Dynamic Network Name Display for Cellular Base Station Differentiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cellular networks, macrocells and small cells have different hardware and service capabilities, but are presented as homogeneous access points, making it difficult for mobile devices and users to distinguish between the services provided by each type of base station, especially in terms of data usage and available services.
Innovation Solution
A method and apparatus for a mobile device to scan for base stations, select a base station for connection, and display a network name associated with the type of base station, allowing users to differentiate between macrocells and small cells based on available services, such as displaying 'PLMN 4G' for macrocells and 'PLMN Unlimited' for small cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If macrocells and small cells are presented as homogeneous access points, then network transparency and seamless handover are achieved, but users cannot distinguish between different service capabilities and data usage policies
Solution Approach 1:
The network name display is segmented into two parts: the PLMN network name (providing network transparency) and the base station type indicator (providing service capability information). This segmentation allows both homogeneity for seamless operation and heterogeneity for information disclosure.
Solution Approach 2:
The display system applies local quality by showing different information based on the specific base station type. Macrocells show 'PLMN network name' while small cells show 'PLMN network name + BS type', providing locally adapted information quality based on the base station characteristics.
2Stability of the object's composition
If all base stations display the same network name, then network unity is maintained, but service differentiation and user awareness of data usage charges are lost
Solution Approach 1:
The network name composition is segmented to include both the unified PLMN identifier and the variable base station type indicator. This maintains network unity through the common PLMN name while enabling service differentiation through the added BS type suffix.
Solution Approach 2:
The display format applies asymmetry by treating different base station types differently: macrocells display only the PLMN name while small cells display the PLMN name plus base station type indicator, creating an asymmetric display strategy that preserves unity while enabling differentiation.
3Productivity
If small cells are deployed to extend coverage and reduce macrocell strain, then network capacity and coverage are improved, but users cannot identify available services and data usage policies
Solution Approach 1:
The system applies local quality by enhancing the display information specifically for small cells (adding the base station type indicator) while keeping macrocell displays unchanged. This provides targeted information enhancement where needed without affecting the overall network operation.
Solution Approach 2:
The base station type indicator acts as an intermediary element that bridges the gap between network capacity enhancement and user awareness. It provides the missing information link that allows users to understand service availability without disrupting the small cell deployment strategy.

AI summary
In a cellular communications network having a radio access network of macrocells and small cells, a mobile device having a UICC/SIM card is configured to change its displayed network name and functionality in accordance with whether the mobile device has connected to a macrocell or a small cell. The displayed network name information is modified to inform the user about new services or data usage restrictions.
