Since the network configuration for the fourth type of service uses the 5G core network 150, functions such as network slicing or guaranteed bit rate (GBR) defined in the 5G standard can be utilized. The network configuration for the fourth type of service may be configured in the form of (C) or (D) depending on which logic the LTE base station 120 and the 5G base station 140 divide data into and transmit.

Referring to FIG. 1E , a network configuration for a fifth type of service in which an LTE base station 120 provides a medium-to-low delay and medium-reliability service using the 5G core network 150 is shown.

Referring to FIG. 1H, the 5G base station 140 transmits a control signal using the LTE core network 130, and the LTE base station 120 and the 5G base station 140 transmit data signals to the user terminal 110. A network configuration for an eighth type of service providing communication service is shown. The network configuration for the eighth type of service may be configured in the form of (g) or (h) depending on what logic the LTE base station 120 and the 5G base station 140 divide data into and transmit.

2 is a diagram for explaining a cell structure of a network according to an exemplary embodiment. Referring to FIG. 2, serving cells 201 of a user terminal 210, an LTE base station 220, an LTE core network (EPC) 230 corresponding to the LTE base station 220, and serving cells of a 5G base station 240 203 is shown.

The user terminal 210 may receive a communication service from the LTE base station 220 or the 5G base station 240 according to its location in the network. For example, as shown in FIG. 2, when the user terminal 210 is located in the serving cells 201 of the LTE base station 220, the LTE base station 220 uses the LTE core network 230 to provide the user terminal A control signal may be transmitted to (210). At this time, in addition to the LTE base station 220, the 5G base station 240 may also provide a high-speed communication service to the user terminal 210 by transmitting a data signal to the user terminal 210. The network structure shown in FIG. 2 corresponds to the network configuration for the above-described third type of service, and the LTE base station 220 mainly uses the LTE nationwide network and additionally connects the 5G base station 240 to download data and/or increase the speed of the upload. Through this, it is possible to provide ultra-high-speed service, one of the attributes of 5G service, while maintaining the LTE core network 230 without the 5G core network.

3 is a flowchart illustrating a method of operating a user terminal according to an exemplary embodiment. Referring to FIG. 3, a user terminal according to an embodiment receives a system information message broadcast from a serving base station (310). A 'serving base station' may be understood as a base station from which a user terminal is currently receiving a service within a serving cell of a network. For example, when a user terminal is provided with a communication service by an LTE base station in a serving cell of an LTE network, the serving base station of the user terminal may be an LTE base station. Alternatively, when a user terminal is provided with a communication service by a 5G base station in a serving cell of a 5G network, the serving base station of the user terminal may be a 5G base station. Here, the system information message includes information bits indicating at least one of 5G service availability and any one service type available to the user terminal among preset 5G service types based on the location of the user terminal.

The system information message may be, for example, a System Information Block Type 2 (hereinafter 'SIB 2') message. The SIB 2 message may include radio resource configuration information common to all user terminals. Radio resource configuration information includes, for example, access class barring configuration, RACH related configuration, timer, UL power control, and sounding reference signal configuration. configuration), etc. The SIB 2 message may be transmitted from the network to the user terminal through, for example, BCCH → DL-SCH → PDSCH channel. The user terminal may receive the SIB 2 message not only in a state connected to the LTE base station (eNB) (RRC connected), but also in a standby state not connected to the LTE base station (RRC idle). Here, the 'standby state' may be understood as a state in which the user terminal is not connected to the LTE base station but is managed by a higher Mobility Management Entity (MME). Also, the information bit may be, for example, an upperLayerIndication bit. The upperLayerIndication bit may correspond to a bit indicating that the 5G cell is in the same location to upper layers of the protocol stack.

The user terminal extracts and decodes information bits from the system information message (320). The information bit may be, for example, a single bit of 1 bit or multiple bits of 3 bits. The information bit may indicate at least one of whether the location corresponds to a 5G service available area and any one service type available to the user terminal at the location among preset 5G service types based on the location of the user terminal in the network. . The information bit can be used to inform the user terminal of various 5G network environments. The user terminal can determine available 5G services by information bits.

The user terminal controls the operation of the user terminal according to any one service type based on the information bits decoded in step 320 (330). For example, the user terminal may compare the information bits decoded in step 320 with a preset mapping table. In this case, an example of a preset mapping table may refer to FIG. 7 below. The user terminal may determine one service type available to the user terminal based on the comparison result. The user terminal may control the operation of the user terminal according to any one service type.

Alternatively, the user terminal may display an icon corresponding to any one service type based on the information bits decoded in step 320. The user terminal may compare the decoded information bits with a preset mapping table. Based on the comparison result, the user terminal may determine an icon corresponding to any one service type available to the user terminal. The user terminal may display the determined icon on the display screen.

For example, when the decoded information bit is '1', the user terminal displays an icon indicating whether 5G service is available on the display screen, and when the decoded information bit is '0', the user terminal indicates that 5G service is unavailable. The indicated icon may be displayed on the display screen.

Or, for example, as a result of comparing the decoded information bit ('011') with the mapping table shown in FIG. 7, it is assumed that the user terminal can use the fourth type of 5G service. In this case, the user terminal may display a 5G icon C corresponding to the fourth type of 5G service on the display screen.

The user terminal may transmit information about whether 5G service is available and any one service type to at least one application using the 5G service installed in the user terminal.

In addition, the user terminal can control the operation of the user terminal by updating the service type according to the updated system information message. The user terminal may receive an updated system information message from the serving base station and update any one service type based on information bits included in the updated system information message. The user terminal may control the operation of the user terminal according to the updated service type.

4 is a diagram for explaining a process of notifying a user terminal of a 5G service area according to an embodiment. Referring to FIG. 4 , a 5G (NR gNB) base station 401 , an LTE (eNB) base station 403 and a 5G supporting terminal 405 are shown.

When the 5G base station 401 and the LTE base station 403 maintain a connection state with the aforementioned third type of 5G network structure, the LTE base station 403 transmits system information to the 5G supporting terminal 405 using the LTE core network. A message (eg, a SIB 2 message) may be broadcast (410).

The 5G support terminal 405 may determine whether the value of the information bit (eg, upperLayerIndication) is '1' or '0' among various contents in the SIB 2 message (420).

If it is determined that the information bit is '1', the 5G supporting terminal 405 may display a 5G icon on the screen of the terminal (430). In contrast, when it is determined that the information bit is '0', the 5G supporting terminal 405 may display an LTE icon on the screen of the terminal (440).

5 is a diagram for explaining operations of a base station and a terminal based on a third type of 5G network configuration according to an embodiment. Referring to FIG. 5 , a 5G (NR Gnb) base station 501 , an LTE (eNB) base station 503 and a 5G supporting terminal 505 are shown.

When the 5G base station 501 and the LTE base station 503 maintain a connection state with the above-described third type of 5G network structure, the LTE base station 503 uses the LTE core network 505 to support the 5G terminal 507 A SIB 2 message may be broadcast to (510). At this time, suppose that the value of the information bit included in the SIB 2 message is "010".

Upon receiving the SIB 2 message, the 5G supporting terminal 507 can demodulate the SIB 2 message and confirm that the value of the information bit is "010" (520). The 5G supporting terminal 507 may display a 5G icon B corresponding to the third type of 5G service on the terminal screen (530).

In addition, the 5G supporting terminal 507 may transmit the fact that the corresponding service is “available” to an app using a fifth type of 5G service (eg, 5G high-speed service) inside the terminal (540). At this time, the 5G supporting terminal 507 may transmit information about whether 5G service is available and the service type (ie, the third type) that provides 5G high-speed service to the app, or may transmit only information about the service type. .

The 5G support terminal 507 may determine whether to update the service type based on whether there is a changed bit in the value of the information bit included in the next transmitted SIB 2 message, that is, whether or not there is a change content (550).

For example, when the value of the information bit included in the next transmitted SIB 2 message is changed, the 5G support terminal 507 may be controlled according to the service type based on the changed value. Alternatively, if the value of the information bit included in the next transmitted SIB 2 message is not changed, the 5G supporting terminal 507 may be controlled according to the same service type as before.

6 is a diagram for explaining operations of a base station and a terminal based on a fifth type of 5G network configuration according to an embodiment. Referring to FIG. 6, an LTE (eNB) base station 601, a 5G core network 603, and a 5G supporting terminal 605 are shown.

When the LTE base station 601 uses the 5G core network 603 to connect to the 5th type of 5G network structure that provides medium-low delay and medium-reliability services, the LTE base station 601 uses the 5G core network 603 Thus, the SIB 2 message may be broadcast to the 5G supporting terminal 605 (610). At this time, suppose that the value of the information bit included in the SIB 2 message is "100".

Upon receiving the SIB 2 message, the 5G supporting terminal 605 can demodulate the SIB 2 message and confirm that the value of the information bit is “100” (620). The 5G supporting terminal 605 may display a 5G icon D corresponding to the fifth type of 5G service on the terminal screen (630).

In addition, the 5G-supporting terminal 605 may transmit the fact that the corresponding service is “available” to an app using a fifth type of 5G service (eg, medium-low delay and medium-reliability 5G service) inside the terminal ( 640). At this time, the 5G supporting terminal 605 may transmit information about whether 5G service is available and the service type (ie, fifth type) that provides 5G high-speed service to the corresponding app, or may transmit only information about the service type. .

The 5G supporting terminal 605 may determine whether to update the service type based on whether there is a changed bit in the information bits included in the next transmitted SIB 2 message, that is, whether or not the service type is updated (650).

For example, when the value of the information bit included in the next transmitted SIB 2 message is changed, the 5G supporting terminal 605 may be controlled according to the service type based on the changed value. Alternatively, if the value of the information bit included in the next transmitted SIB 2 message is not changed, the 5G supporting terminal 605 may be controlled according to the same service type as before.

7 is a diagram illustrating an example of a mapping table according to an embodiment. A user terminal and a base station according to an embodiment may each equally include a mapping table. In this case, the mapping table may map 5G network configuration options and 5G icons for each bit configuration of information bits (eg, 3 bits) included in the SIB 2 message.

Referring to FIG. 7, it can be seen that when the base station is a 5G base station, the E2E delay is reduced, and when the core network is a 5G core network, the bit rate (speed and delay) is guaranteed. From this point of view, the type of 5G service that the user can experience may vary depending on what kind of 5G network configuration is possible where the user terminal is currently located.

Accordingly, the base station may inform the user terminal of the 5G service type that can be provided based on the location of the user terminal in the network through information bits included in the system information message. In addition, the user terminal can check these contents through information bits and use them usefully to determine whether an app or service installed inside the user terminal can be used. In addition, the user terminal can recognize the contents to the user by displaying the currently available service types identified through the information bits as 5G icons of various types or shapes.

8 is a flowchart illustrating a method of operating a base station according to an embodiment. Referring to FIG. 8, a base station according to an embodiment determines one of 5G service types that can be provided to a user terminal according to preset 5G network configuration options based on a location of the user terminal in the network.
