Embodiment 1

[0038] Embodiment 1, see figure 2As 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

[0039] 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

[0040] 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 Transfer the monitoring results; the IP edge device uses the L2CP connection survival monitoring mechanism or the L2C message passed on the L2C connection to monitor the subscriber session group survival. When the IP edge device receives the L2C message passed 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, or whe...

Abstract

The invention discloses a survivorship monitoring method for subscriber session, a system and a device thereof, which aims at reducing the survivorship monitoring flow rate of an IP edge device to an access network and decreasing the processing delay of the IP edge device to the subscriber session. The method comprises that at least two subscriber sessions of at least one physical circuit passing through the same AN to UE/CPE/RG are defined as a subscriber session group which is connected and bound by an L2C between an IP edge device and AN; the IP edge device carries out the survivorship monitoring to the subscriber session group by a survivorship monitoring mechanism connected by an L2CP, or by the L2C information transmitted to 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...
