Abstract: The disclosure relates to the 5th generation (5G) or 6th generation (6G) communication system to support a high data transmission rate than before. A method of operating a streaming service client (SSC) node in a wireless communication system is provided. The method includes an operation of establishing a connection to a streaming service provider (SSP) via two types of services that are enhanced mobile broadband (eMBB) and ultra reliable low latency communication (URLLC), an operation of receiving first data from the SSP via the eMBB, and simultaneously receiving second data via the URLLC, wherein the second data is metadata of the first data, and operation of determining whether the first data is successfully received, and an operation of producing a data stream using the second data in a case in which the first data is not successfully received.

Abstract: 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.

Abstract: An apparatus and a method for generating a descriptor for a network slice are provided. The apparatus includes a transceiver, a memory storing one or more instructions, and at least one processor configured to execute the one or more instructions stored in the memory to obtain requirements for a network slice, determine at least one of a plurality of network slice templates (NSTs), a plurality of network slice descriptors (NSLDs), or a plurality of network slice instances (NSIs), based on the obtained requirements, when at least one of the plurality of NSTs is determined, determine at least one specific node to substitute for a plurality of abstract nodes included in the at least one of the plurality of NSTs, based on the obtained requirements, and generate a descriptor for a network slice, based on the determined at least one specific node.

Abstract: Various embodiments of the disclosure provide a device performing communication and a method for operating the same. According to an embodiment, an operation method comprise receiving, by the AMF, a registration request message from a user equipment (UE) through a base station, the registration request message including network slice selection assistance information (NSSAI) requested from the UE, identifying, by the AMF, whether the requested NSSAI can be serviced, transmitting, by the AMF, a message for requesting a target AMF capable of servicing the requested NSSAI to a network slice manager (NSM) through a network slicing selection function (NSSF) when the requested NSSAI cannot be serviced, and receiving, by the AMF, information regarding the target AMF from the NSM through the NSSF and transmitting the information regarding the target AMF and NSSAI allowed by the target AMF to the base station.

Abstract: In a cellular communications network including user equipment and an access network, a cell-blocking method involves designating a cell in the network that is to be blocked and activating a cell-blocking operating mode of a node of the access network of the cellular communications network. According to the cell-blocking method, upon activation of the cell-blocking mode of the access-network node, active calls in the designated cell are detected and disconnected. The disconnection of active calls may be performed selectively based on an access class or establishment cause associated with the call. The cell-blocking may be hidden because the access-network node may not broadcast any data that is indicative of cell-blocking and, when a user equipment in the affected cell attempts to set-up a call, the access-network node may reject the call using an admission control mechanism or may send back a spoofed message from the core network.
