Solution Overview
Problem
Existing wireless communication systems face network congestion due to the lack of sophisticated communication management, particularly for machine-type communications, which do not differentiate between various communication needs and requirements, leading to peak traffic overload.
Innovation Solution
A method and apparatus for managing wireless communication based on network traffic levels, where wireless devices evaluate and selectively transmit data based on monitored network traffic conditions, deferring or initiating communications according to predetermined thresholds to mitigate congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication systems manage all devices equally without differentiation, then simplicity of communication management is maintained, but network congestion occurs during peak traffic
Solution Approach 1:
The patent applies local quality by differentiating communication management based on device type and traffic characteristics. Machine-type communication devices are identified and managed differently from mobile phones, with specific attention to delay-tolerant applications. This localized differentiation allows simple management for voice services while applying sophisticated management only where needed for MTC devices during peak traffic periods.
Solution Approach 2:
The patent implements dynamic communication management by adjusting transmission timing based on network conditions and device characteristics. The system dynamically determines whether to transmit immediately or defer transmission based on real-time network traffic levels and device-specific requirements, allowing the management approach to adapt between simple and sophisticated modes as conditions change.
2Reliability
If wireless communication systems dimension for peak traffic to avoid congestion, then network reliability is improved, but network resources are wasted during low traffic periods
Solution Approach 1:
The patent applies preliminary action by having machine-type communication devices evaluate network traffic conditions before transmitting data. Devices assess current network load and defer transmission until conditions are favorable, rather than transmitting immediately when data becomes available. This advance evaluation and timing adjustment prevents peak traffic overload while allowing reduced network capacity during low traffic periods.
Solution Approach 2:
The patent implements periodic action through deferred transmission scheduling where MTC devices transmit data at intervals rather than continuously. By evaluating network conditions periodically and transmitting only when appropriate, the system achieves reliable communication without requiring peak traffic capacity to be available at all times, thus improving resource utilization efficiency.
3Speed
If machine-type communication devices transmit data immediately when available, then communication speed is improved, but network congestion increases during peak demand
Solution Approach 1:
The patent applies feedback by having machine-type communication devices continuously monitor and evaluate network traffic conditions before transmitting data. The transmission decision is based on feedback from network load assessment, where devices adjust their transmission timing according to current network status. This feedback mechanism maintains fast transmission when network conditions permit while preventing congestion when load is high.
Solution Approach 2:
The patent implements dynamics by making transmission speed and timing adaptive rather than fixed. MTC devices dynamically adjust whether to transmit immediately or defer based on real-time network conditions and application requirements. This dynamic approach preserves fast communication for time-sensitive applications while allowing deferred transmission for delay-tolerant applications during peak traffic periods.
Data Source
AI summary
The present invention provides a method for managing communications of a wireless device in a wireless communication system based on network traffic level, and a wireless device comprising a control system configured to evaluate a network traffic level. The wireless device may be configured to transmit data, such as delay-tolerant data, based upon the network traffic level, for example transmitting data only under low traffic conditions. Deferring delay-tolerant communications may result in lower peak traffic conditions in the network. Evaluating the network traffic level may comprise measuring chip energy over total energy (Ec/Io), monitoring data on shared control channels such as HS-SCCH of a HSDPA system, inferring power allocated to channels by a dynamic power allocation scheme, or other methods.
