Abstract: A method for managing radio access technology services includes: reacquiring control of a radio frequency (RF) chain of a mobile communication device by a first subscription; performing a search for a base station serving a cell in which the mobile communication device is currently located; decoding only a Frequency Control Channel (FCCH) and a Synchronization Channel (SCH) transmitted by the base station; comparing a decoded Base Station Identity Code (BSIC) with a stored BSIC of a last serving cell on which a packet switched (PS) context for a data call on the first subscription was suspended or on which idle mode operations were last performed on the first subscription; and if the decoded BSIC matches the stored BSIC, resuming the data call on the first subscription on the last serving cell.

Abstract: 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.

Abstract: A method for performing cell reselection by a wireless communication device is described. The method includes monitoring one or more neighbor cells of a same radio access technology as a serving cell while camped on the serving cell. The method also includes determining that reselection criteria is met for a target cell. The method further includes starting a reselection timer for the target cell. The method additionally includes determining whether to perform reselection to the target cell based on a target cell signal to noise ratio (SNR) and a serving cell SNR.
