Abstract

A method and application server for supporting a communication established between a first mobile terminal towards a telecommunications network that includes first and second radio access networks. When a session setup is initiated with respect to the first mobile terminal, the application server receives a session identifier. The application server enters the identifier into an identifier list comprising one or more identifiers for identifying sessions with respect to the first mobile terminal. If the application server receives an indication of a session transfer from the first radio access network to the second radio access network, the application server provides the identifier list to the second radio access network in response to the indication.
