<p>A method, system and device for performing keep-alive monitoring on subscriber sessions are provided, so as to reduce the keep-alive monitoring traffic of an Internet Protocol (IP) edge device in an access network, and reduce the delay of the IP edge device in processing the subscriber sessions. The method for keep-alive monitoring on subscriber sessions includes: defining at least two subscriber sessions on at least one physical line between an access node (AN) and a user equipment/customer premises equipment/residential gateway (UE/CPE/RG) as a subscriber session group, and binding the subscriber session group to a Layer 2 control (L2C) connection between an IP edge device and the AN; and performing, by the IP edge device, keep-alive monitoring on the subscriber session group by using a keep-alive monitoring mechanism of the L2C connection or using an L2C message transferred on the L2C connection.</p> |
