Abstract
The invention concerns a residential gateway device designed for a decentralized client equipment and comprising converting means for providing interoperability between to separate IP telephony services.
Claims20
A home gateway device intended for a decentralized client equipment, to which a network address is allocated, and comprising:
- receiving means for receiving a request for at least one address of a home gateway device able to convert data in order to provide interoperability between two given distinct IP telephony services,
- data conversion means for providing interoperability between two distinct IP telephony services, and
- sending means for sending a response to the request, said response comprising the network address allocated to the home gateway device.
(canceled)
An interoperability method intended to be used by a first home gateway device of a client equipment, comprising the following steps:
- receiving from a second home gateway device data sent in accordance with a first IP telephony service, and receiving from a third home gateway device data sent in accordance with a second IP telephony service,
- converting the data received from the second home gateway device into data in accordance with the second IP telephony service, and converting the data received from the third home gateway device into data in accordance with the first IP telephony service,
- transmitting the data converted in accordance with the second IP telephony service to the third home gateway device, and transmitting the data converted in accordance with the first IP telephony service to the second home gateway device.
A routing method for IP telephony services, comprising:
- sending a request for at least one address of a home gateway device able to convert data for providing interoperability between two given distinct IP telephony services, and
- receiving a group of responses comprising at least one response, said at least one response comprising an address of a home gateway device of a decentralized client equipment.
A routing device for IP telephony services comprising:
- sending means for sending a request for at least one address of a home gateway device able to convert data in order to allow interoperability between two given distinct IP telephony services, and
- receiving means for receiving a group of responses comprising at least one response, said at least one response comprising an address of a home gateway device.
