System and method for indicating network quality of service capability as a presence attribute of an end-user

摘要

System and method for indicating network quality of service capability as a presence attribute of an end-user are described. One embodiment is an access network for providing quality of service (“QoS”) information of the access network. The access network comprises an Application Quality of Service (“AQS”) device that controls QoS parameters for the access network; a presence server that develops a QoS attribute of an end-user of the access network by collecting QoS attributes of the access network from the AQS device and collecting QoS attributes of an end-user device; and a Session Initiation Protocol (“SIP”) server that communicates with the presence server to collect the QoS attribute of the end-user and communicates the QoS attribute to an edge router of another access network.
