Provided is a method in which a management server provides wireless LAN security policy by participating in multiple APs. The method includes a step of receiving terminal information of a terminal, which is acquired in a process of scanning broadcasting information of multiple APs, from each of the multiple APs, a step of issuing and storing a token for opening a wireless LAN data channel to each of the multiple APs on the basis of reception time points of the terminal information, a step of receiving a token request for opening a wireless LAN data channel to an AP to be accessed, selected by a terminal among the multiple APs, and a step of distributing, to the terminal, a token of the AP to be accessed corresponding to the token request.

Management server, terminal, and method for providing and applying wireless LAN security policy by participating in multiple access points

Provided is a matching system including a policy and rule processing unit configured to extract SC units for each application service required, combine the SC units, configure a transaction unit, and determine an amount to be charged for a transaction according to a charging rule; a matching processing unit configured to match the extracted SC units to NC units; and an NC combination processing unit configured to combine the NC units used for the matching and deliver the combination of the NC units and detailed operating conditions to the networking management system.

Network operation system and method

Provided herein is a network access method and apparatus for supporting mobility of user equipment, the method including receiving information on a private IP (Internet Protocol) address for address conversion from a home network management server; receiving an LISP (Locator/ID Separation Protocol) data frame that includes a private IP address of the user equipment accessed to a current home network; converting the private IP address into a converted private IP address based on the information on a private IP address for address conversion; and transmitting data that has its basis on the LISP data frame to the home network apparatus based on the conversed private IP address, wherein the home network apparatus is an apparatus that the user equipment intends to access and that is accessed to the access home network.

Method and apparatus for supporting mobility of user equipment

A method and an apparatus for fairly allocating resources to network users are provided. The method for fair resource allocation to network users allows the resource allocation apparatus to collect flow information between a user terminal and a service server and aggregates the flow information based on at least one of a user terminal address, a service server address, a user terminal, a service server address, and a service. The allocation resource of the user is controlled to the predetermined recommended bandwidth by using the ratio of the aggregated flow information.

Method and apparatus for fairly allocating resource to network users

Provided are a user authentication apparatus and method for supporting PMIPv6 (Proxy Mobile Internet Protocol version 6) in next generation networks. Authentication and mobility signaling protocol can be performed without having an additional signaling process when a mobile terminal moves by extending user profiles of the next generations to support the PMIPv6.

User authentication apparatus and method for supporting PMIPv6 in next generation networks

Provided are a router and a method of controlling a maximum transmission unit (MTU) of an external network interface. The router controls the MTU by disassembling packet data segments of a predetermined size and assembling the data segments of the predetermined size into the original packet data structure when the external network interface physically included in a linecard processor has an MTU that is greater than that of an internal data communication channel of the router, so that the external network interface can transmit and receive data with another router without being affected by the MTU of the internal data communication channel in the operating system of the router.
