EFFICIENT RESUMPTION MECHANISM FOR GSM SERVICES IN DSDS DEVICES AFTER ACQUIRING BACK THE RF CHAIN

摘要

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.
