The called state display server 20 of the present invention converts the current state information of the called terminal (MS) 28 sent from the called exchanger (MS) 22 into text or image data to the calling exchange (MSC) 16. It serves to convey. In this case, the current state information of the called terminal may be converted into voice data and transmitted to the originating exchange (MSC) 16.

2 is a flowchart illustrating a method of displaying a current state of a called terminal on a calling terminal in a mobile communication network according to the present invention. 2, the present status display method of the called terminal according to the present invention is as follows.

First, when the called party number of the subscriber is dialed in the calling terminal (MS) 10, the called terminal (MSC) 16 is connected to the calling exchange (MSC) 16 through the base station (BTS) 12 and the base station controller (BSC) 14. Request call connection with (28). (S10)

The originating exchange (MSC) 16 contacts the home location register (HLR) 18 to determine the location of the originating terminal (MS) 10 (LOC [Digits]), and the home location register (HLR) 18. ) Transmits a Routing Request (RTR) Invoke message to the destination exchange (MSC) 22, which assigns a Temporary Local Directory Number (TLDN) for call routing through the signaling network. At this time, the RTR call message includes the mobile identification number (MIN) of the subscriber who is currently communicating.

The destination exchange (MSC) 22 then determines whether the destination terminal number included in the MIN is registered in the additional service of the present invention for providing its current status information to the originating terminal (MS) 10 (S12).

As a result of the determination of S12, if the terminating terminal (MS) 28 is registered in the additional service for displaying its current state information on the other terminal, the procedure proceeds as follows.

The destination exchange (MSC) 22 allocates the TLDN when the MIN in the RTR call is included and sends it to the home location register (HLR) 18 including the TLDN in the RTR forwarding. The home location register (HLR) 18 includes the TLDN assigned by the destination exchange (MSC) 22 in the subscriber's location information message (LOC forwarding) and sends it to the originating exchange (MSC) 16. Thereafter, the MSC 16 transmits a location request message (LOCREQ: Location Request Invoke) to the home location register (HLR) 18 to serve the area where the called subscriber is located. Request routing information up to (S14).

The Home Location Register (HLR) 18 sends a Routing Request Invoke (ROUREQ) to the destination exchange (MSC) 22 to request a routing number to set up the call to the subscriber and to receive the MSC ( In 22), a Routing Request Return Result is sent to the Home Location Register (HLR) 18 to inform the routing number of the call setup. The Home Location Register (HLR) 18 returns the routing number to the originating exchange (MSC) 16 via a Location Request Return Result to allow the call to be processed (S16).

In this way, the MSC 22 sends a message requesting the current status information to the destination terminal MS 28 while the call terminal MS 28 transmits its current status information. The included response message is forwarded to the destination exchange (MSC) 22 via the base station (BTS) 26 and the base station controller (BSC) 24. The destination exchange (MSC) 22 transmits the current state information of the called terminal to the called state display server 20 (S18).

The called state indication server 20 converts the current state information of the called terminal MS 10 into the set text or image data and transmits it to the originating exchange (MSC) 16. The originating exchange (MSC) 16 transmits the data of the called state indication server 20 to the originating terminal (MS) 10 through the base station (BTS) 26 and the base station controller (BSC) 24. S20)

The calling terminal (MS) 10 displays the current status information of the called terminal provided by the called state display server 20 as a text or an image. (S22) For example, since the call connection is transferred, the calling terminal (MS) 10 ) Displays a text message " connecting call " or a set graphic image corresponding thereto.

While the current status information of the terminating terminal (MS) 28 is displayed, the originating exchange (MSC) 16 sets up a call path to the terminating exchange (MSC) 22 using the routing number. Perform the connection (S24).

Even if a call connection is made between the calling terminal (MS) 10 and the called terminal (MS) 28, the receiving exchanger (MSC) 22 repeats the steps S18 to S22, and when the call connection is terminated, Terminate the service.

According to the present invention, after the call is connected, the calling terminal (MS) 10 displays the called terminal response, which is the current status information of the called terminal (MS) 28, the call, the call connection termination status, etc. as text data or image data. do. For example, a text message (such as voice data can be output) or "Graphic Answering Device Answered", "Currently Busy", "Call is ended", or a graphic image set to correspond to the calling terminal (MS). 10) is displayed on the display.

In addition, the present invention indicates that "the called terminal is now absent" on the display of the calling terminal (MS) 10 even when a call is not connected between the calling terminal (MS) 10 and the called terminal (MS) 28, or When switching to another supplementary service, a text message " switched to voice mailbox " (which can also be output as voice data) or a corresponding set graphic image is displayed on the display of the calling terminal (MS) 10. FIG.

On the other hand, the present invention, if not registered in the additional service in step S12, routing, call processing, call between the calling terminal (MS) 10 and the called terminal (MS) 28 as described above step S14, S16, S24 Perform the connection process. (S26 ~ S30)

As described above, the present invention transfers the current status information of the destination terminal to the service server in the destination exchange when the call is connected, after the call is connected, when switching to the missed or other additional service and converts it into a text or graphic image By providing to the calling terminal through the calling exchange, the subscriber of the calling terminal can immediately see the displayed text or graphic image to know the current state of the called terminal.

On the other hand, the present invention is not limited to the above-described embodiment, various modifications are possible by those skilled in the art within the spirit and scope of the present invention described in the claims to be described later.
