APPARATUS AND METHOD FOR SUPPORTING SESSION CONTINUITY IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18491142 titled 'APPARATUS AND METHOD FOR SUPPORTING SESSION CONTINUITY IN WIRELESS COMMUNICATION SYSTEM
Simplified Explanation
The abstract describes a method in a wireless communication system where a user equipment (UE) moves from one public land mobile network (PLMN) to another. The method involves transmitting a registration request message to an access and mobility function (AMF), receiving a registration accept message with network slice selection assistance information, determining if the network slice information matches the current session, and updating the session accordingly.
- Explanation of the patent:
- Method for UE to switch PLMNs in a wireless communication system
- Transmit registration request to AMF
- Receive registration accept message with network slice selection assistance information
- Check if network slice information matches current session
- Update session based on the result
- Potential applications of this technology:**
- Seamless handover between different mobile networks - Efficient network resource allocation for UEs
- Problems solved by this technology:**
- Simplifies the process of switching between PLMNs for UEs - Ensures smooth transition without service interruption
- Benefits of this technology:**
- Improved user experience with uninterrupted service during network transitions - Optimal network resource utilization for better performance
- Potential commercial applications of this technology:**
- Telecommunication companies for enhancing network efficiency - Mobile device manufacturers for improving user experience
- Possible prior art:**
- Prior art may include methods for network slicing in wireless communication systems - Existing techniques for UE registration and handover between PLMNs
- Unanswered questions:**
1. How does this method handle handover scenarios where multiple network slices are available in the target PLMN? 2. What security measures are in place to protect the registration process and network slice information during the handover process?
Original Abstract Submitted
A method performed by a user equipment (UE) in a wireless communication system is provided. The method includes transmitting, to an access and mobility function (AMF), a registration request message for moving to a first public land mobile network (PLMN) from a second PLMN, receiving, from the AMF, a registration accept message including first single-network slice selection assistance information (S-NSSAI) corresponding to the first PLMN of the AMF, determining whether second S-NSSAI associated with a protocol data unit (PDU) session established for the UE matches to the first S-NSSAI, wherein the second S-NSSAI corresponds to the second PLMN, and locally updating the PDU session based on a result of the determining.
