| Abstract: With the advent of intelligent medical treatment,more and more wireless mobile medical systems have been applied to clinical work in hospitals.Due to the mobile feature of these medical systems,how to ensure the routine operation of the terminals in the course of frequent movement without interruption becomes a pain point.This paper proposes a roaming scheme based on virtual technology.Through virtual technology,seamless terminal roaming is controlled by wireless network devices.The method of reducing co-channel interference by conflict control is also introduced.The test results show that,the proposed method can effectively solve the business interruption problems caused by frequent roaming of terminals,and shield the roaming difference among different medical terminals. |
