Abstract

PURPOSE: A call reserving and connection service device depending on whether a call is capable is provided to immediately deliver a call to terminals of a receiver and an originator through a PCX and a call reservation/connection service server if the terminal of the receiver is converted into a call-capable state, thereby automatically connecting the call. CONSTITUTION: A PCX(130) receiving a call from an originator terminal(100) retrieves a database of an HLR(170) to sense a location of a receiver terminal(120), and starts a call reservation/connection service if the location of the receiver terminal(120) is not sensed. A call reservation/connection service server(140) registers receiving/originating data including telephone numbers of the originator terminal(100) and the receiver terminal(120) in a database. To the PCX(130), the call reservation/connection service server(140) periodically delivers a virtual call for requesting to sense whether the call is capable in the receiver terminal(120). The service server(140) delivers a real call to the originator terminal(100) if the call is capable in the receiver terminal(120) when data in accordance with a sensed location of the receiver terminal(120) is inputted in the database of the HLR(170). If a send button is pressed in the receiver terminal(120), the PCX(130) couples the real call with the virtual call.

Description

Method and device of call reservation and connection service according to call availability detection {METHOD AND DEVICE FOR COMMUNICATION RESERVE AND CONNECTION SERVICE ACCORDING TO DETECTION OF CONNECTABILITY}

The present invention relates to a method and apparatus for call reservation and connection service, and more particularly, when a called party's wireless terminal is changed into a callable state when the called party's wireless terminal is in a disabled state. A method and apparatus for a service that calls all called parties to establish automatic call reservation and connection.

A mobile communication service refers to an individual using a portable terminal (a mobile phone, a mobile phone, a PDA including its function, etc., which may be referred to as a mobile station for a base station, a relay station, etc.) regardless of place. It is a service that can easily perform voice and data communication.

In the mobile communication service, when a caller enters an area where the called party cannot talk, the call with the caller becomes impossible. Of course, in recent years, due to the installation of a high-performance switching server and the widespread use of relay antennas, the call sensitivity and sound quality are highly improved as well as the area where communication is not available.

However, no matter how highly the quality of the mobile communication is improved, a situation in which the called party cannot make a call may still occur due to the personal circumstances of the called person or the special place situation of the called party. For example, in an environment where the mobile phone cannot be used within a certain area, such as when the called party is on an aircraft or inside a laboratory using high frequency (in this case, the air mode is generally referred to as Device to block the reception of the mobile phone), and when the called party needs to turn off the mobile phone, such as during a meeting in the office, in class at school, or watching a movie in a theater. There is still a situation where the called party cannot call.

Conventionally, as a service for such a call impossible situation, as shown in FIG. 1, although the caller terminal 1 has made a call for a call call to the called party terminal 2, the called terminal is powered off. If the call is in a call-free state, such as when the call is in a busy state or in a region outside the call service right, the calling call of the calling terminal is one of additional services provided by the service provider's network 3 immediately or after a predetermined time. (VMS; Voice Mailing System) or an additional service database 5 is automatically connected. Subsequently, when the caller terminal is connected to the voice mailbox of the service provider, the user of the caller terminal may leave a call message or a voice message along with the telephone number to be contacted by the called party terminal according to the voice mail announcement. And, the information left by the calling party terminal subscriber is stored in the service provider's database, and when the called terminal is switched to the available state, the location of the called terminal is registered in the home location register (HLR). The content is displayed on the called terminal. Therefore, the user of the called terminal can check the voice or text message recorded in the voice mailbox, and attempt to call the caller. 2 is a flowchart illustrating such a process.

Catch Call (service name) currently being serviced in South Korea uses the above conventional technology, and the telephone number received during the moment when the called terminal enters a callable area or the terminal is powered on Is being sent as a text message. When the service determines that a call to the called party's terminal is impossible, after storing the incoming / outgoing call data on the service server, when the called party's terminal is converted into a callable state, the service stores the incoming call data as a text message to the called party's terminal. It is delivered to the back.

In addition, as a patent application that discloses similar technical contents, as shown in Fig. 3, the 'callable notification method' described in the Republic of Korea Patent Publication No. 10-2000-37833, the location of the called party's terminal When is registered in the location register, the technical content is disclosed that delivers a text message indicating that the location of the receiver terminal is registered in the location register to the calling party terminal, not the destination terminal, and is similar to the prior art described above. .

By the way, in the above conventional services, the caller or the recipient who received the text message is inconvenient to select the phone number of the caller written in the text message and make a call.

In addition, the caller wants to make a call with the called party as soon as possible, but according to the conventional service, if the called party does not answer the caller after receiving a text message containing the caller's phone number, the caller may be a useless service. There is nothing else.

Accordingly, the present inventors have devised a method and apparatus for a call connection service that automatically connects a call with a caller as soon as the called party is switched to the available state in view of the problems of the conventional service.

An object of the present invention is to automatically send a call to the terminal of the calling party and the called party through the call reservation / connection service server and mobile switching system as soon as the called party in the non-call state is switched to the available state It is to provide a method and apparatus of a call connection service to enable a connection.

Another object of the present invention is to provide a method and apparatus for making an automatic call connection service when a service applicant is a caller.

Still another object of the present invention is to provide a method and apparatus for making an automatic call connection service when a service applicant is a called party.

In order to achieve the above object, a basic configuration of a method and apparatus for a call reservation and connection service according to a call availability detection according to the present invention will be described below.

The method of the call reservation / connection service according to the first aspect (claim 1) of the present invention, for establishing a call connection with the calling party terminal after the incapable state of the called party terminal, the call according to the detection of the availability of the called terminal As a method of reservation / connection service, the mobile switching system (PCX), which has received a call call from the calling party's terminal, searches the database of the home location register (HLR) to detect the location of the called party's terminal. Initiating a call reservation / connection service when it is determined that Registering the incoming / outgoing data including the telephone number of the calling party terminal and the telephone number of the called party terminal in a database of the call reservation / connection service server according to the start of the call reservation / connection service server; Sending a virtual call to the mobile switching system from the call reservation / connection service server to request a call detection signal of the called party terminal at predetermined intervals; When the call reservation / connection service server determines that the called party's terminal is available for call, when the data corresponding to the location of the called party's terminal is input to the database of the home location register connected with the mobile switching system as a response to the virtual call transmission, the caller's terminal side is determined. Sending a real call towards; When the call connection button on the calling party terminal and the called party terminal is pressed, the mobile switching system includes a step of combining a real call destined for the calling party terminal and a virtual call destined for the called party terminal (claim 1).

In the call reservation / connection service method according to the first aspect of the present invention, the service applicant is a caller, and a service operator is a call reservation / connection service server (hereinafter referred to as a service server).

The service server is combined with a mobile switching system (PCX) and a voice mail system (VMS), and the mobile switching system (PCX) includes a home location register (HLR). It should be noted that the voicemail system is not necessarily a system for providing a voice service but a system including a system for providing services through the wired / wireless Internet. In addition, in the practical application of the present invention, a PCX end system for communicating with a service server and controlling a mobile switching system should be installed in the mobile switching system, but it will be described as being included in the mobile switching system (PCX). . This point is assumed to be the same throughout this specification.

First, when a caller, who is a service applicant, makes a call to a called party terminal through a calling party terminal, the mobile communication system (PCX) of the mobile communication provider on the called party terminal receives the call. The mobile switching system searches the database of the home location register (HLR) to detect the location of the called party's terminal. When the called terminal is powered off or in an area where radio waves cannot reach, the mobile switching system needs to communicate with the called party at a predetermined time interval. The relay antenna fails to communicate with the called terminal. Thus, the location of the current called party's terminal cannot be registered in the database, and it is determined that the location detection of the called party's terminal is impossible, and this is regarded as the incapable state of the called party's terminal, and the call reservation / connection service is started (service start). step).

In this case, the caller may be selected whether or not to initiate a call reservation / connection service through a voicemail service provided by a voicemail server (VMS). In a general voicemail service, only 1) call and 2) text message transmission can be selected, but the voicemail server according to the present invention receives 3) call reservation / connection service in addition to 1) phone call and 2) text message transmission menu. It further includes a menu that can be.

Upon initiation of the call reservation / connection service, the service server registers incoming and outgoing data in a database that includes itself (data registration step). The incoming and outgoing data registered in the database of the service server should include at least the telephone number of the calling terminal and the telephone number of the called terminal.

In addition, incoming and outgoing data registered in the database of the service server may include a) a call reservation period, b) number of call connection attempts, and c) respective priorities for a plurality of called terminal.

The service server makes and receives calls such as the phone number of the calling party terminal and the called party's phone number registered in the database, a) call reservation period, b) number of call connection attempts, and c) each priority for a plurality of called party terminals. The data is used to send a virtual call to the called party and a real call to the calling party.

First, the service server transmits a virtual call for requesting a call availability detection signal of the called party's terminal to the mobile switching system every predetermined period (called party). The predetermined period may be set to 5 seconds, 10 seconds, or 1 minute, but the shorter the period, the shorter the period of the mobile communication operator (processing speed of the service server, processing speed of the mobile switching system, battery consumption of the called party's terminal, etc.). Consideration should be given to the burden.

A virtual call is used to block a call from another terminal in addition to requesting a call detection signal. For example, while the virtual call is being sent to the called party, even if a call from a third party enters, the call is blocked by the virtual call.

Next, in response to the virtual call transmission from the service server, the mobile switching system tries to track the location of the called terminal. That is, the mobile switching system retrieves data according to the position detection of the called terminal in the database of the home location register connected thereto. At this time, if data on the called party's terminal is input to the home location register, the called party's terminal determines that the call is possible, and informs the service server. As a result, the service server sends the real call toward the calling party terminal while maintaining the virtual call directed to the called party's terminal (caller sending step). In this case, instead of transmitting the real call toward the calling party terminal while maintaining the virtual call toward the called party terminal, the real call may be sent first to the calling party terminal and the virtual call may be sent toward the called party terminal. It is also possible to simultaneously send a call to both sides (the calling terminal and the called terminal) and to connect the calls of both sides when the call connection button of both sides is pressed.

On the other hand, the transmission of the virtual call and the real call is made according to the incoming / outgoing call data mentioned above. That is, within the call reservation period, when it is determined that the called terminal is available for call, a virtual call or a real call is sent. In addition, the real call is made as many times as the number of call connection attempts. In the case where there are a plurality of called party terminals which are switched to the available call state, the priority may be set. For example, if the number of call connection attempts has elapsed while transmitting a real number toward the calling party terminal while maintaining the virtual call directed to the called party terminal, the priority of the called party terminal is given priority to each of the plurality of called party terminals. You can change to the lowest of the ranks. Through this process, call connection attempts for a plurality of called party terminals may be repeated.

Finally, when both the call connection buttons on the calling terminal and the called terminal are pressed, the service server instructs the mobile switching system to combine the actual call destined for the calling terminal and the virtual call destined for the called terminal (call combining step). By combining the real call and the virtual call, the effect of the real call call from the calling party is directed to the called party.

Call reservation / connection service method according to a second aspect of the present invention (claim 5), the call reservation according to the detection of the availability of the caller terminal, for establishing a call connection with the caller terminal after the incapable state of the called party terminal occurs As a method of connection service, when a mobile switching system receiving a call call from a calling party terminal searches the database of the home location register to detect the location of the called party terminal, it is determined that the calling terminal cannot detect the location of the called party terminal. Initiating a connection service; In accordance with the start of the call reservation / connection service, an incoming / outgoing data including the telephone number of the calling party terminal and the telephone number of the called party terminal is registered in a database of the call reservation / connection service server and transmitted to the mobile switching system; Receiving, by the mobile switching system, the incoming and outgoing call data registered from the call reservation / connection service server, and determining whether the called party is available by calling the data according to the detection of the location of the called party's terminal in a database of the home location register connected to the mobile switching system; ; When it is determined in the determining step that the called party terminal is available for calling, the mobile switching system sending a virtual call toward the called party terminal; When it is determined in the determining step that the called party terminal is available for calling, the mobile switching system sending a real call toward the calling party terminal; When the call connection button is pressed on the calling party terminal and the called party terminal, the mobile switching system includes a step of combining a real call destined for the calling party terminal and a virtual call destined for the called party terminal (claim 5).

In the call reservation / connection service method according to the second aspect of the present invention, the service applicant is a caller, and the service operator is a mobile switching system, which is combined with a call reservation / connection service server (hereinafter referred to as a service server). Although the method according to the first aspect of the present invention differs in that the service operating subject is expressed differently, it may be considered that both operating entities are substantially the same in consideration of the coupling structure.

First, when a caller, who is a service applicant, makes a call to a called party terminal through a calling party terminal, the mobile communication system (PCX) of the mobile communication provider on the called party terminal receives the call. The mobile switching system searches the database of the home location register (HLR) to detect the location of the called party's terminal. When the called terminal is powered off or in an area where radio waves cannot reach, the mobile switching system needs to communicate with the called party at a predetermined time interval. The relay antenna fails to communicate with the called terminal. Thus, the location of the current called party's terminal cannot be registered in the database, and it is determined that the location detection of the called party's terminal is impossible, and this is regarded as the incapable state of the called party's terminal, and the call reservation / connection service is started (service start). step).

In this case, the caller may be selected whether or not to initiate a call reservation / connection service through a voicemail service provided by a voicemail server (VMS). In a general voicemail service, only 1) call and 2) text message transmission can be selected, but the voicemail server according to the present invention receives 3) call reservation / connection service in addition to 1) phone call and 2) text message transmission menu. It further includes a menu that can be.

Upon initiation of the call reservation / connection service, the service server registers incoming and outgoing data in a database that includes itself (data registration step). The incoming and outgoing data registered in the database of the service server should include at least the telephone number of the calling terminal and the telephone number of the called terminal. The registered incoming and outgoing data is transmitted to the mobile switching system.

The incoming / outgoing data registered in the database of the service server and transmitted to the mobile switching system may include a) a call reservation period, b) number of call connection attempts, and c) respective priorities for a plurality of called terminal. The mobile switching system may include the phone number of the calling party terminal and the called party's telephone number registered in the database, a) call reservation period, b) number of call connection attempts, and c) respective priorities for a plurality of called party terminals. Using the incoming and outgoing data, a virtual call is sent to the called party and a real call is sent to the calling party.

Subsequently, the mobile switching system receives the incoming / outgoing call data registered from the call reservation / connection service server and determines whether or not data corresponding to the position detection of the called terminal is input to the database of the home location register connected to the mobile switching system. 5 seconds, 10 seconds or 1 minute). The position of the called party terminal is detected, and it is determined that the called party terminal is available for call (call availability determination).

Next, when it is determined in the determination step that the called party terminal is available for calling, the mobile switching system sends out a virtual call toward the called party terminal and sends a real call toward the calling party terminal (called party and caller sending step). The order of virtual call sending and real call sending may be made first, or at the same time. However, since it is most efficient and quick to send a real call to the caller terminal while maintaining the virtual call at the moment when it is determined that the call of the called terminal is possible, it is preferable.

It is also the same as the first aspect that sending out virtual calls and real calls is made according to the incoming / outgoing call data mentioned above. That is, within the call reservation period, when it is determined that the called terminal is available for call, a virtual call or a real call is sent. In addition, the real call is made as many times as the number of call connection attempts. In the case where there are a plurality of called party terminals which are switched to the available call state, the priority may be set. For example, if the number of call connection attempts has elapsed while transmitting a real number toward the calling party terminal while maintaining the virtual call directed to the called party terminal, the priority of the called party terminal is given priority to each of the plurality of called party terminals. You can change to the lowest of the ranks. Through this process, call connection attempts for a plurality of called party terminals may be repeated.

Finally, as the call connection buttons on the calling party terminal and the called party terminal are pressed, the mobile switching system combines the real call destined for the calling party terminal and the virtual call destined for the called party terminal (call combining step). By this combination, the effect of making a call call from the calling terminal toward the called terminal occurs.

Call reservation / connection service method according to a third aspect of the present invention (claim 9), the call reservation according to the detection of the availability of the caller terminal, for establishing a call connection with the caller terminal after the incapable state of the called party terminal occurs CLAIMS 1. A method of a connection service, comprising the steps of: receiving a command for starting a call reservation / connection service from a called terminal through a voicemail service provided in a voicemail server connected to a called terminal; Determining, by the mobile switching system that receives a telephone call from the calling party terminal, a search of the database of the home location register to detect the location of the called party terminal that the called party's location cannot be detected; Registering incoming and outgoing data including a telephone number of a calling party terminal and a telephone number of a called party terminal in a database of a call reservation / connection service server coupled with a voicemail server and a mobile switching system; Transmitting, from the call reservation / connection service server to the mobile switching system, a call for a call detection signal of the called party's terminal at predetermined intervals; The call reservation / connection service server is directed to the called party's terminal when it is determined that the called party's terminal is available for call because data corresponding to the location of the called party's terminal is input to the database of the home location register connected to the mobile switching system in response to the call out. Transmitting a virtual call toward the calling party's terminal while maintaining the true call; When the call connection button on the calling party terminal and the called party terminal is pressed, the mobile switching system includes a step of combining a virtual call destined for the calling party terminal and a real call destined for the called party terminal (claim 9).

In the method of call reservation / connection service according to the third aspect of the present invention, a service applicant is a called party, and a service operator is a call reservation / connection service server (hereinafter, referred to as a service server).

Since the functions and roles of each component in service operation are the same as those described in the first and second aspects of the present invention, only the differences will be described below.

First, an application or start command for the service is input from the called party's terminal. That is, the caller receives a start command of the call reservation / connection service through a voicemail service provided by a voicemail server connected to the called party's terminal from the called party's terminal (starting command receiving step). It should be noted that the voicemail server and the voicemail service do not mean only the voice processing server and the service but also include an application via the wired / wireless internet.

The called party, who is a service applicant, initiates call reservation / connection service and then turns off the called party's terminal or enters a dead zone if necessary, and then receives a phone call from the calling terminal. As a result of searching the database of the home location register to detect the location of the called party terminal, the switching system determines that the called party location cannot be detected because there is no called party location data (non-call determination step). If it is possible to detect the location of the called party, even if the application and the start of the service is made, so as to directly connect the call from the caller to the called party.

Next, the call reservation / connection service server (service server) associated with the voicemail server and the mobile switching system registers incoming / outgoing data in its own database (data registration step). The incoming and outgoing data shall include the telephone number of the calling party terminal and the telephone number of the called party terminal. The incoming / outgoing data registered in the service server's database may include a) call reservation period, b) number of call connection attempts, and c) respective priorities for a plurality of called party terminals, the function of which is a first aspect. And the second aspect.

Subsequently, the service server sends a call to the mobile switching system for every call (eg, 5 seconds, 10 seconds, or 1 minute) to request a call detection signal of the called terminal.

Next, the service server sends the caller's terminal to the caller's terminal when it determines that the called party's terminal is available because data corresponding to the location of the called party's terminal is input to the database of the home location register connected with the mobile switching system in response to the call out. The virtual call is sent out (caller sending step). In this case, the virtual call transmission to the calling party terminal is preferably carried out while maintaining the real calling toward the called party's terminal (because the third party's call to the called party's terminal can be blocked while maintaining the real calling toward the called party's terminal). ), Virtual call transmission to the calling party terminal may be made after newly transmitting a real call to the called party terminal, and call transmission may be performed simultaneously or sequentially.

Finally, as the call connection buttons on the calling party terminal and the called party terminal are pressed, the virtual call destined for the calling party terminal in the mobile switching system and the real call destined for the called party terminal are combined (call combining step). Thus, the call call from the called terminal is directed to the calling terminal.

As a result according to the third aspect of the present invention, the first sender becomes a called party and the first called party becomes a calling party. This is to avoid charging a telephone fee to the first caller who is not a subscriber of the service.

Call reservation / connection service method according to the fourth aspect of the present invention (claim 12), the call reservation in accordance with the detection of the availability of the caller terminal, for establishing a call connection with the caller terminal after the incapable state of the called party terminal occurs CLAIMS 1. A method of a connection service, comprising the steps of: receiving a command for starting a call reservation / connection service from a called terminal through a voicemail service provided in a voicemail server connected to a called terminal; Determining, by the mobile switching system that receives a telephone call from the calling party terminal, a search of the database of the home location register to detect the location of the called party terminal that the called party's location cannot be detected; Registering incoming and outgoing data including the telephone number of the calling party terminal and the telephone number of the called party terminal in a database of a call reservation / connection service server coupled with the voicemail server and the mobile switching system and transmitting to the mobile switching system; Receiving, by the mobile switching system, the incoming and outgoing call data registered from the call reservation / connection service server, and determining whether the called party is available by calling the data according to the detection of the location of the called party's terminal in a database of the home location register connected to the mobile switching system; ; When it is determined in the determining step that the called terminal is available for communication, the mobile switching system sending a virtual call toward the calling terminal; When it is determined in the determination step that the called party terminal is available for calling, the mobile switching system sending a real call toward the called party terminal; When the call connection button is pressed on the calling party terminal and the called party terminal, the mobile switching system includes a step of combining the virtual call destined for the calling party terminal and the real call destined for the called party terminal (claim 12).

In the call reservation / connection service method according to the fourth aspect of the present invention, a service applicant is a called party, and a service operator is a mobile switching system, which is combined with a call reservation / connection service server (hereinafter referred to as a service server).

Since the functions and roles of each component in the service operation are the same as those described in the first, second and third aspects of the present invention, only the differences will be described below.

First, a request for application and start of the service is received from the called terminal. That is, the caller receives a start command of the call reservation / connection service through a voicemail service provided by a voicemail server connected to the called party's terminal from the called party's terminal (starting command receiving step). The voicemail server and the voice service are not necessarily limited to voice, and of course, input of a start command through a wired / wireless internet is also included.

Subsequently, when there is a telephone call from the calling party terminal, the recipient side mobile switching system searches the database of the home location register to detect the location of the called party terminal, and if the data on the location of the called party terminal is not registered, detects the called party's location. Determines that the call is impossible (a call impossible determination step). Although the service is commanded by the receiver terminal, the service is started when the receiver terminal is powered off or enters the non-callable area.

Next, incoming / outgoing data is registered in a database of a call reservation / connection service server coupled with the voicemail server and the mobile switching system, and this data is transmitted to the mobile switching system (data registration step). The incoming and outgoing data should of course include the telephone number of the calling party terminal and the telephone number of the called party terminal.

Then, the mobile switching system receives the registered incoming and outgoing data from a call reservation / connection service server, and data according to the position detection of the called terminal is input to a database of a home location register connected to the mobile switching system so that the called terminal is called. It is determined whether it is possible (call possibility judgment step).

When it is determined in the determination step that the called party terminal is available for calling, the mobile switching system sends a virtual call toward the calling party terminal and sends a real call toward the called party terminal (calling party and called party sending step). The virtual call transmission to the caller terminal and the real call transmission to the caller terminal may be simultaneously performed, or any of these may be made first. However, it is preferable to send a real call directed to the called party's terminal first to block a call from a third party and to maintain the real call while sending a virtual call toward the calling party's terminal.

Finally, when a call connection button is pressed on the calling party terminal and the called party terminal, the mobile switching system combines the virtual call destined for the calling party terminal and the real call destined for the called party terminal (call combining step). The combination produces the same effect as the called terminal making a call to the calling terminal. Thus, the original called party and the sender are interchanged according to the fourth aspect of the present invention. This is to avoid calling charges to callers who are not subscribers.

The device of the call reservation / connection service according to the fifth aspect of the present invention is a call reservation / connection service according to detection of call availability of a called party terminal for establishing a call connection with a calling party terminal after the incapable state of the called party terminal occurs. As a device of

A memory or recording medium in which a service program is stored;

A service device including a call reservation / connection service server for executing a service program in association with a memory or a recording medium,

The call reservation / connection service server depends on the service program,

Initiating a call reservation / connection service when it is determined that the location detection of the called party terminal is impossible; Registering incoming and outgoing data including a telephone number of a calling party terminal and a telephone number of a called party terminal in a database of a call reservation / connection service server; Sending a virtual call to the mobile switching system every predetermined period for requesting a call detection signal of the called terminal; When a call is received from the mobile switching system as a response to the virtual call transmission, when the data according to the detection of the called terminal is input to the database of the home location register connected to the mobile switching system, it is determined that the called terminal can be called. Sending out a clear sound toward it; As the call connection buttons on the calling party terminal and the called party terminal are pressed, the mobile switching system is instructed to combine a real call destined for the calling party terminal and a virtual call destined for the called party terminal.

A fifth aspect of the present invention presents a call reservation / connection service device useful for operating in conjunction with the first and second aspects of the present invention. Therefore, the service applicant is the caller, and the operating subjects of the service are the service server and the mobile switching system. The call reservation / connection service device is a service device including a memory or recording medium in which a service program is stored, and a service server for executing a service program in combination with the memory or recording medium, wherein the service server operates according to the service program. do.

The procedure of the service program has a service start routine, an incoming and outgoing data registration routine, a caller's callout routine, a call availability decision routine, a caller's callout routine, and a call joining routine as described above.

Accordingly, the service server starts the call reservation / connection service when it is determined that the location of the called party's terminal cannot be detected according to the procedure of the service program, and the called party's location detection impossible determination output moves to the called party's side when calling from the caller. The switching system may be configured by receiving as input that the location data of the called terminal is not registered in the home location register.

The service server then registers the incoming and outgoing data including the telephone number of the calling party terminal and the telephone number of the called party terminal in the database. The incoming and outgoing data may include a call reservation period, number of call connection attempts, and respective priorities for a plurality of called party terminals, in addition to the calling party and the called party's phone number, and the incoming and outgoing data is an exchange or server of a caller or a mobile carrier that is a service applicant. Based on data from

Subsequently, the program of the service server causes the server to send a virtual call to the mobile switching system to request a call detection signal of the called terminal at predetermined intervals. Here, the predetermined period may be 5 seconds, 10 seconds, or 1 minute or more, and the shorter the cycle, the more operator resources of the entire system are consumed, so it should be determined in consideration of this.

The program of the service server may receive a response from the mobile switching system that the data of the receiver terminal is input to the database of the home location register connected to the mobile switching system as a response to the virtual call transmission, thereby determining that the called terminal is available. At the time, the service server causes the mobile switching system to send a clear call toward the calling party terminal.

Finally, upon receiving an input that the call connection button is pressed on the calling party terminal and the called party terminal, the program of the service server instructs the mobile switching system to combine the real call to the calling party terminal and the virtual call to the called party terminal. Call calls from the calling terminal to the called terminal can be realized. Since the procedure of the program for operating the service server is the same as the first and second aspects of the present invention, the duplicate description thereof will be omitted.

The device of the call reservation / connection service according to the sixth aspect of the present invention is a call reservation / connection service according to whether a called party's call is available to establish a call connection with a caller terminal after a call incapacity state occurs. As a device of

A memory or recording medium in which a service program is stored;

A call reservation / connection service server that executes a service program in combination with a memory or a recording medium;

A sixth aspect of the present invention presents a call reservation / connection service device useful for operating in conjunction with the third and fourth aspects of the present invention. Thus, the service applicant is the receiver, and the operating entities of the service are the service server and the mobile switching system.

The call reservation / connection service device is a service device including a memory or recording medium in which a service program is stored, and a service server for executing a service program in combination with the memory or recording medium, wherein the service server operates according to the service program. do.

The procedure of the service program has a service start command reception routine, a call impossible reception routine, an incoming and outgoing data registration routine, a caller's dispatch routine, a call availability decision routine, a caller's dispatch routine, and a call joining routine as described above.

Therefore, the service server first receives a service start command from the called party terminal according to the procedure of the service program. That is, the program of the service server receives from the called party's terminal that it receives an input of a call reservation / connection service start command from the called party's terminal through the voicemail service provided by the voicemail server. It should be noted that the voice mailbox server and its services are not necessarily limited to voice-related services, but also include a start command input by wired / wireless Internet.

Subsequently, the mobile switching system receiving the telephone call from the calling party terminal searches the database of the home location register to detect the location of the called terminal, and the program of the service server is informed that the called party's location cannot be detected as a result. As a result, since it is confirmed that the called party's terminal becomes incapable of calling after the called party's service application, the call reservation / connection service server can take the following procedure.

The program of the service server notified of the location detection registers the incoming / outgoing data including the telephone number of the calling party terminal and the telephone number of the called party terminal in the database of the call reservation / connection service server. The incoming and outgoing data may include a call reservation period, number of call connection attempts, and respective priorities for a plurality of called party terminals, in addition to the calling party and called party's phone number, and the incoming and outgoing data may be a switching device of a called party's terminal or service provider, or Based on data from the server.

Subsequently, the program of the service server sends the mobile switching system a real call for requesting a call detection signal of the called party's terminal every predetermined period (for example, 5 seconds, 10 seconds, or 1 minute or more).

Next, when the data according to the detection of the location of the called terminal is input to the database of the home location register connected with the mobile switching system as a response according to the call transmission, the program of the service server is received. The virtual call is sent toward the calling party terminal.

Finally, upon receiving an input that the call connection button on the calling terminal and the called terminal is pressed, the mobile switching system is instructed to combine the virtual call destined for the calling terminal with the real call destined for the called terminal, thereby transferring the call from the calling terminal to the called terminal. Inbound call calls can be realized. Since the procedure of the program for operating the service server is the same as that of the third and fourth aspects of the present invention, duplicate description thereof will be omitted.

Hereinafter, with reference to the drawings will be described the present invention according to each embodiment.

(First embodiment)

4 is a block diagram showing a call reservation / connection service method according to the present invention, Figure 5 is a block diagram showing a first embodiment of a call reservation / connection service method according to the present invention, Figure 6 is a call according to the present invention A flowchart illustrating a first embodiment of a reservation / connection service method.

In Fig. 4 showing the overall outline of the call reservation / connection service, a caller terminal 100, a caller terminal 120, a caller-side service communication network 110, a mobile switching system 130, a call reservation / connection service server 140 are shown. , Base station 150, voicemail server 160, and home location register 170 are shown. The home location register 170, the mobile switching system 130, the call reservation / connection service server 140, and the voicemail server 160 are organically coupled units.

Here, the service applicant is a user of the caller terminal 100, and the service operator is a call reservation / connection service server 140 (hereinafter abbreviated as a service server). In general, the caller terminal 100 is a subscribed service. When a call is made toward the called party terminal 120 through the communication network 110, the mobile switching system 130 faces the position of the called party terminal 120 registered in the home location register 170 through the base station 150. By calling, the normal call is connected.

However, when the mobile switching system 130 receiving a call call from the calling party terminal 100 searches the database of the home location register (HLR) to detect the location of the called party terminal 120 (S100, S110), the called party If the power of the terminal 120 is off or in an area where radio waves cannot be reached, since the location of the current receiver terminal cannot be registered in the database of the home location register 170, the position detection of the called terminal 120 is impossible. It is determined that this is considered to be incapable of the called terminal 120, the call reservation / connection service is started (S120). In response to the call reservation / connection service being started, the service server 140 registers incoming and outgoing data in a database that includes itself (S130). The incoming and outgoing data registered in the database of the service server 140 should include at least the telephone number of the calling party terminal 100 and the telephone number of the called party terminal 120. The service server 140 transmits a virtual call to the mobile switching system 130 to request a call availability detection signal of the called party terminal 120 at predetermined intervals. While the virtual call is being sent to the called party 120, even if a call from a third party enters, the call is blocked by the virtual call. In response to the virtual call transmission from the service server 140, the mobile switching system 130 retrieves data according to the position detection of the called party terminal 120 in the database of the home location register 170, and transmits the data to the home location register 170. When data for the called party terminal 120 is input, the called party terminal 120 determines that the call is possible and informs the service server of the call (S140, S150, and S160). Accordingly, the service server 140 transmits a real call toward the caller terminal 100 while maintaining the virtual call toward the called party terminal 120 at that moment (S170). At this time, instead of sending a real call toward the caller terminal 100 while maintaining the virtual call toward the called party terminal 120, the call is first sent to the caller terminal 100 side and the called party terminal 120 You may send a virtual call towards. In addition, it is also possible to simultaneously send a call to both sides (caller terminal and called party terminal), and to connect the calls of both sides when the call connection button of both sides 100 and 120 is pressed.

In addition, when the called party terminal 120 is switched to the available state, it is determined whether the call connection button of the calling party terminal 100 or the called party terminal 120 is pressed within a predetermined time (for example, 30 seconds) (S275). If it is not pressed within the time, the number of call connection attempts of the incoming / outgoing data is increased by one, and the changed data is newly registered as the incoming / outgoing data of the database of the service server 140 (S230). When the call connection button of the calling party terminal 100 or the called party terminal 120 is pressed within the predetermined time, the waiting guidance message is sent to the calling party terminal 100 or the called party terminal 120 that first presses the call connecting button (S280). When all the call connection buttons of (100,120) are pressed, the caller's side is combined with the caller's virtual call.

The service server 140 may transmit a waiting guidement to the terminal of the person who first pressed the call connection button among the caller 100 or the caller 120. The waiting announcement may be set to, for example, "Please wait for the called party to answer the call." Finally, when both the call connection buttons at the caller terminal 100 and the caller terminal 120 are pressed, the service server 140 is connected to the caller terminal 100 from the mobile switching system 130 and the caller terminal ( Instructions for joining the virtual call directed to 120 (S190). By combining the real and virtual calls, there is an effect that the real call call from the caller terminal 100 is directed to the called party terminal 120.

On the other hand, in the start of the call reservation / connection service, as shown in the flow chart shown in Figure 7, the caller selects whether to start the call reservation / connection service through the voicemail service provided by the voicemail (VMS) server 160 I can receive it. In a general voicemail service, only 1) call and 2) text message transmission can be selected, but in the present invention, the voicemail server 160 has 3) call reservation / connection service in addition to 1) phone call and 2) text message transmission menu. It further includes a menu to be selected. The service server 140 connects the call from the caller 100 to the voicemail server 160 when the mobile switching system 130 does not know the location of the called party terminal 120. When the voicemail server 160 receives the 3) call reservation / connection service, the service is started.

Fig. 13 shows an example of incoming and outgoing data registered in the database of the service server. For example, the service server may include a telephone number of a calling party terminal and a telephone number of a called party terminal, a call reservation period, a number of call connection attempts, and c) respective priorities for a plurality of called party terminals. By using the incoming and outgoing data, a virtual call can be sent to the called party and a real call can be sent to the calling party. Sending the virtual call and the real call is made according to the incoming / outgoing call data mentioned above. For example, within the call reservation period of FIG. 13, when it is determined that the called terminal is available for call, a virtual call or a real call is made. In addition, the real call is made as many times as the number of call connection attempts. In the case where there are a plurality of called party terminals which are switched to the available call state, the priority may be set. For example, if the number of call connection attempts has elapsed while transmitting a real number toward the calling party terminal while maintaining the virtual call directed to the called party terminal, the priority of the called party terminal is given priority to each of the plurality of called party terminals. You can change to the lowest of the ranks. For example, the third number of connection attempts among the incoming and outgoing data is twice, and the number of connection attempts is greater than that of the first and second data. Since the connection failed despite the number of two connection attempts, the priority is changed to three. Through this process, call connection attempts for a plurality of called party terminals may be repeated.

(2nd Example)

8 is a block diagram illustrating a second embodiment of a call reservation / connection service method according to the present invention, and FIG. 9 is a flowchart illustrating a second embodiment of a call reservation / connection service method according to the present invention. Only differences from the first embodiment will be described below.

In the second embodiment of the present invention, the service applicant is the caller, and the service operator is associated with a call reservation / connection service server (hereinafter referred to as a service server) as a mobile switching system.

FIG. 8 shows that the call reservation / connection service server 140 does not issue the call and virtual call transmission commands, but the mobile switching system 130 performs the call and virtual calls on the basis of the incoming and outgoing data from the service server 140. There is a difference in that it transmits, and others are the same. As shown in the flowchart of FIG. 9, when the calling party terminal 100 makes a call to the called party terminal 120, the mobile switching system 130 searches the database of the home location register 170 to locate the called party terminal 120. To find the data (S200, S210). If the location data of the called party terminal 120 is not registered, the mobile switching system 130 starts a call reservation / connection service (S220). The mobile switching system 130 causes the service server 140 to register incoming and outgoing data including the calling party terminal 100 and the called party terminal 120 in the database (S230). Matters relating to incoming and outgoing data are the same as those in the first embodiment. The mobile switching system 130 receives the incoming and outgoing data from the service server 140 and has a predetermined period (for example, 5 seconds) whether the location of the called party terminal 120 is registered in the database of the home location register 170. And retrieves the updated incoming / outgoing call data from the service server 140. When the called party terminal 120 is switched to the callable environment, the mobile switching system 130 transmits a virtual call toward the called party terminal 120 and a real call toward the caller terminal 100 (S270). It is determined whether the call connection button of the calling party terminal 100 or the called party terminal 120 is pressed within a predetermined time (for example, 30 seconds) (S275), and if not pressed, the number of call connection attempts of the incoming / outgoing data increases by one. The changed data is newly registered as incoming / outgoing data of the database of the service server 140 (S230). When the call connection button of the caller terminal or the callee terminal is pressed within the predetermined time, the call announcement button is first sent to the caller terminal 100 or the caller terminal 120 (S280), and the call connection of both sides 100 and 120 is made. When all the buttons are pressed, a call directed from the caller 100 to the caller 120 may be achieved by combining the real call of the caller 100 and the virtual call of the caller 120 (S290).

(Third Embodiment)

9 is a block diagram illustrating a third embodiment of a call reservation / connection service method according to the present invention, and FIG. 10 is a flowchart illustrating a third embodiment of a call reservation / connection service method according to the present invention. Hereinafter, only differences from the first and second embodiments will be described.

In the third embodiment of the present invention, the service applicant is a called party, and the service operator is a call reservation / connection service server (hereinafter referred to as a service server).

The difference from the first and second embodiments is that in the third embodiment, the called party is a service applicant, and the called party sends a service start command by himself or herself before turning off the terminal or entering a non-receiving area. The difference is that only the concept of real and virtual calls is redeemed, and the others are the same. As shown in the flowchart of FIG. 10, first, the service server 140 receives a service start command S300 from the called party terminal 120. Since starting the service immediately because there is a service start command unnecessarily wastes the system-wide resources, when the location data of the called party terminal 120 can no longer be found in the home location register 170, that is, the called party can The service is started when the terminal is turned off or enters an unreachable area (S310, S320). The service server 140 registers incoming and outgoing data in the database (S330), and instructs the mobile switching system 130 to transmit a real call to the called party (S340). The real call here serves to investigate whether the called party terminal 120 has been switched to the available state and serves to impose a call charge on the called party. Such a clear call command may be, for example, at 5 second intervals, but it should be taken into account that the shorter the period, the more the system operating resources are depleted. If the location of the called party's terminal 120 is input to the database of the home location register 170 and it is determined that the called party is in a callable state, the virtual call is directed toward the calling party terminal 100 while maintaining the real number headed to the called party's terminal 120. Send (S370). If the call connection button is not pressed within a predetermined time (for example, 30 seconds), the number of call connection attempts of the incoming / outgoing data is increased by one and the process returns to S330 again. When the call connection button is pressed within a predetermined time, the call guidement is sent to the caller 100 or the called party 120 that first press the call connection button (S380). Finally, when all the call connection buttons on both sides 100 and 120 are pressed, the call is achieved by connecting the called party's real call toward the calling party's virtual call (S390).

(Example 4)

11 is a flowchart illustrating a fourth embodiment of a call reservation / connection service method according to the present invention. Hereinafter, only differences from the first, second, and third embodiments will be described.

In the fourth embodiment of the present invention, the service applicant is a called party, and the service operator is a mobile communication system, which is combined with a call reservation / connection service server (hereinafter referred to as a service server).

In the fourth embodiment, the fact that the called party is a service applicant, and the called party makes a service start command by himself or herself before switching off the terminal or entering a non-receiving area, and switches only the concept of real and virtual calls is carried out. Same as the example, there is a difference in that the service operator is a mobile switching system 130, not the service server 140. As shown in the flowchart of FIG. 11, when a service start command is received from the called party terminal 120 through a voice mail service or the like (S400), the mobile switching system determines the position of the called party terminal 120 in the database of the home location register 170. When the data cannot be retrieved, the service is started (S410 and S420). The mobile switching system 130 registers incoming and outgoing data in the database of the service server 140 and receives the incoming and outgoing data from the service server 140 (S430 and S440). The mobile switching system 130 checks whether the location of the called party terminal 120 is input to the database of the home location register 170 at a period of, for example, 5 seconds (S450, S460), and the called party's terminal 120 location is inputted. If it is determined that the call is available, the mobile switching system 130 transmits the real call toward the called party terminal 120 and the virtual call toward the caller terminal 100 (S470). For example, if the call connection button of one of the calling party terminal 100 and the called party terminal 120 is not pressed within a predetermined time of 30 seconds, the process returns to S430. When the call connection button of either side is pressed within the predetermined time, the waiting guidement is sent to the first pressed caller 100 or the called party 120 (S480). The mobile switching system, when both of the call connection buttons on both sides 100 and 120 are pressed, combines the call from the called party 120 toward the caller 100 side virtual call, thereby achieving a call connection (S490).
