An electronic device according to various embodiments of the present invention may include an antenna module configured to sense an electromagnetic (EM) signal generated from an external electronic device, a communication module, a processor operatively connected to the antenna module and the communication module, and a memory storing instructions which, are configured to, when executed, cause the processor to identify the external electronic device based on at least part of the EM signal sensed from the external electronic device via the antenna module, identify whether the identified external electronic device is registered in a designated control application, and provide information related to the external electronic device based on whether the external electronic device is registered. In addition, other various embodiments of the present invention may be possible.

Techniques to recover from authentication failure are disclosed. During authentication of a user equipment (UE) with a public land mobile network (PLMN), the UE may receive an AUTHENTICATION REJECT with an extensible authentication protocol (EAP)-failure message. When this occurs, instead of invalidating the universal subscriber identity module (USIM) of the UE, the UE can search for other PLMNs that can potentially pass the authentication challenge. If one is found, the UE can register with the found PLMN.

The disclosure relates to a pre-5.sup.th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4.sup.th-Generation (4G) communication system such as Long Term Evolution (LTE). According to embodiments of the disclosure, a method performed by a Radio Access Network (RAN) Intelligent Controller (RIC) is provided. The method includes receiving a report message from an E2 node, generating a control message, based on the report message, and transmitting the control message to the E2 node. The control message may include an RAN configuration related to the E2 node. The report message may include at least one of User Equipment (UE) assistance information transmitted from a UE and UE expected behavior-related information transmitted from an Access and Mobility management Function (AMF).

A method and a device for setting a network mode of an electronic terminal are provided. The method includes monitoring whether a mobile communication network area where the electronic terminal is located has been changed, acquiring network status information of a current network area, in response to the mobile communication network area being changed, and setting the network mode based on the network status information of the current network area.

Examples pertaining to handling of multiple tracking area identifiers (TAIs) in satellite access in mobile communications are described. A user equipment (UE) initiates a procedure with a satellite-accessing cell of a network. The UE constructs a TAI or a plurality of TAIs, as a list of TAIs, of the cell depending on whether the broadcasts one or more than one tracking area codes (TACs) per public land mobile network (PLMN). The UE receives either a reject message or an accept message from the network responsive to initiating the procedure.

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method and apparatus for managing CAG related procedure in a wireless communication network is provided.

A wireless device sends a registration request message to an access and mobility management function (AMF) of a network. The wireless device receives, from the AMF, a registration accept message comprising an access traffic steering, switching, and splitting (ATSSS) capability indication of the network.
