Network Slice Establishment via Service Server Initiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G network slice establishment processes require APPs to be architecturally upgraded and to obtain specific IDs from operators, leading to increased adaptation costs and difficulties.
Innovation Solution
A method where a service server initiates a slice establishment request, allowing a terminal to acquire a device trigger request, determine a corresponding slice configuration ID, and initiate a data path establishment request, thereby establishing an NSL without the terminal needing to initiate a slice establishment request.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal initiates a slice establishment request, then the NSL establishment can be completed, but the APP requires architectural upgrade and specific ID allocation increasing adaptation costs
Solution Approach 1:
The patent inverts the traditional initiation direction by allowing the service server to initiate the slice establishment request instead of the terminal/App. This inversion eliminates the need for App architectural upgrades and specific ID allocations, as the network side now triggers the NSL establishment based on service quality parameters received from the service server
Solution Approach 2:
The patent introduces a service quality parameter as an intermediary that carries slice establishment requirements from the service server to the terminal. This intermediary mechanism enables the terminal to establish NSL without needing direct initiation capabilities, thus avoiding App complexity while maintaining reliable NSL establishment
2Reliability
If the terminal initiates a slice establishment request, then the NSL establishment can be completed, but the adaptation cost and difficulty increase due to ID application requirements
Solution Approach 1:
By inverting the initiation direction to service server → terminal instead of terminal → network, the patent eliminates the need for App ID applications and architectural modifications, greatly simplifying the adaptation process while ensuring reliable NSL establishment through network-side control
3Ease of manufacture
If the service server initiates a slice establishment request, then the APP adaptation cost is reduced, but the terminal must process and respond to device trigger requests
Solution Approach 1:
The service quality parameter acts as an intermediary that simplifies terminal operations. The terminal only needs to process this parameter and initiate a data path establishment request, rather than handling complex slice establishment initiation, thus reducing operational complexity while enabling service server-initiated NSL establishment
Data Source
AI summary
Embodiments of this application disclose a network slice (NSL) determination method. Based on the method, a service server may actively initiate a slice establishment request in response to determining a service requirement for establishing an NSL, the slice establishment request including a service quality parameter supporting the service requirement. A terminal may acquire a first device trigger request corresponding to the slice establishment request, and determine a corresponding slice configuration identifier (ID) according to the service quality parameter in the first device trigger request, the slice configuration ID being capable of reflecting a configuration parameter of an NSL capable of supporting the service quality parameter. The terminal initiates a data path establishment request for the service server according to the slice configuration ID to complete the establishment of an NSL and a data path in the NSL in a 5th generation mobile (5G) network.
