Definitions

• the present invention relates to the mobile communications field.
• Object of the present finding is to obviate the above disadvantage by providing mobile phone users with the possibility of storing their alphanumerical information, such as for example telephone numbers and associated names, at a special data storage centre connected to the network, and of retrieving said information, storing it to the phone memory and to the SIM card again every time the users wishes so, through the exchange of SMS messages with said storage centre.
• alphanumerical information such as for example telephone numbers and associated names
• Another object of the prevent invention is to provide a procedure for storing the phonebook of a mobile phone to a special storage centre in a confidential and safe manner, without any risk for the user data of being intercepted during transfer over the network or being read when stored to the data storage centre.
• Such new function of mobile phones therefore allows the users to create a strictly confidential copy of their phonebook, or of any information in general, storing it to a memory area external to the phone, so that even when the user is forced to replace his mobile phone or the relevant SIM card, he can retrieve his information and store it again to the new phone or SIM card.
• Such objects and resulting advantages are achieved by a procedure for storing alphanumerical information sent by a mobile phone to a storage centre connected to the network according to at least claim 3, reported hereinafter.
• FIG. 1 shows a flow chart relating to the data storage request by the user
• FIG. 2 shows a flow chart relating to the data storage operation by the storage centre
• FIG. 3 shows a flow chart relating to the data retrieval request by the user
• FIG. 4 shows a flow chart relating to the data transmission operation from the storage centre to the requesting user.
• the storage procedure under discussion uses the date computation and processing capabilities provided by mobile phones and requires a computer, provided with a wide memory area, performing the function of data storage centre.
• Such computer must be connected to the telephone network and can belong directly to the service provider, or to any board authorised
• any mobile phone supporting wireless connection to the storage centre can send properly encrypted SMS messages to the centre containing the information to be stored, such as for example names and relevant phone numbers.
• the storage centre computer is configured to recognise messages and store their contents to a memory area reserved to the calling subscriber.
• the computer memory can therefore be divided in as many memory benches as the number of users enabled to use the data storage service provided by the service provider.
• the user needs to retrieve stored data, he sends a data request message to the storage data.
• the computer recognises the message and the sender, and generates a reply containing the requested information in an encrypted form.
• the reply message reaches the user's mobile phone, it is decrypted and written to the phone memory or to the SIM card. It should be noted that the user may request to retrieve both a single information as well as all data previously stored with a single request.
• This second option is especially useful and convenient when the user has to replace his phone or SIM card, since he can quickly store his phonebook to the new mobile phone.
• the user associates the information to be stored, for example a telephone number and an alphanumericat information, if any, such as a name associated to the number, to a memory position of the mobile phone or of the SIM card. Such position will then be used to indicate the information to be retrieved to the storage centre. If the information to be stored is also stored to the phone, the relevant position may be preceded by letter T. In addition, if the memory position is already occupied by a previously stored information, the user is warned. It should be noted that the information to be stored may be directly typed by the user, or retrieved from the phonebook or from incoming calls. b) The user is required to select whether he wants to store the selected information.

• the storage centre reads the requested memory position from the SIM or from the telephone. In this latter case the memory position may be preceded by a T. If a jolly character ("*") is read in place of the position number, the procedure generates a sequence of messages equal to the number of positions stored. On the other hand, if a single position is requested, a single message is
