Abstract

The present invention relates to a method for notifying an individual mobile communication terminal subscriber of an unconditional incoming call transfer occurrence in a personal communication exchange. In the related art, a mobile communication terminal is used to subscribe to an incoming call switching service. If the application is switched to the terminal to which the call has been forwarded due to overlooking without overturning the incoming call transfer by overwriting it, the subscriber may not receive the call to his / her phone because the subscriber does not know that the call transfer service is released. In the case of overlooking the release of the call forwarding service by receiving the call forwarding service, there is a drawback that the call cannot be received because the call to be received by the own terminal is received by the other terminal.By not releasing the automatic call forwarding service, the subscriber may be notified of incoming calls without alarm through the alarm sound, and the subscriber who receives it may release the automatic call forwarding service so that the subscriber can recognize the alarm sound and release it. If the called party is a caller capable of displaying the calling number, the called party can receive the calling number and the called party can connect the call to the call that is not completed by the incoming call conversion. .

The configuration of the present invention is a mobile call control for controlling a mobile call coming through a plurality of base stations (10-1, ..., 10-n), a plurality of base station controllers (10, ...) and base station controller matching block 110 The subscriber's information is sent to the personal communication switch 20 via a block 120, a visited subscriber management block 170 that manages mobile subscriber information within the personal communication switch 20, and a home location register matching block 150. And a home location register 30 that is provided and provided.

Hereinafter, with reference to the accompanying drawings, it will be described in detail a preferred embodiment of the present invention.

1 is a schematic block diagram of a personal communication switching system for explaining a method of generating an incoming call transfer alert, FIG. 1 is a schematic block diagram of a personal communication system for explaining a method for generating an incoming call transfer alert. As a configuration diagram, each of the first, ..., N-th base stations 10-1, ..., 10-n wirelessly connects to a personal communication subscriber (MS) in the corresponding area.

The plurality of base station controllers 10, ... are wired connected to the plurality of base stations 10-1, ..., 10-n, and the base station controllers 10, ... are connected to the plurality of base stations 10-1. ,..., 10-n, and control a process of wirelessly receiving a signal from each base station 10-1, ..., 10-n and processing the received signal.

The personal communication switch 20 is connected to a plurality of base station controllers 10, ..., and is connected to a plurality of base station controllers 10-1, ..., 10-n. ) Call is transferred to other exchange and local subscriber by connecting call.

The base station controller matching block 110 serves to convert a message coming from the base station controller 10 into a signal usable by the personal communication exchange 20.

The visited subscriber management block 170 serves as a database for receiving and temporarily storing and managing information of a plurality of subscribers in the personal communication switch 20.

The home location register 30 also serves as a database containing subscriber information such as subscription information of subscribers and other service information, for example, additional service information.

The home location register 30 communicates with a number of personal communication exchanges 20 and sends and receives subscribers' information to each visited subscriber management block 170 inside each personal communication exchange 20.

The mobile call control block 120 is divided into an outgoing mobile call control block and an incoming mobile call control block. For example, the outgoing mobile call control block requests outgoing subscriber information from the visited subscriber management block 170 to obtain outgoing subscriber information.

The outgoing mobile call control block sends a called number to a number translation block (not shown) to request number translation.

The incoming mobile call control block is a block for controlling the mobile call of the subscriber to be received. When the paging request is transmitted to the base station controller 10, the base station controller 10 returns to the corresponding base station 10-1 to the called terminal 254. After transmitting the signal, the called terminal again transmits a paging response to the base station 10-1, the base station controller 10, and the called mobile call control block.

The visited subscriber management block 170 forwards the paging request to the mobile call control block 120 where the called subscriber resides.

The home location register matching block 150 is responsible for registration between the home location register 30 and the personal communication switch 20, and communicates with the home location register 30 with the signal of SS NO. Receives and sends a signal, switches to an internal message commonly used at the personal communication exchange 20, and converts an internal signal of the personal communication exchange 20 into an SS NO.7 message so that the message is sent to the home location register 30. Also

Then, the home location register matching block 150 serves to notify the home location register 30 access error when the incoming location information request is received from the originating mobile call control block 120.

Referring to FIG. 2, the steps for describing a method for generating an incoming call transfer alert in a personal communication system will be described. The base station 10-1, ..., 10-n, the base station controller 10, ... In step 202, the home location register 30 receives a call request of an originating subscriber through the base station controller matching unit 110 and the home location register 30 (step 202).

The home location register 30 determines whether the called party requested by the calling subscriber is a subscriber who is determined to automatically transfer the call (step 204).

If it is determined in step 204 that the called party is not subscribed to the call forwarding service, or if it is subscribed but not using the service, the calling party and the called party are connected or connected to the calling party according to the prior art. The call is terminated by ending the call (step 206).

If it is determined in step 204 that the called party subscribes to the automatic call forwarding service and is currently using the service, an information command message including the called party number, the calling party number, an alarm tone, and the like is received in the personal communication switch 20. Transmit to home location register matching block 150 (step 208).

Home location register matching block 150 transmits the information command message received in step 206 to visiting subscriber management block 170 (step 210).

The visited subscriber management block 170 receiving the information command message determines whether the indication of the calling party's number is possible to the terminal of the called subscriber (step 212).

If it is determined in step 212 that it is impossible to display the calling party's number to the called party's terminal, an information command message excluding the calling number indication information is transmitted to the mobile call control block 120 (step 214).

If it is determined in step 212 that the calling subscriber's number can be displayed to the terminal of the called subscriber, an information command message including the calling number indication is transmitted to the mobile call control block 120 (step 216).

The mobile call control block 120 then sends a call command for the information command message to the base station controller matching block 110 which matches the personal communication exchange 20 and the base station controller 10, ... (step 218). ).

The base station controller matching block 110 transmits an information command message including an alarm sound to the called terminal through the corresponding base station 10-1,..., 10-n (step 220).

The called terminal receiving the information command message receives an arc (ACK) signal indicating that it has received the information command through the base stations 10-1, ..., 10-n and the base station controller 10, .... Transmit to communication exchange 20 (step 222).

The base station controller matching block 110 in the personal communication switch 20 sends an arc signal received from the called party to the mobile call control block (step 224).

The mobile call control block 120 transmits the arc signal received from the called party to the visited subscriber management block 170 (step 226).

Visiting subscriber management block 170 transmits the arc signal received from the called subscriber to home location register matching block 150 (step 228).

Home location register matching block 150 transmits an arc signal received from the called party to home location register 30 (step 230).

As described above, according to the present invention, the receiving subscriber does not release the previous automatic call forwarding service, thereby notifying the incoming unanswered call that may occur, and the subscriber who receives it cancels the automatic call forwarding service. It can be set and enabled so that the subscriber can recognize it as an alarm tone and release it.If the called party is the subscriber who can display the calling number, the called party receives the calling number and the called party reverses the call for the incomplete call transfer. There is an effect that can be linked.

The principles of the invention have been described above in connection with specific devices, which are described by way of example only, and are not limited to the spirit of the invention as described in the appended claims.
