Network Slice Discovery in Overlapping Deployments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In overlapping network slice deployments, communication devices face challenges in discovering the appropriate network slice to provide desired services due to the dynamic nature of network slices and the need to differentiate between various service-related network slices.
Innovation Solution
A method and apparatus for registering a network slice mapping between network slice identification information and type information, enabling communication devices to identify suitable network slices based on service requirements by providing information about network slice capabilities, facilitating attachment to the appropriate slice for service delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple network slices are deployed to provide diverse services, then service availability and versatility are improved, but device complexity and difficulty of slice discovery increase
Solution Approach 1:
The patent introduces a network slice information mapping mechanism that acts as an intermediary between the communication device and multiple network slices. The mapping stores correspondence relationships between network slice identification information and type information, enabling the device to efficiently discover and select appropriate slices without directly managing the complexity of multiple slice deployments.
Solution Approach 2:
The patent implements preliminary registration of network slice mapping information before actual service delivery. The network device pre-establishes the correspondence between slice identification and type information, so that when a communication device needs to discover a slice, the mapping is already prepared and can be quickly queried, avoiding real-time complexity.
2Measurement precision
If network slice mapping information is registered for all service-related network slices, then slice identification accuracy is improved, but information storage requirements and processing overhead increase
Solution Approach 1:
The patent applies local quality by making the network slice mapping information specific to each service type and network slice combination. Rather than maintaining a single comprehensive mapping for all possible slices, the system registers mapping information locally for each service-related network slice, storing only the correspondence relevant to that specific slice and its supported services.
3Adaptability or versatility
If network slices are made dynamic to adapt to changing service needs, then adaptability is improved, but reliability of slice discovery and attachment decreases
Solution Approach 1:
The patent implements a feedback mechanism where the network device monitors and manages network slice information dynamically. When network slices change or new slices are deployed, the mapping information is updated accordingly. This feedback loop ensures that the mapping remains accurate and reliable even as the network slice environment becomes more dynamic, allowing communication devices to consistently discover appropriate slices.

AI summary
There are provided measures for enabling/realizing network slice discovery in an overlapping network slice deployment. Such measures exemplarily comprise registration of a network slice mapping between a network slice identification information and a network slice type information for at least one service-related network slice in an overlapping network slice deployment, said network slice type information being indicative of a service-related capability of the at least one service-related network slice, and identification of a service-related network slice in the overlapping network slice deployment on the basis of the registered network slice mapping and a service.
