Solution Overview
Problem
Current radio network technologies face challenges in efficiently managing access parameter configurations dynamically across different areas, leading to high power consumption and interference due to the broadcasting of extensive access information tables, and lack flexibility in adapting to changing traffic situations.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If extensive access information tables are broadcasted to provide complete access parameter configurations, then wireless devices can access the network with full information, but power consumption and interference increase significantly
Solution Approach 1:
The patent extracts only the essential access parameter configurations needed for network access from the complete access information tables. Instead of broadcasting all possible parameters, the system identifies and transmits only the critical subset required for wireless devices to establish connections, thereby reducing broadcast data volume and associated power consumption while maintaining access reliability
Solution Approach 2:
The patent changes the parameter representation by using compressed indexing instead of full parameter sets. Access parameter configurations are represented through compact indices or identifiers that reference pre-defined parameter sets, transforming the broadcast content from extensive detailed information to concise reference markers, thus reducing energy consumption while preserving access functionality
2Reliability
If extensive access information tables are broadcasted to provide complete access parameter configurations, then wireless devices can access the network with full information, but the amount of broadcasted data and interference increase
Solution Approach 1:
The patent extracts only the essential access parameter configurations needed for network access from the complete access information tables. Instead of broadcasting all possible parameters, the system identifies and transmits only the critical subset required for wireless devices to establish connections, thereby reducing broadcast data volume and associated power consumption while maintaining access reliability
Solution Approach 2:
The patent uses reference copying where complete access parameter configurations are stored in a pre-defined database or configuration store, and only references or indices to these configurations are broadcast. Wireless devices use these references to retrieve or identify the appropriate parameter sets, dramatically reducing the quantity of broadcasted information while ensuring complete and accurate parameter delivery
3Ease of operation
If traditional broadcasting methods are used to provide access information, then all wireless devices receive the same information, but flexibility in adapting to changing traffic situations is reduced
Solution Approach 1:
The patent introduces dynamic adaptability by enabling the network to selectively broadcast different access parameter configurations based on current traffic conditions, network load, and service requirements. The system can dynamically update and re-broadcast modified parameter sets or indices, allowing rapid adaptation to changing situations while maintaining the simplicity of broadcast-based distribution mechanisms
Solution Approach 2:
The patent implements periodic broadcasting of access information updates at optimized intervals. Instead of continuous broadcasting or infrequent updates, the system periodically refreshes access parameter configurations based on traffic pattern analysis, balancing the simplicity of periodic distribution with the need for dynamic adaptation to changing network conditions
4Adaptability or versatility
If comprehensive access parameter configurations are provided, then wireless devices can handle various access scenarios, but device complexity increases
Solution Approach 1:
The patent uses reference copying where complete access parameter configurations are stored in a pre-defined database or configuration store, and only references or indices to these configurations are broadcast. Wireless devices use these references to retrieve or identify the appropriate parameter sets, dramatically reducing the quantity of broadcasted information while ensuring complete and accurate parameter delivery
Solution Approach 2:
The patent creates a universal reference framework where a single broadcast message containing an index or reference can represent multiple possible access parameter configurations. The system design allows one reference mechanism to universally point to various pre-defined parameter sets, enabling devices to handle diverse access scenarios through a unified, simple reference-based approach rather than processing multiple complex configuration sets

AI summary
Methods, network nodes (300, 304) of a radio network and a wireless device (302), for controlling operation of the wireless device (302) accessing the radio network. A signalling network node (300) obtains (3:2) an access parameter configuration. The access parameter configuration is one out of a compressed set of prodefined access parameter configurations where different synchronization signals are associated with different access parameter configurations according to a predefined mapping such that a range of different synchronization signals are jointly mapped to an access parameter in the compressed set of predefined access parameter configurations. The signalling network node (300) further obtains (3:2) and signals (3:3) to the wireless device (302) a synchronization signal that is associated with the access parameter configuration according to said prodefined mapping. The wireless device (302) is then enabled to derive said access parameter configuration from the compressed set of predefined access parameter configurations based on the signalled synchronization signal and the prodefined mapping.
