There is provided mechanisms for event-based reporting from a second NF to a first NF in an SBA network. A method is performed by the first NF. The method comprises sending reporting instructions of events for a session with the second NF. The reporting instructions comprise a list of triggers conditions for each of the events and information of IEs whose values are cached by the first NF for the session. Each of the trigger conditions is associated with its own set of IEs. The second NF is instructed to provide a report to the first NF when one of the trigger conditions is fulfilled at the second NF. The report comprises values of the set of IEs for the event that caused the trigger condition to be fulfilled. The second NF is instructed to include values in the report of those IEs cached by the first NF only if the values have changed compared to the cached values. The method comprises receiving, on an interface between the first NF and the second NF, the report of the event upon the trigger conditions having been fulfilled at the second NF.

There is provided mechanisms for granting network resources for maintaining a communication session for a subscriber in a network. A method is performed by a CTF node. The method includes obtaining, from a gateway in the network, a request for network resources for maintaining the communication session for the subscriber, and requesting, from an OCF node and in response thereto, credit units corresponding to the network resources. The method includes obtaining a grant of the credit units as well as an advance credit indication of additional credit units for the communication session from the OCF node. The method further includes storing the advance credit indication for the communication session and providing, to the gateway, a grant for the network resources for maintaining the communication session in accordance with the obtained grant.

Methods and nodes for maintaining a communication session for a subscriber

A behavior investigating device of a system investigating arrangement in a communication network continuously obtains statistical network usage data of users, analyzes the statistical network usage data with regard to the pattern of behavior of the users, prioritizes the users based on the analysis and informs a traffic prioritizing function about the priority of at least one of the users. The traffic prioritizing function, which may be provided in the traffic prioritizing node, determines that there is network congestion, identifies a communication session of a user in the communication network, obtains a priority of the user from a behavior investigating device and determine whether the user is to be allowed to use the communication network based on the priority and the congestion determination.
