Wireless Cellular Data Propagation via Network Slices and Multicast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for propagating data from massive sensor networks in 5G wireless cellular networks are inefficient, often requiring central servers that introduce latency and resource wastage, especially for time-sensitive applications and mobile devices that need to reconnect to different sensor networks.
Innovation Solution
Implementing a method where data is propagated through a wireless communication signal with a propagation indicator and identifiers, allowing data to be transmitted directly to specific cells and devices within the network, eliminating the need for central servers and reducing latency by using multicast addresses and network slices for efficient data distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data is propagated through a central server or cloud service, then data collection and distribution is centralized and manageable, but network latency increases and the central server becomes a bottleneck
Solution Approach 1:
The patent segments the centralized data propagation function into distributed network slices. Instead of all data flowing through a central server, the network is divided into multiple independent slices that can handle data propagation locally. This segmentation reduces the bottleneck effect and latency by allowing parallel data flows through different network paths.
Solution Approach 2:
The patent introduces a new dimension of data propagation by enabling direct device-to-device communication within network slices. This adds a spatial dimension to data flow, allowing data to move horizontally across the network rather than vertically through a central server, thereby reducing latency.
2Productivity
If consumer devices connect directly to sensor networks using short-range protocols, then scalability improves and latency reduces, but devices must be geographically close and frequent reconnections are required
Solution Approach 1:
The patent makes the cellular network infrastructure universal by enabling it to serve both traditional communication functions and direct sensor-to-consumer data propagation. The network slices can handle various types of traffic and support both stationary and mobile devices through the same infrastructure, eliminating the need for separate short-range protocol networks.
Solution Approach 2:
The patent introduces network slices as intermediaries between sensors and consumer devices. These slices act as virtual carriers that can transport data across the cellular network infrastructure, enabling devices to receive sensor data without being physically close to the sensors while maintaining direct communication benefits.
3Reliability
If data is propagated to all devices in the network, then data availability is maximized, but network traffic increases and resources are wasted
Solution Approach 1:
The patent applies local quality by configuring different network slices with specific propagation characteristics. Each slice can be tailored to propagate data only to devices that need it, based on device identifiers, subscription information, or location. This selective propagation reduces unnecessary network traffic while ensuring data reaches all relevant devices.
Solution Approach 2:
The patent implements partial action by allowing data propagation to be selective rather than universal. Network slices can propagate data to a subset of devices based on specific criteria, avoiding the excessive action of broadcasting to all devices in the network. This reduces network traffic while maintaining data availability for those who need it.
Data Source
AI summary
Methods and apparatus are disclosed for the propagation of data over a network. Data packets are transmitted with identifiers (e.g. multicast addresses) for devices or groups of devices which are to receive the data. The data packets are further transmitted with propagation indicators, indicating the cells over which the data is to be propagated (or how widely the data is to be propagated from its source). Thus only those devices 10 which are both addressed by the data packets and within the cells identified by the propagation indicator receive the data.
