Cellular Network Connection Procedure for Intermittent M2M Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular mobile networks face inefficiencies due to the 'always connected' assumption, leading to resource wastage and increased costs, especially for M2M devices that require intermittent data transfer, as they maintain connections even when not in use, consuming resources and reducing battery life.
Innovation Solution
Implementing a method that allows user equipment to temporarily disconnect from the network between data transmissions, with parameters communicated to or from the user equipment to manage these disconnections, enabling the network to optimize resource usage and plan for more subscribers without overprovisioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user equipment maintains continuous connection to the network, then connectivity availability is improved, but resource consumption and network capacity increase
Solution Approach 1:
The patent implements periodic connection and disconnection cycles for user equipment. Devices connect to the network periodically to transmit data and then automatically disconnect for specified durations. This periodic action pattern reduces continuous resource consumption while maintaining necessary connectivity for data transmission tasks.
Solution Approach 2:
The patent introduces dynamic connection management where the connection state changes based on operational requirements. User equipment transitions between connected and disconnected states dynamically, with parameters such as minimum connection duration and maximum disconnection duration controlling the behavior. This dynamic approach allows the system to adapt connectivity to actual needs rather than maintaining static continuous connection.
2Adaptability or versatility
If the network provisions for all user equipments to be connected simultaneously, then connectivity support is improved, but network capacity and provisioning costs increase
Solution Approach 1:
The patent implements partial connection action where user equipment connects only when necessary for data transmission rather than maintaining full continuous connection. By allowing devices to disconnect during periods of no data activity, the network can support a larger number of subscribers with the same provisioning capacity, as not all devices require simultaneous full connectivity.
3Loss of energy
If user equipment disconnects automatically between data transmissions, then resource efficiency is improved, but connection management complexity increases
Solution Approach 1:
The patent manages connection complexity through parameter configuration rather than complex procedural logic. Key parameters include minimum connection duration, maximum disconnection duration, and data transmission triggers. By controlling connection behavior through configurable parameters rather than complex algorithms, the system achieves automatic disconnection functionality while keeping the management mechanism relatively simple and adaptable.

AI summary
A cellular mobile network allows a user equipment to connect to the network, the user equipment having a subscription for using the network to send data intermittently and to disconnect temporarily from the network automatically between its data transmissions. Parameters relating to the automated temporary disconnections are communicated, and data is sent from the user equipment while the user equipment is connected. The automated temporary disconnections and reconnections are detected by the network. By allowing user equipments which automatically disconnect temporarily between their data transmissions, the network need no longer provision for all such user equipments to be connected to the network simultaneously. Thus more such user equipments can be accepted as subscribers. By communicating with the user equipment about the temporary automated disconnections from the network, the network can have some control of, or at least be made aware of, the temporary automated disconnections.
