Abstract: A method performed in a CP node. The method comprises setting a TQM in a URR to which its corresponding SDFs are applicable for envelope reporting, setting at least one reporting trigger in the URR, to instruct the UP function to generate a usage report upon closure of an envelope, setting a measurement method in the URR, to instruct the UP function to collect usage of volume, time and/or event, sending the set URR to the UP function, receiving one or more usage reports from the UP function, in response to the sent URR, wherein the received usage report(s) comprises at least a usage report trigger set to envelope closure, determining a starting time and/or an ending time for each envelope, based on the received usage report(s), and storing each envelope, with the determined starting time and/or ending time, for online or offline charging.

Abstract: An enhanced communication of recovery information related to restart of a NF Service provider of NF consumer (e.g., NF Service Instance, NF Service Set, NF Instance, NF Set) is introduced. In exemplary embodiments, a recovery timestamp in a restart notification related to the restart of a NF Service provider or NF consumer is associated with the NF Service provider or NF consumer corresponding to the binding level of session contexts served by the service provider or NF consumer. The NF Service provider/consumer may be a NF Service Instance, NF Service Set, NF Instance and NF Set. In the case of a failure, the recovery timestamp populated in a recovery notification is matching the binding level of session contexts which will be affected by the failed NF Service provider/consumer. The recovery timestamp may be included in indirect signaling via a NRF and in direct signal between NFs. Further the recovery timestamp can be included in the header of a restart notification or in a message body of the restart notification. The restart notification may be a service request/response, notification request/response, or a Subscription request/response.

Abstract: Disclosed herein is a method by an AMF node 120-4 operative in a 5GS that comprises a UE 112 associated with a Subscriber Permanent Identifier (SUPI) that is associated with subscription data of the UE. The method comprises: sending towards a SMF node, a request relating to a PDU Session of the UE and comprising a Request Type that is set to Existing PDU Session; and receiving from the SMF node, a response comprising a Generic Public Subscription Identifier (GPSI) of the PDU session, which GPSI is associated with the SUPI and which GPSI is to be used in networks outside the 5GS for addressing the subscription data of the UE.
