It is required to compare the information between the newly-built stations and the already operating base
stations and draw conclusions on the effect of newly-built base stations according to reasonable models or
algorithms.
It is required to support summaries of the effects of newly-built base stations in a certain area or construction
period.

9 Framework of big-data-driven networking – mobile network traffic management and
planning
[ITU-T Y.3650] describes the general framework of bDDN. As is shown in [ITU-T Y.3650], the bDDN framework
is made up of three planes, the big data plane, the management plane and the network plane. The framework
described in this Recommendation is based on the general framework presented in [ITU-T Y.3650]. The
framework described in this Recommendation focuses on the big data plane.

The framework of big-data-driven networking – mobile network traffic management and planning is shown
in Figure 9-1.

Layer I – Data colleting
The data collecting layer collects the signal data both in RAN and CN, the users' behaviour data and the
common parameter data.
Layer II – Data pre-processing

The data pre-processing layer extracts, transforms and then loads the data to data warehouses for storage.
Layer III – Data analysis

The data analysis layer has two main tasks, the real-time task and the off-line task. The real-time task
computes data items for multiple dimensions as long as the data from the mobile network is collected. The
off-line task computes data items for multiple dimensions at regular intervals. Besides the real-time and the
off-line task, the QoS sensing task senses the experience of mobile network users based on the result data of
the real-time and off-line task.

Layer IV – Application
Many applications can be generated based on the result data of the data analysis layer. The big-data-driven
networking - mobile network planning is one of these applications.
