Method and apparatus for power management of UICC

摘要

A method is disclosed for saving power in a user equipment (UE), which includes discovering at least one available access technology radio access network (RAN) having at least one access technology type, switching off power to a removable Universal Integrated Circuit Card (UICC) having subscription information for a second technology type different from a first technology type when a first technology type RAN is the only access technology RAN available, and establishing access to first technology type RAN user subscription information in a nonvolatile memory (NV) on the UE when a first technology type RAN is the only access technology RAN available.

主权项

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.
