10 Reference points of big-data-driven networking – mobile network traffic management
and planning

Figure 10-1 – The main reference points of big-data-driven networking – mobile network traffic
management and planning

The main reference points of the big-data-driven networking – mobile network traffic management and
planning system are shown in Figure 10-1, the details about the reference points are presented as follows:
– Reference point C1: After been pre-processed, the collected data is sent to message queues to
compute a set of items for multiple dimensions in real time.
– Reference point C2: The pre-processed data is stored in a distributed file system for off-line
computing and further operations.
– Reference point C3: The pre-processed data stored in distributed file system is sent to an off-line
batch processing module to be analysed for multiple dimensions at regular intervals.
– Reference point C4: The result data of both the real-time task and the off-line task is sent to the
distributed file system for storage and further operations.

– Reference point C5: The interface between the stored traffic data and applications. One of the
applications, the base station management system, can detect and fulfil the loss of base station
information automatically via C5.

11 Performance considerations
It is required to consider performance in the stages of data collecting, data transmission, data pre-processing,
data storage and real-time data processing.

In the data collecting stage, there are some performance requirements:
– It is recommended to guarantee the completeness and accuracy rate in parsing the signal data and
the users' behaviour data.

– It is recommended to guarantee the filling rate parsed records of the signal data and the users'
behaviour data.
– It is recommended to guarantee the accuracy rate for users' service using information through
parsing the users' behaviour data.

In the data transmission stage, there are some performance requirements.
– It is recommended to reduce the losing rate of the signal data and the users' behaviour data which
is transferred from data collecting equipment to the centralized system.
