Abstract
Methods and systems are provided to perform an adaptive access procedure on a multi-subscriber identity module (SIM) wireless communication device having at least a first SIM and a second SIM associated with a shared radio frequency (RF) resource. The wireless communication device may detect that signaling on a random access channel (RACH) is required in order to establish access to a first network on a modem stack associated with the first SIM, identify a first protection window having a duration based on timing of an expected response by the first network to signaling on the RACH, and determine whether a tune-away period to decode a paging channel in a second network supported by the second SIM is scheduled to occur within the first protection window. If so, the wireless communication device may postpone signaling on the RACH until completion of the scheduled tune-away period.
