Server Scheduling M2M Transmissions to Reduce Network Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing load on mobile networks due to widespread adoption of mobile broadband and potential Machine-to-Machine (M2M) communication devices leads to resource utilization issues, affecting performance for both human and M2M users, causing potential load spikes and interference.
Innovation Solution
A method and server system that schedules information transmissions from information providing devices to subscriber equipment based on desired receipt times and estimated communication intensity, distributing access attempts over time to reduce simultaneous transmissions and alleviate network load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If M2M devices transmit information autonomously without scheduling, then device simplicity and ease of operation are improved, but network load increases causing performance degradation and blocking for other users
Solution Approach 1:
The patent introduces a server as an intermediary between M2M devices and the network. The server receives information from M2M devices and manages transmission timing based on network conditions and subscriber requirements, thereby reducing direct network load while maintaining autonomous device operation.
Solution Approach 2:
The system performs preliminary actions by having M2M devices send information to the server in advance, and having the server pre-schedule transmissions based on predicted network conditions and subscriber information needs, rather than transmitting directly during peak network usage periods.
2Speed
If resources are allocated to keep mobile terminals in active state for fast access, then access speed is improved, but resource utilization efficiency deteriorates due to prolonged resource allocation
Solution Approach 1:
The server performs preliminary scheduling of M2M information transmissions based on predicted network conditions and subscriber requirements. This allows the network to allocate resources efficiently only when needed, rather than maintaining continuous active states, thereby improving resource utilization while maintaining acceptable access performance.
3Productivity
If multiple M2M devices transmit simultaneously, then information delivery speed is improved, but network blocking probability increases affecting other users
Solution Approach 1:
The server acts as a buffer and mediator that collects information from multiple M2M devices and manages their transmission to the network. It schedules transmissions to avoid simultaneous access attempts, thereby reducing blocking probability while maintaining overall information delivery throughput.
Solution Approach 2:
The system implements periodic scheduling of M2M information transmissions, where the server distributes transmission opportunities over time based on network conditions and subscriber information needs, preventing simultaneous transmissions while maintaining steady information flow.

AI summary
Embodiments herein include a method in a server for scheduling of an information transmission from an information providing device to a subscriber equipment in a communication system. The method comprises determining a moment in time at which the subscriber equipment desires information. Also, an estimation of the communication intensity in the communication system at the determined moment in time is obtained. If the estimated communication intensity exceeds a certain threshold value, an appropriate period in time for the information providing device to send desired information to the subscriber equipment is calculated, based on the communication intensity in the communication system. Furthermore, a trigger signal is sent to the information providing device, requesting the information providing device at what moment in time to provide information to the subscriber equipment. A method in an information providing device is also disclosed.
