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.

Method and system for distributing, across a territory, data aggregated at a mobile communication network cell level

A method including subdividing a geographic area of interest in geographic zones; subdividing the geographic area of interest in geographic area portions; causing mobile communication terminals situated in the geographic area of interest to calculate respective geographic position estimates; distributing an overall number of geographic position estimates; receiving indications of events of interaction between the mobile communication terminals and network cells; identifying, for each one of the stored indications of events of interaction, the network cell in which the event of interaction occurred; building an array of presences in which each geographic zone has assigned thereto a respective indication of a respective number of events of interaction occurred in the identified network cells which have, in the geographic zone, a cell weight greater than a predetermined cell weight value, and providing the array of presences in output for estimating presence of individuals on a territory.

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 providing forecast of road transit times on roads of a monitored roads network, can include receiving a forecasted road transit time indication calculated by a road traffic monitoring system in respect of at least one road of the monitored roads network; and correcting the received forecasted road transit time indication based on information obtained from a cellular mobile communications network. The information includes information related to mobile terminals connected to the cellular mobile communications network and engaged in calls, and located in the neighborhood of the at least one road.

Method and system for forecasting travel times on roads

A method of estimating road traffic on a roads network, comprising: receiving information from at least one information source, wherein the information received from the at least one information source is one among a first information type and a second information type; defining at least two different information processing methods, each one associated with a respective one of said information type; selecting the information processing method based on the available information type and on predefined criteria; and processing with the selected information processing method the corresponding available information type; and providing an estimation of the road traffic based on the result of said processing.

The system allows determining whether at least one terminal belongs to a target space in a communications network in order to provide a set of services linked to the fact that the terminal belongs or does not belong to the above target space. The belonging is determined depending on at least one determination parameter. The services are associated with, preferably through a model, respective service specifications indicating the allowable error margin in determining whether the terminal belongs or does not belong to the target space. The determination parameters are changed depending on the above service specifications.

A road traffic monitoring system includes: a first input for receiving position estimations of mobile terminals; a second input for receiving input specifications chosen depending on the type of service for which such monitoring is performed; and an output for generating road traffic maps, each road traffic map being associated with a set of territory elements and including, for each one of the territory elements, at least one mobility index of mobile terminals travelling within such territory element. Preferably, input specifications are chosen among at least two of the following parameters, territory element, territory element observation time slot, and maximum allowable error on the estimation of at least one mobility index.

Triggers for the provision of location based services in a mobile communication network supporting a plurality of mobile terminals over a given territory, are generated by defining a set of target areas within the territory covered by the network, each target area being identified by respective geographic data, transforming the geographic data in a respective set of values of network related entities, the respective set of values being expected to be encountered by a mobile terminal when located in the corresponding target area, monitoring the values in the respective set as experienced by at least one monitored mobile terminal in the mobile communication network, checking whether the values as monitored match with the set of values are expected to be encountered, and when a match is found, which is indicative of the monitored mobile terminal being located in a given target area of the set, generating a trigger for prompting delivery of location based services related to the target area considered toward the monitored mobile terminal.

The invention relates to the decoding of charging data records (CDR) generated in a mobile telephone network. These records consist of files to be decoded that can be described on the basis of a formal description of the ASN.1 type. On the basis of: i) a description of the type of record to be decoded corresponding to at least a first type (GSM) and at least a second type (GPRS) of records to be decoded, and on the basis of ii) said formal description of the type ASN.1 of the records to be decoded, an interpreter of the ASN.1 type () self-generates an updated version of decoder () of at least a first and at least a second type according to the type of record to be decoded. The files to be decoded are sent to the decoder created in this way, so as to output the decoded CDR records in text format.
