Method for transmitting data and related service data

摘要

A method of transmitting data and service information associated with said data, including an addressing step during which a set of service information D(Si) that is intended to be stored is referenced by means of an address AD. The address AD includes a session identifier Si, a session being defined as a string of successive activations of different communications means. Service information D(Si) is marked unequivocally by means of an identifier Si that is invariant throughout the session concerned. Thus no element external to that session can reach or degrade the service information, and its permanence is guaranteed until the end of the session.

1. A method of transmitting data and service information associated with the data, the method comprising:
establishing an address for storing and referencing by means of the address a set of service information received from a user terminal, wherein the address comprises a session identifier for a session initiated by the user terminal; generating a call identifier which is used to form part of the address assigned to the set of service information and which is linked temporarily to the session identifier; transmitting the call identifier via a signaling link set up between two communications devices; and generating first and second branch identifiers each linked to the session identifier, the generating being done at the time of establishing first and second links both involving a same source communications device, any call identifier which is transmitted by the source communications device via one of the first and second links being then linked both to the session identifier and to one of the first and second branch identifiers, respectively.
