Abstract:
A solution for routing data in a radio access network RAN including a first base station (10), a second base station (20), and a logical inter-node interface (X), wherein the first base station (10) has a pending active session to a core network (110), which session is associated with a terminal (1), while the terminal is suspended from RAN connection. A method comprises detecting a resume attempt from the terminal (1) in the second base station (20); detecting an indicator, received in the second base station (20) from the terminal (1), associated with a characteristic of data to send from the terminal (1); receiving data in the second base station (20) from the terminal (1); forwarding, dependent on said indication, the received data to the first base station (10) over the logical inter-node interface (X) for transmission in the pending active session.
