5 Big data - Concept and application for telecommunications

It is recommended to collect the PM data, such as call drop rate, handover success rate and so on.

Details about PM data can be found in [b-3GPP TS32.401].
2) Configuration management (CM) data
CM data records configuration information of a mobile network. It is helpful for providing overview
information on a mobile network.
It is recommended to collect CM data.

Details about CM data can be found in [b-3GPP TS32.106].
3) Measurement report (MR) data

MR data measures the intensity and quality of current serving or neighbouring cells, reported to the mobile
network by user equipment (UE).

It is required to collect MR data, including reference signal receiving power (RSRP) and reference signal
receiving quality (RSRQ) data.

Details about the MR data can be found in [b-3GPP TS25.111].
7.2.1.2 Signal data in the core network

The signal data in the core network is collected from the control plane and scatters into different interfaces
as shown in Figure 7-1.

Figure 7-1 – Interfaces between network elements in mobile network

– For second generation (2G) networks, it is required to collect signal data from interface A [b-3GPP
TS43.903] and from interface Gb [b-3GPP TS29.060].
– For third generation (3G) networks, it is required to collect signal data from interface Iu-CS [b-3GPP
TS25.410] and interface Iu-PS [b-3GPP TS25.410].

– For fourth generation (4G) networks, it is required to collect signal data from
interface S1-MME [b-3GPP TS36.413], interface S6a [b-3GPP TS29.272],
interface SGs [b-3GPP TS29.118] and interface S10 [b-3GPP TS29.274].

It is required that collected signal data in CN includes but is not limited to: who are the users, the network
type (2/3/4G), the location in the mobile network (which cell), the signalling procedure type, the start and
end time of the signalling procedure, the time delay of the signalling procedure, the result of the signalling
procedure (success or fail) and the reason why if the signalling procedure fails.
