Femtocell Aggregator Hiding Portable Base Station Topology
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cellular wireless communication systems face challenges in integrating a large number of local wireless access points without modifying existing system behavior, as they struggle to recognize and manage thousands of portable base stations as a single entity, leading to increased communication latencies and poor wireless performance.
Innovation Solution
Implementing a Femtocell Access Point (FAP) aggregator that modifies communication protocol packets to present a large number of portable base stations as a single or few stationary base stations to the core network, using identifier mapping and aggregation techniques to hide the many-end-point topology and reduce latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the core network directly manages thousands of portable base stations, then network coverage and capacity are improved, but communication latency increases and system performance deteriorates
Solution Approach 1:
The patent merges multiple portable base stations into a single logical entity by aggregating their identifiers. The FAP aggregator collects identifiers from multiple portable base stations and replaces them with a single aggregate identifier in packets sent to the core network, making the core network perceive them as one base station rather than managing thousands of individual entries.
Solution Approach 2:
The FAP aggregator acts as an intermediary between portable base stations and the core network. It sits in the communication path, receives packets from portable base stations, modifies identifiers, and forwards modified packets to the core network, thereby mediating the interaction and reducing the complexity burden on the core network.
2Quantity of substance
If the core network manages thousands of portable base stations individually, then network coverage is expanded, but device complexity and processing requirements increase
Solution Approach 1:
The patent combines multiple portable base station identifiers into a single aggregate identifier that the core network recognizes. This merging approach allows the core network to maintain a simplified mapping structure rather than managing thousands of individual portable base station entries, thereby reducing processing complexity while still supporting expanded network coverage.
Solution Approach 2:
The FAP aggregator serves as an intermediary that handles the complexity of managing multiple portable base stations. It performs identifier aggregation and packet modification locally, shielding the core network from the complexity of dealing with numerous portable base stations individually.
3Adaptability or versatility
If existing cellular protocols are used without modification, then system compatibility is maintained, but the ability to integrate local wireless access points is limited
Solution Approach 1:
The patent applies local quality by making protocol modifications only at the FAP aggregator level rather than throughout the entire core network. The aggregation and identifier replacement logic is implemented locally at the access point level, allowing integration of local wireless access points while maintaining existing protocol compatibility at the core network level.
