A method distributes cell-level aggregated data available from a mobile communication network and aggregated at the level of single network cells. The method subdivides a geographic area in geographic area portions, and causes mobile terminals situated in the geographic area to calculate and provide respective geographic position estimates to a data processing system. An overall number of geographic position estimates are distributed by assigning to each geographic area portion a respective number of geographic position estimates. Cell-level aggregated data relating to a network cell is received, and for each network cell, covered geographic area portions are determined. The cell-level aggregated data of the network cell is distributed according to a respective distribution factor. A distribution map of the cell-level aggregated data is generated in which to each of the geographic area portions of the geographic area of interest a respective quota of the cell-level aggregated data is assigned.

Matrices of movement in a geographic area are computed. The method subdivides the geographic area into geographic zones. Each entry of a matrix includes an indication of movements from one geographic zone to another in the respective time slot. The geographic area of interest is subdivided into geographic area portions, and mobile communication terminals in the geographic area calculate and provide respective geographic position estimates to a data processing system. An overall number of geographic position estimates are distributed by assigning to each geographic area portion a respective number of geographic position estimates. Covered geographic portions are determined among said plurality of geographic area portions, and each one of the determined covered geographic area portions is assigned a respective weight. A correspondence map establishing a correspondence between the network cells and the geographic zones is generated, and the weights are used in computing the matrices.

A method of counting individuals reaching or leaving a transport hub includes defining at least two categories of individuals, each corresponding to a respective purpose to reach or leave the transport hub, and for each category, defining at least one respective category pattern associated with the category. Each category pattern is a sequence of events of interaction between a User Equipment and a communication station. The method also includes acquiring event records associated with User Equipment from the mobile telecommunication network, searching the event records associated with each User Equipment to identify sequences of events of interaction matching a category pattern, and upon finding a match, increasing a number of individuals belonging to the category associated with the category pattern.

Method and system for identifying significant locations through data obtainable from a telecommunication network

A terminal is authenticated in view of inclusion in a communication network by an authentication process conditioned upon location information transmitted from the terminal to at least one server in the network. At least one access point for the terminal to the network is configured for allowing a non-authenticated terminal to transmit to an authentication server in the network authentication messages based on a given authentication protocol, such as, e.g., EAP. The terminal is configured for transmitting the location information to the authentication server by conveying it over the authentication protocol. A location system can be integrated in the terminal to generate location information identifying the location of the terminal, and in that case the terminal is configured for transmitting the location information identifying the location of the terminal to authentication server. As an alternative, a location server is associated with the network and the location information is transmitted from the terminal to the location server. On the basis of the location information transmitted from the terminal, the location server generates location information identifying the location of the terminal and sends the information to the authentication server.
