A method, apparatus and computer program for applying a predetermined transmission process to the transmission of IP packets of a particular Internet Protocol (IP) flow in an IP network. The invention is implemented by defining in a host, such as a wireless terminal, a Quality of Service (QoS) management protocol between an IP session management protocol of the host and each of an IP layer and a link layer of the host, and defining in another apparatus, such as a wireless access point, a QoS management protocol between the QoS management protocol of the host and each of an IP layer and a link layer of the wireless access point. The wireless access point communicates with the wireless terminal via a link and allows the wireless terminal to communicate with the IP network. IP session information is configured in the wireless terminal and the wireless access point in each of the IP and link layers based on IP session management information from the IP session management protocol of the wireless terminal. Based on the defined configuration, an IP flow between the wireless terminal and the wireless access point is identified as a particular IP flow. Thereafter, a predetermined transmission process can be applied to the transmission of IP packets of the identified IP flow. |

DETAILED DESCRIPTION The present invention provides an QoS interworking mechanism for mapping IP session management flow information to underlying.
IP and link layers of hosts or other such apparatus in an IP network.
It should be noted that the present invention is particularly useful in wireless IP networks, wherein the hosts are wireless terminal which communicate with the IP network via other apparatus such as wireless access points over a radio link.
However, the present invention can also be applied to other types of networks.
One of the features of the present invention is that after the IP session management information is given to the IP and link layers it is possible to identify particular IP flows (e.
g.
, real-time IP flows) and apply a predetermined transmission process to the transmission of the IP packets of the particular IP flows over the IP and link layers.
The link layer could, for example, be a radio-link layer.
The above feature of the present invention is achieved by defining a generic QoS interface below the IP session management protocols, that together with a QoS management protocol manage the IP network resources.
Therefor according to the above, the present invention provides a method, apparatus and computer program for applying a predetermined transmission process to the transmission of IP packets of a particular IP flow in an IP network, wherein the IP network is connectable to a wireless terminal acting as a host via a radio link and a wireless access point.
The present invention is implemented by defining a QoS management protocol in the wireless terminal between an IP session management protocol and each of IP and link layers of the wireless terminal.
Further, the present invention is implemented by defining a QoS management protocol in the wireless access point between the QoS management protocol of the wireless terminal and each of IP and link layers of the wireless access point.
IP session information is configured in each of the IP and link layers based on IP session management information from the IP session management protocol of the wireless terminal
