Abstract

Current implementations of Bluetooth (BT) headsets do not provide any indication to the user when the signal strength goes low on a mobile phone or mobile device. Since the user is not going to watch the phone screen while using the BT headset, he/she would not be aware of the fact that the coverage is going low until the call is lost.

SIGNAL STRENGTH INDICATORS IN BLUETOOTH HEADSETS

Mechanism to Alert Users of Bluetooth Headsets When the Signal Strength Weakens

Disclosed Anonymously

Current implementations of Bluetooth (BT) headsets do not provide any indication to the user when the signal strength goes low on a mobile phone or mobile device.  Since the user is not going to watch the phone screen while using the BT headset, he/she would not be aware of the fact that the coverage is going low until the call is lost.

There is an AT command in the in the Bluetooth specification, +CIEV, which specifies the values of the indicators (such as Service, Call, Call setup,

Battery

charge, Signal, etc.) that applies to the current session.  Unfortunately, none of the headsets seem to use the Signal indicator.  Car kits use this indicator to display the appropriate number of “bars” on their UI.

It would be beneficial to the end user, if the Signal indicator is incorporated within the headset, whereby, whenever the signal strength on phone goes below a certain range, an appropriate beep is produced on the headset speaker.  Note that the signal strength indicator is normally specified within the rage of 0 to 5.  The following scheme could be adopted to provide the appropriate feedback to the user:

5 – no alerts

4 – no alerts

3 – single beep every minute

2 – three beeps every 10 seconds

1 – constant beep
