System and Methods for Cancelling Uplink Traffic Channel Bursts to Improve Performance in a Multi-SIM Wireless Communication Device

摘要

Methods and devices are disclosed for enabling improved performance on a single-transmit multi-SIM wireless communication device. The wireless communication device may detect a voice communication on a modem stack associated with the first SIM and a data communication on a modem stack associated with the second SIM. The wireless communication device may identify a data rate used by the voice codec to encode uplink traffic channel (TCH) bursts in the voice communication, and determine whether the identified data rate used by the voice codec permits TCH burst cancellation. If it is determined that the identified data rate used by the voice codec permits TCH burst cancellation, the wireless communication device may downgrade a portion of the uplink TCH bursts scheduled on the modem stack associated with the first SIM.

主权项

1. A method of improving performance of a multi-subscriber identification module (multi-SIM) wireless communication device having at least a first SIM associated with a first radio frequency (RF) receive resource and a second SIM associated with a second RF receive resource, the method comprising:
detecting a voice communication on a modem stack associated with the first SIM and a data communication on a modem stack associated with the second SIM; identifying a data rate used by a voice codec to encode uplink traffic channel (TCH) bursts in the voice communication; determining whether the identified data rate used by the voice codec permits TCH burst cancellation; and downgrading a portion of the uplink TCH bursts scheduled on the modem stack associated with the first SIM in response to determining that the identified data rate used by the voice codec permits TCH burst cancellation.
