Abstract: Method for estimating the number of people present within a given geographical area, with at least a portion of the people being equipped with cellular terminals that communicate according to at least two predefined communication standards. The method includes the steps of: (a) using a traffic analysis on the one or more networks present in the predefined area, carried out using at least one traffic analyzer located in the area and with a range chosen according to the area to be covered, detecting, for each of the standards, at least one indicator that represents the activity of a terminal on the network(s) and operating according to at least the same standard, (b) deducing the indicators thus detected, counting the number of cellular terminals present in the area, (c) estimating the number of people present in the area, using at least one law of correlation between the number of cellular terminals thus counted and the corresponding number of people present in the area.

Abstract: A system and method for strong authentication achieved in a single round trip is disclosed, which reduces the amount of time needed for a mobile node to be authenticated by the network. In an embodiment of the present invention, the, authentication time is approximately three times faster than for 3GPP.

Abstract: A system and method for fast GPRS for IPv6 may improve data transfer efficiency in mobile networks, for example, in networks that relay on the GPRS infrastructure as defined and standardized in the European Telecommunications Standards Institute (ETSI), and on mobile IPv6 as standardized in the IETF. Mobile IPv6 techniques may be applied in the context of GPRS to transform mobility management into a routing problem, for example, by translating the routing area identifier into a part of the routing prefix in IPv6. Similar mobile IPv6 techniques also may provide an evolution path toward internetworking using native mobile IPv6.
