Method for managing transport tunnels (bearers) of packet data services usable by a user in a LTE technology telecommunications network, wherein each data service is defined by set characteristics of quality of service having set values. The method defines aggregates of packet data services (500; 600), to which corresponding proprietary aggregated QCI identifiers are assigned, defined by aggregated characteristics of quality of service having corresponding aggregated values. Each aggregated value of a aggregated characteristic of quality of service is selected, among the values of the characteristics of quality of service of the data services to be aggregated, so as to ensure the use of the aggregated packet data services both when these packet data services are transmitted within the aggregate of packet data services (500; 600) and when these packet data services are transmitted individually within a corresponding transport tunnel having a corresponding QCI identifier of the standard type. The method further allows mapping between a proprietary aggregated QCI identifier or a non-aggregated standard QCI identifier to identify the quality of service QoS at the transport tunnel level and the corresponding IP-level service class, by assigning a numeral value (coloration) of DSCP in the corresponding field of the header of the IP packet. In addition, the method allows the definition and use of a parameter representative of the allocation priority level ARP associated to the aggregates of packet data services in order to manage at the best the network congestion conditions.

The present invention relates to a method for estimating the altitude of a target. Said method comprises: acquiring first quantities indicative of bistatic range measurements associated with a target and carried out on the basis of radio frequency signals received by a passive radar sensor and transmitted by at least three transmitters of opportunity, each of which transmits using a respective carrier frequency different from the carrier frequencies used by the other transmitters of opportunity; acquiring second quantities indicative of bistatic range rate measurements associated with the target and carried out on the basis of said radio frequency signals received by the passive radar sensor and transmitted by the at least three transmitters of opportunity; and estimating a two-dimensional kinematic state of the target on the basis of the first and the second quantities, said two- dimensional kinematic state comprising a two-dimensional position of the target defined by two coordinates expressed in a polar reference system in terms of range and azimuth, or in a corresponding Cartesian reference system, and a two- dimensional velocity of the target defined by two components expressed in the polar reference system in terms of range and azimuth, or in the corresponding Cartesian reference system. The method is characterized by further comprising estimating the altitude of the target and the elevation component of the velocity of the target on the basis of the two-dimensional kinematic state of the target and the first and the second quantities so as to minimize a functional related to at least the second quantities.

DYNAMIC RESOURCE ALLOCATION IN A MULTI-ROLE OR MULTI-FUNCTION SYSTEM
A multi-role or multi-function system (1) operable to perform a multi-role or a multi-function and configured to dynamically allocate requisite resources for performing antenna functions (EFMi) during a frame interval (tF) of the multi-role or the multi-function by: - determining whether the antenna functions (EFMi) are completely performable in the frame interval (tF), based on a time-sharing resource allocation procedure; and if not, allocating the requisite resources for performing the antenna functions (EFMi) during the frame interval (tF), based on a time-sharing resource allocation procedure and an antenna-sharing resource allocation procedure.

ANTI-PIRACY SYSTEM FOR THE MARITIME NAVIGATION IN CRITICAL AREAS, AND DEVICE FOR DATA EXTRACTION FROM ON BOARD SENSORS
The invention concerns a maritime anti-piracy system (100), for the recognition of suspect watercrafts (50) around one or more co-operating ships (30) to be protected, comprising: a shore-based control system (10, 20, 40), comprising: one or more centres (10), geographically distributed, comprising shore sensors (11, 12) for detecting watercrafts surveillance data; a central station (20) for collecting and elaborating watercrafts surveillance data; the shore-based control system (10, 20, 40) comprising a bi-directional communication network (40) between said one or more centres (10) and said central station (20), in such a way that the central station (20) be able to send commands to said shore-based sensors; a communication system between said one or more centres (10) and said one or more co-operating ships to be protected (30). The anti-piracy system being characterised in that it comprises: one or more devices (90), mounted on board of corresponding said one or more co-operating ships to be protected (30), for maritime surveillance data extraction from maritime surveillance sensors (12', 11'), which are mounted on board of corresponding said one or more co-operating ships to be protected (30) and are suitable to watch over the space around said one or more co-operating ships, said one or more devices (90) for data extraction being suitable to send said maritime surveillance data to at least one of said one or more centres (10) through said communication system; an identification and authentication system (13, 70) of said one or more co-operating ships to be protected (30), which functions through said communication system and is shared among said one or more centres (10) and each of said one or more co-operating ships to be protected (30), said central station (20) for collecting and elaborating data elaborating the data coming from said one or more centres (10), and therefore also from said one or more co-operating ships to be protected (30), and launching the relevant alarms in the case of recognition of suspected watercrafts (50). The invention further concerns a device for maritime surveillance data extraction from maritime surveillance sensors mounted on board.
