Method and device for guaranteeing small data transmission during a radio access network (ran) update

Abstract

The present application discloses a method and a device in a communication node for wireless communications. A communication node receives a first message; and as a response to the action of receiving a first message, starts a first timer; and determines whether to transmit a second message at a first time according to whether a packet is to be transmitted via a first data radio bearer; the first message is an RRC signaling, where a name of the first message includes RRC and Release, the first message indicating a first expiration value of the first timer; a time interval from the first time to the starting action of the first timer is no smaller than the first expiration value of the first timer. The present application proposes a scheme of canceling the performance of RNA update in Small Data transmission for guaranteeing the transmission of small data packets.
