An access node (110A, 110B) of a cellular network receives a message (301, 303, 305, 308) from a further access node (110A, 110B) of the cellular network. From the received message (301, 303, 305, 308), the access node extracts topology information indicating one or more application services provided by an application service platform located at the further access node. Further, the access node (110A, 110B) stores the topology information in a topology database (180A, 180B). |
