MTC Public Path Bearer for M2M Signaling Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In M2M communication networks, the existing methods require each MTC Device to establish and release a bearer connection with the MTC Server individually, leading to excessive network resource occupation and reduced service processing efficiency due to multiple signaling transmissions between network elements.
Innovation Solution
A method and system for establishing a public path in a wireless communication network, where characteristic information of the public path is obtained for MTC devices in a one-line transmission group, allowing the public path to be established and used for data transmission with the MTC Server, and then released, thereby reducing the need for repeated bearer establishment and release operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each MTC Device establishes and releases a bearer connection with the MTC Server individually, then each device can communicate independently and reliably, but network resources are excessively occupied and service processing efficiency is reduced due to multiple signaling transmissions
Solution Approach 1:
The patent merges multiple individual bearer connections into a single shared bearer connection (public path) that serves multiple MTC devices simultaneously. The network establishes one bearer connection between the base station and the MTC server that can carry traffic from multiple devices, eliminating the need for each device to establish separate connections while maintaining reliable communication for all devices.
Solution Approach 2:
The public path bearer connection is designed to serve multiple functions and multiple devices simultaneously. A single bearer connection acts as a universal communication channel that can handle traffic from any MTC device in the group, making the network infrastructure more efficient while maintaining service reliability for all devices.
2Reliability
If each MTC Device establishes and releases a bearer connection with the MTC Server individually, then device-specific communication paths are ensured, but lots of network resources are occupied due to repeated signaling transmissions between network elements
Solution Approach 1:
The patent combines multiple device-specific signaling operations into a single shared bearer establishment process. Instead of each device triggering separate bearer setup and teardown signaling, the network establishes one public path bearer that serves all devices, dramatically reducing the quantity of signaling messages and network resource consumption.
3Productivity
If a public path is established for shared use by multiple MTC Devices, then network resources are reduced and service processing efficiency is improved, but device-specific communication requirements must be managed through additional mapping mechanisms
Solution Approach 1:
The patent introduces mapping mechanisms that act as intermediaries between the shared public path and individual device communications. The base station and network elements maintain mappings between device identifiers and the shared bearer connection, enabling the network to route traffic appropriately while keeping the actual bearer connection simple and shared. This intermediary layer manages the complexity rather than requiring complex device-specific paths.
