Core Network Data Transmission to Device Groups
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing wireless communication protocols, sending data to multiple IoT devices, such as wearable or smart home devices, often results in resource wastage as data is sent directly to each device individually, rather than efficiently to a group, leading to inefficient use of resources.
Innovation Solution
A data transmission method and apparatus that utilizes dedicated or common transmission resources to send data to a group of devices, where the data is transmitted in a user plane between core network elements, access network elements, and user equipment, using resource attributes, group identification information, or UE-specific information to indicate the device group, allowing for efficient data delivery without the need to send data to each device separately.

Engineering Contradiction Analysis
1Loss of energy
If data is sent to each UE individually through existing protocols, then each device can receive the data, but transmission resources are wasted due to redundant data delivery to multiple devices
Solution Approach 1:
The patent merges multiple individual data transmissions to different UEs into a single group data transmission. The network device sends one copy of the data to the device group, which then distributes it to member UEs, eliminating redundant transmissions and improving resource efficiency while maintaining delivery effectiveness.
Solution Approach 2:
The patent introduces a device group as an intermediary entity between the network and individual UEs. The device group receives data from the network and acts as a distributor to member UEs, reducing the burden on the network to manage individual connections and improving overall transmission efficiency.
2Reliability
If dedicated transmission resources are allocated to each UE, then reliable data delivery is achieved, but resource utilization is inefficient due to underutilization of dedicated channels
Solution Approach 1:
The patent makes transmission resources universal by creating group-specific resources that serve multiple UEs simultaneously. Instead of dedicating resources to individual UEs, the same group resources are shared and reused across all member devices, reducing total resource consumption while maintaining reliable delivery to each UE through the group distribution mechanism.

AI summary
Provided are a data transmission method and apparatus and a computer storage medium. The method includes that: a first core network element receives data from an external network, the data being data sent to a first device group (301); and the first core network element sends the data to an access network element through a first transmission resource to enable the access network element to send the data to User Equipment (UE) in the first device group through a second transmission resource (302).
