Abstract: The invention relates to network nodes for handling non-fulfilment of QoS requirements in wireless communication systems. A first network node obtains QoS requirements associated with a PDU session of a client device application. When the QoS requirements will not be met in a core network, the first network node transmits a first QoS notification to a second network node, wherein the first QoS notification indicates that the one or more QoS requirements will not be met in the core network. When the QoS requirements will not be met in a radio access network, the first network node transmits a second QoS notification to a master node, wherein the second QoS notification indicates that the one or more QoS requirements will not be met in the radio access network. Furthermore, the invention also relates to corresponding methods and computer program.

Abstract: A first radio network node for assisting application adjustment is configured to receive a potential quality of service change notification (PQCN) from a second radio network; associate the PQCN with an in-advance quality of service prediction notification (IQN) recipient based on a mapping between a request for an IQN from an IQN recipient and an existing PQCN subscription, wherein the mapping is established based on a location, a required quality of service (QoS) and at least one of: configuration information associated with the IQN recipient or subscription information associated with the IQN recipient; and send an IQN to the IQN recipient for assisting the application adjustment.

Abstract: The invention relates to coordination of network function, NF, consumers subscribing to analytics events from a second network node. According to embodiments of the invention procedures for suppressing the notification related to an analytics event for specific NF consumers are introduced. The procedures are performed between a first network node and the second network node, where the first network node 100 may be seen as a controlling function and the second network node may be seen as a controlled function. The procedures are based on a list of NF consumers subscribing to an analytics event and their respective notification status associated with the analytics event. Depending on the list of NF consumers, the second network node may transmit or suppress notifications associated with the analytics event to the NF consumers.

Abstract: Configuration data associated with data traffic of at least one user equipment at a geographical area may be obtained at a home public land mobile network. The configuration data may comprise a mapping of the data traffic to an identifier of at least one co-located public land mobile network configured to provide access to an edge application server at the geographical area. The home public land mobile network may cause routing of the data traffic to the co-located public land mobile network based on the configuration data.

Abstract: A network node and method performed thereby, for enabling determination, by a prediction function network node, of a change in QoS of a communication session of a UE. The method includes obtaining information related to the UE communication session, the information including an ID of the UE and an ID of the communication session. The method further comprises determining the target serving cell of the UE and providing the obtained information and an ID of the determined target serving cell to the prediction function network node, thereby enabling the prediction function network node to determine new QoS of the UE communication session when being served by the target serving cell. A prediction function network node and a method performed thereby, and a user equipment and a method performed thereby are also disclosed.

Abstract: The disclosure relates to enhanced quality of service (QoS) monitoring. A first network entity receives a request for monitoring non-fulfilment of a QoS requirement of a packet data unit (PDU) session from a second network entity. Based on the received request, the first network entity obtains a QoS requirement of the PDU session from a third network entity and monitors for non-fulfilment of the obtained QoS requirement based on QoS estimates associated with the obtained QoS requirement. In response to detecting a non-fulfilment of the obtained QoS requirement, the first network entity transmits a second message to the second network entity, wherein the second message indicates the non-fulfilment of the obtained QoS requirement of the PDU session.

Abstract: Methods (300, 400) and nodes (150, 190) for assisting application adjustment are provided. A first radio network node (190) is configured to receive a PQCN from a second radio network (150); associate the PQCN with the IQN recipient (110) based on a mapping between a request for an IQN from an IQN recipient (110) and an existing PQCN subscription, wherein the mapping is established based on a location, a required QoS and at least one of: configuration information associated with the IQN recipient (110) or subscription information associated with the IQN recipient (110); and send an IQN to the IQN recipient (110) for assisting the application adjustment.
