Mo-Han,
I do
wonder though, whether there is a potential standards impact. The examples
provided seem to assume that the current anchor will indicate the point in the
data stream, over a backhaul, from which the new anchor should
initiate transmission to the MSS. However, if the MSS is used as a relay
for this information, over the air, we may reduce the inter-BS signaling when
all BSs share (buffer) the same data. Basically, in this scenario, the MSS
informs the new anchor as to the point in the data stream from which data
transfer should continue.

Vasu
PS:
Since I'm joining the discussion late, please excuse any misunderstanding I
might have of the current protocol.
Hi
Jay and Inkyu,
I
echo Mary's reply below.

Hi, Jay nad
Inkyu,
This is Mary
Chion. Sorry about the late reply.
In
FBSS, only one BS will be communicating with the MSS at any time
instance (the anchor BS). The BS can choose one of the BS in the active set
to be the anchor BS through MOB-BSHO-REQ/RSP message. Once the MSS
confirms the HO with MOB-HO-IND, The MSS should only expect trasmission from
the anchor BS.
Regarding the question of which
BS have the data, it's really an implementation issue, it also
depends on what kind of network architecture you will be using. If your
network architecture includes a control point for the BSs (i.e. BSC),
the control point can buffer
the data and only send to current anchor BS. When a new anchor BS is chosen,
the conotrl point will just
redirect the traffic. With distributed system, the anchor BS should be resposible for the data.
When the ahcnor BS is changed, the old anchor BS can forward data to the new anchor BS. The above
scenarios are only examples, the implementatios can be different from each
company and should not be specified in the standard.
Regards,
Mary
To my knowledge, all BS's in an active set share same
data for an MSS.
Am I right?

[Harmonization] Question for FBSS
Dear MO-han
I have a quick question for my
clarification.
I wonder which BSs are responsible for having Data for
an MSS in FBSS(Fast BS Switching).
Do all BSs in active set have to share same data for
an MSS?
OR,
Only a serving BS has data for an MSS then forwards
the data to an anchor BS?
Thanks in advance.
Best
regard.
