PDN Connection Handover for Data Traffic and Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices continue to consume data traffic and power when the data network is disabled, as the network device can still page the primary card, leading to increased power consumption and traffic usage without user knowledge.
Innovation Solution
Establish a first PDN connection through a first mobile communication network, send registration request information to a second mobile communication network when the data network is disabled, and disconnect the first PDN connection upon handover to the second network, ensuring no further data traffic is generated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If the data network is disabled to reduce traffic consumption, then data traffic usage is reduced, but the network device can still page the primary card causing power consumption to increase
Solution Approach 1:
The patent applies preliminary action by proactively disconnecting the PDN connection when the data network is disabled or when handing over to a different mobile communication network. This prevents the network device from paging the primary card in advance, thereby avoiding unnecessary power consumption while the data network is disabled. The system anticipates the power consumption issue and takes preventive action before the paging occurs.
2Speed
If the PDN connection is maintained for seamless network handover, then network switching speed is improved, but data traffic is consumed without user knowledge when data network is disabled
Solution Approach 1:
The patent applies dynamics by making the PDN connection state dynamic rather than static. The system automatically adjusts the PDN connection status based on real-time conditions: maintaining it when the data network is enabled for seamless handover, and disconnecting it when the data network is disabled or during network handover to prevent unauthorized traffic consumption. This dynamic adjustment resolves the contradiction between maintaining connection for speed and preventing traffic loss.
3Reliability
If the first PDN connection is disconnected during network handover to comply with operator requirements, then operator compliance is improved, but network connection stability may be affected
Solution Approach 1:
The patent applies periodic action by implementing a rhythm of connecting and disconnecting the PDN connection based on specific conditions. The system periodically evaluates whether to maintain or disconnect the PDN connection based on whether the data network is enabled and whether network handover is occurring. This periodic assessment ensures operator compliance during handover while restoring connection stability when conditions are favorable, balancing both requirements.
Data Source
AI summary
This application discloses a network connection method and apparatus, an electronic device, and a readable storage medium. The method includes: establishing a first packet data network (PDN) connection through a first mobile communication network; sending registration request information to a second mobile communication network when a data network of an electronic device is in a disabled state; and disconnecting the first PDN connection when the first PDN connection is handed over from the first mobile communication network to the second mobile communication network.
