4. Story for better understanding Hospital (a M2M service provider for mHealth) subscribes to the M2M subscription of the NO thus becoming a subscriber of the NO. Each M2M device of the hospital is authenticated by the NO and the hospital. There is secure communication between the (1) M2M device and the network, (2) network and hospital and (3) between the M2M device and the hospital. A company subscribes to mHealth service of the hospital for all its employees – thus the company is subscriber of the hospital and its employees are the users. Each time a company employee accesses mHealth service using M2M devices the subscription must be authenticated by the hospital.
