This defines information for a 3rd Generation Partnership Project (3GPP) Cellular Network for hotspots that have roaming relationships with cellular operators.
The 3GPP Cellular Network Profile defines an Access Network Query Protocol (ANQP) information element (IE) to be sent in a Generic Advertisement Service (GAS)
