In-bound to Korea Test (1)

• J-user in K-NW (MO) to J-user in J-NW(MT)

• Test Item Location update, Voice/Video call
• Objective Inter-working test of VMSC and
  H-HLR MO call test for inbound roamer

12
In-bound to Korea Test (2)

• K-user in J-NW (MO) to J-user in K-NW (MT)

• Test item Location update, Voice/Video call
• Objective MT call test for in-bound roamer

13
Out-bound to Japan Test (1)

• K-user in J-NW(MO) to K-user in K-NW(MT)

• Test item Location update, Voice/Video call
• Objective Inter-working test of H-HLR and VMSC
  
• MO call test for out-bound roamer

14
Out-bound to Japan Test (2)

• J-user in K-NW (MO) to K-user in J-NW (MT)

• Test Item Location update, Voice/Video call
• Objective MT call test for out-bound roamer

15
Roaming Test Result

• Average measurement values

16
Sharing Experience

• Inter-Working Test between Core Networks
• IOT of LGE UE and Ericsson RAN
• Bearer Capability for Video Call

17
Sharing Experience (Inter-working test)

• Inter-working test between CNs
• UDT and XUDT of authentication vectors
• Case when requesting send-authentication-informa
  tion
• LGE-HLR sends authentication vectors with XUDT
  format, but Ericsson-HLR sends authentication
  vectors with UDT format
• So, VLR received only one authentication vector
  in case that Segment indicator configuration of
  the message is off
• Segment indicator parameter was changed
  to receive 5 Authentication vectors
• It could be happened between operators have
  different message transfer unit

Send-authentication-info ( segment off)
MSC/VLR (LGE)
HLR (Ericsson)
1 authentication vector
Send-authentication-info ( segment on)
5 authentication vector
18
Sharing Experience (Inter-working test)

• Parameter sequence of abort message

• At first, not recognized by LGE MSC/VLR.
• LGE are currently compatible with two cases.

19
Sharing Experience (IOT of UE)

• IOT of LGE UE and Ericsson RAN
• Both voice and video calls were successful in
  first attempt
• ? However, some bearer capability s/w
  patch for video call was required
• Long initial Cell searching time
• Due to large 60MHz spectrum range (2110 2170
  MHz) and small search raster (200kHz) ? Longer
  delay than GSM/CDMA
• After initial search, subsequent searches were
  quickly made
• Need to optimize cell searching algorithm in MS
  for roamers to reduce cell search time
• Ciphering integrity function
• CI function was switched off due to a
  non-support by LGE Handset with Qualcomm chipset
  and s/w AMSS 3.0
• To be supported by Qualcomm AMSS 5.0 within this
  year

20
Sharing Experience (BC of Video call )

• Bearer Capability for video call
• PLMN BC of MS and MSC
• MS and MSC were configured with different
  Parameters
• Rate adaptation(11) and Other Rate adaptation(
  01) were changed (reference TS24.008, TS27.001)
•  

21
Sharing Experience (BC of Video call )

• Bearer Capability for video call
• Translation of PLMN BC ? ISDN BC
• No problem due to exchange of the BC information
• Reference 3GPP TS29.007, TS23.910

22
Other Issues

• VT call between 3G and 2G (GSM/CDMA)
• Results in an abrupt call disconnection
• ? Announcement of terminating MSs VT
  unavailability needs to be provided to
  originating MS
• ? Or, automatic service re-negotiation
  for voice call
• IREG Test document update is needed for new 3G
  services
• Video Telephony
• Location service
• GPRS services (VOD, SMS, etc.)
