MAC (media Access Control Address) address, translated as MAC address. It is an address used to identify the location of network devices, and MAC addresses are unique throughout the world as long as their MAC addresses are not changed. The MAC address is, in a descriptive sense, just like the identification card number on the identification card, and has uniqueness. Therefore, it is a new attempt in the industry to apply the MAC address of the terminal device to the model identification operation.
On the basis, a new terminal signal identification scheme appears in the industry, namely, the identified mac is used as a basic library, and the actual model is calculated according to the distance between the mac to be inquired and the basic library.

Detailed Description
The invention discloses a method, a device, a terminal and a storage medium for dynamically identifying a terminal model based on an MAC address.
In one aspect, the invention relates to a terminal model dynamic identification method based on MAC address, comprising:
s1, classifying and ordering the identified MAC sections, dynamically aggregating the MAC sections, counting the ratio of each terminal signal in the process, and comparing the ratio result with a preset threshold value to obtain a dynamic MAC section library, wherein the dynamic MAC section library contains dynamic relations between MAC sections with different lengths and terminal models. As shown in fig. 1, this step specifically includes.
S11, using the recorded and identified MAC segments as initial data, including known information as much as possible, dividing all the MAC segments into several groups based on OUI (organization unique identifier), where there are multiple MAC segments under the same OUI, and different OUI have no relationship or influence each other.
The following two parameters need to be set subsequently.
The length range of the MAC segment, i.e., n, cannot be less than 6 bits at the shortest, the first 6 bits of the MAC segment are assigned to the relevant vendor by IEEE, and less than the first 6 bits makes no sense. The longest length is 11 bits, because the total length of the MAC section is 12 bits, if the longest length is 12 bits, the known data is the one-to-one correspondence relationship between the MAC section and the identification result, and the purpose of cleaning up dirty data cannot be achieved.
The occupation ratio threshold value of the device model in the MAC segment, that is, P, is that when the occupation ratio of a certain device model in the MAC segment reaches the threshold value, the identification result may represent all the identification results of the MAC segment under the MAC segment, and the value should be at least greater than 50%, so as to ensure that each MAC segment corresponds to only one model.
And S12, dynamically aggregating from the first n bits of the MAC section. And starting aggregation from the first 6 bits of the set shortest length, counting the ratio of each terminal model in the aggregation process, comparing the ratio result with a preset threshold value P, and if the ratio reaches the preset threshold value P, outputting the dynamic relationship between the MAC sections with different lengths and the terminal models and taking the dynamic relationship as a dynamic MAC section library. If the identification precision is desired to be improved, the default length start bit of the MAC segment can be appropriately increased, but correspondingly, the coverage area is smaller, and the number of the finally generated corresponding relationship files is increased.
And if the occupation ratio is not less than the preset threshold value P, adding an operation to the execution length of the MAC section and repeating the process until the MAC section reaches the maximum length or cannot be aggregated, and if the occupation ratio is always less than the preset threshold value P, discarding the MAC section and effectively cleaning dirty data.
An actual operation flow is provided below to verify the above scheme.
(1) Setting a starting parameter, n: n is more than or equal to 6 and less than or equal to 11, P: 95 percent.
(2) The MAC segment whose specific model has been identified by other methods is selected, here OUI "E86819" is taken as an example. A total of 73420 MAC segments are known under this OUI with a total of 98 terminal models.
(3) The MAC segment is defaulted to 6-11 bits, the former 6 bits are aggregated, and the occupation ratio of each model after aggregation is judged. At the moment, the maximum of the model accounts for 46 percent, the maximum of the model accounts for 95 percent, the MAC segment length is added with 1, and the MAC segment length is re-aggregated.
(4) And if the previous 7 bits are aggregated, 16 groups of data exist from 0 to F, the statistical percentage of each group is larger than 95%, the data are output to a final dynamic library file, if the data are aggregated to a certain bit, only one MAC section is identified or the data are aggregated to 11 bits, the identification result is still very disordered, the MAC section is discarded if the percentage of any type can reach a preset threshold value, and the like.
(5) Eventually this OUI co-forms a 7-segment MAC segment with the following results.

S2, loading the dynamic MAC segment library, matching the input MAC address with the dynamic MAC segment library, if the matching is successful, outputting the corresponding terminal model, otherwise, outputting the MAC address without identification. As shown in fig. 2, this step specifically includes.
S21, after the configuration of the starting parameters is completed, the dynamic MAC segment library is started and loaded, the MAC signal query interface is opened, and the input MAC address to be queried is acquired through the MAC signal query interface. The starting parameters include n and P as described above.
And S22, matching the MAC section bit number range appointed by the starting parameter with the dynamic MAC section library from small to large, outputting a corresponding terminal model if the matching is successful, and outputting the MAC address not to be identified if the matching is not successful until the maximum length of the MAC section.
An actual operation flow is provided below to verify the above scheme.
(1) Assume that the list of MAC addresses currently to be queried is as follows: e868193CA5E0, E8681928C7DC, E8681906616E, 000763FAB 39A.
(2) Starting service, loading the generated dynamic MAC segment library, setting starting parameters, and n: n is more than or equal to 6 and less than or equal to 11.
(3) The MAC addresses to be inquired are input one by one, the values set by the starting parameters are intercepted from small to large and are matched with the dynamic MAC segment library, and the final result is as follows.
