Abstract:
A signaling management method for managing signaling in a telecommunications network, in which, in normal operation, access equipment (21) of said network specifies a registration refresh period P to a terminal (10, 11). According to the invention, after said access equipment (21) has detected a fault affecting the network core (22) and then the access equipment (21) has received a registration refresh request from said terminal (10, 11), the access equipment (21): determines the duration R that remains for the registration in the network core (22) for the terminal (10, 11), and also determines the actual refresh period Q as implemented by the terminal (10, 11) in response to the access equipment (21) specifying thereto a refresh period equal to P; and in the event that R≧Q, the access equipment (21) sends registration confirmation to the terminal (10, 11) without relaying said request to the network core (22).

Abstract:
A method of regulating traffic in a telecommunications network, including a first step of detecting a fault affecting a node or a link of the network. The second step below is then executed: the nodes located immediately upstream of said node/link that experienced the fault forward to the latter the registration requests sent by users of the network, to the extent that the throughput of said registration requests is below a predetermined clipping threshold associated with the registration requests; if the throughput of registration requests exceeds said clipping threshold, the excess requests are not forwarded to the node/link that experienced the fault, and the network sends to each user that sent a request refused in this way, a response prompting that user to observe a time-out period, said response specifying the recommended duration of said time-out period. Application in particular to IP networks using SIP signaling protocols.
Abstract:
A method of obtaining configuration data for a terminal using the DHCP protocol. The method includes inserting optional data including an identifier into a predefined option field of a DHCP request sent by a DHCP client module to obtain configuration data, directly or indirectly, with a single user of the terminal, to obtain configuration data customized for the user.

Abstract:
The invention relates to a method of monitoring multimedia stream exchange session initialization messages transmitted in packet mode via a monitoring server over a network between a sender terminal and one or more receiver terminals. Said method comprises a step (50) of estimating a bit rate value for at least one initialization packet received by the monitoring server, a step (52) of comparing said value to a maximum authorized bit rate value, and a step (40) of authorizing transmission of the initialization packet only if the bit rate value for said packet does not exceed the maximum authorized bit rate value. The estimated bit rate value is optionally an average value that is measured over a sliding time window. The invention also relates to a server and an installation for carrying out the method of the invention.
