  phases test
• Xueli Zhang, CATR
• zhangxueli_at_mail.ritt.com.cn
• CJK 9th NGN WG Meeting
• April 9-11, Jeju,Korea

2
Scenarios Analysis

• 2 scenarios finished
• Scenario 2 Call Servers across multiple IP
  Network Domains without PSTN
• Scenario 4 Call Servers across multiple NGN
  Network Domains with PSTN
• 5 scenarios left (from 7thNGN-WG_005 and
  CJK6_NGNWG6_17_CJK NGN Test Scenario Proposal)
• Scenario 1 Single Call Server within a single
  NGN Network Domain without PSTN
• Scenario 3 Single Call Server within a single
  NGN Network Domain with PSTN
• Scenario 5 Call Servers across multiple NGN
  Network Domains with PSTN Value Added Services
• This scenario adds Value Added Services to
  scenario 4 using Media Servers and Application
  Servers
• Scenario 6 Performance Evaluation
• Scenario 7 Call Servers across multiple NGN
  Network Domains with PSTN, Value Added Services
  and RACF Involvement

3
Scenarios Analysis

• Scenario 1 Single Call Server within a single
  NGN Network Domain without PSTN

4
Scenarios Analysis

• Scenario 1 Single Call Server within a single
  NGN Network Domain without PSTN

• Test Precondition
• Data configuration SIP, MGCP, H.248 in one
  country connected to Call Server in another
• Test Purpose
• Verify the data configuration?
• Verify the interworking between IAD, TG, SIP
  terminal with Call server
• Usually done by operator to provide service
• Service requirements of our test?

5
Scenarios Analysis

• Scenario 3 Single Call Server within a single
  NGN Network Domain with PSTN

6
Scenarios Analysis

• Scenario 3 Single Call Server within a single
  NGN Network Domain with PSTN

• Same as scenario 1
• Test Precondition
• Data configuration SIP, MGCP, H.248 in one
  country connected to Call Server in another
• Test Purpose
• Verify the data configuration?
• Verify the interworking between IAD, TG, SIP
  terminal with Call server
• Usually done by operator to provide service
• Service requirements of our test?

7
Scenarios Analysis

• Scenario 5 Call Servers across multiple NGN
  Network Domains with PSTN Value Added Services

8
Scenarios Analysis

• Scenario 5 Call Servers across multiple NGN
  Network Domains with PSTN Value Added Services

• Test Precondition
• Which service?
• Test Purpose
• Verify the interworking between call servers
• Same as scenario 2 and 4 we finished except the
  detailed paramter

9
Scenarios Analysis

• Scenario 6 Performance Evaluation
• Network Performance Testing cases
• E2E Call Setup Delay
• Call Completion Rate
• Each Segment E2E IPTD/IPDV/IPLR/Path
  unavailability
• Call Traffic Accounting
• Harmonization Testing of Service QoS class
  differences among CJK
• User Terminal Performance Testing cases
• Various User Terminal Performance Testing

• Test Precondition
• Network
• Simulator
• Call model signalling flow, call duration
• Terminal
• Further study?

10
Scenarios Analysis

• Scenario 7 Call Servers across multiple NGN
  Network Domains with PSTN, Value Added Services
  and RACF Involvement

11
Scenarios Analysis

• Scenario 7 Call Servers across multiple NGN
  Network Domains with PSTN, Value Added Services
  and RACF Involvement

• No RACF, system upgrade
• Huge Cost
• Budget and funding?

12
Other

• IPTV test

• Not support IPTV, system upgrade
• Huge Cost
• Budget and funding?

13
Proposal

• Next step
• Possible scenarios
• Scenario 1 Single Call Server within a single
  NGN Network Domain without PSTN
• Scenario 3 Single Call Server within a single
  NGN Network Domain with PSTN
• Scenario 6 Performance Evaluation for 1,2,3,4
• Our test purpose?
• Funding?
• Common understanding among CCSA members

14
Proposal

• Need preparation after test purpose and scenarios
  are determined
• Test specification first
• Test item
• Data configuration
• Terminal still only SIP in ETRI?
• Service
• Performance Evaluation
• Test specification first
• Call model signalling flow, call duration
• Simulator prepared
• Load traffic generated from one side, terminate
  in other side?

15
Proposal

• Japan?
