Some terms used in the embodiments of the present invention are explained below to facilitate understanding by those skilled in the art.

The base station in the present invention may also be a device for providing a terminal with a wireless communication function in other communication systems that may appear in the future. In the embodiments of the present invention, a "base station" is taken as an example for description.

3. ASN.1 (Abstract Syntax Notation One) is an ISO/ITU-T standard describing a data format for representing, encoding, transmitting and decoding data.

The network architecture and the service scenario described in the embodiment of the present invention are for more clearly illustrating the technical solution of the embodiment of the present invention, and do not form a limitation on the technical solution provided in the embodiment of the present invention, and it can be known by those skilled in the art that the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems along with the evolution of the network architecture and the appearance of a new service scenario.

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

At present, in an external field test scenario in the prior art, a method for acquiring a reference Signal to Noise Ratio (CSI-RS-SINR) corresponding to a base station in the prior art is shown in fig. 1, where fig. 1 is a method for acquiring a reference Signal to Noise Ratio in the prior art.

Step 101: and determining a downlink CSI-RS-SINR value through the obtained receiving power in the base station, and performing offline statistics on the determined downlink CSI-RS-SINR value to obtain a log.

Step 102: and checking the log offline.

Step 103: the terminal cannot display the downlink CSI-RS-SINR value in real time.

Step 104: and extracting logs in the last period of time from the base station, and screening out CSI-RS-SINR values from the logs.

Step 105: and carrying out manual off-line analysis on the screened CSI-RS-SINR values.

It can be seen that, in the prior art, when a downlink CSI-RS-SINR value is obtained, an internal log switch needs to be set inside the base station side in advance, so that the CSI-RS-SINR value of a time period can be uploaded, and then a related downlink CSI-RS-SINR value is extracted from a reported log, that is, the whole obtaining process is relatively long, and the CSI-RS-SINR value cannot be received in real time at the terminal side, which results in relatively low efficiency of obtaining the CSI-RS-SINR value. And when the corresponding downlink CSI-RS-SINR value is determined, the processing process is rough, the effect during testing cannot be accurately shown in real time, and therefore the accuracy of test data of subsequent external field test work is poor.

In view of this, the present invention provides a method for acquiring a signal-to-noise ratio of a reference signal, by which a downlink CSI-RS-SINR value can be quickly and accurately acquired at a terminal corresponding to a terminal side, thereby improving the efficiency of acquiring the CSI-RS-SINR value.

Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a schematic flowchart of a method for acquiring a signal-to-noise ratio of a reference signal implemented at a terminal according to an embodiment of the present invention.

Step 201: if the terminal is determined to be accessed to the corresponding base station, an interface for receiving a signal-to-noise ratio (CSI-RS-SINR) value of a downlink reference signal is set;

step 202: the method comprises the steps of obtaining first information which is sent by a base station and contains a downlink CSI-RS-SINR value through an interface, and obtaining a corresponding CSI-RS-SINR value according to the first information.

In the embodiment of the present invention, when it is determined that the terminal accesses the corresponding base station, a CSI-RS-SINR interface, that is, an interface for receiving a signal-to-noise ratio CSI-RS-SINR value of a downlink reference signal, may be developed and set in drive test software installed in the terminal. Then, first information containing a downlink CSI-RS-SINR value sent by the base station can be obtained through the interface, and a corresponding CSI-RS-SINR value is obtained according to the first information.

In the embodiment of the present invention, the manner of acquiring the first information including the downlink CSI-RS-SINR value sent by the base station through the interface may be to acquire the first information according to configuration information agreed in advance with the base station; the first information may also be obtained correspondingly through the received second information, and certainly, the first information may also be obtained directly in real time, which is not limited in the embodiment of the present invention.

Optionally, the second information sent by the base station may be obtained through the interface, where the second information includes an issuing cycle and an issuing number of times for issuing the first information. And then acquiring first information containing the downlink CSI-RS-SINR value according to the second information through an interface. That is to say, in the embodiment of the present invention, on the basis of setting the interface, the downlink CSI-RS-SINR value can be timely and accurately obtained through the second information that is sent by the base station and includes the issuing period and the issuing frequency of the first information, so as to improve the efficiency of obtaining the downlink CSI-RS-SINR value.

In a specific implementation process, the base station may issue the second information before sending the first information to the terminal, and the terminal may determine the corresponding issue time based on the number of issues in the second information and an issue period, where the issue period may be, for example, 20ms, 40ms, 80ms, and the like, so that the first information including the downlink CSI-RS-SINR value may be obtained through the interface at the issue time, and the corresponding CSI-RS-SINR value may be obtained.

Optionally, the configuration information agreed in advance with the base station may also be determined, where the configuration information includes an issuing cycle and an issuing number of times for issuing the first information including the downlink CSI-RS-SINR value, and then the first information may be acquired through the interface according to the configuration information. That is to say, the terminal may directly obtain the first information including the downlink CSI-RS-SINR value through the interface at the corresponding issuing time according to the pre-agreed configuration information, and simply and quickly obtain the downlink CSI-RS-SINR value.

In the embodiment of the present invention, after the first information is obtained, a downlink CSI-RS-SINR value may also be correspondingly received in each period of the downlink period, and then an average value is determined according to a plurality of downlink CSI-RS-SINR values received in a corresponding monitoring period, so that a corresponding CSI-RS-SINR value may be determined according to the average value. In such a way, the statistical analysis can be carried out on the obtained CSI-RS-SINR value more accurately.

Further, aiming at the problem that the downlink CSI-RS-SINR value in the prior art cannot be displayed, in the embodiment of the present invention, the average value and the corresponding period may also be stored, and then the average value and the corresponding period are encoded according to a preset encoding method and displayed on a display interface for output.

In a specific implementation process, a downlink CSI-RS-SINR value issued in real time is acquired from a base station according to an issuing period such as 20ms, 40ms, 80ms and the like in a message issued from the base station, and after a terminal installed with drive test software acquires original data, namely the downlink CSI-RS-SINR value issued in real time by the base station, the downlink CSI-RS-SINR value issued in real time is encoded through an asn.1 and can be displayed in a related interface corresponding to the drive test software in a cstring data type manner, specifically, the related interface is a display interface corresponding to an interface, so that the downlink CSI-RS-SINR value can be clearly displayed at a terminal side. In addition, sampling points of mean value, maximum value and minimum value can be set by taking different time as a unit, data of a specific downlink CSI-RS-SINR value of a certain terminal is counted off line, and a distribution diagram is drawn, so that the downlink CSI-RS-SINR value can be determined more accurately and clearly.

In the embodiment of the invention, the drive test software can acquire the CSI-RS-SINR data measured by the current base station through the set interface. And then, the drive test software calculates the average value of the CSI-RS-SINR data acquired in the monitoring period in each monitoring period, and records the CSI-RS-SINR average value and the starting time of the monitoring period in a local CSI-RS-SINR diary correspondingly. Further, the drive test software may perform statistics on at least one CSI-RS-SINR average value acquired in a statistical period, where the statistical period includes at least one monitoring period, so that a current downlink CSI-RS-SINR value may be obtained according to a statistical result. Namely, the embodiment of the invention can quickly and accurately acquire the CSI-RS-SINR value and can acquire the CSI-RS-SINR data measured by the base station at the terminal side in real time, thereby more intuitively observing the range of the downlink quality index and improving the test efficiency of the external field test.

Fig. 3 exemplarily shows a flowchart of a method for acquiring a reference signal to noise ratio implemented at a base station side according to an embodiment of the present invention, and as shown in fig. 3, the flowchart may include:

step 301: determining a preset issuing period and issuing times, and determining issuing time according to the preset issuing period and issuing times;

step 302: and at the downlink time, first information containing a downlink reference signal-to-noise ratio (CSI-RS-SINR) value is sent to a terminal corresponding to the base station, so that the terminal can obtain the corresponding CSI-RS-SINR value.

In the embodiment of the present invention, the base station may determine the preset issuing period and issuing times, specifically, may acquire configuration information agreed in advance with the terminal, where the configuration information includes the issuing period and issuing times for issuing the first information, so as to determine the preset issuing period and issuing times. Of course, the base station may also determine a preset issuing period and issuing times according to actual conditions.

Further, after the preset issuing period and the issuing times are determined, a timer for configuring the reference signal to noise ratio CSI-RS-SINR can be set according to the issuing period and the issuing times, the issuing time is determined according to the timer, and then first information containing the downlink reference signal to noise ratio CSI-RS-SINR value can be sent to the terminal corresponding to the base station at the issuing time, so that the terminal can obtain the corresponding CSI-RS-SINR value.

Optionally, in the embodiment of the present invention, after the base station determines the preset delivery cycle and delivery times according to an actual situation, the base station may deliver the second information to the terminal, where the second information includes the delivery cycle and delivery times for delivering the first information, so that the terminal may obtain the first information including the downlink CSI-RS-SINR value delivered by the base station.
