Abstract: There are presently a lot of problems in TD field test process, such as the operation of equipment is inconvenient, wireless environment is complicated, test scenarios can not be reproduced, etc. To resolve these problems, the TDSCDMA service model and the transfer model are figured out in this paper, by studying the relative 2G and 3G system theories. A method of building up a virtual field test platform under laboratory circumstance, which is based on emulating test of TD field using software and hardware. It relates and analyzes technological makeup of the testing platform, and how to work and how to promote testing efficiency, which can conveniently do a lot of testing under laboratory circumstance.

Key words: TDSCDMA, virtual field, automatic test
