Call handling across subscriptions in dual SIM dual active (DSDA) devices via short range wireless
First Claim
1. A method operational on a multi-subscriber identity module audio gateway device, comprising:
- establishing a wireless connection between the audio gateway device and a hands free device using a protocol supporting a single subscription;
establishing a first call which terminates or originates at the hands free device via a first subscription;
setting up an outgoing call via a second subscription by;
receiving a first indicator from the hands free device to switch subscriptions, where the first indicator does not specify a subscription;
establishing an originating second call via the second subscription which originates at the hands free device; and
setting up an incoming call via the second subscription by;
sending a second indicator to the hands free device of an incoming third call, where the second indicator does not specify a subscription; and
establishing the third call via the second subscription which terminates at the hands free device.

Abstract
An audio gateway device may establish a wireless connection between the audio gateway device and the hands free device using a protocol supporting a single subscription. The audio gateway device may also establish a first call which terminates or originates at the hands free device via a first subscription. An outgoing call may be established via a second subscription by: (a) receiving a first indicator from the hands free device to switch subscriptions, where the first indicator does not specify a subscription; and (b) establishing an originating second call via the second subscription which originates at the hands free device. Similarly, an incoming call may be established via the second subscription by: (a) sending a second indicator to the hands free device of an incoming third call, where the second indicator does not specify a subscription; and (b) establishing the third call via the second subscription which terminates at the hands free device.

23. A hands free device, comprising:
-
a first wireless communication interface to communicate with an audio gateway device; a processing circuit coupled to the first wireless communication interface and configured to establish a wireless connection between the hands free device and the audio gateway device using a protocol supporting a single subscription; establish a first call which terminates or originates at the hands free device via a first subscription; setup an outgoing call via a second subscription by; sending a first indicator to the audio gateway device to switch subscriptions, where the first indicator does not specify a subscription; establishing an originating second call via the second subscription which originates at the hands free device; setup an incoming call via the second subscription by; receiving a second indicator at the hands free device of an incoming third call, where the second indicator does not specify a subscription; and establishing the third call via the second subscription which terminates at the hands free device. - View Dependent Claims (24, 25, 26, 27)
