Title:
METHOD, APPARATUS AND COMPUTER PROGRAM FOR SUPPORTING A SESSION IDENTIFIER IN CASE OF A TRANSFER BETWEEN DIFFERENT RADIO ACCESS NETWORKS
Document Type and Number:
WIPO Patent Application WO/2009/130042
Kind Code:
A3
Abstract:
The invention refers to supporting a communication established between a first mobile terminal (18) towards a telecommunications network (1), the telecommunications network (1) comprising a first radio access network (13) and a second radio access network (14) and an application server (10), wherein the application server performs the steps of receiving an identifier that a session setup was initiated with respect to the first mobile terminal (18), wherein the identifier is adapted to identify the session, entering the identifier into an identifier list comprising one or a plurality of a identifiers for identifying sessions with respect to the first mobile terminal (18), receiving an indication of a session transfer form the first radio access network (13) to the second radio access network (14) or vice versa, and providing the identifier list in response to the indication. The invention further refers to an application server (10) and corresponding computer program.
