Embodiment Construction

[0018] The present invention provides a method for quickly recovering emergency services for important user communications when a major system failure occurs in a telephone exchange end office—a simulated fault end office method: when a certain end office switch in the telecommunication exchange network fails, it becomes " In the event of a "failure office", an emergency switching device is used to replace the work of the "failure office" to quickly restore the outgoing and incoming telephone services of important users.

[0019] 1. Realization principle of simulated fault end office

[0020] figure 1 It is a schematic diagram of the telephone end office X network and user properties. Make the following data assumptions for the network office, and describe the realization principle of the simulated faulty end office based on the assumed network conditions:

[0021] Office number = XXX, intra-office user number = SSSSS

[0022] Intra-office user's phone number = XXXSSSSS

Abstract

An emergency method for quickly debugging the important failure of a telephone exchange terminal office in telecommunication network features that an emergency equipment which has the office number, signaling point code, the identities and service characteristics of important users, network lines, etc. which are same as those of the failed office, is used to repalce the terminal office in failure.

Description

technical field [0001] The present invention relates to a new communication network security technology for implementing a telephone emergency exchange system in a telecommunication network, in particular to a new emergency method for quickly recovering from a major failure of a telephone exchange end office, specifically, it is applied to a major failure in a telephone exchange end office , provide emergency communication services to quickly restore the outgoing and incoming calls of important users. Background technique [0002] With the widespread use of telephones, the communication industry provides not only products but also services to the society. For a long time, telecom operators have been seeking and building high-quality telecommunication networks. The equipment in the telephone tandem office, long-distance office, signaling network, and transmission network has adopted redundant configurations to achieve backbone network security. [0003] Due to the large numb...
