Abstract: The invention relates to a method to retrieve personal customer data of a customer for delivering online service to said customer, with the steps:—a service supplier (3) initiates the sending of a network identifier (51) of a mobile node (5), used to communicate with the online service supplier (3) and bound to the customer by a mobile network operator (7), to an application programming interface (API) platform (9) with a request to manage the customer data,—the API platform (9) identifies the mobile network operator (7) of the mobile node (5), and forwards the network identifier (51) and request to retrieve the customer data to said mobile network operator (7) of the mobile node (5),—the mobile network operator (7) uses the network identifier to identify the customer and sends the requested personal customer data contained in a data repository of the mobile network operator to the API platform (9),—the service supplier (3) retrieves the personal customer data at the API platform (9).

Abstract: The invention relates to a phase comparator making it possible to measure the phase displacement between several very high stability oscillators and having for this purpose a system of pairs of measuring cascades each being connected to an oscillator and supplying a first and a second signal. It also comprises a multiplexer, a counting circuit, a computer and a computer coupler making it possible to compare the first signals in pairs in order to obtain a measuring range in which is located the phase displacement between two given oscillators and making it possible to compare the two signals, in order to obtain the displacement measurements in said range.
