There are provided measures for optimization of network function profile administration and registration. Such measures exemplarily comprise, at a network repository function entity, receiving, from a control entity, network entity profile template information, storing said network entity profile template information, wherein said network entity profile template information comprises a network entity profile template including an identifier of said network entity profile template and a profile content of said network entity profile template, said profile content including at least one profile attribute, receiving, from a network entity, a network entity registration request comprising said identifier of said network entity profile template, and generating a network entity profile for said network entity based on said at least one profile attribute.

Optimization of network function profile administration and registration

There is provided an apparatus configured to receive, from a first network entity associated with a first domain in a communication network, a request to communicate; determine a second network entity to which to send the request; determine that the second network entity is associated with a second domain in the communication network; and enforce at least one access policy for routing the request to the network entity, wherein the apparatus is a first service communication proxy trusted in both the first and second domains.

Apparatus, methods, and computer programs

Methods and apparatus, including computer program products, are provided for handovers including fallbacks. In some example embodiments, there is provided an apparatus comprising at least one processor and at least one memory including program code which when executed causes the apparatus to at least: receive, during creation or modification of a bearer, a message including a handover threshold based at least in part on a type of codec for the bearer; receive, from a user equipment, a measurement report providing an indication of a condition of the bearer and/or perform a measurement, by the base station, providing the indication of the condition of the bearer; determine, based at least on the handover threshold, whether to initiate a handover. Related apparatus, systems, methods, and articles are also described.

Providing handover thresholds to the RAN

A method, apparatus, and computer program product relating to notification requests and callback requests in indirect communications are provided. In the context of a method, the method includes sending a service request for selection of a service consumer. The service request is one of a notification request or a callback request. The method further includes indicating a version of a programming interface configured to support the service request.

Notifications sent with indirect communication in SBA

Systems, methods, apparatuses, and computer program products for event subscription notification(s) are provided. One method may include providing, from a first network entity, a policy control request trigger about subscriptions for event exposure to a second network entity. The method may also include receiving a notification, from the second network entity, about the policy control request trigger, and installing or updating at least one policy and charging control (PCC) rule based on the information received in the notification from the second network entity.

Event subscription notification

Systems, methods, apparatuses, and computer program products for discovering a network function (NF) acting as a network function service consumer are provided. One method may include, when a NF service consumer subscribes to notifications from a NF service producer, receiving, by the NF service producer, subscription information including a name of a consumer service of the NF service consumer that subscribes to notifications of the NF service producer. The receiving of the subscription information with the name of the consumer service allows the NF service producer to discover a corresponding NF service from an alternative NF instance within a NF set.

Methods and apparatuses for discovering a network function acting as network function service consumer

Systems, methods, apparatuses, and computer program products for UPF control with coexistence of policy control and packet filters dynamically generated at the SMF. For example, if the SMF obtains an event subscription with traffic descriptors from another entity, and if there is no installed PDR with the same traffic descriptor, the SMF may construct a PDR with an action according to the subscribed event. The SMF may configure the UPF with the constructed PDR. In certain embodiments, to construct the PDR, the SMF may copy the PDR that would have previously matched the incoming traffic described by the traffic descriptor in the notification subscription, and associates the PDR with a higher priority, the traffic descriptor and a notification action according to the subscribed event. To configure the UPF, the SMF may provide the PDR with the higher priority, the received traffic descriptor, and the notification action, according to some embodiments.

User plane function (UPF) control with coexistence of policy control and packet filters dynamically generated at the session management function (SMF)

There are disclosed measures of network entity selection, for example including furnishing an identity of a network entity being pre-selected by a first network apparatus, and providing verification information for said pre-selected network entity identity, enabling to verify whether the pre-selected network entity identity is applicable for network entity selection at a second network apparatus.

Network entity selection

Methods and apparatus, including computer program products, are provided for transport method selection of asynchronous notifications. In some example embodiments, there may be provided a method that includes sending, by a client, a hypertext transfer protocol request for at least one asynchronous notification to be sent by a server to the client, the hypertext transfer protocol request including at least one proposed transport method for carrying the at least one asynchronous notification; determining, by the client, whether a first transport method selected by the server from the at least one proposed transport method is successfully established; and when the determination is that the first transport method is not established successfully, sending, by the client, another hypertext transfer protocol request to the server, the other hypertext transfer protocol request including at least one other proposed transport method. Related systems, methods, and articles of manufacture are also described.
