Abstract: A method of controlling access to a cellular communication network, for a terminal (MT) identified by a terminal identifier (IMEI) with a subscription identified by a subscription identifier (IMSI), characterized in that it comprises the following steps: creation in a database (DB), of at least one record comprising at least one subscription identifier with at least one terminal identifier, checking that said terminal (MT) together with said subscription are indeed authorized to use the cellular communication network, by verifying the presence in the database (DB) of at least one record comprising the subscription identifier (IMSI) of said subscription associated with the terminal identifier (IMIE) said verification being performed at the time of each attempt at connection of said terminal (MT) or of said subscription, authorization of access or refusal of access of said terminal (MT) to said network according to the result of the verification step.

Abstract: The invention proposes in particular a method of managing the connectivity of a terminal connectable to a cellular communication network characterized in that it comprises the following steps carried out in the terminal: if the terminal is already connected to the network: on completion of the dispatching of messages or after a predetermined duration following the dispatching of messages, determining whether conditions of configurations required in order to maintain a connection of the terminal to the network are all satisfied, maintaining the connection of the terminal to the network and authorizing the dispatching of the messages only if the conditions of configurations required to establish a connection of the terminal to the network are all satisfied, otherwise interrupting the connection of the terminal to the network, receiving from a management module remote from the terminal a signalling message ordering a disconnection of the terminal.

Abstract: Method and system for optimizing the roaming mechanism through handling by the visited network the data that are sent by the wireless devices without routing these data to the home network. International gateways are therefore not used or are used for much fewer communications, thereby decreasing the cost of roaming for telecommunication operators. In addition, the invention allows processing in the home network the authentication and charging operation that needs sensitive information, preserving thereby the security of data.

Abstract: A Module connected through a communication network to at least a measuring mobile terminal, at least a mobile switch center and at least a machine to machine application, the module includes: a home location register configured to provide on demand, for a given measuring mobile terminal, an address of the mobile switch center through which the measuring mobile terminal is connected to the cellular communication network, an authentication center authenticating a given measuring mobile terminal, at least one short message service center configured to transmit the message towards a measuring mobile terminal, a short message service center interfaced between the cellular communication network and the machine to machine application, the home location register, the authentication center, the short message service center and the short message service center being embedded in a single physical structure forming at least in part the module.
