Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The communication system described in Document 1 has an inefficient data path between mobile terminals and stationary terminals due to the involvement of the mobile terminal ISP network, which affects connection control and authentication processes.
Innovation Solution
A communication system that allows mobile terminals to communicate with stationary terminals via femtocell base stations without traversing the mobile terminal ISP network, utilizing authentication and connection control mechanisms within the ISP network to determine and establish a direct data path for Home NW-linking services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mobile terminal accesses network via femtocell base station through mobile terminal ISP network, then connection control and authentication can be performed, but communication path becomes inefficient and traverses unnecessary network segments
Solution Approach 1:
The patent extracts the Home NW-linking service capability from the standard ISP network path. The femtocell base station directly establishes a data path with the home network, bypassing the mobile terminal ISP network for local communications. This extraction allows efficient local communication while preserving the ability to use the ISP network for external communications.
Solution Approach 2:
The patent introduces connection control means as an intermediary between the femtocell base station and the home network. This intermediary receives connection requests, determines whether to provide Home NW-linking service, and controls data path generation accordingly. It acts as a mediator that enables direct local communication while maintaining network control.
2Productivity
If direct data path is established between femtocell base station and home network, then communication efficiency improves, but connection control and authentication mechanisms become more complex
Solution Approach 1:
The connection control means is designed with multi-functionality to handle both standard ISP network connections and Home NW-linking services through a unified interface. It can determine service capability, control data path generation, and manage authentication for both connection types, reducing the need for separate control mechanisms.
3Speed
If Home NW-linking service is provided without traversing ISP network, then communication speed improves, but service control and authentication capability of ISP network is reduced
Solution Approach 1:
The patent implements feedback mechanisms where the connection control means receives connection requests from femtocell base stations, determines Home NW-linking service capability, and provides appropriate control responses. The system monitors communication patterns and can dynamically adjust data path selection, maintaining automated service control while enabling fast direct communication.
Data Source
AI summary
A communication system, in which a mobile terminal uses a data path that was generated with an ISP network by a base station in a home network to access a NW via the ISP network, includes an authentication means and connection control means in the ISP network. The base station accepts an access request from the mobile terminal and transmits information relating to the base station and the mobile terminal to the connection control means. The authentication means determines based on the information whether a linking service that connects to the home NW without traversing the ISP network can be provided to the mobile terminal, and if the linking service can be provided, notifies this information to the connection control means. Based on this notification, the connection control means requests the base station to generate a data path for providing the linking service, and the base station generates the data path.
