Research And Implementation Of Mobile Phone's Automatic Test Interface Technology Under SME

As the development of the mobile and wireless communications technology, The concept of integrated network of Seamless Mobility begin to come out. Seamless Mobility network can make the best of advanced technology,and make the connectivity of multi-network which based on 2G/3G.Now most of the Seamless Mobility scenario are conbined with 2G/3G cellphone network and Wi-Fi/Bluetooth technology.The AP which scaned by Wi-Fi phone will not be scaned if it is turned off and there are more than one link type existed,so,on research of the Seamless Mobility scenario,we should concentrate on the complecated logic of Wi-Fi link about how to establish it in detail.The target of the paper is to verify the logic of Seamless Mobility Engine during the Wi-Fi link established, by implementing automatic test framework. In order to do that, we need to study the related knowledges of Tcl language and Socket network programming. Tcl language can be used in the operation which multi strings should be handled,and socket network programming can ensure that the communication works well between Seamless Mobility Engine and Automatic test framework.The paper mainly does the following works:First, Study and research Tcl language architecture and socket networkprogramming, master the architecture and working mechanism of development with Tcllanguage and socket network programming.Second, Analysis and research the framework and communication mechanism inSeamless Mobility Engine (SME) then confirm the requirement of the automatic testframework which is used for Seamless Mobility Engine.Third, Seamless Mobility Engine mainly focus on the logic procedure that how toestablish a Wi-Fi link, after deeply research the logic, we design and implement aautomatic test framework which can verify the logic of Seamless Mobility Engine.In phone system based on Linux kernel,this paper describes a automatic testframework which is based on Tcl script and Socket network programming under Linux.This test automatic tool can establish the Wi-Fi link using the tcl script, and the relatedlogic with Wi-Fi link can be tested and verified. The research results of this paper havebeen used during test process in Wi-Fi Phone products, and achieved greate results.
