Terminal Slice Configuration for Dynamic 5G Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network slice management in 5G networks limits terminals to 8 simultaneous slices per access type, failing to account for diverse terminal capacities and growing service needs, leading to barriers in accessing multiple services with varying quality of service and security requirements.
Innovation Solution
A method for parameterizing terminal devices to dynamically adjust the number of network slices based on device characteristics, subscription data, and network policies, allowing the administration entity to reject or prioritize slice requests to optimize resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of slice identifiers is limited to 8 per access type according to current specifications, then network management is simplified and standardized, but terminals cannot access a greater number of network slices required for diverse services
Solution Approach 1:
The patent introduces dynamic parameters (maxSlicePerPDU, maxPDU) that allow the network to adaptively control the number of slices and PDU sessions per terminal based on terminal capabilities, subscription data, and network conditions. This replaces the static limit of 8 slices with a flexible configuration that can be adjusted per terminal and per network slice, resolving the contradiction between versatility and complexity.
Solution Approach 2:
The patent changes the parameter structure by introducing new parameters (maxSlicePerPDU, maxPDU, requestedMaxPDU) that modify how slice allocation works. Instead of a fixed 8-slice limit, the system now uses configurable parameters that can be set based on terminal storage capacity, processing power, and service requirements, enabling terminals to access more slices when capable while maintaining manageability.
2Adaptability or versatility
If terminals are authorized to use more network slices simultaneously, then service diversity and quality of service are improved, but terminal storage and processing resources are consumed
Solution Approach 1:
The patent applies local quality by allowing different terminals to have different maximum slice allocations based on their specific capabilities. Terminals with greater storage and processing capacity can be configured with higher maxSlicePerPDU and maxPDU values, while resource-constrained terminals receive appropriate limits. This personalized configuration enables each terminal to access the appropriate number of slices for its service needs without wasting resources.
Solution Approach 2:
The system dynamically determines the maximum number of slices and PDU sessions based on terminal capabilities reported during registration, subscription data, and current network conditions. This dynamic allocation allows terminals to access more slices when needed while automatically adapting to resource constraints, resolving the contradiction between service diversity and resource consumption.
3Ease of manufacture
If the network configures a fixed number of slices for all terminals, then network management is simplified, but it fails to account for diverse terminal capacities and service needs
Solution Approach 1:
The patent implements preliminary action by having terminals report their capabilities (maxSlicePerPDU, maxPDU, requestedMaxPDU) during the registration phase. The network uses this pre-configured information to determine appropriate slice allocations before actual service deployment. This preliminary configuration simplifies ongoing management while ensuring terminals are properly adapted to their capabilities from the start.
Solution Approach 2:
The patent transforms the network configuration from a fixed universal limit to a parameter-driven flexible system. By introducing configurable parameters (maxSlicePerPDU, maxPDU) that can be set based on terminal reports and subscription data, the network maintains simplicity through standardized parameter management while achieving high adaptability to diverse terminal capabilities and service requirements.
Data Source
AI summary
A method for parameterizing a terminal device, able to transmit and receive data on a communications network organized into network slices. The method is implemented by a network administration entity able to communicate with the terminal device via the network. The method includes: following receipt of a registration request or a data session establishment request from the terminal device, obtaining at least one slice identifier associated with said terminal device, determining a maximum number of slices accessible to said terminal device, and if the determined maximum number of slices is lower than the number of identifiers obtained, transmitting a response message to said received request to the terminal device. The response message indicates rejection of the request and/or a list of identifiers from among the obtained slice identifiers.
