Abstract
Embodiments of the present disclosure relate to communication. According to embodiments of the present disclosure, if an expiration of a data inactivity timer occurs during a handover, a terminal device maintains in a RRC connected state. The terminal device releases a link with the source network device. Further, the terminal device is able to ignore the expiration of the data inactivity timer during the handover. In this way, the impact of data inactivity of the source network device is properly handled.
