System Information Requests With Multicast Interest Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless networks face inefficiencies in handling requests for multicast and broadcast services, leading to increased latency and signaling overhead due to the lack of explicit interest indication in system information requests.
Innovation Solution
Implementing a system where terminal nodes can indicate interest in multicast and/or broadcast services during system information requests, allowing networks to provide targeted responses, thereby reducing latency and signaling overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If terminal nodes request system information without explicit interest indication, then the system information request can be kept simple, but latency increases and signaling overhead increases
Solution Approach 1:
The terminal node performs preliminary action by including an interest indication in the system information request message before the network processes the request. This allows the network to prepare targeted responses in advance, reducing subsequent processing time and latency while maintaining request structure simplicity.
Solution Approach 2:
The interest indication acts as feedback from the terminal node to the network, providing information about the terminal's specific needs. This enables the network to adjust its response strategy dynamically, delivering only relevant system information and reducing both latency and unnecessary signaling overhead.
2Loss of information
If terminal nodes request all system information without interest indication, then comprehensive information can be obtained, but signaling overhead increases
Solution Approach 1:
The interest indication enables local quality by allowing different terminal nodes to receive different subsets of system information based on their specific needs. Instead of uniformly distributing all system information to all terminals, each terminal receives only the locally relevant information, reducing overall signaling overhead while maintaining completeness for each individual terminal.
Solution Approach 2:
The terminal node performs partial action by requesting only the specific system information it needs through the interest indication, rather than requesting all system information. This partial request strategy reduces signaling overhead while ensuring the terminal obtains sufficient information for its operations.
3Device complexity
If networks provide generic system information responses, then network processing can be simplified, but network resource utilization efficiency decreases
Solution Approach 1:
The interest indication introduces dynamics to the system information response process. Instead of static generic responses, the network dynamically adjusts its responses based on the specific interest indications received from different terminal nodes. This dynamic adaptation improves network resource utilization efficiency while the processing remains manageable through standardized response templates.
