Mobile Device Tuneaway Request for Wireless Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices with multiple subscriptions often experience message transmission failures during tuneaways from one network to another, leading to wasted spectrum bandwidth due to loss of synchronization with the primary network.
Innovation Solution
A mobile device can request and negotiate non-communication time periods with a wireless communication network, allowing it to tune away during specified periods without disrupting communication with the primary network, thereby preventing message transmission failures and optimizing spectrum usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile device with multiple subscriptions tunes away from the primary network to listen for data on secondary networks, then the device can access data on secondary networks, but the device goes out-of-sync with the primary network causing message transmission failures
Solution Approach 1:
The mobile device sends a tuneaway request message to the network before actually tuning away, allowing the network to be notified in advance and prepare for the upcoming tuneaway period. This preliminary notification enables the network to schedule message transmissions to occur outside the tuneaway windows, preventing message loss.
Solution Approach 2:
The network responds to the tuneaway request with a tuneaway response message that acknowledges the requested tuneaway periods. This feedback mechanism allows the network to confirm the schedule adjustments and ensures both the network and device are synchronized regarding when tuneaways will occur, maintaining reliable communication.
2Reliability
If the mobile device continuously monitors both networks, then the device can receive messages from both networks, but spectrum bandwidth is wasted due to message loss during tuneaways
Solution Approach 1:
By notifying the network in advance of intended tuneaway periods through the tuneaway request message, the device enables the network to proactively schedule message transmissions during periods when the device is available. This prevents message loss and eliminates the need for retransmissions, optimizing spectrum bandwidth utilization.
Solution Approach 2:
The mobile device autonomously manages its own tuneaway schedule by sending requests for specific tuneaway periods based on its data needs. This self-service approach allows the device to optimize its own operation while coordinating with the network, improving overall system efficiency and reducing wasted bandwidth.
