Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile wireless communication networks face challenges in effectively managing hierarchical data paths, particularly in optimizing routing and reducing handover transaction times, as current solutions are suboptimal and require manual management in complex networks.
Innovation Solution
The implementation of Data Path Anchoring (DPA) and Data Integrity Tree (DIT) Tables, which utilize routing protocols to automatically manage and provision hierarchical data paths, allowing for the selection of intermediate anchoring points based on topology and capacity information, and enabling advanced ASN architectures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If hierarchical data path anchoring is implemented with multiple intermediate anchor points, then handover transaction time is reduced and network capacity is optimized, but device complexity and management difficulty increase
Solution Approach 1:
The data path is segmented into multiple hierarchical levels with intermediate anchor points (e.g., local anchor points at base stations and remote anchor points at gateways). This segmentation allows handovers to be localized at different levels, reducing the impact on the entire data path and enabling faster handover transactions while distributing management complexity across multiple manageable segments.
Solution Approach 2:
The system performs preliminary actions by pre-establishing anchor points and pre-configuring data path segments before handovers occur. Intermediate anchor points are selected and prepared in advance based on network topology and capacity information, so that when handover is needed, the path can be switched quickly without requiring complex real-time decisions or reconfiguration of the entire data path.
2Measurement precision
If manual management of hierarchical data paths is used, then control precision is maintained, but productivity and scalability are reduced
Solution Approach 1:
The system implements self-service capabilities where the network automatically manages hierarchical data paths using routing protocols. The network entities autonomously select intermediate anchor points, establish data path segments, and perform handovers based on predefined policies and topology information, eliminating the need for manual intervention while maintaining precise control through automated decision-making algorithms.
Solution Approach 2:
The system incorporates feedback mechanisms where routing protocols continuously monitor network topology, capacity, and traffic conditions. This feedback information is used to dynamically adjust data path anchoring decisions, optimize handover timing, and reconfigure intermediate anchor points, enabling the system to adapt to changing conditions automatically while maintaining precise control over data path management.
3Stability of the object's composition
If existing routers are not affected by new data path anchoring mechanisms, then backward compatibility is maintained, but adaptability to advanced network architectures is limited
Solution Approach 1:
The system achieves universality by designing data path anchoring mechanisms that work alongside existing routers without requiring them to be replaced. The intermediate anchor points and hierarchical data path segments are implemented as additional functional layers that coexist with traditional routing, allowing the network to support both legacy and advanced architectures simultaneously. This multi-functionality enables gradual adoption of advanced features while maintaining compatibility with existing infrastructure.

AI summary
The present invention discloses a method for carrying out a handover process in a wireless network, wherein the wireless network comprises at least a first and a second base stations belonging each to a different subnet associated of that wireless network and communicating through a first and a second gateways or foreign agents, respectively, and wherein the first base station is used as a serving base station currently in communication with at least one mobile subscriber station (MS). The method provided comprises a step of determining a traffic conveying entity as an intermediate anchoring point, and when the MS moves to a second subnet which comprises the second base station, a path is established for conveying traffic to/from that MS from/to a remote destination. The path comprises the intermediate anchoring point and the first gateway (or the first foreign agent).
