Wireless Communication Device Network Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Machine-type communication devices face challenges in handling network access guidances due to unpredictable behavior of communication units, which are not aware of the controlling appliance's context, leading to potential overload and inefficiencies, especially in devices with limited power resources.
Innovation Solution
A method for a wireless communication device operating in a cellular network that includes a communication unit with a network access manager unit to interpret and handle network access guidances, providing information to the controlling appliance and allowing it to decide on the appropriate response, such as delaying or rejecting instructions, to ensure efficient data transmission and power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication unit handles network access guidance autonomously, then network access control is improved, but the controlling appliance becomes overloaded and loses context awareness
Solution Approach 1:
The patent divides the network access guidance handling into two segments: the communication unit interprets and provides information about network access guidance, while the controlling appliance makes the final decision on whether to follow it. This segmentation allows each component to focus on its strengths without being overloaded.
Solution Approach 2:
The patent introduces an intermediary information exchange mechanism where the communication unit provides information about network access guidance to the controlling appliance, which then makes the informed decision. This intermediary step ensures context awareness is maintained while distributing the handling load.
2Loss of information
If the controlling appliance handles network access guidance, then context awareness is maintained, but power consumption increases and operational simplicity is lost
Solution Approach 1:
The controlling appliance performs only the necessary partial action of making the final decision on network access guidance, rather than handling the entire guidance process. This reduces power consumption while maintaining context awareness for the critical decision-making step.
3Productivity
If the communication unit follows network access guidance, then network efficiency is improved, but adaptability to device context is reduced
Solution Approach 1:
The patent makes the network access behavior dynamic by allowing the controlling appliance to adjust the decision to follow network access guidance based on real-time device context. This enables the system to adapt between following guidance for network efficiency and deviating when device context requires it.
