Abstract: A method is described for determining a set of coding formats usable by a first terminal to establish communications with a second terminal. The method includes obtaining, from a server, a first set of coding formats permitted on the communication network, and associated with a type of access network and with a type of communication service, and obtaining a second set of coding formats supported by the terminal, a type of access network, and a type of communication service which are used by the terminal. A third set of coding formats are determined, corresponding to a set of coding formats supported by the terminal and permitted by the network with regard to the type of network access and to the type of communication service used by the terminal, and a setup message is transmitted to the second terminal including at least one coding format included in the third set when the third set is not empty.

Abstract: The invention relates to a method for configuring a quality of service by way of a gateway including an interface on a local area network and an interface on a wide area network for a terminal of the local area network to access the wide area network, following the reception, by the gateway, of a network discovery message transmitted by the terminal, the method being noteworthy in that it comprises the steps of associating at least one address of the gateway on the local area network with a particular quality of service setting of the gateway, sending a network attachment offer message to the terminal, the message comprising at least one address of the gateway associated with a particular setting of the quality of service, and, upon reception of a message from the terminal and destined for an address of the gateway, processing the packet according to the setting associated with the destination address of the message.

Abstract: A method is proposed for configuring a terminal by using a server in an IMS communication network. The method includes: receiving an SIP registration message from a terminal, the registration message having at least one parameter relating to the access network, obtaining a configuration from the parameter relating to the access network included in the registration message received, and transmitting to the terminal a response to the registration message, the message having the configuration obtained from the parameter relating to the access network. Correlatively, a method is proposed for obtaining a configuration on a terminal.

Abstract: A method and a proxy server for selecting an input server of an IMS communication network in order to register a terminal in the IMS communication network. Following receipt from the terminal of an SIP registration message, the proxy server obtains a value of at least one field of the SIP registration message, the field being representative of a characteristic belonging to the terminal, and selects an input server using the at least one value obtained. Then, the proxy server sends, to the terminal, an SIP redirection message including an IP address of the selected input server.

Abstract: A monitoring method implemented by an access point for a network that can maintain an address association table is described. The method can include selecting at least two entries in the address association table, storing at least one predetermined characteristic obtained over a predefined period of time for each inflow and each outflow associated with the selected entries, and comparing, for at least one pair of selected entries, at least one stored characteristic for an inflow associated with one of the entries of the pair with the at least one corresponding stored characteristic for an outflow associated with the other entry of the pair. If, for at least one pair of entries, the comparison step indicates that an inflow associated with one of the entries of the pair transports an application content of the same nature as an outflow associated with the other entry of the pair, a risk of fraud can be detected.

Abstract: A method and a device for supplying location information to an apparatus connected to a network access point. The a method is implemented by a network access point, which is capable of providing the apparatus with access to a communication network to which the access point is connected when the apparatus is connected to a local network of the network access point. The network access point obtains, from a server of the communication network, information on the location of the network access point, the location information being location information certified by the operator of the communication network. The network access point receives, from the apparatus, a request for location information and sends the certified location information obtained to the apparatus.

Abstract: Devices, systems, and methods for sending and processing session initiation protocol (SIP) responses are disclosed. According to one aspect, a method for sending an SIP response through a first telecommunications network node is described. The method includes receiving, by means of the first node, a SIP request sent by means of a second node of the network. The method includes detecting an event that interferes with processing of said request by means of the first node. The method further includes sending, to the second node, a SIP response notifying said interference. The method also includes, before the sending step, activating, within the SIP response, a parameter that allows the request to be rerouted, said parameter being configurable by means of the second node.
