Core Network Slice Selection for 5G Service Requests
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The selection of core network slices in existing communication technologies is not performed in a flexible manner, failing to support customized user demands in 5G networks.
Innovation Solution
A method and device that allow terminals to select a core network slice from a set of pre-obtained slices, each with specific capability parameters and function modules, and transmit slice configuration information to the network side for flexible selection and activation of the appropriate slice for service requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If core network slicing is implemented with fixed base station functions, then network virtualization and fault isolation are achieved, but flexible selection of core network slices for customized user demands cannot be supported
Solution Approach 1:
The patent applies dynamics by enabling the base station to dynamically select from multiple pre-configured core network slice sets based on user demands. The base station transitions from a fixed function mode to a dynamic selection mode, where it can choose appropriate core network slices (first set for first user, second set for second user) according to customized requirements, thus achieving both reliability through virtualization and adaptability through flexible selection
2Adaptability or versatility
If base station functions are set daily according to maximum network functions, then comprehensive service capability is provided, but customized user demands cannot be supported
Solution Approach 1:
The patent applies segmentation by dividing core network functions into multiple independent slice sets (first core network slice set, second core network slice set, etc.), each optimized for different service scenarios. This allows the base station to segment its functionality and select only the relevant slice set needed for each user's customized demands, making operation easier while maintaining comprehensive service capability
Solution Approach 2:
The patent applies preliminary action by pre-configuring multiple core network slice sets in advance, each tailored for different service types. When a user connects, the base station can immediately select from these pre-prepared sets without requiring real-time configuration, thus supporting customized demands while simplifying operational complexity

AI summary
A method and a device for processing a service request are provided. The method includes: selecting, from a set of core network slices obtained in advance, a first core network slice supporting the service request when the terminal initiates the service request, wherein the set of core network slices includes a plurality of core network slices and each of the plurality of core network slices includes a core network capability parameter and/or a core network function module; transmitting slice configuration information of the first core network slice and a message of a service request to a network side.
