Standalone) system. Although FIG. 1 illustrates an environment in which two radio access networks, that is, an LTE radio access network and a 5G radio access network, are mixed, various radio access networks such as a 3G radio access network may be additionally mixed.

In the 5G NSA system according to an embodiment as shown in FIG. 1, a Long Term Evolution (LTE) radio access network including an eNB 120 and a 5G radio access network including a gNB 130 are mixed. A control plan (control signal) between the 110 and the EPC 140 is transmitted using the eNB 120, and a user plan between the terminal device 110 and the EPC 140 is included. ) Transmits using the eNB 120 or gNB 130.

In addition, the terminal device 110 registers its location information with the EPC 140 through the eNB 120 in the LTE radio access network, in which case the eNB supports the 5G service.

As a result, a signal related to synchronization between the gNB 130 and the terminal device 110 is transmitted to the terminal device 110. For example, the gNB 130 transmits system information such as a master information block (MIB) and a system information block (SIB) to perform frequency synchronization and time synchronization with the terminal device 110 at any time from the 5G radio access network. You can prepare to process the data being transferred.

In addition, the terminal device 110 may output, as visualization information, information indicating that the terminal device 110 is communicating through the 5G radio access network while transmitting data through the gNB 130 in the 5G radio access network. For example, the terminal device 110 outputs an icon representing the 5G radio access network in a first form to inform that it can communicate through the 5G radio access network, and then informs that it is communicating through the 5G radio access network. The icon representing the 5G radio access network may be changed to the second form and output.

For example, the control unit 113 camps on a suitable cell based on the SIB information of the eNB 120 and registers a location while the terminal device 110 registers EN as a technical standard for 5G service based on NSA. If -DC is supported, "NR" or "EUTRA-NR" may be described as RAT type information in the terminal capability field included in the access request message.

In addition, the control unit 113 receives information related to the use of the 5G radio access network transmitted from the eNB 120 by the communication unit 111 (eg, the 5G radio access network in the RRC connection reconfiguration message received from the eNB 120). Information about the use of the 5G radio access network transmitted from the gNB 130 (e.g., system information such as MIB and SIB is received from the gNB 130). If received, etc.), the display unit 112 controls to visualize and output information indicating that communication is possible through the 5G radio access network including the gNB 130. For example, when the control unit 113 visualizes and outputs information that can be communicated through the 5G radio access network, the display unit 112 further outputs the information that communication is possible through the location-registered LTE radio access network as visualization information. Can be controlled. For example, the display unit 112 may control to simultaneously output an icon representing the LTE radio access network and an icon representing the 5G radio access network. In addition, the control unit 113 causes the display unit 112 to output, as visualization information, information that the communication unit 111 is actually communicating through the 5G radio access network while transmitting data through the gNB 130 in the 5G radio access network.

3 is a flowchart illustrating a method of outputting information related to a radio access network in a terminal device 110 according to an embodiment of the present invention. According to the flow illustrated in FIG. 3, an information output method performed by the terminal device 110 illustrated in FIGS. 1 and 2 will be described.

First, the terminal device 110 operating in the 5G NSA system must register the location on the LTE network. That is, even if the location is located in the region that can receive the 5G service, it should basically register the location in the EPC through the LTE radio access network including the eNB (120).

To this end, the control unit 113 of the terminal device 110 controls the communication unit 111 to discover the LTE radio access network (S210), eNB 120 of the appropriate cell included in the LTE radio access network is discovered and When the capability of the 5G service supports the 5G service, the communication unit 111 is controlled to transmit information indicating that the 5G radio access network is available to the eNB 120 (S220). For example, the control unit 113 camps on a suitable cell based on the SIB information of the eNB 120 and registers a location while the terminal device 110 registers EN as a technical standard for 5G service based on NSA. If -DC is supported, "NR" or "EUTRA-NR" may be described as RAT type information in the terminal capability field included in the access request message.

Here, the eNB 120 recognizes that the terminal device 110 can receive 5G service through the 5G radio access network by receiving information indicating that the 5G radio access network is available from the terminal device 110. Information related to the use of the 5G radio access network is transmitted to the terminal device 110. For example, eNB 120 may include the NR and EN-DC configuration information in the RRC connection reconfiguration message and transmit as radio link setup information for the 5G radio access network. As such, since the eNB 120 transmits radio link configuration information for the 5G radio access network, since there is an interface for exchanging control information and user data with the gNB 130 located in an adjacent area, the eNB 120 transmits 5G radio access under certain conditions. This means that you are ready to transmit data over the network.

Then, the communication unit 111 of the terminal device 110 receives information related to the use of the 5G radio access network from the eNB 120 (S230), and the control unit 113 may receive the 5G service from the terminal device 110. It is recognized that there is a state, that is, a state capable of communicating through a 5G radio access network including the gNB (130).

Meanwhile, the terminal device 110 may receive information related to the use of the 5G radio access network from the gNB 130 and recognize that communication is possible through the 5G radio access network. The controller 113 controls the communication unit 111 after completing location registration or at the same time as location registration, and performs cell searching to synchronize with the gNB 130. In this process, the gNB 130 performs a 5G radio access network. The signal related to the synchronization between the gNB 130 and the terminal device 110 is transmitted to the terminal device 110 as information related to the use of. For example, the gNB 130 transmits system information such as MIB and SIB to perform frequency synchronization and time synchronization with the terminal device 110 to prepare to process data transmitted from the 5G radio access network at any time. Can be.

As such, the control unit 113 receives information related to the use of the 5G radio access network transmitted from the eNB 120 through the communication unit 111 or information related to the use of the 5G radio access network transmitted from the gNB 130. Is received, the terminal device 110 recognizes that it is in a state capable of communicating through the 5G radio access network, and controls the display unit 112 to visualize and output information indicating that communication is possible through the 5G radio access network including the gNB 130. do.

Then, the display unit 112 outputs, as visualization information, information indicating that the terminal device 110 can communicate through the 5G radio access network under the control of the controller 113 (S240). For example, the display unit 112 outputs a " 5G " icon representing a 5G radio access network to a notification bar of a screen as illustrated in FIG. Regardless of whether the location is registered, the user of the terminal device 110 can accurately recognize the radio access network that can receive the service. For example, as illustrated in FIG. 4, the display unit 112 may simultaneously display reception sensitivity using a plurality of bar graphs. Alternatively, when the control unit 113 controls the display unit 112 to visualize and output information indicating that communication is possible through the 5G radio access network, the display unit 112 displays information indicating that communication is possible through the location-registered LTE radio access network. It can be controlled to output more as visualization information. For example, as illustrated in FIG. 5, the display unit 112 may simultaneously output an “LET” icon representing an LTE radio access network and a “5G” icon representing a 5G radio access network.

The controller 113 registers a location with the LTE wireless communication network when information related to the use of the 5G radio access network is not received from the eNB 120 or the NB 130 through the communication unit 111. In this state, the display unit 112 outputs information indicating that communication is possible through the LTE radio access network. Then, the display unit 112 outputs the "LTE" icon representing the LTE radio access network to the notification bar of the screen.

In addition, in step S230, the control unit 113 may distinguish and identify a state in which information related to the use of the 5G radio access network is received and communicate with the 5G radio access network and a state in which data is transmitted through the actual 5G radio access network. You can do that. To this end, the control unit 113 first controls the display unit 112 to output information indicating that the terminal device 110 can communicate through the 5G radio access network in step S240 in the first form. In this case, the display unit 112 may output a “5G” icon representing a 5G radio access network in a first form as illustrated on the left side of FIG. 6.

In addition, the control unit 113 controls the display unit 112 to output, as visualization information, information indicating that the data is being communicated through the 5G radio access network (S260) while actually transmitting data through the gNB 130 in the 5G radio access network. can do. To this end, the controller 113 controls the display unit 112 to output information indicating that the terminal device 110 is communicating through the 5G radio access network in a second form. In this case, as illustrated on the right side of FIG. 6, the display unit 112 may output a “5G” icon representing a 5G radio access network in a second form (S270).

As described so far, according to an embodiment of the present invention, in a mixed environment of a plurality of radio access networks, the terminal device outputs information indicating that the terminal device can communicate through a specific radio access network as visualization information. For example, even if the location registration to the EPC in the 5G NSA system is located in the region where the 5G service is available, the visualization information indicating the state that can receive the 5G service is output.

Therefore, the user can accurately recognize the radio access network that can receive the service regardless of which wireless communication network the terminal device has registered for the location.
