Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User Equipment (UE) faces challenges in accurately determining local network coverage areas due to unclear granularity and increased processing complexity, leading to inefficient storage and connection establishment in Mobile Edge Computing environments.
Innovation Solution
The method involves obtaining broadcast information from a base station that includes a Local Data Network (LDN) list, allowing the UE to select a target local network identifier based on the list and establish a session connection, thereby reducing processing complexity and storage requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network side delivers local network information to the UE, then the UE can access local network services, but the UE needs to store a large amount of information about multiple local networks and their coverage areas, increasing storage requirements
Solution Approach 1:
The patent extracts only the necessary local network identifier from the broadcast information, rather than requiring the UE to store complete local network coverage area information. The network side provides targeted local network information based on UE location, extracting only what is needed for access while leaving detailed coverage management on the network side.
Solution Approach 2:
The network side performs preliminary filtering and processing of local network information before delivering it to the UE. The base station determines which local networks are relevant to the UE's current location and delivers only that specific information, rather than requiring the UE to store all possible local network data.
2Measurement precision
If the UE determines local network coverage area based on multiple location types and granularities, then the UE can accurately identify applicable local networks, but the processing complexity of the UE is increased
Solution Approach 1:
The base station performs the complex task of determining whether the UE is within a local network coverage area by comparing UE location information with configured coverage areas. This self-service approach on the network side eliminates the need for the UE to implement complex determination logic, reducing UE processing complexity while maintaining accurate coverage identification.
Solution Approach 2:
The base station acts as an intermediary between the UE and the local network determination process. Instead of the UE directly comparing its location against multiple local network coverage areas with different granularities, the base station performs this comparison and delivers the result to the UE, simplifying the UE's role to receiving and acting on the delivered information.
3Measurement precision
If the UE stores information about all local networks and their coverage areas, then the UE can determine coverage accurately, but storage resources are wasted on local networks not supported at the current location
Solution Approach 1:
The patent applies local quality by delivering local network information specific to the UE's current location rather than universal information for all locations. The base station determines which local networks are relevant to the specific location and delivers only that information, making the information quality locally optimized and avoiding storage of irrelevant data.

AI summary
This application discloses a method for establishing a local network connection, a terminal, and a network device. The method includes: obtaining, by a terminal, broadcast information sent by a base station; if the broadcast information includes a first local data network LDN list, determining a target local network identifier based on the first LDN list, where the first LDN list includes at least one local network identifier; and establishing, by the terminal, a session connection by using the target local network identifier. The method avoids storing a large amount of related information of local network coverage areas in the terminal, saves a storage resource on a terminal side, and also reduces processing complexity of the terminal when the terminal determines a local network coverage area, thereby improving local network connection efficiency.
