Description

A mobile phone radio frequency testing method

technical field

The present invention relates to a test method, in particular to a test method for mobile phone radio frequency.

Background technique

Mobile phone wireless communication is to first modulate the electrical information source (analog or digital signal) with high-frequency current (amplitude modulation or frequency modulation) to form a radio frequency signal, which is transmitted into the air through the antenna, and then the mobile phone receives the radio frequency signal and performs anti-modulation , reduced to an electrical information source. The radio frequency performance of the mobile phone is a key factor affecting the call quality of the mobile phone. Therefore, before the mobile phone leaves the factory or when there is a problem with the communication signal of the mobile phone, it is necessary to test the radio frequency performance of the mobile phone. At present, it is generally tested by corresponding testing instruments. Test the 3G network (TD-SCDMA or WCDMA) of the mobile phone first, and then test the 2G network. In the previous tests, only one test was performed. Once the indicators were found to be unqualified, it would prompt "FALL", and then re-initialize the system before proceeding to the next test. When switching from 3G test to 2G, there is a probability of handover failure, resulting in the 2G network not being effectively tested, and because it is only tested once, there is also a probability of mistesting.

Contents of the invention

The technical problem to be solved by the present invention is to provide a mobile phone radio frequency test method that improves radio frequency test efficiency and reduces false detection probability.

In order to solve the above technical problems, the present invention takes the following technical solutions:

A mobile phone radio frequency testing method, comprising the following steps:

(1) Register the mobile phone to the 3G network, and test the radio frequency indicators of the 3G network;

(2) If the first test result of the radio frequency index of the 3G network is qualified, switch from the 3G network to the 2G network; When the number of times reaches the predetermined value T, it will prompt "FALL";

(3) If the 3G network is successfully switched to the 2G network for the first time, test the radio frequency of the 2G network; When the value is X, it prompts "FALL";

(4) If the first test result of the radio frequency of the 2G network is qualified, it will prompt "PASS", and the test is over; When the preset value H is reached, it will prompt "FALL".

During the process of repeatedly testing the radio frequency of the 3G network in the step (2), when the number of failures does not reach the predetermined value T, the radio frequency of the 3G network is tested to be qualified, and the 3G network is switched to the 2G network.

In the step (3), when the 3G network is repeatedly switched to the 2G network, when the number of unsuccessful switchovers does not reach the predetermined value X, the 3G network is successfully switched to the 2G network, and the radio frequency index of the 2G network is tested.

In the process of repeatedly testing the radio frequency of the 2G network in the step (4), when the number of failures does not reach the predetermined value H, the radio frequency of the 2G network is tested to be qualified, prompting "PASS", and the test ends.

Detailed ways

In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings.

As shown in accompanying drawing 1, a kind of mobile phone radio frequency testing method comprises the following steps:

(1) Register the mobile phone to the 3G network, and test the radio frequency indicators of the 3G network;

(2) If the first test result of the radio frequency of the 3G network is qualified, switch from the 3G network to the 2G network; When the preset value T is reached, it will prompt "FALL";

(3) If the 3G network is successfully switched to the 2G network for the first time, test the radio frequency of the 2G network; When the value is X, it prompts "FALL";

(4) If the first test result of the radio frequency of the 2G network is qualified, it will prompt "PASS", and the test is over; When the preset value H is reached, it will prompt "FALL".

In the step (2), when the first 3G network radio frequency test result is unqualified, repeat the process of testing the 3G network radio frequency for many times, when the number of times the radio frequency test result is unqualified does not reach the predetermined value T, the 3G network is tested. If the network radio frequency index is qualified, the 3G network will be switched to the 2G network. That is, in the second and subsequent tests, when the number of failures has not reached the predetermined value T, if the radio frequency result of a certain test is qualified, the 3G network will be switched to the 2G network. If no qualified radio frequency result is detected until the number of failures reaches the predetermined value T, it will prompt FALL, and stop the test after prompting FALL, and do not proceed to the next step.

In the step (3), when the 3G network fails to switch to the 2G network for the first time, the 3G network repeats the process of switching to the 2G network several times. When the 2G network is successful, test the radio frequency of the 2G network. That is, in the second and subsequent handovers, when the number of unsuccessful handovers from the 3G network to the 2G network has not reached the predetermined value X, a certain handover from the 3G network to the 2G network is successful, and the radio frequency of the 2G network is tested. . If there is still no successful switching after testing until the number of unsuccessful switching times reaches the predetermined value X, then FALL will be prompted, and the test will be stopped after FALL is prompted, and the next step will not be performed.

In the step (4), when the first 2G network radio frequency result is unqualified, repeat the process of testing the 2G network radio frequency for many times, when the number of unqualified times does not reach the predetermined value H, the 2G network radio frequency index is tested to be qualified , prompting "PASS", the test is over. That is, during the second and subsequent RF tests of the 2G network, when the number of failures has not reached the predetermined value H, if a measured RF result is qualified, the test ends and PASS is prompted. If there is still no qualified radio frequency result in the test until the number of unqualified times reaches the predetermined value H, it will prompt FALL, and stop the test after prompting FALL, and do not proceed to the next step.

The predetermined value T is 3, 4, 5 or other natural numbers greater than 2, and the predetermined value X is 3, 4, 5 or other natural numbers greater than 2.

For example, if the predetermined value T is 3, if the radio frequency of the 3G network is unqualified in the first test, the second test is performed, and if the result of the second test is qualified, the 3G network is switched to the 2G network. If the result of the second test is still unqualified, the third test will be carried out. If the result of the third test is qualified, then switch from the 3G network to the 2G network. If the result of the third test is still unqualified, the number of unqualified times has reached 3 times, when the preset value T=3 is reached, it will prompt FALL, end the test, and do not proceed to the next step. Similarly, if the preset value is 4 and the previous three tests are unqualified, then continue to perform the fourth RF test, if the result of the fourth test is qualified, then switch to the 2G network, if the fourth test is still unqualified, prompt FALL, end the test. and so on.

Similarly, the 3G network is switched to the 2G network. For example, the predetermined value X is 3 times. If the first switching is unsuccessful, the second switching is performed. If the second switching is successful, the radio frequency of the 2G network is tested. If the second switching is unsuccessful, continue to the third switching. If the third switching is still unsuccessful, and the number of unsuccessful times has reached the predetermined value X=3, it will prompt FALL, end the switching, and do not proceed to the next step. step. Similarly, if the predetermined value is 4, and the previous three switchings are all unsuccessful, the fourth switching will continue. If the fourth switching is still unsuccessful, the number of unsuccessful attempts will reach the predetermined value X=4, the switching will end, and the next step will not be performed. one step. and so on.

Similarly, in the process of testing the radio frequency of the 2G network, for example, if the predetermined value H is 3, the first radio frequency test result is unqualified, then the second test is performed, and the second test result is qualified, then PASS is prompted to end the test . If the result of the second test is still unqualified, proceed to the third test, if the third test is still unqualified, and the number of unqualified times reaches the predetermined value H=3, it will prompt FALL and end the test. If the third test is passed, it will prompt PASS and end the test. Similarly, if the predetermined value is 4, and the previous three tests are all unqualified, the fourth test will continue, and if the result of the fourth test is still unqualified, FALL will be prompted to end the test. If the result of the fourth test is qualified, it will prompt PASS and end the test. and so on.

The present invention only needs to use the common mobile phone radio frequency testing equipment in the current market, and can easily realize network switching and various radio frequency tests.
