Abstract
A method and system supports multilevel QoS (Quality of Service) in transferring a plurality of packets from a local peer entity to a remote peer entity of a communication system, such as a mobile environment using AAL2. During AAL2 Negotiation Procedures (ANP), QoS requirement of each user is obtained either from the user or a computed based on the call setup and is recorded in a ANP memory. After a successful call request negotiation and after a corresponding packet is received by a AAL2 service module, the packet's QoS recorded in the memory is checked. Based on the QoS, the packet is placed into a queue of the AAL2 service module with the same QoS such that a plurality of packets having the same QoS are grouped into the same queue. The packets are transferred from the local peer entity to the remote peer entity based on different QoS requirements.
