Abstract: A paging method and apparatus for minimizing power consumption under a heterogeneous wireless network environment is provided. The terminal can recognize data reception from the heterogeneous network using a CDMA2000 network having a wide service range under a heterogeneous wireless network environment terminal, and can open only necessary network interfaces at a predetermined time.

Abstract: A portable terminal and a method for providing network contents using the portable terminal are provided. The portable terminal receives contents from a network, uses information related to a destination and a pre-stored map data to search for a travel route from a start point to the destination, determines an estimated time for a user to reach the destination from the start point, and outputs travel guide information to guide the user along the travel route while outputting contents having a reproduction time corresponding to the estimated time.

Abstract: In a heterogeneous wireless network system, a apparatus for notifying a mobile station of existence of traffic from a network to which the mobile station is not connected receives an identifier of the mobile station from the network to which the mobile station is not connected. The apparatus checks the network to which the mobile station having the same identifier as the received is connected, and transmits a signal for indicating existence of traffic to the mobile station by using the network's interface.

Abstract: The present invention relates to a binding update identifier sub-option field configuration method and a binding update information configuration method. In the method, a binding update identifier sub-option field including current used interface and data characteristics and corresponding to one interface of the plurality of interfaces is generated, the binding update identifier sub-option field is transmitted to a home agent and a correspondent node, a care-of address corresponding to a binding update identifier is stored, and binding update is performed.

Abstract: An interworking network system between heterogeneous networks and a vertical hand-off method for supporting QoS are provided. WLAN (Wireless Local Area Network) and Wibro (Wireless Broadband) have a service range overlaid with that of the CDMA (Code Division Multiple Access) 2000 that has been provided over the whole area, and routers of the respective networks are hierarchically connected by setting the CDMA 2000 as a higher network, the WiBro as a middle network, and the WLAN as a lower network according to service area and transmission speed of the respective networks. Accordingly, a hierarchical interworking method has been provided as an integrating network of the CDMA 2000, WiBro, and WLAN independently providing a service so that it may minimize packet loss and delay.

Abstract: Methods for performing origination and termination processes to control reserved semi-permanent virtual path connections in an asynchronous transfer mode virtual path switching system. A service can flexibly be provided based on semi-permanent virtual path connection information for a desired time in response to a reserved semi-permanent virtual path registration command received through an operator interface during the operation of the system. Also, the reserved semi-permanent virtual path connections can be controlled up to 256 per subscriber link of 155 Mbps class. A subscriber service using time is designated and resources in a network are occupied only for the designated time. Therefore, a plurality of subscribers are set at different service time zones in such a manner that the network resources can be utilized at the maximum at each service time zone.
