Abstract:
The present invention relates to a method and an apparatus for changing a radio access technology (RAT) of a terminal in a wireless communication system. More specifically, the method according to the present invention comprises the steps of: transmitting user traffic session related information when a terminal perceives that a packet switched service will be discontinued while carrying out proximity service (ProSe); and changing, by a first terminal, to a target RAT, in which PS service is not supported.
