Abstract

PURPOSE: A method for notifying a connection request to a subscriber on a phone is provided so that a call connection rate can be increased by notifying the call request to the subscriber using a mobile communication system. CONSTITUTION: In a mobile communication system, when one subscriber calls the other subscriber, if the called subscriber is calling, a reception switching service of the called subscriber is confirmed. When the reception switching service is set up, the call is switched, and the call attempt is notified to the called subscriber. In case that the called subscriber does not set up an additional service, telephone number input is demanded to the calling subscriber. The telephone number of the calling subscriber is transmitted to the called subscriber. In detail, when a calling attempt exists(511), a transmission exchanger performs a routing demands of the subscriber(513), and judges whether the called subscriber is calling(515). In case that the called subscriber is not calling, the transmission exchanger takes a call processing step(519). When the called subscriber is calling, a destination exchanger confirms whether the subscriber sets up the additional service(521). If so, the destination exchanger switches a new call according to the additional service(525). Thereafter, the destination exchanger transmits the calling attempt to the corresponding subscriber(527). Accordingly, the subscriber can be informed of other call attempts on phone.

Description

HOW TO NOTIFY A CONNECTION REQUEST TO A BUSINESS PARTNER {METHOD FOR NOTIFING CALL ATTEMPT TO BUSY LINE OF SUBSCRIBER}

The present invention relates to a method of notifying a subscriber of a call in an access request, and more particularly, to a method of processing a message to be delivered according to service information of a subscriber that a new call attempt is made to a subscriber in a call.

Figure 1 shows outgoing and busy signals during a typical originating exchange and an incoming exchange.

Referring to FIG. 1, when an originating exchange 110 (Originating MSC) 110 attempts to make an origination call from a connected subscriber as shown in FIG. 1, a called party to which a called party to which the subscriber attempted to originate a ROUTREQ signal is connected is connected. <Terminating MSC; 120. Then, the destination exchange 120 transmits a routing (ACCDEN = Busy) signal in response to the routing request when the called party is busy with another subscriber. Transmit to 110.

2 shows a conventional call processing process.

Referring to FIG. 2, if there is an outgoing attempt in step 210, a subscriber router request (ROUTREQ) is performed in step 220, and in step 230, it is determined whether the called subscriber is busy. If it is determined that the subscriber is in a call, the process fails as a result of the router request return in step 240 and informs the calling subscriber in step 250. In contrast, if it is determined that the subscriber is not busy, the subscriber station succeeds in occupying the relay line in step 260 and performs the next procedure of call processing in step 270.

As described above, when a third party attempts to receive a call to a busy subscriber, the subscriber who has a call waiting function is failed only to the calling subscriber when the subscriber requests a routing and paging to the destination exchange where the called subscriber is located. Could not know that there was a ho attempt. Then, a failure is notified to the calling subscriber and the call is terminated or a new call attempt is made according to the mobile subscriber's mobile communication service procedure. Therefore, even if the incoming call transfer service or voice mail service of the mobile communication supplementary service is registered to the calling subscriber and the new call setup is successful, the information is not delivered to the subscriber in the first call. There is a problem that does not know whether this is done. In addition, there is a problem in that a call is routed to a subscriber who does not have an incoming call transfer service or a voice mail service, and the call fails even though the inter-state resources are used.

Accordingly, an object of the present invention is to provide a method for notifying that a subscriber who has requested a call has a subscriber in a mobile communication system.

Another object of the present invention is to provide a method for delivering a calling party's number to a called party in a mobile communication system.

In order to achieve the above object, the present invention provides a method of determining whether a call forwarding service of a subscriber is set when a called party is busy in a mobile communication system, and determines that the call forwarding service of the subscriber is set. If so, the process of switching the call, and sending a message informing the subscriber that there was an incoming call attempt during the call. In addition, the present invention, when the subscriber in the mobile communication system has not set the additional service, the calling party is requested to input the telephone number to deliver the calling party number to the called party.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. Specific details appear in the following description, which is provided to aid a more general understanding of the present invention, and it should be understood by those skilled in the art that the present invention may be practiced without these specific details. It will be self explanatory. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

3 shows a procedure in the case where the called subscriber has additional service information according to the present invention.

Referring to FIG. 3, the calling terminal 1 attempts to make a call through an adjacent base station 10. Then, the base station 10 notifies the originating switch 110 of the originating attempt of the originating terminal 1. Then, the originating exchange 110 transmits a routing request (ROUTREQ) signal to a destination MSC 130 that is connected to the called party that the originating terminal 1 has attempted to originate. Then, the destination exchange 130 requests the subscriber supplementary service information from the LRP 131 and receives the subscriber supplementary service information from the LRP 131. <320> Then, the destination exchange 130 receives the subscriber subscriber. If a call is in progress with another subscriber, it sends a routing (routreq [ACCDEN = Busy]) signal to the originating exchange 110 in response to the routing request. On the other hand, the destination exchange 130 notifies the called party 2 via the base station 20 that there is a call diagram.

Figure 4 shows the procedure when there is no additional service to the called party according to the present invention.

Referring to FIG. 4, the calling terminal 1 attempts to make a call through an adjacent base station 10. Then, the base station 10 notifies the originating switch 110 of the originating attempt of the originating terminal 1. Then, the originating exchange 110 transmits a routing request (ROUTREQ) signal to a destination MSC 130 that is connected to the called party that the originating terminal 1 has attempted to originate. Then, the destination exchange 130 requests the subscriber supplementary service information from the LRP 131 and receives the subscriber supplementary service information from the LRP 131. <320> Then, the destination exchange 130 receives the subscriber subscriber. In the case of a call with another subscriber, in response to the routing request, a signal for requesting a call (routreq [ACCDEN = Busy]) and a calling party number is transmitted to the calling exchange 110. &lt; 410 &gt; 110 transmits the calling party number to the destination exchange 120. <420> Then, the destination exchange 130 notifies the called party 2 via the base station 20. <330 ＞

5 shows a transmission process according to the present invention.

3 to 5, in step 511, if there is an originating attempt, the originating exchange 110 performs a subscriber routing request in step 513. In step 515, the originating exchange 110 determines whether the called subscriber according to the originating attempt is busy. If it is determined that the called party is not in a call, it succeeds in occupying the relay line in step 517 and performs the next procedure of call processing in step 519.

In contrast, if it is determined that the called subscriber is busy, the destination exchange 130 determines whether the subscriber's additional service is set in step 521. If it is determined that the additional service of the subscriber is set, in step 523, a result of the originating attempt is unsuccessful, and in step 525, the calling party changes to a new calling party according to the setting of the additional service. In step 527, the destination exchange 130 notifies the subscriber that an incoming call attempt has been made.

On the other hand, if the additional service of the subscriber is not set, the calling party requests the calling party after the switch application to the calling subscriber in step 533, and releases the postgraduate processing and resources after the calling number is cut in step 535. In step 537, the destination exchange 130 delivers the calling number to the called subscriber.

As described above, the present invention can recognize that there is a subscriber who wants to talk with the user by informing the subscriber that there is a call attempt in the mobile communication system. In addition, the present invention can perform a confirmation procedure for a mail system and an incoming call transfer call when a called subscriber has a mobile communication supplementary service function in a mobile communication system. In addition, the present invention has the advantage of increasing the access rate of the call and the call reliability of the subscriber by transmitting the calling number from the calling subscriber when the additional subscriber does not have additional services in the mobile communication system.
