Radio Resource Sharing Charging for MTC and Legacy Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face inefficiencies in managing radio resources for Machine Type Communications (MTC) and non-MTC traffic, leading to high costs for service providers due to dedicated channel allocation for sporadic and low-data MTC devices, which can be alleviated by sharing radio resources between MTC and non-MTC devices.
Innovation Solution
Implementing a charging mechanism that allows base stations to schedule and share radio resources between MTC and non-MTC traffic, with the ability to collect and report resource sharing information to the core network, enabling a discount-based charging system for both types of traffic, thereby optimizing resource utilization and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated channels are allocated to MTC devices, then reliability of MTC communication is improved, but network resource utilization deteriorates
Solution Approach 1:
The patent merges MTC traffic and legacy traffic into shared radio resources, allowing both traffic types to coexist on the same resources through scheduling. This eliminates dedicated MTC channels while maintaining communication reliability through proper resource management and scheduling mechanisms.
Solution Approach 2:
The patent makes radio resources universal by enabling them to serve both MTC and legacy traffic dynamically. The scheduling mechanism allows resources to be allocated to different traffic types based on demand, making the same resources multi-functional rather than dedicated to a single traffic type.
2Productivity
If radio resources are shared between MTC and non-MTC traffic, then network resource utilization is improved, but charging accuracy deteriorates
Solution Approach 1:
The patent segments the charging mechanism by introducing separate charging parameters for MTC and legacy traffic. The base station reports resource sharing information that enables the charging system to calculate separate charges for each traffic type based on their respective resource usage, maintaining charging accuracy despite shared resources.
Solution Approach 2:
The patent implements a feedback mechanism where the base station collects and reports resource sharing information to the core network. This feedback enables the charging system to accurately determine how resources were shared and calculate appropriate charges based on actual usage patterns of each traffic type.
3Adaptability or versatility
If MTC devices transmit data periodically, then data exchange functionality is improved, but energy consumption deteriorates
Solution Approach 1:
The patent combines MTC periodic transmissions with legacy traffic on shared resources, allowing MTC devices to maintain their periodic data exchange functionality while utilizing otherwise underutilized radio resources. This reduces the need for dedicated resources and lowers overall energy consumption for achieving the same data exchange functionality.

AI summary
Systems and methods for charging in networks where radio resources are shared between Machine Type Communication (MTC) traffic and legacy traffic. A base station of a wireless access network determines a scheduling of radio resources on the air interface between MTC traffic and legacy traffic, and provides signaling to an MTC device and a legacy device indicating the scheduling of the radio resources. The base station collects resource sharing information regarding the sharing of the radio resources between the MTC traffic and the legacy traffic, and transmits a message to a network element of a core network that includes the resource sharing information. The network element may then forward the resource sharing information to a charging system so that the sharing of the radio resources is taken into account when charging the MTC device and/or the legacy device for usage of the air interface.
