Solution Overview

Problem

Current wireless communication networks face challenges in adapting to multiple modulation standards and dynamically allocating bandwidth due to the varying demands of different data types, leading to idle resources and inefficient bandwidth usage.

Innovation Solution

Implementing a communications system with dynamic protocol reconfiguration and bandwidth reallocation capabilities, where a server with radio head interface modules and call processing software can adjust modulation protocols and bandwidth allocation based on demand, using digital frequency converters and configuration management units to optimize logical channel usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If hardware is purchased to operate with a single modulation standard, then the hardware can be simplified and easier to manage, but the hardware becomes idle when network demand for that modulation standard is low and cannot support other standards

Engineering Contradiction:
Improvehardware simplicityVSAvoidmodulation standard support
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent implements a single hardware platform that can support multiple modulation standards (AMPS, CDMA, WCDMA, TDMA, GSM, CDPD, EDGE, GPRS, iDEN, OFDM) through software-based reconfiguration. The radio head unit and base station controller can dynamically switch between different modulation protocols based on network demand, eliminating the need for separate dedicated hardware for each standard while maintaining hardware simplicity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system employs dynamic reconfiguration capabilities where the modulation protocol and bandwidth allocation are changed in real-time based on network conditions and demand. The base station controller can dynamically adjust the operational parameters of the radio head unit to support different modulation standards and bandwidth requirements, transforming static hardware into a dynamically adaptable system.

Inventive Principle:
Principle #15Dynamics

2Productivity

If a logical channel is configured to support wide bandwidth communication data, then the channel can handle high bandwidth data types like streaming video, but available bandwidth is wasted when the same channel is used for lower bandwidth communications like text messages

Engineering Contradiction:
Improvebandwidth allocation efficiencyVSAvoidbandwidth waste
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent implements dynamic bandwidth reallocation where the allocated bandwidth for a logical channel is adjusted based on the actual data transmission requirements. The base station controller monitors network conditions and dynamically modifies bandwidth allocation, allowing the same physical channel to operate at different bandwidth levels depending on whether it is carrying high-bandwidth video data or low-bandwidth text messages, thereby optimizing bandwidth utilization efficiency.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the bandwidth parameter dynamically based on traffic type and network demand. The base station controller modifies the operational parameters of logical channels to match the actual data transmission requirements, transitioning between different bandwidth allocations to prevent waste while ensuring adequate resources for high-bandwidth applications when needed.

Inventive Principle:
Principle #35Parameter changes

AI summary

A communications system dynamically reconfigurable for RF bandwidth and modulation protocols is disclosed. A server comprises one or more radio head interface modules and a call processing software module adapted to communicate with each other. The call processing software is adapted to perform modulation and demodulation of voice and data streams using one or more air interface protocols. A radio head unit coupled to the radio head interface module communicates with one or more subscriber units. The radio head interface module receives either air interface protocol configuration information, or RF signal bandwidth allocation information, from the call processing software module for one or more communication channels, the information providing a timing trigger and a protocol or bandwidth for one or more communication channels. The radio head interface module reconfigures itself for one or more communications channels, based on the change instructed by the call processing software.
