Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile data offloading techniques in wireless communication networks are inefficient in handling complex policy requirements and deviate from defined standards, leading to suboptimal data routing and increased network costs.
Innovation Solution
A system and method utilizing an Internet Offload Gateway (IOGW) with an Intelligent Policy Manager (IPM) to determine packet types and apply operator-defined offload rules, allowing data packets to bypass the mobile operator's packet core network if specific policy rules match, thereby optimizing data routing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing mobile data offloading techniques are used to route packets based on destination network or APN, then data offloading is achieved, but the system cannot handle complex policy requirements and deviates from defined standards
Solution Approach 1:
The patent introduces a policy control mechanism that dynamically changes routing parameters based on operator-defined policies. The system evaluates multiple policy parameters (user profile, service type, network conditions) and adjusts routing decisions accordingly, enabling complex policy handling while maintaining standard compliance through structured policy evaluation frameworks.
Solution Approach 2:
The patent introduces an intermediary policy evaluation function between the packet router and the network elements. This intermediary layer interprets operator policies and mediates routing decisions, ensuring both complex policy requirements are met and standard compliance is maintained through structured policy-to-action translation.
2Reliability
If all data packets are routed through the mobile operator's packet core network (SGSN and GGSN), then standard compliance is maintained, but network congestion increases and costs rise
Solution Approach 1:
The patent segments the network traffic flow into two paths: packets requiring core network processing (for standard compliance) and packets eligible for direct offloading (for efficiency). This segmentation allows selective routing where only necessary packets traverse the full core network path, reducing congestion while maintaining compliance for required traffic.
Solution Approach 2:
The patent performs preliminary evaluation of packets at the IuPS interface to determine offloading eligibility before they enter the core network. By pre-assessing packets against policy criteria and identifying offload candidates early, the system prevents unnecessary core network traversal, improving efficiency while ensuring compliant packets are properly routed.
3Productivity
If packet inspection is performed at the IuPS interface to enable selective offloading, then network efficiency improves, but device complexity increases
Solution Approach 1:
The patent extracts the complex policy evaluation and inspection logic into a separate, dedicated module at the IuPS interface. By isolating the intelligent policy manager from the core routing function, the system achieves efficient packet inspection and offloading decisions without significantly complicating the overall gateway architecture, as the inspection functionality is modular and specialized.
Data Source
AI summary
A system and method for mobile Internet offloading in a wireless communication network are disclosed. In one embodiment, a session is established through an Internet offload gateway (IOGW) with a mobile operator network to establish a communication with a mobile device. A packet coming from the mobile device is received by an intelligent policy manager (IPM) residing in the IOGW during the session. If the received packet is a signaling packet, offload rule flags are generated and operator defined offload policy rules are then enabled. If the received packet is a data packet, it is determined whether the operator defined offload policy rules match with session information associated the data packet. If the operator defined offload policy rules match, the data packet is offloaded to the Internet. If the operator defined offload policy rules do not match, the data packet is sent to a home gateway.
