METHOD AND NETWORK DEVICE FOR IDENTIFYING A USER BEHAVIOUR PATTERN IN A CELLULAR SYSTEM

摘要

It is presented a method for identifying a user behaviour pattern in a cellular system (4). The method is performed by a network device (20) of the cellular system and comprises the step of collecting (40) data of services a user of the cellular system has used and at what time. The method further comprises the steps of dividing (42) the collected data of services into time intervals; defining (42) at least one value vector for each time interval of the time intervals, by association rule mining the collected data of services;and comparing (43) the value vector of each of the time intervals with the value vectors of an adjacent time interval and grouping adjacent time intervals having a minimum distance between value vectors thereof. The method also comprises the steps of: combining (44) the value vectors of each time interval of grouped adjacent time intervals, thereby defining a value vector for each time interval of a reduced number of time intervals;comparing (45) the value vector of each time interval of the reduced number of time intervals with the value vectors of an adjacent time interval and grouping adjacent time intervals having a minimum distance between value vectors thereof; and repeating (46) the steps of combining and comparing the value vector of each time interval of the reduced time intervals, until a value vector is combined into a single time interval. A corresponding network device, computer program and computer program product are also presented.
