Abstract
A data stream transmitting and receiving method and apparatus guaranteeing quality of service (QoS), in which the data stream transmitting method includes obtaining information regarding a link characteristic change of a mobile node, which occurs due to a handover of the mobile node between heterogeneous links, and transmitting the data stream to the mobile node based on the obtained information. Accordingly, even when the handover of the mobile node between heterogeneous links is performed, QoS of the data stream can be guaranteed.
Claims29
A method of transmitting a data stream, the method comprising:
- obtaining information regarding a link characteristic change of a mobile node, which occurs due to a handover of the mobile node between heterogeneous links;
- and
- transmitting the data stream to the mobile node based on the obtained information regarding the link characteristic change.
An apparatus transmitting a data stream, the apparatus comprising:
- a handover function layer obtaining information regarding a link characteristic change of a mobile node, which occurs due to a handover of the mobile node between heterogeneous links;
- and
- an upper layer transmitting the data stream to the mobile node based on the obtained information.
A computer readable recording medium storing a computer readable program for executing a data stream transmitting method on a computer, the method comprising:
- obtaining information regarding a link characteristic change of a mobile node, which occurs due to a handover of the mobile node between heterogeneous links;
- and
- transmitting a data stream to the mobile node based on the obtained information regarding the link characteristic change.
A method of receiving a data stream, the method comprising:
- providing information regarding a link characteristic change of a mobile node, which occurs due to a handover of the mobile node between heterogeneous links;
- and
- receiving the data stream transmitted based on the provided information.
An apparatus receiving a data stream, the apparatus comprising:
- a handover function layer providing information regarding a link characteristic change of a mobile node, which occurs due to a handover of the mobile node between heterogeneous links;
- and
- an upper layer receiving the data stream transmitted based on the provided information.
A computer readable recording medium storing a computer readable program executing a data stream receiving method on a computer, the method comprising:
- providing information regarding a link characteristic change of a mobile node, which occurs due to a handover of the mobile node between heterogeneous links;
- and
- receiving the data stream transmitted based on the provided information.
An apparatus transmitting a data stream, the apparatus comprising:
- a lower layer performing a handover of a mobile node between heterogeneous links;
- a handover function layer supporting the handover of a mobile node between the heterogeneous links and obtaining information regarding a link characteristic change of the mobile node, which occurs due to the handover between the heterogeneous links;
- and
- an upper layer transmitting the data stream to the mobile node based on the obtained information.
