Title:
TERMINAL DEVICE, METHOD, AND INTEGRATED CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2019/131851
Kind Code:
A1
Abstract:
This terminal device, for communicating with one or multiple base station devices, is provided with: a receiving unit which receives from the base station device an RRC reset message that includes DRB settings, the DRB settings including a DRB identifier and an EPS bearer identifier; and a processing unit which, if the DRB identifier is not part of the present settings of the terminal device, EN-DC is configured in the terminal device, and a DRB was configured for the EPS bearer identifier prior to receiving the RRC reset message, associates an established DRB and the aforementioned EPS identifier.
