Section: 4.15.7 Network status reporting
Content: This clause contains the detailed description and the procedures for the network status reporting capability. An AF may request for being notified about the network status, in a specific geographical area or for a specific UE. The following methods are supported: - The AF requests to be informed, one-time, about the network status. This procedure is referred to as one-time network status request; - The AF requests to be informed, continuously, about the network status. This procedure is referred to as continuous network status request; The procedure as described in clause 6.1.1.2 or clause 6.1.2.2 of TS 23.288[ Architecture enhancements for 5G System (5GS) to support network data analytics services ]  [50] is used by an AF to retrieve Network Status Result (NSR) from the network for a specific geographical area or for a specific UE. After receiving the request for network status notification from the AF, the NEF retrieves user data congestion analytics information from NWDAF, as defined in TS 23.288[ Architecture enhancements for 5G System (5GS) to support network data analytics services ]  [50]. Based on the user data congestion analytics information the NEF receives from the NWDAF, the NEF derives and reports the network status for the geographical area or for the UE as Network Status Result (NSR) to the AF. When reporting to the AF, the NSR shall not include any 3GPP location information. NOTE 1: Either exact values for congestion status, as reported by NWDAF to NEF or abstracted values e.g. (High, Medium, Low) can be reported by the NEF to the AF. The calculation and the reporting of the NSR to the AF depends on operator configuration (e.g. SLAs, usage etc.). When an AF requests one-time Network Status from the NEF, the NEF can optionally provide a time interval at which the AF is allowed to re-issue the same request for network status. NOTE 2: The time interval provided by NEF can be ignored by the AF if the subsequent request on network status is considerably different with regards to the geographical area or the UE.
