Embodiment Construction

[0034] attached figure 1 A transmitting terminal 10 is shown, which communicates with a receiving terminal 12 through a data transmission network 18 .

[0035] The terminals 10 and 12 are, for example, information processors or communicators, and the data transmission network 18 is a network IP 18 or a switched telephone network system combined with the network IP.

[0036] The data transmission network 18 is composed of a system of sending routers 14, 16, which are connected to each other, and its function is to ensure the correct routing of messages between the terminals 10 and 12 through the data transmission network 18.

[0037] Terminals 10 and 12 simultaneously exchange session initiation messages for exchange of multimedia streams and multimedia streams. In the following description we will consider that the initialization message is a SIP message.

[0038] These messages SIP are transmitted in packets, that is to say they are transmitted in multiple packets.

[0039...

Abstract

The invention relates to a method for monitoring messages for initiation of multimedia flow exchange sessions, whereby said messages are transmitted in packet mode via a monitoring server through a network between a transmitting terminal and at least one receiving terminal. Said method comprises a step of estimating (50) a transmission rate value for at least one initiation packet, received by the monitoring server, a step of comparing (52) said value to a maximal authorised transmission rate value and a step of enabling (40) transmission of the initiation packet, only if the transmission rate value for said packet does not exceed the maximal authorised transmission rate value. Preferably, the estimated transmission rate value is a mean value which is measured on a sliding time window. Said invention also relates to a server and an installation for carrying out the inventive method.

Description

technical field [0001] The invention relates to a message monitoring method designated for multimedia information flow exchange dialogue initialization, a monitoring (server) device and equipment using the method. Background technique [0002] More precisely, the invention relates to a message monitoring method intended for initiation of a multimedia stream exchange session transmitted in packets by a network between a transmitter terminal and at least one receiver terminal via a monitor. [0003] The term initialization can be understood as arranging, changing or aborting a session in which multimedia information streams are exchanged. [0004] Next, we will discuss the present invention based on the SIP protocol. However, the invention is not limited to this unique protocol. [0005] The protocol SIP (Session Initiation Protocol) is an OSI-mode application-layer protocol which makes it possible to arrange, change or terminate a session in which multimedia streams are exc...
