The HTTP request is rejected because the set of information needed by the PCF for UE Policy selection is incomplete or erroneous or not available for the decision to be made.

PENDING_TRANSACTION

400 Bad Request

This error shall be used when the PendingTransaction feature is supported and the PCF receives an incoming request on a policy association while it has an ongoing transaction on the same policy association and cannot handle the request as described in clause 9.2 of 3GPP TS 29.513 [7].

POLICY_ASSOCIATION_NOT_FOUND

404 Not Found

The HTTP request is rejected because no UE policy association corresponding to the request exists in the PCF.

NOTE: Including a "ProblemDetails" data structure with the "cause" attribute in the HTTP response is optional unless explicitly mandated in the service operation clauses.

PENDING_TRANSACTION

400 Bad Request

This error shall be used when the PendingTransaction feature is supported and the NF service consumer receives an incoming request on a policy association while it has an ongoing transaction on the same policy association and cannot handle the request as described in clause 9.2 of 3GPP TS 29.513 [7]. (NOTE 1)

NOTE 1: This application error is included in the response to the Policy Update Notification HTTP POST request.
