AI Technical Summary
Technical Problem
In the RRC_INACTIVE state, when the UE needs to send periodic or non-periodic small data packets, the existing technology requires it to revert to the RRC_CONNECTED state to send data, which causes RNA updates to affect the transmission of small data packets.
Method used
A timer is started by receiving radio resource control signaling messages. Whether to send an update area message is determined based on whether data packets are sent via data radio bearer, thus avoiding unnecessary RNA updates and optimizing the small data packet transmission process.
Benefits of technology
This ensures the transmission of small data packets, reduces unnecessary RNA updates, and improves data transmission efficiency and system performance.

Abstract
This application discloses a method and apparatus for use in a communication node for wireless communication. The communication node receives a first message; in response to receiving the first message, it starts a first timer; it determines whether to send a second message at a first moment based on whether a data packet is transmitted via a first data radio bearer; the first message is a Radio Resource Control (RRC) signaling, the name of which includes RRC and Release, and the first message indicates a first expiration value of the first timer; the time interval between the first moment and the start action of the first timer is not less than the first expiration value of the first timer; the second message is used to determine the update of a first area; the first data radio bearer is a data radio bearer of a first cell group. This application proposes a scheme to abandon RNA updates during small data packet transmission, thereby ensuring small data packet transmission.
