An application, executed by a User Equipment (“UE”), may receive an identifier, which may be used to monitor Key Performance Indicators (“KPIs”) associated with the UE. Such KPIs may be monitored in conjunction with execution of the application, such as at times that the application sends and/or receives traffic. The KPIs may be associated with sensor data, resources, and/or other features or functionality of the UE. The UE may obtain an identifier associated with the application and/or the UE from a KPI monitoring system of some embodiments, may obtain user consent to monitor and/or report KPIs associated with the application, and may provide such KPIs to the KPI monitoring system in conjunction with the identifier. The KPI monitoring system may generate aggregated KPI information, associated with the application, based on the KPIs received from the UE and/or KPIs received from one or more other sources.

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.

Certain aspects of the present disclosure provide techniques for implementing reflective quality of service (RQoS) in wireless communication systems. A method for implementing RQoS that may be performed by a user equipment (UE) generally includes receiving a plurality of downlink user data packets from a first base station (BS), determining at least one reflective quality of service (RQoS) mapping rule for one or more uplink packet transmissions based on a subset of the plurality of downlink user data packets, filtering the plurality of downlink user data packets based on the at least one RQoS mapping rule, and forwarding the plurality of downlink user data packets to a corresponding application entity of the UE based on the filtering.

In the field of payment terminals, a new generation of modular, function-rich payment terminals is appearing. Such smart payment terminals transmit, equally well, data relative to payment transactions and, for example, data relative to software updates. However, at present, a smart payment terminal in incapable of transmitting different data in accordance with their respective transmission constraints. This can represent a considerable cost for the merchant. A communications device is therefore provided to set up two connections simultaneously with two different gateways and thus be capable of exchanging data associated with different transmission parameters. Thus, the communications device can simultaneously transmit data relative to different types of services having distinct transmission parameters.

This application provides example methods, systems, and devices for performing charging on a network resource. One example method includes sending, by a network slice charging function device, a first message to a network slice management function device, where the first message includes an identifier of a network slice instance and filtering information, the filtering information indicates the network slice management function device to send a value that is of a network slice performance indicator of the network slice instance and that matches the filtering information, and the network slice performance indicator describes network performance of the network slice instance. The network slice charging function device can then receive a second message from the network slice management function device, where the second message includes the value. The network slice charging function device can then perform charging on the network slice instance based on the value.

On-demand quality of service guarantees are provided in a wireless network environment. The system determines an on-demand quality of service for a segment of a communication path between a user equipment communicating with a radio access network connected to a core network and an external network connected to the core network. The system then determines if the on-demand quality of service for the segment meets a quality of service requirement. If the on-demand quality of service for the segment does not meet the quality of service requirement, the system identifies an alternate communication path between the user equipment and the external network, wherein the alternate communication path differs from the communication path. The system can then setup the alternate communication path for traffic between the user equipment and the external network.

In a communication system having a plurality of user equipment (UE) devices that are operating in a contention based mode for device-to-device (D2D) communication, each UE device transmits a preferred transmission indicator when a condition for preferred transmission is met at the UE device. If a UE device receives a preferred transmission indicator, the UE device delays transmission of a D2D scheduling assignment (SA) to contend for communication resources for D2D communication. The length of the delay can be based on a number of preferred transmission indicators that are received. The preferred transmission indicator is based on a buffer size in one example.

A radio access network handover method of a base station in a 5G radio access network (5G-RAN) is are disclosed. The method comprising: determining handing over a user equipment (UE) to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN); transmitting a handover requirement message to an Access and Mobility Management Function (AMF); receiving a handover command message from the AMF and transmitting the handover command message to the UE, the handover message such that the UE is handed over from the 5G-RAN to the E-UTRAN; and performing indirect data forwarding to a base station in the E-UTRAN.

A technique of transporting a time protocol message for time-sensitive networking, TSN, from a first station (910) to a second station (920) through a wireless network (900) including at least one radio device wirelessly connected to at least one base station (400) of the wireless network (900) is provided. As to a method aspect, a method performed by at least one or each of the at least one radio device comprises a step of transmitting to the wireless network (900) a radio device request message requesting establishment of a packet data unit, PDU, session between the radio device and the wireless network (900), the radio device request message being indicative of a time protocol of the time protocol message. The method further comprises at least one of the steps of receiving from and transmitting to the at least one base station (400) of the wireless network (900) the time protocol message according to a Quality of Service, QoS, flow for transporting the time protocol message in the wireless network (900). The QoS flow is unambiguously or uniquely associated with at least one of the PDU session and the time protocol.

The present disclosure relates to a communication method and system for converging a 5.sup.th-Generation (5G) communication system for supporting higher data rates beyond a 4.sup.th-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 processing a packet by a transmission device in a wireless communication system according to an embodiment of the present invention comprises the steps of: checking whether a data radio bearer (DRB) mapped to a quality of service (QoS) flow changes from a first DRB to a second DRB; and when the DRB changes from the first DRB to the second DRB, transmitting, to a reception device, information on a last packet transmitted through the first DRB in the QoS flow.
