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.

Method for determining a set of encoding formats in order to establish a communication

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.

Monitoring device and method implemented by an access point for a telecommunications network

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.
