Establishing sessions with defined quality of service

摘要

The present invention allows different types of communication applications to cooperate with an associated communication client to facilitate communications having a defined quality of service. The communication client may establish an authorized virtual circuit having a defined quality of service through a network using a first session establishment protocol on behalf of the communication application. Once the authorized virtual circuit is established, the communication application may establish one or more communication sessions, which may support different types of multimedia services, through the virtual connection. In one embodiment, the virtual connection extends through the local access network, which may be supported by an IP multimedia subsystem (IMS). The communication client may use the Session Initiation Protocol (SIP) as the first session establishment protocol to establish the virtual circuit through the local access network.

主权项

1. A method for facilitating authorized communications with a defined quality of service through a communications network for a mobile terminal comprising a communication client and a communication application where the communication application is not necessarily configured to use a communications establishing protocol of the communications network, the method comprising:
receiving one or more indications of communication capabilities from an endpoint; based on the received indications, causing the communication client to establish a virtual circuit having a defined quality of service through the network using a first session establishment protocol of the communications network; and establishing at least one additional communication session extending from the communication application and through the established virtual circuit to the endpoint using a communication protocol within communication capabilities of the communication application.
