Summary:A method and a system for Internet Protocol (IP) session keepalive monitoring, a home gateway and a network device are provided. The method includes: receiving, by a User Equipment (UE) or an IP edge node, a Bidirectional Forwarding Detection (BFD) message sent by a Home Gateway (HGW), in which a first discriminator field value included in the BFD message is a difference between an IP address prefix of the UE and an IP address prefix of the HGW; and monitoring, by the UE or the IP edge node, whether an IP session between the IP edge node and the UE is keepalive according to the first discriminator field value in the BFD message. "Multihop BFD" is used as a keepalive monitoring mechanism of a "Multihop IPv6 Session", thereby realizing keepalive monitoring of the "Multiple hop IPv6 Session".
