QoS channels for multimedia services on a general purpose operating system platform using data cards
A SIP (session initiation protocol) service activation abstraction layer that provides a unified interface to upper layer applications for discovering, establishing, and managing the QoS connectivity. In one implementation, this is IP Multimedia Subsystem-centric, further supporting applications that utilize SIP for session control. This capability extends to the data card universe allowing UMTS data card vendors to establish concurrent QoS-based sessions using multiple primary PDP (packet data protocol) contexts based on a set of SIP triggers, further allowing applications running on a computing system to transparently utilize the established pipes based on the individual QoS requirements.
