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.
Claims25
A method in a mobile device comprising:
- upon determining that the mobile device has moved from a first QoS (Quality of Service)-aware system in which there is at least one first QoS flow reserved for the mobile device, to a second QoS-aware system:
- requesting de-allocation of at least one second QoS flow in the second QoS-aware system;
- initiating reservation of at least one third QoS flow in the second QoS-aware system.
A mobile device comprising:
- at least one wireless access radio;
- at least one antenna;
- a QoS flow re-establisher configured to:
- determine whether the mobile device has moved from a first QoS-aware system in which there is at least one first QoS flow reserved for the mobile device, to a second QoS-aware system;
- upon determining that the mobile device has moved from a first QoS-aware system in which there is at least one first QoS flow reserved for the mobile device, to a second QoS-aware system:
- request de-allocation of at least one second QoS flow in the second QoS-aware system;
- and
- initiate reservation of at least one third QoS flow in the second QoS-aware system.
