Claim 11:
12. A base station of a radio access network RAN, wherein said RAN has an interface to a core network, said base station comprising:
a wireless interface for terminal communication;
a logical inter-node interface to a further base station of the RAN;
a control unit including a data memory holding computer program code, and a processing device configured to execute the computer program code, wherein the control unit is configured to control the base station to:
detect, from 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;
receive a second message comprising data and a resume request message from the terminal, said second message indicating a pending active session associated with the terminal in a further base station to the core network;
proceed, by decision in the RAN using said indicator as a basis, to either:
- forward the received data to the further 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 base station and the core network instead of forwarding the received data to the first base station.
