Method, apparatus and system for NF selection
Methods, apparatus and systems performed and configured to operate in a wireless communication network are presented. In example implementations, a request to register or update a Network Function, NF, profile of an NF in a Network Repository Function, NRF, is sent from the NF to the NRF. The NF profile signaled via the request comprises one or more parameters relating to one or more of a hardware characteristic of hardware comprised in the wireless communication network, a latency characteristic of the wireless communication network, and a throughput characteristic of the wireless communication network. An acknowledgement of the request may be sent from the NRF to the NF.
