USER PLANE ENCRYPTION POLICY AT INTERWORKING HANDOVER FROM EPS AND 5GS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18037417 titled 'USER PLANE ENCRYPTION POLICY AT INTERWORKING HANDOVER FROM EPS AND 5GS
Simplified Explanation
The abstract describes a method for facilitating handover from an evolved packet system (EPS) to a fifth-generation system (5GS) in a mobile network. The method involves receiving a user plane (UP) encryption policy from a source network node and providing this policy to a target radio access network node.
- The method enables seamless handover between different generations of mobile networks.
- It involves the exchange of encryption policies between network nodes.
- The method ensures that the determined UP encryption policy is maintained during the handover process.
Potential Applications
- This technology can be applied in mobile networks to support the transition from older generations (such as 4G) to the latest fifth-generation (5G) systems.
- It can be used by network operators to enhance the performance and reliability of handover processes for mobile devices.
Problems Solved
- Seamless handover between different generations of mobile networks can be challenging due to differences in protocols and encryption mechanisms.
- This technology solves the problem of maintaining the user plane encryption policy during the handover process, ensuring secure and uninterrupted communication for mobile devices.
Benefits
- The method simplifies the handover process, reducing the potential for service disruptions or loss of connectivity.
- It improves the overall user experience by ensuring a seamless transition between different generations of mobile networks.
- The technology enhances the security of communication by maintaining the UP encryption policy during the handover process.
Original Abstract Submitted
A method performed by a target network node for interworking handover from an evolved packet system, EPS, to a fifth generation system, 5GS, in a mobile network is provided. The method includes receiving, from a source network node, a determined user plane, UP, encryption policy. The method further includes providing the determined UP encryption policy to a target radio access network node. Corresponding embodiments for methods performed by a source network node and a first target network node are also provided.
