Abstract

The invention relates to a processing method, implemented by an application server (AS) capable of transmitting and receiving signalling messages via a first communication link (L1) established with a first core network (CR1). According to the invention, the processing method is suitable for obtaining, depending on a first received signalling message, a second signalling message comprising an identifier of a destination terminal, in order to determine, depending on said identifier, if the destination terminal is connected to a second core network (CR2) and to transmit the second message via a second communication link established with the second core network (CR2). The invention also relates to a method for managing a signalling message, capable of receiving, via the second link, the second signalling message, and transmitting it to the destination terminal. The invention relates to an application server (AS) and to a server (S-CSCF) of a core network (CR2) implementing the processing and managing methods respectively.

Claims

1. A communication-related processing method, implemented by an application server (AS) able to send and to receive signaling messages via a first communication link (L1) established between said application server (AS) and a first set of devices forming a first core network (CR1), characterized in that it comprises the following steps:

reception (E4), via the first communication link (L1), of a first signaling message (SG1);

obtaining (E6), as a function of said first signaling message received (SG1), of a second signaling message (SG2) comprising an identifier of a recipient terminal (ID4) receiving said second message;

analysis (E8) to determine, as a function of said recipient terminal identifier (ID4), whether said recipient terminal is connected to a second core network (CR2) of a predefined group (G) of core networks, said second core network (CR2) being different from said first core network (CR1);

in case of positive determination, transmission (E14) of said second signaling message (ID4) via a second communication link (L2) established between said application server (AS) and a second set of devices forming said second core network (CR2).

2. The processing method as claimed in claim 1, in which said recipient terminal identifier comprises an identifier of the second core network.

3. The processing method as claimed in claim 1, in which during the transmission step, said second signaling message is transmitted to a device of said second set of devices, an address of said device previously being recorded in association with said recipient terminal identifier.

4. The processing method as claimed in claim 3, in which said address is recorded by said application server following the receipt of a registration message transmitted previously by said recipient terminal.

5. The processing method as claimed in claim 1, in which said second signaling message transmitted during said transmission step comprises a processing indicator signaling that said second message has been processed by said application server.

6. The processing method as claimed in claim 1, in which said second message is said first message.

7. The processing method as claimed in claim 1, in which said second message is determined as a function of a terminal identifier contained in said first signaling message and as a function of service data previously recorded in association with a user identifier of said terminal.

8. A method for managing a signaling message relating to a communication, implemented by a server (S-CSCF) of a set of devices forming a second core network (CR2), characterized in that it comprises the following steps:

reception (E16), via a second communication link (L2) established between an application server (AS) and said server (S-CSCF), of a second signaling message (SG2) comprising a terminal identifier (ID4) for the recipient of said message, said second message having been obtained by said application server (AS) as a function of a first signaling message (SG1) received by said application server (AS) via a first communication link (L1) established between said application server (AS) and a first set of devices forming a first core network (CR1);

transmission (E18) of said second message (SG2) destined for said recipient terminal.

9. The management method as claimed in claim 8, in which said second signaling message comprises a processing indicator signaling that said message has been processed by said application server.

10. An application server (AS) comprising a first communication module (COM1) for sending and receiving signaling messages relating to a communication between two users, via a first communication link established between said application server and a first set of devices forming a first core network, characterized in that it comprises:

a module for obtaining (OBT), as a function of a first signaling message received via the first communication link, a second signaling message comprising an identifier of a recipient terminal of said second message;

an analysis module (ANL) for determining, as a function of said recipient terminal identifier, whether said recipient terminal is connected to a second core network of a predefined group of core networks, said second core network being different from said first core network;

a second communication module (COM2) for transmitting, in case of positive determination, said second signaling message via a second communication link established between said application server and a second set of devices forming said second core network.

11. A server (S-CSCF) of a set of devices forming a second core network (CR2), characterized in that it comprises:

a reception module (REC) for receiving, via a second communication link established between an application server and said server, a second signaling message relating to a communication and comprising a terminal identifier for the recipient of said message, said message having been obtained by said application server as a function of a first signaling message received by said application server via a first communication link established between said application server and a first set of devices forming a first core network,

a transmission module (TRM) for transmitting said second message destined for said second terminal.
