Embodiments include methods performed by a service consumer network function (NF) of a communication network. Such methods include sending, to a network repository function (NRF) of the communication network, a request for an access token for notifications from a service producer NF of the communication network. The request includes a list of alternative notification endpoints. Such methods also include receiving, from the NRF, an access token for the notifications from the service producer NF. The access token includes the list of alternative notification endpoints. Such methods also include sending, to the service producer NF, a subscription request for the notifications. The subscription request includes the received access token, a primary notification endpoint, and binding information usable for selecting an alternative notification endpoint from the list. Other embodiments include complementary methods performed by NRFs and service producer NFs, as well as network nodes/functions that perform such methods.

Authorization of consumer network functions

A method performed by a network node for handling a communication session in a wireless communication network. The network node receives from a user equipment (UE) a registration message for re-registering the UE to a session. The network node further verifies the registration message based on registration information previously stored for the UE When verified in response to the reception, transmits back to the UE, a registration response along with a terminating request for a call establishment.
