s200, searching parameters corresponding to the parameter identifications from the network parameters according to the parameter identifications;
the parameter checking rule may further include information such as a parameter category, a parameter name, and a function meaning. In practice, after the network optimization platform obtains the network parameters, each parameter is identified, and the identification is unique, and since the obtained network parameters come from different manufacturer devices and different manufacturers may use different names for the same parameter, the identification is used for uniquely identifying the parameter.
S210, reading the priority level in the parameter checking rule;
s220, checking and configuring the parameters according to the recommended levels and the parameter suggested values corresponding to the recommended levels; or, according to the reference level and the parameter value range corresponding to the reference level, checking and configuring the parameter.
Specifically, when the priority level is a recommended level, determining whether the value of the parameter corresponding to the parameter identifier is the same as the suggested value of the parameter, if not, modifying the parameter value corresponding to the parameter identifier to the suggested value of the parameter, and if so, keeping the parameter value corresponding to the parameter identifier;
when the parameter level is a reference level, judging whether the parameter value corresponding to the parameter identification is in the parameter value range; if so, reserving a parameter value corresponding to the parameter identifier; if not, the parameter value corresponding to the parameter identification is modified into the parameter suggestion value.

In practice, considering that different vendors may set different data types for the same network parameter, the checking rule for the same parameter should include checking for different data types, where the different data types are shown in the following table:
for the parameters: initially receiving the target power, the device of the chinese style sets the parameter value by using the data type as an enumeration type, that is, different parameter values are identified by using 0 to 15 enumeration values, so the parameter value needs to be set by using the enumeration type when setting the parameter check rule, and the device of the chinese style sets the parameter value by using the data type as the data value, so the parameter value needs to be set by using a numerical type when setting the parameter check rule.
In view of this, in the parameter checking rule according to another embodiment of the present application, one parameter identifier corresponds to a parameter value range and a parameter suggested value of two data types, that is, the parameter checking rule includes checking rules for different data types of the same parameter for different factory devices.
The specific parameter checking rule is as follows: according to the parameter identification, the first data type parameter value range, the first data type parameter suggestion value, the second data type parameter value range and the second data type parameter suggestion value, a parameter checking rule is set by combining a parameter priority level, wherein the priority level comprises a recommendation level and a reference level;
then, according to the parameter checking rule set, the method for checking the network parameter corresponding to the current cell includes:
s300, searching parameters corresponding to the parameter identifications from the network parameters according to the parameter identifications;
s310, determining the device identifier which is the same as the device identifier corresponding to the network parameter in the first device identifier and the second device identifier;
the step may be performed before step S300. And the manufacturer equipment corresponding to the first data type and the second data type is respectively represented by the first equipment identification and the second equipment identification, and the specific checking and configuration is determined to be carried out on the first data type or the second data type in the checking rule by judging which of the first equipment identification and the second equipment identification is the same as the equipment identification corresponding to the network parameter.
S320, reading the priority level in the parameter checking rule;
s330, checking and configuring the parameters according to the recommended levels and the parameter suggested values corresponding to the equipment identifiers which are the same as the equipment identifiers corresponding to the network parameters; or, according to the recommended level and the parameter value range corresponding to the device identifier which is the same as the device identifier corresponding to the network parameter, checking and configuring the parameter.
Specifically, when the first device identifier is the same as the device identifier corresponding to the network parameter: if the priority level is a recommendation level, judging whether the value of the parameter corresponding to the parameter identifier is the same as the suggested value of the first data type parameter, if not, modifying the parameter value corresponding to the parameter identifier into the suggested value of the first data type parameter, and if so, keeping the parameter value corresponding to the parameter identifier;
if the parameter level is a reference level, judging whether the parameter value corresponding to the parameter identification is in a first data type parameter value range; if so, reserving a parameter value corresponding to the parameter identifier; if not, the parameter value corresponding to the parameter identification is modified into a first data type parameter suggestion value.
When the second device identifier is the same as the device identifier corresponding to the network parameter, the principle of the checking and configuring process is the same as the checking and configuring process when the first device identifier is the same as the device identifier corresponding to the network parameter, which is not described herein again.
It will be appreciated that when there are three data types for the same parameter, the checking can be performed using the principle of implementation of the parameter checking rule as described above.
The parameter checking in the above embodiment includes checking rules of the device parameters of different manufacturers, that is, the checking rules are compatible with checking of the parameters of different data types, so as to avoid a second process performed on the network parameters in the prior art, where the second process is to process the network parameters into standard data types according to a certain rule after the network parameters are obtained.
The checking rule may further include a checking rule of multi-parameter operation, that is, the checking rule includes a parameter operation formula, and when checking, the relevant network parameters related to the formula are obtained, and then the relevant network parameters are operated according to the formula, and whether the operation result meets the checking rule is determined, for example: and if the formula in the checking rule is a + b > c, acquiring related network parameters a and b, judging whether the network parameters a and b are greater than the value c after being added, if so, meeting the checking rule, if not, and recording the checking of the network parameters which do not meet the checking rule. The parameter checking rule can also comprise a setting rule of various granularity parameters: for example, switching hysteresis thresholds are set for different measurement times of an A1 event, an A2 event, a B1 event, a B2 event and the like, so that the network parameters of each granularity are guaranteed to be checked through parameter checking rules.
In another embodiment of the present application, the method for determining the geographical scenario in which the current cell is located according to the geographical scenario information specifically includes:
1) determining the land feature information of the cell according to the land feature of the geographic range covered by the cell and a preset rule;

Wherein the height or floor information of the house may be acquired after determining whether the category information is the residential area, so as to determine whether the category information of the feature is the general residence or the high-rise residence.
Then, the feature information of the current cell is determined, and the feature information may only include the position information and the category information in the feature information.
Wherein, the preset rule is that when there is a type of ground object in the geographic coverage of the current cell, the ground object information of the type of ground object is used as the ground object information of the current cell, for example; the method comprises the steps that only one building of a stadium is arranged in a geographic range covered by a current cell, the type of a ground object is the stadium, and the ground object information of the cell is determined to comprise large-scale stadium type information and position information of the stadium;
as another example, there are a plurality of buildings within the coverage area of the current cell, but the categories of these features are shopping centers, that is, features belonging to the same category, so it can be determined that the feature information of the cell includes shopping center-to-feature category information and urban area location information.
