Method for finding out network edge roaming problem through call bill depth excavation

Abstract

The invention discloses a method for finding network boundary roaming by deeply digging a call ticket. A neighbor city base station subdistrict which joins in a boundary roaming preferential charge range is chosen in a border region; a local mobile user in a signal intersection coverage of the neighbor city base station is determined; when a boundary roaming charge base station subdistrict in relation to the user appears near the base station subdistrict of the neighbor city, a boundary roaming charge suspicious boundary subdistrict appearing near the base station of the neighbor city can be located by extracting a roaming call list of the defined local mobile user to carry out active real-time screening and examining; the system easily realizes initiative discovery and real-time early warning on the suspicious boundary subdistrict, generates revolutionary innovation on discovery and treatment system of boundary roaming complaint, brings new breakthrough on timeliness and accuracy of boundary roaming discovery and treatment.

Description

technical field [0001] The invention relates to the field of communication network operation and maintenance management, in particular to an effective method suitable for communication operators to strengthen edge roaming management, effectively reduce edge roaming complaints, and improve customer satisfaction. Background technique [0002] "Boundary roaming" refers to the phenomenon that the base station signals cross coverage in the border areas between different cities, and users occupy the base station signals of other cities when using their mobile phones without going out of the city borders, and generate roaming charges. This phenomenon is not a special case of a certain city or province, it generally exists at the junction of administrative divisions across the country; as the wireless environment changes due to network cutover adjustments and network element changes, the corresponding preferential billing does not take effect in time, etc. Coupled with factors such ...

Problems solved by technology

[0005] In order to solve the shortcomings of the existing edge roaming problem, the present invention mainly utilizes the method of actively discovering the edge roaming problem through deep mining of the user’s roaming bill, especially according to the fact that roaming occurred in a neighboring city cell occupied last month but no roaming fee is charged. Single record to find out the border target users, combined with these target users occupying adjacent cities and towns every day to collect roaming charges, and locate the border problems of each city as a suspicious border cell, and supplemented by the number of occupations and occupation ratios of suspicious border cells As well as GIS maps, confirm the missing border cells, and then submit preferential billing in time
