Description

Method for the notice service of interworking originating call in a wire / wireless telecommunication network}

The present invention relates to a call incomplete (call setup failure) notification service method in a wired / wireless communication network, and more particularly, when two communication subscribers make a call incomplete state by calling each other, they are simply busy. In addition to the notification, the other party also informs the caller that he or she is busy, or performs call processing only for a call establishment request that is earlier in origin, and notifies each other about a call establishment request that is late in origin. The present invention relates to a mutual call notification service method in a wired and wireless communication network.

Today, through caller ID (CID) service, missed call indication, and short message transmission for an incomplete call in an unreceivable situation, subscribers can be fully informed about the missed call.

However, in the current call incomplete (i.e., call setup failure) notification service, the calling subscriber is only responsible for the cause of the call incomplete, such as the other party is busy, the other terminal is powered off, or the other party is not answering the call. You can let them know.

Therefore, when the called subscriber also makes a call to the calling subscriber (that is, when two subscribers call each other), the called subscriber simply informs that the user is busy. Without the additional method of notifying the fact that you are not able to inform the other party, and also due to the incomplete call redundancy or there was a problem that abandon the call.

The present invention has been proposed to solve the above problems, and when two communication subscribers make a call incomplete state by making a call between each other, the call is not merely informed that the call is busy and the other party also By notifying each other that the call is in progress, or informing about the call setup request that is late in origin, and performing call processing only for the call setup request that is outgoing, it is possible to prevent unnecessary re-calls and to quickly communicate with each other. An object of the present invention is to provide a call notification service method in a wired / wireless communication network that allows call setup to be easily performed.

In the present invention for achieving the above object, in the mutual call notification service method in a wired or wireless communication network, the called side exchange is called to the called terminal in response to a call setup request from the calling terminal transmitted through the wired or wireless communication network. Call setup step of performing setup; If the call setup fails due to the call of the called terminal, the called side exchange checks the telephone number of the called party called by the called terminal, and compares the telephone number with the calling number received from the calling exchange. ; As a result of the comparison of the phone numbers, if the phone numbers are the same, the call exchange response message indicating that the called exchanges are calling each other is transmitted to the calling exchange, and if the phone numbers are different, the call answering message indicating that the call is busy. Call setup result response step of transmitting 'to the calling exchange; And a call completion notification step of transmitting, by the calling exchange, a notification message corresponding to the received response message to the calling terminal.

In another aspect, the present invention, the redundancy guide step of transmitting the 'recall guide message' by the calling side exchange receiving the mutual call response message to the calling terminal; And a call processing retry step in which the originating exchange retryes call processing in response to a rerouting request from the originating terminal.

On the other hand, the present invention, in the mutual call notification service method in a wired or wireless communication network, a call in which the called side exchange to perform the call setting to the called terminal in response to a call setup request from the calling terminal transmitted through the wired and wireless communication network Setting step; If the call setup fails due to the call of the called terminal, the called side exchange checks the telephone number of the called party called by the called terminal, and compares the telephone number with the calling number received from the calling exchange. ; As a result of comparing the telephone numbers, if the telephone number is different, the called exchange transmits a 'call answering message' indicating that the call is in progress to the calling exchange, and the calling exchange receives the busy answering message. A busy notification step of transmitting a 'call notification message' corresponding to a response message to the calling terminal; And if the phone number is identical, the called exchange compares the calling time of the two terminals, stops the call processing for the call establishment request with the late calling time, and is calling each other with the late calling time. And transmitting the 'intercall call notification message' to notify the call, and if the call of the terminal is delayed, the call forwarding notification / call processing follow-up step of continuing the call processing for the call establishment request preceding the call point.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a wired / wireless communication network to which the present invention is applied. Side line telephone, "121", "133" is base transceiver system (BTS), "122", "132" is base station controller (BSC), "123", "134" is calling party / Called party mobile exchange (MSC), " 125 ", " 134 "

First, each function is briefly described as follows.

The mobile terminals 101 and 141 have a unique number (phone number) and are terminal devices carried by the subscriber. The base stations 121 and 133 are radio stations, which are in charge of communication with the mobile terminals, and are devices capable of transmitting radio signals to or receiving radio signals from the mobile terminals in the wireless communication section. The base station controllers 122 and 132 control the base stations 121 and 133 and manage radio resources between the mobile switching centers 123 and 131 and the base stations 121 and 133, and control the base stations 121 and 133 and the base station controllers. Hand-off function is performed between 122 and 132. The mobile exchangers 123 and 134 store the location and service profile of the mobile terminal, and perform an exchange function to connect a call path to enable a call. Although not shown, the mobile communication system includes a home location register (HLR), which stores the location of the subscriber's mobile terminal, stores the service profile of the subscriber, and stores the service profile information of the subscriber. The database you are doing.

On the other hand, wired telephones 102 and 142 are basically the same as mobile terminals 101 and 141 in that they have a unique number (telephone number) and are intended for communication, but are wired to a wired network such as a public telephone network. The difference is that mobility is limited. Like the mobile switchers 123 and 134 described above, the wired switch 124 and 135 is a device that enables a call by connecting to a call path by performing an exchange function. In the description process of the present invention, simply referred to as a "terminal", which is a generic term for a mobile terminal and a fixed line telephone, and simply referred to as a "exchange", which collectively refers to a mobile exchange and a fixed line exchange.

On the other hand, the switchers 125 and 134 are devices for interworking a mobile communication network and a public telephone network, that is, interworking with a mobile switch and a wired switch, and serve to enable a call between a user of a mobile terminal and a user of a wired telephone.

2 is a flowchart illustrating a method for notifying each other of an outgoing call in a wired or wireless communication network according to the present invention.

When the originating exchange 123, 124 receives a call setup request from the originating terminal 101, 102 (201), accordingly, the exchange at the originating exchange 123, 124 and the called party (i.e., the called side exchange) Call processing (call setup) is performed between the operations 131 and 135 (202).

That is, the call setup request by the mobile terminal 101 may be received by the destination mobile switch 131 or the base station 121, the base station controller 122, the mobile switch 123, and the switch 125. The landline exchange 135 is reached. Similarly, a call setup request by the wireline telephone 102 arrives at the destination mobile switch 131 or the wired switch 135 through the wired switch 124 and the switch 125. Through this process, call processing between the calling exchanges 123 and 124 and the called exchanges 131 and 135 is performed.

Thereafter, the destination exchange 131, 135 performs a call attempt to the destination terminal 141, 142 (203), at which time the destination terminal 141, 142 is in a busy state, or the power is turned off. When the call is turned off or when an attempt is made to make a call to the calling terminal 101 or 102, the call Call becomes incomplete (call setup failure).

When the called side exchange 131, 136 recognizes that a call incomplete state is caused by the originating attempt (calling) of the called terminal 141, 142, the called terminal 141, 142 attempts to make a call. The subscriber's telephone number is checked and compared with the calling party's number (ie, the telephone number of the calling party's terminal) received from the calling side exchanges 13 and 124 (205).

As a result of the telephone number comparison, if the telephone numbers are the same, the destination exchanges 131 and 136 transmit a response message ('intercom response message') to the calling exchange 123 and 124 indicating that they are calling each other (206). ), The originating exchange (123, 124) receiving the response message transmits a 'mutual call notification message' to the calling terminal (101, 102) to inform the calling subscriber that the call is incomplete due to mutual calling. (207). As a result, the calling party recognizes that call setup cannot be made because the other party is also sending to the calling party.

As a result of the phone number comparison, if the phone number is different, a response message ('call answering message') indicating that the other party (the called party) is busy is transmitted to the calling exchange (123, 124) (208), and the response message. The sending side exchanges 123 and 124 receiving the transmission transmit the 'call notification message' to the calling terminal 101 and 102 (209).

On the other hand, the sending side exchange (123, 124) transmits a 'recall guide message' confirming the intention to re-send the calling subscriber, while transmitting the 'intercall notification message' (207, 209), accordingly the calling terminal ( If there is a request for redial from 101, 102, the call processing process is performed again.

As described above, by allowing the calling party to inform the caller of the intention to redial, to the called party that the calling party is calling to the calling party without interrupting the call setup operation (that is, hanging up the phone) and dialing again. It allows you to attempt to make a call again. In this process, there is a possibility that the simultaneous simultaneous call may occur again, but the counterpart subscriber may recognize that the call is being sent to him, thereby increasing the call success rate.

Next, another embodiment will be described.

The other process is the same as the above description, but the processing method in the case where the telephone numbers are the same as a result of the telephone number comparison is only different as follows.

When the called party exchanges 131 and 136 have the same telephone number, the call exchange points are compared between the two terminals, and the message indicating that the call is terminated and the call is sent to the corresponding terminal for the call setup request with a late call time (' Mutual call notification message ') is sent. Because of this, when the subscriber who has recognized that the other party is also sending to him through the 'Call Call Notification Message' stops the call, the calling point (calling point) continues the call processing for the previous call setting request. By completing, a call can be made between both subscribers.

In other words, the present embodiment is to inform the subscriber that the call is coming later in time to tell that the incoming signal is coming so that no further call attempts can be made, so that the call of the priority subscriber can be received.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited by the drawings.

The present invention as described above is merely a fact that if the call completion (call setup failure) is due to the calling attempt of the other party's caller (that is, when two subscribers call each other), the call is simply busy Unlike the existing 'in-call notification service' that provides notification, by providing a notification service that notifies that the call is due to mutual call, it is possible to grasp the call intention of the other subscriber (that is, whether the other party also wants to talk to the caller himself). In addition, there is an effect that the inconvenience of having to delay the call setup to the next opportunity or resend several times is inevitable.

In addition, the present invention, by inducing the interruption of the transmission attempt of one subscriber through the mutual call notification service, there is an effect that the call is established between each other without the re-call process.

In addition, the present invention, by providing a call notification notification service (that is, while notifying that the call is due to the call between each other) automatically checks whether the calling party has a re-sending intention, call processing, so that the call is re-established without a call back It has the effect of making the attempt quick and easy.

In addition, the present invention, by comparing the call time, to the subscribers with a late call time by sending the message 'intercall being sent' to induce outgoing call, by continuing to perform the call processing to the subscriber before the call time, such as redial There is an effect of setting up a call between both subscribers more quickly / easily without a procedure.
