Problems solved by technology

However, according to the techniques disclosed in Documents 1 and 2, the boosting of the priority of the voice packet itself involves setting this condition statically in the network element, and this condition cannot be set for each call
[0013] In addition, the technology disclosed in Document 3 has a scheme to dynamically change the network policy (the policy change is to limit the traffic on the network), and still cannot perform call-by-call (call-by-call) in consideration of source / destination information and user information. by-call) priority control
[0014] Therefore, an inherent problem arises in the existing VoIP network system in which a voice communication service requiring flexible value-added call-by-call cannot be implemented without increasing operating costs

Abstract

A VoIP network system includes a module controlling a transmission of a priority control indication corresponding to a call control signal for every call and to priority control information preset for providing a VoIP-based voice communication service in a way that specifies a priority control target call related to a specified voice session, and a module giving a priority control indication about a voice packet of the priority control target call to each of network elements, configuring an IP network, for forwarding the voice packet.

Description

technical field [0001] The present invention relates generally to a VoIP (Voice over Internet Protocol) network system for forwarding (including sending and exchanging) voice packets over an IP (Internet Protocol) network, and more particularly to a system for communicating with specific voice sessions through priority control Related calls come to the VoIP network system that provides value-added services. Background technique [0002] In recent years, local and medium and long-distance telecom operators (communication service providers) have faced fierce competition for subscribers, and it is essential for them to reduce equipment / operation costs and provide attractive value-added services. [0003] First of all, each telecom operator plans to realize the above conditions by reducing equipment / operation cost by utilizing IP network based on VoIP technology as voice and data integrated network. [0004] As described below, the VoIP network system that each telecom operator...
