Embodiment 1

[0047] Embodiment 1, see figure 2 As shown, a subscriber session group is defined as at least two of multiple (at least two) physical lines (including wired or wireless lines) to UE (also customer premises equipment CPE or user gateway RG) passing through the same AN Subscriber session, the subscriber session group is bound to an L2C connection between an IP edge device (BNG / BRAS) and the AN; the IP edge device (BNG / BRAS) uses the L2CP connection survival monitoring mechanism, or passes it to the L2C The L2C message on the connection monitors the survival of the subscriber session group. When the IP edge device detects an abnormality between the BNG / BRAS and the AN through the survival monitoring mechanism of the L2CP connection, or does not receive the L2C message delivered by the AN within a predetermined time , it is detected that the subscriber session group is abnormal.

Embodiment 2

[0048] Embodiment 2, see image 3 As shown, a subscriber session group is defined as at least two subscriber sessions on a physical line (including wired or wireless lines) from AN to UE (or CPE), and the physical line is connected with an IP edge device (BNG / BRAS) Bind the L2C connection with the AN, and bind the subscriber session group with the L2C connection; the AN uses the OAM loop test on the physical line to monitor the survival of the subscriber session group, and through the L2C connection, to The L2C message transmits the monitoring result to the IP edge device; the IP edge device uses the survival monitoring mechanism of the L2CP connection, or the L2C message passed on the L2C connection to monitor the survival of the subscriber session group, when the IP edge device receives within a predetermined time When the L2C message delivered to the AN, and the monitoring result carried by the L2C message indicates that the physical line is abnormal, the subscriber session...

Embodiment 3

[0049] Embodiment 3, see Figure 4 As shown, a subscriber session group is defined as at least two subscriber sessions on a physical line (including wired or wireless lines) from AN to RG, which is connected to a L2C between an IP edge device (BNG / BRAS) and AN Bind the connection, and bind the subscriber session group with the L2C connection; AN uses the OAM loop test on the physical line to monitor the survival of the subscriber session group, and sends an L2C message to the IP edge device through the L2C connection Deliver the monitoring results; the IP edge device uses the L2CP connection survival monitoring mechanism, or the L2C message transmitted on the L2C connection to monitor the subscriber session group survival, when the IP edge device receives the L2C message delivered by the AN within a predetermined time , and the monitoring result carried in the L2C message indicates that the physical line is abnormal, then the subscriber session group is detected to be abnormal...

Abstract

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.

Description

technical field [0001] The present invention relates to the communication field, in particular to a subscriber session survival monitoring method, system and device. Background technique [0002] In order to support new services, the access network needs to add control functions to the devices of the access network, and requires the operation support device to control each device connected to the network. [0003] In the access network, an IP session (session) represents a network access connection session associated with a subscriber (Subscriber) or user (User) IP address, [0004] IP Session is equivalent to PPP (Point-to-Point Protocol) Session, a point-to-point link layer protocol. Subscriber Session is a general term for IP Session and PPP Session. Subscriber Session is usually terminated on an IP edge device (IP Edge device) (in the embodiment of the present invention, BNG broadband network gateway / broadband access server BRAS is taken as an example), that is, a Subsc...
