System Information Message Broadcast for Radio Network Service Availability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radio communication systems, mobile nodes currently cannot determine the availability of communication services until they complete the registration process, leading to inefficient service selection and potential delays due to trial and error registration attempts with networks that do not support the desired service.
Innovation Solution
A system information message is broadcast on control channels, allowing mobile nodes to detect and analyze service availability before registration, enabling informed decision-making on which network to use for communication services, thereby avoiding unnecessary registration attempts and delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile nodes perform registration with the network before determining service availability, then the registration process can be completed, but time is wasted registering with networks that do not support the desired service
Solution Approach 1:
The patent applies preliminary action by broadcasting system information messages containing service availability indicators before the registration process. Mobile nodes can detect these messages and determine which networks support the desired service in advance, performing the service availability check before committing to registration. This prevents wasted registration attempts with incompatible networks and reduces overall registration delay.
2Productivity
If system information messages are broadcast to indicate service availability, then mobile nodes can make informed network selection decisions, but the network requires additional resources to generate and transmit these messages
Solution Approach 1:
The patent uses parameter changes by encoding service availability information in existing system information message structures using bitmap fields and service availability indicators. These messages leverage existing broadcast mechanisms and channels, modifying only the information content parameters rather than creating entirely new communication protocols. This approach provides comprehensive service information while minimizing additional energy expenditure by reusing established message formats.
3Loss of time
If mobile nodes detect and analyze system information messages to determine service availability, then unnecessary registration attempts are avoided, but the mobile nodes require additional processing capability
Solution Approach 1:
The patent applies copying by using standardized system information message formats that are universally recognized and processed by mobile nodes. The service availability indicators are embedded in familiar message structures, allowing mobile nodes to use existing detection and analysis capabilities rather than requiring complex new processing logic. This reduces device complexity while enabling efficient service availability determination.

AI summary
Apparatus, and an associated method, for identifying availability of services in a radio network of a radio communication system. A system information message is generated at the radio access network that identifies the service availability of the radio network, such as by indicating the communication services supported by the network. The system information message, once generated, is communicated upon a broadcast control channel, or other appropriate channel, and delivered to a mobile node. The mobile node detects the system information message and determines the availability of services of the radio network therefrom. Selection of whether to register with the network is made responsive to whether the network supports the communication service that the mobile node intends to initiate.
