Technique for managing an activation state of a radio access module

A user device comprising:

• a module for radio access to a main network;
• an activated module for radio access to a secondary network, arranged for searching for a beacon signal of the secondary network if the module for radio access to the main network is deactivated, and for detecting a beacon signal of the secondary network broadcast by a transmitting device associated with an access point of the main network, said detecting indicating that said device is in a radio coverage zone of said access point and for receiving information broadcast on the beacon signal of the secondary network;
• and
• a control module, arranged for obtaining an identifier of the access point from said broadcast information, for activating the module for radio access to the main network on detection of a beacon signal and for initiating a connection to the main network by the intermediary of the access point identified by said identifier.

A system for access to a main network, comprising at least one access point of the main network, at least one transmitting device of the secondary network associated with said at least one access point and a user device comprising:

• a module for radio access to a main network;
• an activated module for radio access to a secondary network, arranged for searching for a beacon signal of the secondary network if the module for radio access to the main network is deactivated, and for detecting a beacon signal of the secondary network broadcast by a transmitting device associated with an access point of the main network, said detecting indicating that said device is in a radio coverage zone of said access point and for receiving information broadcast on the beacon signal of the secondary network;
• and
• a control module, arranged for obtaining an identifier of the access point from said broadcast information, for activating the module for radio access to the main network on detection of a beacon signal and for initiating a connection to the main network by the intermediary of the access point identified by said identifier.

A non-transitory recording medium readable by a user device on which a program for a user device is recorded, comprising program code instructions intended for controlling execution of steps of a management method, implemented by the device, for managing an activation state of a module for radio access to a main network of the user device, said device comprising moreover an activated module for radio access to a secondary network, when said program is executed by said device, the management method comprising:

• searching for a beacon signal of the secondary network if the module for radio access to the main network is deactivated;
• detection of a beacon signal of the secondary network broadcast by a transmitting device associated with an access point of the main network, said detection indicating that said device is in a radio coverage zone of said access point;
• receiving information broadcast on the beacon signal of the secondary network;
• obtaining an identifier of the access point from said broadcast information;
• after the detection, activation of the module for radio access to the main network;
• and,
• connection to the main network by the intermediary of the access point identified by said identifier.
