A technique for communicating protocol data units, PDUs, in a radio communication from a transmitter (100) to a receiver (200) is described. As to a method aspect of the technique, one or more control messages indicative of Quality of Service, QoS, requirements for the radio communication are received. The QoS requirements include a control command for a reliability of the radio communication and a control command for a latency of the radio communication. A batch of redundant PDUs is transmitted from the transmitter (100) to the receiver (200). A number of the redundant PDUs per batch depends on the control command for the reliability and a temporal spread of the redundant PDUs per batch depends on the control command for the latency.

An electronic device and an operation method of an electronic device are provided. The electronic device includes a memory storing an application, an edge enabler client (EEC), and/or a user equipment (UE) route selection policy (URSP) rule used for producing a session used by the electronic device, a communication circuit used for a communication connection between the electronic device and at least one of a first server, a plurality of second servers, or a third server disposed outside the electronic device, via a base station, and a processor, the application being configured to perform, in the electronic device, one or more services corresponding to an application executable in the third server, and the processor is configured to identify identification information of the EEC and identification information of an EEC included in the URSP rule, in response to activation of the EEC, to set a first packet data unit (PDU) session.

In a wireless communication system of the present disclosure, when activation of a protocol data unit (PDU) session of a user equipment (UE) is needed, the UE performs an access control check to determine whether an access attempt for the PDU session is allowed. If the access attempt is allowed, the UE transmits a service request for the PDU session. The access control check for the PDU session is performed even if the UE is in a connected state.

The 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 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. The disclosure provides a method for supporting re-authentication of a PDU session generated through DN authentication/authorization with a DN-AAA server, and a method and an apparatus for managing a corresponding PDU session if DN authorization information is updated at the time of re-authentication.

Provided are a control method and device for a data packet duplication function, and a communication device. The control method for the data packet duplication function includes determining, by a communication device, to deactivate or activate a data packet duplication function; and performing, by the communication device, an operation of deactivating or activating the data packet duplication function correspondingly. Further provided is a storage medium.

In general, various aspects of the techniques described in this disclosure provide a sequence number checksum for link state protocols. In one example, the disclosure describes an apparatus, such as a network device, having a control unit operative to obtain link state information describing links between pairs of the network devices in a network topology, the link state information being fragmented into a plurality of link state protocol (LSP) fragments; compute a sequence number checksum from sequence numbers of the link state protocol (LSP) fragments; receive an LSP data unit from another network device in the network; determine whether a sequence number checksum in the LSP data unit matches a sequence number checksum computed from the link state information; and configure a delay for processing the LSP data unit in response to determining a mismatch between the sequence number checksum of the LSP data unit and the sequence number checksum computed from the link state information.
