In step <NUM>, when uplink data to be transmitted to a base station are detected, the uplink data are saved in a designated buffer.

According to an embodiment herein, UE is in an inactive state.

When uplink data to be transmitted to a base station are detected, the UE first saves the uplink data in the designated buffer.

The designated buffer may be a buffer of the UE per se.

In step <NUM>, when RLAU is started, the uplink data in the designated buffer are read.

In step <NUM>, the uplink data are transmitted to the base station in request signaling corresponding to the RLAU. The base station may then receive the request signaling and acquire the uplink data in the request signaling.

According to an embodiment herein, request signaling corresponding to RLAU may be request signaling sent by UE to a base station. The request signaling is random access request signaling sent by UE to a base station. As a mere illustration which is not part of the invention, the request signaling may be Radio Resource Control (RRC) connection recovery request signaling sent by UE to a base station.

As shown in <FIG>, an illustrative scene includes a base station and UE. As a mere illustration which is not part of the invention, UE transmits uplink data to a base station, for example through RRC connection recovery request signaling.

With the embodiment, having detected uplink data to be transmitted to a base station, UE first saves the uplink data in a designated buffer. Then, while starting RLAU, the UE reads the uplink data in the designated buffer.
