Multi-RAT Network Channel Segmentation for Energy Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current energy-saving methods in multi-RAT communication networks, which deactivate certain networks to reduce overlapping coverage, fail to support high-rate data services, leading to user experience degradation due to the inability of GSM/UMTS networks to handle such services after LTE network deactivation.
Innovation Solution
Selecting a network as the basic network in overlapping coverage areas and deactivating all or part of the common broadcast control channels of non-basic networks while retaining their service channels, allowing the non-basic network to handle high-rate data services when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If the LTE network is deactivated to reduce energy consumption, then power consumption is reduced, but high-rate data services cannot be supported
Solution Approach 1:
The patent segments the network channels into two categories: common broadcast control channels (which are deactivated for energy saving) and service channels (which are retained to maintain service capabilities). This segmentation allows the LTE network to reduce power consumption while preserving the ability to support high-rate data services when needed.
Solution Approach 2:
The patent implements dynamic channel management where the LTE network can selectively deactivate common broadcast control channels during low-traffic periods while keeping service channels active. This dynamic approach allows the system to adapt to varying traffic conditions, reducing energy consumption during off-peak hours while maintaining service capability when required.
2Loss of energy
If all channels of LTE cells are deactivated for energy saving, then energy consumption is reduced, but service setup fails for high-rate data services
Solution Approach 1:
The patent divides LTE cell channels into common broadcast control channels and service channels, deactivating only the former while retaining the latter. This segmentation ensures that energy consumption is reduced through deactivation of non-essential channels, while service channels remain active to guarantee reliable service setup for high-rate data services.
Solution Approach 2:
Instead of completely deactivating all LTE channels, the patent applies partial action by selectively deactivating only the common broadcast control channels while keeping service channels operational. This partial deactivation achieves energy savings without compromising the reliability of service setup, as the essential service channels remain available.

AI summary
Embodiments of the present invention disclose a communication method, a network device and a system for a multi-RAT network. The communication method includes: retaining, in the overlapping coverage area of a multi-RAT network, a service channel and a common broadcast control channel of a basic network, and notifying a non-basic network to deactivate all or part of the common broadcast control channels; receiving a service request initiated by a terminal via the basic network; notifying, when the basic network is incapable of bearing the service request, the non-basic network to allocate a service channel of the non-basic network for the terminal. The technical solutions provided in the embodiments of the present invention are applicable to network systems of multi-RAT networks having overlapping coverage.
