Abstract:
The present invention relates to a method of transmitting a scheduling request (SR) by a user equipment (UE) in a wireless communication system, wherein the UE is connected to a first network. In particular, the method includes the steps of: performing a random access procedure with a second network; and based on the random access procedure being successfully performed, discarding packets which are stored in a buffer for transmission to the first network.
