METHOD AND APPARATUS FOR MANAGING SECURITY CONTEXT RELATED TO UE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17916404 titled 'METHOD AND APPARATUS FOR MANAGING SECURITY CONTEXT RELATED TO UE
Simplified Explanation
The present patent application describes an apparatus and method for managing the security context of a User Equipment (UE) in a communication network. Here are the key points:
- The invention identifies when a UE registers with a new Access and Mobility Management Function (AMF) in the network.
- It detects the generation of a new security context by a new Authentication Server Function (AUSF) selected by the new AMF for authenticating the UE.
- It also detects the presence of one or more old security contexts related to the UE, which were generated by old AUSFs selected by old AMFs for previous authentications of the UE.
- Upon detection, the invention initiates the de-registration of the UE with the old AUSFs to manage the security context related to the UE in the network.
- This allows for the deletion of stale and inactive security contexts related to the UE, enhancing the security of communication with the UE.
Potential applications of this technology:
- Mobile communication networks
- Internet of Things (IoT) networks
- 5G and future generations of wireless networks
Problems solved by this technology:
- Inefficient management of security contexts in communication networks
- Accumulation of stale and inactive security contexts for UEs
- Potential security vulnerabilities due to the presence of multiple security contexts for a single UE
Benefits of this technology:
- Enhanced security in communication networks
- Efficient management of security contexts for UEs
- Improved network performance and resource utilization
Original Abstract Submitted
Embodiments of present disclosure relates to an apparatus and method for managing security context related to a UE. Initially, registration of a UE with a new AMF in a communication network is identified. Further, generation of new security context by new AUSF selected by the new AMF for authentication of the UE is detected. Further, presence of one or more old security contexts elated to the UE and generated by one or more old AUSFs selected by one or more old AMFs for one or more previous authentications of the UE, is detected. Upon the detection, de-registration of the UE with the one or more old AUSFs is initiated for managing security context related to the UE in the communication network. Thus, stale and inactive security context related to the UE may be deleted in the network and security of communication with the UE is enhanced.
