## Abstract

Provided is an apparatus and method for adjusting a bandwidth allocation for a traffic flow associated with a user as a function of a sensed characteristic of the user. A communication device has a sensor data receiver for receiving sensor data pertaining to a sensed characteristic of a user, and circuitry implementing an IRSCU (information representative of the sensed characteristic of the user) messenger configured for sending, to a network entity used for adjusting a bandwidth allocation for a traffic flow associated with the user, a message containing IRSCU. A network management entity, which receives the IRSCU, has circuitry implementing a bandwidth adjustor, which is configured for adjusting, based on the IRSCU, a bandwidth allocation for a traffic flow associated with the user. Accordingly, the bandwidth allocation for the traffic flow associated with the user is adjusted as a function of the sensed characteristic of the user.
