            Evaluating closeness (both geographic and social) among users in the same base station requires collection
            of the following:
            1)      geographic data: the location and mobility pattern of users;
            2)      social data: the social characters of users, including contact information and device information;

            3)      network data: wireless channel states, including channel fading and interference.
            6.8.2   Big-data-driven resource allocation based on mobile user moving behaviour

            According  to  mobile  user  moving  behaviour,  resources  are  allocated  to  each  base  station  with  a  fixed
            configuration, resource utilization must be underestimated. On one hand, it is difficult for users in a hotspot
            to obtain good QoE during peak hours. On the other, resources may be greatly wasted in idle times at low
            traffic locations.
            Current and historical data can be utilized by data analytics to predict traffic for high-density areas in the
            networks. Using the respiratory effect of the base station may help to accurately serve the right place at the
            right time, promoting recourse utilization.
            To adjust the recourse utilization of the base station, it is necessary to collect the following:
            1)      network data: the wireless channel states, including channel fading and interference;
            2)      user data: the location and access pattern of users that can be collected from the interface between
                    service general packet radio service (GPRS) support node (SGSN) and gateway GPRS support node
                    (GGSN).

            6.9     Big-data-driven network planning and design
            In most traditional deployment cases, the sites of cells in mobile network are not optimized due to insufficient
            statistical data. By tracking mobile devices, their detailed activities can be recorded to provide real-time
            where, when and what information about mobile users in the network. A feasible solution is to make use of
            both network and anonymous user data including dynamic position information, and other various service
            features. Consequently, massive volume, velocity and variety of data need to be processed by advanced
            analytics techniques, which can transform the data into actionable knowledge. In order to understand traffic
            trends well, it is imperative to analyse the data in relation to corresponding content and events.
            Given the actionable knowledge inferred from big datasets, the MNOs can make wise decisions about where
            and how to deploy cells in the networks. This also allows them to predict traffic trends and prepare plans for
            future investment.

            Network design can be more efficient and reasonable with comprehensive data study of network status,
            external environment and various elementary issues.

            Analysing  customer  behaviour  in  their  use  of  network  services  is  crucial  to  understand  traffic.  Thus,
            concurrent weather and temperature data and social event information are taken into consideration to
            better understand traffic.

            6.9.1   Big-data-driven mobile network planning and construction based on customer experience
            When mobile customers use the services provided by MNOs, big data is generated both in the user plane and
            signal plane. By analysing them comprehensively, actual user experience in their use of services can be
            determined. According to the experience of users within the same base station, a judgement can be made
            about whether the base station is poor. A reasonable and intelligent plan to increase quantity or expand
            capacity of the base station can then be made to improve mobile network quality efficiently. Figure 6-8 shows
            the architecture of big-data-driven mobile network planning and construction.
