Abstract

PURPOSE:To reply a call with a portable telephone set by transferring a call to a wire telephone set when the portable telephone set is carried, that is, the user is absent. CONSTITUTION:When telephone sets having different telephone number such as a wire telephone set FTEL and a radio portable telephone set PTEL are used in common, the radio portable telephone set PTEL informs its state to a radio system controller RCE via fixed radio stations FRS 1-m according to a predetermined protocol to transfer wire telephone numbers xsi2011-2013 used in common by operating the radio portable telephone set PTEL or it is dismounted from a prescribed position. The radio system controller RCE receiving the notice transfers and sets the transfer wire telephone numbers xsi2011-2013 of the wire telephone set FTEL to the portable telephone set PTEL. Thus, a call reaching the wire telephone set FTEL while the user leaves his set position is transferred to the portable telephone set PTEL.

Description

Detailed Description of the Invention (1) Technical field to which the invention pertains The present invention provides a method for transmitting incoming calls to a wired phone when a mobile phone and a wired phone are not in use when the phone is used in combination with different telephone numbers. The present invention relates to a transfer setting method for smoothly transferring calls to a mobile phone and at the same time transferring incoming calls to a mobile phone to a wired phone while seated.

(2) Prior Art Currently, NTT's car phone is a communication system that allows users to make and receive calls while moving anywhere within a service area. NTT also provides mobile phone services using this network.

On the other hand, as cordless telephones have become more widespread, cordless telephone systems have been expanded, and a local mobile telephone system as shown in FIG. 1 has become possible.

This system consists of a radio system controller (RCE), a fixed radio station (FR3), and a mobile phone m (P location). Each element of this configuration will be briefly explained.

Here, the private branch exchange (PBχ) includes a wired system and a wireless system consisting of a wireless system controller RCE, a fixed wireless station FR3, and a mobile phone P, and performs exchange-related functions such as making and receiving calls.

It also has optional functions such as hold and transfer.

The mobile phone (P location) has a function of wirelessly accessing the radio system control device RCE via the fixed radio station FR3 and automatically registering its location. If it is necessary to register the location with another fixed wireless station due to the movement of the mobile phone P, it has a function of accessing the radio system control device RCE and changing the location registration. Call operations can be made from any location within the service area.

The fixed radio station (FR3) converts the downlink signal from the radio system control device RCE into a radio signal and transmits it to the mobile phone P, thereby allowing incoming calls and telephone conversations. On the other hand, by receiving and demodulating the upstream radio signal from the mobile phone P and transmitting it via wire to the radio system control device RCE, it is possible to perform an origination operation and a telephone conversation.

The radio system control equipment (RCE) connects the fixed wireless station FR3 that covers the radio wave zone of the location of the mobile phone P and the private branch exchange PBX extension that has a one-to-one correspondence with the mobile phone P. This is a device that connects when making and receiving calls to form a communication path.

Although mobile phone systems have become readily available in this way, mobile phones are originally something that people carry around with them, and are taken out and used when they leave their desks at the office. On the other hand, there is a wired telephone on the desk in the office, and this wired telephone is used when you are at your desk. At this time, it is preferable to use a wired telephone at a fixed location such as an office, and to leave the mobile telephone at rest to charge the battery. Furthermore, in order to eliminate unnecessary radio wave emission by using a mobile phone and to reduce the chances of these radio waves being intercepted as much as possible, it is common to use a wired phone.

However, although the above system is very useful because it allows the use of both wired telephones and wireless mobile telephones under one in-flight exchange, it is necessary to allocate different telephone numbers to each of them. In the mobile phone system using NTT's car phones, phone numbers are allocated based on different numbering plans from the viewpoint of billing, so it was impossible to make them the same as wired numbers.

For this reason, when you are in a fixed position, you can immediately answer a call whether it is received on a wired phone or a wireless mobile phone. At this time, the mobile phone's call bell does not ring and you cannot answer it because the phone number on the mobile phone is different from that of the wired phone. In this case, there is no point in carrying around a mobile phone.

Conversely, if a mobile phone is left in a fixed position and a call arrives at the mobile phone, it will increase the battery consumption of the mobile phone and emit unnecessary radio waves, causing wireless traffic. This increases the probability that other mobile phones are busy and makes it difficult to increase the number of mobile phones that can be accommodated.

Therefore, when you leave your seat or return to your seat from another location, you must manually dial the private branch exchange's forwarding function using your mobile phone or wired phone to set or reset the forwarding function. I am trying to do this, but
It's very tedious and I often forget about it, so I usually don't actually do it.

(3) Purpose of the Invention In order to eliminate these inconveniences, the present invention makes it possible to answer incoming calls on a wired phone by transferring them to the mobile phone when the mobile phone is taken out, that is, when the user is absent. Contrary to this, when the mobile phone is placed in a fixed position, incoming calls to the mobile phone can be set to be forwarded to the wired phone. This prevents battery consumption, eliminates the emission of unnecessary radio waves, contributes to a reduction in wireless traffic, reduces the probability that other mobile phones are busy, and increases the number of mobile phones that can be accommodated from other points of view. To provide a wireless telephone transfer setting method that is trouble-free and eliminates the need to forget to set or reset by automatically setting and resetting possible telephone transfers.

(4) Structure and operation of the invention The present invention will be explained in detail below with reference to the drawings.

Although the present invention relates to call forwarding, call forwarding itself is not a particularly new technology and can be accomplished in a variety of ways.

In the system shown in Figure 1, the private branch exchange PBX
The transfer function is used.

There are various methods for the transfer function of the private branch exchange PBX, but the following example will be used here.

For example, set the transfer set extension number to #12. The extension number for transfer reset is #16. When telephone X sets a "transfer set" to telephone Y, when telephone X calls the transfer set number #12, a chirp sound is heard. Next, send your phone number #XxxX. Then you will hear a tut tut tut sound, and at that time the forwarding number #YYY
Send Y. When this is connected, it makes a beeping sound and transfer is set. "Forwarding reset" is the same (call extension number #16 for forwarding reset from phone Transfer is reset.Here, transfer from phone X to own phone 4M
Although the transfer set/reset was performed using X, it goes without saying that the transfer set/reset of telephone X can be performed in the same manner from other telephones.

Now, as shown in FIG. 1, a case will be described in which a wired telephone with extension number #2010 and a mobile telephone with extension number #3020 are used together. first,
Let's talk about when you take your mobile phone out and use it.

Since a mobile phone is taken out, even if a wired phone in a fixed position receives a call, the person who is away from his/her seat cannot answer the call. Therefore, the wired telephone #2010 is set to be transferred to #3020, which is the extension number of the mobile telephone. By doing this, incoming calls to the wired telephone when the user is not at the regular location are transferred to the mobile phone, and the mobile phone #3020 can respond to the incoming calls to the wired telephone #2010. On the other hand, when the mobile phone is returned to its original position, there is no need to take the trouble to have the incoming call received on the wired phone arrive at the mobile phone, so the set transfer is reset. This brings us back to the beginning.

Next, looking at the mobile phone, there is no need to receive a call to the mobile phone when it returns to its normal position, so change the mobile phone number #3020 to #201, the wired phone number.
Transfer it to 0. Thus, in the fixed location, all incoming calls to the mobile phone are forwarded to the wireline phone. On the other hand, when you take your mobile phone out with you, you don't want it to be forwarded to your wired phone, so by resetting the forwarding to your mobile phone,
All incoming calls to a mobile phone will arrive at that mobile phone without reaching the wired phone.

In this way, in a certain fixed position, it becomes necessary to set/reset the wired/mobile phone at the same time when returning to one's seat with the mobile phone and when the mobile phone is taken out. An example of a configuration for realizing this is shown in the block diagram of FIG. FIG. 2 is a configuration diagram of a mobile phone for setting transfer according to the present invention. Figure 2 shows the control unit PC of the mobile phone.
The input port of U receives a signal from the charging terminal in order to sense that the mobile phone is placed in a predetermined position (in this case, on the charging stand). FIG. 2 shows a practical mobile phone in actual use. That is, when the user returns to the home after a trip, there is no need to turn on the mobile phone, but rather, the user has to charge the exhausted battery. Therefore, it is practical to detect when the device is placed on a charging stand.

Sensing that the phone is in place can be done by sensing the charging voltage, ripple during charging, sensing the charging current, or by installing a mechanical or optical switch on the phone. This can be done in various ways, such as by providing a magnetic field or by using magnetism.

It is necessary to set the mobile phone's own phone number and forwarding destination number in advance. FIG. 4 shows how the forwarding destination telephone number is preset on the mobile phone.

FIG. 3 shows the operation flow of the control unit CPU of the mobile phone. In FIG. 3, the control unit CPU constantly monitors whether there is any change in the boat input. If there is a change in boat input, proceed to the next step. When the portable filling machine is placed on the charging stand, the voltage is detected in the CPU manual boat, and the control unit CPU
uses this voltage to determine that the mobile phone has been placed in a predetermined position. The control unit CPU resets the transfer of the wired phone that was set to transfer from #2010 of the line phone to #3020 of the mobile phone, and then transfers the number of the mobile phone #2010 to #3020 of the mobile phone.
3020 to wired number #2010, a wireless line is set up for fixed wireless station FR3 and a signal is sent. The fixed radio station FR3 receives this and sends a transfer reset request, a transfer request, and a transfer destination number to the radio system control device RCE. Next, the radio system control device RCE sends these processed signals to the private branch exchange PBX, and the transfer reset/set is completed. A termination signal from the private branch exchange PBX is transmitted to the radio system control device RCE, the fixed radio station FR3, and the mobile phone PTEL, respectively, and the series of operations ends.

In the opposite case, the control unit C of the mobile phone P
When the voltage is no longer detected at the port input of the PU, the control unit CPU detects a change in voltage and determines that the mobile phone P TEL has been removed from the predetermined position. #30
The state where #3020 of the mobile phone P is transferred to the wired phone #2010 via route 20 is reset, and then the wired phone number #2010 is transferred to the number #3020 of the mobile phone P In order to set this, a wireless line is set up for fixed wireless station FR3 and a signal is sent out. The fixed radio station FR3 receives this and sends a transfer request, a transfer destination number, and a transfer reset request to the radio system control device RCE. Next, the radio system control device RCE sends these processed signals to the private branch exchange and completes the transfer set/reset. The termination signal from the private branch exchange @PBX is sent to the wireless system control device RCE, fixed wireless station FR3, and mobile phone P.
The series of operations is completed by transmitting data to each location.

As explained above, the present invention determines whether the mobile phone P is "placed" or "removed" and automatically sets and resets the transfer.

By combining it with a charger in this way, charging and transfer operations, which are originally required by the portable charger Pr, can be performed at the same time, which is convenient because one will not be forgotten.

As another embodiment, it goes without saying that the present invention can be implemented in the same way in a case where the radio system controller RCE has an exchange function and both a wired telephone and a wireless telephone are connected to the radio system controller RCE. .

In the example above, we only explained when the phone is placed on the charger, but if you attach a specific key to the mobile phone, for example, r##
This can also be achieved by pressing #J three times to perform this action.

(5) As described in detail, the present invention not only enables incoming calls received on a wired phone to be forwarded to a mobile phone when the user is not at a fixed location, but also enables the setting and resetting of forwarding at the same time. This prevents calls from being received on the mobile phone when the user is seated in a fixed position, which has the extremely large effect of preventing the battery of the mobile phone from draining and reducing wireless traffic. is producing. Also, by combining it with a charger, it is very convenient to avoid forgetting either the charging or the transfer set.

It should be noted that this cellar 1-reset is convenient in use because it only needs to be placed on the charging stand and no special operation is required.

Other advantages of the present invention are that there is no need to equip special hardware for transfer setting;
This has the advantage of being able to significantly reduce costs since it can be handled with just one person.
