With the impact of Internet business and implementation of national policies such as "speed up and fee reduction" and "number portability"

operators generally face problems like slowing business growth

decline of unit netflow

enhancement of user demand individuation

etc.As the provider of basic communication service

operator has natural data advantages.Therefore

how to use massive big data to explore potential users has become one of the focus of precision marketing and business transformation.In this paper

we establish a comprehensive location information database which contains the names and labels of various scenarios based on big data like XDR

MDT

API interface data.Furthermore

combining the above location information database with economic analysis data like ARPU and DOU

we can obtain merging data including user basic information

time stamp

latitude and longitude

scene label

user traffic characteristics

etc.Based the above merging data

we further propose a method of excavating potential users and discerning possible lost users which could provide references of achieving refined marketing.
