Method for dynamically configuring entities of a communications network for routing data from a visitor terminal

A configuration device implemented in a control entity of a second network and comprising:

• a processor;
• and
• a non-transitory computer-readable medium comprising instructions stored thereon, which when executed by the processor configure the configuration device to configure at least one terminal of a client user of an operator managing a first communications network, prior to attachment of the at least one terminal to the second communications network whose transmission resources are temporarily used to route data from the at least one terminal to a remote server, the configuring comprising:
• receiving, from a control entity of the first network, a management instruction relating to the attachment of the at least one terminal to the second network for a geographical area,
• configuring an item of data relating to controlling the attachment of the at least one terminal on the basis of the received management instruction, and
• sending, to the at least one terminal, at least one configuration parameter for the attachment of the at least one terminal to the second network.

A terminal of a client user of an operator managing a first communications network, able to attach to a second communications network whose transmission resources are temporarily used to route data from the terminal to a remote server, the terminal comprising:

• a receiver configured to receive,
• from a control entity of the second network, at least one configuration parameter for attaching the at least one terminal to the second network,
• an attachment control message comprising conditions of attachment to the second network,
• a processor;
• and
• a non-transitory computer-readable medium comprising instructions stored thereon, which when executed by the processor configure the terminal to update a list of networks that the terminal is able to access and a geographical area associated with the networks.
