Core Network Data Transmission for IoT Device Groups
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for data transmission in IoT device networks result in resource wastage as data is sent to each terminal individually, rather than efficiently to a device group, leading to inefficiencies in resource utilization.
Innovation Solution
A data transmission method where a core network element receives data for a device group and sends it to an access network element via dedicated or common transmission resources, using resource attributes or group identification information to ensure efficient delivery to the appropriate terminals, thereby avoiding unnecessary resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is sent to each terminal individually through direct interface, then each terminal can receive data reliably, but network resources are seriously wasted
Solution Approach 1:
The patent merges multiple individual data transmission operations into a single group-based transmission. The network side sends data to a group of terminals simultaneously through group identification information, consolidating what would otherwise be multiple separate transmission operations into one efficient operation, thereby reducing network resource consumption while maintaining reliable delivery to all group members
Solution Approach 2:
The patent introduces group identification information as an intermediary mechanism between the network and terminals. This intermediary enables the network to address multiple terminals simultaneously through a single transmission by including group identification information that allows receiving terminals to identify whether they belong to the target group, thus eliminating the need for individual addressing of each terminal
2Productivity
If dedicated transmission resources are established for device groups, then transmission efficiency is improved, but device complexity increases
Solution Approach 1:
The patent utilizes parameter changes by dynamically establishing or reusing dedicated transmission resources based on group identification information. When a group needs communication, the system can allocate specific transmission parameters (such as radio bearers, logical channels, or physical resources) dedicated to that group, optimizing transmission efficiency while allowing flexible adaptation to different group sizes and communication patterns

AI summary
Disclosed are a data transmission method and device, and a computer storage medium. The method comprises: a core network element receiving data sent by an external network, wherein the data is data to be sent to a first device group; and the core network element sending the data to an access network element by means of a first transmission resource, so that the access network element sends the data to a terminal in the first device group by means of a second transmission resource, wherein the data is transmitted on a control plane between the core network element and the access network element and between the access network element and the terminal.
