Method of implementing uplink service interface protection based on access network

Abstract

The invention discloses an access network-based method with realization of ascending business interface protection and comprises a calling user off hook which determines whether the ascending business interface corresponding to user is interrupted or not, if interrupted, an self-exchanging business treatment module is accessed to await for receiving number of the called user; the invention also comprises a calling user dial which conducts coordination analysis on number, if the called user number is accessed into the network, self-exchanging calling called flow is accessed till conversation between the calling and the called is finished; if the called user number is accessed to outside network, emergency outside calling flow is accessed to acquire any space emergency outside calling interface circuit and all of calling steps for the called user can be finished through the circuit. When the access network and the business interface of a business node go wrong, the invention can choose the access network according to the called user number, and therefore, business cannot be interrupted, reliability of the access network business is improved and business safety is guaranteed.

Description

technical field The invention relates to the field of data communication, in particular to a method for protecting an uplink service interface of an access network (gateway) (hereinafter collectively referred to as the access network). Background technique In the field of data communication, in order to facilitate network management, the service topology of the access network is generally a star structure, that is, a network structure in which an access node at the central office is connected to multiple remote devices, and the access node at the central office provides services The interface is connected with the service node of the core network; the remote device is used to provide the user terminal interface, gather the users to the central office access node, and connect the service node. For example, for the traditional access network structure, it is a network in which an OLT (the central access device of the narrowband access network) is connected to multiple ONUs (t...
