Dynamic upgrade of quality of service in a packet switched network

A packet-switched telecommunications system, comprising:

• a radio network for communicating signals containing data packets with a mobile user station;
• a core network for routing the data packets and for receiving a request from the user station to route the data packets at a first quality of service level;
• and
• wherein the radio network is operable to allocate system resources for providing a second quality of service level over the radio network and the core network for the data packet routing when system resources for providing the first quality of service level are unavailable, the radio network further operating to allocate system resources for providing the first quality of service level over the radio network and the core network for the data packet routing if the telecommunication system identifies available system resources for providing the first quality of service level during the communication of the data packet signals.

• a core network for routing the data packets and for receiving a request from the user station to route the data packets at a first quality of service level, wherein the core network monitors system congestion to Identify whether system resources for providing the first quality of service level are available by periodically querying the radio network;
• and
• wherein the telecommunications system is operable to allocate system resources for providing a second quality of service level over the radio network and the core network for the data packet routing when system resources for providing the first quality of service level are unavailable, the telecommunications system further operating to allocate system resources for providing first quality of service level over the radio network and the core network for the data packet routing if the telecommunication system identifies available system resources for providing the first quality of service level during the communication of the data packet signals.
