An apparatus and method are provided for changing network interfaces in a multiaccess mobile terminal in a wireless communication system including a server for providing high-capacity data transmission service to a mobile terminal, and the terminal for receiving data from the server and supporting various network interfaces. Upon detecting handoff based on current air information received, an interface module reports a change in interface to a new air interface to an upper layer, and manages the mobile terminal such that traffic is transmitted to the new air interface. Upon receiving information on the new air interface from the interface module, a service module determines a bandwidth of the new air interface, generates a message based on the determined bandwidth, and transmits the generated message.

Apparatus and method for changing network interfaces in a multiaccess mobile terminal

A method of providing Location Services (LCS) over an Internet Protocol Multimedia Subsystem (IMS) network in a wireless communication system is provided. An LCS client transmits a service connection request message including a message requesting the location information of a User Equipment (UE). The UE transmits the location information to the LCS client.

Method of providing location service over IMS network

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.
