PROBLEM TO BE SOLVED: To perform data communications by dual sim dual active (DSDA) user equipment (UE), while simultaneously conducting two concurrent voice calls.SOLUTION: The UE receives a request to perform data communications while conducting a first voice call on a first radio and concurrently conducting a second voice call on a second radio. The UE then determines whether one of the voice calls is currently on hold. The UE performs the data communications using the radio on which the held call is being conducted. The UE therefore dynamically selects available slots from the first radio and the second radio for performing the data communication, on the basis of which of the first radio and the second radio has a voice call that is currently on hold. The data communications are performed using a Long Term Evolution (LTE) protocol stack. |
