31st October 2007 NetHawk Oyj NetHawk M5 for IP-RAN and NSN I-HSPA

31st October 2007 NetHawk Oyj 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:

31st October 2007 NetHawk Oyj >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

31st October 2007 NetHawk Oyj 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.

31st October 2007 NetHawk Oyj 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 ) >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.

31st October 2007 NetHawk Oyj 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

31st October 2007 NetHawk Oyj 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.

31st October 2007 NetHawk Oyj NSN I-HSPA (2) >Data stream bypasses the RNC and the SGSN and offloads directly to the Internet: BTS RNC SGSN GGSN IP networks Centralised Control and O&M IMS and Service platforms WCDMA base station with I- HSPA unit Iub

31st October 2007 NetHawk Oyj 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 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.
