Abstract
The present invention discloses a method of measuring the dispersion degree of the radiating of MAT which includes RUT and RNUT both of which can work in the first frequency band and the second frequency band. The frequency band of RUT and RNUT has many combinations, and each frequency band corresponds to certain of channels. The method includes the steps of: step 1, establishing a testing environment with a plurality of wireless links of MAT; step 2, a plurality of channels are positioned in the first frequency band and the second frequency band; step 3, measuring the dispersion degree of the radiating of MAT in each channel combination under each frequency band combination of RUT and RNUT; step 4, judging that if each dispersion of the radiating being measured is beyond the preset value, if it is not, the testing is ended, while if it is, the transmitting powder of MAT is reduced, then the step 3 will be repeated to obtain a new group of dispersions of the radiating; if each of the new dispersion of the radiating is not beyond the preset value, the testing is ended, while if one of the dispersions of the radiating is beyond the preset value, the test is failed. The testing result in the present invention reflects the radio interference resisting ability more veritably.
Description
Technical field
The present invention relates to a kind of portable terminal measurement method of parameters, relate in particular to a kind of a plurality of radio insert portable terminal (hereinafter to be referred as multi-access terminal, Multi-Access Terminal, MAT) measuring method of radiation dispersion.
Background technology
The development of current mobile communication technology has presented flourishing scene; various new technologies emerge in an endless stream; such as: second generation mobile communication technology is just progressively to the third generation mobile technical development at present; the increasing demand of people has also stimulated the appearance of new technology simultaneously; this wherein; 2G, the network of different systems such as 3G will and be deposited in very long a period of time, so the appearance of bimodulus or multi mode terminal will become the inevitable choice of market transition period.The appearance of bimodulus or multi mode terminal has reduced the cost of operator effectively; farthest kept the existing customer resources of operator, the target of the smooth evolution of a plurality of mobile networks' of operator fusion simultaneously and business more makes bimodulus or multi mode terminal become the main flow of current Communications Market.Occurred at present such as: GSM/PHS double model double standby phone, GSM/GSM double model double standby phone, GSM/TD-SCDMA double model double standby phone etc., the common feature of these terminals is that a portable terminal can be operated under the network of two or more standards.
Yet, multiple access module, the appearance of multiple standby mode terminal, a difficult problem that radio frequency phase mutual interference between the different systems frequency range occurred, such as the GSM/GSM mobile phone, the working frequency range of GSM standard is 900MHZ and 1800MHZ, and two number whiles, the frequency of work will produce the problem of radio frequency phase mutual interference when carrying out communication traffic.Be operated in a certain frequency of 900MHZ frequency range such as a number, another number is operated in a certain frequency of 1800MHZ frequency range, two frequencies will produce Radio frequency interference (RFI) mutually, Radio frequency interference (RFI) has seriously influenced the normal use of MAT, so the anti-Radio frequency interference (RFI) performance of MAT just becomes very one of important index of measurement MAT performance.Radiation dispersion then is an important indicator weighing bimodulus or multimode communicating terminal Radio frequency interference (RFI) performance, and is common by the ability whether portable terminal possesses good anti-Radio frequency interference (RFI) is weighed in the measurement of radiation dispersion in the reality.
And at present in the radiation dispersion test process of MAT, all not have consideration in the practical application scene non-radio to be measured (Radio Not Under Test hereinafter to be referred as: RNUT) (RadioUnder Test is hereinafter to be referred as influence RUT) to radio to be measured.And RNUT is coloured interference of an anisotropic for RUT, and the existence of RNUT has obvious difference when causing the radiation dispersion of RUT to compare the RUT individualism.If so do not consider the existence of RNUT factor, the radiation dispersion when only testing the RUT individualism, the result who draws just can not truly reflect the real ability of the anti-Radio frequency interference (RFI) of portable terminal.
So, consider the influence of RNUT, need be the coloured noise source of RUT with the RNUT equivalence, and then under described coloured noise environment, the radiation dispersion of MAT be measured.
Summary of the invention
At the problem that exists in the above-mentioned actual test, the invention provides a kind of method of testing of MAT radiation dispersion of the RNUT of consideration influence factor.By using this method, when having solved present test MAT radiation dispersion, do not consider the problem of RNUT influence factor, make the result who tests out reflect the anti-Radio frequency interference (RFI) ability of MAT more really.
For addressing the above problem, the invention provides following technical scheme:
A kind of measuring method of MAT radiation dispersion, it is characterized in that, this MAT comprises radio terminal RUT to be measured and non-radio terminal RNUT to be measured, RUT and RNUT all can work in first frequency range and second frequency range, the working frequency range of RUT and RNUT has multiple combination, the corresponding some channels of each frequency range, this method may further comprise the steps:
Step 1 is set up a plurality of Radio Link test environments of MAT;
Step 2 is provided with a plurality of channels respectively in first frequency range and second frequency range;
Step 3, the radiation dispersion of the MAT of measure R NT and RNUT each the channel combination under each working frequency range combination;
Step 4, judge whether each radiation dispersion of surveying exceeds preset value, if all do not exceed preset value, then end of test (EOT), if there is one to exceed preset value, then reduce MAT emissive power (back-off), repeated execution of steps 3 obtains one group of new radiation dispersion, if this new radiation dispersion does not all exceed preset value, end of test (EOT) then is if there is one to exceed preset value, then test crash.
Further, further comprise before the described step 3: adjusting the MAT emissive power is maximal value.
Further, a plurality of channels in the described step 2 comprise a low frequency channel, an intermediate-frequency channel and a high frequency channel.
Further, the combination of the working frequency range in the described step 3 comprises following four kinds of situations:
