Problems solved by technology

[0006] For terminal conformance testing, it is generally necessary for a professional instrument manufacturer to develop a special system simulator, but due to the long development cycle and high development cost, it is very expensive
For quite a long period of time in the initial stage of research and development of new mobile communication standards, due to the lack of corresponding terminal conformance testing equipment, the objective evaluation of new user terminal conformance and interconnection and interoperability performance has been greatly affected.

Embodiment Construction

[0023] Such as image 3 , 4 , shown in 5, the present invention adopts the agreement emulator that comprises Iub / Abis interface to come as console, controls one or more improved base stations, and this agreement emulator is made of a high-performance computer and ATM and Composed of PCM interface board, in which the test script set is stored in the computer memory, and the simulation of the wireless network controller and the core network is completed together with the high-level protocol stack; in order to cooperate with the protocol simulator to complete the control of the terminal, some improvements need to be made to the existing base station , to add support for some specific test messages that the original base station does not support. These messages include the support of the message that the base station dynamically changes the power of the downlink Dwpts and P-CCPCH through the cell reconfiguration process after the cell is activated; -1, change the frame number co...

Abstract

The invention relates to a detecting the consistency of terminal in the mobile communication system and relative method. Wherein, said device comprises a protocol simulator and an improved base station; said protocol simulator comprises a memory storing the protocol stack and executable testing group which can simulate the wireless network controller, the processor of core network and the man-machine interactive input and output units; the processor via the asynchronous transmission mode or the impulse code modulate interface board is connected to the base station; the base station comprises a wireless interface connected to the user terminal; and said method comprises: building the test simulate network, building region, building public signal channel, and sending the system message; the tested terminal, base station and protocol simulator builds calling; relative processor triggers the test sample, to complete the test and record the result; then analyzing the tested result.

Description

technical field [0001] The invention relates to a device and method for terminal consistency testing in a mobile communication system. Background technique [0002] In recent years, the third-generation mobile communication has always been the focus of people's attention, and the third-generation mobile communication standards have gradually evolved into WCDMA (Wideband Code Division Multiple Access), CDMA2000 and TD-SCDMA (Time Division-Synchronous Code Division) after continuous integration. MultipleAccess) three major standards. Taking TD-SCDMA as an example, with the rapid development of the TD-SCDMA industry, the terminal products of many terminal manufacturers have gradually entered the integration test stage from the research and development stage, and the terminal industry chain has gradually formed. However, due to the complexity of the 3G standard, there are many different implementation methods and options in the standard, as well as a wide range of parameters. B...
