METHOD AND APPARATUS FOR CHANGING PROXIMITY SERVICE-BASED RADIO ACCESS TECHNOLOGY

摘要

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.

主权项

1. A method for changing radio access technology (RAT) of a first user equipment (UE) in a wireless communication system, comprising:
transmitting information related to a user traffic session when the first UE recognizes suspension of a packet switched service during execution of proximity service (ProSe) communication; and the first UE changing RAT to a target RAT in which PS service is not supported.
