An apparatus and method for providing Short Message Service (SMS) and Multimedia Messaging Service (MMS) over a wired telephone network are provided. In an Access Point (AP), an access module provides a wireless connection interface for wireless communication with a convergence terminal. A control module controls wireless communication and communications with the wired telephone network to provide the SMS and the MMS to the convergence terminal via the access module. A wired phone module, connected to the access module and the wired telephone network, exchanges wireless communication signals with the wired telephone network. An SMS processor, connected to the access module and the wired telephone network, processes SMS transmission and reception, and an MMS processor, connected to the access module, processes MMS transmission and reception.

Apparatus and method for providing short message service and multimedia messaging service over a wired telephone network

An apparatus and method for seamlessly providing voice and data services to a user through an access terminal in a mobile communication system including a heterogeneous service & mobility gateway (HSMG) for an interworking service between a circuit network and a packet network, and various access networks overlapping each other. The access terminal notifies the HSMG that a voice call is received, if the access terminal that accessed a packet network receives a voice call. The HSMG sends a direction request to a circuit network upon receiving the notification indicating that the voice call is received. The access terminal directs to the circuit network and registers a new location upon receiving the direction request. The HSMG sets up an incoming voice call to the access terminal after the registration of a new location.

Method and apparatus for providing voice and data services in a mobile communication system with various overlapped access networks

A system for providing communication when a mobile station moves between a wireless LAN system and a mobile communication system. A packet data service node provides a packet data service between an IP network and the mobile station when the mobile station accesses the mobile communication system. A packet control function provides the packet data service between a correspondent node connected to the IP network and the mobile station when the mobile station previously connected to the mobile communication system is connected to an access point, and provides the packet data service between the correspondent node connected to the IP network and the mobile station when the mobile station previously connected to the access point is connected to a base station system. An interworking server connected between the access point of the wireless LAN system and the packet control function of the mobile communication system.

System and method for coupling between mobile communication system and wireless local area 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.

Handoff system and method between a wireless LAN and mobile communication network

Provided is a method of cross-paging including transmitting mobile terminal location information from a mobile communication system to a heterogeneous mobile communication system after the mobile terminal location registration. The mobile communication system is then requested to page the mobile terminal according to the received information in the heterogeneous mobile communication system and, then the mobile terminal is paged. Further provided is a method of cross-paging that includes determining whether the mobile terminal has been location-registered in the mobile communication system or in the heterogeneous mobile communication system with reference to pre-registered mobile terminal location information when a mobile terminal paging request occurs in the heterogeneous mobile communication system. A cross-paging message is then transmitted from the heterogeneous mobile communication system to the mobile communication system if the mobile terminal has been location-registered in the mobile communication system and then the mobile terminal is paged.

Method of cross-paging a hybrid access terminal supporting voice service and packet data service

A data push service system and method using a heterogeneous network. The system transmits push data to a Hybrid Access Terminal (HAT) in a heterogeneous mobile communication system in which at least one circuit network overlaps with at least one packet network. The HAT can be connected to a circuit network or a packet network, and is registered in a new access network. The system includes a Packet Service & Mobility Gateway (PSMG) for acquiring access state and connection information of the HAT from the circuit network and the packet network, and generating an access network switching request upon receipt of an external request signal; and a Push Proxy Gateway (PPG) for acquiring access information of the HAT which will transmit the push data from the PSMG, and transmitting a request message to the PSMG.
