Abstract:
Some example embodiments disclose methods for improving Paging Type2 performance in Dual Sim Dual Standby (DSDS) devices, wherein the methods include transmitting a status Packet Data Unit (PDU) for a Signaling Radio Bearer (SRB) to a network; initiating a first timer in response to the transmitting the status PDU; blocking a radio frequency tune away to a first Subscriber Identity Module (SIM) if one or more missing PDUs are not received before expiry of the first timer; initiating a second timer in response to the blocking the RF tune away; and retaining, by a second SIM, radio frequency resources until expiry of the second timer or the one or more missing PDUs are received from the network.
