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.

A communication system aimed at easily and quickly collecting data regarding macroscopic population distribution, and easily and quickly obtaining survey results. An RNC of a communication system includes a signal-counting module that counts the number of signals indicating a quantity of signals transmitted and received between a mobile station and a BTS. An information analysis device includes a population distribution calculation module that calculates population distribution based on the number of the signals that the signal-counting module counts, and an output module that outputs the population distribution that the population distribution calculation module calculates.

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.

An object is to ensure reachability of data even with movement of a session between communication nodes. A home node HN-1 generates a home session address HSA-1 and establishes a session with communication correspondent. On the occasion of movement of the session, the home node HN-1 notifies a foreign node FN-1 that it desires to move the session to the foreign node FN-1. The foreign node FN-1 internally generates an IP address HSA-1, copies a state of the session in the home node HN-1, and thereafter notifies a communication mediator nodeof correspondence update information 'HSA-1&#x2192;HNA-2' in order to let the communication mediator nodepass data addressed to HSA-1 to a home node identification address HNA-2 by tunneling. The communication mediator nodepasses the data to HNA-2 by tunneling on the basis of the correspondence update information and another communication mediator nodeagain passes the data to a care-of address CoA-2 by tunneling.
