Abstract

A connection-oriented communication method between at least two communicating entities, to with a sending entity and a recipient entity connected via a telecommunication network said method comprising the following steps:

• the sending, by the sending entity, of a data flow, in the form of packets, intended for the recipient entity;
• the receiving of the data by an proxy application server placed between the entities,
• the interception by the proxy server of any control messages regarding quality of service which have been defined as potentially affecting the working order of the recipient entity,
• the transmission, by the proxy server to the recipient entity, of the data arriving from the sending entity regardless of the quality of service.

Claims

1. A connection-oriented communication method between at least two communicating entities (2, 3) to with a sending entity (2) and a recipient entity (3) connected via a telecommunication network (4) said method comprising the following steps:

the sending, by the sending entity (2), of a data flow, in the form of packets, intended for the recipient (3) entity;

the receiving of the data by an proxy application server (7) placed between the entities (2, 3),

the interception by the proxy server (7) of any control messages regarding quality of service which have been defined as potentially affecting the working order of the recipient entity (3),

the transmission, by the proxy server (7) to the recipient entity (3), of the data arriving from the sending entity (2) regardless of the quality of service.

2. A method according to claim 1, wherein the intercepted control messages are not transmitted by the server (7) to the recipient entity (3).

3. A method according to claim 1, wherein the proxy server (7) intercepts all control messages regarding quality of service.

4. A method according to claim 1, wherein the proxy server (7) intercepts a predetermined category of control messages, defined as potentially affecting the working order of the recipient entity (3).

5. A method according to claim 1, wherein the control messages are established in accordance with the RTCP protocol.

6. A method according to claim 1, wherein the control messages are established in accordance with the ICMP protocol.

7. A communication system operating in connection-oriented mode, comprising a proxy application server (7) configured to:

receive a data flow arriving from a sending communicating entity (2), intended for a recipient communicating entity (3) connected to the sending entity (2) via the telecommunications network (4),

intercept any control message regarding quality of service, defined as potentially affecting the working order of the recipient entity (3),

transmitting the data flow to the recipient entity (3), regardless of the quality of service.

8. A system according to claim 7, wherein the proxy application server (7) is configured to not transmit the intercepted control messages to the recipient entity (3).

9. A computer program product implemented on a processor, and comprising instructions to:

receive, in connection-oriented mode, a data flow arriving from a sending communicating entity (2), intended for a recipient communicating entity (3) connected to the sending entity (2) via the telecommunications network (4),

intercept any control message regarding the quality of service which may potentially affect the working order of the recipient entity (3),

transmit the data flow to the recipient entity (3) regardless of the quality of service, without transmitting the intercepted control messages.

10. A computer program product according to claim 9, comprising instructions to not transmit the intercepted control messages to the recipient entity (3).
