Abstract: A dual SIM user equipment and a re-synchronizing method thereof are provided. The dual SIM user equipment includes a single radio frequency module, a first SIM and a second SIM. The first SIM connects with a first network via utilizing the single radio frequency module at first. The second SIM then connects with a second network via utilizing the single radio frequency module. The first SIM monitors the second SIM for determining that the second SIM disconnects from the second network. The first SIM then transmits a synchronization information to the first network for re-synchronizing to the first network while the first SIM determines that there is no data to be transmitted to the first network.

Abstract: A method to realize IP flow mobility (IFOM) between 3GPP access and non-3GPP access over GTP based interfaces is proposed. A user equipment is connected to a PDN-GW via a 3GPP access network and a non-3GPP access network. The UE transmits an IFOM triggering message to the PDN-GW, which selects IP flows to be moved based on EPS bearer ID and IP flow description. The PDN-GW sends an Update Bearer Request to a WAG or ePDG, and updates its mapping table if the Update Bearer Request is successful. The UE also updates its mapping table upon receiving an IFOM acknowledgement from the WAG or ePDG. The PDN-GW initiates a 3GPP bearer modification procedure to move the selected IP flows.
