Matthew
read and
made notes in

the
document
reflecting the following feedback
and discussion from the participants
:


Cancel next Wednesday’s meeting Apr 1, make next teleconference for the following
week

(TBD). There was a request for future meeti

doc
is

early May

Use CDMA to eliminate confusion



May not define all the standards



Call all

3GPP2


CDMA
, i
nclude 1X and EVDO



C
on
vention is CDMA2000 to replace 3GPP2



For the entire document GSM/WCDMA, 4G will be 3GPP



Shouldn’t 4G be LTE? Later will add Wimax



Avoid 4G



In
the d
efinition
for this document,
CDMA refers to all these techologies (1X
,
EVDO)


Table 2
-
10




Replace 3GPP2 with CDMA



LTE is a special case
-
needs to be kept separate



Include Legacy but separate LTE as a new network type



Operators don’t want subscribers not to include GSM in network selection side
that’s why they should be toget
her
-
therefore LTE should be lumped together
with
others.


Table 2
-

What is purpose of table
? Answer:
Network settings for end user



3GP
P

technologies as one system



3GPP side there’s hand up/down protocol for HSDPA, WCDMA but must be able
to select LTE

only so user
can

use the phone in Africa or a different region where
only
GSM is available



Allow manual selection or automatic selection



See PRMN table for network in a certain region



For manual Disable should there be a distinction for LTE and GSM
?



Can d
isable manually then PRMN will decide, so the table is ok



If you disable CDMA the user mus
t

use what is on the PLMN list



Does user need o choose 3GPP mode or just go to list for manually disabled
?



LTE device roams where it is available as well as WCDMA and

GSM but is
expensive in region
-

just
may
want GSM and WCDMA to choose



UMTS and GSM coverage in Europe GSM and UMTS

you can decide to choose

which

network



Maybe in future LTE will be a choice


For table 2
-
10

GSM/WCDMA/LTE Combine all 3 columns into one



I
f Verizon uses this document they won’t want users to choose



Simplify implementation for Verizon not concerned with CDMA/GSM but
LTE/GSM



Stick to original plan classification



User of doc as a guideline requirement



Only group into 2 categories but don’t hav
e to support them all



In different regions where there are different networks can we manually choose?



Follow what is in 3GPP and leave it as is.



There are two different things: selection of system and handover



Separate out LTE as a network type



What is th
e difference between CDMA 2000 and CDMA only?



GSM/CDMA 2000



Why should LTE be different? Selection can override



LTE GSM CDMA with no network block
. Might be more flexible to set up as a
third network type. Don’t want to disadvantage CDMA operators.



Roam
ing versus initial system selection



Multimode system selection occurs when po
w
ering up
-
preprogrammed



Follow intrinsic mode
,
Global versus manual



Based on implementation
-
should have two choices



Need input from operators like Verizon as it’s a user expectati
on



Nick from Spr
int will give input later
-
world
mode phone in global selection can
make a network choice
-
automatic/manual



Leave
table 2
-

for input from Sprint and Verizon

Leave in Red pending input
from operators and others



Plan for 2 hours for next tele
conference
