DE102004030941A1 - Method of call diversion used with e.g. private automatic branch exchange, first detects presence or absence of user by means of sensor - Google Patents

Abstract

Automatic call diversion from a first terminal unit to a second, is achieved by sensor detection of local presence or absence of user, before automatic and immediate, speech and/or data connection diversion. Diversion alternatively follows a number of ringing signals. The sensor unit used, is connected to a PC. Automatic, non-contacting detection of arrival or departure of a user into or from his local zone, is detected by a sensor system. An independent claim is included for the corresponding sensor unit.

Description

The The invention relates to a method for call diversion in a telephone system according to the preamble of claim 1.

Known is a manually activated call forwarding in a telephone system. Incoming telephone calls can for example, immediately from a landline terminal to a mobile terminal (cell phone) be redirected. Is the landline terminal on one Workplace, a person can use one on a phone number the mobile terminal Call forwarding can be achieved at any time or at any place, for example, on business trips. However, this feature has the disadvantage that activation of the call forwarding can be forgotten, whereby the corresponding subscriber is not available by telephone. Also can forget to disable a set call forwarding. With an empty battery or switched off mobile station is the Participant also not reachable if he forgets the diversion to disable. At the very least, when accepting a conversation, you get through the mobile station higher Telephone costs.

This Problem is due to a time delay Call diversion can be avoided. In a menu this is for example with at Do not sign up ". Only with a certain number of ringtones the redirection becomes automatic activated. If the called party is in the office, then He, if he takes fast enough the landline call, a cost-effective Landline call answer. If the participant is on a business trip Time Lag the conversation the mobile station forwarded. The number of ringtones is adjustable. In the Setting a few ringtones, for example two, the problem is that the called party always close of the phone. For many ringtones, for example, six or more, however, there is the problem that the diversion in the case of business trip It takes a relatively long time, because it is not only to consider the time of the set ringtones, but also the not negligible relatively long connection time over a mobile network. This can cause the caller the Impression has that the callee is not available. Also the acoustic signal break during the Cellular connection can irritate the caller because he is in this a few seconds of continuous time no dial tone hears what lead to it can make the caller hang up before the called party reacts can.

Known is also a call diversion "At This can Cheap be to make a phone call to another phone, for example to divert a freelance employee.

Is possible also several phones of a known telephone system at the same time For example, if the participant works at home and for this a private and a service telephone, each with a telephone number. Does he want for both areas always be reachable, he must always both phone numbers change over what is uncomfortable.

Also It is known that a mobile terminal operated with a so-called "home zone" function becomes. The mobile network leads Here, a location recognition of the participant or a residence recognition to determine if the subscriber is within the "home zone" the "home zone "is like a landline number. Is this called when the subscriber is outside this zone is located, then an automatic call forwarding, the normal, more expensive tariff is valid. Although the participant is always everywhere reachable, but it must also always used the mobile station become.

Of the Invention is therefore based on the object, a method according to The preamble of claim 1 to be designed so that a call diversion in conveniently done.

These Task is inventively characterized solved, that an automatic diversion by sensor detection of the whereabouts a participant takes place.

By the measure according to the invention is eliminated manually switching a telephone. An activation or deactivation the call diversion can not be forgotten because of the whereabouts automatically detected and the call switching automatically switched on or can be switched off.

The Invention relates not only to telephone systems but can also be used in direct connection with exchanges. For example the exchange has the character of a so-called "Next Generation Network "or includes so-called VoIP softswitches ".

A Call diversion can be set to "immediate", the participant is not dependent on the less optimal "no reply" function.

The subscriber can easily switch several telephones at the same time automatically. A multiple, manual call switching is eliminated.

The Detection can be advantageously applied to a residence area, especially related to a job of an employee. Thus, an automatic changeover to his "mobile phone" always ensures that, for example, customers in a safe manner with the employee can be connected. An implementation of the measure according to the invention is relatively easy to implement. Especially if for a preferred embodiment the invention of a non-contact Detection of an arrival and a leaving of the participant of a Occupied by a sensor network. Leave the Participants, for example, his office, is going through a particular zone at that moment, especially through a door, a call diversion activated. A deactivation of the same takes place while reversing this zone. Here it is particularly useful to detect the direction of movement to avoid faulty circuits.

Zweckmäfßigerweise is at least one terminal as a telephone device with a landline connection. This can be on a mobile station or even on a second landline terminal an external telephone or even an internal telephone of the same Telephone system to be diverted, for example, in the absence to perform an internal redirect to another employee too can.

To a further advantageous embodiment of the method according to the invention is provided that the principal of a mobile radio terminal is positionable, in particular fastened or attached is. The principal can in the mobile station be directly integrated or only indirectly attached, for example, on a protective cover the mobile terminal.

According to one appropriate training of Invention, the identity sensor tells about that Sensor network a computer with a detection, whereupon the computer a central facility of the telephone system instructs a connection, in particular an extension of the subscriber to a previously entered Redirect number, in particular a MSISDN phone number. Many telephone systems are already connected to a computer through a base station. An implementation of the invention is therefore easy because a compound a sensor network with the computer or a computer network easily is to implement. Both cable connections and serial, parallel, USB interfaces or an infrared or a wireless connection come in the Computer interfacing with the sensor network in question. It is not absolutely necessary to change the hardware of the telephone system. A Adaptation and retrofitting can easily by a computer software that accesses the telephone system carried out become.

If at least one identity sensor at a single and / or Output area is housed, especially on a door frame or at least near him is arranged, bypassing the call forwarding is practically impossible if this is wanted.

A Motion direction detection of a variant of the invention can, for example by two at a certain distance arranged one behind the other identity sensors be done, with both sensors must be activated to to generate an activation or deactivation signal. The chronological order the individual sensor signals provide information about the direction of movement and thus, whether an activation or deactivation signal is required. The call diversion can be based on an identity carrier for movement direction detection, in particular an ID or RF carrier, and an identity sensor respectively.

Further advantageous developments of the invention are characterized in the subclaims.

The Invention and other advantages thereof, will be with reference to the figure description explained in more detail.

It shows:

1 illustrated by means of a small telephone system (ISDN) the call forwarding invention.

The following are the in 1 illustrated landline telephones INT 11, INT 12, for example with radio transmission to a base station B with connection to a PC, simply referred to as telephones. A mobile station H is simply referred to as a mobile phone. A fax machine is called a fax.

The plant consists of: INT 11: first phone INT 12: second phone INT 21: fax

In addition, the following are used for explanation: H: mobile EXT 1: private telephone EXT 2: private fax

On a doorway 30 an office door S or in particular an RFID or ID carrier is attached to an office door or in its vicinity, which is designed to recognize an identification carrier T and its direction of movement. The identification sensor S is coupled to the PC via, for example, a radio link or a receiving device E.

In a first case, an employee to whom the first telephone INT 11 is assigned should always be reachable by telephone - even on a business trip. The call switching is set so that when the employee is out of the office 31 is to be redirected calls on his phone INT 11 to the phone H. Here, the identification carrier T is arranged on the mobile phone H.

When leaving the office 31 as soon as the employee with his mobile H through the door 30 is activated, the call forwarding activated, the PC controls this process and forwards corresponding commands to the base station B. When the employee returns in the opposite direction through the door 30 go and the office 31 enters, this call forwarding is deactivated.

2 illustrates this first case.

Analogous this applies to a data reception, for example, an SMS. So if you are, for example a specific extension sends an SMS (SMS in the fixed network), can this also to any terminal, such as a mobile phone, be redirected.

3 illustrates a second case in which a call is automatically redirected internally to the second phone INT 12 of a second employee in the absence of the employee. This is also the identification carrier arranged on the mobile phone.

Calls or data information can also be redirected to external landline devices automatically, like the 4 to 6 demonstrate.

A call for employees with the telephone INT 11 can be automatically redirected to a private telephone EXT 1 ( 5 ). As soon as he drives home with his mobile H (house 33 ) and is at home, he can take private calls from the phone EXT 1. This can be done in conjunction with a timer. This can exclude certain times and / or days. For example, so that switching is possible only after a certain time (17:00), so that a lunch break is not taken into account. For example, a setting can be made so that the employee can automatically receive diverted calls only on Saturdays and in the absence of office. This can be combined with a call divert on no reply, so that if the employee is not in the office or at home, they will be redirected to their mobile H.

Also any other combinations with an option "when occupied" are available with the or absence control possible.

Any diversion of a data transfer is possible. According to the invention, an office fax INT 21 can automatically be switched to an external fax EXT 2 in the case of office absenteeism, so that, for example, faxes arrive at home on weekends and in the absence of office space ( 6 ).

The described sensor device according to the invention, which is connected to the PBX and the PC, so is used for execution the call diversion according to the invention. Means for automatic diversion by the sensor detection according to the invention The location of a person may have a hardware and / or a software, at least one interface between sensor device and PC and / or the telephone system as well as the sensors including one Be evaluation electronics.

The Software to be loaded into the PC, on the one hand, communicates with the sonsor device (Identification sensor S) and on the other hand causes a control the telephone system and the activation or deactivation of a Call diversion, such as described above.

The invention is not limited to the illustrated examples. Call diversions can be combined with each other. Also, call diversion may be with other data and / or voice communication devices or another telephone be used.
