existing mobile network planning methods are unable to ensure the veracity and validity required for mobile
network construction.

In the mobile network, a great deal of traffic data both in the user and in the signal plane is generated all the
time, which reflects the real status of mobile network itself and customers' actual experience when they are
using services. Based on this information, more efficient management and reasonable planning of mobile
networks could be achieved.

Therefore, the question of how to drive mobile network traffic management and planning using big data
related technologies should be considered.

7 Requirements of big-data-driven networking - mobile network traffic management
In a mobile network, a great deal of traffic data is generated all the time. This data includes information
related to users' behaviours, network control processes and the status of the network. By collecting and
analysing big data, information the running status and real utilization of the mobile network itself and even
users' real service experiences can be obtained. In addition, driven by this information mining from big data,
comprehensive and efficient traffic management for the mobile network can be achieved. This clause
specifies the requirements of big-data-driven networking – mobile network traffic management.

7.1 Data categories
There are three categories for the data needed to be collected from the mobile network:

– Signal data
– Users' behaviour data
– Common parameter data
7.1.1 Signal data

The signal data transfers over the mobile network, records the control processes and reflects the running
status of the mobile network.
Signal data comprises two aspects; signal data in the radio access network (RAN) and signal data in the control
plane of the core network (CN).
7.1.2 Users' behaviour data

The users' behaviour data reveals the users' actual behaviour in the mobile network. This data provides
insight into the true experience when users enjoy a service in the mobile network. The users' behaviour data
is collected from the user plane of the CN.

7.1.3 Common parameter data
The common parameter data is the data representing the information of base stations and cells in the mobile
network, describing the application information and the users' information. It can be correlated with the
users' behaviour data and the signal data.

7.2 Requirements related to data categories
The scopes and sources for different categories of data are required as follows:

7.2.1 Signal data

7.2.1.1 Signal data in the RAN
There are three types of signal data in the RAN. They can be collected from network management and control
elements.
1) Performance Measurement (PM) data

PM data records performance information of a mobile network.
