Abstract:
PURPOSE: A policy management system and a whole policy profile setting method thereof are provided to set a policy profile en bloc and guarantee automation and consistency. CONSTITUTION: A user request processing unit(120) takes a request for a management function of a processing object profile from a user. A profile managing unit(130) generates, amends or deletes a policy profile by equipment according to the management function of the requested profile. The profile managing unit sets en bloc a corresponding policy profile to each network element device(10) included in a selected setting range. A network element device adapter(140) performs connection for communicating with the network element devices. A profile database(150) stores information related to the policy profile.

Abstract:
A method for recognizing a policy control target equipment and controlling a hierarchical policy to offer the IP communication service and an apparatus thereof are provided to extract access network configuration information dynamically, and improve the control method for policies related to component equipments within an access network. A subscriber IP address receiver(810) receives the IP address of a subscriber terminal in which an IP packet network connection is authenticated. A path tracking unit(820) traces the path to the subscriber terminal by using the received IP address of the subscriber terminal as a destination. A equipment detecting unit(830) detects equipments comprising an access network which are connected to the subscriber terminal from the result of the path tracing. A policy control unit(840) controls IP communications service policies related to the detected equipments.
Abstract:
Provided are a method and an apparatus for periodically measuring speech quality in a voice over Internet protocol (VoIP) terminal while a VoIP call between VoIP terminals is in progress. The method comprises: receiving summary information regarding traffic sent from an opposite VoIP terminal; and evaluating speech quality by comparing the summary information with actually received information regarding the traffic sent from the opposite VoIP. Accordingly, each VoIP terminal can precisely evaluate the speech quality periodically and send the evaluation result to each other.
Abstract:
A method for processing a signaling message in an MPLS LSP based transmission network and a subscriber network supporting path-coupled signaling is provided to enhance scalability of a network by reducing a load which is added to the transmission network. A interaction supporting system is made up of a transmission network boundary router(120) and a resource management system(130). If a specified terminal(110) of a subscriber network transmits a path-coupled signaling message through a specified path(170), the transmission network boundary router connected to the subscriber network converts the message and transmits the converted message to the resource management system. The resource management system checks up the message to identify the subscriber network where a subscriber terminal(160) is located, a transmission network boundary router(140) connected with the subscriber network, and the resource management system(150). And the resource management system transmits the converted message to the identified resource management system so as to perform the path-coupled signaling on the path(190) between the boundary router and the terminal(160) of a called party.
