Abstract:
1. A method for saving power in a user equipment (UE), comprising: discovering that a radio access network (RAN) operating according to a first technology type is an only available RAN, wherein the UE stores subscription information corresponding to the first technology type in a non-volatile memory (NV) of the UE, and wherein the UE stores subscription information corresponding to a second technology type that is different from the first technology type in a removable Universal Integrated Circuit Card (UICC) of the UE; switching off power to the UICC based on discovering that the RAN is the only available RAN; reading the subscription information corresponding to the first technology type from the NV; and establishing access to the RAN using the subscription information corresponding to the first technology type read from the NV.
