A method for geolocating a terminal of a wireless communication system from measurements of a parameter representative of a radio signal exchanged between the terminal and base stations of the communication system. The method uses fixed base stations and a mobile base station which is displaced in a determined search area. During a predefined search period, the terminal emits several radio signals to the fixed base stations and the mobile base station. A precise geographical position can then be determined, on the one hand, from the measurements carried out during the search period for the different base stations, and on the other hand, from the geographical positions of the fixed base stations and from the geographical positions of the mobile base station at the different times of emission of the radio signals by the terminal.

Method and system for geolocating an object using a mobile base station

A terminal provided with an eUICC card having an incomplete provisioning profile. At least one missing datum essential to the establishment of a communication between the terminal and an access network of a first wireless communication system is not defined by default in the provisioning profile. In order to remotely configure the eUICC card, prior communication is established between the terminal and an access network of a second wireless communication system to transmit the missing data to complete the provisioning profile.

Method for assistance with the remote configuration of an eUICC card and system for implementing such a method

A method for transmitting, by a transmitter, a packet to a receiver of a communication system. The packet including data encrypted according to a symmetric key encryption protocol by determining the value of a generation information and determining an encryption key according to the value of the generation information. The data to be included in the encrypted packet to be transmitted is encrypted according to the encryption key. A truncated information is calculated based on the generation information. A verification code for the encrypted packet is calculated according to the encrypted data and the first portion of the generation information. The encrypted packet to be transmitted is formed according to the truncated information, the verification code and the encrypted data.
