Multi-RAT Communication Control for Lower-Power Service Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
5G devices consume significantly more power compared to 4G devices when performing similar services, leading to reduced endurance and efficiency in terminal devices.
Innovation Solution
A communication control method that allows terminals and base stations to establish an association between radio access technologies and service types, enabling dynamic switching to lower power consumption technologies based on the required service type, such as switching from 5G to 4G or 2G when less power-intensive communication is needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If 5G radio access technology is used for communication, then communication rate and bandwidth are improved, but power consumption increases significantly
Solution Approach 1:
The patent implements dynamic switching between different radio access technologies (5G, 4G, 3G, 2G) based on service requirements. The terminal device determines the appropriate RAT to use for each service type, allowing the system to adapt its communication technology dynamically rather than being locked into a single technology, thus achieving both high speed when needed and low power consumption when possible
Solution Approach 2:
The patent changes the parameter of radio access technology type based on service characteristics. By establishing an association between service types and suitable RATs, the system selects appropriate communication technologies (changing the RAT parameter) to match service requirements, enabling optimal balance between communication performance and power consumption
2Area of stationary object
If 5G radio access technology is used for communication, then communication bandwidth is improved, but device endurance is reduced
Solution Approach 1:
The system dynamically adjusts the radio access technology used based on service type and bandwidth requirements. For services that do not require high bandwidth, the system switches to lower-generation technologies (4G, 3G, or 2G), thereby conserving battery power and extending device endurance while still meeting the actual communication needs
3Adaptability or versatility
If multiple radio access technologies are supported, then service adaptability is improved, but system complexity increases
Solution Approach 1:
The terminal device autonomously determines the appropriate radio access technology for each service based on pre-configured associations between service types and RATs. The system performs self-service by automatically selecting the optimal communication technology without requiring complex external control or manual configuration, thereby managing multi-RAT complexity through intelligent automation

AI summary
A communication control method is provided. The communication control method can include sending information on radio access technologies supported by a terminal to a base station, receiving an association relationship between each of the radio access technologies and a corresponding service type from the base station, when it is required to perform communication of a service with the base station, determining a target radio access technology corresponding to the service type of the service based on the association relationship, and performing communication of the service with the base station based on the target radio access technology.
