摘要:
Disclosed is a method for interfacing in a communication system. The method includes receiving an event, which should be processed using information managed by a second system providing a second service, from a first system providing a first service; and performing an interface so that the second system performs an operation corresponding to the event by using the information.

A method for performing a handoff between a wireless local area network (LAN) including an access router (AR) supporting an Internet protocol (IP) routing function and a mobile communication network including a packet data service node (PDSN) connected to a base station system (BSS), for supporting the IP routing function. An access terminal (AT) detects its movement from the wireless LAN to the mobile communication network, and exchanges information for tunneling between the AR and the PDSN, with the PDSN. The PDSN sets up a tunnel for packet delivery between the PDSN and the AR, and delivers packets to the AT through the set tunnel.

A terminal-state-setting apparatus and a method using a distance between a portable communication terminal and a user are provided. The terminal-state-setting method in the portable communication terminal includes measuring a distance between the terminal and a user-distance-recognizing device using a radio communication; and setting a state of the terminal according to the measured distance value. The user does not have to manually set the terminal state through the menu setup, and the user state can be accurately reflected through a presence service.

A system and method for utilizing MS information in a communication system are provided, in which an MS, an MS information server stores MS information about the at least one MS, a content server receives the MS information from the MS information server, upon receipt of the request for the MS capability-based content service from the at least one MS and provides the MS capability-based content service using the MS information to the at least one MS, and an USI server transmits the request for the MS capability-based content service to the content server, receives the MS information from the MS information server, upon receipt of a request for the MS information from the content server, and provides the MS information to the content server.
摘要:
When a terminal moves from a WLAN network to a cellular network after being allocated an IP address from a PDSN of the cellular network, a tightly coupled interworking method and apparatus between the cellular network and the WLAN network set up a temporary tunnel between the PDSN and an AGW of the WLAN network, and after completion of the handoff from the WLAN network to the cellular network, inform the PDSN of the handoff completion from the terminal, thereby enabling fast seamless handoff without data loss. Compared with the conventional tightly coupled scheme, the proposed tightly coupled scheme can prevent the need for processing cellular signals in the WLAN network because there is no need to transmit cellular signals in a WLAN interval, especially between the terminal and the AGW.

Disclosed is a method and apparatus for providing wireless access in a broadband wireless access system. The apparatus authenticates an access terminal when an access of the access terminal located in a first network employing a first predetermined access scheme is detected, allocates a private Internet Protocol (IP) address to the authenticated access terminal, translates the private IP address into a public IP address when an access of the access terminal through the private IP address is detected, and controls that the access terminal accesses a second network employing a second predetermined access scheme through the public IP address.

A handoff method is provided between a mobile communication network including a packet data service node (PDSN), connected to a base station system (BSS), for supporting an Internet protocol (IP) routing function, and a wireless local area network (LAN) including an access router (AR) supporting the IP routing function. Upon detecting handoff to the wireless LAN, an access terminal (AT) with a contact set up to the PDSN exchanges a data packet with a correspondent node (CN) via a tunnel between the AR and the PDSN. The AT determines a user traffic state according to a transmission/reception state of the data packet, and changes the contact connected to the AT according to the user traffic state.

The system includes a first wireless network providing a wireless resource using a first wireless frequency band, a first device of a cellular network connected with the first wireless network through a wire network, and a terminal setting a tunnel with the first device of the cellular network using the wireless resource of the first wireless network and connected to the cellular network through the set tunnel to perform cell processing.
摘要:
A method for providing an Internet service based on location information of a subscriber station in a communication system. The Internet service method includes, upon receipt of a search request from a subscriber station, determining whether a network accessed by the subscriber station can support a Universal Service Interface (USI), acquiring location information of the subscriber station if the network accessed by the subscriber station can support the USI, and providing an Internet service based on the acquired location information of the subscriber station to the subscriber station.
