Abstract: A communication method of a first device over a first radio communication link of a first communication network and a second device over a second radio communication link of a second communication network, includes a step of suspending, during a suspension time interval, transmission of a first signal by the first device over the first radio communication link; and a step of receiving, with the second device, a second signal over the second radio communication link during the suspension time interval.

Abstract: For supervising the security of a computer system (SY) comprising several elementary computer items (BI), such as machines and applications, and several gathering items (BIg), such as networks, services or sites, gathering elementary items, a supervision device (DS) collects base measurements (MB) representative of states of the elementary items. A unit (UDI) determines several security indicators (I) of different types for each elementary item according to respective functions of the base measurements and several security indicators of different types for each gathering item. Each security indicator of a given type of a gathering item is determined according to a respective function of the security indicators of the given type of the elementary items gathered in the gathering item. The indicators of one item relate to the availability, the intrusion, the vulnerability and the compliance to a security policy.

Abstract: In order for professional mobile terminals for a critical mission of public security to make use of the radio infrastructure of a broadband network, for instance of the LTE type, the downward and upward frames are configured in a base station each in a first area dedicated to mobile terminals of lower priority and a second area dedicated to mobile terminals of critical mission of high priority. In the second area, sub-channels dedicated to a group of terminals of critical mission are allotted by order of priority to this group, to another group of mobile terminals of critical mission and to mobile terminals of lower priority.
