Description

CALL MANAGEMENT

TECHNICAL FIELD OF THE INVENTION

The invention concerns a method and a telephone management system associat- ed with a vehicle. More specifically, the invention concerns a mechanism for managing incoming telephone calls to one or a plurality of telephone subscribers connected to the telephone management system in the vehicle.

BACKGROUND A driver in a vehicle is at risk of being called on his mobile telephone, including while driving the vehicle.

"Vehicle" refers in this context to, e.g. a goods vehicle, long-haul semi, car, emergency vehicle, vessel, van, motorcycle, tracked vehicle, bus, amphibious vessel, hovercraft, helicopter, airplane or similar motorized manned mode of transporta- tion adapted for land-based, sea-based or air-based geographic movement.

Using the mobile telephone while driving poses a safety risk, as the driver can be distracted and risk a shift of focus from the driving situation to keypad manipulation on the mobile phone. At present, non-hands-free telephone conversations are forbidden while driving in the majority of jurisdictions in Europe (allowed only in Albania and Malta, in addition to Sweden).

For this reason, a vehicle often has a telephone management system that enables the driver to, for example, answer an incoming call by pressing an answer button disposed in some easily accessible location, e.g. on the steering wheel, and also comprising a loudspeaker/microphone so that the driver can answer the call with a minimum of distraction from the driving situation.

However, a driver sometimes has two or more mobile telephones, e.g. a work telephone and a private telephone. Alternatively, the driver can have different sub- scriptions on a single mobile telephone, such as a private subscription and a work subscription. Furthermore, a plurality of drivers with different mobile telephones and/or subscriptions are sometimes present in the vehicle simultaneously, driving it in shifts. It is currently not possible to connect more than one telephone to the telephone management system at a time. The driver is thus forced to choose which mobile telephone is to be connected. The mobile telephone that is not connected must be managed by the driver in addition, which can constitute a traffic hazard as well as a violation of the law in many countries, or he can decline to answer it. But even if a second mobile telephone could be connected to the telephone management system in the vehicle, a problem would arise when the telephone management system has connected a first telephone and an incoming call arrives for the second telephone.

Existing solutions for telephone management systems in vehicles are incomplete, and there is an extensive need for improvement measures to avoid the risk of missing calls without threatening traffic safety.

SUMMARY OF THE INVENTION

One object of this invention is consequently to enable the management of a plural- ity of telephone calls on one or a plurality of telephone subscriptions in one or a plurality of mobile telephones in a telephone management system in a vehicle in order to thereby solve at least one of the foregoing problems and thus achieve a vehicle improvement.

According to a first aspect of the invention, this object is achieved by means of a method in a telephone management system in a vehicle for managing incoming telephone calls. A first telephone subscription and a second telephone subscription are connected to the telephone management system. The method comprises the establishment of a first telephone call over a first telephone connection be- tween the first telephone subscription and a first telephone. The method further comprises the receipt of a request to establish a second telephone call over a second telephone connection with a second telephone. The method also comprises a representation of the received request in order to notify the vehicle driver there- of. The method further comprises the detection of a choice made by the driver to indicate how the received request is to be managed. The method also comprises the management of the received request in accordance with the received choice made by the vehicle driver.

According to another aspect of the invention, this object is achieved by means of a telephone management system in a vehicle for managing incoming telephone calls. A first telephone subscription and a second telephone subscription are connected to the telephone management system. The telephone management system comprises a communication module, arranged so as to establish a first telephone call over a first telephone connection between the first telephone subscription and a first telephone, and arranged so as to receive a request to establish a second telephone call over a second telephone connection with a second telephone. The telephone management system further comprises a processor circuit arranged so as to initiate a representation of the received request in order to notify the vehicle driver thereof. The processor circuit is also arranged so as to detect a choice made by the vehicle driver indicating how the received request is to be managed, and further arranged so as to manage the received request in accordance with the received choice made by the vehicle driver. The telephone management system also comprises an indicating device arranged so as to notify the vehicle driver of the received request to establish a second telephone call over a second telephone connection with a second telephone.

Connecting an additional subscription to the telephone management system in the vehicle and allowing the telephone management system to manage incoming calls by collecting a driver choice as to how the incoming call is to be managed enables a plurality of telephone subscriptions to be managed, and the driver can use the telephone management system to manage telephone calls in the vehicle. An improvement of the vehicle is achieved thereby.

Other advantages and additional new features will be evident from the following detailed description of the invention.

DETAILED DESCRIPTION OF THE INVENTION

The invention is defined as a method and a telephone management system for managing incoming telephone calls in a vehicle, which method and telephone management system can be realized in any of the embodiments described below. However, this invention can also be implemented in many different forms, and is not to be viewed as limited by the embodiments described herein, which are rather intended to elucidate and clarify various embodiments of the invention.

Additional aspects and features of the invention can be evident from the following description when considered in connection with the accompanying figures. How- ever, the figures are to be viewed only as examples of various embodiments of the invention and are not to be viewed as limitative of the invention, which is limited solely by the accompanying claims. Furthermore, the figures are not necessarily drawn to scale and, unless otherwise specified, are intended to illustrate aspects of the invention conceptually. Figure 1 shows a vehicle 100. The vehicle 100 comprises a telephone management system 110.

The telephone management system 110 is arranged so as to connect a first telephone subscription and a second telephone subscription. In certain embodiments, two or more mobile telephones can be connected to the telephone management system 110. In certain embodiments, one mobile telephone with two or more subscriptions can be connected to the telephone management system 110. The telephone management system 110 is also arranged so as to manage two or more ongoing or incoming telephone calls to the same mobile telephone.

The telephone management system 110 can establish a telephone connection based on, e.g., any of the following technologies: Global System for Mobile Communications (GSM), Enhanced Data Rates for GSM Evolution (EDGE), Universal Mobile Telecommunications System (UMTS), Code Division Access (CDMA), (CDMA 2000), Time Division Synchronous CDMA (TD-SCDMA), Long Term Evolution (LTE), LTE-advanced; Wireless Fidelity (Wi-Fi), defined by the Institute of Electrical and Electronics Engineers (IEEE) standards 802.11 a, ac, b, g and/or n, Internet Protocol (IP), Bluetooth and/or Near Field Communication, (NFC), or a similar communication technology according to various embodiments.

Figure 2A shows an example of an interior of the vehicle 100, containing a telephone management system 1 0. In certain embodiments, the telephone man- agement system 110 can comprise a display screen 120, a loudspeaker 130 and/or a microphone 140, according to certain embodiments.

The telephone management system 110 is arranged so as to connect a first telephone subscription and a second telephone subscription. Furthermore, an estab- lishment of a first telephone call over a first telephone connection 215 between the first telephone subscription and a first telephone 210 can [sic]. The telephone management system 110 can also receive a request to establish a second telephone call over a second telephone connection 225 with a second telephone 220. Said request can be made to the first telephone subscription and/or the second telephone subscription.

When this occurs, a representation of the received call is performed in order to notify the vehicle driver thereof. For example, the representation can be made on the display screen 120, which will be further exemplified in the presentation in Figure 2B. The representation of the received request can also be made via the loudspeaker 130 by means of a audio signal or voice message, by means of a lamp or diode that emits a light signal, by means of projecting information on a portion of the vehicle windshield, by means of vibrations in a vibrator disposed in, for example, the driver's seat, or by means of a combination of these or similar representations. The driver can thus make a choice as to how the incoming call is to be managed by the telephone management system 110. This choice can be made via, for example, a button, toggle, keyboard, dial, software button, voice instruction or in another similar manner via a suitable input device. The driver can, for example, choose to accept the received call, ignore the received call, refuse the received request and/or place the incoming call in a call queue. This choice indicates to the telephone management system 110 how the incoming call is to be managed, after which the telephone management system 110 carries out the wishes of the driver.

The connection and management of a plurality of telephone subscriptions to/of the telephone management system 110 are thereby enabled, whereby the driver of the vehicle 100 can connect a plurality of telephones and or telephone subscriptions to the telephone management system 110 and use it to access, for example, a telephone number that is stored in said respective telephone or telephone subscription in a traffic-safe manner. Figure 2B shows an example of how a presentation of an incoming call can be made. A presentation indicating to the driver that someone is calling and optionally who is calling is shown in the enlarged depiction of the display screen 120.

In this example, the driver is given three possible choices: to accept the call by touching a first input device 125-1 , to ignore the call by touching a second input device 125-2, or to send a busy signal by touching a third input device 125-3. Other alternatives are also conceivable, such as putting the incoming call in a call queue. In certain embodiments there can be a pre-selected standard setting that can be configured so as to, for example, choose the option of ignoring the call if the driver makes no choice, or if no choice is made within a given time. It can be pointed out yet again that the illustrative example of how an incoming telephone call is conveyed to the driver is only one of many conceivable examples of how information concerning the incoming call can be provided to the driver. It is also conceivable that corresponding information could be given to the driver via, for example, an auditory interface. Figure 3 shows an example of how a call to/from the external telephones 210, 220 is managed by the telephone management system 110 in the vehicle 100.

In this example, a first telephone call is established with a first external telephone 210. Said first call can be initiated by the first external telephone 210, or by the driver from one of the driver telephone subscriptions connected to the telephone management system 110.

In this situation, a second telephone call can arrive from the second external telephone 220. This incoming telephone call can be to any telephone subscription connected to the telephone management system 110, which is engaged in the first call with the first telephone 210, or to another subscription.

The driver is now notified of the incoming call, e.g. in any of the ways described above under the presentation of Figure 2A and/or Figure 2B. The driver now has an opportunity to make a choice via an input device 125, such as accepting the call, ignoring the call and/or sending a busy signal.

The drive now has an opportunity to choose how the incoming call is to be managed and to mark it as an active or passive choice. The telephone management system 110 is then arranged so as to receive the choice made by the driver via the input device 125 and manage the incoming telephone call in accordance with the choice made by the driver. If the driver chooses to accept the incoming second call, then the first call with the first telephone 210 is concluded, and a new second telephone connection is established with the second telephone 220.

Figure 4 illustrates an exemplary embodiment of the invention. The flow diagram in Figure 4 clarifies a method 400 for managing incoming telephone calls to a telephone management system 110 in a vehicle 100. The telephone management system 110 is arranged so as to manage telephone calls, such as incoming telephone calls. The telephone management system 110 is arranged so as to connect a first telephone subscription and a second telephone subscription. According to certain embodiments, two or more mobile telephones with each their own telephone subscription are connected to the telephone management system 110. According to certain embodiments, one mobile telephone with two or more subscriptions is connected. The telephone management system 110 can also be arranged so as to manage, for example, two calls to the same subscription, or to different connected subscriptions.

To enable the correct management of incoming telephone calls to the telephone management system 110, the method 400 can comprise a number of steps 401- 411. However, it should be noted that certain of the described steps 401-411 can be performed in a chronological order that differs from that indicated by the numer- ical order, and that certain of them can be performed in parallel with one another, according to various embodiments. Certain of the described steps 401-411 are performed only in certain alternative embodiments, such as steps 406-411. The method 400 comprises the following steps: Step 401
