System and Methods for improving Page Decode Performance During Reading of System Information on a Multi-SIM Wireless Communication Device

摘要

Methods and devices are disclosed for enabling improved performance for page decodes on a SIM of a multi-SIM wireless communication device in which a shared radio frequency (RF) resource is used to read system information for a different SIM. After determining that a first SIM is using the shared RF resource to decode SIBs, the wireless device may receive information about an upcoming page decode time for monitoring a paging channel associated with the second SIM. The wireless device may obtain system information block (SIB) scheduling information associated with the first SIM, and may create a RF resource release gap during the system information read period based on the SIB scheduling information and the upcoming page decode time. Control of the RF resource may be released from the modem stack associated within the first SIM, and gained by a modem stack associated with the second SIM during the RF resource release gap.

主权项

1. A method of improving performance of a multi-subscriber identification module (SIM) wireless communication device having at least a first SIM and second SIM associated with a shared radio frequency (RF) resource, wherein the first SIM is connected to a first network that broadcasts system information blocks (SIBs), the method comprising:
receiving information about an upcoming page decode time for monitoring a paging channel associated with the second SIM, wherein the upcoming page decode time overlaps with a system information read period for the first SIM; retrieving system information block (SIB) scheduling information associated with the first SIM; creating a RF resource release gap during the system information read period based on the SIB scheduling information and the upcoming page decode time, wherein control of the RF resource is released by a modem stack associated with the first SIM; and providing control of the RF resource to a modem stack associated with the second SIM during the RF resource release gap.
