When the employee 10 is working outside the company, such as outing or travel, there is a necessity of communication for the company's work, but if the communication cost is a problem, the company through the public communication network 20 of the local area that is out of work Is connected to a private exchange 30 operating at.

For example, when the employee 10 is connected to the private exchange 30, a specific password and a telephone number through which the employee 10 can communicate with each other within a predetermined time or by automatic guidance, and input the password When the recognition of the back is confirmed, the connected telephone is disconnected or waited for a while in the state of being first connected to the private exchange 30, and then communicated by connecting to a co-worker 40 working there through the corresponding dialing.

When the employee 10 enters the corresponding password and telephone number in the private exchange 30 and hangs up the connected CALL, a call for communication to the corresponding phone number input by the employee 10 later ( CALL) is automatically connected, and the employee 10 can select and call and communicate any unspecified recipients 50 through the private exchange 30, the communication fee is added to the private exchange 30 ) To bear it.

Therefore, the employee 10 has the advantage that can freely communicate necessary for work without worrying about the communication costs in the outlying area.

However, the callback service scheme according to the related art has a problem in that the private exchange 30 must be provided or installed or operated, or in the case of the public communication network 20, the callback service as described above must be provided. have.

In addition, there is a problem in that the callback service is not provided when the mobile communication system such as the wireless subscriber network (WLL) is not provided or the private exchange 30 is not provided. have.

An object of the present invention is to provide a method for receiving a callback service from the outside by using a terminal of a wireless subscriber network (WLL) to which a caller ID (CID) verification function is added.

In order to achieve the above object, the present invention provides a caller authentication number that allows a terminal subscribed to an exchange of a WLL system to extract a caller number included in a received signal and receive the callback service pre-stored in the extracted number. Caller verification process to check whether it is included in the list, and if the caller number currently called during the caller identification process is confirmed that the callback service is allowed, the WLL terminal terminates the hand signal and calls back to the caller number to callback A callback process for processing a function, a conference call request confirmation process for checking whether there is a conference call request from a corresponding caller called back during the callback process, and a terminal when the caller does not request a conference call during the conference call request confirmation process A communication process that generates an incoming ring at the terminal and proceeds to the communication mode to complete the communication. It provides a callback service management method of a wireless subscriber network consisting of.

In addition, referring to the accompanying Figure 4, the method for operating a wireless subscriber network callback service according to the present invention, in a callback service method using a wireless subscriber network (WLL) system,

The terminal 80 subscribed to the switchboard 70 of the wireless subscriber network system continuously receives a reception process (S100) for continuously checking whether an incoming call signal generated by the caller 60 is input.

When the terminal 80 confirms the call from the caller 60 in the receiving process (S100), the caller's call number or phone number (CID: CALLER IDENTIFICATION NUMBER) is confirmed and a callback service is permitted. In order to confirm caller identification, the terminal 80 receives a caller number (CID) authorized from the exchanger 70 and confirms it by a first step (S110); The terminal 80 reads a list of caller authentication numbers LIST that can be provided with a callback service from a corresponding memory writer (S120); A caller identification process comprising a third step (S130) of checking whether the authentication number list read in the second step (S120) includes the caller number (CID) received by the first step (S110);

When the caller (CALLBACK) service is confirmed as the caller allowed in the caller identification process, the terminal 80 blocks the call received from the caller 60 and calls the caller again by the terminal. A fourth step (S140) of storing the calling party number (CID) blocked by the terminal 80 in a corresponding memory and blocking the caller's call (CALL); Calling is blocked by the fourth step S140, and the terminal 80 accesses the call again using the caller ID stored in the corresponding place. A fifth step (S150); A callback process comprising a sixth step (S160) of checking whether the caller 60, which is connected again by ORIGINATION in the fifth step (S150), is hooked off for communication;

When it is confirmed that the caller 60 requests the CONFERENCE CALL in the conference confirmation process (S170), the terminal 80 transmits the requested conference call progress signal and the telephone number of the conference call counterpart to the wireless subscriber network ( A conference connection process (S180) for transmitting to the exchange 70 of the WLL system to be connected to the counterpart 90;

A connection confirmation process (S190) for checking whether a conference call counterpart (90) connected in the conference connection process (S180) is off-hook for communication and proceeding to the communication process;

If the caller does not request the CONFERENCE CALL (60) in the meeting confirmation process (S170), a call ring is generated in the terminal 80 and the communication process is terminated after the communication proceeds to the communication mode (S200). It is composed of

In addition, when the calling party number (CID) received in the caller identification process (S130) is not included in the authentication number list (LIST) recorded in the terminal 80 proceeds to the communication process (S200).

Hereinafter, according to the present invention having the configuration described above, a callback (CALLBACK) service apparatus of the wireless subscriber network and its operation method will be described in detail with reference to FIGS.

The present invention is to use a cellular mobile communication system, using a terminal 80 that is subscribed to the switch 70 constituting a wireless subscriber network (WLL) system to receive a wireless subscriber network service, the communication cost from the outside It is to provide a callback service that can communicate such as a telephone without using.

The callback service of the present invention using the wireless subscriber network (WLL) as described above is largely classified into two types, one of which includes an external callback service beneficiary and a terminal 80 subscribed to the wireless subscriber network (WLL). It is to communicate without burdening communication cost.

The other is that the external callback service beneficiary conducts a CONFERENCE CALL simultaneously with the other party 90 as another external accessor, including the terminal 80 subscribed to the wireless subscriber network (WLL).

The above-mentioned CONFERENCE CALL allows three or more persons to communicate at the same time, and it is a method in which the remaining accessors can continue to communicate even if any one of the conference callers ends the communication.

The exchanger 70 constituting the callback service device of the wireless subscriber network system having the above functions is operated by adding a caller ID (CID) checking function, so that the caller connected by wired or wireless or modem (MODEM) or the like ( When 60 is connected and calls the WLL terminal 80, the called terminal 80 is notified of information on the caller 60's unique telephone number and the like, and is equipped with a conference call function and has three or more characters. It provides a conference call service for simultaneous calls.

The terminal 80 analyzes caller ID (CID) identification information from the exchange 70 to identify and store the caller's unique telephone number, and provides a callback service. An external caller (60) phone number that can be provided with a callback service of, i.e., a record of the authenticated unique telephone number as a list, and the caller number authorized from the exchange 70 is recorded in the authenticated number list. Make sure it is included.

The counterpart 90 makes a conference call with the caller 60 and the terminal 80 by a call connection (ORIGINATION) applied through the switch 70 by the call of the terminal 80.

Referring to FIG. 2, the wireless subscriber network callback service apparatus according to an example will be described. When the caller 60 connects to an exchange 70 of the wireless subscriber network and calls the terminal 80, The exchange 70 notifies the terminal 80 of an alert signal or call ring signal informing the called party with a corresponding information message such as a caller number (CID).

As described above, the terminal 80 called from the caller 60 stores the caller ID CID in the corresponding storage device, and then blocks the call by the caller 60 and stores the caller 60 in the storage device or memory. By reading the calling party number (CID) and outputting the corresponding call signal (ORIGINATION MESSAGE) to the exchange 70 provides a callback (CALLBACK) service for calling the caller (60).

In such a case, the caller 60 communicates with the caller 60 by the callback service so that the caller 60 does not bear the communication fee.

3, the caller 60 communicates with an external party 90 who is not subscribed to the wireless subscriber network, or a conference call with the terminal 80 and the other party 90. This is the configuration of the callback service device to be performed at the same time.

Since the callback service to which the caller 60 and the terminal 80 of FIG. 3 are connected is the same as the description of FIG. 2, a detailed description thereof will be omitted and only the necessary parts will be described. Call to explain the conference or conference communication process.

When the caller 60 provided with the callback service (①, ②, ③) by the terminal 80 wishes to communicate with the external counterpart 90, the caller conference or conferences the unique number of the counterpart 90. The terminal transmits the signal to the terminal 80 together with a signal to request communication (④).

The terminal 80 receiving the conference call request signal of the caller 60 and the unique telephone number of the counterpart 90 (④) is a request signal for a three-way simultaneous communication or conference call, for example, a hook flash signal. And the like to the wireless subscriber network switch 70 (⑤).

The wireless subscriber network switch 70 receiving the above signal calls or connects the other party 90 to connect a call, and the caller 60 and the terminal 80 use the conference call function. , The other party (90) to have a conference call at the same time (⑥).

In this case, the caller 60 applies the corresponding signal to the terminal 80 so as not to communicate with the terminal 80 or when the terminal 80 terminates the communication during the conference call. And communication between the other party 90.

Referring to FIG. 4, the method for operating the wireless subscriber network callback service according to the present invention will be described in detail. The terminal 80 calls or receives the corresponding signal from the caller 60 through the switch 70. It is continuously checked whether the bell signal is applied (S100).

When the caller 60 confirms that the caller 60 is calling according to the above confirmation, the terminal 80 keeps the current hook on state, and the caller ID (CID) confirmation service from the exchange 70. After receiving and confirming the unique number of the sender 60 authorized by the (S110) is stored in the memory or storage device.

The terminal 80 reads the caller 60 number list LIST authenticated to receive the callback service from the corresponding memory (S120), and unique to the caller 60 received by the caller ID (CID) verification service. Check whether the number is included (S130).

If the corresponding unique number of the caller 60 is not included in the authentication number list by the confirmation (S130), the user performs a hook off by operating an incoming ring of the terminal 80 itself. By doing so, communication, that is, normal communication and ends (S200).

When the corresponding unique number of the caller 60 is included in the authentication number list in the third step (S130) of the caller identification process, the terminal 80 is the caller in the state that the current hook on (HOOK ON) is maintained The number CID is stored in a separate memory, and the call CALL is blocked from the caller 60 (S140).

By the fourth step (S140) of the callback process, the terminal 80, which blocks the call (CALL) with the caller 60 is a unique number of the caller 60 stored in a separate corresponding memory in the step (S140) Alternatively, by using the unique telephone number, the call request signal is applied to the switchboard 70, and the switchboard 70 calls the caller 60 again, and a callback service is made (S150).

When the caller 60 called or connected by the callback service (ORIGINATION) by the fifth step (S150) of the callback process hooks off for communication (S160), the terminal 170 is connected to the caller 60. Check whether a 3-way call or a conference call is requested (S170).

If the caller 60 does not request a 3-way call or a conference call in the final confirmation process (S170), the process proceeds to the communication process (S200) and the terminal 80 By generating an incoming ring or a ringing bell to allow the user to hook off, the caller 60 and the terminal 80 communicate with each other by the callback service, which is the same process as described in FIG.

In the meeting confirmation process (S170), when the caller 60 requests a three-way call or a conference call, that is, the conference call request signal and the conference sent by the caller 60 When it is confirmed that the telephone number of the other party 90 to be called is input, the terminal 80 requests a conference call to the wireless subscriber network switch 70, for example, a hook flash signal. At the same time outputting the unique number or the telephone number of the other party (90) (S180).

The exchange 70 analyzes and processes the authorized three-party call or conference call information from the terminal 80 as described above, allocates a conference call resource (RESOURCE) for the conference call, and calls the counterpart 90 at the same time. If the counterpart 90 wishing to make a conference call is hooked off for communication (HOOK OFF) (S190), the process proceeds to the communication process (S200).

As described above, the caller 60, the terminal 80, and the counterpart 90 make a three-way or conference call by a callback service.

At this time, the caller 60 is called by the callback service when the call (CALL) is blocked while outputting a separate control signal to the terminal 80 to prevent an incoming ring or ringing ring from occurring on the terminal 80. Communication is made only with the 90, and communication between the caller 60 and the counterpart 90 continues even when the terminal 80 blocks the call during the conference call.

Accordingly, the configuration of the present invention as described above can provide a callback service to a limited user authenticated using a wireless subscriber network (WLL) terminal.

The present invention of the above configuration has the effect of providing a callback service to a limited authenticator using a wireless subscriber network, in particular, using a wireless subscriber network terminal.

In addition, since the additional service of the callback service is added to the wireless subscriber network, there is an industrial use effect of improving the reliability of the user and extending the application range of the communication product.
