A method performed by a user equipment, UE, (140-1) in a cloud computing system, the method comprising: performing a registration for each of a first cloud hub and a second cloud hub , wherein the first cloud hub and the second cloud hub are registered to a public personal cloud system ; selecting , based on a user input, a service scheme, the service scheme including a public access having access to the public personal cloud system and receiving service, and a local access having access to a currently accessible cloud hub and receiving service; if the service scheme corresponds to the local access, transmitting , to the currently accessible cloud hub , a first request message for the local access, the first request message including an identifier, ID, and a password, PWD; receiving , from the currently accessible cloud hub , a list of service or contents providable in the currently accessible cloud hub ; if the service scheme corresponds to the public access, transmitting , to the currently accessible cloud hub , a second request message for the public access, the second request message including an ID and a PWD; receiving from the currently accessible cloud hub , the list of service or contents providable in the currently accessible cloud hub , the other registered cloud hub and the public personal cloud system , wherein the public access provides a cloud service in which the UE (140-1) accesses the public personal cloud system through the currently accessed cloud hub . performing a registration for each of a first cloud hub and a second cloud hub , wherein the first cloud hub and the second cloud hub are registered to a public personal cloud system ; selecting , based on a user input, a service scheme, the service scheme including a public access having access to the public personal cloud system and receiving service, and a local access having access to a currently accessible cloud hub and receiving service; if the service scheme corresponds to the local access, transmitting , to the currently accessible cloud hub , a first request message for the local access, the first request message including an identifier, ID, and a password, PWD; receiving , from the currently accessible cloud hub , a list of service or contents providable in the currently accessible cloud hub ; transmitting , to the currently accessible cloud hub , a first request message for the local access, the first request message including an identifier, ID, and a password, PWD; receiving , from the currently accessible cloud hub , a list of service or contents providable in the currently accessible cloud hub ; if the service scheme corresponds to the public access, transmitting , to the currently accessible cloud hub , a second request message for the public access, the second request message including an ID and a PWD; receiving from the currently accessible cloud hub , the list of service or contents providable in the currently accessible cloud hub , the other registered cloud hub and the public personal cloud system , transmitting , to the currently accessible cloud hub , a second request message for the public access, the second request message including an ID and a PWD; receiving from the currently accessible cloud hub , the list of service or contents providable in the currently accessible cloud hub , the other registered cloud hub and the public personal cloud system , wherein the public access provides a cloud service in which the UE (140-1) accesses the public personal cloud system through the currently accessed cloud hub . <EOS>
