Base Station Internet Connectivity via IP Tunneling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing use of Time Division Multiplex (TDM) links, such as DS1 or DS3 links, for wireless communication between base stations and service nodes is costly and time-consuming, with limited availability and poor service quality, especially in areas lacking competing service providers, and fails to efficiently support the growing demand for wireless communications with asymmetrical data applications.
Innovation Solution
Implementing a communication system where base stations establish Internet connectivity over asymmetrical digital subscriber line (ADSL), DOCSIS, IEEE 802.11, or Broadband over Power Line links to communicate with service nodes via secure Internet Protocol tunnels, allowing for dynamic registration, tunnel establishment, and service provision based on predetermined schedules or end-user activity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If TDM links (DS1 or DS3) are used to exchange user communications between base station and service node, then reliable communication service is provided, but the cost is high and the link establishment time is long
Solution Approach 1:
The patent changes the communication protocol parameters from traditional TDM (Time Division Multiplexing) to IP (Internet Protocol). This parameter change enables the use of Internet infrastructure instead of dedicated TDM links, significantly reducing link establishment time while maintaining communication reliability through IP tunneling and quality of service mechanisms.
Solution Approach 2:
The patent introduces an IP network as an intermediary between the base station and service node, replacing direct TDM link connections. This intermediary approach allows communication to occur over the existing Internet infrastructure, eliminating the need for expensive dedicated TDM links while maintaining service reliability through proper routing and tunneling protocols.
2Reliability
If TDM links are used for communication, then service quality is maintained, but service provider competition is limited and availability is poor in some areas
Solution Approach 1:
The patent makes the communication system universal by enabling base stations to connect to multiple different service providers through standard Internet Protocol interfaces. Instead of being locked into specific TDM link providers, the system can utilize any IP-based connection, including DSL, cable, wireless, or fiber, thereby increasing service provider availability and competition in areas where traditional TDM infrastructure is limited.
3Productivity
If symmetrical bandwidth is provided for communication links, then balanced data transmission is achieved, but the asymmetrical traffic pattern of modern data applications cannot be efficiently supported
Solution Approach 1:
The patent implements asymmetrical bandwidth allocation in the communication links between base stations and service nodes. The downlink (service node to base station) is allocated significantly more bandwidth than the uplink (base station to service node), matching the asymmetrical traffic pattern of modern data applications where users consume more data than they generate. This asymmetrical design optimizes productivity for data-intensive applications while maintaining the flexibility to handle varying traffic demands.

AI summary
A communication system includes a base station and a service node. The service node communicates over the Internet. The base station establishes Internet connectivity over a communication link. The base station registers with the service node over the communication link and the Internet, and the service node validates the base station during registration. The base station and service node establish a tunnel over the communication link and the Internet. The base station exchanges user communications with wireless communication devices in a wireless format. The base station and service node exchange the user communications over the tunnel. The service node processes the user communications to provide a communication service to the wireless communication devices.
