US 6,650,749 B1 · Method and system for protecting equipment and switching functionality in a telecommunication system

Abstract

The present invention relates to a method and system for protecting equipment and switching functionality in a telecommunication system, which system comprises a central processor and regional processors, one or more of which is/are standby processor(s), and in order to avoid that the system configuration set by command is changed if protection switching occurs, and in order to provide a flexible concept that allows different types of protection switching methods, there is according to the present invention suggested a solution by introducing a protection group between the existing client(s) and server layers (i.e. switching network terminals), said protection group administering which server units should be working (active) and which should be standby units.

Dependent claims

A method of protecting equipment and switching functionality in a telecommunication system having a plurality of servers serving a plurality of clients, wherein at least one server among the plurality of servers is a standby server, and the other servers are working servers, the method comprising the steps of:

connecting a protection group between the plurality of servers and the plurality of clients, said protection group including a multiplex switching section for connecting any one of the plurality of clients to any one of the plurality of servers, a status monitoring section for monitoring the operational status of each of the plurality of servers, and a configuration section for storing information regarding which servers are capable of serving each of the clients;
determining by the status monitoring section that a working server has failed;
selecting by the configuration section, a standby server that is capable of serving the clients that were being served by the failed server;
and
switching by the multiplex switching section, the clients that were being served by the failed server to the selected standby server.

2 more elements

A system for protecting equipment and switching functionality in a telecommunication network, the system comprising:

a plurality of client devices for providing telecommunication services;
a plurality of servers serving the plurality of client devices, at least one server among the plurality of servers being a standby server, and the other servers being working servers;
and
protection group means connected between the plurality of client devices and the plurality of servers, said protection group means comprising:
a multiplex switching section for connecting any one of the plurality of client devices to any one of the plurality of servers;
a status monitoring section for monitoring the operational status of each of the plurality of servers;
and
a configuration section for storing information regarding which servers are capable of serving each of the client devices,
wherein upon determining by the status monitoring section that a working server has failed, the configuration section selects a standby server that is capable of serving the client devices that were being served by the failed server, and the multiplex switching section switches the client devices that were being served by the failed server over to the selected standby server.
