METHOD AND APPARATUS FOR HANDLING BACKGROUND DATA TRANSFER
Document Type and Number:
WIPO Patent Application WO/2021/046676
Kind Code:
A1
Abstract:
The present application generally relates to wireless communication technology. More particularly, the present application relates to a method and an apparatus for handling Background Data Transfer (BDT) for a User Equipment (UE). The present application also relates to computer program product adapted for the same purpose. According to one embodiment, a method for handling Background Data Transfer (BDT) for a User Equipment (UE) comprises: -a) transmitting, from a node for Application Function (AF) to a node for Policy Control Function (PCF), a BDT policy request indicating the BDT is UE trajectory-relevant; and -b) at the node for AF, receiving from the node for PCF, a plurality of BDT policy groups, each of which is associated with a corresponding section of a trajectory.
