As computer, electronic, and communication technologies have made rapid progress, various wireless communication services using wireless networks have been provided. The most basic wireless communication service is a wireless voice call service that provides a voice call to a mobile terminal user wirelessly, which can provide a service regardless of time and place. In addition, while providing a text message service to complement the voice call service, a wireless Internet service has recently emerged to provide an Internet communication service to a user of a mobile communication terminal through a wireless communication network. As such, the services provided by the mobile communication system are being expanded not only to voice services but also to multimedia communication services that transmit circuit data, packet data, and the like.

In order to provide such a service, a mobile communication service is an analog cellular advanced mobile phone system (AMPS) of a first generation mobile communication service, a digital cellular global system for mobile (GSM) and a CDMA of a second generation mobile communication service. Code Division Multiple Access (PCD) has developed into a Personal Communication Service (PCS), a 2.5th generation mobile communication service, and recently, the International Mobile Telecommunication 2000, a third generation mobile communication service that has been recently standardized by ITU-R. ) Is commercially available.

IMT-2000 is proposed by the 3GPP (Generation Partnership Project) as the main asynchronous WCDMA (Wideband CDMA) system and 3GPP2 as the main axis of the proposed synchronous CDMA-2000 (for example, CDMA 2000 1X, 3X, EV-DO, etc.) The system is classified and provided.

In the CDMA-2000 system, a wireless access technology and a mobile communication technology are based on the CDMA method. Therefore, since it has backward compatibility with the existing second generation IS-95 network, it is possible to provide a mobile communication service using both second and third generation communication networks. In addition, a mobile IP (Mobile Internet Protocol) function similar to a handoff (Handoff) of a voice call can be supported, and a roaming service using a Removable User Identity Module (R-UIM) card can be provided.

WCDMA system uses the CDMA method for wireless access technology, but mobile communication network technology is based on GSM network technology. The WCDMA communication method is suitable for high speed data transmission because it widens the frequency bandwidth to 5 MHz and has a data transmission rate of 2 Mbps, and the diversity according to the backward call quality that the conventional IS-95 and GSM methods cannot provide Diversity provides good call and data transmission performance even in poor communication environments.

As WCDMA communication is adopted by most countries and continues to develop technical specifications for WCDMA in 3GPP, WCDMA is also available in countries such as Korea, the United States, and China, which basically provide CDMA-2000 services. The network began to provide WCDMA services.

Meanwhile, as the wireless Internet service is activated, the demand for using the high-speed wireless Internet service in a mobile communication environment is increasing rapidly. However, the existing mobile communication system has a limitation in providing high-speed wireless Internet due to a high base station construction cost and high usage rate of the wireless Internet, and a small screen of the terminal, which limits the available content. As a result, WiBro (Wireless Broadband Internet), a high-speed portable Internet service, which guarantees portability and mobility and can use a wireless Internet service at a low price, has emerged.

WiBro service uses various types of portable mobile terminals such as laptops, PDAs, and handheld PCs to access various information and contents through internet access in indoor and outdoor stationary environments and mobile environments with walking speeds and low to medium speeds. It is a service. In addition, the WiBro system provides mobility of 60 km / h per hour, a downlink transmission rate of 24.8 Mbps, but an uplink transmission rate of 5.2 Mbps, which is an IP (Internet Protocol) based wireless data system having up-down asymmetric transmission characteristics.

The WiBro system uses the 2.3 GHz frequency band, and in order to effectively use the allocated frequency spectrum, the Duplex method uses Time Division Duplex (TDD) and the Multiple Access method orthogonal frequency division multiple access (OFDMA). / TDMA (Time Division Multiple Access) is used.

When the MM-MB terminal 200 operates in the CDMA mode, the WCDMA mode, and the WiBro mode, respectively, under the control of the AP 245, which will be described later, the modem processing the signal of the mode is initialized to the corresponding network. After that, the mode is switched to the idle state, the network is authenticated, the location registration procedure is performed, and the service of the mode is used through the call origination / reception procedure.

Here, the initialization operation refers to creating an environment for setting information required for a terminal and then transitioning to an idle state. The initialization operation consists of a system decision substate, a pilot channel acquisition substate, and a sync channel acquisition substate. Since the terminal initialization operation is well known to those skilled in the art, a detailed description thereof will be omitted.

The CDMA modem 230, the WCDMA modem 235, and the WiBro modem 240 operate independently under the control of the AP 245 without being affected by the setting state of each modem.

When the MM-MB terminal 200 is in an idle state, the AP 245 performs the CDMA modem 230, the WCDMA modem 235, and the like to perform location registration with respect to the location registration area where the MM-MB terminal 200 is located. The WiBro modem 240 transmits a control signal for requesting location registration. The CDMA modem 230, the WCDMA modem 235, and the WiBro modem 240 that have received the location registration request perform the location registration to the CDMA network 300, the WCDMA network 310, and the WiBro network 320, respectively ( S404).

Here, location registration refers to registering information such as a current location, an operation state, an identifier, a slot cycle, and the like of each terminal in the mobile communication network so that the MM-MB terminal 200 can efficiently process the incoming / outgoing call. The region in which the CDMA network 300, the WCDMA network 310, and / or the WiBro network 320 are installed is divided by location registration area and consists of a set of cells, and the MM-MB terminal 200 is currently Location registration is performed by selecting a location registration area including a location point.

When location registration is made to the CDMA network 300, the WCDMA network 310, and the WiBro network 320, the AP 245 uses the CDMA mode and the WCDMA according to a specific condition preset in the MM-MB terminal 200. The CDMA modem 230, the WCDMA modem 235, and / or the WiBro modem 240 are controlled to select an operation mode among the mode and the WiBro mode so as to use the mobile communication service of the corresponding operation mode (S406).

For example, the MM-MB terminal 200 is located in an overlay area where the CDMA network 300, the WCDMA network 310, and the WiBro network 320 are all installed, and the PS call is in the WiBro mode, the WCDMA mode, and the CDMA. When a specific condition is set to process the priority of the mode, when the MM-MB terminal 200 intends to use the PS call service, the AP 245 selects the wibro mode as an operation mode.

When the operation mode is selected according to a specific condition, the modem of the operation mode receives a control signal from the AP 245 to perform a call processing procedure and switches to a traffic state to perform call origination / reception in the operation mode (S408). ).

On the other hand, when it is necessary to switch the operation mode according to a specific condition preset in the MM-MB terminal 200, the CDMA modem 230, WCDMA modem 235 and And / or to control the WiBro modem 240 (S410).

For example, the PS call is performed by the MM-MB terminal 200 in which the specific conditions are set to process the priority of the WiBro mode, the WCDMA mode, and the CDMA mode, such as the CDMA network 300, the WCDMA network 310, and the WiBro network. When moving from the overlay area where all of the 320 is installed to the overlay area where only the CDMA network 300 and the WCDMA network 310 are installed, the WiBro mode cannot be used. The WCDMA mode is selected as the operation mode.

When the operation mode is switched according to a specific condition, the modem of the switched operation mode receives a control signal of the AP 245 to perform a call processing procedure and switches to a traffic state to perform call origination / reception in the switched operation mode. (S412).

Since the CDMA modem 230, the WCDMA modem 235, and the WiBro modem 240 of the MM-MB terminal 200 operate independently, the mobile communication service may be used in a specific operation mode while using another mode. In this case, the network switching is performed without any additional work for the modem to perform the call processing procedure to another mode, and the mobile communication service of the switched mode is used by switching to the traffic state.

As described above, the present invention can use all of the mobile communication services provided in the CDMA mode, the WCDMA mode and the WiBro mode by using the MM-MB terminal, and selects an operation mode suitable for call characteristics according to the mobile communication environment. There is an effect available.

In addition, CDMA modems, WCDMA modems and WiBro modems of MM-MB terminals operate independently without being affected by the setting state of other modems. Therefore, there is no need for additional modem operation when switching from one operation mode to another. There is an advantage that immediate operation is possible by performing network switching.
