Abstract:
In order to provide an offline-based social network service from a social network service system to a plurality of terminals, an online history identifier corresponding to an offline event is transmitted to a first terminal when an online history identifier creation request message is received from the first terminal that creates the offline events among the plurality of terminals. a participant registration confirming message is transmitted to the first terminal when information on a participant list including a second terminal is received from the first terminal, and the created online history identifier is transmitted to the second terminal, thereby providing the offline-based social network service to the first terminal and the second terminal.

PURPOSE: A QoS(Quality of Service) providing method according to subscriber recognition flows is provided to enable subscribers to equally use a network band between flows by scheduling packets of one or more flows based on bandwidth. CONSTITUTION: An apparatus calculates each first bandwidth of plural subscribers for enabling the subscribers to share the established bandwidth for transmitting packets(110). One or more flows included in each subscriber calculate second bandwidths for each flow in order to equally share the first bandwidth(120). The apparatus schedules the packets of one or more flows based on the second bandwidth(130).
Abstract:
PURPOSE: A method for supporting mobility is provided to support the mobility by expanding the shortest path routing protocol to a mobile router. CONSTITUTION: A mobile router(111) generates an area identifier for identifying the shortest path priority area. The mobile router generates the area identifier by using an own identifier. The mobile router transmits routing information in which the area identifier is included to an access router(110). The shortest path priority area is the area including the mobile router and access router. The routing information is transmitted through a virtual link passing through the access router.
Abstract:
PURPOSE: A QoS profile determining method and an apparatus thereof about data traffic flow are provided to extract a QoS profile of a flow from a QoS profile of a preset flow according to the obtaining of a QoS profile. CONSTITUTION: If a first packet of a flow is inputted, a flow information block is generated. If there if opposite flow, QoS(Quality of Service) profile information of an opposite flow information block is extracted. The flow information block is updated based on the extracted information. A QoS process is performed based on the update information.
