5G Service Icon Display via Frequency Band Mapping Table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G networks, user devices cannot differentiate between frequency bands and services, leading to an inability to display accurate icons and for the core network to apply appropriate policies, as only a 1-bit indicator is provided for 5G coverage, lacking information on specific frequency bands and services.
Innovation Solution
Implementing a mapping table that broadcasts frequency bands and corresponding services to user devices, allowing them to determine available services and pass band information to the core network, enabling accurate icon display and policy enforcement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a 1-bit indicator is used to indicate 5G coverage, then the system complexity is reduced, but the information completeness deteriorates
Solution Approach 1:
The patent segments the 5G service information into multiple distinguishable categories (e.g., different frequency bands like n1, n3, n5, n7, n8, n20, n25, n26, n28, n38, n41, n48, n66, n77, n78, and different services like eMBB, URLLC, mMTC). Instead of using a single 1-bit indicator, the system uses multiple bits or structured information elements to represent each segment of service information, allowing the network to indicate specific band combinations and service types available to the user device.
Solution Approach 2:
The patent transitions from a one-dimensional 1-bit indicator to a multi-dimensional information structure that encompasses frequency band identifiers, service type identifiers, and their combinations. This dimensional expansion allows the system to convey rich service information (multiple bands × multiple services) without proportionally increasing complexity, as the information is structured in a standardized format that can be efficiently processed.
2Measurement precision
If detailed frequency band and service information is broadcast to user devices, then the measurement precision is improved, but the loss of time increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring and broadcasting comprehensive frequency band and service information in advance through system information blocks (SIBs) or other standardized signaling mechanisms. This allows user devices to have the mapping information readily available before needing to make service decisions, eliminating the need for real-time information retrieval and reducing latency in service identification and icon display.
3Adaptability or versatility
If the core network is made aware of frequency band usage, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent introduces an intermediary information structure (standardized information elements containing frequency band identifiers and service type identifiers) that acts as a common language between the user device and the core network. This intermediary format allows the device to report band usage information in a standardized, pre-defined structure, reducing the processing complexity on the device side while enabling the core network to receive structured, actionable information for policy enforcement and network management.
Data Source
AI summary
A method, a device, and a non-transitory storage medium are described in which a mapping table is transmitted to a user device. The mapping table includes, for each entry, an index, a frequency band, and wireless services available on the frequency band. Index information corresponding to a frequency band and wireless service available in a location associated with the user device is communicated to the user device. An icon associated with the wireless service is displayed on a display of the user device. A network device determines that the user device is using the wireless service to communicate via a wireless network and transmits, to a core network, an indication that the user device is using the wireless service on the frequency band.
