Abstract: This application relates to a communication method and system. A first network element receives information about downlink data from a second network element, where the downlink data is from a core network device. The first network element is a first DU, and the second network element is a first CU; or the first network element is a first CU-CP, and the second network element is a first CU-UP. If the downlink data meets a downlink small data transmission condition, the first network element sends a paging message that indicates a terminal device to initiate a downlink small data transmission procedure. For example, the first network element is a DU, and the downlink data from the core network device may reach a CU.

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.

Abstract: This application relates to a communication method and device. A terminal device sends first data to an access network device on a first resource, and starts a first timer, where the first resource is a preconfigured resource, the first data is small data, and the terminal device is in an RRC non-connected state. If first information is received before the first timer expires, the first timer is stopped, where the first information is information indicating that the first data is successfully transmitted, and the first information is MAC layer information, or the first information is information for scheduling a resource. If the first information is, for example, the MAC layer information, feedback information at a physical layer does not need to be introduced.

Abstract: The present disclosure provides a communication node for operation as a part of a distributed base station entity in a communication system, the communication node being configured to, on establishment of a small data transmission communication session by a user equipment communicating with the distributed base station entity: receive from another part of the distributed base station entity a first message indicating assistance information for the session; and after traffic data has been transferred during the session, make a decision as to whether to terminate the session in dependence on the content of the first message.
