20100157897 | MOBILE GATEWAY APPARATUS AND METHOD OF CONNECTING IP BASED SERVICES USING THE SAME - Disclosed are a mobile gateway apparatus and a method of connecting IP based services using the same. The mobile gateway apparatus assigns identifiers to user terminals that have accessed the mobile gateway apparatus through multiple internal interfaces based on various network access standards, and selects an appropriate external interface from multiple external interfaces based on various network access standards, thereby providing IP based services Even if the user terminals and the external networks operate based on various network access standards, the mobile gateway apparatus allows IP based services to be effectively provided to the user terminals by supporting more various network access standards while ensuring higher bandwidth. | 06-24-2010 |
20110041162 | METHOD AND APPARATUS FOR PROVIDING ENVIRONMENT FOR USE OF INTERNET-BASED SERVICE - An apparatus and method for improving the convenience and efficiency of use of the Internet and providing a fundamentally new environment for use of an Internet-based service through automation of authentication for Internet-based service are provided. The apparatus includes an authentication-authorization-accounting (AAA) agent which performs network access authentication such that a user terminal can access a network that the user terminal recognizes, and which performs user authentication required for using Internet-based services according to procedures in accordance with requirements predefined for a user's purpose, wherein the Internet-based services are provided over the Internet by a contents provider. Accordingly, it is possible to reduce costs to be spent on service preparation procedures which are not necessarily related to the actual use of services, and thus the convenience and efficiency of service can be improved. | 02-17-2011 |
20120124208 | APPARATUS AND METHOD FOR TRANSMITTING CONTENTS ON A RELAY NODE BETWEEN SENDING END AND RECEIVING END - An apparatus and method for transmitting contents on a relay node disposed between a sending end and a receiving end is provided. If a content, which is identical to a content requested by a user terminal, is currently being transmitted or is in a waiting mode for content transmission, a relay node, for example, a router, disposed between a sending end and a receiving end duplicates the content and transmits the duplicated content to the user terminal, thereby reducing the work load of a service terminal and the network traffic load. | 05-17-2012 |
20120127858 | METHOD AND APPARATUS FOR PROVIDING PER-SUBSCRIBER-AWARE-FLOW QOS - A packet scheduling apparatus and method to fairly share network bandwidth between multiple subscribers and to fairly share the bandwidth allocated to each subscriber between multiple flows are provided. The packet scheduling method includes calculating first bandwidth for each subscriber to fairly share total bandwidth set for the transmission of packets between multiple subscribers; calculating second bandwidth for each flow to fairly share the first bandwidth between one or more flows that belong to each of the multiple subscribers; and scheduling a packet of each of the one or more flows based on the second bandwidth. | 05-24-2012 |
20120127859 | PACKET SCHEDULING METHOD AND APPARATUS BASED ON FAIR BANDWIDTH ALLOCATION - A packet scheduling method and apparatus which allows multiple flows that require data transmission to the same output port of a network device such as a router to fairly share bandwidth. The packet scheduling method includes calculating an expected time of arrival of a (k+1)-th packet subsequent to a currently input k-th packet of individual flows by use of bandwidth allocated fairly to each of the flows and a length of the k-th packet; in response to the arrival of the (k+1)-th packet, comparing the expected time of arrival of the (k+1)-th packet to an actual time of arrival of the (k+1)-th packet; and scheduling the (k+1)-th packet of each flow according to the comparison result. | 05-24-2012 |
20120166558 | APPARATUS AND METHOD FOR FORWARDING EMAIL - An email forwarding apparatus and method are provided. The email forwarding apparatus for an original email received from a transmitter email providing apparatus to a mobile communication terminal device in response to a request from the transmitter email providing apparatus, the email forwarding apparatus includes a data communication unit to transmit and receive information regarding an email to and from the transmitter email providing apparatus or the mobile communication terminal device; a file storage unit to store an attachment file that is attached to the original email; and a control unit to transmit to the mobile communication terminal device an email which includes access information associated with the attachment file stored in the file storage unit and/or text information contained in the original email and transmit to a receiver email providing apparatus a forwarding email which includes the attachment file stored in the file storage unit and/or remade text information. | 06-28-2012 |
20120230269 | INTEGRATED ACCESS APPARATUS FOR ALL-IP CONVERGED NETWORK - An integrated access system for All-IP converged network is provided. According to an aspect, by integrating the common factors of existing complex wireless networks to load-reduce and simplify the wireless networks and convert them using Internet access technology to thereby simplify a network architecture, integratively operating radio accesses, ensuring end-to-end quality, and providing service adaptiveness, easiness in operation, CAPEX/OPEX, and excellent service adaptiveness can be achieved. | 09-13-2012 |
20130191906 | APPARATUS AND METHOD FOR SUPPORTING PORTABLE MOBILE VIRTUAL PRIVATE NETWORK SERVICE - An apparatus and method for supporting a portable mobile VPN service are provided. The method accesses a public network to generate a security tunnel, maps the generated security tunnel and a VPN address, stands by for authentication of a mobile terminal which desires to access a VPN, authenticates a mobile terminal which desires to access the VPN, and assigns an internal address which is used in the VPN according to the authentication result. | 07-25-2013 |
