[0003] With the recent commercialization of 5G networks and the significant improvements in mobile network speed and capacity, the importance of edge computing and artificial intelligence technologies is increasing. These technological advancements have enabled more complex and data-intensive services in mobile environments, and users are increasingly demanding information about which networks their devices are currently connected to and what features they support.

[0004] However, most current mobile devices simply display the network type (e.g., 3G, 4G, 5G), making it difficult for users to easily recognize the network's capabilities (e.g., whether edge AI is supported).

[0018] The advantages and features of the present invention, and the methods for achieving them, will become clearer with reference to the embodiments described below together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below and may be implemented in various different forms. These embodiments are provided solely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined solely by the scope of the claims.

[0019] When describing embodiments of the present invention, detailed descriptions of known functions or configurations will be omitted if they are deemed to unnecessarily obscure the gist of the invention. Furthermore, the terms described below are defined in light of their functions in the embodiments of the present invention and may vary depending on the intent or custom of the user or operator. Therefore, their definitions should be based on the overall content of this specification.

[0020] The present disclosure relates to a device and method for displaying connected network information. Specifically, the present disclosure describes a technique for displaying connected network information in a wireless communication system.

[0021] The terms used in the following description, including terms referring to signals, channels, control information, network entities, and device components, are provided for convenience of explanation. Therefore, the present disclosure is not limited to the terms described below, and other terms with equivalent technical meanings may be used.

[0022] Additionally, while this disclosure describes various embodiments using terminology used in certain communication standards (e.g., 3rd Generation Partnership Project (3GPP)), these are merely illustrative examples. The various embodiments of this disclosure can be easily modified and applied to other communication systems.

[0023] A base station may be a network infrastructure that provides wireless access to terminals. A base station may have coverage defined as a certain geographic area based on the distance at which a signal can be transmitted. In addition to a base station, a base station may be referred to as an "access point (AP)", an "eNodeB (eNB)", a "5th generation node", a "wireless point", a "transmission / reception point (TRP)", a "next generation Node B (gNodeB, gNB)", or other terms having equivalent technical meanings.

[0024] Each terminal is a device used by a user and can communicate with a base station via a wireless channel. In some cases, at least one of the terminals can be operated without the user's intervention. That is, at least one of the terminals is a device that performs machine type communication (MTC) and may not be carried by the user. Each of the terminals may be referred to as a 'user equipment (UE)', a 'mobile station', a 'subscriber station', a 'remote terminal', a 'wireless terminal', a 'user device', or other terms having equivalent technical meanings.

[0025] A network refers to the entire system for providing wireless communication services, and may include both a radio access network (RAN) and a core network (CN). The support for edge AI infrastructure in this disclosure indicates the capabilities of the entire network system and can be provided through collaboration between the RAN and CN.

[0026] FIG. 1 illustrates an operation method of a terminal that displays a network connected to the terminal according to one embodiment of the present disclosure.

[0027] Referring to FIG. 1, the terminal can receive a network display setting signal in use to display the network connected to the terminal (101).

[0028] The terminal can receive an AI infrastructure indicator (103) within a system information block (SIB) transmitted from the network, indicating whether the network is a network with edge AI infrastructure. For example, the AI ​​infrastructure indicator can be expressed as Ai_Infra, and depending on whether Ai_Infra is true or false (e.g., Ai_Infra=true or false), whether the network is a network with edge AI infrastructure can be determined.

[0029] The terminal can generate network information based on the received network indication setting signal and the received AI infrastructure indicator (105).

[0030] If the network supports edge AI infrastructure, the terminal can display a service mark indicating edge AI infrastructure on the terminal based on network information (107).

[0031] For example, according to one embodiment, if the network transmits basic information about the network (e.g., MasterInformationBlock and systemInformationBlockType1) to display a service mark indicating network information on the terminal, and the basic information about the network corresponds to a 4G network, and the network supports edge AI infrastructure and transmits an AI infrastructure indicator (e.g., Ai_Infra or Ai_Infra = true) through a system information block, the terminal may display 'LTE-AI' on the terminal.

[0032] In another embodiment, the terminal may display '5G-AI' on the terminal when the network transmits basic information about the network (e.g., MasterInformationBlock and systemInformationBlockType1), the basic information about the network (e.g., systemInformationBlockType2) corresponds to a 4G network, and the system information block has an indicator that supports NSA 5G (non-standalone 5G) (e.g., upperLayerIndication-r15 = true), or when the network transmits basic information about the network (e.g., MasterInformationBlock and systemInformationBlockType1), the basic information about the network corresponds to a SA 5G (standalone 5G) network, and the network supports edge AI infrastructure and transmits an AI infrastructure indicator (e.g., Ai_Infra or Ai_Infra = true) through the system information block.

[0033] In one embodiment, basic information about the network may include a master information block (MIB) or a system information block (SIB).

[0034] Additionally, if the terminal does not support AI infrastructure, a service mark indicating edge AI infrastructure may be displayed on the terminal based on network information corresponding to the network. For example, according to one embodiment, if the network is 4G and does not support edge AI infrastructure, the terminal may display "LTE." If the network does not support edge AI infrastructure, the terminal may display "5G."

[0035] Additionally, the terminal may transmit information to the network regarding whether AI operations are possible (e.g., presence or absence of 'AIcapability' or AIcapability = true / false) in terminal capability information (e.g., UECapabilityInformation).

[0036] Additionally, the terminal may transmit information to the network about the quality level required for the AI ​​service (e.g., RequiredAIQoS) in a measurement report (e.g., MeasurementReport).

[0037] This is specifically illustrated in Fig. 3.

[0038] FIG. 2 illustrates an example of a service mark notation for AI service activation according to one embodiment of the present disclosure.

[0039] Referring to FIG. 2, a service mark (203) is displayed on a terminal (200) depending on whether the connected network is 4G or 5G. For example, in the case of 4G, it may be displayed as LTE, and in the case of 5G, it may be displayed as 5G. Currently, in Korea, a 4G network is built nationwide, and if 5G is built together with a 4G network in a system where 5G is built on top of a 4G network (e.g., NSA 5G, Non-standalone 5G), the network may send a signal of 'Upper layer indication = true' to the terminal (200), and if 5G is not built, it may send a signal of 'Upper layer indication = false'.

[0040] When the terminal (200) (e.g., 5G smartphone) receives 'Upper layer indication = true', it can display a 5G service mark, and when it receives 'Upper layer indication = false', it can display a 4G service mark.

[0041] According to one embodiment, information about 'Upper layer indication = true or false' may be transmitted in a system information block (SIB) (e.g., systemInformationBlockType2).

[0042] As AI services become more active, Edge AI infrastructure, a service-based AI infrastructure that accelerates artificial intelligence and machine learning inference, may be actively built to support AI services. Accordingly, if a network with Edge AI infrastructure exists (e.g., Ai_infra = true), an additional service mark (203) may be required to notify users of the presence of a network with Edge AI infrastructure.

[0043] According to one embodiment, a network with Edge AI infrastructure may be a network in which a terminal-adjacent data center is built to provide AI services.

[0044] The terminal (200) can receive a network display setting signal for displaying a network in use. Here, the network display setting signal is preferably a signal that sets the environment of the terminal (200) for displaying a network, but is not necessarily limited thereto, and may also include a network display mode in use that displays a network currently connected and in use.

[0045] If the network of the area receiving the service supports edge AI infrastructure (e.g., Ai_infra = true), the network informs the terminal (200) of whether or not the edge AI infrastructure is supported, and the terminal (200) displays a service mark (203) indicating the AI ​​service on the screen so that the user can recognize whether or not the AI ​​infrastructure is supported.

[0046] The terminal (200) can generate network information based on whether the network has an edge AI infrastructure built on it.

[0047] In one embodiment, the network may use an identifier (e.g., AI Infra) to indicate whether the network supports edge AI infrastructure when a terminal connects to the network or performs a handover to move the network. For example, if an identifier (e.g., AI Infra) is added as network information, and 'AI infra=false' is set, the terminal can identify that the network does not support edge AI infrastructure, and if 'AI infra=true' is set, the terminal can identify that the network supports edge AI infrastructure.

[0048] In one embodiment, if the network to which the terminal is connected does not support edge AI infrastructure (e.g., 'AI infra=true'), the terminal may indicate that edge AI infrastructure is configured in the network along with a mark indicating the network to which the terminal is connected. For example, if the terminal is connected to a 4G network (e.g., 'Upper layer indication = false' and 'AI infra=true'), the terminal may display 'LTE-AI' as the service mark, and if the terminal is connected to a 5G network (e.g., 'Upper layer indication = true' and 'Ai infra = true'), the terminal may display '5G-AI' as the service mark.

[0049] In another embodiment, if the network connected to the terminal does not support edge AI infrastructure (e.g., 'AI infra=false'), the terminal may display 'LTE' as the service mark when connected to a 4G network, and may display '5G' as the service mark when connected to a 5G network.

[0050] FIG. 3 illustrates a signal flow diagram between a terminal and a network for exchanging capability information according to one embodiment of the present disclosure.

[0051] Referring to FIG. 3, the terminal can transmit an RRC (radio resource control) connection request message to the network (301).

[0052] The network may send a UE Capability Enquiry message to request UE (user equipment) capability information from the terminal (303). In one embodiment, the UE Capability Enquiry message may include the type of capability the network is interested in knowing.

[0053] For example, a UE Enquiry message may include a request for information about whether the terminal is capable of AI calculation (e.g., AI calculation available).

[0054] As another example, a UE Enquiry message may include a request from the network for the quality level required for the AI ​​service the terminal wishes to use.

[0055] The terminal can transmit a UE Capability Information message to the network in response to the UE Capability Enquiry message (305).

[0056] In one embodiment, the UE Capability Information message may include information regarding whether the terminal is capable of AI calculations (e.g., "AI calculation available"). Being capable of AI calculations means that the terminal is capable of a certain level of AI calculations or inferences on its own. This may imply that some AI calculations can be performed on the terminal rather than all in a data center or edge AI infrastructure, thereby enabling faster provision of AI services.

[0057] For example, if a terminal sends information to the network about whether AI calculation is possible (e.g., AI calculation available) or sends 'AI calculation available = false', it can be identified as a terminal that cannot perform AI calculation. If the terminal sends information about whether AI calculation is possible (e.g., AI calculation available) or sends 'AI calculation available = true', it can be identified as a terminal that can perform AI calculation.

[0058] The network can transmit its capability information to the terminal via an RRC Reconfiguration message (307).

[0059] In one embodiment, the RRC Reconfiguration message may include information about whether the terminal is capable of AI calculation (e.g., AI calculation available).

[0060] In another embodiment, the RRC Reconfiguration message may include information about the quality level required for the AI ​​service the terminal wishes to use from the network. This allows the network to detect the AI ​​service and independently determine the required quality level.

[0061] According to one embodiment, 4G may use QCI (QoS Class Identifier) ​​and 5G may use 5QI (5G QoS identifier) ​​as indicators of quality level (quality level, QoS) transmitted between a terminal and a network. Specifically, when a terminal uses an AI service, it may request a desired QoS for the AI ​​service from the network. For example, by utilizing the 4G QCI or 5G QI table, the terminal may inform the network of the QoS table number it wishes to be guaranteed when receiving an AI service (e.g., 1, 2, 3, 4, 5... of 4G QCI or 1, 2, 3, 4, 5... of 5G QI).

[0062] Additionally, for example, it can indicate the quality level in steps defined between the terminal and the network (e.g. Service level 1: delay 500ms, PER 10). -4 Within, Service level 2: Delay 200ms, PER 10 -4 Within, Service level 3: Delay 50ms, PER 10 -6 Within, Service level 4: Delay 10ms, PER 10 -8 within)

[0063] The terminal can send an RRC Reconfiguration Complete message to the network. By sending the RRC Reconfiguration Complete message, the terminal can complete the exchange of capability information between the network and the terminal (309).
