METHOD AND APPARATUS FOR VIRTUALIZING PRIVATE BRANCH EXCHANGE
The present invention relates to a method and an apparatus for virtualizing a private branch exchange by unifying resources of the private branch exchange into a virtual server thereby to form an internet-based (cloud) environment and using redistribution of the unified resources. A virtual system includes a virtual server configured to register terminals included in physical local system, which performs management to provide registration and services with terminal equipments included in the physical local system, and to redistribute the registered terminal equipments; and at least one virtual local system formed by redistributing the terminal equipments registered in the virtual server.
1 . A virtual system, comprising:
a virtual server configured to register terminals included in a physical local system, which performs management to provide registration and services with terminals included in the physical local system, and to redistribute the registered terminals; and
at least one virtual local system formed by redistributing the terminals registered in the virtual server.
2 . The virtual system of claim 1 , wherein the at least one virtual local system is configured to perform functions and operations identical to functions and operations of the physical local system except an emergency call function.
3 . The virtual system of claim 2 , wherein the terminals include a private branch exchange.
4 . The virtual system of claim 3 , wherein the physical system includes:
a cloud agent configured to exclusively communicate with the virtual system;
at least one gateway configured to relay networks using different protocols; and
at least one key phone client connected to a network through the private branch exchange for transmission and reception of data or messages.
5 . The virtual system of claim 4 , wherein the emergency call function is performed by using the virtual server or the cloud agent.
6 . A method for virtualizing a private branch exchange, comprising:
registering terminals included in a physical local system in a virtual server;
establishing, by the virtual server, at least one virtual local system; and
redistributing the terminals registered in the virtual server to the at least one virtual local system.
7 . The method of claim 6 , wherein the at least one virtual local system is configured to perform functions and operations identical to the physical local system except an emergency call function.
8 . The method of claim 7 , wherein the emergency call function is performed by using the virtual server or the cloud agent included in the physical local system.
