Abstract
The procedure for transmitting SMS messages with protected identity prevents the recipient of an SMS message from seeing the caller's telephone number, and therefore the corresponding personal data, but allows him to contact the caller by sending an SMS message. During the procedure, the service manager ciphers the user's telephone number, contained in the message header, and then subsequently deciphers it to restore the original telephone number.
Claims5
Process for the transmission of SMS messages with protected identity, in which the callers telephone number is contained in the header field (OADC) of the SMS messages sent, the SMS message sent by the user with his telephone number visible being received and processed by a SMS message service centre (SMSC), characterised by the fact that the SMS message is then forwarded to transit equipment (GW) where it is ciphered with an application based on a suitable algorithm, and then transmitted to its destination, which can not trace the identity of the user from the ciphered telephone number, but which can reply by using the ciphered number, due to the fact that the transit equipment (GW) is enabled to decipher the number and restore it to its original form, and then forward the call correctly.
