Abstract: The invention relates to a method for authenticating to a mobile network. According to the invention, the method comprises the following steps. A device activates only a first temporary subscription identifier. The device sends to a first server the first temporary subscription identifier and first data. The first server sends to the device a first result message including an authentication failure based upon the first data. The device activates only a second temporary subscription identifier. The device sends to the first server the second temporary subscription identifier and second data. And the first server sends to the device a second result message including an authentication success based upon the associated first and second temporary subscription identifiers and the second data. The invention also relates to corresponding device and system and a server for authenticating devices to a mobile network.

Abstract: A roaming device sends, through a visited network and a proxy network, to a home network, an identifier for a first subscription. The home network sends, through the proxy network, to the visited network, data relating to the first subscription. The proxy network sends to the home network a first temporary address. The visited network sends to the proxy network a second temporary address. The device activates a second subscription. The device sends, through the visited network and the proxy network, to the roaming provider network, an identifier for the second subscription. The roaming provider network sends, through the proxy network, to the visited network, data relating to the second subscription. The proxy network registers the first subscription identifier, the second subscription identifier, the first temporary address and the second temporary address. The proxy network sends to the roaming provider network the first temporary address.

Abstract: The invention is a method for authorizing a device to establish a communication session with an access point of a WLAN. A secure token comprises a data related to a telecom network subscription and is connected to the device. The device comprises credentials required for establishing the communication session with the access point. The method comprises the following steps: asking the secure token to initiate an authentication by using the data, running an authentication process initiated by the secure token by using the data and a communication channel provided by the telecom network, in case of successful authentication, sending an authentication pattern from the secure token to the device, authorizing use of the credentials thanks to the authentication pattern in the device and establishing the communication session between the device and the access point by using said credentials.

Abstract: The invention concerns a method for attaching a roaming telecommunication terminal to a visited network, the terminal having a security element. The method includes transmitting from the home network to the terminal a rejection message that is function of the features of the terminal and the security element.

Abstract: A method for managing a subscriber device includes a first detection step in which a first device detects a first status relating to a presence of a subscriber device under a radio coverage of a home mobile network. In the first detection step, the first device intercepts a message for requesting whether the subscriber device has or has not been stolen, as request message, the request message originating from a Mobile Switching Center relating to the home mobile network and being addressed to an Equipment Identity Register relating to the home mobile network. A corresponding first device is also disclosed.

Abstract: The invention relates to a method for loading a list of preferred networks into a secure element contained in a mobile terminal. The loading is accomplished when the secure element detects that it is in a roaming condition within a telecommunication network. The method consists of: i) asking (12) for an IP channel to be opened between the telecommunication network and the secure element, the request for opening originating with the secure element; ii) requesting (13) the loading of the list of preferred networks; iii) uploading (14) via the IP channel the list of preferred networks into the secure element; and iv) transmitting (16) a request by the secure element to the mobile terminal to use one of said preferred networks in said list.

Abstract: The invention relates to a method for selecting a mobile telephony operator so as to allow a subscriber, having a main subscription, to enter into a roaming situation, wherein said subscriber is using a mobile terminal. According to the invention, the method involves: i) suggesting the name of at least one alternative operator network, capable of providing roaming service, to the subscriber having a main subscription, said suggestion being accompanied by an indication of the roaming rate charged by said alternative operator network; and ii) after the user selects an alternative operator network, sending an IMSI to the mobile terminal, which enables said user to be connected to the alternative operator network so as to benefit from the roaming rate thereof.

Abstract: The present invention provides a method for steering a handset's user on preferred networks while roaming, said user being able to move from a home network to a visited network characterised in that on detecting a roaming event, the handset automatically switches from 2G/3G visited networks to Wi-Fi preferred networks when available.
