Wireless communication methods are described for a user plane integrity protection failure detection and handling, determination and management of integrity protection enabled data rate that exceeds or is close to exceeding a user equipment's capability or threshold, and management of integrity protection or encryption mechanisms in a dual-connectivity system that includes a master network node and a secondary network node.

Disclosed in the present invention are an integrity protection control method, a network device and computer storage medium, the method comprising: acquiring parameter configuration information, wherein the parameter configuration information is parameter configuration information saved by a network device or parameter configuration information acquired from a core network side; and on the basis of the parameter configuration information, determining whether it is necessary to start integrity protection for a quality of service (QoS) data flow.

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 for replacement of a DNN and/or S-NSSAI in a wireless communication system is provided.

A network architecture and methods of managing packet data unit (PDU) sessions in a network are provided. The methods include PDU session establishment procedures, PDU session modification procedures, PDU session state transfer procedures, PDU session release procedures, and user equipment (UE) handover procedures.

The present invention provides methods, apparatuses and systems supporting in-order packet delivery during application relocation or UP (User Plane) path management events such as DNAI (Data Network Access Identifier) changes. In-order packet delivery may be enforced, ensured or supported by using an indication that in-order packet delivery is requested or required for a particular traffic flow of a UE during a user plane path management event. The methods may be performed by apparatuses implementing an application function (AF), a policy control function (PCF), a session management function (SMF), or UP entities such as PDU session anchors, of the communication network, or systems implementing a combination thereof. The SMF may configure UP entities to transmit packets and flow end markers to support in-order packet delivery and provide flow end marker information to the UP entities. The UP entities may signal path changes using flow end markers.
