Abstract
Systems and methods enable a user of a dual-SIM dual active (DSDA) wireless device to handle multiple simultaneous independent real time calls SIMs to prevent calls from being dropped on a multi-SIM wireless device. In the various embodiments, a DSDA device user on an active call may receive another incoming voice call and select to process the incoming voice call using a voice/text conversation mode. In the various embodiments, the parties on the multiple simultaneous calls may not be aware of the wireless device's simultaneous communications with one another that the wireless device user is communicating with another party simultaneously with the wireless device

A method of maintaining simultaneous active calls on a multi-SIM wireless device, comprising:
- receiving an incoming voice call on a first radio frequency (RF) resource associated with a first SIM;
- determining whether the wireless device has an active voice call on a second RF resource associated with a second SIM;
- and
- entering a voice/text conversation mode in response to determining that the wireless device has an active voice call on the second RF resource associated with the second SIM,
- wherein the voice/text conversation mode comprises:
- converting a caller's speech into text data;
- displaying the text data on the wireless device;
- receiving text inputs from a user;
- converting the text inputs into machine-generated speech;
- and
- transmitting the machine-generated speech to the caller.
A multi-SIM wireless device, comprising:
- a first SIM;
- a second SIM;
- a display
- a memory;
- a first radio frequency (RF) resource associated with the first SIM;
- a second RF resource associated with the second SIM;
- and
- a processor coupled to the first and second SIMs, the display, the memory, the first and second RF resources, wherein the processor is configured with processor-executable instructions to perform operations comprising:
- receiving an incoming voice call on the first RF resource associated with the first SIM;
- determining whether the wireless device has an active voice call on the second RF resource associated with the second SIM;
- and
- entering a voice/text conversation mode in response to determining that the wireless device has an active voice call on the second RF resource associated with the second SIM,
- wherein the voice/text conversation mode comprises:
- converting a caller's speech into text data using a speech-to-text (STT) conversion engine;
- displaying the text data on the wireless device;
- receiving text inputs from a user;
- converting the text inputs into machine-generated speech using a text-to-speech (TTS) conversion engine;
- and
- transmitting the machine-generated speech to the caller.
A multi-SIM wireless device, comprising:
- means for receiving an incoming voice call on a first radio frequency (RF) resource associated with a first SIM;
- means for determining whether the wireless device has an active voice call on a second RF resource associated with a second SIM;
- means for entering a voice/text conversation mode in response to determining that the wireless device has an active voice call on the second RF resource associated with the second SIM,
- means for converting a caller's speech into text data;
- means for displaying the text data on the wireless device;
- means for receiving text inputs from a user;
- means for converting the text inputs into machine-generated speech;
- and
- means for transmitting the machine-generated speech to the caller.
A non-transitory processor-readable storage medium having stored thereon processor-executable instructions configured to cause a multi-SIM wireless device processor to perform operations comprising:
- receiving an incoming voice call on a first radio frequency (RF) resource associated with a first SIM;
- determining whether the wireless device has an active voice call on a second RF resource associated with a second SIM;
- and
- entering a voice/text conversation mode in response to determining that the wireless device has an active voice call on the second RF resource associated with the second SIM,
- wherein the voice/text conversation mode comprises:
- converting a caller's speech into text data;
- displaying the text data on the wireless device;
- receiving text inputs from a user;
- converting the text inputs into machine-generated speech;
- and
- transmitting the machine-generated speech to the caller.
