Node Identifier String for Cell-Specific Properties in Telecommunications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In telecommunications systems, particularly in Evolved Universal Terrestrial Radio Access Network (E-UTRAN), there is a need to indicate cell characteristics to mobile terminals accessing a Home eNodeB (HeNB) to inform users of coverage and service specifics, which is not effectively addressed by existing solutions.
Innovation Solution
A method and arrangement where a node identifier string is provided to mobile terminals, indicating cell-specific properties such as node identity, charge tariffs, and performance data, through RRC connection setup messages, broadcasted information, and handover commands, allowing terminals to display and utilize these properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If cell-specific information is provided to mobile terminals in E-UTRAN networks, then user awareness of coverage and service characteristics is improved, but existing solutions only address overall cell services for all users rather than terminal-specific properties
Solution Approach 1:
The patent segments cell information into two categories: overall cell services (applicable to all users) and terminal-specific properties (applicable to individual terminals). This segmentation is achieved by introducing a terminal identifier in the RRC connection setup message that allows the network to provide customized cell-specific information to each terminal based on its capabilities and service requirements.
Solution Approach 2:
The patent performs preliminary action by including terminal-specific cell information in the RRC connection setup message during the initial connection establishment. This allows the terminal to receive and process cell-specific properties before actual data transmission begins, enabling early adaptation to cell-specific services and characteristics.
2Ease of operation
If local access services are provided through HeNB with lower charges, then user cost is reduced, but the ability to indicate specific HeNB coverage and service to end users is insufficient
Solution Approach 1:
The patent introduces an intermediary mechanism using the RRC connection setup message as a carrier to transmit cell-specific information from the HeNB to the terminal. This intermediary approach allows the network to convey detailed HeNB coverage and service information without requiring changes to the underlying HeNB architecture or user billing systems.
3Productivity
If cell-specific properties are indicated to terminals, then service optimization is improved, but the mechanism for providing terminal-specific information within existing RRC protocols is lacking
Solution Approach 1:
The patent applies universality by using the existing RRC connection setup message structure to serve multiple functions: establishing the radio resource control connection and simultaneously conveying terminal-specific cell information. This multi-functionality approach avoids creating separate signaling messages and maintains compatibility with existing RRC protocols while enabling enhanced service optimization.
