| 摘要 |
The invention refers to a method of providing a service continuity of a communication between a mobile terminal (UE) and a service node (AS) within a communications network (CN), the communication network comprising a first radio access network (RAN1), a second radio access network (RAN2) and a switching node (MSC), the switching node (MSC) initiating a transfer request towards the service node (AS), while the mobile terminal (UE) is connected to the application server (AS) over the first radio access network (RAN1), transmitting a notification to access the second Radio Access Network (RAN2) to the mobile terminal (UE), receiving a session transfer number from the mobile terminal (UE) addressing the service node (AS) to complete the session transfer, and establishing a communication channel between the mobile terminal and the application server over the second radio access network. The invention further refers to the switching node, a mobility managing node and a computer program.
