Method for raising terminal model identification accuracy of mobile terminal and apparatus thereof

Abstract

The invention provides a method for raising terminal model identification accuracy of a mobile terminal and an apparatus thereof. The method comprises the following steps: according to a communication ticket of the mobile terminal in a network in a predetermined time period, establishing a first corresponding relation table between a subscriber identity and an IMEI of the mobile terminal; according to a data communication ticket of the mobile terminal in a network in a predetermined time period, establishing a second corresponding relation table between the subscriber identity and a terminal model; associating corresponding relations with a same subscriber identity in the first corresponding relation table and the second corresponding relation table, generating a third corresponding relation table among the subscriber identity, a TAC and the terminal model; according to the third corresponding relation table, counting and obtaining a quantity distribution proportion of various terminal models corresponding to a same TAC, wherein, the quantity distribution proportion is taken as a credibility parameter of the TAC corresponding to various terminal models. According to the method and the apparatus in the invention, accuracy of terminal model identification of the mobile terminal in a present network can be raised, and a corresponding credibility parameter is given.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and a device for improving the accuracy of terminal model identification of a mobile terminal. Background technique [0002] At present, there are mobile terminals of various brands and models produced by regular manufacturers in the mobile communication network, and there are also a large number of counterfeit phones and black phones. These illegal mobile terminals usually steal International Mobile Equipment Identity numbers (IMEI, International Mobile Equipment Identity number) of legal terminals produced by other regular manufacturers. Moreover, various mobile terminals in the network are updated very quickly. Therefore, mobile terminals with the same device type approval number (TAC) in the live network usually have multiple corresponding terminal models. [0003] When a mobile terminal surfs the Internet and browses a WEB website, it is very necessary...

AI Technical Summary

Problems solved by technology

Since not all mobile terminals have visited the mobile Internet, the range of mobile terminals identified by this scheme is limited, and it cannot cover all or most of the mobile terminals in the live network.

Moreover, because there are a large number of counterfeit mobile phones and black mobile phones in the existing network, the UA format uploaded by these terminals is not standardized, and even the UA data may be untrue due to virus and other reasons. Therefore, if the terminal model is identified based on the UA data as the only standard, then The recognition accuracy is not high
