Dynamic Antenna Allocation for Dual-Modem Signal Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual-SIM dual-standby mobile phones often disconnect from the network due to poor antenna allocation, where a good antenna is fixedly allocated to one modem, causing the secondary modem to lose signal or receive a weak signal, leading to network disconnection.
Innovation Solution
An antenna allocation method that dynamically allocates a good antenna to each modem based on signal quality and preset states, ensuring that modems receive a strong signal by switching the antenna between them during overlapping or non-overlapping paging cycles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a good antenna is fixedly allocated to one modem, then the primary modem can receive a signal successfully, but the secondary modem cannot receive a signal or receives a very weak signal
Solution Approach 1:
The patent implements dynamic antenna allocation where the antenna previously fixedly allocated to the primary modem is now dynamically reassigned based on signal quality detection. The system switches antenna assignment between primary and secondary modems depending on which modem can better utilize the antenna's signal reception capability, thereby resolving the contradiction between maintaining reliable signal reception and adapting to different modem performance requirements.
Solution Approach 2:
The system changes the allocation parameter (antenna assignment) based on detected signal quality conditions. When the secondary modem detects that it cannot receive signals properly with its allocated antenna, the system changes the antenna assignment parameter to allocate the good antenna to the secondary modem instead, thus adapting to changing operational conditions and resolving the signal reception issue.
2Reliability
If each modem uses a fixed antenna, then the device complexity is low, but some modems are disconnected from the network because they cannot use a good antenna
Solution Approach 1:
The system implements self-service through automatic antenna reallocation based on signal quality detection. When a modem detects poor signal reception, it triggers the antenna allocation system to automatically reassess and reallocate the antenna without requiring external intervention or complex manual configuration, thus improving network connection reliability while keeping the system relatively simple.
Solution Approach 2:
The patent employs feedback mechanisms where modems continuously monitor signal quality and provide feedback to the antenna allocation system. Based on this feedback about signal reception performance, the system automatically adjusts antenna allocation to ensure modems are connected to the network reliably, resolving the contradiction between simplicity and connection reliability.

AI summary
The present invention relates to the communications field, and provides an antenna allocation method and a terminal, so as to enable modems to receive a signal by using a good antenna in turn. The method includes: allocating a first antenna to a first modem; and if it is determined that the first modem satisfies a preset state, allocating the first antenna to any one of N-1 modems other than the first modem.
