The present invention relates to a system for determining which subscriber class the said subscribers belong to by using the data about mobile network, fixed network and value-added services usages of mobile network operator subscribers.

Background of the Invention

Today, mobile network operators can evaluate their subscribers under various classifications in order to provide customized services to the said subscribers and make offers suited for subscriber characteristics. Information such as age, income group, profession, place of residence, gender should be known so that a subscriber can be included into a correct subscriber class. Although mobile network operators can sometimes access subscribers in order to obtain these information, it is not always possible to obtain these information completely and correctly.

In addition, preventing realization of subscriber classification in a correct way is another case that is common among mobile network operator subscribers. This case is such that a subscriber does not always use a line that is registered to his/her name. Some subscribers are only the user of the lines being used at that moment and real line holders are completely different persons (for example, another family member). Because subscribers using the lines that are registered to another person's name cause acquisition of particularly subscriber information in a wrong way, it is not always possible to include these subscribers into a correct subscriber class. Including mobile network operator subscribers into a correct subscriber class is a determination of vital importance in terms of mobile network operators in order to know the subscriber better, adjust services to be provided and recommended to the subscriber accordingly. When laborious and inadequate methods for determining the information to make this classification is taken into account in the state of the art, together with importance and criticality of this determination, it is understood that a more effective solution wherein classification of a mobile subscriber is made by taking usage data into consideration is necessary in the state of the art.

The Chinese patent document no. CN103428370, an application in the state of the art, discloses a method for determining whether a mobile phone has multiple users or not. In the method, it is enabled to detect whether the user is line holder or not by comparing the user information wherein the mobile device is registered with the SIM card information being used in the mobile device.

The United States patent document no. US2010293165, another application in the state of the art, discloses a subscriber identification system. In the said system, it is enabled to detect and identify a certain subscriber within a group of subscribers by examining subscriber usage data.

Summary of the Invention

An objective of the present invention is to realize a system for determining which subscriber class the said subscribers belong to by using the data about mobile network, fixed network and value-added services usages of mobile network operator subscribers.

at least one data collection unit (2) which collects data about subscribers' usages of mobile network, fixed network and value-added services from different data sources (V);

at least one data interpretation unit (3) whereto the data collected by the data collection unit (2) are transferred and which enriches the data by carrying out summarization and interpretation transactions on these data and generates meaningful variables for each subscriber; at least one data learning unit (4) which carries out learning transaction by means of machine learning methods on the data of the type determined by the data interpretation unit (3) and generates an estimation method; at least one estimation unit (5) which realizes an estimation about in which subscriber class each subscriber should take part by running the model generated by the data learning unit (4) for the subscribers and can transfer the estimation results to various terminal systems (U); - at least one database (51) which keeps the data about the estimations managed by the estimation unit (5) and realized by the estimation unit (5). (Figure 1)

The data collection unit (2) is a unit which collects data about subscribers' usages of mobile network, fixed network and value-added services from different data sources (V) and carries out summarization and interpretation transactions on these data.

In preferred embodiment of the invention, the data collected by the data collection unit (2) from data sources (V) are history of network performance indicators; location history of subscribers that emerge with their signalling and call detail information occurring by their mobile network usages; data about their mobile data usages; data of TV and entertainment usage and purchase that is received from fixed and mobile network system; history of music usage; data about data usages performed over fixed networks; information of the mobile device that is used by the subscriber; data about club, line ownership or usership, membership information of the subscribers on the mobile network operator.

The data interpretation unit (3) is a unit whereto the data collected by the data collection unit (2) are transferred and which enriches the data by carrying out summarization and interpretation transactions on these data and generates meaningful variables for each subscriber.

In one embodiment of the invention, the data interpretation unit (3) determines POI (Point-of-Interest) information (such as university, ^' hospital, plaza, AVM, concert, stadium) over the location history collected by the data collection unit (2) and enriches these location information. Similarly, the data interpretation unit (3) analyses the data about the mobile data usage collected by the data collection unit (2) and the data about the data usages realized over the fixed networks and determines over which applications or sites these data usages are realized by exhibiting fields of these applications and sites (such as game, social media, health, music). Thus, the said data usage data are enriched.

The data learning unit (4) is a unit which carries out learning transaction by means of machine learning methods on the data whereon the data interpretation unit (3) carries out summarization and interpretation transactions and the variables generated by it and creates an estimation model.

In preferred embodiment of the invention, the data learning unit (4) carries out learning transaction by means of regression method which is one of machine learning methods.

The data learning unit (4) is a unit which periodically realizes learning and model development applications in preferred embodiment of the invention. Thus, it is ensured that the estimation model is updated together with new data occurred in time and new variables generated.

The estimation unit (5) is a unit which realizes an estimation about in which subscriber class each subscriber should take part by running the model generated by the data learning unit (4) for the subscribers and can transfer the estimation results to various terminal systems (U) such as marketing, planning systems.

The estimation unit (5) can runs the said model for all subscribers in one embodiment of the invention whereas it can run the model for a certain group of subscribers as well. The said subscriber groups, in different embodiments of the invention, can be subscriber groups such as subscribers changing tariff/bill, new subscribers, subscribers realizing new service purchase, subscribers experiencing/realizing change of classification/club/membership, subscribers changing device, subscribers whose data on the HLR (Home Location Register) changes. The estimation unit (5) is also a unit which has the quality to realize the estimation transaction again for all subscribers or one or several subscriber group in the event that the estimation model changes/is updated as a result of the transactions realized by the data learning unit (4). In one embodiment of the invention, the estimation unit (5) is a unit which has the quality to test the model created by the data learning unit (4) by using a control data and to determine whether the model has exceeded the correct estimation threshold value or not. As can be understood by a skilled person in the art, classes that can be determined for subscribers as a result of estimation realized by the estimation unit (5) can consists of various subscriber classes such as "High Income Group Subscribers", "White Collar Employee", "University Student", "The Youth Under the Age of 26" in different embodiments of the invention.

The database (51) is a unit which keeps the data about the estimations managed by the estimation unit (5) and realized by the estimation unit (5).

With the inventive system (1), transaction of determining which subscriber class the said subscribers belong to by using the data about mobile network, fixed network and value-added services usages of mobile network operator subscribers is carried out. When the said transaction is carried out, firstly the data collection unit (2) collects data about subscribers' usages of mobile network, fixed network and value-added services from various data sources (V). Then, the data interpretation unit (3) enriches suitable data by carrying out summarization, interpretation transactions on these data received by the data collection unit (2). Thus, a large number of variables whereon analysis can be made are created specific to each subscriber. The data learning unit (4) carries out learning transaction by means of machine learning methods and it creates an estimation model for determining into which subscriber class a subscriber should be included, on the data wherein the data interpretation unit (3) carries out summarization and interpretation transaction and the variables generated by it, based on the information about which subscriber class does the subscriber belong to for the cases in these said data. In one embodiment of the invention, this model is a model wherein environmental factors are also taken into account together with information of calling/being called and information of social network analysis. This model is tested by the estimation unit (5) at first and if it is detected to have exceeded a certain estimation threshold value, it is started to be used for all subscribers or a selected subscriber group by the estimation unit (5) for the purpose of determining into which subscriber class subscribers should be included according to the usage data and thus it is ensured that subscribers are placed into a subscriber class suitable for their usage data. The estimation unit (5) is a unit which has the quality to transfer estimation results to different terminal systems (U) and also to write them to a database (51). Within these basic concepts; it is possible to develop various embodiments of the inventive system (1), the invention cannot be limited to examples disclosed herein and it is essentially according to claims.
