The present invention relates to a call state notification service of a mobile communication terminal, and more particularly, a callable notification of a mobile communication terminal capable of providing a call state or a callable state of a called terminal to a calling terminal through a predetermined message channel. It is about the system.

In general, wired / wireless telecommunications operators have received a good response from subscribers by implementing a call-related additional service called "caller number display service". This caller ID display service is also commonly referred to as a "Caller ID" service, that is, a "CID" service. The CID service is designed to enable callers to make calls using the Signaling Committee in accordance with the International Committee on International Telephone and Telegraphy (CCITT), the current International Telecommunications Union-Telecommunication Standardization Sector (ITU-T) V.32. It is a service that provides information such as name or telephone number as a unique identification number, time information according to call origination and incoming call.

Currently, the CID service is widely used in terms of the benefits of protecting the privacy of the recipient in connection with the phone call and in protecting the option of receiving a call through the caller's confirmation. For example, when a call is received through a wired or wired / wireless phone, not only the caller information displayed on the display window can be checked, the call can be selectively selected, and the call can be received from a mobile phone which is a mobile communication terminal using a mobile communication network. The caller information that appears on the display window at the time is checked to make a selective call.

In addition to such a CID service, a subscription network identifier display service has recently been disclosed which provides a caller ID display service by integrating a mobile communication identification number. According to the published literature, a system for providing a mobile communication identification number and a caller ID display service, while performing a wireless telephone call through a mobile communication network, together with the telephone number of the calling party terminal when an incoming call is received, the calling party A mobile terminal for receiving and displaying an identifier of a mobile communication company subscribed to the terminal; In connection with the mobile communication network, when there is a call request from the mobile terminal, the identifier display providing server for transmitting the phone number of the mobile terminal with the identifier of the mobile communication company subscribed to the mobile terminal; And an identifier display database storing identifiers of a plurality of mobile communication companies as data. Therefore, when an incoming call is received to any terminal, the called party recognizes additional information of the calling terminal as receiving caller number information (CID) and identifier information of the corresponding mobile communication company for the calling terminal.

As described above, the display of the caller or the display of the identifier of the communication company cannot but recognize only the call state of the called terminal. Thus, when an outgoing call is not received by the caller and by the called party's environment, the called party requests a call back call to the caller based on the caller indication information. However, the called party often does not make a callback call for an outgoing call number that is not already recognized, which causes the caller not to know when the call was made with the called party, resulting in inconvenience of repeating the request with the called party. .

The present invention has been made to solve the above problems, and an object of the present invention is to notify the calling terminal that attempted to make a call or a busy state for the called party, thereby increasing the call success rate of the caller. A communication state notification system of a communication terminal.

Another object of the present invention is to use a short message or a multimedia message to notify the call state or busy state of the called terminal, the call available state of the called terminal is quickly notified to improve the quality of the communication service The present invention relates to a call state notification system of a mobile communication terminal.

Still another object of the present invention is to notify a call state or busy state of a called terminal, by adding a callback signal, and a call state notification system of a mobile communication terminal, which can easily make a caller's re-call request. It is about.

A callable notification system of a mobile communication terminal according to an aspect of the present invention for achieving the above object is for using the mobile communication network including the calling exchange and the called exchange to notify the calling terminal of the available state for the called terminal. In a communication system, a registration for a callable notification service for the called terminal connected to the called exchange is received, the communication state of the called terminal is monitored, and the calling information for the calling terminal is determined according to the communication state monitoring result. A home location register for transmitting the destination information and the service indication information for the destination terminal to the originating exchange; And a service server for providing callable notification information for notifying the calling terminal that the calling terminal is capable of calling the called terminal in response to the service indication information provided from the calling exchange.

According to a preferred embodiment of the present invention, the call state monitoring for the called terminal, when the call request call of the calling terminal to the called terminal is not completed, it is possible to call to the called terminal later from the communication state of the called terminal It is characterized by determining whether or not.

In addition, the communication state of the called terminal is characterized in that the operating state, such as telephone calls, Internet connection.

The service server may be a CID server having a caller ID service function, and the call notification information is caller indication information (CID) including a guide message for notifying that the call is possible with the called terminal. It features.

In addition, the service server is interlocked with a predetermined message server, the service instruction information received from the service server starts the message server, characterized in that a message corresponding to the callable notification information is provided to the originating exchange. do.

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

1 is a block diagram showing a callable notification system of a mobile communication terminal according to the present invention. As shown, in a mobile communication network including an originating exchange 103 and a terminating exchange 105, accepts a registration for a callable notification service for a terminating terminal 107 connected to the terminating exchange 105, The call exchanger 103 monitors a call state of the called terminal 107 and transmits call information about the call terminal 101 and call information about the call terminal 107 and service indication information according to the call state monitoring result. The originating terminal 101 that the originating terminal 101 is capable of making a call with the called terminal 107 in response to a home location register 113 for transmitting to the service information and the service indication information provided from the originating exchange 103. It is composed of a service server 111 for providing callable notification information for the notification.

Call state monitoring for the called terminal 107, when the call request call of the calling terminal 101 to the called terminal 107 is not completed, the called terminal 107 from the communication state of the called terminal 107 later This is to determine whether or not the call can be made. Here, the communication state of the called terminal 107 indicates a device operating state such as a telephone call, an Internet connection, etc., and it is regarded as a callable or a callable state after the point at which device operation is terminated.

The service server 111 may be configured as a CID server having a caller ID service function, and thus, the callable notification information includes caller indication information including a guide message for notifying that the caller can call the destination terminal 107. (CID). That is, when the service server 111 is a CID server, the service server 111 will provide a predetermined guide message notifying that the caller is in a state of being able to talk with the current destination terminal, including caller information. The guide message is a preset formatted message.

On the other hand, the service server 111 notifies the calling terminal 101 of the callable state by using a caller ID service (CID), but if necessary, a short message (SMS) or a multimedia message (MMS) of a predetermined format is required. Can be used to provide callable notification information. Therefore, the service server 111 is interlocked with the message server 109, and the service instruction information received by the service server 111 starts the message server 109 so that the message corresponds to the callable notification information. Is provided to the originating exchange 103.

Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings.

2 is a flowchart for explaining the main operation of the present invention. As shown, in step S201, the called terminal 107 performs a service registration for receiving the callable notification service of the mobile communication terminal. At the time of service registration, the called terminal 107 performs user authentication and billing according to a predetermined procedure. The service registration request is provided to the home location register 113 through the destination exchange 105, and the home location register 113 stores and manages terminal information and service registration information for the destination terminal 107.

In step S203, the calling terminal 101 performs an incoming call request for a call with the called terminal 107. At this time, the source terminal 101 is switched to the destination exchange 105 via the source exchange 103, the destination exchange 105 performs a call connection with the destination terminal 107. The home location register 113 collects information on the destination terminal requested by the call to the destination exchange 105.

The home location register 113 determines whether to register a service for the called terminal 107. As a result of the determination of the home location register 113, when the called terminal 107 registers a callable notification service, the home location register 113 stores the calling terminal information requested to be connected to the destination exchange 105. . The calling terminal information is number information about the calling terminal 101.

In step S205, when the called terminal 107 does not respond to the incoming request, for example, when the called party does not ring in the state that the call path is set, or when the called terminal 107 is busy, step S209 The calling terminal 101 ends the call request. However, when the called terminal 107 is called according to the calling request of the calling terminal 101, the call is made between the calling terminal 101 and the called terminal 107 in step S207.

In step S209, the caller terminates the exchange service of the originating exchange 103 and the destination exchange 105 as the call setup fails. The home location register 113 starts a callable notification service and monitors a communication state of the called terminal 107, for example, a device operating state such as a call or the Internet. This is to recognize the communication state for the destination terminal 107 from the destination exchange 105, and detects the wireless Internet or call state that the destination terminal 107 is connected through the destination exchange 105. As in step S211, when the home location register 113 determines the communication state of the called terminal 107 through the destination exchange 105, if the current destination terminal 107 is not communicating, repeat step S211. To continuously monitor the communication state of the called terminal 107.

However, when the home location register 113 determines in step S211 that the called terminal 107 is determined to be busy or using the Internet, it enters step S213. The home location register 113 determines whether the communication state of the called terminal 107 is terminated. As a result of the determination, when the called terminal 107 is in the current communication state, it feeds back to step S211. On the other hand, when the home location register 113 determines that the communication state of the terminating terminal 107 is determined to be terminated, that is, the terminating exchange 105 and the terminating terminal 107 are not establishing a call path If so, the home location register 113 extracts the terminal information for the calling terminal 101 and the terminal information for the called terminal 107.

The home location register 113 generates service indication information for executing the callable notification service together with the terminal information for the calling terminal 101 and the called terminal 107. The home location register 113 requests the calling terminal 101 to set up a call, and the call path is connected to the calling switch 103 where the calling terminal 101 is located. The home location register 113 provides service indication information to the originating exchange 103.

The originating exchange 103 recognizes the service indication information before setting up a call with the originating terminal 101 and, accordingly, transmits the service indication information to the service server 111. The service server 111 requests the terminal information on the terminating terminal 107 to the terminating exchange 105 which is currently connected to the originating exchange 103. In operation S217, the service server 111 receives terminal information on the called terminal 107 and extracts a preset message, that is, a callable notification message for notifying that the called terminal 107 is currently available. . In step S219, the service server 111 transmits the terminal information about the called terminal 107 together with the callable notification message to the calling terminal 101 through the calling switch 103.

As shown in (a) of FIG. 3, the callable notification message may be used by changing a guide message of a caller ID service (CID). For example, by changing the "missed call" comment that is applied in the caller indication service to "callable with 017-123-4567", the calling terminal 101 can notify the called terminal 107 and the available state. On the other hand, as shown in (b) of Figure 3, it is a matter of course that the caller can be notified to the caller using a separate guide message, for example, a short message (SMS) or a multimedia message (MMS).

As such, when the user wants to use a separate guide message, the service server 111 receives the service indication information and then notifies the message server 109 to the message server 109. The message is transmitted to the originating exchange 103 using a short message (SMS) or multimedia message (MMS) channel. Accordingly, the calling terminal 101 receives a call available state with the called terminal 107 through a predetermined guide message.

In the present invention, in transmitting the callable state with the called terminal 107 to the calling terminal 101, a callback function is provided so that a direct call can be made to the called terminal 107 together with a simple guide message. Of course you can. Further, in the communication state of the called terminal 107, when the called terminal 107 is communicating with the calling terminal 101, it will be obvious that the home location register 113 does not execute the callable notification service. .

As described above, the callable notification system of the mobile communication terminal according to the present invention, after the caller makes a call request to the called terminal, when the call is terminated in a state where the call is not made, the communication state of the called terminal (calling By monitoring the communication state with the terminal), after the termination of the communication of the called terminal, the callable notification message is transmitted to the calling terminal, thereby increasing not only the call success rate of the caller but also the functionality of the communication service.

What has been described above is merely an embodiment of the present invention, and is not limited to the embodiment of the present invention, and as claimed in the following claims, without departing from the gist of the present invention, ordinary knowledge in the field to which the present invention belongs. Anyone having the technical spirit of the present invention to the extent that various changes can be made.
