Abstract
Disclosed are a BS apparatus, a terminal apparatus, and a QoS control method for implementing the service flow-based QoS control without increasing complexity compared to the conventional bearer-based QoS control method.
Claims12
A Base Station (BS) apparatus comprising:
- a determination unit configured to determine service flow for downlink packets to be transmitted to a terminal;
- an identification unit configured to identify a particular Quality of Service (QoS) parameter defined for the service flow from QoS parameters defined for each of service flows;
- a transmitter configured to apply the particular QoS parameter to the downlink packet and transmit the downlink packet to the terminal with particular QoS for the service flow;
- and
- an interworking controller configured to, when the terminal is handed over to another network supporting a QoS control policy different from that of the BS apparatus, provide QoS conversion information for converting the particular QoS parameter into a QoS parameter according to the different QoS control policy to the terminal.

A terminal apparatus comprising:
- an acquisition unit configured to acquire QoS control information from a header of a particular downlink packet of downlink packets received from a Base Station (BS);
- a QoS controller configured to map a particular QoS parameter identified from the QoS control information to a service flow of the particular downlink packet;
- and
- a transmitter configured to apply the particular QoS parameter to an uplink packet of the service flow and transmit the uplink packet with particular QoS defined in the service flow,
- wherein, when a handover is performed to another network supporting a QoS control policy different from that of the BS, the QoS controller converts the particular QoS parameter into a QoS parameter according to the different QoS control policy based on QoS conversion information provided from the BS.

A method of controlling QoS, the method comprising:
- determining service flow for downlink packet to be transmitted to a terminal by a Base Station (BS) apparatus;
- identifying a particular Quality of Service (QoS) parameter defined for the service flow from QoS parameters defined for each of service flows by the BS apparatus;
- applying the particular QoS parameter to the downlink packet and transmit the downlink packet to the terminal with particular QoS for service flow by the BS apparatus;
- and
- providing, when the BS apparatus identifies that the terminal is handed over to another network supporting a QoS control policy different from that of the BS apparatus, QoS conversion information for converting the particular QoS parameter into a QoS parameter according to the different QoS control policy to the terminal.

A method of controlling QoS, the method comprising:
- acquiring QoS control information from a header of a particular downlink packet of downlink packets received from a Base Station (BS) by a terminal apparatus;
- mapping a particular QoS parameter identified based on the QoS control information to a service flow of the particular downlink packet by the terminal apparatus;
- and
- applying the particular QoS parameter to an uplink packet of the service flow and transmit the uplink packet with particular QoS defined in the service flow by the terminal apparatus,
- wherein, when a handover is performed to another network supporting a QoS control policy different from that of the BS, the particular QoS parameter is converted into a QoS parameter according to the different QoS control policy based on QoS conversion information provided from the BS.
