Concurrent Network Entry Authentication and Address Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network entry processes for devices in communications systems involve sequential authentication and address allocation, leading to increased latency and prolonged time before data channels are ready for data traffic, as these processes are not executed concurrently.
Innovation Solution
A method and system where a controller independently processes authentication and address allocation requests concurrently, enabling data traffic upon successful completion of both processes, thereby reducing latency and liberalizing the timing of network entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If authentication and address allocation are processed sequentially, then processing reliability is maintained, but network entry latency increases
Solution Approach 1:
The controller initiates address allocation processing before authentication is completed. By performing address allocation in advance (preliminary action) while authentication is still in progress, the system overlaps these two previously sequential processes, thereby reducing the total network entry latency without compromising the reliability of either process since both complete successfully before data traffic is enabled.
2Productivity
If authentication and address allocation are processed concurrently, then network entry speed improves, but process coordination complexity increases
Solution Approach 1:
The controller merges the authentication process and address allocation process into a single coordinated workflow. Both processes are initiated concurrently and progress in parallel, with the controller managing both simultaneously. This merging approach improves network entry speed by eliminating sequential waiting time while the controller handles the coordination complexity of managing both processes together rather than separately.
3Reliability
If authentication completes before address allocation, then security requirements are met, but overall processing time increases
Solution Approach 1:
While maintaining security by ensuring authentication completes successfully, the controller performs address allocation as a preliminary action during the authentication process. This allows address allocation to start earlier rather than waiting for authentication to fully complete, thereby reducing authentication latency while still meeting security requirements since data traffic is only enabled after both authentication and address allocation succeed.

AI summary
A method for coordinating network entry of a device includes authenticating the device coupled to the controller, and allocating an address for the device, wherein allocating the address for the device occur concurrently with but independently of authenticating the device. The method also includes completing the network entry of the device upon successful completion of authenticating the device and allocating the address for the device.
