Cross-network quality-of-service verification
View Patent ↗What is disclosed is a system and method wherein a wireless access system configured to receive a data packet with a first quality-of-service indicator value from a wireless device over a wireless link, provide a first level of service to the wireless device over the wireless link based on the first quality-of-service indicator, and transfer the data packet with the first quality-of-service indicator. The communication system includes a core packet network configured to receive the data packet with the first quality-of-service indicator and determine if the first quality-of-service indicator is consistent with a quality-of-service policy for the wireless device. The core packet network is configured, if the first quality-of-service indicator is not consistent with the quality-of-service policy for the wireless device, to determine a second quality-of-service indicator consistent with the quality-of-service policy for the wireless device, and transfer the data packet with the second quality-of-service indicator. The wireless access system is configured to receive the data packet with the second quality-of-service indicator, and provide a second level of service to the wireless device over the wireless link based on the second quality-of-service indicator.

5. The communication network of claim 1 , wherein if the first quality-of-service indicator is consistent with the quality-of-service policy for the wireless device, the core packet network further configured to apply a third level of service to the data packet consistent with the first quality-of-service indicator and transfer the data packet with the first quality-of-service indicator.
6. The communication network of claim 1 , wherein the data packet comprises an IP packet.
7. The communication network of claim 1 , wherein the wireless access system comprises a radio node controller.
8. The communication network of claim 1 , wherein the quality-of-service policy for the wireless device is contained within a user service profile directory.
9. The communication network of claim 1 , wherein the core packet network comprises an IP network.
10. The communication network of claim 1 ,
wherein if the first quality-of-service indicator is not consistent with the quality-of-service policy for the wireless device, the core packet network further configured to encapsulate the data packet and the second quality-of-service indicator in a communication packet and transfer the communication packet containing the data packet and the second quality-of-service indicator to the wireless access system for redelivery.
11. A method of operating a communication system, comprising:
in a wireless device, transferring a data packet with a first quality-of-service indicator over a wireless link;
