Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current traffic management systems are used in wireless networks, then the system complexity remains low, but the quality of service deteriorates during high usage periods due to congestion
Solution Approach 1:
A traffic controller is introduced as an intermediary component between the wireless access network and backhaul network. This controller inspects data traffic content to determine radio bearer resource information and radio access bearer information, then manages traffic flow based on this information. The intermediary handles the complexity of monitoring and managing traffic across multiple hierarchical levels, preventing service deterioration without requiring complex changes throughout the entire network system.
Solution Approach 2:
The traffic controller implements feedback mechanisms by continuously inspecting data traffic content to determine current radio bearer resource information and radio access bearer information. Based on this feedback about network conditions, the controller dynamically manages traffic flow to maintain quality of service during high usage periods. The feedback loop enables adaptive traffic management that responds to changing network conditions.
2Productivity
If traffic management is optimized for wired networks with constant end points, then wired network efficiency is improved, but wireless network performance deteriorates due to device mobility
Solution Approach 1:
The traffic management system transitions from static wired network optimization to dynamic wireless network management. The traffic controller dynamically inspects data traffic content to determine current radio bearer resource information and radio access bearer information, adapting traffic flow management to changing network conditions and device mobility. This dynamic approach maintains network efficiency while accommodating the mobility inherent in wireless networks.
Solution Approach 2:
The system changes management parameters based on network conditions by inspecting data traffic content to determine radio bearer resource information and radio access bearer information. These parameter changes enable the system to adapt to both wired and wireless network characteristics, maintaining efficiency while supporting mobility through dynamic adjustment of traffic management parameters.
3Measurement precision
If deep packet inspection is performed to gather radio bearer resource information and radio access bearer information, then traffic management precision is improved, but processing time increases
Solution Approach 1:
The traffic controller performs preliminary inspection of data traffic content to determine radio bearer resource information and radio access bearer information before traffic flow management decisions are made. This preliminary action gathers necessary traffic information in advance, enabling precise traffic management without adding significant processing delays during critical traffic flow control operations.

AI summary
Currently, network utilization and performance are diminished due to capacity issues, which may be resolved by adding hardware/software to spread traffic uniformly according to network element usage information. Disclosed is a method of and corresponding apparatus for resolving network element capacity issues in a wireless network by inspecting data traffic content for information about wireless network elements and data traffic content, collecting said information, and managing (e.g., shaping and steering) the incoming traffic based on the information. Examples of said information include radio bearer resource information for network elements and traffic associated with a wireless access portion of the wireless network and radio access bearer information for network elements and traffic associated with a backhaul portion of the wireless network. By employing embodiments of the invention, network utilization and performance may be increased using existing wireless network elements in a manner overlaid on existing network optimization techniques (e.g., load balancing).
