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 invention relates to a method for the conditional transmission of a cellular frame by a cellular device (10) over a cellular network (11) comprising cells (111). The invention is characterised in that it comprises steps in which: the device (10) scans (S2) the network (11) in order to detect cells (111); if at least one cell (111) is detected, the device (10) determines (S202) if at least one of the cells detected belongs to a list stored in a database (BDD) of the device (10) and listing the cells in which the transmission of a cellular frame is prohibited; and if none of the cells detected belongs to the list, the device (10) determines (S203) the value of a mobility variable (M) indicating whether or not the device is authorised to transmit, and the device (10) transmits (S204) a cellular frame when the mobility variable (M) indicates that the device is authorised to transmit. The invention also relates to a device for implementing said method.

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.

Abstract: The present invention concerns the field of communication between a server and target devices not connected to a communications network. The context of use is typically the management of a fleet of devices by an operator. A generic mobile application is described, for relaying messages between these non-connected devices and a management server. This application is intended to operate on a mobile terminal hold by a person moving close to the equipment. The terminal and the equipment are provided with point to point communication means. The terminal communicates with the management server when it is located within range of a communication network. The application makes it possible to store and resend the messages between the moment when the terminal is connected to the communications network and the moment when the terminal is connected to the equipment.

Abstract: The invention proposes a GSM communication module that offers the means for the application that controls it to specify to it a set of desired criteria relating to the characteristics of the packet switching service offered by the cell. This set of criteria can be taken into account by the module at various levels. It can take them into account in the initial method for selecting a cell for connecting thereto. It can also take them into account in the method for reselecting a new cell as well in the method for monitoring the neighboring cells.

Abstract: In the field of mobile telephony and more particularly the field of so-cal led machine-to-machine communication modules, the invention aims to define a notification format for establishing an application session integrating the operator connection parameters. In this case, in the case of GPRS, this entails the name of the gateway and connection identifiers.
