Embodiments of the present invention provide a method, a device, and a system for supporting content subscription in a content network. The method includes: receiving, by a content network node, a first interest packet from a UE, where the first interest packet includes a first content identifier, and the first content identifier is used to indicate content to be subscribed to by the first interest packet; when a PIT has no first subscription entry corresponding to the first content identifier, creating, by the content network node, the first subscription entry, so that a subscription request through a first port represented by a first port number and corresponding to the first content identifier is valid within a first valid duration; forwarding, by the content network node, the first interest packet to another forwarding node, so that the other forwarding node sends multiple data packets to the content network node within the first valid duration; and forwarding, by the content network node, the multiple data packets to the UE. The embodiments of the present invention can reduce the number of interest packets in a content network, thereby reducing network signaling overhead. |
