System and Methods for Using a Radio Frequency Resource to Improve Performance on a Data Communication in a Multi-Subscriber Identity Module (SIM) Wireless Communication Device

摘要

In a multi-subscription wireless communication device with a shared radio frequency (RF) resource, when there is an active data communication associated with the first SIM, a tune-away may be performed to support a subscription on a second SIM. After tuning to the second network to receive data during an assigned time slot in a frame capable of carrying a common control channel the wireless communication device may determine whether a message granting or denying the requested channel access can be recovered or excluded, and skip receiving remaining frames for the message and stop tune-aways when a message granting the requested channel access can be excluded. In some embodiments determining whether the message can be excluded may include determining whether a signal-to-noise ratio for the received data burst is greater than 10 dB, and if so, determining whether the decoded data can be identified as part of a paging message.
