Terminal Network Slice Access Mode Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G network scenarios, terminals often fail to access the correct network slice due to mismatched access modes, leading to service unavailability and poor service quality.
Innovation Solution
The terminal determines the network slice type identifier based on the network service identifier and uses the corresponding access mode to access the network slice, improving the network access success rate and service quality by obtaining access information from a configuration database and detecting current network status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the terminal randomly uses an access mode to initiate network access, then the terminal can attempt to access the network slice, but the service availability deteriorates due to mismatched access modes
Solution Approach 1:
The terminal performs preliminary actions by obtaining the network slice type identifier and determining the corresponding access mode before initiating network access. This preliminary configuration ensures that the terminal uses the correct access mode (dedicated or common) for the specific network slice type, thereby avoiding service unavailability while maintaining operational simplicity
2Reliability
If the terminal uses a dedicated access network for type-A network slices, then the network access reliability improves, but the device complexity increases due to multiple access network configurations
Solution Approach 1:
The terminal applies local quality by configuring different access network types (dedicated or common) according to the specific network slice type identifier. Instead of using a uniform access method for all slices, the terminal locally adapts the access network configuration to match the service requirements of each network slice type, ensuring reliable access while managing complexity through targeted configuration
3Reliability
If the terminal obtains access information from a configuration database, then the network access success rate improves, but the loss of time increases due to database queries
Solution Approach 1:
The terminal performs preliminary action by obtaining the network slice type identifier and determining the corresponding access mode in advance, before the actual network access attempt. This preliminary configuration reduces the need for time-consuming database queries during the access process itself, as the terminal already has the necessary access information prepared
Solution Approach 2:
The terminal uses self-service by maintaining local configuration databases or caches that store access mode mappings for different network slice types. Instead of querying external databases in real-time, the terminal serves itself by retrieving pre-stored access information locally, thereby improving access success rate while minimizing time loss

AI summary
This disclosure relates to the technical field, and discloses a network access method, a terminal, an access network, and a core network. The method includes: obtaining a network service identifier of a requested network service; obtaining access information based on the network service identifier, where the access information includes a network slice identifier and a network slice type identifier that correspond to the network service identifier; determining, based on the network slice type identifier, an access mode corresponding to the network slice identifier; and accessing, based on the access mode corresponding to the network slice type, a network slice corresponding to the network slice identifier. In this disclosure, based on the network service identifier, the terminal obtains the access information that includes at least the network slice type identifier, and then accesses the network slice based on the access mode corresponding to the network slice type identifier, thereby avoiding unavailability of the service caused by a failure to correctly access the network slice and improving service quality.
