NetHawk M5 for IP-RAN and NSN I-HSPA
2
IP-RAN

• IP technology, such as Ethernet, used for
  transmission of control and user plane in UTRAN
  interfaces as defined in 3GPP Rel5
• Decreases costs in start-up and operation phases.
• Improves scalability, reliability and data
  transport-capacity.
• IP-RAN architecture with RNCs and NodeBs similar
  to normal UTRAN

3
NetHawk M5 for IP-RAN

• Difference in the protocol stacks in Iub and
  Iu-CS as IP transmission is used
• In the Iub the NBAP protocol is carried over
  IP/SCTP stack and framing protocols and L3
  signalling are carried over IP/UDP.
• New NBAP procedures describe
• how IP bearer addresses are
• allocated between NodeB and
• RNC for the user plane.
• Protocols in grey are obsolete
  in IP-RAN case.

NetHawk M5 for IP-RAN (2)

• In the Iu-CS interface the CS speech and data are
  carried over IP/UDP/RTP stack.
• New RANAP procedures describe how IP bearer
  addresses are allocated between RNC and CS core
  for the user plane.
• Protocols in grey are obsolete
  in IP-RAN case.

5
NetHawk M5 for IP-RAN (3)

• NetHawk M5 provides full protocol analysis
  support for IP-RAN interfaces including Iub,
  Iu-CS, Iu-PS and Iu-BC
• Support for new IPC protocol (ITU-T Q.2631.1)
• IP-RAN is supported with all M5 applications
• Call Session Analysis
• Call Session Statistics
• Counters
• IP-RAN is an optional feature in M5 UTRAN
  decoding package.

NetHawk M5 for IP-RAN (4)

• Up to eight Ethernet links can be monitored by
  using the NetHawk D4 Adapters
• Use of NetHawk D4 Adapters for Ethernet
  monitoring is highly recommended as they provide
• Accurate timestamps
• Significantly more capacity and performance
• HW level filtering
• NetHawk D4 C-Lite
• Two electrical 10/100 Mbit and Gigabit Ethernet
  links
• PCI/PCI-X Adapter
• NetHawk D4 G-Pro
• Two electrical or optical 1 Gigabit Ethernet
  links and
  HW level filtering (Note only GB Ethernet
  supported!)
• PCI-X Adapter

7
NSN I-HSPA

• Internet High Speed Packet Access new
  high-speed data technology designed for heavy
  data users over the wireless network
• Simple module upgrade to NSN WCDMA base stations.
• Packet user plane data sent via Ethernet directly
  from NodeB to the GGSN.
• Otherwise the radio architecture of the network
  remains the same.

8
NSN I-HSPA (2)

• Data stream bypasses the RNC and the SGSN and
  offloads directly to the Internet

9
NetHawk M5 for NSN I-HSPA

• NetHawk M5 provides full protocol analysis
  support for I-HSPA Iub interface
• New protocols supported
• UDPCP OBSAI Reference Point 1 v.2.0
• NSN-specific IPC ITU-T Q.2631.1 and NSN
  specification (FlexiTransport Interworking Unit
  Specification for Flexi WCDMA BTS 1.0)
• I-HSPA Dynamic Iub, Call Session Analysis and
  Statistics are also supported in M5.
• Monitoring of up to eight Ethernet links with
  NetHawk D4 Adapters.
• I-HSPA is an optional feature in M5 UTRAN
  decoding package.
