5G Terminal Data Network Session Management by Location
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 4G mobile communication networks, there is no method to provide data network information based on a terminal's location, establish or disconnect a data network session accordingly, and manage session availability in specific areas, limiting the ability to offer local area data network services.
Innovation Solution
A method is proposed to provide data network information to terminals, allowing them to determine if they are within an access allowed area, establish or disconnect data network sessions based on location, and manage session states by using tracking areas or cell lists to define data network access allowed areas, enabling session activation or deactivation as the terminal moves in and out of these areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data network sessions are established for all terminals regardless of location, then network coverage and service availability are improved, but network resource waste and inefficiency increase
Solution Approach 1:
The patent applies local quality by defining specific geographic areas (data network service areas) where data network sessions can be established. Terminals are allowed to access data networks only when located within their designated service areas, as determined by tracking area or cell list information. This ensures services are available where needed while preventing resource waste in areas where they are not permitted.
2Productivity
If location-based session management is implemented, then network resource efficiency is improved, but system complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring data network service area information (tracking areas or cell lists) for each terminal before the terminal moves. This allows the terminal to proactively determine whether it can establish or maintain data network sessions based on its current location, without requiring complex real-time negotiations with the network. The network entity also pre-establishes the rules for session management based on location.
Solution Approach 2:
The terminal performs self-service by autonomously determining its location relative to its data network service area using the pre-provided tracking area or cell list information. The terminal independently decides whether to establish, maintain, or release data network sessions based on whether it is within the allowed area, reducing the need for complex network-controlled session management procedures.
3Productivity
If data network access is restricted to specific areas, then resource allocation efficiency is improved, but service flexibility decreases
Solution Approach 1:
The patent applies dynamics by making data network session availability dynamic based on terminal location. As terminals move between different geographic areas, their ability to establish or maintain data network sessions automatically changes. The system dynamically adjusts session states (established, suspended, or released) according to whether the terminal is within its designated data network service area, allowing efficient resource allocation while adapting to terminal mobility.
