## Background
FIELD OF INVENTION
The present invention relates to the field of short distance wireless communications, more specifically to a Bluetooth Communication System and an associated method for switching modes of operation between electronic devices, such as switching NFC enabled speaker between multiple NFC enabled mobile phones.
BACKGROUND OF THE INVENTION
Bluetooth communication system generally provides a communication channel between two electronic devices via a short-range radio link. The Bluetooth radio link is intended to be a cable replacement between two or more mobile and/or fixed electronic devices. The mobile or fixed electronic devices include mobile phones, audio headsets, laptop computers, speakers, and the like with different or same operating systems.
The Bluetooth communication system is a low-cost, low-power and short-distance wireless communication technology extensively used in all kinds of mobile and/or fixed electronic devices used in day to day life. The built-in Bluetooth chip of these devices not only can perform two-way wireless transmissions, but also can provide user-friendly functions. The Bluetooth signal transfer facility of these devices provides the technological advantages of hands-free functions.
Bluetooth communication system can be either point-to-point or point-to-multipoint to provide connection links among multiple electronic devices. When one Bluetooth device communicates with another Bluetooth device, one will generally be a sending device and the other would be a recipient device. There always exists a need to identify the recipient device or pair up a desired recipient device with the sending device. This is necessary because, without such proper and desired paring, there is possible that the sending device may be accidentally connected to a wrong recipient device producing wrong outcomes.
In the light of aforementioned discussion, there exists a need for a Bluetooth communication system and an associated method thereof for switching modes of operation between electronic devices using a user operable interface system.

The example and embodiment is provided by way of explanation of the invention, and is not meant as a limitation of the invention. For example, features illustrated or described as part of one embodiment may be used with another embodiment to yield still a further embodiment.
Turning now to accompanying drawings FIG. 1-FIG. 4, FIG. 1, in particular which shows a Bluetooth communication system 100 in accordance with the present invention. As shown, the system 100 includes a first Bluetooth enabled electronic device 102 having incorporated a Bluetooth chip 104 and an associated processing circuitry 106, and a user operable interface 108 associated therewith to enable a user to selectively pair up and switch the first Bluetooth enabled electronic device 102 among one or more second Bluetooth enabled electronic devices 110a, 110b, and 110c, as shown. The user operable interface 108 configuration helps switching the processing circuitry 106 to a desired second Bluetooth enabled electronic devices 110a, 110b, and 110c, and switch operational mode of the desired second Bluetooth enabled electronic devices 110a, 110b, and 110c from a first mode of operation to a second mode of operation or vice versa to establish a Bluetooth communication link. The user operable interface 108 switches and associates the first Bluetooth enabled electronic device 102 with an unused second Bluetooth enabled electronic devices 110a, 110b, and 110c to establish a Bluetooth communication link therewith and continue the communication till the user operable interface 108 is switched again by the user.
The functional aspect of the present invention will be explained in detail with respect to FIG. 2 and FIG. 3 where there is shown the first Bluetooth enabled electronic device i.e. a speaker (for example) 102 capable of establishing Bluetooth communication simultaneously with plurality of Bluetooth enabled electronic devices i.e. three NFC enabled mobile phones (for example) 110a, 110b, and 110c and is also capable of enabling the user to switch the operating speaker 102 between the mobile phones 110a, 110b, and 110c. 
FIG. 2-FIG. 3 as shown illustrates one example of the user operable interface switching according to the present invention. As shown, the NFC enabled speaker 102 establishes a Bluetooth connection with the mobile phones 110a, 110b, and 110c simultaneously to communicate and switch the speakers' 102 operation between them. The switching is implemented by actuation of the user operable interface 108 incorporated preferably in the speaker 102. The user operable interface 108 can be in the form of manual switch, a remote form, or the like. When actuated, the user operable interface 108 switches the processing circuitry 106 to connect to one of the mobile phones 110a, 110b, and 110c, and switch the operational mode of the mobile phone 110a, or 110b, or 110c in connection from one mode of operation i.e. active transmission mode to an another operational mode i.e. inactive transmission mode or vice versa.
As best described in FIG. 3 with an example to show how the user operable interface 108 helps in switching the operations of the speaker 102 between the mobile phones 110a, 110b, and 110c. According to the embodiment, the speaker 102 on detecting the proximity of the mobile phones 110a, 110b, and 110c establishes the Bluetooth connectivity therewith, and the speaker 102 communicates with a particular mobile phone 1 to play audio being played in the mobile phone 1. The user when selectively switches the speaker to mobile phone 2, a signal is sent to the mobile phone 1 to pause the audio being played thereon, and simultaneously a play signal to the mobile phone 2 to play the audio being played by the mobile phone 2. Similarly, when the user selectively switches the speaker to mobile phone 3, a signal is sent to the mobile phone 2 to pause the audio being played thereon, and simultaneously a play signal to the mobile phone 3 to play the audio being played by the mobile phone 3. Further, when the user selectively switches the speaker to mobile phone 1 again, a signal is sent to the mobile phone 3 to pause the audio being played thereon, and simultaneously a play signal to the mobile phone 1 to play the audio being played by the mobile phone 1.
Referring to FIG. 4 is an example method of a Bluetooth communication according to the present invention. The method 400 starts at step 41 which describes switching a processing circuitry 106 of a Bluetooth enabled electronic device 102 among plurality of Bluetooth enabled electronic devices 110a, 110b, and 110c. The user operable interface 108 of the Bluetooth enabled electronic device 102 switches the processing circuitry 106 among plurality of Bluetooth enabled electronic devices 110a, 110b, and 110c. The user operable interface 108 preferably includes a manual switch, a switch in the remote form, and the like.
Next the step 42 describes switching operational modes of Bluetooth enabled electronic devices 110a, 110b, and 110c between a first mode of operation (an active transmission mode or play mode) to a second mode of operation (an inactive transmission mode or pause mode) or vice versa. By the way of an example, plurality of mobile phones phone 1, phone 2, and phone 3 can be switched between their operational modes of operation when they are in Bluetooth communication with a speaker configured to play audio being played by the mobile phones, as best explained in conjunction with FIG. 3 above. Further the step 43 describes establishment of a Bluetooth communication link in between the Bluetooth enabled electronic devices mobile phones, and the like.
Although embodiments of the system is explained considering specific electronic devices like speaker and phones and specifically use of Bluetooth communication, it is to be understood that the subject of the appended claims is not necessarily limited to the specific types of electronic devices and only to Bluetooth communication. For example, one or more other mobile communication devices or consumer devices and other short range wireless communication like Wi-Fi, Wireless Local Area Network (WLAN), Infrared Data Association (IrDA), Zigbee, Radio Frequency Identification (RFID), and Near Field Communication (NFC), and the like can be used instead of the specific electronic devices and Bluetooth communication described above and still achieve desirable results. Moreover, the specific systems and methods are disclosed as example implementations of Bluetooth and short range wireless communication technology.
