BACKGROUND ART
Today there are many different ways of communicating via modern technology, such as PSTN telephony, IP telephony and mobile telephony, SMS, instant messaging (chat), video conferencing, voice-mail, presence information etc. It is common for people to have both a mobile phone, and a desk phone/soft phone. A mobile phone is very practical when the user is away from his desk, but when he is working at his desk he may in many cases prefer to use a desktop phone or a soft phone. He may also prefer to use a headset, as this allows him to simultaneously operate his computer, write on a paper, looking in drawers with both hands etc. It may also be desirable that the user's presence status on computer or telecommunications network is updated, when the user arrives at his desk. Presence status is real time information about a person's ability and willingness to communicate. Other persons on the same network or connected to the same presence service provider can be updated in real time with presence status of his contacts. All this relates to what is termed “unified communications”. An example of a unified communications system is Microsoft Lync.
A headset base unit is a unit, which is arranged between a headset and one or more telecommunication devices, such as a PSTN (Public Switched Telephone Network) desk phone, and IP (Internet Protocol) desk phone, an IP soft phone (installed on a computer) and a mobile phone. The headset base unit normally comprises a headset holder for holding the headset when not in use. The headset comprises one or two earphones and a microphone. The headset base unit is typically placed on a desk beside a telephone and/or a PC. When the user wants to use the headset, he picks up the headset and arranges on his ear or head. The headset can be connected to the headset base unit by a wire or wirelessly. In both cases, the user's hands are free for other purposes such as using the computer or handling papers while communicating via the headset.
A mobile communication device is a broad group of devices comprising mobile phones, PDAs (personal digital assistants), media players, tablet computers etc.

MODES FOR CARRYING OUT THE DISCLOSURE
It should be noted that the drawings are schematic and only elements most essential for the explanation of the disclosure are disclosed here. Many details, which are well known and easy to implement for a skilled person are left out for clarity reasons. The same reference signs are, in several instances, used for the same or corresponding parts.
FIGS. 1 and 2 disclose a headset system 14 comprising a base unit 1 according to a first embodiment of the disclosure and a headset 4. The headset base unit 1 comprises a base housing 2, a headset holder 3, a device holder 10 and a device connector 20. The headset holder 3 is shaped as a post for receiving the headset 4. In FIGS. 1 and 2, the headset 4 is received by the headset holder 4. The headset 4 comprises a circular earphone 40, a microphone arm 30, a headband 28 and an end piece 29. It is not visible on the drawing but a charging terminal on the holder 3 is an electrical contact with a corresponding charging terminal on the earphone 40, when the headset 4 is held by the headset holder 3. The base housing 2 comprises a device holder 10 for holding a mobile communication device, such as a smart phone 11. The device holder 10 is provided as a recess in the top surface of the base housing 2 and a connector 20 is provided in the recess 10. In FIG. 2, a smartphone 11 is arranged in the recess 10 such that the connector 20 is engaged with a corresponding connector on the smart phone 11. In this embodiment, the connector 20 is a Micro-B USB connector. However, other types of connectors could be used.
The smart phone 11 comprises a touch screen display 12, which is easy to watch and touch due to the inclined position of the smart phone 11. The touch screen display 12 is, off course, works as a user interface for controlling the functions of the smart phone. However, the touch screen display 12 of the smart phone 11 may according to the disclosure also be utilized for controlling functions not directly related to the smart phone 11, which will be explained further in the following.
FIG. 3 discloses a communication system 46, where the headset base unit 1 according to the first embodiment is connected to a desk phone 6 by means of a cable 31 and to a laptop computer 7 by means of a cable 32. The desk phone 33 is by means of a connection 33 connected to an external communications network 35. In addition, the laptop 7 is by means of a connection 34 connected to the external communications network 35. The external communications network 35 is a world-wide network comprising the public switched telephone network (PSTN), which is the network of the world's public circuit-switched telephone networks including fixed as well as mobile phones, and the Internet, which is the network of the world's public IP-based packet-switched networks. The smart phone 11 is also connected to the external communications network 35 by means of a GSM link 14.
A so-called “app” (application) is installed on the smart phone 11 in order to expand it with added functionally to cover functions not directly related to the smart phone. Thus, the added functionality comprises call management relating to calls on the desk phone 6 and soft phone calls on the laptop computer 7. The headset base unit 1 itself is adapted to handle calls on the desk phone 6 and the laptop computer 7, but the user may manage these calls by means of the touch-screen display 12 of the smartphone 11. The app can be configured to provide direct access between the smart phone screen and keyboard and the base 2 via connector 20 so that keystrokes on the smartphone, when engaged with the connector act as if they are a dedicated keyboard for the base. This can be done by running an appropriate software script on the smartphone to redirect keystrokes and screen display, with additional software to interpret outputs from the phone to the connect which may optionally be in the base or headset. Alternatively, the smart phone may run an app which links to the base or headset via the internet or a local area network (LAN) , Bluetooth®, Zigbee® or similar short range wireless network, which the base/headset is also already joined to.
Another embodiment which is also shown in FIG. 2, has a cradle recess/device holder 10 with a “dumb” keyboard display unit 11 which is not a smart phone but of a type known in the GN 9470 product, except removable via connector 20. The dumb unit 11 may be replaced by a smart phone, which is sized to be received in the holder. Thus, in this embodiment, the user may use the dumb screen/keyboard in place of the smart phone when the smart phone is unavailable by merely swapping it out. The software in the base or headset will detect which device is present.
A further embodiment is shown in FIG. 8 where the base has two holders 10 and 10a to accommodate multiple devices (smart phone/dumb screens) or where, the dumb screen 12a is permanently affixed to the base and a holder 10a can receive another device such as a smart phone. When a smart phone is placed in holder 10a, it notifies the base and headset to supersede the control of screen 12a. If two smart devices are plugged into holders 10/10a, the system will preferably determine that the front most has control and the rearmost will merely be providing power for charging.
When the user sits at his desk with the desk phone 6, the laptop 7 and the headset system 14 with his smart phone 11 docked in the headset base unit 1, he may use the headset 4 for telephone calls via the desk phone 6, the laptop 7 and the smart phone 11. He may as an example manage calls in the following ways: the headset base unit 1 detects, that the smart phone 11 is docked, and the communication software on the laptop is informed that the user is “present” at the desk. This may be achieved by many means. Thus, the softphone on the laptop may be set to be automatically selected for outgoing calls. If the user enters a phone number by means of the touch-screen display, the outgoing call is executed as an Internet Protocol call by the soft phone on the laptop 7. The user will communicate via the wireless headset 4 and may not care about, whether the call is a desk phone call, a soft phone call or a mobile phone call. If there is an incoming call on any of the desk phone 6, the laptop 7 and the smart phone 11, the user may put on the headset 4 and accept the call by touching an “accept call” soft button on the touch-screen display 12. If the user is having a call on his smart phone 11 using the headset 4 and wants to leave the office, he may dock the headset 4 on the headset holder 3, pick up the smartphone 11 from the device holder 10 and continue the call while leaving the office. If the user is in a call on either the desk phone 6 or the laptop 7 and wants to leave the office, he may touch a soft button on the display 12 for transferring the call to his smart phone 11, before he is docking the headset 4 and picking up the smart phone 11. When he takes the smart phone 11 out of the device holder 10, the communications software on the laptop 7 is informed that the user is “not present” and all incoming calls to the soft phone may be set to be transferred to the smart phone.
FIG. 4 discloses a diagram of the headset system 14. As earlier mentioned, the headset base unit 1 comprises a base housing 2, a headset holder 3, a device holder 10 with a device connector 20. The headset base unit 1 also comprises a processor 9, a first connection device 5, a second connection device 8, a headset holder terminal 21 and a third connection device 13 comprising the device connector 20. The headset holder terminal 21 is in electrical contact with a headset terminal 23, whereby a rechargeable headset battery 49 can be charged when the headset 4 is docked. The second connection device 8 comprises a DECT (Digital Enhanced Cordless Telecommunications) transceiver 15 and a DECT antenna 41 for wireless communication with the headset 4. The headset base unit 1 and the headset 4 may be provided with transceivers and antennas according to the Bluetooth® or other radio standards instead of the DECT standard. The headset base unit 1 is connected to the desk phone 9 by means of a 4 wire phone cable 31 and to the laptop 10 by means of a USB cable 32.
The headset 4 comprises besides the already mentioned headset terminal 23 and headset battery 49, a headset processor 22, a speaker 24, a microphone 24, a DECT transceiver 16 and a DECT antenna 42. The mechanical parts, such as the headband 4 and the microphone arm 30 are not shown.
FIG. 5 disclose a diagram of a headset system 14 according to a second embodiment of the disclosure. In this embodiment, the device holder is simply a flat surface 10 on which the smart phone 11 can be placed. Furthermore, the headset base unit 1 and the smart phone 11 are not electrical connected when the smart phone 11 is docked. Instead, the headset base unit 1 is provided with an inductive charging transmitter circuit 36 and the smart phone 11 is provided with a corresponding inductive charging receiver circuit 37. Furthermore, the headset base unit 1 and the smart phone 11 are provided with Bluetooth® antennas 43, 44 and Bluetooth® transceivers 17, 18 for wireless communication via a Bluetooth® link 39. A base sensor 27 detects docking of the smart phone 11 and activates charging and Bluetooth® communication. Otherwise, the headset base unit 1 may work in the same manner as the first embodiment.
A variation on the above embodiment involves the construction of FIG. 8 where there are two holders 10/10a, though in the preferred embodiment, holder 10a is immediately adjacent holder 10. In such case screen 12a also includes inductive charging circuits and the placement of a smart phone in holder 10a provides sufficient proximity to charge such smart phone no charging connector is needed in the holder. If the smart phone is wirelessly connected to the base/headset, such as by Bluetooth®, then no connector is needed in the holder. This is advantageous, as smart phone manufacturers tend to change connector configurations.
It is noted that the inductive charging circuit can be used also a detector for the presence of a smart phone as it will increase current draw when in proximity.
FIG. 6 discloses a front view of the smart phone 11 when held by a headset base unit 1 and when the app for call management is activated. The touch screen display 12 discloses a smart phone icon 47, a desk phone icon 18 and a laptop icon 19. An incoming call icon 48 flashes and indicates that there is an incoming call on the desk phone 6. The user may accept the call by simply undocking the headset 4 or if it is already undocked touching the desk phone icon 18 on the touch screen display 12 of the smart phone 11. The touch screen display 12 may also show a list of contacts, call lists etc. Furthermore, contact lists may be synchronized with the desk phone 6 and the laptop 7 when the smart phone 11 is docked.
FIG. 7 discloses a flow diagram showing a basic use of a headset base unit according to the disclosure. The user may arrive at his desk and dock his smart phone in the device holder of the headset base unit. The headset and/or the smartphone sense this, where after the smart phone is instructed to enter control mode and start the installed app. Now, the user is able to manage calls on the desk phone and laptop by means of the touch screen display of the smart phone.
The invention is not limited to the embodiments shown above. Thus, the use of a smart phone may be replaced by the use of a more traditional mobile phone with a numerical key pad, a tablet computer, such as an iPad® or Samsung Galaxy Tab 10.1®, a personal PDA (personal digital assistant), a media player etc.
The headset and the headset base unit may communicate wirelessly according to the Bluetooth®, DECT or Wi-Fi standards or even other radio standards. Also, the headset may be a corded headset which is connected by a wire to the headset base unit.
The disclosure also includes a method of configuring the apparatus above. In particular, the method includes connecting multiple sources of telecommunication feeds from a plurality of communications devices, to a wireless headset controlled by a smart phone device via a base unit having a holder for the smart device having a keyboard and screen comprising:
