APPARATUSES AND METHODS FOR COORDINATING OPERATIONS BETWEEN CIRCUIT SWITCHED (CS) AND PACKET SWITCHED (PS) SERVICES WITH DIFFERENT SUBSCRIBER IDENTITY CARDS, AND MACHINE-READABLE STORAGE MEDIUM

摘要

A wireless communications device includes a radio frequency (RF) module and a baseband chip. The baseband chip is configured to initiate a mobile originated (MO) call through the RF module with a first subscriber identity card when the RF module is occupied by performing a packet switched (PS) data service with a second subscriber identity card, arbitrate a first protocol stack handler to suspend or terminate the 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 PS data service associated with the second subscriber identity card is suspended or terminated.

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 with a first subscriber identity card when the RF module is occupied by performing a packet switched (PS) data service with a second subscriber identity card, arbitrate a first protocol stack handler to suspend or terminate the 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 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 PS data service and the arbitration of the first protocol stack handler to suspend or terminate the PS data service is performed when the MO call has a higher priority than the PS data service.
