摘要

According to the invention, the processing is implemented by a first connecting entity (P-CSCFB) of a first core network (CN), and comprises: receiving a request to switch, to the first network (ANB), a first call placed on a second network (ANA) and including a call identifier, information on a media session associated with the call on the first network, and information representing a processing to be carried out on a media session associated with the call on the second network; identifying a second entity (P-CSCFA) of the second network connecting to the core network and through which the call on the second network passes; transmitting the call identifier and the information representing the processing to the second entity; and transferring the request to the core network with the information relating to the media session and an identifier of the call in the core network.
