METHOD AND APPARATUS FOR MAINTAINING PRIORITY OF VPLMN DUE TO MULTIPLE SoR SECURITY CHECK FAILURES - A simplified explanation of the abstract
This abstract first appeared for US patent application 18050380 titled 'METHOD AND APPARATUS FOR MAINTAINING PRIORITY OF VPLMN DUE TO MULTIPLE SoR SECURITY CHECK FAILURES
Simplified Explanation
The patent application relates to a method for maintaining the priority of a visited public land mobile network (VPLMN) during a network selection procedure by a user equipment (UE) in a 5G or 6G communication system.
- The method involves ignoring a pre-configured priority for a VPLMN and considering it as the lowest priority if the UE enters a certain state and does not receive second subscription-only routing (SOR) information or if the received second SOR information fails the security check.
- On the other hand, if the UE receives the second SOR information and the security check is successful before entering the state, the priority of the VPLMN is considered as the pre-configured priority and the timer associated with the unsuccessful first SOR security check is stopped.
Potential applications of this technology:
- Mobile communication systems using 5G or 6G technology can benefit from this method to maintain the priority of a VPLMN during network selection procedures.
- It can be applied in various devices such as smartphones, tablets, and other mobile devices that support 5G or 6G networks.
Problems solved by this technology:
- This method addresses the issue of maintaining the priority of a VPLMN when a UE enters a certain state and does not receive the necessary SOR information or if the received information fails the security check.
- It ensures that the VPLMN is not considered as the lowest priority in such scenarios, allowing for a more efficient network selection process.
Benefits of this technology:
- By maintaining the priority of a VPLMN, the method ensures that the UE can connect to the desired network even in specific states where SOR information may not be received or validated.
- It improves the overall user experience by reducing the chances of network selection errors and ensuring seamless connectivity to the preferred network.
Original Abstract Submitted
The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system. Embodiments herein disclose methods for maintaining priority of a VPLMN during a PLMN selection procedure by a UE. The method includes ignoring a pre-configured priority for a VPLMN and considering the VPLMN as a lowest priority in response to determining that the UE has entered a state and the second SOR information is not received before the UE enters the state or the received second SOR information security check is not successful. The method includes considering a priority of the VPLMN as the pre-configured priority by not considering the VPLMN as a lowest priority and stopping the timer associated with the “first SOR security check not successful” in response to determining that the UE receives the second SOR information and a second SOR security check is successful before the UE enters the state.
