Problems solved by technology
[0005] However, the handover test by this method requires the mobile terminal to be directly exposed to the wireless environment, and the signal interference phenomenon is very serious. Due to the interference of the wireless signal, it is easy to cause the mobile terminal to be unable to lock the signal of the desired cell, or the mobile terminal handover is relatively difficult. Difficult, the signal of the desired cell cannot be achieved, and the test accuracy is low; moreover, since the power of the signal source needs to be adjusted by operating the console software, the real-time performance is poor, which easily causes signal fluctuations, and it is difficult to conduct automated tests without interruption for a long time , the test efficiency is also low; at the same time, the radiation of wireless signals is not good for the health of test and R&D personnel

Embodiment Construction
[0022] Embodiments of the present invention provide a mobile terminal switching test method, system, and device. Each signal source and the mobile terminal are connected through an attenuator, so that the connection between the mobile terminal and the network side becomes a wired connection. At the same time, according to the set power adjustment rule Adjust the power of each attenuator, simulate the mobile terminal switching environment of wireless connection, and then complete the mobile terminal switching test according to the state of the mobile terminal. Because the interference of wireless signals is avoided, the test accuracy is improved, and the corresponding power adjustment rules can be formulated according to the items to be tested, so the test efficiency is also improved. At the same time, because it works in a wired connection environment, it can also avoid testing. And R & D personnel work in the radiation environment.

The invention discloses a test method, system and device of mobile terminal switching, relating to a communication technology. The test method comprises the steps of: changing connection between mobile terminals and a network side into wired connection by connecting each signal source with the mobile terminals through attenuators; and simultaneously regulating the power of each attenuator according to a set power regulation rule and simulating the switching environment of the mobile terminals in wireless connection, thereby completing the test of the mobile terminal switching according to the states of the mobile terminals. The interference of wireless signals is avoided so that the test accuracy is improved, the relative power regulation rule can be made according to items needing to be tested so that the test efficiency is also improved, and simultaneously, the work is performed in the wired connection environment so that the test and research personnel can be prevented from working in radiation environment.
Description
technical field [0001] The present invention relates to communication technology, in particular to a mobile terminal switching test method, system and device. Background technique [0002] With the rapid development of wireless networks, the application of mobile data services has also been widely promoted, and its commercial level is getting higher and higher, and more and more users use 3G mobile networks for data services. The most critical technology involved in this is the handover technology. Due to the limited coverage of a cell, it is inevitable that the terminal will switch the service cell when performing data services while moving, and most of the call requests, They are all triggered by handover. Therefore, the level of handover technology plays a decisive role in the reliability and commercialization of the system. It solves the potential problems of the system software and hardware when switching services occur, and achieves the purpose of mature commercial us...
