在CMU200上测试TCP/IP,EMAIL,FTP,MMS,HTTP等等的方法 test FTP,MMS,HTTP in CMU200 Rohde & Schwarz test instruments are well established in the field of radio communication and protocol testing, but some customers have identified the additional need for testing the actual data functions and applications of mobile phones under clearly defined, and reliably reproduceable, conditions. In essence, emerging technologies have demanded a broadening of the testing focus, as applications are increasingly integrated into mobile devices. The solution here described facilitates Application Testing on a network simulation of (E)GPRS, CDMA2000, or WCDMA, and requires the relevant options for the R&S CMU200. It also relies on a group of software packages, whose installation and configuration are described in this document. For all three network options, installation of the Application Test Environment (ATE) software makes available various application enablers and testcases: for example, an MMS server, with which sending and receiving MMS messages can be tested. Although the option of a live internet connection is supported for each of the network simulations, this document describes a test setup which, instead, uses a "Server PC" to provide the various required services within the simulated network. In the chapters that follow, some familiarity with IP addressing and TCP Ports is assumed, but an overview of these topics is provided in Appendix A. General guidelines are given for the whole process, from installation through to running the actual tests, and more specific guidance is given for some of the required settings (especially those which are less intuitively accessible). However, for fuller coverage, please refer to the relevant document for the product you are using. Although the current document is particularly directed towards the Universal Radio Communication Tester, i.e. the R&S CMU200, the test procedures it describes apply equally well, overall, to R&S CRTU Protocol Testers that support the same network simulations.
