Peretz's Action Item from last conf meeting
3.3 QoS:
The standard shall provide a means for obtaining QoS information of each network
involved in the handover process. There shall also be means to translate QoS
attributes of the source system into normalized link-layer QoS levels of the
target system. In other words, a normalized translation attempting to match the
different QoS attributes of the disparate media access technologies shall be
performed so that the migrating session can sustain its QoS attributes during
and after the handover. As an example, matching will be required if users on a
802.11e WLAN system handover sessions with 8 priority levels to a WiMax system
supporting 4 priority levels. The standard shall provide the means for
obtaining the admission control decision so that proper matching can be made.
During handovers, if the target network is unable to support the QoS levels of
the serving network, the handover policy may not preclude the degradation of the
QoS level of the session in the new network for the sake of maintaining a
session continuity.
Section 6.1: attached drawing change per Michael W. comments
Section 6.2.21 third paragraph
Eric is this more acceptable? feel free to amend further before the face-to-face
meeting which I will miss.
In UTRAN, Service Access Points (SAP) are used for communication among all the
sublayers. Layer 2.5 triggers may already be supported in the PHY layer (e.g.
RSSI threshold crossing) and can be easily obtained through a newly defined SAPs
or APIs. Other triggers or hints may be also supported across the UTRAN MAC, RLP
and RRC layers and can also be provided through new or existing SAPs.
Alternatively a new 2.5 layer could be introduced below the UTRAN network
interface and exchange information through new SAPs with all the sublayers. This
concept is captured below. This requirement document is not attempting to
redefine the 3GPP architecture but rather proposes new SAPs that in effect
provide the required layer 2.5 functionality while enabling MIH across
heterogeneous networks.
