Abstract: 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.

Abstract: The present disclosure presents a method and apparatus for expedited mobile device handover that include performing one or more handover tasks in parallel that have previously been performed exclusively in serial. For example, the disclosure presents a method for wireless device handover, which may include acquiring a target cell, ascertaining a system frame number (SFN) of the target cell, calculating a connection frame number (CFN) for a dedicated channel (DCH) transmission, and reconfiguring a dedicated physical channel (DPCH) based on the calculated CFN. In addition, such an example method may include, while performing at least one of the ascertaining of the SFN, the calculating of the CFN, and the reconfiguring of the DPCH, contemporaneously performing at least one of establishing a downlink dedicated physical channel (DL-DPCH), establishing a synchronization with the target cell, and establishing an uplink dedicated physical channel (UL-DPCH) subsequent to the downlink synchronization.
