  1. www.nethawk.fi NetHawk M5 for IP-RAN and NSN I-HSPA

  2. www.nethawk.fi 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. www.nethawk.fi 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.

  4. www.nethawk.fi 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. www.nethawk.fi 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.

  6. www.nethawk.fi 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. www.nethawk.fi 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. Centralised Control and O&M IMS and Service platforms RNC SGSN Iub IP networks GGSN < Direct connection > BTS WCDMA base station with I-HSPA unit www.nethawk.fi NSN I-HSPA (2) • Data stream bypasses the RNC and the SGSN and offloads directly to the Internet:

  9. www.nethawk.fi 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.
