5 Big data - Concept and application for telecommunications

8.1.3 Checking abnormal base stations

It is required to check the error conditions of base stations.
It is required to check base stations and cells which are in use or not. For those that are not in use, it is
required to compute lasting intervals and analyse whether they are abnormal or not.
It is required to check whether the traffic could belong to a base station or not. For traffic that could not
belong to a base station, it is required to check the base station information which occurred in users'
behaviour data.
It is required to manage abnormal base stations and correct their error conditions.
NOTE – The abnormal base station state mainly includes the cases of missing information, information that
changes dramatically, etc.

8.2 Requirement for the planning and construction of base station

In traditional mobile network planning, the base station is usually planned according to the customer
complaints and the drive test data. This data cannot reflect the customers' perception when they enjoy the
mobile network service.

The signal data and the users' behaviour data collected from the mobile network, the result data of the real-
time and off-line processing and the QoS sensing data reflect the status of the mobile network and the
customers' perception. By taking these data into account, mobile network operators are able to make better
decisions about where to construct base stations.

In addition, mobile network planning needs take the economic benefits into account. With limited resources,
base stations are built in areas where they can yield more benefit priority. This can be achieved by considering
user consumption information.

It is required to collect the users' personal data from a business support system (BSS), such as the users'
grade, the user pricing package, etc.

With the information of the base stations, it is required able to make models that can sense the users'
experience.

It is required for the models to sense the users under one base station, but it is also required to reflect the
whole mobile network base on the users' experience.
It is required for the models to correlate the users' experience and the performance of the mobile network
itself.
It is required for the models to take the users' grade into account.

It is recommended for the models to reflect the proportion of different types of data service.
When existing base stations cannot guarantee the demand of the users, it is required for the models to
indicate the sites where the mobile network is insufficient or badly adapted.
It is required for the models to be able to calculate where and how to construct a base station to satisfy the
demand of the users.
It is required for the models to be able to predict the trend of the traffic.

Based on the models that reflect the users' experience when they enjoy a mobile network service, a mobile
network similar to the users' actual demands can be constructed.

8.3 Evaluating the effect of newly-built base stations
It is required to evaluate the effects of newly-built base stations.
It is required to select already operating base stations with similar locations, network types and
configurations.
