Pre-established Bearers for M2M Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current mobile communications systems face inefficiencies and delays in data transmission due to the large number of Machine-to-Machine (M2M) devices accessing the network, leading to increased signaling processes and resource consumption, which affects network service processing efficiency.
Innovation Solution
The implementation of pre-setup first and second bearers between network devices and base stations allows for direct data transmission without the need for constant bearer setup and teardown, reducing signaling processes and delays, and optimizing network resource utilization by using a limited number of bearers for abundant terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional bearer setup and teardown processes are used for each MTC device data transmission, then network resource allocation can be dynamic and adaptive, but signaling processes increase and transmission delays occur
Solution Approach 1:
The patent pre-establishes multiple bearers between the base station and the first network device before MTC devices need to transmit data. These bearers are kept in a ready state and can be directly used when data transmission is needed, eliminating the need for real-time bearer setup and avoiding the associated signaling delays.
Solution Approach 2:
The pre-established bearers are not dedicated to specific MTC devices but can be shared and reused by multiple devices. When an MTC device needs to transmit data, the base station selects an appropriate pre-established bearer based on service attributes, allowing the same bearer to serve multiple different devices sequentially.
2Productivity
If bearers are established for each MTC device, then data transmission can be device-specific and optimized, but the quantity of bearers increases and network resources are consumed
Solution Approach 1:
Instead of creating dedicated bearers for each MTC device, the patent establishes a limited number of pre-configured bearers that can be shared by multiple devices. The base station selects appropriate bearers based on service attributes rather than device identity, allowing one bearer to serve multiple devices and significantly reducing the total number of bearers needed.
Solution Approach 2:
The patent merges the bearer establishment function with the data transmission function by pre-configuring bearers that can handle multiple service types. Multiple service flows from different devices are combined and transmitted through shared pre-established bearers, reducing overall bearer quantity while maintaining transmission efficiency.
3Loss of time
If pre-setup bearers are used for data transmission, then signaling processes are reduced and delays are minimized, but bearer resource allocation complexity increases
Solution Approach 1:
The patent simplifies bearer management by using service attributes as the selection criterion instead of complex device-specific configurations. The base station selects pre-established bearers based on matching service attributes (such as QoS requirements, data type, etc.), which reduces the complexity of bearer management while maintaining efficient resource allocation.
4Productivity
If traditional bearer establishment is performed for each data transmission, then network resources are allocated dynamically, but network load increases and processing efficiency decreases
Solution Approach 1:
The patent performs bearer establishment in advance during periods of low network activity, spreading out the resource consumption over time. The pre-established bearers are then reused for multiple data transmissions without requiring additional signaling or resource allocation, significantly reducing overall network resource consumption and load.

AI summary
This patent application discloses a data transmission method and system. There are one or more pre-setup first bearers between a first network device and a base station; and there are one or more pre-setup second bearers between the first network device and a second network device. The transmission method includes the following steps: receiving, by the first network device by using one first bearer, data sent by the base station, where the data is sent by a terminal to the base station by using an air interface resource, and the first bearer used to receive the data is corresponding to a first service attribute of the data; and sending, by the first network device, the data to the second network device by using one second bearer, where the second bearer used to send the data is corresponding to a second service attribute of the data.
