COORDINATED CHANGE OF PROTOCOL DATA UNIT SESSION ANCHORS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17769498 titled 'COORDINATED CHANGE OF PROTOCOL DATA UNIT SESSION ANCHORS
Simplified Explanation
The patent application describes methods and systems for coordinating the change of Protocol Data Unit (PDU) Session Anchors (PSAs). PSAs are used in redundant PDU sessions to ensure seamless handover between sessions.
- The method involves receiving a request to change the PSA for a first PDU session.
- If a second PDU session is currently undergoing a PSA change, the request to change the first PDU session is denied.
- If the second PDU session is not undergoing a PSA change, the request to change the first PDU session is granted.
- The second PDU session cannot be changed until the PSA change for the first PDU session is complete.
Potential applications of this technology:
- Mobile communication networks
- Internet of Things (IoT) networks
- Wireless communication systems
Problems solved by this technology:
- Ensures coordinated and seamless handover between redundant PDU sessions
- Prevents conflicts and disruptions during PSA changes
- Improves the reliability and performance of communication networks
Benefits of this technology:
- Reduces downtime and interruptions during PSA changes
- Enhances the overall efficiency and reliability of communication networks
- Enables smooth and uninterrupted communication for users
Original Abstract Submitted
Methods and systems for coordinated change of Protocol Data Unit (PDU) Session Anchors (PSAs) are provided. According to one embodiment, a method for coordinated change of PSAs comprises, at a node for maintaining PSA change status for PDU sessions, receiving a request for a PSA change or handover for a first PDU session having a first PSA, where the first PDU session and a second PDU session having a second PSA different from the first PSA are redundant PDU sessions with each other. If the second PDU session is undergoing a PSA change or handover, the request to change the first PDU session is denied; otherwise, the request to change the first PDU session is granted, and the second PDU session will not be allowed to be changed until the PSA change or handover for the first PDU session is complete.
