A mobile device and a communication method that enable to collect location information without imposing a load on the mobile device and the network. In the mobile device, a communication module receives a notification signal including a cell ID from a base station and a determining module determines whether the cell ID included in the notification signal corresponds to a cell ID stored in a storage module. A positioning module performs measurements of the location and the communication module notifies the location information thus measured. Thereby, a management center is capable of collecting the location information of the mobile device located in a given area and it is possible to realize processing to efficiently collect the location information by reducing a load on the mobile device and the network.

Provided is a mesh data creation method allowing appropriate expression of population densities while making a balance between accuracy and granularity. In the mesh data creation method, when the number of samples in a region of reference mesh data with a predetermined size is not less than a threshold, divided mesh data is created by dividing the region of the reference mesh data. Namely, each portion with a high population density can be expressed by a fine region of mesh data and each portion with a low population density by a coarse region of mesh data. The above makes it feasible to prevent meshes from becoming too fine to ensure accuracy or, conversely, from becoming too coarse to maintain granularity, thereby resulting in failing to achieve a detailed grasp of population densities, and thus to achieve appropriate expression of population densities while making a balance between accuracy and granularity.

A mobile station, a communication system, and a communication method that are capable of efficiently collecting location information of any user. A communicating module receives a positioning request including attribute specifying information from a management center, a determining module determines whether measurements of the location are necessary or not based on the attribute specifying information in the received positioning request and the attribute information stored in advance. Then, when the determining module determines that measurements of the location are necessary, a positioning module performs measurements of the location and sends location information thus measured to the management center. Accordingly, it is possible to collect the location information of the mobile station that agrees with an attribute that the management center desires and therefore, it is possible to provide an attentive service and the like based on the location information.

An information processing device and a method for estimating a number of terminals, which can accurately count a number of mobile terminals in an analysis target region of which address attribute is an adjacent region, taking the intake phenomenon into account. A terminal counting portion counts numbers of first and second position information pieces. An intake coefficient calculation portion calculates an intake coefficient based on the numbers of position information pieces. An intaked terminal calculation portion calculates a number of intaked terminals based on the counted number of position information pieces at an analysis target time and the calculated intake coefficient, subtracts the number of intaked terminals from the number of position information pieces, and calculates an estimated number of mobile terminals.
