Mobile Device Packet Loss Rate Reporting for Network Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In telecommunications networks, mobile devices experience packet loss during radio operations such as signal strength measurement and cell connection management, leading to difficulties in maintaining good signal quality, especially in complex radio environments.
Innovation Solution
A method where mobile devices and network nodes determine and communicate an expected packet loss rate associated with radio operations, allowing the network to schedule packet transmissions accordingly and reduce packet loss by holding packets until the mobile device is ready to receive them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mobile device performs radio operations (signal strength measurement, cell connection management), then the mobile device can maintain communication capability and adapt to radio environment changes, but packet loss occurs during these operations
Solution Approach 1:
The network node schedules packet transmissions in advance, taking into account upcoming radio operations. By predicting when radio operations will occur and scheduling packet transmissions to avoid these times, the system proactively prevents packet loss before it happens, rather than reacting after loss occurs.
Solution Approach 2:
The mobile device reports information about its radio operations to the network node, creating a feedback loop. This feedback enables the network node to adjust packet scheduling decisions based on actual radio operation timing and duration, improving the accuracy of packet delivery timing.
2Measurement precision
If the mobile device retunes its radio to measure signal strength or manage cell connections, then the mobile device can optimize communication quality, but it fails to receive packets during the retuning period
Solution Approach 1:
The system schedules packet transmissions to occur before the mobile device retunes its radio or after it completes radio operations. By anticipating the retuning events and adjusting the transmission schedule in advance, the system ensures packets are delivered when the device is ready to receive them, eliminating reception time loss.
3Device complexity
If the network schedules packet transmissions without considering mobile device radio operations, then the network can maintain simple scheduling logic, but packet loss increases due to unsynchronized transmissions
Solution Approach 1:
The mobile device provides feedback information to the network node about its radio operation schedule. This feedback mechanism allows the network to implement sophisticated scheduling that adapts to device-specific radio operation patterns without requiring complex embedded logic within the device itself, centralizing the intelligence in the network.
Solution Approach 2:
The patent introduces scheduling information as an intermediary mechanism that coordinates between the mobile device's radio operations and network packet transmissions. This intermediary layer translates device radio operation timing into network scheduling decisions, resolving the coordination problem without direct complex interaction between device and network logic.

AI summary
According to one embodiment, an apparatus may include a memory and a processor. The memory may store control information. The processor may determine, based at least in part upon the control information, an expected packet loss rate associated with performing a radio operation. The processor may then communicate the expected packet loss rate to a network node.
