1. A communication method implemented for a centralized unit, comprising:
determining whether a paging of a paged terminal device is originated from a core network node or from a radio access network node, wherein the radio access network node is a base station;
setting indication information based on the determining whether the paging of the paged terminal device is originated from the core network node or from the radio access network node, wherein the indication information is set to be identity information that is originated from the core network node when the paging is originated from the core network node, or the indication information is set to be identity information that is generated by the radio access network node when the paging is originated from the radio access network node;
in response to at least determining that the paging is originated from the radio access network node, sending, by the centralized unit to a distributed unit over an F1 interface, a paging message, wherein the paging message carries the indication information that indicates that the paging is originated from the radio access network node, and wherein the indication information is set to identity information that is generated by the radio access network node, and wherein the centralized unit and the distributed unit are included in the base station.
