This creatable/settable object configures the requested signalling indication for the profile's QoS parameters, flagging whether the traffic on this profile is itself signalling traffic requiring particular handling. An admin sets this to inform the network whether the profile carries signalling-type traffic, which the network may treat differently from ordinary user data for resource allocation purposes. For example, a profile dedicated to carrying VoIP signalling messages might set this indication so the network recognizes and appropriately prioritizes that traffic.
