Abstract
Methods and apparatuses are provided for providing integrity protection in a dual subscriber identity module (SIM) dual standby (DSDS) device. A first message is received on a first SIM of the DSDS device before a radio resource of the DSDS device is tuned away from the first SIM to a second SIM by performing a tune-away procedure. A second message is received after completion of the tune-away procedure. The second message is validated. It is determined whether a first payload of the first message matches a second payload of the second message, when the first message and the second message have a same message sequence number. It is determined that the second message is a duplicate message, when the first payload matches the second payload.
