Abstract
Communication systems can enhance customer experience by quickly and efficiently associating and disassociating radio access technologies (RATs) from available networks in a deployment. In one aspect, a user equipment (UE) can optimize usage of a PLMN selector file (e.g., HPLMNwACT) stored within the subscriber identity module (SIM) that comprises a combination of mobile country code/mobile network code (MCC/MNC) data and RAT data (e.g., customized based on mobile network operator (MNO) requirements and/or deployments). Moreover, during PLMN selection, the UE can only search for a RAT that is associated with a MCC/MNC combination, resulting in faster PLMN selection and reduced UE resource consumption. Further, the PLMN selector file can be modified based on MNO preferences via an over-the-air update.
