Abstract

PURPOSE: A reserved call system of a portable terminal is provided to request a reserved call of a service provider if a portable terminal of other party cannot receive a call, and to enable the service provider to inform a user that the portable terminal of the other party can receive the call, so that the user can know a call-capable state without repeatedly attempting the call. CONSTITUTION: A user terminal(10) transmits a reserved call request message to the first service provider(20) by operating a key or a menu. If the first service provider(20) senses a call-capable state of other terminal(30) and transmits a message to the user terminal(10), the user terminal(10) reads the message, and informs a user of read contents of the message. If the other terminal(30) cannot receive a call, the first service provider(20) receives a reserved call request message from the user terminal(10), stores telephone numbers of the user terminal and the other terminal(30), and completes the call. When the other terminal(30) can receive the call, the service provider(20) monitors a state of the other terminal(30).

Description

CALL RESERVATION SYSTEM FOR MOBILE TERMINAL AND METHOD THEREOF}

The present invention relates to a reserved call system and method of a mobile terminal, and in particular, when the other party cannot make a call, a reservation call is appropriate for improving the user convenience by enabling a call connection with the user automatically when the other party can make a call. The present invention relates to a reserved call system and method for a portable terminal.

With the spread of portable terminals, calls between portable terminals are increasing rapidly. However, due to the characteristics of the portable terminal, the portable terminal may not be able to make a call. For example, when there is no battery, when the power is turned off, when it leaves the service area, or when there is a call.

The service provider knows the current state of the terminal, so if the call is unsuccessful, the user is informed about the call. In general, the user who made the call is turned off, on the phone, or has left the service area. You can see this.

If the other party fails to talk with the mobile terminal due to the above reason, the call must be repeatedly attempted until the other party receives the call. In most cases, the call is abandoned.

As described above, if the user cannot make a call, the user may leave a voice message or leave a contact number in the voice mail box which is automatically switched while the user is notified of the call.

If the other party does not answer the call may be away from the mobile terminal, in this case it is likely that you can make a call by repeatedly making a call. However, if the phone is turned off due to power consumption, you will not know when the call is available. Also, if you are on a call, you will not know how long to continue the call.

Therefore, when urgent contact is required or when a call must be made, inconvenience of the user due to continuous call attempt becomes great.

As described above, a call using a conventional mobile terminal may leave a message or repeatedly attempt to make a call when the other party's mobile terminal is turned off, has left the service area, or is busy. Wasting time and effort was a heavy problem.

In view of the above problems, the present invention provides the user with a request for a reserved call to the service provider when the counterpart mobile terminal is incapable of communication, and the service provider notifies the user when the counterpart mobile terminal becomes available for communication. An object of the present invention is to provide a reserved call system and method for a portable terminal capable of improving the number of mobile terminals.

The present invention for achieving the above object, and the other terminal for transmitting a predetermined signal when the call possible; A user terminal having a function of transmitting a reservation call request signal and receiving a message indicating that the other party is available and informing a user thereof; Receiving a reservation call request signal from the user terminal to monitor the availability of the other terminal that is currently incapable of communication, and comprises a service provider that transmits a message indicating the availability of the other party to the user terminal when available It is done.

The service provider may be composed of different service providers subscribed to each terminal, in which case the service providers share information on whether to make a reservation call request, a user phone number, a counterpart phone number, and the availability of the counterpart terminal. It is done.

In addition, the present invention comprises the steps of a user attempting a call to the other terminal using the terminal; Transmitting, by the user terminal, a reserved call request signal to a service provider according to a user selection when the counterpart terminal is incapable of talking in the step; Receiving a call request signal, the service provider monitoring a state of a counterpart terminal until a call is possible; Transmitting a call enabled message to a user terminal when the counterpart terminal becomes available for calling in the step; The user terminal receiving the call possibility message from the step may include informing the user of the call availability state of the counterpart terminal.

An embodiment of the reserved call system and method of the present invention as described above will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an embodiment of the present invention, the member itself is the same as the configuration for general mobile terminal communication as shown. However, it is worth noting that the function and behavior of each member is different.

First, the user terminal 10 should be able to transmit a reservation call request message to the first service provider 20 through a predetermined menu or key operation, and then the first service provider 20 calls the counterpart terminal 30. When the possible state is detected and the contents are transmitted in a specially configured message to the user terminal 10, the contents should be read and notified to the user. Therefore, the user terminal 10 of the present invention needs to add a program for providing a reserved call service.

On the other hand, since the counterpart terminal 30 may perform only the functions of the general conventional terminal, it does not need to be particularly changed in order to implement the present invention, thereby increasing the compatibility of the present invention.

When the first service provider 20 cannot make a call to the counterpart terminal 30, the first service provider 20 receives a predetermined call request message from the user terminal 10, and thus receives the reserved call from the user terminal 10. After notifying the fact, the phone number of the counterpart terminal 30 and the user terminal 10 is stored, and the call with the user terminal 10 ends. Then, the status of the counterpart terminal 30 is continuously checked, and the status of the counterpart terminal 30 is either a terminal unavailable (power off or out of service area) or a call. That is, the reserved call is not used when the counterpart terminal 30 is in a callable state but the counterpart does not receive the call.

Since the counterpart terminal 30 continuously communicates with the base station when the counterpart terminal 30 becomes available, the service provider 20 may monitor the state of the counterpart terminal 30. That is, when the call is available (power-on or return to the service area) in a call unavailable state (power off or out of service area), the counterpart terminal 30 transmits a registration signal to an adjacent service provider 20 base station. Therefore, the return to the available state can be known. In addition, when the counterpart terminal 30 is busy and the call ends, the counterpart terminal 30 transmits a release order signal to the base station, thereby using the signals from the counterpart terminal 30. 20 may recognize that the counterpart terminal 30 has become available for a call.

The service provider 20 confirms the call availability state of the counterpart terminal 30 through the above method and transmits a message indicating this to the user terminal 10. For example, a feature notification message is sent, which consists of a header part indicating the message type and a text part with the actual message. Accordingly, the user terminal 10 determines that the currently received message is a result of the reserved call service based on the corresponding message type and the parameters included therein. Subsequently, the subsequent text message includes a predetermined special character, and after that, by listing the telephone numbers of the counterpart terminal 30 so that the user terminal 10 recognizes this and informs the user, the counterpart phone number Can be stored for currency purposes.

In summary, the user terminal 10 that has received the notification message including the phone number of the counterpart terminal 30 recognizes that a call with the requested counterpart is possible as a result of the reserved call service, and the user terminal 10 While displaying on the display unit, the counterpart terminal 30 is notified to the user through a bell or vibration. The user may confirm this and press a call key to make a call with the counterpart terminal 30.

Here, various modifications are possible, and the user portable terminal 10 receiving the result of the reserved call service may generate a ring tone different from the general ring tone while displaying the requested counterpart phone number.

2 is a further enlarged embodiment of the present invention shown in FIG. 1, and the present invention is applied when the service providers 20 and 25 subscribed to the user terminal 10 and the counterpart terminal 30 are different. The configuration is shown.

The basic operation is similar to that of FIG. 1 described above, but there is a prerequisite that data exchange for a reserved call service should be performed between the first service provider 20 and the second service provider 25. This should be an agreement between service providers for the present invention. In the technical aspect, since various services are already provided regardless of service providers, the present invention requiring simple data exchange can use a known technique.

The first service provider 20 only needs to transmit information indicating that the second service provider 25 is a reserved call service and the phone number of the counterpart terminal 30, and the second service provider 25 receives the received information. The counterpart terminal 30 is monitored using the information, and when the counterpart terminal 30 becomes available for call, the first information includes information indicating that the reservation call service is the result, callable information, and phone number of the counterpart terminal 30. What is necessary is just to be able to transmit to the service provider 20.

As described above, the present invention may be practiced through changing the functions of the user terminal 10 and the service providers 20 and 25, and specific service methods and technical application methods may be variously changed. Note that it may be encompassed by the present invention.

Figure 3 is a flow chart showing the sequence of an embodiment of the present invention, as shown in the relatively simple method.

First, when a user attempts to make a call with a counterpart terminal using a user terminal and makes a successful call, the user makes a call. If the user generates a predetermined call request signal to the service provider base station through a menu or key operation.

After receiving the reservation call request signal, the service provider memorizes the telephone number of the user terminal and the telephone number of the counterpart terminal, terminates the connection with the user terminal, and waits until the status of the counterpart terminal becomes available.

When the status of the counterpart terminal becomes available, a predetermined signal is transmitted to the service provider base station (registration, release order signal, etc.), and thus the service provider who receives the signal transmits a notification message to the user terminal.

The notification message includes the other party's phone number and includes parameters for identifying that the user terminal is the result of the reserved call service.

Upon receiving the notification message, the user terminal displays the corresponding content on the display unit or notifies the user that the counterpart terminal is in a callable state by using a ringtone / vibration function. In this case, the user terminal may store the other party's phone number included in the notification message, and according to an embodiment, may display a name on the phone book for the user's phone number.

The user checks this and presses a call key and attempts to call the other party's phone number stored in the terminal.

As described above, in the reserved call system and method of the present invention, when a counterpart mobile terminal is incapable of making a call, the user requests a reserved call from a service provider through a predetermined key operation, and the service provider is in a state where the counterpart mobile terminal can make a call. In this case, the user can be notified of this by notifying the user of the other party without repetitive call attempts, thereby increasing the call success rate and improving user convenience by eliminating time and effort.
