Embodiment Construction

[0039] The invention relates to a secure method for copying at least part of information (104) from a SIM card (10) to at least one communication object (2). The invention also relates to a system applying the method. The system according to the invention comprises a mobile device (1), such as a mobile phone, at least one communication partner (2), such as one or more mobile phones or other one or more PDAs (Personal Digital Assistants) and at least one operator device (3). In terms of operator equipment (3), the entire equipment of a given operator will be considered (authentication center, nominal location register, etc.), allowing the identification and connection of mobile phones within their area of ​​influence. For reasons of simplicity, this will be considered a single terminal, although it is clear that it is actually a network comprising several devices communicating with each other. The operator's network is organized in the form of trunks, with a central terminal ...

Abstract

The process involves sending a request to clone an international mobile subscriber identity (IMSI) related to a subscriber identity module (SIM) card, by a mobile equipment e.g. mobile telephone, to an operator equipment. The IMSI and an international mobile equipment identity (IMEI) of a communicating object are authenticated by the latter equipment, and an IMSI clone is created. The card data is stored in the object`s storing units. An independent claim is also included for a system for duplication of information of a SIM card.

Description

technical field [0001] The present invention relates to the field of communication, in particular to mobile phones. More specifically, the present invention relates to a method and a system applying the method, allowing subscription subscribers to use different communication objects while physically only having one SIM (Subscriber Identity Module) card. Background technique [0002] Mobile telephone networks are operated by operators who provide telephone access to their subscribers, whose identifiers (IMSI, International Mobile Subscriber Identity), directory numbers and profiles are recorded on the operator's logo Called location register (localization register) (HLR, home location register) and verification center. The user has a mobile device identified by a serial number (IMEI, International Mobile Equipment Identifier) ​​and contains a SIM card in which the subscriber's IMSI is further stored. When the subscribed user uses the operator's network, he / she sends the IMS...
