For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing the embodiments of the present invention are explained in detail.Yet, persons of ordinary skill in the art may appreciate that in each execution mode of the present invention, in order to make the reader understand the application better many ins and outs have been proposed.But, even without these ins and outs with based on many variations and the modification of following each execution mode, also can realize each claim of the application technical scheme required for protection.
The first execution mode of the present invention relates to a kind of control method of terminal reception antenna, and the method is the index of the expression signal receiving quality of each reception antenna of measuring terminals at first; After measuring each time, whether according to the desired value that measures, it is reliable to detect the corresponding reception antenna of this desired value, then when the reception antenna of terminal is controlled fast, according to the fast measured value of control that is used for of reliable reception antenna, control fast; Wherein, index is measured as periodic measurement.The below has two reception antennas take terminal and is specifically described as example.
As shown in Figure 2, the index of the expression signal receiving quality of each reception antenna of measuring terminals at first, i.e. execution in step S201 measures the index of the expression signal receiving quality of two reception antennas.
Since when the data of part reception antenna become insincere after, the measured values such as Reference Signal Received Power RSRP or noise power institute is influenced to be not very large, so use the measured value of RSRP or the measured value of signal to noise ratio snr can judge reliably the reliable antenna of receive data.Therefore, in the present embodiment, the index of expression signal receiving quality is signal to noise ratio snr or Reference Signal Received Power RSRP.
Then, whether according to the desired value that measures, it is reliable to detect the corresponding reception antenna of this desired value in step S202 to S204.
Specifically, in step S202, the difference of the desired value of two reception antennas measuring and default the first thresholding are compared, judge that namely whether the difference of desired value of two reception antennas that measure is greater than the first default thresholding; Wherein the concrete numerical value of the first thresholding can be an empirical value, obtain according to experiment simulation, such as, a plurality of numerical value are set to be tested respectively as the first thresholding, determine the concrete value of the first thresholding according to experimental result, according to Simulation results, the first thresholding can guarantee receptivity greater than 3dB usually, and the concrete value of the first thresholding is not done restriction at this.
If difference is greater than the first thresholding, then execution in step S203 judges that the reception antenna that desired value is less is unreliable in two reception antennas, and the reception antenna that desired value is larger is reliable;
If difference is less than or equal to the first thresholding, then execution in step 204, judge that two reception antennas are all reliable.
Such as, the index of expression signal receiving quality is RSRP, and two reception antennas that terminal comprises are respectively reception antenna 1 and reception antenna 2, and the RSRP value of the reception antenna 1 that measures is R1, the RSRP value of the reception antenna 2 that measures is R2, and the first default thresholding is T1.So, in step S202, can be according to formula | R1-R2|＞T1 judges that whether the difference of desired value of two reception antennas is greater than the first thresholding, if greater than T1, then enter step S203, judge that among R1 and the R2, the larger corresponding reception antenna of a RSRP value (such as R2) (such as reception antenna 2) is reliable; If be less than or equal to T1, then enter step S204, judge that reception antenna 1 and reception antenna 2 are all reliable.
