Early Data Transmission Authorization Control for Wireless Networks

The patent applies local quality by differentiating EDT authorization among different UEs based on their specific characteristics. The network operator can restrict or authorize EDT on a per-UE basis using subscription parameters stored in HSS/HLR, allowing only authorized UEs to use EDT while others use normal random access. This selective application resolves the contradiction by concentrating EDT usage rights where needed rather than universally enabling it.

The patent implements preliminary action by pre-configuring EDT authorization status in the subscription parameters stored in HSS or HLR before the UE attempts random access. The network operator预先 determines which UEs are authorized for EDT based on subscription information, and this authorization is transmitted to the UE during initial access or registration. This preliminary authorization mechanism ensures that only pre-selected UEs can use EDT, preventing resource congestion and security issues while maintaining fast access for authorized devices.

The patent applies self-service by enabling the UE to autonomously determine its EDT eligibility based on received authorization parameters. The network provides authorization indicators (such as EDT restriction parameters or barred indicators) to the UE, and the UE's random access procedure automatically adapts by selecting appropriate PRACH resources or fallback to normal access based on its authorization status. This self-service approach reduces network signaling overhead and simplifies the control mechanism while maintaining reliable resource management.
