Call setup in wireless communication devices

A wireless communication device, comprising:

• a Radio Frequency (RF) resource;
• a memory;
• and
• a processor configured to:
• receive a call setup page from a network while in a connected mode;
• transmit a Scheduling Request (SR) probe to the network in response to determining that a data inactivity duration exceeds a threshold upon receiving the call setup page, wherein a value of the threshold is based on whether the wireless communication device is a multi-Subscriber Identity Module (SIM) wireless communication device, a Concurrent Radio Access Technology (CRAT) wireless communication device, or a single-SIM wireless communication device;
• and
• set the call setup page as FALSE in response to determining that the data inactivity duration does not exceed the threshold;
• and
• perform a local connection release in response to determining that an uplink grant corresponding to the SR probe has not been received.

A wireless communication device, comprising:

• means for receiving a call setup page from a network while in a connected mode;
• means for transmitting a Scheduling Request (SR) probe to the network in response to determining that a data inactivity duration exceeds a threshold upon receiving the call setup page, wherein a value of the threshold is based on whether the wireless communication device is a multi-Subscriber Identity Module (SIM) wireless communication device, a Concurrent Radio Access Technology (CRAT) wireless communication device, or a single-SIM wireless communication device;
• and
• means for setting the call setup page as FALSE in response to determining that the data inactivity duration does not exceed the threshold;
• and
• means for performing a local connection release in response to determining that an uplink grant corresponding to the SR probe has not been received.

A non-transitory computer-readable medium containing processor-readable instructions such that, when executed, causes a processor of a wireless communication device to:

• receive, by the wireless communication device, a call setup page from a network while in a connected mode;
• determine whether a data inactivity duration exceeds a threshold upon receiving the call setup page, wherein a value of the threshold is based on whether the wireless communication device is a multi-Subscriber Identity Module (SIM) wireless communication device, a Concurrent Radio Access Technology (CRAT) wireless communication device, or a single-SIM wireless communication device;
• set the call setup page as FALSE in response to determining that the data inactivity duration does not exceed the threshold;
• transmit a Scheduling Request (SR) probe to the network in response to
• determining that the data inactivity duration exceeds the threshold;
• determine whether an uplink grant corresponding to the SR probe has been received;
• and
• perform a local connection release in response to determining that the uplink grant corresponding to the SR probe has not been received.
