A network operating system (NOS) acquires, for a plurality of network functions that achieve a network slice constructed on a mobile wireless communication network, information on an operation of each network function which is measured by one or more apparatus configured to provide at least a part of the plurality of network functions. The NOS derives an evaluation index value of each of the plurality of network functions based on the information on the operation of each of the plurality of network functions, and derives an evaluation index value of the network slice based on the evaluation index values of the plurality of network functions.

A negotiation method for an operating mode, an initiator, a receiver, a chip system, a computer-readable storage medium, and a functional entity are disclosed. In operating mode (OM) negotiation, the initiator transmits an operating mode indication (OMI) to the responder. The OMI includes at least either of channel width indication information and space-time stream number indication information. A capability range of a channel width indicated by the channel width indication information is greater than 160 MHz. A capability range of the number of space-time streams indicated by the space-time stream number indication information is greater than 8. After receiving the OMI, the responder performs transmission with the initiator based on a negotiated OM.

The disclosure relates to a communication technique and a system thereof that fuse a 5th generation (5G) communication system with Internet of Things (IoT) technology to support a higher data transmission rate after a 4th generation (4G) system. The disclosure is applied to intelligent services (e.g., smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security and safety-related service, etc.) based on 5G communication technology and IoT-related technology. The disclosure is about telecommunication and 5G network slicing technology. A method for defining a network slice template (NST) to provide network slice, for generating a network slice instance (NSI), and a system for managing them are provided.

Systems and methods are provided for public land mobile network (PLMN) selection for disaster roaming. A user equipment (UE) determines a disaster condition at a first PLMN, where the UE is a subscriber of the first PLMN. The UE determines an availability of a second PLMN for disaster roaming. The UE selects the second PLMN and attempts registration on the second PLMN for disaster roaming. In response to attempting the registration on the second PLMN for disaster roaming, the UE receives a registration reject message including a cause value corresponding to a registration failure for disaster roaming on the second PLMN due to the disaster condition on the first PLMN. The UE waits for a first period of time before again attempting to register for disaster roaming on the second PLMN for the first PLMN with the disaster condition.

The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system. A method performed by a user equipment (UE) in a wireless communication system is provided. The method includes selecting a stand-alone non-public network (SNPN) based on at least one of whether the SNPN supports a public warning system (PWS) or whether the SNPN supports an emergency call, transmitting, to a base station within the selected SNPN, a registration request message including information associated with supporting the PWS, and receiving, from the base station, a registration accept message.

A method of selecting, by a control entity, a network slice is provided. The method includes receiving a create session request message from a Serving Gateway (S-GW) in response to a Packet Data Network (PDN) connectivity request message transmitted by a terminal, transmitting, to a storage entity, a request message for subscriber information including identification information of the terminal, receiving, from the storage entity, subscription data of the terminal corresponding to the identification information of the terminal, selecting at least one network slice based on the subscription data of the terminal and slice information supportable by the control entity, and transmitting a create session response message including information of the selected at least one network slice, wherein the subscription data of the terminal includes information about a subscribed network slice of the terminal and information regarding whether the subscribed network slice of the terminal is supported in an Evolved Packet Core (EPC).

A method for fetching a content from a web server to a client device is disclosed, using tunnel devices serving as intermediate devices. The tunnel device is selected based on an attribute, such as IP Geolocation. A tunnel bank server stores a list of available tunnels that may be used, associated with values of various attribute types. The tunnel devices initiate communication with the tunnel bank server, and stays connected to it, for allowing a communication session initiated by the tunnel bank server. Upon receiving a request from a client to a content and for specific attribute types and values, a tunnel is selected by the tunnel bank server, and is used as a tunnel for retrieving the required content from the web server, using standard protocol such as SOCKS, WebSocket or HTTP Proxy. The client only communicates with a super proxy server that manages the content fetching scheme.
