Micro Network Capacity Station Power Reduction via Dynamic Channel Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio communications systems, particularly capacity stations, face high power consumption due to frequent broadcasting of system messages, leading to energy waste and increased signaling overhead when system messages change frequently.
Innovation Solution
Implementing a method where a terminal on a macro network monitors service requirements and sends a network handover instruction to switch from the macro network to a micro network only when necessary, disabling all common physical channels except the pilot channel on the micro network to reduce power consumption and signaling overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the capacity station broadcasts system messages frequently to ensure coverage and provide high-rate service, then the terminal can access the core network reliably, but the power consumption of the capacity station increases significantly
Solution Approach 1:
The patent applies dynamics by making the broadcast of system messages adaptive rather than static. The capacity station monitors terminal service requirements and dynamically adjusts its broadcasting behavior - broadcasting system messages only when terminals have service requirements, rather than continuously broadcasting. This dynamic adjustment resolves the contradiction by maintaining reliability when needed while reducing power consumption during idle periods.
Solution Approach 2:
The patent changes the parameter of system message broadcasting from continuous to conditional. By monitoring terminal service requirements and changing the broadcasting state accordingly (broadcasting only when terminals need service), the system achieves both reliable terminal access and reduced power consumption, resolving the technical contradiction between these two parameters.
2Ease of operation
If the capacity station continuously broadcasts system messages to maintain coverage, then terminals can always acquire required parameters, but signaling overhead increases and energy is wasted
Solution Approach 1:
The patent implements self-service by having terminals actively report their service requirements to the capacity station. Instead of the capacity station blindly broadcasting continuously, terminals signal their needs, and the capacity station responds by broadcasting only when necessary. This self-service mechanism eliminates energy waste while ensuring terminals can still acquire required parameters when needed.
Solution Approach 2:
The patent transforms continuous periodic broadcasting into event-driven periodic action. Rather than broadcasting at fixed continuous intervals regardless of terminal needs, the system broadcasts periodically only when triggered by terminal service requirement changes. This reduces energy waste from unnecessary broadcasting while maintaining terminal capability to acquire parameters when service requirements arise.
3Adaptability or versatility
If the capacity station maintains all common physical channels enabled to provide full service, then the terminal can access various services, but the transmit power and resource utilization are suboptimal
Solution Approach 1:
The patent applies segmentation by dividing the service provision into two states: full service mode (when terminals have service requirements) and reduced service mode (when terminals are idle). The capacity station segments its channel configuration based on actual terminal needs, enabling all common physical channels when service is required and disabling them when idle, thus achieving both adaptability and power efficiency.
Solution Approach 2:
The patent makes channel configuration dynamic by adjusting which common physical channels are enabled or disabled based on terminal service requirements. This dynamic channel management allows the capacity station to provide full service adaptability when needed while reducing transmit power and improving resource utilization during idle periods, resolving the contradiction between versatility and power efficiency.

AI summary
Embodiments of the present invention provide a communications method, device, and system. The method includes: monitoring whether a terminal on a macro network has a service requirement on a micro network, where the micro network is in the coverage area of the macro network, and all common physical channels or some common physical channels except a pilot channel on the micro network are in a disabled state; and if the terminal has a service requirement on the micro network, sending a network handover instruction that includes configuration information of the micro network to the terminal, where the network handover instruction is used to instruct the terminal to hand over from the macro network to the micro network. In the embodiments of the present invention, power consumption of a capacity station is reduced, and unnecessary power waste is reduced.
