Parallel Session Initiation in Wireless Network Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional wireless communication systems experience delays in setting up data sessions due to the need for a controller node to receive an update location answer from a subscriber database before initiating a new session, which increases waiting time for wireless devices to access the network.
Innovation Solution
The system allows the controller node to utilize stored information from a previous session to initiate a new session in parallel with update location procedures, transmitting a create session request without waiting for an update location answer, thereby reducing the waiting time for wireless devices to access the communication network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the controller node waits for the update location answer from the subscriber database before initiating a new session, then the authentication and location update are completed accurately, but the waiting time for wireless devices to access the network increases
Solution Approach 1:
The controller node performs preliminary actions by utilizing stored information from previous sessions to initiate the create session request before receiving the update location answer. This allows the session setup to start in advance using cached subscriber data, thereby reducing waiting time while maintaining authentication reliability through subsequent verification.
2Loss of time
If the controller node initiates a new session before receiving the update location answer, then the waiting time for wireless devices is reduced, but the session setup may lack complete location update information
Solution Approach 1:
The controller node uses preliminary action by initiating session setup before receiving complete location update answers, leveraging stored information from previous sessions. This preliminary session initiation reduces waiting time, and the system subsequently completes the location update process to ensure information completeness.
Solution Approach 2:
The stored information from previous sessions acts as an intermediary, allowing the controller node to proceed with session setup using cached data while the update location process continues in the background. This intermediary mechanism enables parallel processing of session initiation and location update operations.
3Productivity
If the system follows traditional call flows with sequential processing, then the procedure is simple and reliable, but the data path setup is slow
Solution Approach 1:
The system implements preliminary action by using stored information from previous sessions to initiate create session requests before receiving update location answers. This parallel processing approach increases data path setup speed by overlapping previously sequential operations, while the controller node manages the added complexity through coordinated request handling.

AI summary
In systems and methods of establishing an attachment between a wireless device and a communication network, an attachment request is received from the wireless device, an access node, or both, and an update location request is transmitted to a subscriber database. A create session request is transmitted to a gateway node before an update location answer is received from the subscriber database.
