Securing the Choice of the Network Visited During Roaming

A processing method of processing a request relating to a connection of a terminal beyond a range of the terminal's home network, to a network of a visited area covered by a plurality of networks, the method comprising the following acts performed by a mobility management entity of the visited network:

• receiving a request comprising an identifier relating to the visited area,
• obtaining, on the basis of the identifier, a list of at least one priority network of the plurality, to which the terminal must connect by priority, and
• sending a message of response to the request, comprising the list.

A device for connecting a terminal beyond a range of the terminal's home network, to a network of a visited area covered by a plurality of networks, the device comprising:

• a sender configured to send a request relating to the connection, comprising an identifier relating to the visited area,
• a receiver configured to receive a message of response to the request, comprising a list of at least one priority network of the plurality, to which the terminal must connect by priority, and
• a processor configured to disconnect the terminal and connect the terminal to a priority network of the list.

A non-transitory computer-readable medium comprising a computer program stored thereon, comprising instructions for implementing a method of connecting a terminal beyond a range of the terminal's home network, to a network of a visited area covered by a plurality of networks, when this program is executed by a processor of the terminal, wherein the instructions configure the terminal to perform acts comprising:

• sending a request relating to the connection, comprising an identifier relating to the visited area,
• receiving a message of response to the request, comprising a list of at least one priority network of the plurality, to which the terminal must connect by priority, and
• disconnecting the terminal and connecting the terminal to a priority network of the list.
