System and Methods for Avoiding Call Performance Degradation in a Wireless Communication Device

A wireless communication device, comprising:

• a radio frequency (RF) resource;
• and
• a processor coupled to the RF resource, configured to connect to at least a first subscriber identity module (SIM), and configured with processor-executable instructions to:
• detect an active communication with a first network on a modem stack associated with the first SIM;
• detect when a control signal is received on the modem stack associated with the first SIM;
• identify a percentage of scheduled uplink feedback corresponding to the control signal received on the modem stack associated with the first SIM that will be transmitted on the first network (“identified percentage”);
• determine whether the identified percentage is less than a threshold;
• and
• ignore operations instructed by the control signal received on the modem stack associated with the first SIM in response to determining that the percentage of scheduled uplink feedback that will be transmitted on the first network is less than the threshold.

A wireless communication device, comprising:

• a radio frequency (RF) resource;
• means for detecting an active communication with a first network on a modem stack associated with a first subscriber identity module (SIM);
• means for detecting when a control signal is received on the modem stack associated with the first SIM;
• means for identifying a percentage of scheduled uplink feedback corresponding to the control signal received on the modem stack associated with the first SIM that will be transmitted on the first network (“identified percentage”);
• means for determining whether the identified percentage is less than a threshold;
• and
• means for ignoring operations instructed by the control signal received on the modem stack associated with the first SIM in response to determining that the percentage of scheduled uplink feedback that will be transmitted on the first network is less than the threshold.

A non-transitory processor-readable storage medium having stored thereon processor-executable instructions configured to cause a processor of a wireless communication device having a radio frequency (RF) resource configured to connect to at least a first subscriber identity module (SIM) to perform operations comprising:

• detecting an active communication with a first network on a modem stack associated with the first SIM;
• detecting that a control signal was received on the modem stack associated with the first SIM;
• identifying a percentage of scheduled uplink feedback corresponding to the control signal received on the modem stack associated with the first SIM that will be transmitted on the first network (“identified percentage”);
• determining whether the identified percentage is less than a threshold;
• and
• ignoring operations instructed by the control signal received on the modem stack associated with the first SIM in response to determining that the percentage of scheduled uplink feedback that will be transmitted on the first network is less than the threshold.
