Table I.6 – Big data based mobile network (3G/4G) billing detail query

Title Big data based mobile network (3G/4G) billing detail query
Description Telecom operators use big data application services to provide detailed billing information of
mobile network users. Telecom mobile network users use 3G/4G networks to access mobile
internet services using mobile devices such as mobile phones and tablet computers .The access
network devices, such as PDSN or combined GPRS service node (SGSN/CGSN) devices, record all
kinds of billing information of each of the mobile network users into a standardized format, such
as a charging detail record (CDR). A charging gateway function (CGF) modular collects different
charging records and forwards these charging records to the billing system. The billing system
keeps and processes all the CDRs from different CGFs and finally generates the charging bill for
each mobile user. Telecom operators set up big data infrastructure and store huge amounts of
user billing detail information.
Mobile network users could quickly query the detailed billing information based on the big data
infrastructure and big data applications. A mobile network user could get the statistics and
analytics information for instance in terms of time, type of website and applications accessed
through a 3G/4G mobile network for his/her internet access actions through 3G/4G mobile
networks..

Roles/sub-roles – CSN:DP
– CSP:BDAP
– CSP:BDIP
– CSC:BDSU
Figure

Pre-conditions – CSN:DP can provide CDR data of network users
Post-conditions – CSP:BDAP can have functionalities for providing analysis result of network users' CDR data to
the CSC:BDSU.
– CSC:BDSU could quickly query the detailed billing record for each internet access based on
the analysis result.
