  • Method and system for handling QOS flows when moving between systems
    Patent number: 8638752
    Abstract: When a mobile device moves from a first QoS-aware system to a second QoS-aware system, QoS flows may or may not be moved properly. To deal with this, the mobile device requests de-allocation of flows in the second QoS-aware system, and then initiates reservation of flows in the second QoS-aware system. After this, the mobile device will know for certain which QoS flows exist in the second QoS-aware system and can behave accordingly.
