Patent ID: 10841345

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.
