Problems solved by technology

[0005] Among the two existing solutions, the disadvantages of field testing are time-consuming and labor-intensive, and the efficiency is very low
However, there are the following defects in the method of indoor testing: the manual attenuator needs manual operation, and unattended automatic testing cannot be realized. But it is elusive, has a large randomness, and even has a very low probability of occurrence, which greatly affects the efficiency of problem solving
In addition, because there is no frequency selection feature, the interference between cells is also very serious

[0048] image 3 The system framework of the first embodiment of the dual-mode terminal testing device of the present invention is shown. See image 3 , the dual-mode terminal testing device 1 of the present embodiment comprises a power divider 10, a low-pass filter 11, a band-pass filter 12 (such as a TD-SCDMA band-pass filter), a first program-controlled attenuator 13, a second program-controlled attenuator device 14, computer 15 and combiner 16.

[0049] The principle of the device in this embodiment is: the power divider 10 receives an input signal from the network environment of the cell, and the input signal includes but is not limited to a mixed signal of a GSM signal and a TD-SCDMA signal. The power divider 10 processes the input signal and divides it into two paths of signal output, wherein the first path signal passes through the low-pass filter 11, and because the frequency of the GSM signal is low (900 and 1800MHz), it can pass through the low-pass filter 11 , an...

[0054] Figure 4 The system framework of the second embodiment of the dual-mode terminal testing device of the present invention is shown. See Figure 4 , the dual-mode terminal testing device 2 of the present embodiment includes a power divider 20, a low-pass filter 21, a band-pass filter 22 (such as a TD-SCDMA band-pass filter), a first program-controlled attenuator 23, a second program-controlled attenuator device 24, a third programmable attenuator 25, a computer 26 and a combiner 27.

[0055] This device has two-way input signal, for the first input signal (for example being the mixed signal of GSM signal and TD-SCDMA signal) from community network environment, be divided into two-way signal output after being processed by power divider 20, the first Road signal passes through low-pass filter 21, because the frequency of GSM signal is relatively low (900 and 1800MHz), can pass through low-pass filter 21, and TD-SCDMA signal (2000MHz) is then filtered out by low-pass fil...

[0060] Figure 5 The flowchart of the third embodiment of the dual-mode terminal testing method of the present invention is shown. The dual-mode terminal testing method of this embodiment is a test for dual-mode switching, please refer to image 3 and Figure 5 , the following is a detailed description of each step in the method.

[0061] Step S10: Divide the input signal from the network environment of the cell into a first channel signal and a second channel signal.

[0062] The power divider 10 can be used to process the input signal and divide it into two signal outputs. The input signal includes but is not limited to a mixed signal of GSM signal and TD-SCDMA signal.

[0063] Step S12: output the first mode signal after the first filtering process on the first channel signal, and output the second mode signal after the second filtering process on the second channel signal.

[0064] The first signal passes through the low-pass filter 11. The GSM signal can pass through ...

Description

technical field [0001] The present invention relates to a terminal testing device and method, in particular to a device and method for mode switching and reselection testing of a dual-mode terminal. Background technique [0002] For TD-SCDMA / GSM dual-mode terminals, cell handover and cell reselection are the main problems to be solved by dual-mode terminals, and they are also the links with the largest workload in the development process of dual-mode terminals. In actual tests, some problems often occur. Problems involving cell handover and cell reselection, but the law of these problems is elusive, has a large randomness, and even the probability of occurrence is very low, which brings great opportunities for developers to solve the above problems Difficulties, often because reproducing the problem takes up a lot of time and resources, is time-consuming and laborious, and greatly affects the efficiency of problem-solving. [0003] At present, there are two main methods to ...
