A method performed by a user equipment, UE, 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 (131, 132) and receiving service; if the service scheme corresponds to the local access, transmitting, to the currently accessible cloud hub (131, 132), 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 (131, 132), a list of service or contents providable in the currently accessible cloud hub (131, 132); if the service scheme corresponds to the public access, transmitting (207, 612, 622, 632), to the currently accessible cloud hub (131, 132), a second request message for the public access, the second request message including an ID and a PWD; receiving (616, 626, 636) from the currently accessible cloud hub (131, 132), the list of service or contents providable in the currently accessible cloud hub (131, 132), the other registered cloud hub (132, 131) and the public personal cloud system, wherein the public access provides a cloud service in which the UE accesses the public personal cloud system through the currently accessed cloud hub (131, 132). 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 (131, 132) and receiving service; if the service scheme corresponds to the local access, transmitting, to the currently accessible cloud hub (131, 132), 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 (131, 132), a list of service or contents providable in the currently accessible cloud hub (131, 132); transmitting, to the currently accessible cloud hub (131, 132), 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 (131, 132), a list of service or contents providable in the currently accessible cloud hub (131, 132); if the service scheme corresponds to the public access, transmitting (207, 612, 622, 632), to the currently accessible cloud hub (131, 132), a second request message for the public access, the second request message including an ID and a PWD; receiving (616, 626, 636) from the currently accessible cloud hub (131, 132), the list of service or contents providable in the currently accessible cloud hub (131, 132), the other registered cloud hub (132, 131) and the public personal cloud system, transmitting (207, 612, 622, 632), to the currently accessible cloud hub (131, 132), a second request message for the public access, the second request message including an ID and a PWD; receiving (616, 626, 636) from the currently accessible cloud hub (131, 132), the list of service or contents providable in the currently accessible cloud hub (131, 132), the other registered cloud hub (132, 131) and the public personal cloud system, wherein the public access provides a cloud service in which the UE accesses the public personal cloud system through the currently accessed cloud hub (131, 132).
