Mobile Device Contention Manager for Data Session Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communications devices can only support a limited number of simultaneous data connections to wireless packet data service networks, leading to contention among applications requiring constant connectivity, as existing systems lack an effective method to manage and prioritize data sessions.
Innovation Solution
A contention manager routine is executed on the mobile communications device to select and release data sessions based on various parameters such as application priority, data traffic, and connection duration, allowing for the establishment of new connections by prioritizing which applications release their data connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple applications require constant connectivity to the wireless network, then application service availability is improved, but the device cannot support all applications simultaneously due to limited data connection capacity
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting connection parameters based on application priority levels. The system assigns different priority parameters to different applications and uses these parameters to determine which connections to maintain or release when capacity is limited, thereby resolving the contradiction between service reliability and system adaptability
Solution Approach 2:
The contention manager implements self-service by automatically managing data connections without user intervention. The system autonomously monitors connection capacity, evaluates application priorities, and releases connections from lower-priority applications to maintain connections for higher-priority applications, enabling the system to adapt to changing conditions independently
2Use of energy by moving object
If the device maintains a limited number of data connections, then device resource consumption is reduced, but applications experience service disruption when connections are released
Solution Approach 1:
The system changes the parameter of connection priority dynamically, allowing it to adjust which applications maintain connections based on their priority levels. This enables the system to maintain service continuity for critical applications while releasing connections for non-critical applications, balancing resource consumption with service reliability
Solution Approach 2:
The contention manager implements feedback by continuously monitoring connection status and application priority levels. When a new connection request arrives or conditions change, the system evaluates current connections against priority parameters and makes intelligent decisions about which connections to release, ensuring that service disruption is minimized for high-priority applications
