Description

Wired / wireless integrated service system, wired / wireless integrated mobile communication terminal, and integrated service method {FMC service system and mobile, and method

The present invention relates to a wired / wireless integrated service system, a wired / wireless integrated mobile communication terminal, and an integrated service method thereof, and more particularly, to a wired / wireless integrated service system and wired / wireless integrated service which can minimize power consumption of a mobile communication terminal in a wired / wireless integrated service environment. A mobile communication terminal, and an integrated service method thereof.

Recently, research to provide a consistent and endless service to users regardless of the type of communication network has been continuously conducted. Integrating the wired / wireless data network with the mobile communication network is called FMC (Fixed Mobile Convergence). .

At present, the distinction between voice and data is disappearing not only for users but also for communication networks due to the universalization of 3G mobile communication and multimedia communication.FMC is a mobile communication network, a wired telephone network, Bluetooth, and a wireless local area network (WLAN). It is to integrate all services for UMA (Unlicensed Mobile Access) network such as UWB (Ultra Wide Band) based on IP (Internet Protocol).

Interest in the initial FMC the 3GPP (3 ^rd Generation Partnership Project) as part of the next generation of multimedia services based on the standard of IMS (IP Multimedia Subsystem) standard in the standardization organization, indexation of UMA (Unlicensed Mobile of the conventional wired or wireless data network through the IMS Access) started from the standard.

The ultimate direction of FMC pursued by 3GPP is to link all heterogeneous networks to IP core networks (CNs) and provide integrated services through IMS, and for this, disconnection between mobile communication networks and UMA networks such as WLANs. It is a service delivery standard that does not exist and conforms to IMS Voice Call Continuity (VCC). On the other hand, as an intermediate stage of the evolution to integrated IMS, UMA-based seamless service provisioning standardization is called GAN (Generic Access Network).

There are two major FMC standards. That is, IMS VCC and UMA / GAN of 3GPP. UMA / GAN established standards in 3GPP and 3GPP2 and developed commercialization technology in the UMA Forum, which has already been applied between Bluetooth and Global System for Mobile communication (GSM) / General Packet Radio Service (GPRS). Interworking tests between / WCDMA (Wideband Code Division Multiple Access) have also been completed.

IMS VCC is a 3GPP standard to support roaming between various heterogeneous IP networks integrated based on IMS. FMC achievement through IMS VCC is premised on the introduction of IMS system into the core network. Therefore, the introduction of UMA / GAN, which can support FMC between heterogeneous networks regardless of IMS, is being made mainly by existing fixed line telephone operators that have the purpose of protecting and expanding the subscriber base through FMC.

The UMA standard deals with requirements and structure design for interworking WLAN networks with GERAN [GSM / EDGE (Enhanced Data rates for GSM Evolution) Radio Access Network]. UMA technology provides GERAN / UTRAN [Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network] mobile services access to unlicensed spectrum technologies, including Bluetooth and 802.11, and solutions based on the UMA specification provide active mobile voice between networks Connection between cells of a telephone and data session can be supported without allowing any service interference. This allows subscribers to receive continuous mobile voice and data services when switching between access networks by using UMA technology.

In the UMA service, mobile terminals connected to a broadband IP network via a UMA Network Controller (UNC) are authenticated / authorized to access GERAN voice and UTRAN data via an Unlicensed wireless network. In the cellular radio access network and the unlicensed mobile access network (UMAN), the current location information of the subscriber stored in the core network is updated in the same manner so that mobile voice and data communication are transmitted.

When a mobile communication terminal having a UMA function moves out of the range of an Unlicensed wireless network, the UNC and the mobile terminal roam to a LAN, and this roaming process is constantly the same in both networks. It happens.

When a user of a mobile communication terminal is in a voice call in a GERAN network or moves into a range of an Unlicensed wireless network while creating a UTRAN data session, a voice call and a data session are automatically handed over between the two networks.

That is, the UMA is configured in dual mode (GERAN Mode / UTRAN Mode), and a handover occurs automatically between the Unlicensed wireless network range and the GERAN / UTRAN network.

Such unlicensed mobile access (UMA) technology has been proposed to provide GERAN / UTRAN services through an unlicensed network (Bluetooth, IEEE 802.11). In addition, UMA technology provides a handover between two networks (Unlicensed network, GERAN / UTRAN), providing seamless call service and data transfer.

Meanwhile, in a general UMA technology, when a mobile communication terminal is in a WLAN region, a core network (CN) and a mobile communication terminal transmit a paging request signal and a response signal through a WLAN AP such as a WiFi access point (AP). Send and receive That is, when a paging request signal comes from the core network, the mobile communication terminal receives the paging request signal from the UNC and attempts to receive a call by sending a paging response signal corresponding thereto.

Here, paging means calling a terminal of a mobile communication subscriber according to information registered in a home location register (HLR) or a visitor location register (VLR) when an incoming call for calling a mobile subscriber occurs. Say the function.

However, in the case of the general UMA scheme as described above, when the mobile communication terminal is in an accessible WLAN region, the connection setting with the WLAN AP must be maintained at all times, resulting in excessive power consumption of the mobile communication terminal.

The present invention has been made to solve the above problems, wired / wireless integrated service system and wired / wireless integrated mobile communication terminal that can minimize the power consumption of the mobile communication terminal in an environment in which the UMA network and the mobile communication network converged, and the The purpose is to provide an integrated service method.

In order to achieve the above object, the wired / wireless integrated service system according to the present invention is a wired / wireless integrated service system for providing wired / wireless integrated services in an environment in which an unlicensed mobile access (UMA) network and a mobile communication network are converged. A UMA network registration unit that searches for a UMA network connected to a network, and registers the AP by receiving an access signal from the AP when the mobile communication terminal is wirelessly connected to an access point (AP) of the searched UMA network; A connection state determination unit determining a connection state between the mobile communication terminal and the mobile communication network connected to the UMA network; And a network controller for disconnecting the connection between the mobile communication terminal and the UMA network when the connection state between the mobile communication terminal and the mobile communication network is in an idle state.

In addition, the wired / wireless integrated mobile communication terminal according to the present invention for achieving the above object, in a mobile communication terminal that can be used in an environment in which the UMA network and the mobile communication network is fused, the UMA network connected to the core network, A UMA network connection unit for wirelessly connecting to the discovered AP of the UMA network; A connection state determination unit determining a connection state with a mobile communication network; And a connection control unit which blocks the connection of the UMA network when the connection state with the mobile communication network is idle.

Meanwhile, the wired / wireless integrated service system is a wired / wireless integrated service method executed by a wired / wireless integrated service system that provides a wired / wireless integrated service in an environment in which a UMA network and a mobile communication network are converged. Searching and receiving an access signal from the AP and registering the AP when the mobile communication terminal is wirelessly connected to the found AP of the UMA network; Determining a connection state between the mobile communication terminal connected to the UMA network and the mobile communication network; Disconnecting the connection between the mobile communication terminal and the UMA network when the connection state between the mobile communication terminal and the mobile communication network is idle; And when the call connection signal to the mobile communication terminal is received, providing a wired and wireless integrated service method comprising the step of connecting the call with the mobile communication terminal through the registered AP.

The wired / wireless integrated mobile communication terminal is a wired / wireless integrated service method executed by a mobile communication terminal that can be used in an environment in which a UMA network and a mobile communication network are converged, and searches for a UMA network connected to a core network. Wirelessly accessing an AP of the UMA network; Determining a connection state with a mobile communication network; When the connection state with the mobile communication network is idle, blocking the connection of the UMA network; And checking whether a paging message has been received, and reconnecting with the UMA network when the paging message is confirmed.

As a result, when the connection between the mobile communication terminal and the mobile communication network is idle in an environment in which the UMA network and the mobile communication network are fused, it is possible to prevent unnecessary power consumption of the mobile communication terminal. In the environment in which the mobile communication network is converged, power consumption of the mobile communication terminal can be minimized.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention. However, the embodiments of the present invention described below are provided to enable those skilled in the art to more easily understand the present invention, and the scope of the present invention is not limited to the described embodiments.

1 is a diagram schematically showing a first embodiment of a wired / wireless integrated service system according to the present invention. Referring to the drawings, the mobile communication terminal 12 has a UMA network access function, and can access the UMA (Unlicensed Mobile Access) network 10 through a wireless AP (Accpoint) 14. In addition, the UMA network 10 is connected to a core network (CN) 30 through an Internet service provider (ISP) network 20. In this case, the core network 30 includes a control unit 31 such as an unlicensed network controller (UNC), and controls the UMA network 10 connected to the ISP network 20 through the control unit 31.

In addition, the mobile communication terminal 12 may be connected to the mobile communication network 40 through the Node B (42). At this time, the mobile communication network 40 includes a Radio Network Controller (RNC) 44, and is preferably connected to the MSC 38 of the core network 30 through the RNC 44.

The mobile communication terminal 12 may include a UMTS Subscriber Identity Module (USIM) card. Since the USIM card can be separated from the UE (User Equipment; here, a mobile communication terminal), a standard interface called Cu is defined between the two.

The core network 30 includes all network components related to call control, session management, mobility management, switching in the network, and the like.

Components of the core network 30 may be divided into nodes belonging to a circuit switched (CS) area, a packet switched (PS) area, and a register area.

The circuit switched area consists of MSC, HLR, VLR, GMSC, etc., which may be physically located in the same equipment. MSC, HLR, VLR manages circuit-switched connections, and manages data security functions along with mobility management such as location update, location registration, and paging. do. In addition, GMSC serves as a path through which the circuit switched area is connected to the external network.

The packet switched area is provided through SGSN 34 and GGSN 36. The SGSN 34 manages and supports a packet switching service destined for the mobile communication network 40, and provides routing area update and location information for mobility management of the mobile communication terminal 12 provided with the packet switching service. It includes functions such as registration and calling. The GGSN 36 serves as a path connecting the packet switched area to another packet switched network such as the Internet network.

The mobile communication network 40 is connected to a CS (Circuit Switched) domain for circuit switching of the core network 30, a Packet Switched (PS) domain for packet switching, and a BC (Broadcasting) domain for a broadcast service. It may be implemented as a UTRAN (UMTS Terrestrial Radio Access Network) divided into two networks or a GSM support network.

The Node B (base station) 42 of the mobile communication network 40 serves as a physical layer and is responsible for transmitting and receiving data through an air interface. In addition, the Node B 42 sets wireless physical channels necessary for data exchange with the mobile communication terminal 12 according to the control information transmitted from the RNC 44, and converts data transmitted from the upper protocol into a wireless environment. Transmit to mobile communication terminal 12. The data received from the mobile communication terminal 12 is transferred to the upper layer protocol of the RNC 44. At least one cell is present in such a Node B 42.

The RNC 44 controls respective components in the mobile communication network 40 to dynamically allocate radio resources of the mobile communication network 40, and transfers data transmitted through the mobile communication network 40 to an appropriate node. Perform a switching function. In addition, the RNC 44 performs a function of an access point of a service for all services provided through the core network 30.

The core network 30 includes a control unit 31 such as an unlicensed network controller (UNC), a Serving General Packet Radio Service (GPRS) Support Node (SGSN) 35, a Gateway GPRS Support Node (GGSN) 36, and an MSC ( Mobile Switching Center) 37. In this case, the controller 31 may include a UMA network register 32, a connection state determiner 33, and a network controller 34.

Here, the UMA network registration unit 32 searches for the UMA network 10 connected to the core network, and the mobile communication terminal 12 wirelessly connects to the wireless AP 14 of the searched UMA network 10. When the access signal is received from the wireless AP 14, the wireless AP 14 is registered accordingly. That is, the UMA network 10 connected to the ISP network 20 has an independent Internet Protocol (IP) address, and the UMA network registration unit 32 can recognize the UMA network 10 connected through the ISP network 20. In addition, when the mobile communication terminal 12 approaches the wireless communication area of the UMA network 10, the UMA network is connected through a Bluetooth device or a wireless LAN device mounted on the mobile communication terminal 12 and the wireless AP 14, respectively. In this case, the wireless AP 14 transmits an access signal indicating that the mobile communication terminal 12 is wirelessly connected to the UMA network registration unit 32. At this time, the UMA network registration unit 32 registers the identification number of the wireless AP 14, for example, the IP address of the wireless AP 14 in response to the received access signal.

The connection state determination unit 33 determines a connection state between the mobile communication terminal 12 and the mobile communication network 40 connected to the UMA network 10. Layers of the Radio Interface Protocol (RIP) between the mobile communication terminal 12 and the mobile communication network 40 are the lower 3 of the Open System Interconnection (OSI) reference model, which is well known in communication systems. L1 (first layer), L2 (second layer), and L3 (third layer) can be classified based on the three layers, among which the physical layer belonging to the first layer has information using a physical channel. Provides an information transfer service (Radio Resource Control; RRC) layer located in the third layer serves to control radio resources between the mobile communication terminal 12 and the mobile communication network 40 Do this. To this end, the radio resource control layer exchanges RRC messages between the mobile communication terminal 12 and the mobile communication network 40.

When the radio resource control layer of the mobile communication terminal 12 and the radio resource control layer of the mobile communication network 40 are connected to each other to send and receive RRC messages, the mobile communication terminal 12 is connected to an RRC connected state. If not connected, the mobile communication terminal 12 is in an idle state.

The connection state determination unit 33 is based on the above relationship between the mobile communication terminal 12 and the mobile communication network 40, the mobile communication terminal 12 and the mobile communication network 40 connected to the UMA network 10 Judge the connection between

When it is determined that the connection state between the mobile communication terminal 12 and the mobile communication network 40 is in a dormant state, the network controller 34 blocks the connection between the mobile communication terminal 12 and the UMA network 10.

When the connection state between the mobile communication terminal 12 and the mobile communication network 40 is in an idle state, in order to reduce power consumption of the mobile communication terminal 12, the mobile communication terminal 12 receives a discontinuous reception ( By using the Discontinuous Reception (DRX) scheme, the system wakes up once every DRX Cycle Length and receives a physical channel paging indicator channel (PICH) message. However, when the mobile communication terminal 12 approaches the UMA network 10 in the area of the mobile communication network 40, the mobile communication terminal 12 moves even if the connection state between the mobile communication terminal 12 and the mobile communication network 40 is idle. The communication terminal 12 maintains a connection with the wireless AP 14 of the UMA network 40. In this case, since the period of the signal for connection between the mobile communication terminal 12 and the UMA network 40 is shorter than the period of the discontinuous reception signal between the mobile communication terminal 12 and the mobile communication network 40, the mobile communication terminal Even when the connection state between the 12 and the mobile communication network 40 is idle, the mobile communication terminal 12 consumes power for maintaining a connection with the UMA network 10. In order to prevent power consumption of the mobile communication terminal 12 in this case, the network controller 34 is a mobile communication terminal when the connection state between the mobile communication terminal 12 and the mobile communication network 40 is idle. It blocks the connection between the 12 and the UMA network 10 and transmits a physical channel PICH message for waking the mobile communication terminal 12 once every discontinuous reception period length.

The PICH channel is a physical channel used to transmit a paging indicator (PI) and has a fixed data rate of SF = 256. The PICH is always used in association with a Secondary Common Control Physical Channel (SCCPCH) to which a paging channel (PCH) transport channel is mapped.

FIG. 2 is a diagram illustrating a structure of a PICH used in the wired / wireless integrated service system of FIG. 1.

One 10 ms long PICH radio frame consists of 300 bits (b0, b1, ..., b299), of which 288 bits (b0, b1, ..., b287) are used to transmit the PI. The remaining 12 bits are DTX (Discontinuous Transmission) and are not transmitted.

On the other hand, when the use of the paging channel in the WCDMA system will be described, the system periodically transmits the PICH physical channel including the PI to the mobile communication terminal 12, the mobile communication terminal 12 is associated with the PI It periodically checks whether it is in a PICH physical channel. That is, when the mobile communication terminal 12 in the sleep mode periodically wakes up and reads the PICH physical channel, and the PI information corresponding to the mobile communication terminal 12 is transmitted to the PICH physical channel, the PCH transmission channel is mapped and transmitted. By reading the SCCPCH, the mobile communication terminal 12 may receive corresponding information. Accordingly, the WCDMA system periodically transmits a broadcast channel (BCH) for transmitting system information to the mobile communication terminal 12. Information for transmitting system information block (SIB), which is a group of information for configuring each channel and protocol using such a BCH, and for updating each system information in consideration of a constantly changing wireless situation. Is transmitted through the BCH.

In addition, when a call connection signal intended for the mobile communication terminal 12 is received, the network control unit 34 transmits a paging message to the mobile communication terminal 12 through the mobile communication network 40. In this case, the network control unit 34 transmits a PI associated with the mobile communication terminal 12 to the PICH physical channel, and the mobile communication terminal 12 periodically wakes up to read the PICH physical channel and sends a paging message to the group to which the mobile communication terminal 12 belongs. If there is, it checks the paging control channel (PCCH) and checks the paging message corresponding to it. This paging message comes down through the SCCPCH physical channel.

As the mobile communication terminal 12 checks the PICH and SCCPCH in two steps as described above, the UMA network 10 in the mobile communication network 40 consumes power of the mobile communication terminal 12 due to the reception of a paging message. Can be minimized. This is because, since the PICH is data having a very short length compared to the length of the signal transmitted and received in the UMA network 10, only a very small power is used to receive this message in the mobile communication network 10.

When the mobile communication terminal 12 receives a paging message corresponding to the mobile communication terminal 12, the mobile communication terminal 12 attempts to establish a connection with the wireless AP 14 of the UMA network 10 using the GA-CSR message. The network controller 34 connects the call to the mobile communication terminal 12 through the wireless AP 14 connected as described above.

3 is a flowchart illustrating a wired / wireless integrated service method using the wired / wireless integrated service system of FIG. 1.

Referring to the figure, the UMA network registration unit 32 searches for the UMA network 10 connected to the core network. That is, if the UMA network 10 capable of wireless communication with the mobile communication terminal 12 via Bluetooth or wireless LAN receives an IP address through the ISP network 20 and is connected to the core network 30, the UMA network The registration unit 32 searches for the UMA network 10 within the mobile communication range of the mobile communication network (S101).

In addition, when the mobile communication terminal 12 in the mobile communication network 30 wirelessly connects with the wireless AP 14 of the UMA network 10, the UMA network registration unit 32 connects from the wireless AP 14. A signal is received and the corresponding wireless AP 14 is registered accordingly (S103).

The connection state determination unit 33 determines a connection state between the mobile communication terminal 12 and the mobile communication network 40 (S105). At this time, when it is determined by the connection state determining unit 33 that the connection state between the mobile communication terminal 12 and the mobile communication network 40 is in a dormant state, the network control unit 34 controls the power of the mobile communication terminal 12. In order to reduce the consumption, the connection between the mobile communication terminal 12 and the wireless AP 14 of the UMA network 10 is blocked (S107, S109). Accordingly, the mobile communication terminal 12 stops the continuous transmission and reception of the signal with the wireless AP 14, and maintains the mobile communication network 40 by the network control unit 34 while maintaining the idle state with the mobile communication network 40. Wake up once for each DRX Cycle Length to receive the physical channel PICH message.

In such a state, when a call connection signal is received by the mobile communication terminal 12, the mobile communication terminal 12 receives a paging message corresponding to itself based on the PICH received by the network controller 34. If the paging message is received, reconnect with the wireless AP 14 of the UMA network 10, and the network controller 34 connects the mobile communication terminal 12 to the wireless AP 14 through the connection. The call to the mobile communication terminal 12 is connected (S111, S113).

Accordingly, when the connection between the mobile communication terminal and the mobile communication network is idle, even when the mobile communication terminal is connected to the UMA network, the mobile communication terminal minimizes power consumption by cutting off the connection with the wireless AP. When the incoming call connection signal is received, the call connection through the UMA network can be made quickly.

4 is a diagram schematically illustrating a second embodiment of a wired / wireless integrated service system according to the present invention. Referring to the drawings, the mobile communication terminal 112 has a UMA network access function, and can access the unlicensed mobile access (UMA) network 110 through a wireless AP (Accpoint) 113. In addition, the UMA network 110 is connected to a core network (CN) 130 through an Internet Service Provider (ISP) network 120.

In addition, the mobile communication terminal 112 may access the mobile communication network 140 through the Node B (144). At this time, the mobile communication network 140 includes a Radio Network Controller (RNC) 142, and is connected to the core network 130 through the RNC 142.

Herein, the mobile communication terminal 112 includes a UMA network connection unit 114, a connection state determination unit 115, a connection control unit 116, and a message confirmation unit 117. In this case, as described above, the mobile communication terminal 112 may include a UMTS Subscriber Identity Module (USIM) card, and the USIM card may be separated from a user equipment (here, a mobile communication terminal). The core network 130 also includes a UNC 131, an SGSN 133, a GGSN 135, and an MSC 137.

The UMA network connection unit 114 includes a wireless communication device such as Bluetooth or WLAN to wirelessly transmit and receive data with the wireless AP 113 of the UMA network 110, and the mobile communication terminal 112 includes the UMA network 110. If approaching within the wireless communication range of the), the wireless AP 113 that can communicate is searched for and connected wirelessly.

The connection state determination unit 115 determines a connection state with the mobile communication network 140. As described above, the layers of the Radio Interface Protocol (RIP) between the mobile communication terminal 112 and the mobile communication network 140 are known as Open System Interconnection (OSI). Based on the lower three layers of the reference model, L1 (first layer), L2 (second layer), and L3 (third layer) may be divided into physical layers belonging to the first layer. An information transfer service using a channel is provided, and a Radio Resource Control (RRC) layer located in a third layer is provided between the mobile communication terminal 112 and the mobile communication network 140. It controls the resources. To this end, the radio resource control layer exchanges RRC messages between the mobile communication terminal 112 and the mobile communication network 140.

When the radio resource control layer of the mobile communication terminal 112 and the radio resource control layer of the mobile communication network 140 are connected to exchange RRC messages with each other, the mobile communication terminal 112 is connected to the RRC connected state. If not connected, the mobile terminal 112 is in an idle state.

The connection state determination unit 115 is based on the above relationship between the mobile communication terminal 112 and the mobile communication network 140, the mobile communication terminal 112 and the mobile communication network 140 connected to the UMA network 110. Judge the connection between

When it is determined that the connection state between the mobile communication terminal 112 and the mobile communication network 140 is in a dormant state, the access control unit 34 may reduce the power consumption of the mobile communication terminal 112. And connection of the UMA network 110.

Accordingly, the mobile communication terminal 112 receives a physical channel paging indicator channel (PICH) message by waking up once for each discontinuous reception cycle length (DRX Cycle Length) using a discontinuous reception (DRX) scheme. The PICH channel is a physical channel used to transmit a paging indicator (PI). Since a detailed description thereof is as described above, the description thereof is omitted.

The message checking unit 117 checks whether there is a paging message corresponding to the group to which the group belongs based on the PICH message received through the mobile communication network 140. If there is a paging message corresponding to the group to which the group belongs through the PICH message, the message checking unit 117 checks the PCCH message to determine whether there is a paging message corresponding to the group. This message is received through the SCCPCH physical channel of the mobile communication network 140.

When the paging message corresponding to the message is confirmed by the message checking unit 117, the access controller 116 controls to reconnect to the wireless AP 113 of the UMA network 110 using the GA-CSR message.

The core network 130 includes all network components related to call control, session management, mobility management, and switching in the network.

Components of the core network 130 may be divided into nodes belonging to a circuit switched (CS) area, a packet switched (PS) area, and a register area.

The circuit switched area consists of MSC, HLR, VLR, GMSC, etc., which may be physically located in the same equipment. MSC, HLR, VLR manages circuit-switched connections, and manages data security functions along with mobility management such as location update, location registration, and paging. do. In addition, GMSC serves as a path through which the circuit switched area is connected to the external network.

The packet switched area is provided through the SGSN 133 and the GGSN 135. The SGSN 133 manages and supports a packet switching service destined for the mobile communication network 140, and provides routing area update and location information for mobility management of the mobile communication terminal 112 provided with the packet switching service. It includes functions such as registration and calling. The GGSN 135 serves as a path connecting the packet switched area to another packet switched network such as the Internet network.

The mobile communication network 140 is connected to a CS (Circuit Switched) domain for circuit switching of the core network 130, a Packet Switched (PS) domain for packet switching, and a BC (Broadcasting) domain for a broadcast service. It may be implemented as a UTRAN (UMTS Terrestrial Radio Access Network) divided into two networks or a GSM support network.

5 is a flowchart illustrating a wired / wireless integrated service method by the mobile communication terminal of FIG. 4.

Referring to the drawings, the UMA network connection unit 114 of the mobile communication terminal 112, when the mobile communication terminal 112 approaches the wireless communication range of the UMA network 110, it searches for a wireless AP 113 that can communicate The wireless connection is made (S201).

The connection state determination unit 115 determines a connection state between the mobile communication terminal 112 and the mobile communication network 140 (S203). At this time, if it is determined by the connection state determining unit 115 that the connection state between the mobile communication terminal 112 and the mobile communication network 140 is in a dormant state, the connection control unit 116 is the power of the mobile communication terminal 112 In order to reduce the consumption, the connection between the mobile communication terminal 112 and the wireless AP 113 of the UMA network 110 is blocked (S205 and S207).

Accordingly, the mobile communication terminal 112 stops transmission and reception of the continuous signal with the wireless AP 113, and maintains the mobile communication network 140 by the access controller 116 while maintaining the idle state with the mobile communication network 140. Through the wake-up for each DRX Cycle Length, a physical channel PICH message is received. Here, the connection state determination unit 115 determines a connection state between the mobile communication terminal 112 and the mobile communication network 140 after the wireless connection between the mobile communication terminal 112 and the wireless AP 113 is made. Although it was described as blocking the connection between the mobile communication terminal 112 and the wireless AP 113 according to the result, when the mobile communication terminal 112 approaches the communication area of the UMA network 110, the mobile communication terminal 112 ) And first determine a connection state between the mobile communication network 140, and when the connection state is idle according to the result, the connection between the mobile communication terminal 112 and the wireless AP 113 may not be made. It may be.

In such a state, when a call connection signal is received on the mobile communication terminal 112, the message checking unit 117 of the mobile communication terminal 112 receives a paging message corresponding to itself based on the received PICH. Check (S209).

If the message checking unit 117 confirms that the corresponding paging message has been received, the access control unit 116 reconnects with the wireless AP 113 of the UMA network 110, and the UNC 131 performs mobile communication. Through the connection of the terminal 112 and the wireless AP 113 is connected to the call to the mobile communication terminal 112 (S211, S213).

Thus, when the connection between the mobile communication terminal and the mobile communication network is idle, even if the mobile communication terminal is connected to the UMA network, the connection with the wireless AP is blocked, thereby minimizing power consumption of the mobile communication terminal. When the incoming call connection signal is received, the call connection through the UMA network can be made quickly.
