SELECTING A NETWORK SLICE IDENTIFIER - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240187978 titled 'SELECTING A NETWORK SLICE IDENTIFIER
Simplified Explanation
The abstract of the patent application describes a process during PDN connection establishment in the EPC where a UE and a Session Management Entity (SME) exchange information, ensuring that the selected S-NSSAI is among the UE's subscribed S-NSSAIs before providing it to the UE.
- SME checks if selected S-NSSAI is among UE's subscribed S-NSSAIs
- Subscribed S-NSSAI is retrieved from UDM using NUDM_SDM_GET service operation
Potential Applications
This technology can be applied in telecommunications networks to ensure that the UE is connected to the appropriate network slice based on its subscribed services.
Problems Solved
1. Ensures that the UE is connected to the correct network slice 2. Prevents unauthorized access to network slices
Benefits
1. Enhanced network security 2. Efficient network resource allocation 3. Improved user experience
Potential Commercial Applications
Optimizing network slice selection in 5G networks for telecom operators.
Possible Prior Art
There may be prior art related to network slice selection and UE authentication in telecommunications networks.
What are the potential security implications of this technology?
The technology ensures that the UE is connected to the correct network slice, reducing the risk of unauthorized access to sensitive network resources.
How does this technology improve network efficiency?
By verifying that the selected S-NSSAI is among the UE's subscribed S-NSSAIs, the technology ensures efficient network resource allocation and enhances the overall network performance.
Original Abstract Submitted
during pdn connection establishment in the epc, a ue and a session management entity (sme) (e.g., pgw−c+smf) exchange information. in case the sme supports more than one s-nssai, before the sme provides an s-nssai to the ue, the sme should check such that the selected s-nssai is among the ue's subscribed s-nssais by retrieving the subscribed s-nssai from a udm using, for example, the nudm_sdm_get service operation.
