A method (200, 300) of tracking remote unit (102, 104, 106, 108) state information. The method can include, for a remote unit communicatively linked to an access service network (ASN) (112, 114), identifying a state change from a first state to a second state. Responsive to identifying the state change, an outbound message indicating the second state can be communicated to a carrier service network (CSN) (110). In another arrangement, responsive to identifying the state change, an indicator that indicates state information associated with the remote unit is available can be published by the ASN or the CSN.
