Abstract

PURPOSE: A call forwarding method is provided to make a subscriber register a specific time interval during which he is supposed to be at a specific place and an associated destination number so that a call transmitted to the subscriber can be transferred for the registered time. CONSTITUTION: Subscriber A registers subscriber D's destination number for calls during an appointed time and subscriber C's destination number for calls except the appointed time. If subscriber A is called, a CFWT(Call ForWarding Timed) block judges whether the present time is within the appointed time. In the case that the present time is within the appointed time, the CFWT calls the subscriber D's destination number and forms a speech path between subscriber A and subscriber D. If the present time is not within the appointed time and an unconditional CFW mode is set, the CFWT calls the subscriber C's destination number and forms a speech path between subscriber A and subscriber C. If subscriber A responds to the call in the case that the present time is not within the appointed time and a conditional CFW mode is set, the CFWT forms a speech path between subscriber A and subscriber B. If the line is busy or there is no answer for 15 seconds in the case that the present time is not within the appointed time and the conditional CFW mode is set, the CFWT forms a speech path between subscriber B and subscriber C.

Description

Call forwarding method {CALL FORWARDING METHOD}

The present invention relates to a call forwarding method, and more particularly, to a call forwarding method in which a subscriber who moves to a plurality of places designates a specific time, and when a call is registered at the designated time.

In general, call forwarding (CFW) is a call forwarding in the absence of the user to the other forwarding number registered by the condition.

The call forwarding methods include unconditional call forwarding and conditional call forwarding. The unconditional call forwarding is unconditionally switched to the registered number when the other party calls, regardless of whether the call is received or not received. In the case of not receiving it within the set time or in the case of changing to a number registered in advance, such a prior art will be described with reference to the accompanying drawings.

1 is a flowchart illustrating an exemplary embodiment of a conventional call forwarding method. When a call forwarding registration 'subscriber A' is called as shown in FIG. 1, a first step of determining a current forwarding mode; A second step of forming a call path between the subscriber B and the subscriber C by switching the incoming call to a predetermined number of subscribers C in the unconditional switching mode as a result of the determination of the first step; A third step of determining a response state in the conditional switching mode as a result of the determination in the first step; As a result of the determination in the third step, if the subscriber A responds to the idle state, a call path is formed between the subscriber A and the subscriber B, and if the caller is idle or idle for 15 seconds, the predetermined subscriber C The fourth step of forming a call path between the subscriber B and subscriber C by switching the incoming call to the number of ',' will be described.

First, call forwarding registered subscriber should register unconditional call forwarding conditional or conditional call forwarding function in the phone. If you want to transfer (unconditional call forwarding registration), if you pick up the phone and hear the dial tone normally, press '* → 88 → TDN (unspecified number) → *' to register the call forwarding service. A tone is sent to the subscriber A's handset to signal completion of registration.

In order to confirm completion of the unconditional call forwarding registration, the subscriber A can be confirmed by holding the handset and pressing '* 84TDN *', and entering '# 88 *' to cancel the unconditional call forwarding registration function unconditionally. Cancel call forwarding registration.

At this time, the conditional call forward registration method is also the same as the unconditional call forward registration method described above, except that the corresponding code is different.

FIG. 2 is a block diagram of a device for performing an incoming call service. The ASC block controls a voice subscriber incoming process and outputs a call forwarding request accordingly. When a call forwarding request is input from the ASC block, FIG. Register the divert and perform the origination processing of the registered call.

At this time, in the CFW block, CFWU block is performed if unconditional call forwarding, CFWC block is performed if the conditional call forwarding.

In addition, the NTR block translates the special service code registered by the subscriber, the incoming call conversion type, and the called phone number, and transmits the related information to the ASC block and the CFW block to perform call processing.

Here, if 'subscriber A', which has registered call forwarding, sets call forwarding to 'subscriber C' and then, when absent, 'subscriber B' calls for 'subscriber A', the current forwarding mode is determined. The call forwarding is performed accordingly, i.e., when the call forwarding mode is set to unconditional call forwarding mode, the call forwarding is performed between the subscriber B and the subscriber C by transferring the call to the call forwarding number preset by the subscriber A. Form.

On the other hand, when the conditional call forwarding mode is set, if the subscriber A responds, a call path is formed between the subscriber A and the subscriber B, and if the call is idle or idle for 15 seconds, the predetermined number ' The call is transferred to subscriber C and a call path is formed between subscriber B and subscriber C.

However, in the prior art as described above, since the incoming call transfer service exists only conditional call forwarding and unconditional incoming call phone service, there is a problem that the subscriber does not receive the incoming call service when the subscriber moves from the designated number to another place. there was.

Therefore, the present invention invented in view of the above problems gives a subscriber a mobility and time concept to the subscriber using the call forwarding service to register the time and the destination number expected to move to a specific place to call the incoming call to the subscriber Its purpose is to provide a call forwarding method that enables the forwarding for a specific time.

1 is a flowchart illustrating a conventional call forwarding method.

Figure 2 is a schematic diagram showing the configuration of a device to which the conventional call forwarding method is applied.

Figure 3 is a schematic diagram showing the configuration of the apparatus applied to the present invention transfer method.

Figure 4 is a flow chart of the operation of the present invention.

The present invention for achieving the above object comprises a first step of registering, by the subscriber, a first incoming telephone number for a call within a designated time and a second incoming telephone number for a call other than a designated time; A second step of determining, when a call forwarding registered subscriber is called, whether a current time is included in the designated time; A third step of forming a call path between the caller and the first incoming phone number by calling the first called number if the current time is included in the designated time as a result of the determination of the second step; A fourth step of forming a call path between the caller and the second called number if the current time is not included within the designated time and is unconditionally called forwarding registration as a result of the determination of the second step; A fifth step of forming a call path between the caller and the subscriber when the subscriber responds when the current time is not included in the designated time and the conditional call forwarding registration is determined as the second step; A sixth step of forming a call path between the caller and the second forwarding number if the current time is not included within the designated time and is a conditional call forwarding registration, if the subscriber is busy or does not answer for several seconds. It is characterized by performing as.

Hereinafter, with reference to the accompanying drawings, the operation and effect of the call forwarding method of the present invention will be described in detail.

Figure 3 is a schematic diagram showing the configuration of the apparatus to which the present invention transfer method is applied, as shown in the general configuration is the same as the conventional Figure 2, but switching to the original originating party in charge of outgoing processing when switching timed calls A call forwarding timed (CFWT) block is further included to allow call processing between the called party.

Fig. 4 is a flowchart showing the configuration of the present invention's call forwarding method. As shown in FIG. 4, the subscriber A's incoming telephone number and time other than the designated time are designated by the subscriber A. A first step of registering an incoming phone number of subscriber 'C' for the call; A second step of determining whether a call forwarding registration 'subscriber A' is called if the current time is within the designated time; A third step of forming a call path between 'subscriber A' and 'subscriber D' by calling the subscriber D called number if the current time is included in the designated time as a result of the determination of the second step; As a result of the determination of the second step, if the current time is not included in the designated time and the call forwarding registration is unconditionally called, the calling phone number of the subscriber C is called to form a call path between the subscriber A and the subscriber C. Performing a fourth step; A fifth step of forming a call path between the subscriber B and the subscriber A when the subscriber A responds when the current time is not included within the designated time and conditional call transfer registration is determined as the result of the second step; Wow; As a result of the determination of the second step, if the present time is not included in the designated time and is a conditional call forwarding registration, if the subscriber A is busy or does not answer for 15 seconds, the caller between subscribers B and subscriber C is called. The sixth step of forming the furnace is described, and this operation of the present invention will be described.

First, in FIG. 3, subscriber A registers an unconditional call forwarding service unconditionally with a called party number of subscriber C and registers a designated time forwarding service until 10: 00 ~ 12: 00 with a called party number of subscriber D. After completion, when the subscriber A is absent, if the subscriber B calls the subscriber A, it is determined whether the calling time is included in the designated time.

As a result of the determination, if the call time is included within the designated time, the called number of the subscriber D is called to form a call path between the subscriber B and the subscriber A moving toward the subscriber D.

On the other hand, if the call time is not included within the designated time, and the unconditional call forwarding is registered, the 'subscriber B' and 'subscriber C' to move to the destination number of 'subscriber B' and 'subscriber C' A currency path is formed between A '.

If the call time is not included in the designated time and conditional call forwarding is registered, when the subscriber A responds, a call path is formed with the subscriber B, and the telephone of the subscriber A is busy. If no response is made for 15 seconds, a call path is formed between subscriber B and subscriber C.

At this time, when the designated time forwarding service code is described, first, the registration time code is set by pressing '* → 85 → called phone number → [month / day] → [start time / end time] → *'.

Then, when canceling, the code is set by pressing '* → 89 → *', and when it is confirmed, the code is set by pressing '86 → called phone number → [start time / end time] '.

Here, the designation of [month / day] can be omitted, and if omitted, the month / day is automatically set.

As described in detail above, the present invention provides a mobility and time concept to subscribers using an incoming call transfer service to convert a call received to a subscriber during a designated time by registering a time and an incoming number expected to move to a specific place. It can be effective.
