First Claim
Patent Images
1. A method for providing services with guaranteed Quality of Service (QoS) in an IP access network, comprising:
- a. a service entity at the network service control layer obtaining the addresses of the calling subscriber and the called subscriber and QoS requirement for the service through analyzing the service request, then applying for network resources to corresponding access network;
b. the edge router of said access network judging whether enough resources can be provided for this service according to the current resource condition, if so, executing step c, otherwise rejecting the service request of the subscriber; and
c. if there are upward traffic streams of the access network in this service, said edge router informing an access network end device of the QoS requirement for the service, the access network end device processing said traffic streams according to the QoS requirement;
if there are downward traffic streams of the access network in this service, said edge router setting priority in access network for this service and forwarding said traffic streams.

Abstract
The invention discloses a method for providing services with guaranteed Quality of Service (QoS) in an IP access network. In this method, when the network control layer applies for network resources to the access network as response to the service request of needing guaranteed QoS, the edge router determines whether the access network can provide enough resources for the service. If there are enough resources, the edge router sends QoS parameters to the access network end devices which make QoS control to get a guaranteed QoS.
