A method and system of facilitating service delivery to a first user (A) registered with a home network (home PLMN) for a particular service having an associated announcement accessible to a service subsystem ( 4,9 ) of the home network in a communications system while the user is roaming in a visited network (visited PLMN) of the communications system. The user is identified for the home network and a connection is initiated from the first user (A) to a second user (B) registered any network of the communications system. The initiated connection is routed to the service subsystem ( 9 ) of the home network, the service subsystem ( 9 ) of the home network delivers the announcement to the first user, and the service subsystem ( 9 ) of the home network establishes a connection between the first and second user (A and B). |
