber position register 10 is connected.

The toll exchanger 11 waits for the call returned to the user for a while, searches for the location of the mobile terminal after searching the subscriber location register, and then manages the base station in which the mobile terminal is located in the call in standby state. 12). The base station in which the mobile terminal is currently located broadcasts the information from the information transmitted through the local exchange 12 through the wireless interface in which the mobile terminal is located to call the corresponding terminal (44).

In the case of a mobile terminal originating signal by the user (45), the user originates an originating signal in his or her own base station area 15 or another base station area. At this time, the local exchange managing the base station identifies the incoming / outgoing mobile phone service having a special number and is charged to the mobile terminal identification number that sends the call, not the subscriber line where the call is started.

5 is a detailed flowchart of an initialization performing step 41 of the portable terminal.

Initialization of the portable terminal is performed by the user connecting the power connection switch of the portable terminal to initialize the input / output device (51), after the initialization of the transmit and receive RF device (52), and then of a predetermined length for periodic location information update. This is completed by starting 53 a timer.

6 is a detailed flowchart of the periodic automatic location information updating step 42 of the portable terminal.

The periodic location information update of the portable terminal is started by the end of the timer started during the initialization process of the portable terminal 14 inside the portable terminal. When the timer expires, the portable terminal exchanges an identification number with the nearest base station through the wireless interface according to a previously stored program (62). If the newly obtained base station identification number is the same as the base station identification number currently stored in this process, the process is terminated and a new timer is started (63, 65).

On the contrary, if the compared base station identification number is different from the stored base station identification number, the stored base station identification number is replaced with the newly received base station identification number (63, 64), and the user's location information stored in the subscriber location register is updated. Perform a procedure (65) and start a new timer (66).

7 is a detailed flowchart of the incoming call generation step 43 of the portable terminal.

If any third party initiates a call to the called mobile terminal (71). After checking the special number 31 at the local exchange, 72, the call is routed to the subscriber location register which stores the subscriber information via the toll exchanger (73). The toll exchanger checks the service identification number 24 of the corresponding mobile terminal stored in the subscriber location register (74) and if the mobile terminal is located in its initial location registration base station, it performs routing to the mobile terminal location unique number (22). If the terminal is in the area of the other base station (75, 77) and performs routing to the provisional position unique number 23 of the mobile phone terminal (75, 78).

8 is a detailed flowchart of the portable terminal incoming signal processing step 44.

When a call to the mobile terminal at the corresponding base station is initiated by routing 77 and 78 to the provisional position unique number 23 described above with reference to FIG. 7, the mobile terminal receives the received mobile terminal. After the identification number is the same as its own (82), when it calls itself, it makes a call connection in response to the base station through the radio interface (83).

9 is a detailed flowchart of the portable terminal signal generation step 45. When a user of a mobile terminal initiates an outgoing call in an area of a base station, the local exchange jurisdiction of the base station sees the mobile terminal identification number transmitted through the base station and knows that the call is receiving an incoming / outgoing mobile phone service (91). . Accordingly, the local exchange determines the charging to the outgoing mobile terminal identification number rather than the subscriber line that generated the call, unlike the general call (92), and then performs the routing (93). Therefore, the present invention is configured as described above, the existing mobile phone users at a small additional cost by adding an additional function using a special number directly connected to the database for storing and updating the location information of the subscriber to the public public telephone network Since it is possible to quickly provide a personal communication service capable of incoming and outgoing calls while moving, there is an effect of providing superior economics compared to the conventional method of configuring a separate network.
