Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-session solution is used for edge service shunting, then edge service shunting can be implemented, but the terminal device must maintain excessive configuration information to manage multiple session connections
Solution Approach 1:
The patent extracts the session management function from the terminal device and relocates it to the network side. The network manages PDU sessions and establishes direct connections between the access network and user plane function, eliminating the need for the terminal device to maintain complex configuration information while preserving edge service shunting capability.
Solution Approach 2:
The patent introduces a network-side intermediary mechanism that handles the connection management between the terminal device and the user plane function. The access network establishes direct connections through the network, acting as an intermediary that simplifies the terminal device's configuration requirements while enabling edge service shunting.
2Ease of operation
If a single-session solution is used for edge service shunting, then configuration processing on the terminal device is simplified, but network processing complexity and delay for accessing core-side PDN increases
Solution Approach 1:
The patent implements a dynamic connection management mechanism where the network can flexibly establish direct connections between the access network and user plane function based on real-time needs. This dynamic approach allows the network to optimize processing paths while maintaining simple terminal device configuration, balancing between operational ease and network processing complexity.
3Device complexity
If user-plane function is deployed in a centralized manner in core layer, then network architecture is simplified, but transmission delay and backhaul network pressure increase
Solution Approach 1:
The patent segments the user-plane function deployment by establishing direct connections between the access network and the user plane function, creating localized service areas. This segmentation allows the user plane function to be deployed closer to users without requiring complete architectural simplification, thereby reducing transmission delay and backhaul pressure while maintaining manageable network complexity.

AI summary
Disclosed are a connection management method and apparatus, and a computer storage medium. The method comprises: detecting relevant information about a terminal device; and based on the relevant information about the terminal device, determining whether to adjust the type of a connection path between the terminal device and a first forwarding plane, wherein the type of the connection path between the terminal device and the first forwarding plane at least comprises: a first-type path being a connection path directly established, by means of an access network, between the terminal device and the first forwarding plane, and a second-type path being a connection path established, by means of the access network via a second forwarding plane, between the terminal device and the first forwarding plane.
