Solution Overview
Problem
Existing service signal processing methods in customer-premises equipment (CPE) are inflexible and inefficient due to reliance on a single antenna with potentially poor signal strength, leading to impeded service processing and low rates.
Innovation Solution
A method and apparatus that dynamically select a working antenna based on signal strength information of multiple antennas, allowing for switching between antennas to ensure optimal signal processing by using a radio frequency channel of the current service antenna, thereby enhancing flexibility and processing rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single current service antenna is used as the working antenna to process service signals, then the device complexity is reduced, but the service processing rate decreases and signal strength is poor
Solution Approach 1:
The patent implements dynamic antenna selection by continuously monitoring signal strength of multiple antennas and switching the working antenna based on real-time conditions. The system transitions from a static single-antenna configuration to a dynamic multi-antenna system that adapts to changing signal environments, thereby improving service processing rate without permanently increasing device complexity
Solution Approach 2:
The patent makes antennas serve multiple functions: each antenna can be a current service antenna for its dedicated service or switch to become a working antenna for another service when signal strength is sufficient. This multi-functionality allows the system to maintain simpler antenna configurations while achieving better service processing performance
2Productivity
If another service antenna is switched to the current service antenna's radio frequency channel to improve signal strength, then service processing rate improves, but signal interference may occur
Solution Approach 1:
The patent employs periodic time-slot allocation where antennas switch between serving their dedicated service and serving as working antennas for other services. By alternating roles in periodic intervals and using idle timeslots for switching operations, the system achieves better signal strength while minimizing interference through structured time-multiplexed operation
Solution Approach 2:
The patent introduces an antenna switching mechanism as an intermediary between multiple antennas and radio frequency channels. This switching intermediary manages the allocation and reallocation of antennas to different services, coordinating the transitions to prevent direct signal conflicts and interference while enabling optimal signal strength utilization
3Adaptability or versatility
If antenna switching is performed frequently to maintain optimal signal strength, then service processing flexibility improves, but service processing stability deteriorates
Solution Approach 1:
The patent implements a feedback mechanism that continuously monitors signal strength of current service antennas and compares it against thresholds. The system only triggers antenna switching when signal strength falls below acceptable levels, providing feedback-controlled stability that prevents unnecessary frequent switching while maintaining flexibility to adapt when truly needed
Solution Approach 2:
The patent changes the operational state parameter of antennas (switching between active and idle states, between current service antenna and working antenna roles) based on signal strength conditions. By controlling parameter changes only when necessary rather than continuously, the system achieves flexibility in adapting to signal conditions while maintaining stability through controlled, threshold-based transitions

AI summary
The present invention provides a service signal processing method and apparatus, and customer-premises equipment, and belongs to the antenna field. The method includes: obtaining signal strength information of a current service antenna, and obtaining signal strength information of another service antenna; selecting a working antenna according to the signal strength information of the current service antenna and the signal strength information of the another service antenna; and controlling the working antenna to process a service signal of a current service by using a radio frequency channel of the current service antenna. The working antenna determined according to the signal strength information of the current service antenna and the signal strength information of the another service antenna may be the current service antenna or may be the another service antenna. When multiple working antennas are determined, the working antennas may process a same service or may process different services. Therefore, not only a manner in which the working antenna processes a service signal of a current service is more flexible, but also it is ensured that a service antenna with good signal strength can be used as a working antenna, thereby increasing a service processing rate.
