Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present application based on the embodiments herein.
Fig. 1 is a flow chart of a method for adjusting downlink rate according to an embodiment of the present application, as shown in fig. 1, where the steps of the method include:
the received power may refer to RSRP (Reference Signal Receiving Power, reference signal received power), that is, RSRP corresponding to the radio frequency main set and the radio frequency diversity. Furthermore, the difference in received power indicates that the network environment in which the terminal is located is different. Taking the received power as RSRP as an example, the initial RSRP of the radio frequency main set is-85 dbm and the initial RSRP of the radio frequency diversity is-91 dbm in a certain network environment. The initial RSRP of the radio frequency main set of the same terminal under another network environment is-96 dbm, and the initial RSRP of the radio frequency diversity is-90 dbm.
in this embodiment of the present application, the target received power is the received power of the main radio frequency set when the terminal maintains the initial received power of the radio frequency diversity unchanged under the initial condition of the initial received power, adjusts the received power of the main radio frequency set, and obtains the maximum signal-to-noise ratio. The target received power may also be an empirical value in other examples. Taking the received power as RSRP as an example, in general, the larger the value of the SINR (Signal to Interference plus Noise Ratio, signal-to-interference-plus-noise ratio), the higher the downlink rate is, so in the embodiment of the present application, the value of the SINR is adjusted by adjusting the RSRP of the radio frequency main set, so that the adjustment of the downlink rate can be achieved.
Through the steps 101 to 103, the received power corresponding to the main radio frequency set and the received power corresponding to the diversity radio frequency set on the terminal are obtained in the current network environment, and are matched with metadata in a metadata base, if a group of initial received powers which are the same as the current received power exist in the metadata base, the first received power is set as a target received power corresponding to the initial received power; that is, if the first receiving power of the main radio frequency set is matched, the first receiving power of the main radio frequency set can be set as the target receiving power to increase the downlink rate, and compared with the mode that the layout density of the base station is increased or the transmitting power of a single base station is increased to increase the downlink rate in the related art, the mode in the application has higher operability, lower cost and large signal strength adjusting range.
In an optional implementation manner of the embodiment of the present application, the method of the embodiment of the present application may further include:
104, if the metadata database does not have a group of initial received powers which are the same as the current received power, keeping the second received power unchanged, and adjusting the first received power to be the preset first received power at least once according to a preset strategy;
step 105, recording a preset first receiving power and a corresponding signal to noise ratio, and setting the first receiving power as the preset first receiving power corresponding to the maximum signal to noise ratio in the plurality of signal to noise ratios.
It can be seen that, in the implementation of the present application, if there is no set of initial received powers that are the same as the current received power in the current metadata base, a preset strategy is required to adjust the first received power at least once, where the preset strategy may refer to that the first received power is adjusted by a certain fixed value, for example, 0.2dbm,0.3dbm, etc. are added each time, or 0.2dbm,0.3dbm, etc. are subtracted each time, and specific fixed values may be set correspondingly according to actual requirements, where the signal-to-noise ratio corresponding to each adjustment of the received power changes correspondingly, and the greater the signal-to-noise ratio is, the higher the downlink rate is, so that the first received power is set from the adjustment process to the preset first received power corresponding to the maximum signal-to-noise ratio in multiple signal-noise ratios, and the corresponding downlink rate is also optimal.
In an optional implementation manner of the embodiment of the present application, for adjusting the first received power at least once according to the preset policy, which is referred to in step 104 above, to the preset first received power may further be: and adjusting the first receiving power to preset first receiving power, wherein the difference value between the preset first receiving power and the second receiving power is smaller than a first preset threshold value.
It should be noted that, in the present application, when the difference of the primary diversity reception power is smaller, the received signal is stronger, that is, the signal-to-noise ratio is higher. Therefore, in the embodiment of the present application, it is preferable to directly adjust the first received power to a preset first received power, and the difference between the preset first received power and the second received power is smaller than a first preset threshold, where the first preset threshold may be set correspondingly according to practical situations, for example, the first preset threshold is 0.3dbm,0.4dbm, and so on, so as to ensure that the adjusted first received power and the adjusted second received power are as close as possible, so as to improve the downlink rate.
In an optional implementation manner of this embodiment of the present application, for the recording preset first received power and the signal to noise ratio corresponding to the recording preset first received power related to the step 105, the setting the first received power to the preset first received power corresponding to the maximum signal to noise ratio in the multiple signal to noise ratios may further be: and recording different preset first receiving powers and the values of signal to noise ratios thereof in the first receiving power adjustment process, and setting the first receiving power as the preset first receiving power corresponding to the maximum signal to noise ratio in the signal to noise ratios.
Therefore, the signal to noise ratio corresponding to each adjustment of the first received power will change correspondingly, so that the first received power corresponding to the maximum signal to noise ratio can be selected from the recorded signal to noise ratios to obtain the optimal downlink rate.
In an optional implementation manner of this embodiment of the present application, for the manner of adjusting the first received power to the preset first received power at least once according to the preset policy in step 104, further may be: acquiring a first difference value of the first received power and the second received power, and setting a group of first received power adjustment values according to the fixed difference value in a first difference value range so that the first received power acquires a corresponding group of preset first received power according to the adjustment values;
in this regard, the fixed difference may be 1dbm,2dbm,3dbm, etc. in a specific example, and the fixed difference may be specifically set according to actual requirements. That is, in the embodiment of the present application, the first received power is regularly adjusted based on the fixed difference, so that a set of preset first received powers obtained after multiple adjustments in the adjustment process can be obtained.
In an optional implementation manner of this embodiment of the present application, for the recording preset first received power and the signal to noise ratio corresponding to the recording preset first received power related to the step 105, the setting the first received power to the preset first received power corresponding to the maximum signal to noise ratio in the multiple signal to noise ratios may further be: and recording different preset first receiving powers and the values of signal to noise ratios thereof in the first receiving power adjustment process, and setting the first receiving power as the preset first receiving power corresponding to the maximum signal to noise ratio in the signal to noise ratios.
Therefore, the signal to noise ratio corresponding to each adjustment of the first received power will change correspondingly, so that the first received power corresponding to the maximum signal to noise ratio can be selected from the recorded signal to noise ratios to obtain the optimal downlink rate.
In an optional implementation manner of the embodiment of the present application, after setting the first received power to a preset first received power corresponding to a maximum signal-to-noise ratio of the multiple signal-to-noise ratios, the method of the embodiment of the present application may further include:
step 106, storing the first received power, the second received power and the preset first received power corresponding to the maximum signal to noise ratio as a set of new metadata in a metadata base;
the first receiving power and the second receiving power are used as the initial receiving power of the radio frequency main set and the initial receiving power of the radio frequency diversity to be stored; and saving the preset first receiving power corresponding to the maximum signal-to-noise ratio as target receiving power corresponding to the initial receiving power.
It can be seen that, in this embodiment of the present application, after determining the preset first receiving power corresponding to the maximum signal-to-noise ratio based on the first receiving power and the second receiving power, the preset first receiving power may be stored in the metadata base to update the data in the metadata base, and if the receiving power of the current terminal is still the first receiving power and the second receiving power, the corresponding preset first receiving power may be directly matched from the metadata base at the next time, and then the first receiving power is set as the target receiving power corresponding to the initial receiving power.
In an optional implementation manner of the embodiment of the present application, in the case that the number of radio frequency diversity is N, the initial received power in each set of metadata includes an initial received power of one radio frequency main set and N initial received powers of radio frequency diversity, and one target received power corresponding to the initial received powers, where N is an integer greater than 1;
based on this, for the manner of determining whether there is a set of initial received powers in the metadata base that are the same as the current received power referred to in 102 in the embodiment of the present application, it may further be: it is determined whether there is a one-to-one match of the initial received power of the N radio frequency diversity in the set of metadata with the N second received powers in the metadata, and the first received power matches the initial received power of the main set of radio frequencies in the set of metadata.
It can be seen that the received power of the rf main set and the received power of the diversity in the embodiment of the present application need to be matched with a set of metadata in the metadata database at the same time, that is, when the received power of the current terminal is compared with the metadata in the metadata database, the received power of the rf main diversity needs to be compared with the rf main set initial received power and the rf diversity initial received power of a set of metadata in the metadata database. Taking N as 3 as an example, it is required to determine whether there is a one-to-one match between the initial received power of the 3 radio frequency diversity in the set of metadata and the 3 second received powers, and a match between the initial received power of the radio frequency main set in the set of metadata and the first received power. Because in some cases there may be one or more radio frequency diversity of the terminal; based on this, in the metadata base in the embodiment of the present application, not only the received powers with the number of the main radio frequency diversity being 1, but also the received powers with the number of the main radio frequency diversity being 1 and the radio frequency diversity being multiple are stored, so as to ensure that when matching is performed, the appropriate target power can be determined.
Further, in the embodiment of the present application, for the manner that the above-mentioned determination metadata includes matching the initial received powers of the N radio frequency diversity in the set of metadata with the N second received powers in a one-to-one correspondence manner, and the matching of the first received power with the initial received power of the radio frequency main set in the set of metadata may further include:
step 11, determining whether the difference value between the first received power and the initial received power of the radio frequency main set in the group of metadata is smaller than a second preset threshold value, and determining whether the difference value between the second received power and the initial received power of the radio frequency diversity in the corresponding metadata is smaller than a third preset threshold value; the N second receiving powers are in one-to-one correspondence with the N initial receiving powers of the radio frequency diversity.
The metadata base in the embodiment of the present application includes a plurality of metadata sets in different network environments, because the initial received powers of the radio frequency main set and the radio frequency diversity of the terminal in different network environments are not identical, taking the received power as RSRP as an example, for example, the initial RSRP of the radio frequency main set of the terminal in a certain network environment is-85 dbm, and the initial RSRP of the radio frequency diversity is-91 dbm; in another network environment, the initial RSRP of the radio frequency main set of the same terminal is-96 dbm, and the initial RSRP of the radio frequency diversity is-90 dbm. That is, in the embodiment of the present application, the received power of the rf main set is close to the initial received power of the rf main set in a certain group of metadata in the metadata base, and the received power of the rf diversity is close to the initial received power of the rf diversity in a certain group of metadata base, which indicates that the current network environment where the terminal is located is equivalent to the received power corresponding to the certain network environment stored in the metadata base, if the initial RSRP of the rf main set of the terminal in the current network environment is-84.6 dmb, the initial RSRP of the rf diversity of the terminal is-91.3 dbm, and the second preset threshold and the third preset threshold are both 0.5, then the condition is satisfied in the metadata base that the initial received power of the rf main set is-85 dbm, and the initial received power of the rf diversity is-91 dbm, and then the target received power of the rf main set in the group of metadata base is used as the target to be adjusted for the received power of the current rf main set. Therefore, the method and the device can be used for adjusting the receiving power of the radio frequency main set based on the metadata in the metadata base so as to improve the downlink rate, and the method for improving the downlink rate in the embodiment of the application is more flexible than the method in the prior art.
It should be noted that, in the embodiment of the present application, the second preset threshold and the third preset threshold may be set correspondingly according to actual requirements, for example, 0.5dbm,1dbm,2dbm, and so on.
In an optional implementation manner of the embodiment of the present application, before determining whether the target received power corresponding to the second received power in the current network environment exists in the metadata database, the method of the embodiment of the present application may further include:
step 21, determining whether the difference between the first received power and the second received power is greater than or equal to a fourth preset threshold;
step 22, in the case that the difference between the first received power and the second received power is greater than or equal to the fourth preset threshold, an operation of determining whether the target received power corresponding to the second received power in the current network environment exists in the metadata base is performed.
Based on the above steps 21 and 22, it can be known that if the current first received power and the second received power are smaller than the fourth preset threshold, the operation of determining whether the target received power corresponding to the second received power in the current network environment exists in the metadata base is not needed, because the difference between the first received power and the second received power is smaller, it is indicated that the value of the signal-to-noise ratio is larger at this time, and the current downlink rate is higher and no adjustment is needed. If the difference value of the expression and the expression is larger, the current signal-to-noise ratio of the expression is smaller, and the downlink rate is lower, so that the expression and the expression are required to be further compared with metadata in a cloud database to determine to adjust the first receiving power so as to improve the downlink rate.
