Steering of Roaming PLMN List Update and Management - A simplified explanation of the abstract

This abstract first appeared for US patent application 18324706 titled 'Steering of Roaming PLMN List Update and Management

Simplified Explanation

- The patent application is about managing a list of preferred mobile network operators (OPLMNs) and selecting a Public Land Mobile Network (PLMN) based on this list. - A User Equipment (UE) device receives an SoR container, which contains a list of OPLMNs. - The UE stores a previous list of OPLMNs on its USIM (Universal Subscriber Identity Module) memory. - The UE replaces the previous list of OPLMNs on the USIM with the list of OPLMNs from the SoR container. - The UE considers the previous list of OPLMNs as a lower priority compared to the new list stored on the USIM. - When the UE decides to switch from its current PLMN, it scans for a new PLMN based on the list of OPLMNs stored on the USIM.

Original Abstract Submitted

Apparatuses, systems, and methods for SoR list management and PLMN selection based on an SoR list. A UE may receive an SoR container which may include a list of OPLMNs. The UE may store a prior list of OPLMNs stored on a USIM of the UE on a memory of the UE. The UE replace the prior list of OPLMNs stored on the USIM with the list of OPLMNs included in the SoR container. The UE may consider the prior list of OPLMNs as a lower priority list as compared to the list of OPLMNs stored on the USIM. Additionally, in response to determining to move from a current PLMN, the UE may scan for a new PLMN based on the list of OPLMNs stored on the USIM.
