Abstract

A User Equipment (UE) that was registered on a non-preferred network operator may be forced to register immediately and seamlessly onto another available more preferred network operator by updating the EF_LOCI in the UICC with the MCCMNC (i.e. PLMN ID) of the preferred network operator and then sending the REFRESH—3G Session Reset command to the Mobile Equipment (ME).
