Abstract: The present invention relates to the field of systems and methods of diagnosis of apparatuses constituting a vast machine-to-machine communication network. The system proposed is based on a virtual network linking the various apparatuses so as to form a hierarchical tree. This virtual network is reliant on the network for real communication between the apparatuses. However, the topology of the virtual network is independent of that of the real network. Each apparatus includes a diagnostic agent offering local self-diagnostic capabilities. Each apparatus enables offering a state of its operation and of the operation of the entire sub-network of which it is the father. The self-diagnostic capabilities of an apparatus are implemented either locally by the apparatus, or within apparatuses of its close network environment as a function of the capabilities of the various items of equipment.

Abstract: The present invention concerns a method for controlling access by an equipment for a network of the machine-to-machine type to the resources of a cellular telephony network, said equipment comprising means for wireless communication with another equipment for a machine-to-machine network. The method is characterised in that it comprises the following steps: defining at least one so-called activity time range and at least one so-called inactivity time range, enabling the equipment to access the resources of the cellular telephony network during each activity time range, and preventing the equipment from accessing the resources of the cellular telephony network during each inactivity time range.
