Description

Technical Field The present application relates to the field of communication, and more particularly to a communication method, a terminal device, and an access network device. Background In a 5G system, a Radio Access Network (RAN) paging mechanism is introduced. In this mechanism, a connection between a terminal device and a core network is maintained. When downlink data arrives, the core network sends the data to an access network. The core network pages the terminal through the access network. Specifically, paging the terminal by the core network through the access network may include RAN paging and Core Network (CN) paging. For different paging types, subsequent behaviors of the terminal device are different. For example, for the RAN paging, the terminal device needs to transit from an inactive state to an active state to receive downlink data. For the CN paging, the terminal needs to reply to the core network with a corresponding response message. Therefore, for the terminal device, how to determine a paging type of a received message is a problem worth studying. Related technologies are known from R2-1702815, US 2016/0135141 A1, US2011070900A1, CN105898894A, R2-166244, US2016070028A1, US2015365914A1 and R2-163932.
