Abstract
Procedures are provided for robust handling of NAS request messages that contain a spurious information element (IE). The spurious information element could include a NAS message container containing a NAS message with the wrong procedure type, i.e., a procedure type that does not match the type of the parent NAS message. The spurious information elements could also include redundant IEs that are not necessary for the emergency services fallback request.
