Access Gateway Policy Enforcement via Direct Session Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wireless communication networks face inefficiencies in signaling processes for creating, updating, and tearing down communication sessions, which consume resources and time, especially with the increasing usage of wireless applications.
Innovation Solution
The implementation of an Access Gateway (AGW) system with a policy enforcement component and a session control component that directly reconfigures policy decisions using Mobile IP messages, reducing the need for indirect signaling by integrating session control and policy enforcement components, such as with a Call Session Control Function (CSCF) or Packet Data Service Node (PDSN), to enforce session information and policy decisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional indirect signaling processes are used for session setup, update, and teardown, then session management can be performed with separate control and enforcement components, but signaling overhead and resource consumption increase significantly
Solution Approach 1:
The patent merges the session control component and policy enforcement component into a directly connected architecture where the session control component directly reconfigures the policy enforcement component using Mobile IP messages. This eliminates indirect signaling paths through multiple network elements, reducing signaling overhead while maintaining the functional separation needed for flexible session management.
2Productivity
If traditional indirect signaling processes are used for session management, then system modularity is maintained, but processing time and resource consumption increase
Solution Approach 1:
The session control component performs preliminary reconfiguration of the policy enforcement component by directly sending Mobile IP messages with session parameters before actual data transmission begins. This preliminary action prepares the policy enforcement component in advance, eliminating the need for subsequent signaling exchanges during active session management and reducing overall processing time.
3Loss of energy
If direct reconfiguration using Mobile IP messages is implemented, then signaling overhead is reduced, but integration complexity between components increases
Solution Approach 1:
The patent employs Mobile IP messages as a universal communication mechanism that the session control component uses to directly reconfigure the policy enforcement component. This multi-functional message format handles various session management operations (setup, update, teardown) through a single standardized interface, reducing integration complexity despite the direct connection approach.
