Abstract
A second RAN node (2) associated with a secondary RAT configures a radio bearer of the secondary RAT in accordance with a bearer-level QoS parameter conforming to a QoS framework of a primary RAT. In addition, the second RAN node (2) translates the bearer-level QoS parameter to a flow-level QoS parameter conforming to a QoS framework of the secondary RAT and associates the obtained flow-level QoS parameter with the radio bearer of the secondary RAT.
Claims11
A second radio access network (RAN) node used in a radio communication system that supports dual connectivity involving a primary RAT and a secondary RAT and includes a common core network associated with the primary RAT, the second RAN node being associated with the secondary RAT, the second RAN node comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured to:
- receive, from a first RAN node associated with the primary RAT, a radio bearer setup request indicating a bearer-level QoS parameter conforming to a Quality of Service (QoS) framework of the primary RAT;
- configure a radio bearer of the secondary RAT based on the radio bearer setup request;
- translate the bearer-level QoS parameter to a flow-level QoS parameter conforming to a QoS framework of the secondary RAT;
- and
- associate the flow-level QoS parameter with the radio bearer of the secondary RAT.
A radio terminal used in a radio communication system that supports dual connectivity involving a primary RAT and a secondary RAT and includes a common core network associated with the primary RAT, the radio terminal comprising:
- at least one wireless transceiver configured to simultaneously communicate with a first radio access network (RAN) node associated with the primary RAT and a second RAN node associated with the secondary RAT;
- and
- at least one processor configured to receive, from the second RAN node via the first RAN node, configuration information of a radio bearer of the secondary RAT for the dual connectivity,
- wherein the configuration information includes both a network bearer identifier conforming to a Quality of Service (QoS) framework of the primary RAT and a flow-level QoS parameter to be associated with the bearer identifier and conforming to a QoS framework of the secondary RAT.
A method for a second radio access network (RAN) node used in a radio communication system that supports dual connectivity involving a primary RAT and a secondary RAT and includes a common core network associated with the primary RAT, the second RAN node being associated with the secondary RAT, the method comprising:
- receiving, from a first RAN node associated with the primary RAT, a radio bearer setup request indicating a bearer-level QoS parameter conforming to a Quality of Service (QoS) framework of the primary RAT;
- configuring a radio bearer of the secondary RAT based on the radio bearer setup request;
- translating the bearer-level QoS parameter to a flow-level QoS parameter conforming to a QoS framework of the secondary RAT;
- and
- associating the flow-level QoS parameter with the radio bearer of the secondary RAT.
