Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cellular communications networks face challenges in maintaining efficient and reliable communication for Machine Type Communication (MTC) devices, particularly those located in coverage holes or under high load conditions, due to increased network overload and degraded propagation conditions.
Innovation Solution
The system selects a device-anchor base station from candidate wireless devices to assist in data transmissions between MTC devices and base stations, using criteria such as received power and traffic patterns, to establish a connection that alleviates coverage holes and high load conditions through multi-point communication schemes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number of wireless devices is increased to support more MTC devices, then network coverage and connectivity are improved, but network overload increases and communication reliability deteriorates
Solution Approach 1:
The patent segments the network communication path by introducing device-anchor base stations as intermediate relays between MTC devices and the core network. This creates multiple communication paths and distributes the network load, preventing single-point congestion while maintaining reliable connectivity for each device.
Solution Approach 2:
The patent employs device-anchor base stations as intermediary nodes that facilitate communication between MTC devices and the network. These intermediaries relay data packets, manage connections, and coordinate communication resources, thereby improving reliability without requiring direct connection to the core network for every device.
2Area of stationary object
If MTC devices are deployed in coverage holes or indoor areas, then network coverage expansion is achieved, but propagation conditions deteriorate and communication efficiency decreases
Solution Approach 1:
The patent introduces a new dimension to the network architecture by enabling MTC devices to function as anchors for other devices. This creates a hierarchical relay structure where communication efficiency is improved through multi-hop transmission paths, allowing devices in coverage holes to access the network via intermediate anchors rather than direct connection.
Solution Approach 2:
The patent implements self-service mechanisms where MTC devices automatically select appropriate anchors and establish communication paths based on local propagation conditions. The system autonomously adapts to coverage holes and indoor environments without requiring manual configuration or network intervention.
3Measurement precision
If device-anchor base station selection is performed manually or centrally, then control precision is improved, but system complexity and setup time increase
Solution Approach 1:
The patent implements feedback mechanisms where MTC devices report their propagation conditions, signal strength, and communication quality metrics to the network. This feedback enables automatic adjustment of anchor selection and communication parameters, achieving precise control through automated response to real-time conditions rather than manual configuration.
Solution Approach 2:
The patent dynamically changes communication parameters such as transmission power, modulation schemes, and routing paths based on measured propagation conditions. The system automatically adjusts these parameters to optimize communication efficiency for each device's specific environment, eliminating the need for complex manual setup.

AI summary
Systems and methods are disclosed for providing efficient and reliable communication for wireless devices, e.g., machine type communication devices, in a cellular communications network. In one embodiment, a node of a cellular communications network is configured to select a device-anchor base station for a wireless device from candidate device-anchor base stations, where the candidate device-anchor base stations are wireless devices that satisfy one or more predefined criteria for serving as a candidate device-anchor base station and establish a connection between the wireless device and the device-anchor base station for the wireless device such that data transmissions between the wireless device and a base station of the cellular communications network are via the device-anchor base station. In this manner, communication between the wireless device and the base station is assisted by the device-anchor base station.
