The present invention relates to a multi-mode terminal and a driving method thereof, and more particularly, to a multi-mode terminal connected to a wireless local area network (WLAN) and a mobile communication network; It's about how.

The demand for packet data services including the Internet on the wireless mobile terminal is increasing. However, the wireless mobile terminal according to the prior art mainly provides voice calls, and is capable of transmitting only a small amount of data such as SMS (Short Message Service). Because of this, it does not meet the demand.

Accordingly, in recent years, the IMT-2000 system has been configured to increase bandwidth, improve the system structure, and start receiving packet data services such as multimedia message service and instant messenger on a wireless mobile terminal. In addition, as many communication connection methods conventionally provided by wire have recently been changed to wireless, a modem for a terminal that provides a multi-mode or more than a dual mode by using an integrated circuit (IC) technology and a software defined radio (SDR) technology. Is being developed.

However, the transmission speed is significantly lower than that of the wired environment and the wireless LAN environment. In addition, since billing is generally performed according to the amount of data, there is a significant difference in cost compared to a wired network or a wireless LAN operating at a flat rate. In addition, although the conventional wireless mobile terminal has a terminal function independently, most of them are connected to a laptop, PDA, smart phone, etc. to support a wireless connection environment.

On the other hand, the conventional wireless LAN has started to replace the wired LAN in terms of function and performance, but since there is no mobile environment such as handover and incoming calls, there are many limitations in providing a service as a mobile terminal. That is, in the case of a wireless LAN, since there is no location registration function, an incoming service cannot be received, and it can be used only in a specific area where an access point is installed, so it is difficult to provide a service as a mobile terminal.

As such, when the packet data is serviced by the wireless mobile terminal, the user does not have satisfactory performance in terms of cost and speed, and the incoming service is not provided through the wireless LAN. There are many problems in providing packet data service over the air through a mobile terminal.

The technical problem to be achieved by the present invention is to provide a wireless state management method of a multi-mode terminal to efficiently perform the function as a data terminal on the wireless mobile terminal by properly utilizing the function of the wireless communication module according to the purpose.

A driving method of a multi-mode terminal according to a feature of the present invention for achieving the above object is a driving method of a multi-mode terminal connected to a multi-radio network including a mobile communication network and a wireless LAN,
