Abstract
The invention relates to a method for determining Quality of Service information of a radio bearer configured in a mobile node and distributing scheduled radio resources to the radio bearer. Further, the invention also provides a base station and mobile node performing these methods, respectively. The invention suggests a scheme that allows for supporting an efficient Quality of Service over the lifetime of a connection, even upon handover of the mobile node between two radio cells. This is achieved by providing Quality of Service measurements upon handover, such as a provided bit rate of radio bearers configured for the mobile node, to the base station controlling the target radio cell, either by the source base station in the source radio cell or the mobile node.

48. A method for determining Quality of Service information of at least one radio bearer configured for a mobile node, said method comprising the following steps performed by a target base station:
-
receiving first information on a Quality of Service parameter of at least one radio bearer upon handover of the mobile node from a source radio cell to the target radio cell controlled by the target base station, said Quality of Service parameter being measured in the source radio cell, and determining second information on the Quality of Service parameter of the at least one configured radio bearer based on the received information on the Quality of Service parameter measured in the source radio cell. - View Dependent Claims (49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65)

-
66. A method for distributing radio resources to at least one radio bearer configured for a mobile node, said method comprising the following step performed by the mobile node:
distributing allocated radio resources to the at least one radio bearer established between the mobile node and a target base station in the target radio cell taking into account information on a Quality of Service parameter of the at least one radio bearer upon handover of the mobile node from the source radio cell to the target radio cell, said Quality of Service parameter being measured in the source radio cell. - View Dependent Claims (67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85)
-
86. A base station for determining Quality of Service information of at least one radio bearer configured for a mobile node, the base station comprising:
-
a receiving section for receiving first information on a Quality of Service parameter of at least one radio bearer upon handover of the mobile node from a source radio cell to a target radio cell controlled by the base station, said Quality of Service parameter being measured in the source radio cell, and a determining section for determining second information on the Quality of Service parameter of the at least one configured radio bearer based on the received information on the Quality of Service parameter measured in the source radio cell.
-
-
87. A mobile node for distributing radio resources to at least one radio bearer configured for the mobile node, the mobile node comprising:
a distributing section for distributing allocated radio resources to the at least one radio bearer established between the mobile node and a target base station in the target radio cell taking into account information on a Quality of Service parameter of the at least one radio bearer upon handover of the mobile node from the source radio cell to the target radio cell, said Quality of Service parameter being measured in the source radio cell.
-
88. A communication system comprising a base station and a mobile node, wherein the base station comprises:
-
a receiving section for receiving first information on a Quality of Service parameter of at least one radio bearer upon handover of the mobile node from a source radio cell to a target radio cell controlled by the base station, said Quality of Service parameter being measured in the source radio cell, and a determining section for determining second information on the Quality of Service parameter of the at least one configured radio bearer based on the received information on the Quality of Service parameter measured in the source radio cell, and the mobile node comprises distributing means for distributing allocated radio resources to the at least one radio bearer established between the mobile node and a target base station in the target radio cell taking into account information on a Quality of Service parameter of the at least one radio bearer upon handover of the mobile node from the source radio cell to the target radio cell, said Quality of Service parameter being measured in the source radio cell.

-
89. A computer readable medium storing instruction that, when executed by a processor of a base station, cause the base station to determine Quality of Service information of at least one radio bearer configured for a mobile node, by:
-
receiving first information on a Quality of Service parameter of at least one radio bearer upon handover of the mobile node from a source radio cell to the target radio cell controlled by the base station, said Quality of Service parameter being measured in the source radio cell, and determining second information on the Quality of Service parameter of the at least one configured radio bearer based on the received information on the Quality of Service parameter measured in the source radio cell.

90. A computer readable medium storing instruction that, when executed by a processor of a mobile node, cause the mobile node to distribute radio resources to at least one radio bearer configured for the mobile node, by:
distributing allocated radio resources to the at least one radio bearer established between the mobile node and a target base station in the target radio cell taking into account information on a Quality of Service parameter of the at least one radio bearer upon handover of the mobile node from the source radio cell to the target radio cell, said Quality of Service parameter being measured in the source radio cell.
