Method and gateway for connecting IP communication entities via a residential gateway

摘要

The invention concerns a method for connection to IP communication entities (Ex,pu,, Ey,pu) via a residential gateway (PZ). It consists in registering (A) the public identity (pu) of each connected terminal associated with the network address (z) of the residential gateway, so that any message should be addressed to said residential gateway (Pz) and in transferring (B) said message to all the IP communication entities connected to the residential gateway (Pz), thus permitting each of the latter to filter (C) the message and to determine whether the message is addressed to a public identity which is assigned thereto. The invention is applicable to IP terminals managed in accordance with SIP or H323 protocol.

1. A method for linking to an IP network, by way of a residential gateway, a plurality of IP communication entities to which are allocated respective public identities and which are able to implement a call control protocol, said IP communication entities, internal or external to the gateway, being connected to the latter, said method comprising:
a prior step of registering the respective public identities of said IP communication entities, each entity's public identity being associated during registration with a network address of the gateway, in such a way that a message according to the call control protocol and addressed to said public identity is transmitted to the gateway; in the event of the receipt by the gateway of a message according to the call control protocol, a step of transferring said message from the gateway to all connected IP communication entities; and after receipt of the message by a connected IP communication entity, a step of filtering of the message by said connected IP communication entity, in the course of which the connected IP communication entity determines whether the message is addressed to the public identity allocated to it.
