Abstract
This application provides a communication method and apparatus, and relates to the communication field, to resolve a problem that resource utilization is low because a network device cannot release a context of a terminal device in a timely manner when an SDT failure occurs, thereby improving resource utilization. The method includes: obtaining small data transmission SDT failure information; releasing an access stratum AS context of a terminal device based on the SDT failure information; and sending a first request message to a core network device. The first request message includes the SDT failure information, and the first request message is used to request the core network device to release a non-access stratum NAS context of the terminal device.
