The mobile terminal includes the step of displaying the location information of the incoming subscriber.

Hereinafter, described in detail with reference to the accompanying drawings, preferred embodiments of the present invention.

1 is a service providing flowchart according to a method for providing location information of a called party. As shown therein, a mobile station (MS) 10 serving as a communication means, a base station (BS) 20 which does not move in communication with the mobile terminal, and the base station are interworked with the base station. A mobile switching center that provides a circuit switching service to a mobile subscriber and configures an access point for user traffic between the terminal or another Mobile Switching Center (MSC) in the same or different mobile communication network, and the mobile terminal A home location register (HLR) having an in-network database function for managing subscriber level information and location information for providing a service at a fixed point in the network, and location information from the subscriber location register. It consists of other mobile switching centers that can be requested to respond. The operation and effects thereof will be described in detail as follows.

Add the following to the message used in PCS to provide the location information of the called party. First, as a part to be added to the location request return result parameter message, a spare field is added to the original trigger and used as a field for identifying whether a service is provided.

Second, service provision information is requested by allocating service provision information to a preliminary field of a progress indicator that is a parameter of an assignment as a part to be added to an allocation parameter message. In this case, when the progress indicator comes with a '01' command in the coding standard field, the progress indicator is recognized as a base station subsystem ID (BSS) in the progress description field.

On the other hand, since the progress indicator message is of variable length, the base station sub system ID required for providing the service can be transmitted from the mobile switching center to the base station controller. The base station controller adds a textual database field mapped to each base station sub system ID.

As in the service providing procedure shown in FIG. 1, a subscriber who can be provided with the location information of the other party attempts a call of the mobile terminal 10 (s1). Then, the base station 20 executes the 'CmpL3Info' command s2 for connecting the base station 20 and the mobile switching center 30 for the call processing, the 'CMSvcRQ' command s3 for the text service request, and the setup. Send a 'Setup' command (s4) to the mobile switching center (30). The mobile switching center 30 then processes the call (s5) and sends a 'LOCREQ' command to the subscriber location register 40 to request the calling party's information (s6). Upon receiving the 'LOCREQ' command, the subscriber location register 40 transmits a 'RoutReq' command for a transmission request to another mobile switching center 50 in which the location of the called subscriber is registered (s7).

The mobile switching center 50 then sends a 'routreqAck' command to the subscriber location register 40 in response to the request (s8). Thus, subscriber location register 40 receives a Temporary Local Directory Number (TLDN) in response. The subscriber location register 40, which knows that the calling subscriber is a subscriber who is provided with the location information of the called subscriber, transmits the TLDN and the base station sub system ID to the mobile switching center 30 again. The mobile switching center 30 hands over the base station secondary system ID to the mobile switching center 30 to which the calling subscriber belongs through the 'locreqAck' command (s9). Then, the mobile switching center 30 transmits the base station secondary system ID of the called subscriber through assignment to the base station controller (BSC) in the base station 20 again (s10). Then, the base station controller reads the database and transmits the position of the base station 20 to which the called party belongs to the mobile terminal 10 (s11). At this time, the base station controller transmits the character information corresponding to the base station sub system ID to the mobile terminal 10, and the mobile terminal 10 displays the location information of the called subscriber.

As described in detail above, the present invention has an effect of obtaining the location information of the other party through the terminal without waiting for the other party to make a call even when the subscriber is urgent when the state where the telephone call is impossible continues.
