Access Management Network Element Synchronizes 5G Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communications networks, the use of both non-3GPP and 3GPP access technologies by terminal devices can lead to resource overuse due to independent operation of these technologies, resulting in inefficient data transmission when a terminal device accesses a core network using both methods simultaneously.
Innovation Solution
A data transmission method where an access management network element or user plane data processing network element obtains information about a terminal device's connection status in one network and adjusts the data transmission procedure in another network accordingly, either restricting or resuming data transmission based on the connection status to prevent resource overuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a terminal device accesses the core network using both non-3GPP and 3GPP access technologies simultaneously, then the terminal device can utilize multiple access paths for data transmission, but resource overuse occurs due to independent operation of these access technologies
Solution Approach 1:
The patent combines the control of non-3GPP and 3GPP access technologies under a unified access management framework. The access management network element coordinates data transmission procedures across both access types, merging their independent operations into a synchronized system that prevents resource overuse while maintaining multi-access versatility.
Solution Approach 2:
The access management network element implements feedback mechanisms by obtaining connection status information from the terminal device in one network and using this information to control data transmission procedures in the other network. This feedback loop ensures that resource allocation is dynamically adjusted based on actual connection states, preventing simultaneous resource consumption through both access paths.
2Loss of energy
If the access management network element synchronizes data transmission procedures across multiple networks based on connection status, then resource utilization is optimized, but the complexity of network management increases
Solution Approach 1:
The access management network element performs multiple functions: it manages registration, controls data transmission procedures, obtains connection status information, and coordinates across different network types. By consolidating these diverse management tasks into a single multi-functional entity, the system optimizes resource utilization without proportionally increasing management complexity.
Solution Approach 2:
The access management network element proactively obtains connection status information and pre-configures data transmission procedures before actual data flow occurs. By performing preliminary actions to establish control parameters and synchronize states across networks, the system avoids complex real-time negotiations and reduces ongoing management overhead.

AI summary
Embodiments of this application provide a data transmission method and a data transmission apparatus. The method includes: obtaining, by an access management network element, information about a connection status of a terminal device in a first network; and processing, by the access management network element, a data transmission procedure of the terminal device in a second network based on the information about the connection status of the terminal device in the first network. When the terminal device needs to transmit data through both the two networks, the method in the embodiments of this application can avoid a problem that the terminal device overuses a resource in either of the networks.
