Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio access system attachment procedures in wireless communication networks are inefficient and time-consuming, especially in heterogeneous environments where multiple networks operate in parallel, and there is a lack of mechanisms to promote service delivery between networks controlled by different operators.
Innovation Solution
A radio access system that cooperates with other systems to securely advertise available services, using a receiving unit to receive and a broadcasting unit to broadcast advertisement information, establishing a trust relationship, and generating advertisement information in various forms to optimize resource utilization and security, allowing user terminals to receive information without registration and protecting sensitive data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a user terminal frequently determines which wireless communication network is best suited by executing service capability interrogation procedures multiple times in parallel, then the user terminal can always receive the best available wireless communication network services, but the attachment procedures take a long time and require extensive signalling
Solution Approach 1:
The patent applies preliminary action by having the home radio access system pre-advertise service capability information in visited radio access systems before the user terminal needs to attach. The service capability information is pushed to the visited network in advance, so when the user terminal performs attachment, the information is already available, eliminating the need for extensive service capability interrogation procedures after attachment.
Solution Approach 2:
The patent uses the home radio access system and visited radio access system as intermediaries to exchange service capability information before the user terminal needs to attach. Instead of the user terminal directly interrogating multiple networks, the networks themselves exchange information through an intermediary mechanism, reducing the signalling burden on the terminal and speeding up the attachment process.
2Adaptability or versatility
If multiple wireless communication networks operate in parallel and a user terminal wants to frequently determine which network is best suited, then the user terminal can select the optimal network, but service capability interrogation procedures have to be executed multiple times in parallel and constantly repeated
Solution Approach 1:
The service capability information is advertised in advance by the home radio access system to the visited radio access system before the user terminal needs to perform network selection. This preliminary action allows the user terminal to obtain service capability information without executing complex interrogation procedures multiple times, reducing signalling complexity while maintaining adaptability.
Solution Approach 2:
The patent implements a feedback mechanism where the home radio access system continuously provides service capability information to the visited radio access system. This feedback loop ensures that the user terminal always has access to current service capability information without needing to repeatedly initiate interrogation procedures, reducing the complexity of constant network selection.
3Reliability
If there are no mechanisms to promote service delivery from a first communication network to a second communication network when controlled by different operators, then network autonomy is maintained, but service delivery between networks is hindered
Solution Approach 1:
The patent uses the radio access systems themselves as intermediaries to exchange service capability information across different operator networks. The home radio access system acts as an intermediary that pushes service capability information to the visited radio access system, enabling service delivery between different operator networks without requiring complex inter-network coordination mechanisms.
Solution Approach 2:
The home radio access system autonomously performs the service capability information exchange with visited radio access systems without requiring external coordination. This self-service mechanism allows different operator networks to interoperate automatically, maintaining network autonomy while enabling service delivery continuity across networks.

AI summary
The present invention aims at an effective approach to radio access system attachment in a heterogeneous communication network environment. According to the present invention, cooperation between different radio access systems (10, 12) is executed to advertise one radio access system in another. After receipt of a secure advertisement from a control unit (16) of the advertising radio access system (12), a broadcasting unit of the receiving radio access system broadcasts advertisement information in relation to the secure advertisement in the communication network. Therefore, according to the present invention, a user terminal (20) may at any time receive broadcasted advertisement information while establishing a trusted relationship with advertiser.
