Abstract

PURPOSE: The method is provided to reduce the access time of the waiting call by using one touch function of a CT-2(Cordless Telephone Generation 2). CONSTITUTION: A control part detects a special number from a received number(415). The detection of the special number means that a standby access function is performed through one touch function of a CT-2(Cordless Telephone Generation 2). And, one touch function is a function for accessing a waiting call with once key input. When the special number is not detected, the control part receives a post box service number(421). After this, the control part detects the special number(423), and compares the special number to a stored special number(425). When the special number is the same as the stored special number, the control part detects a present received number(427), and checks whether the present received number is a waiting call access number or not(429). When the present received number is the waiting call access number, the control part accesses the waiting call(431).

Description

Shortening call waiting time using one-touch function of calling-only phone

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a call waiting method of a CT-2 terminal (Citi-2 telephone; call-only phone), and more particularly to a call waiting method using a one-touch function of a terminal.

In general, the CT-2 switch may provide only subscribers with outgoing calls, but may also provide service for hand signals using a VMS connected to a wireless call network.

Hereinafter, the air call connection according to the prior art will be described in detail with reference to FIG. 1.

Hereinafter, the control unit is a CPU (central processing unit) that manages the overall operation of the VMS connected to the wireless call network.

First, the control unit 10 detects a call connection to a voice mailing system (VMS) in step 111, and receives a mailbox number for the call in step 113. In step 115, the control unit 10 sends a guide message, and in step 117, the mailbox service number checks the reception (for example, number 3).

Here, the guide message is a general message transmitted when a pager number is dialed and is a message for guiding a call or voice recording. The mailbox number is one of subscriber information registered corresponding to the subscriber number of the CT-2 terminal, that is, the mailbox number means a VMS number for the call to be implemented in the corresponding VMS.

The controller 10 detects a password based on the number received in step 119, and checks whether the received number is the same as the password in step 121. In this case, if the received number is the same as the password, the process proceeds to step 123. If the password is different from the password, the controller returns to step 119 to continuously detect the received number.

Recognizing that the received number is a password, the controller proceeds to step 123 and sends a guide message to the CT-2 terminal. The guide message is a guide message of various services. Of course, the message also includes a key guide regarding the waiting call connection.

The user selects a required service by the guide message, and the controller 10 detects a number received in step 125 and checks whether the received number is a waiting call access number in step 127.

In this case, if the received number is a waiting call access number, the controller proceeds to step 129. If the call number is not the waiting call access number, the controller proceeds to step 131 to perform a service corresponding to the received number.

On the other hand, recognizing that the received number is a waiting call access number, and proceeding to step 129, the controller connects to a call waiting for a CT-2 subscriber connected to the VMS and relates to a waiting call connection of a CT-2 exchange. Quit this program.

That is, when any public switched telerhone network (PSTN) subscriber wants to talk to a CT-2 subscriber, the caller first calls the CT-2 subscriber and waits for a call connection in a call waiting state. That is, the caller is waiting for a call connection while holding the telephone, and the CT-2 subscriber recognizes that any subscriber wants to talk to herself through the beep and display window attached to his terminal.

Accordingly, the CT-2 subscriber makes a phone call with the waiting caller by dialing his / her subscriber number and inputting a password and a waiting call connection number according to the voice guidance provided from the VMS.

At this time, the CT-2 subscriber must press a 6-7 digit number for the call connection, such as a password for the mailbox service and his password and a waiting call connection number, for a call to the waiting call. A factor has occurred.

This not only provides inconvenience to the user, but also increases the holding time of the CT-2 switch and the VMS system, thereby improving the traffic of the system.

In addition, CT-2 subscribers need to know that any caller is requesting a telephone call with them, and call the user's mailbox, enter the password and call waiting number, and call each other. This is contrary to the taste of modern people's currency.

In particular, the wireless call network requires a shortening of the time to call a beep and the time it takes the CT-2 subscriber to connect to a waiting call after making a call to the VMS. It is not easy to reduce the delay it takes to inform the caller of the call waiting. Therefore, it is absolutely necessary to shorten the time required for CT-2 subscribers to connect to the waiting call by calling VMS.

In addition, it is possible to shorten the input time of 7 numbers such as password and waiting call connection number that need to be input to call connection to VMS, but it does not affect the call connection time reduction absolutely. It is not inconvenient to enter your password and waiting number connection number one by one.

It is therefore an object of the present invention to provide a method for shortening the standby call connection time of a CT-2 switch.

Another object of the present invention is to provide a method for shortening the wait call connection time through the one-touch function of the CT-2 terminal.

A method for shortening a call waiting time using a one-touch function of an outgoing dedicated telephone for achieving the above objects includes a subscriber entering a voicemail device connected to a wireless call network and calling a Citi-2 subscriber. Performing a call waiting with a subscriber, transmitting a Citi-2 subscriber's own subscriber number and a special number displayed on a display window of a terminal by using a calling key, and receiving the voice by the calling process. Performing a call connection to a mailbox device, checking the reception of a mailbox number and a special number after detecting the call connection, and detecting the reception of the mailbox number and a special number. Characterized in that the process of performing a call connection between the subscriber and the Citi-2 subscriber.

Figure 2 is a block diagram of a CT-2 switch in accordance with the present invention.

Figure 3 is a network diagram and a call (CALL) flow chart for the incoming service of the CT-2 switch in accordance with the present invention.

4 is a flowchart illustrating an operation of waiting call connection using a one-touch function of a CT-2 terminal according to an embodiment of the present invention.

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

Hereinafter, a simple definition of the words to be continued in the present invention are as follows.

First, the mailbox number is one of subscriber information registered corresponding to the CT-2 subscriber number, and the mailbox number is a VMS number for placing a call entered into the CT-2 exchange into the corresponding VMS.

The special number is a special character that is displayed along with the subscriber number on the LCD of the CT-2 terminal when the call waiting function is performed by the caller's beeping call. By sending the subscriber number and the special number by the SEND KEY, it is possible to immediately connect with the waiting call.

Hereinafter, a block configuration of the CT-2 switch according to the present invention will be described in detail with reference to FIG. 2.

The PSTN matching unit 211 performs various relay line connection functions of the public telecommunication network, incoming calls, and outgoing calls.

The CT-2 matching unit 212 performs various call processing functions of the CT-2 and converts the CT-2 subscriber number into a pager number of the called party. Main functions include relay call function, VMS call processing function, national data processing function, number translation function, VMS incoming call processing function and CT-2 subscriber data management function.

The paging exchange matching unit 213 connects to an existing paging exchange and performs paging origination function through No. 7 signaling or TNPP (T.P.P.) protocol. This is because using the TNPP protocol can save time.

The VMS matching unit 214 performs MEET-ME and various APPLICATION and maintenance functions by matching with the VMS. The VMS matching unit 214 performs a linked access procedure on the D-channel (LAPD). P. D) to match the incoming call.

The X.25 matching unit 215 transmits the CAMA (Centralized Automatic Message Account) charging data to the CT-2 network management device using the X.25 protocol.

The control unit 216 controls the system as a whole and performs maintenance, test and measurement, statistics and various input / output control, and exchange connection functions to distribute the system resources.

Hereinafter, a call flow process for providing an incoming service based on the above configuration will be described in detail with reference to FIG. 3.

In the first process, any subscriber (general subscriber, CBX, HHP, CT2) dials the CT-2 subscriber number and accesses the PSTN network 311. For example, suppose you dialed 016-460-1234.

The second process is a process of performing routing based on the dialed number in the PSTN network 311 and connecting to the CT-2 switch 312.

In the third process, the CT-2 switch 312 translates the received subscriber number to obtain subscriber information (VMS number; mailbox number).

The fourth process is a process in which the CT-2 exchange 312 calls the call to the VMS313 in which the subscriber information is mounted through a LAPD link. At this time, the subscriber listens to the announcement broadcast from the VMS313, and the subscriber selects the 'waiting function' based on the announcement and waits for a call without hanging up.

The fifth process is a process in which the CT-2 switch 312 performs OUT-DIALING to a pager number registered corresponding to the subscriber number.

A sixth process is a process in which a paging system (TDX-PS) 314 receives a PAGING message from the CT-2 exchange 312 using the TNPP protocol. In this case, the message is a subscriber number including the 016.

A seventh process is a process in which the paging system (TDX-PS) 314 transmits the paging message received from the CT-2 switch 312 through each base station (BS) 215 over the air.

The eighth process is a process in which the message transmitted over the airwaves is received by a pager attached to the corresponding CT-2 terminal 316. At this time, the subscriber number 016-460-1234 and the special number are displayed on the display window of the CT-2 terminal, and a ring tone is sent out to the speaker at the same time.

The ninth process is a process in which the CT-2 subscriber performs a call waiting function with a simple operation. For example, the subscriber number and the special number are displayed on the display window of the CT-2 terminal receiving the call data, and the subscriber performs the call waiting function by pressing the call key (SEND) of the terminal.

In step 10, the CT-2 base station 317 receives the digits dialed by the origination key input and re-dials the PSTN network 211.

Step 11 is a process in which the PSTN network 311 routes the call corresponding to the dialing to the CT-2 switch 212.

In step 12, the CT-2 switch 312 translates the received subscriber number to obtain subscriber information (VMS number; mailbox number).

In step 13, the CT-2 switch 312 calls the corresponding call to a VMS213 mounted with a subscriber through a LAPD link.

Finally, step 14 is a process in which the VMS313 analyzes the special number received together with the mailbox number and immediately connects the waiting call with the CT-2 subscriber to make a real time call. The above process is a process in which the MEET-ME (meat-me) is performed in the VMS213.

Hereinafter, an operation process according to the present invention will be described in detail with reference to FIG. 4.

The control unit is a CPU (central processing unit) that controls the overall operation of the VMS313.

First, the control unit detects any call connection to the VMS313 in step 411, and receives the mailbox number for the call in step 413.

The controller detects a special number by detecting a number received in step 415. In this case, when the special number is detected, the controller proceeds to step 431. If the special number is not detected, the controller proceeds to step 419.

Herein, the detection of the special number means performing the call waiting function through the one-touch function of the CT-2 terminal according to the present invention. That is, the one-touch function refers to a function of directly accessing a waiting call by inputting only one calling key (SEND key) of his / her subscriber number and special number displayed on the terminal as the CT-2 subscriber receives a call.

Since the special number is not detected, the controller proceeds to step 419 and transmits a guide message to the CT-2 terminal. In step 421, the controller receives a mailbox service number (for example, number 3). In this case, the guide message is a guide message for requesting input of a number and voice recording as a general message transmitted when a call number is dialed.

The controller detects a password based on the number received in step 423, and checks whether the received number is the same as a password preset by the subscriber in step 425. In this case, the received number is the same as the password, and the controller proceeds to step 427, and the controller differs from the password, and the controller proceeds to step 423 to continuously detect the received number.

After checking that the received number is a password, the controller proceeds to step 427 and detects the currently received number. In step 429, the controller checks whether the received number is a waiting call access number. In this case, if the received number is a waiting call access number, the controller proceeds to step 431. If the call number is not the waiting call access number, the controller proceeds to step 433 and performs a service corresponding to the received number.

On the other hand, in step 417, the special number is detected, or in step 429, the received number is a call waiting number, and the control proceeds to step 431. The control unit is currently waiting for a telephone call with the CT-2 subscriber. Performs call connection with subscriber and terminates this program about waiting call connection of CT-2 exchange.

As described above, the present invention can shorten the time taken for the CT-2 subscriber to connect with the waiting call, thereby shortening the holding time of the CT-2 switch and the VMS. As a result, call traffic can be reduced, as well as faster call calls can be connected to the caller, increasing service competitiveness.
