1. A wireless communications device, comprising:
- a Radio Frequency (RF) module; and
a Baseband chip configured to initiate a mobile originated (MO) call through the RF module from the wireless communications device with a first subscriber identity card when the RF module is occupied by performing a background packet switched (PS) data service with a second subscriber identity card, arbitrate a first protocol stack handler to suspend or terminate the background PS data service associated with the second subscriber identity card in response to initiating the MO call associated with the first subscriber identity card, and arbitrate a second protocol stack handler to make the MO call associated with the first subscriber identity card when the background PS data service associated with the second subscriber identity card is suspended or terminated,wherein the Baseband chip further determines whether the MO call has a higher priority than the background PS data service, prior to arbitrating the first protocol stack handler to suspend or terminate the background PS data service, and the arbitration of the first protocol stack handler to suspend or terminate the background PS data service is performed when the MO call has a higher priority than the PS data service; and
wherein the Baseband chip further arbitrates the second protocol stack handler to regain service for the first subscriber identity card subsequent to the arbitrating the first protocol stack handler to suspend or terminate the background PS data service and prior to arbitrating the second protocol stack handler to make the MO call.

Abstract
A wireless communications device is provided with a Baseband chip capable of coordinating operations between circuit switched (CS) and packet switched (PS) services with different subscriber identity cards. The Baseband chip is configured to receive a request for making a mobile originated (MO) call with a first subscriber identity card when performing a background PS data service with a second subscriber identity card. The Baseband chip suspends or terminates the background PS data service in response to the request, and further makes the MO call with the first subscriber identity card when the background PS data service is suspended or terminated.

12. A method for coordinating operations between circuit switched (CS) and packet switched (PS) services with different subscriber identity cards in a wireless communications device, comprising:
-
initiating a Mobile Originated (MO) call through a RF module from the wireless communications device with a first subscriber identity card when the RF module is occupied by performing a background PS data service with a second subscriber identity card; arbitrating a first protocol stack handler to suspend or terminate the background PS data service associated with the second subscriber identity card in response to initiating the MO call associated with the first subscriber identity card; and arbitrating a second protocol stack handler to make the MO call associated with the first subscriber identity card when the background PS data service associated with the second subscriber identity card is suspended or terminated; wherein the Baseband chip further determines whether the MO call has a higher priority than the background PS data service, prior to arbitrating the first protocol stack handler to suspend or terminate the background PS data service, and the arbitration of the first protocol stack handler to suspend or terminate the background PS data service is performed when the MO call has a higher priority than the PS data service; and wherein the Baseband chip further arbitrates the second protocol stack handler to regain service for the first subscriber identity card subsequent to the arbitrating the first protocol stack handler to suspend or terminate the background PS data service and prior to arbitrating the second protocol stack handler to make the MO call. - View Dependent Claims (13, 14, 15, 16)

17. A non-transitory machine-readable storage medium comprising program code, which, when executed, causes a wireless communications device to perform a method for coordinating operations between circuit switched (CS) and packet switched (PS) services with different subscriber identity cards in a wireless communications device, the method comprising:
-
initiating a Mobile Originated (MO) call through a RF module from the wireless communications device with a first subscriber identity card when the RF module is occupied by performing a background PS data service with a second subscriber identity card; arbitrating a first protocol stack handler to suspend or terminate the background PS data service associated with the second subscriber identity card in response to initiating the MO call associated with the first subscriber identity card; and arbitrating a second protocol stack handler to make the MO call associated with the first subscriber identity card when the background PS data service associated with the second subscriber identity card is suspended or terminated; wherein the Baseband chip further determines whether the MO call has a higher priority than the background PS data service, prior to arbitrating the first protocol stack handler to suspend or terminate the background PS data service, and the arbitration of the first protocol stack handler to suspend or terminate the background PS data service is performed when the MO call has a higher priority than the PS data service; and wherein the Baseband chip further arbitrates the second protocol stack handler to regain service for the first subscriber identity card subsequent to the arbitrating the first protocol stack handler to suspend or terminate the background PS data service and prior to arbitrating the second protocol stack handler to make the MO call.

18. A wireless communications device, comprising:
-
a Radio Frequency (RF) module; and a Baseband chip configured to initiate a mobile originated (MO) call through the RF module from the wireless communications device with a first subscriber identity card when the RF module is occupied by performing a background packet switched (PS) data service with a second subscriber identity card, redirect the MO call to the second subscriber identity card, and make the MO call with the second subscriber identity card; wherein the Baseband chip further determines whether the MO call has a higher priority than a background PS data service, prior to arbitrating a first protocol stack handler to suspend or terminate the background PS data service, and the arbitration of the first protocol stack handler to suspend or terminate the background PS data service is performed when the MO call has a higher priority than a PS data service; and wherein the Baseband chip further arbitrates a second protocol stack handler to regain service for the first subscriber identity card subsequent to the arbitrating the first protocol stack handler to suspend or terminate the background PS data service and prior to arbitrating the second protocol stack handler to make the MO call. - View Dependent Claims (19, 20)
