1. Method for routing data in a radio access network RAN including a first base station, a second base station, and a logical inter-node interface, wherein the first base station has a pending active session to a core network, which session is associated with a terminal, while the terminal is suspended from RAN connection, comprising
detecting, by receiving in the second base station a first message comprising a random access message from the terminal, an indicator that indicates that an amount of data to be sent from the terminal does not exceed a predetermined threshold;
receiving, in the second base station, a second message comprising data and a resume request message from the terminal;
proceeding, by decision in the RAN using said indicator as a basis, to either:
forward the received data to the first base station over the logical inter-node interface for transmission in the pending active session without making a path switch, or
make a path switch for transmitting the data over an interface between the second base station and the core network instead of forwarding the received data to the first base station.
