Method and system for communication routing

0001The present invention relates to a method and system for directing communication from a first communication participant to a second communication subscriber.

0002Such methods and systems may for instance in companies with a variety of office workstations use find.

0003Many users of communication devices to keep not permanently at a fixed place. Still want such Users continually receive all incoming communications. Around under the same e-mail address or the same number at different locations to be accessible, you have to off usually on one computer and another computer Sign in. Alternatively, it is possible a diversion to program by hand or an operational terminal constantly carry with you.

0004With the known solutions, however, is only with great effort for the user possible, at any location, such as the domestic living room or office, car, fixed office workstation or a temporary laboratory workstation to be accessible from one address or number. at known mobile terminals takes place without prior provision also interference from incoming communications in places such as meeting rooms, canteen or toilet.

0005Thus, the present invention is based on the object, a method and a system for conducting communications provide that the disadvantages of the prior art avoids.

0006This object is achieved by a method for routing communication achieved according to the independent claim. 1 Another Achieve the object, a system for conducting communications is according to independent claim 19th Advantageous Further developments of the invention result from the dependent Claims.

0007The present invention relates to a method for conducting of communication from a first communication participant to a second communication subscriber, comprising the steps<ul><li>Check the presence of the second communication subscriber at a staging point or a suspected whereabouts and / or determining the place of stay or a suspected whereabouts, and</li><li>Directing the communication to at least one of a Receiving the communication on the whereabouts or suspected Pied available means of communication.</li></ul>

0008When communicating according to the present invention may involve electric to any kind of telecommunications or act communications, however, preferred to voice communication. In particular, it emails, faxes, telexes, Phone calls, video calls, Microsoft (TM) -Netmeeting calls forwarded immediately messages (so-called Instant messages), or personal loudspeaker announcements includes. Communication participant within the meaning of the present invention does not have two communication participants may be limited, but also a group of Communication stations include that communicate with each other, or, for example, two or more groups, communicate with each other. When the means of communication it is, for example, devices for input and / or Output, telecommunication terminals and monitor terminals. Preferably, in the communication means a car phone or a portable cellular phone. Car phone refers here generally to mobile stations in vehicles, particularly permanently installed. In the residence for the purposes of the present invention it is not just a static fixed location, but for example also by one gear, the user just Start running or a moving vehicle. Not always can the whereabouts safely conclude, but often there is evidence, rules or directions on where to the second communication subscriber is located. This evidence, Rules or instructions can of technical devices are processed. The fact that these devices thereby also once can decide wrong, is to "stay or suspected whereabouts "are expressed. Under Circumstances can also buy several whereabouts in question come to which the communication sequentially or simultaneously can be conducted. Directing the purposes of the present Invention relates to the way, in particular the place the source and location of the sink of a communication, and is not be understood primarily in terms of electrical conduction. A Line, for example, by a call forwarding to each nearest phone done.

0009Preference is given to information on the whereabouts or presumed location of the second communication subscriber obtained and / or evaluated. Considering Such information may be decided to what means of communication Communication for the second communication subscriber is passed. So preferred is the directing selecting at least one communication means advance, the selection can be made right before communication arrives for the second communication subscriber.

0010In a preferred embodiment of the present invention be attached to the whereabouts or suspected whereabouts the second communication subscriber available Means of communication determined.

0011In a further preferred embodiment of the present Invention is, if no means of communication available and / or has been determined, the communication to a Storage medium diverted. The storage medium may , for example, to an answering machine. Answering machine is not here at the terminal for the home be understood, but also included other solutions, as for example, under the name and voicemail Voicemail are known, include. Instead of a storage medium can also be a device to automatically reply, For example, with an announcement or a to first communication subscriber sent message text, to Use come.

0012In another embodiment, in the absence of second communication subscriber set call forwarding are, in particular a call diversion to a portable cellular phone. In the presence of the second communication participant can call divert be repealed.

0013Ends the presence of the second communication node on a specific location, so it can be provided that communication is no longer at this location is redirected. It is conceivable that the communication in such a case is redirected to another location, at the second communication subscriber which is then located or from which it can be assumed that the second Communication user goes there. The latter is particularly advantageous when at the place to which the second communication subscriber goes, no suitable means for detecting the presence or proximity of the second Communication subscriber and to change the destination of the Communication is available.

0014In a further preferred embodiment, the Line of communication automatically. This means that the location of the second communication subscriber automatically is determined and a line of communication automatically, ie without a choice, to the second Communication subscriber takes place.

0015In an advantageous development can also, if a Communication request at a first communication means was not complied with after a predetermined time, for example, if even after three rings of a phone no lifts, the communication request to another means of communication will be redirected to suspect from the is that the second communication subscriber is with him staying. Alternatively or additionally, when a communication request not met after a predetermined time was, the communication directed to a storage medium will.

0016In a further embodiment, the identity, or Identification of the first communication subscriber, for example, his telephone number, the automatic decision, whereas the Communication is conducted, influence.

0017In an alternative embodiment, the line is carried out of Communication due to a selection by the first communication subscriber, where this means of communication available be communicated. It is conceivable that the first Communication participants all available means of communication or just a selection of the available means of communication be communicated. The first communication participant can thus determine to which means of communication at the second communication subscriber he directed communication would like to have.

0018In a further preferred embodiment of the present Invention go into the determination of the location the second communication subscriber data regarding the habitual residence of the second communication subscriber and / or the time. Especially when leaving the second communication subscriber a particular residence can be time dependent, in particular times of the day, be determined, where the communications are diverted should. For example, take into account that the second communication participant usually every Day is in the cafeteria at 9:00 am, or that, if He leaves the office workplace in the late morning, mostly in the library is within a quarter of an hour later.

0019In another embodiment, the location is a the second communication subscriber associated communication agent certainly. To determine the whereabouts can further information, in particular information a second communication stations associated Communication means, such as a mobile radio terminal, be considered.

0020In one development of the present invention, Using a biometric recognition method People in the residence or location of the suspected second communication subscriber intended or his presence at a staging or suspected whereabouts checked. Means that the biometric methods recognize second communication subscriber, this means of communication are on places where the second communication subscriber would be achievable, assigned. communication for the second communication subscriber is correspondingly passed. Biometric methods permit detection, For example, using the fingerprint, on the basis of Appearance, especially the facial features, based on the fundus, using the voice and / or on the basis of body odor. The recognition marks with identification function, which are firmly connected to the body, in particular of implanted chips to biometric methods be expected according to the present invention. Prefers is staying in a room at a workplace or determined in the vicinity of a communication means. For recognition can an action of the second communication subscriber be necessary, for example, that he prescribed Words speaks, a finger on a sensor or in a Looking camera.

0021In another embodiment of the present invention is using an access control device of Whereabouts or suspected location of the second communication subscriber determined or presence on a Whereabouts or suspected whereabouts checked. For the access control means are different ways usable. Thus, limiting access / control by mechanical locks and keys. In some systems, the key is not to do not only or from the Castle, but also by its owner from. In this case, are not only detected when using the key that it is an authorized access, but also to infer the person. Thus, in motor vehicles a key are used to the driver before Getting to identify and its stored personal Settings such as setting of the mirror display. Further, the access control unit with machine readable objects such as maps or cards, for example, with barcode, magnetic stripe or chip, done. From the information, where the second communication subscriber was detected, can often be closed, whereas he goes. Accordingly can get the incoming communication be guided (to).

0022Preferably, the access control device of a vehicle for the presence of the second communication participant include, in particular its presence in the driver's seat. includes the access control device of a vehicle For example, locking and locks, central locking and / or immobilizer. The vehicle access control device in addition to the as well as on-board computer and control units may have derived an appropriate information and / or an activation command to a mobile radio terminal in the Vehicle on. If not the case, the mobile station is operational.

0023In a further development of the vehicle transmitted to the mobile station a PIN (Personal Identification Number), in particular the PIN of the second communication subscriber to a SIM that is inserted in the mobile terminal in the vehicle is. The SIM includes mutatis mutandis same with other Standards as the GSM (Global System for Mobile Communications) Standard, for example USIM in UMTS (Universal Mobile Telecommunication System), a.

0024Preferred is a vehicle in the presence of a known Communicating party checked. It can in a Embodiment, the presence of the second communication participant is closed in the vehicle from the fact that to him associated vehicle key in an ignition lock is. Preferably, the presence of the second communication subscriber based on a key, in particular a Vehicle key, recognized.

0025In one development of the present invention, Use of a method for determining the position of the whereabouts or suspected location of the second communication subscriber determined or presence on a Whereabouts or suspected whereabouts checked. location in the sense of the present invention, both absolute and relative terms with respect to a device, in particular a telecommunication device or means of communication meant. Partly it may be sufficient to close the the user or his agent assigned to a facility determine the direction with respect to the establishment is often irrelevant.

0026In the method for determining the position is preferably to electronic processes, such as techniques such as radar, direction finding, radio beacons, satellite navigation as GPS (Global Positioning System) or techniques for location-aware Services LCS (Location Services) in mobile as OTD (Observed Time Difference) and based procedures. at Systems with short range can already the occurrence a transmission, possibly coupled with a minimum field strength or a maximum path loss, in so suggest small distance between transmitter and receiver, that the position determined with sufficient accuracy can be.

0027More preferably performs the second communication subscriber a device with them which allows position determination. This can, for example, a mobile radio terminal Be that supports location-based services or positioning. Depending his whereabouts, the Means the line of communication, especially incoming Communication as incoming e-mails, phone calls and Faxes influence. Thus, in a mobile terminal about phone calls depending on the location, possibly in combination the path followed so far and / or date / time to nearby landline devices, the mobile phone terminal are directed itself or on an answering machine.

0028When the second communication subscriber of different Devices from communicating, but with outgoing communication is known to the system as a user, can have its own Identity instead of the devices actually used be reported to the network. If an employee, for example, like from the laboratory, where he worked on his temporary work was identified, the callee can its main phone number instead of the number of laboratory workplace his name are received and / or.

0029When the device, the last, the presence or near the user has recognized, is movable, for example, in a device in a vehicle, it can also be location-dependent be where the communication when leaving the residence is passed. Preference is given to such Case means used for position determination.

0030The initially stated object is also a system for Line of communication from a first communication participant dissolved to a second communication subscriber. The system includes<ul><li>Means for checking the presence of the second communication subscriber at a staging or suspected Whereabouts and / or determining the place of stay or a suspected whereabouts, and</li><li>Means for directing the communication to at least one for receipt of the communication of the whereabouts or suspected whereabouts available means of communication</li></ul>on.

0031The invention further relates to a mobile radio terminal for use with a method and / or according to the invention for use in a system according to the invention.

0032Furthermore, the invention relates to a SIM for use with a The method according to the invention and / or for use in a system according to the invention. The invention also relates to an information link between an access control device a vehicle, especially a lock, and a mobile radio terminal in the vehicle for use with a method of the invention and / or for use in a system according to the invention.

0033To redirect the communication suited to facilities, which affect the way and / or destination of communications, be suitably influenced. to be influenced Such Facilities can a server instance, for example, Mail server, switching systems, particularly for telephony, his or router. If the device, the information on the location of the user evaluates, and the means which influenced path / destination of the communication, are separated, signaled the closing on the presumed whereabouts Means the device that influences the way / destination, where the user resides probably. signaling may also include a plurality of candidate places. They may include, for example, phone numbers.

0034The invention will be hereinafter with reference to the accompanying Drawing further explained with reference to embodiments. The features illustrated there and the already Features described above can not only in the above Combination but also individually or in other combinations be essential to the invention. It shows:<dl tsize="7" compact="compact"><dt>figure 1</dt><dd>a schematic representation of an embodiment of the present invention.</dd></dl>

00351 shows schematically a company with several office workstations. In an office, there is a telephone set 10. It is assumed that the master A Company mainly working on his office workstation, to temporarily but also in an electronics lab and in a mechanical workshop is staying, where each telephone sets 11 and 12 are available. A device 1 to recognize a time t₀That Master A mechanical workshop enters. The device 1 signals the PBX 3 via a transmission 2 that Master A in mechanical workshop at the time t₀ was detected. The PBX 3 knows the associated number of the local telephone set 12 has no information about it, whether the master A at a time t> t₀ always staying in the mechanical workshop. In a later Call from an employee of B whose apparatus 13 passes from PBX 3 the call therefore first on the apparatus 10 in the office to Master A. If the call is not there within the predetermined time of, for example, 15 seconds accepted, so employee B is in the display his apparatus 13 redirection "-> mechanical workshop" appears and the call is diverted in the mechanical workshop. If the call is not there within a further time interval, for example, 15 seconds is accepted, is to an answering machine 14 diverted. When the Master A in his office returns, it recognizes the device 1 and replacing effective after 15 seconds Call forwarding in the mechanical Workshop by an effective after 15 seconds diversion the answering machine 14. In the electronics laboratory not only recognized the access, but also the presence. embarks Master A the electronics laboratory, recognizes this device 1 and signals the PBX 3 that the Master A present there. Calls for Masters A will now immediately directly to the local telephone 11 put through. In the display of the caller "appears -> Electronics laboratory ". After for example 15 seconds, a unanswered call to the answering machine 14 passed. When the Master A leaves the electronics laboratory, signaled the device 1 so the PBX 3. Now Calls for Master A are fed back into the office and if they are not answered there within 15 seconds are, they will turn to the answering machine 14 redirected.

0036In a further embodiment of a company assumed in the staff individual office workstations and Community laboratory workplaces where they have to share workstations to several. On a multi-user computer workstation, the Computer mouse a fingerprint sensor. Thus, the current users are detected. Depending on the detected user the relevant files to the user's available, and emails are for the respective user on this computer workstation passed. Given informed of the e-mail client of the multi-user video workstation the mail server. Further information the computer of the multi-user video workstation the telephone exchange system, which then calls for each current user on this workstation passes. This procedure saves the employees to log out of hand at the office workplace by the mail server and log on to the laboratory multiuser computer workstation. Furthermore, he does not always manually call forwarding reprogrammed to temporary work in the laboratory. For jobs, equipped with a camera are - for example, a webcam on the monitor for Microsoft Netmeeting - can by face recognition instead of the fingerprint of the employee even without contact be recognized.

0037In another embodiment, a nuclear Plant with a security area where the use cellular mobile communications because of shielding by thick Reinforced concrete walls is not possible adopted. The gears and Facilities of this range are equipped with video cameras to in case of failure to locate missing employees. With Support of video surveillance is the whereabouts of employees automatically determined by optical detection. In the Transitions there sometimes only speakers, partly hands-free, and in the rooms there are telephones. Calls will now be a function of the whereabouts of the desired Interlocutor in the hallway or room in question passed. If the called party in a staying space, rings there that the employees closest Phone, and the caller hears a ringback tone until the Call is answered. If the employee is in a Gang resides, the call to the appropriate gear is engaged, and the caller receives a signaling on the Display of his telephone set whether a simplex or a duplex connection. The caller, the space / transition number are displayed to the call was connected.

0038In a further embodiment, a couple has two Vehicles with car telephone and navigation system. The car phone has room for multiple SIM (Subscriber Identity Module) cards, called SIMs. The husband has a pair of twin SIMs, the wife also has a pair of twin SIMs and a further SIM for their portable cellular phone. Both spouses have in each car phone ever inserted one of her twin SIMs. They have the associated PINs (Personal Identification Number) entered. Each car phone has memorized the PIN, so that it automatically enters after switching on. If the SIMs are taken out of the car phone or when the power of the car phone interrupted was that PINs must be reentered. The married couple give potential callers the numbers of their twin SIMs. About a recognition means the car phones recognize the Presence of the users of the inserted SIMs. For example this can mounted above the footwell of the driver and passenger Sensors of similar to a dog's nose people based recognize body odor, take place. If the husband the driver's seat leaves, call forwarding is activated. Leaves it is the driver's home, at his home Landline diverted. If he leaves it to his company car park, so is redirected to its official number. If he leaves it at another location, it is a Voicemail redirected.

0039If the wife leaves the driver's seat, is a diversion connected. Leaving it to the driver's seat at home, is redirected to a home landline. Leaves she him, so is in their company parking lot on their business call number diverted. Leaving it at him a other place, so will be redirected to their mobile phone. Puts the wife on the passenger seat, then on their mobile phone redirected. Leaving it to the passenger seat Home is diverted to the domestic landline. Leaving it to him their company parking lot, so will their business call number diverted. Leaving it at him a other place, so remains redirected to their mobile phone.

0040Sets up the husband on the driver's seat, so the car phone is activated with its SIM, and call forwarding canceled. Sets up the wife of the driver's seat, so the car phone is activated with its SIM, and call forwarding be repealed.

0041At least one of the car phones can also be programmed to be it to date / time-controlled call forwarding changed, redirects eg after 21 pm to the voicemail box, so you will not be disturbed at home. If the car phone previously queries the current setting of call forwarding and stores, when there is the question over night for the SIM is not used and when it verifies the morning, if continues to be diverted to the voicemail box, it can, for example, at 7am restore the old setting. If it has been used overnight for the SIM in question his or the next morning, the evening programmed forward no longer exist, so the car phone is preferred do not change the current setting.

0042Benefits arising from the availability at one Phone number at home, on the road and at work, as far as one would be accessible without call forwarding manually must be programmed. Furthermore, one needs at home and on the work no mobile phone to carry with you, and is also less disturbed if you can not be reached would like. As a further advantage, the wife needs her cellphone not to get stuck in an automotive mount and again remove. This is especially for many short journeys, For example, to daycare and Shopping, practical.

0043In a further embodiment of a vehicle with a car phone and hands-free as well as a Driver went out with a portable mobile terminal. The driver has ever a SIM for the car phone and a SIM for his mobile terminal. Telephone numbers for SIMs are differently. The car phone is the phone number of the mobile radio terminal known. So that the driver is not always the new must enter the PIN for his SIM, the car phone, the PIN Save until the SIM is removed or the power supply the car phone is interrupted, for example, preventing theft. The potential callers is preferred know the number of the SIM for the car phone. The automobile recognizes via the ignition lock, the presence of the driver. When the ignition key is in the ignition, to incoming calls to the driver on the speakerphone reach the car phone. If the driver operates the ignition key subtract, to incoming calls on his portable mobile terminal are passed. This is achieved by the Car phone when the ignition key a diversion the telephone number of the portable mobile communication terminal in the Driver programmed. When the key is inserted into the ignition lock is, call forwarding especially for the will Voice service canceled, and when it is pulled out, is call forwarding set. The diversion, for some Services, such as SMS (Short Message Service), permanently to the mobile radio terminal the driver be set. With multiple SIMs the car phone and in several, distinct car keys this will work for several drivers. The driver give potential callers when their mobile phone number the inserted in the car phone SIM in, and the car phone passes depending on the car key for the associated SIM, IMSI (International Mobile Subscriber Identity) or Number to a (generally different depending on your SIM) Mobile phone number to or revoke the relevant call forwarding on. In wireless car keys, the procedure is also applicable. The concept car key is in this invention also car keys corresponding objects, For example, for contactless access control, lock in. The network operator can order a mess the callee by different mobile phones to avoid the driver, the driver's mobile phone terminal the phone identity, ie the so-called "Calling Line give Identity Presentation "of the car phone. For incoming but calls remain the phone number of the driver's mobile phones differently of the car phone.

0044This can be advantageously combined with the fact that the car phone or deactivated when leaving the vehicle is what for example at the turning off of the motor or the ignition, Removing the ignition key, shift the transmission to Park position, locking the steering lock, pull the Handbrake, release the belt, locking the vehicle, Activation of the immobilizer, activate the alarm system or placing a call forwarding in particular for the Language services for the SIM or if it supports multiple SIMs be, for all the car phone inlaid SIMs, can be moored. Conversely, if a beneficial owner Person boards the vehicle or starts what be made for example to the contrary actions can be turned on or activated the car phone. In this case, the ignition key as access authorization for the serve use of SIM and enter the PIN manually at replace time the car phone. For example, in be stored on-board computer, using what key the car phone is to be ready, and the Board computer can optionally appropriate information Tell the car phone. The information can at more, distinguishable keys an indication of the associated Communication Participants included. Thus, the car phone For example, the associated profile with ring tone, etc. Select, and at several SIMs to the vehicle key Select the appropriate SIM. It is also conceivable, for example, that a board computer enters the PIN for the user. at multiple, distinct vehicle keys and more SIMs, for example, the on-board computer and in each case the Enter the vehicle key matching PIN.

0045Instead of multiple SIMs or in combination with several SIMs, it is also conceivable that a SIM several numbers or IMSI support, wherein for example, by different PINs respectively the associated number and IMSI can be selected. This allows several drivers also use the procedure if the car phone only can take SIM card.

0046In the simplest case therefore come as a means of communication, at least a car telephone and a portable cellular phone in Question. If the absence is detected or another Criterion for the second communication subscriber preference make phone calls using the portable cellular phone, met is to be directed to the telephone number of the car phone telephone calls redirected to the portable cellular phone. In order to it is meant that one of the phone number of the car phone assigned Call forwarding refers to the portable cellular phone. This does not mean that the call actually the portable cellular phone arrives because of the number the portable cellular phone, other diversions, for example, to an answering machine set, be. If the presence of the second communication subscriber is detected on the car phone or another criterion that the second communication subscriber preferably above is phoning the car phone, met, on the Number of the car phone directed phone calls possible also passed on the car phone. This possibility is not, for example, where, when, where the Car phone is, no coverage exists.

0047The diversion in the absence can eg be achieved by that when leaving the car phone fixed forwarding set to the portable cellular phone and vice versa in the Check fixed forwarding is canceled on the car phone.

0048In a variant, a related rerouting of the call number the car phone to the telephone number of the portable cellular phone set up, in particular for non-availability. If upon reaching the vehicle, which on criteria such as Unlocking the vehicle and / or the steering lock, disabling the alarm, picked the immobilizer, seat belts, Switching on the ignition and / or starting the engine can be made, the car phone is activated and responds to incoming calls, the phone of the second Communication subscriber via the car phone. If after is leaving off, accesses the conditional call forwarding for non-accessibility and routes the call to the phone number of the portable cellular phone further.

0049In one development, the possibility is also provided, that, particularly in non-accessibility (eg if the second communication subscriber no network coverage has), in busy or / and if no answer (for example, when the second communication subscriber does not pick up) the first communication subscriber to a storage medium, in particular a mobile box, is redirected. Preference is given for the number of Car phone and the telephone number of the portable cellular phone the same voicemail used. would be in a GSM network according to the prior art to your voice mail at least of one of the two communication means from the input of a PIN required. In a preferred embodiment but assigns the network operators an answering machine, in particular a voicemail, the two phones so on, that the query at least from its own network, no additional Identification such as typing PIN requires.

0050The following call forwarding could be set, for example:<sl><li>Car Phone:<ul><li>if not accessible to the portable mobile terminal</li></ul></li><li>A portable mobile terminal:<ul><li>if no answer after a predetermined, short time to voicemail</li><li>if not accessible to voicemail</li></ul></li></sl>

0051In the exceptional case that at a drive for an incoming Call the car phone has no reception, but that portable cellular phone service coverage, the portable cellular phone is ringing only briefly, and then the first communication subscriber redirected to voicemail.

0052In a further embodiment of a hospital assumed, in which the use of mobile phones is prohibited. In the closed psychiatric ward are under video surveillance, the rooms and additions. Access is only authorized persons granted. The authorized persons identified by their facial features. The access control system recognizes characterized with high reliability the current Whereabouts of the base doctor. Him calls in question are now brought into the room, to the access control system recognized as a residence, for example station room, Treatment room, kitchenette or consulting room, etc. This is the medical staff more accessible than with the pagers in use today, which are only a call request signal and then a callback from a close require convenient phone.

0053In a further embodiment of a mobile radio terminal assumed that for positioning suitable is. It was also a memory of an allocation residence zones available there landline Telefonanschl ust and allows fax connections. This Memory is suitable programmable. The mobile radio terminal and / or the mobile network measure again the location the mobile radio terminal. Depending on the residence Call forwarding and Fax diverts be changed. A Change a call forwarding may include actions such as Setting, setting, picked, delete a call forwarding or replacing the current target by a new Aim. If the user is in his office, calls on the local telephone directed. Faxes are on the Fax headed the office. If the user in a foreign Office, is to be mobile terminal or a telephone conducted in a foreign office. If the user in a Labor is, calls are routed to the telephone in the laboratory. If the user leaves the company, calls on the mobile radio terminal conducted. If it relates to the auto route located between company and at home, is to the car phone passed. Faxes are routed to the fax memory, which may be web-based and / or in the mobile radio terminal may be located. When parking at home leaves towards apartment, the calls can be heard on the Mobile radio terminal conducted. Faxes are on the domestic Fax modem passed. When he enters his apartment, the Calls directed to the domestic landline phone. If the Users in the cafeteria, in the meeting room, in the toilet his department or in the church of his parish resident, calls are routed to voicemail. If in particular based on location and velocity profile it is recognized that the mobile radio terminal on the Route of the urban bus or coach is moving in which the use of is prohibited from mobile handsets, calls routed to voicemail. This call forwarding is again canceled when the user leaves the bus route.

0054As a further embodiment, the use of the the present invention in a company with multiple Staff explained. An employee has an A contactless readable staff ID. The associated Card readers question the statements by radio from and thereby identify the employee. Employee A is not at work, but at work a Employee as a card reader at the workplace of Employee B, for example, at its networked computer, recognizes the close of staff A and gives the network as Position of the employee A's workplace employee B known. Calls and e-mails with high priority for A staff are now to work of employees B passed, as long as the card reader at the workplace of Employee B detects the proximity of the employee A. at A message arrives for an employee A appears on the Screenshot of employee B for example, the message: "New, Urgent Message for identifier A. Do you want the Read message now? "If" Yes "is again the presence checked by employees A and then retrieved his password. While e-mail is displayed for employee A, is his presence checked regularly. If the window the employee's screen B is not closed, before an employee A workplace of employees B leaves, the window is automatically when leaving closed. When a call for employee A will appear on Terminal of an employee B in the display both Identification of the caller, if available, as well as an identification restriction in the form of name and / or Phone. The caller gets as far as possible, the Redirection is also displayed.
