Inferring a message type may include applying a set of inference rules to content elements of the message to determine a message type. Various exemplary embodiments further include validating a message received at the PCRN, receiving an incomplete message at the PCRN, and inferring a value of a missing element of an incomplete message. Incomplete messages may include messages where the missing element is a message type element that indicates the type of the message.
