Distributed Mobile Architecture for Rural Telephony
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems are expensive to deploy and maintain, especially in rural areas, where population density is low and environmental conditions are harsh, leading to disparities in telephone penetration between urban and rural communities.
Innovation Solution
A distributed mobile architecture (DMA) system that uses a network of interconnected DMAs, each with a home location register, community location register, and authentication, authorization, and accounting module, connected via an Internet protocol network to facilitate peer-to-peer communication and hand-off calls, reducing the need for expensive infrastructure and enabling cost-effective deployment and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional cellular system with MSC, BSC, and HLR/VLR is deployed, then telephony service is provided, but deployment cost becomes prohibitively high
Solution Approach 1:
The patent segments the traditional centralized cellular system into multiple distributed mobile architectures (DMAs), each capable of independent operation. Each DMA contains localized HLR, VLR, and MSC functions, eliminating the need for expensive centralized infrastructure in rural areas while maintaining telephony service reliability
Solution Approach 2:
The patent creates simplified copies of essential cellular functions within each DMA. Rather than deploying a complete traditional cellular system, each DMA implements only the necessary core functions (HLR, VLR, MSC) in a distributed manner, reducing deployment cost while maintaining service capability
2Reliability
If a traditional cellular system is deployed, then telephony service is provided, but the system requires a minimum of ten thousand users to be economically viable
Solution Approach 1:
By segmenting the cellular system into multiple independent DMAs, each serving a small local community, the patent eliminates the need for a minimum of ten thousand users. Each DMA can economically serve just a handful of users in rural areas, making the system adaptable to low-density populations
Solution Approach 2:
The patent creates a dynamic system where DMAs can be easily added, removed, or scaled based on local user demand. This flexibility allows the system to adapt to varying user densities, from isolated rural communities with few users to more densely populated areas, without being constrained by a fixed minimum user threshold
3Reliability
If traditional cellular equipment is deployed in rural areas, then telephony service is provided, but the harsh environmental conditions make operation difficult
Solution Approach 1:
By distributing cellular functions across multiple small DMAs rather than deploying large centralized equipment, the patent reduces the environmental burden on each individual unit. Each DMA can be housed in simpler, more rugged enclosures suitable for harsh rural environments, improving operational reliability
Solution Approach 2:
The patent implements self-healing capabilities within each DMA, where the system can automatically detect and recover from environmental disruptions without requiring complex external support infrastructure. This self-service approach improves reliability in remote areas where maintenance access is difficult
Data Source
AI summary
A method includes receiving, at a first distributed mobile architecture (DMA) system, a call from a first mobile subscriber to a second mobile subscriber and determining whether the second mobile subscriber is registered with one of the first DMA system and a second DMA system based on information stored at an authentication, authorization, and accounting module. The information stored at the AAA module includes a first home location register storing information associated with mobile subscribers registered with the first DMA system and a first community location register storing information associated with a second HLR of the second DMA system.
