WAM – WSP association:

• Configuration depends on operator policy

• Trade off between efficiency & security

•1 subrack can have up to 2 WAMs

•1 WAM handles up to 3 WSPs

WSP configuration:

•WSPs provide Baseband capacity for Ultrasite BTS

•All traffic is distributed among available WSPs

• New call assigned to least loaded WSP

• Amount of WSP cards depends on expected traffic

Interesting for Transmission:WSP, WAM, AXC

AXUAXU


WSP - WCDMA Signaling Processing Unit in the Ultra site BTSAs the name WSP describes, it is responsible for signal processing• All traffic coming from the RF part is pooled and distributed roughly

constantly among all available WSP units in the entire Ultra site BTS• The Resource Management takes care for most possible efficient usage of

available WSP capacity• WSP performs a lot of UL&DL functions, such as

– RX and TX code channel processing– Encoding/decoding and fast closed loop power control– Spectrum spreading and Modulation– CRC checking

• There are 2 different kinds of WSP units existing– Old: WSPA, with 32 CE, consisting of four DSP modules with 8 CE each– New: WSPC, with 64 CE, without DSP environment, hence more flexible call

allocation

• Any mixed configuration within Ultra BTS is possible!


The WSP Channel Elements

• Different services require a different amount of Hardware Channels on the WSP card

• Hardware Channel (HWCh) are also known as Channel Element (CE)

• All needed capacity for a specific service must be allocated on the same WSP card

– No channel splitting via different cards, also not under the same WAM

– In case of insufficient availability call request will be downgraded or rejected

• If all types of WSP units were installed in the same WBTS the CCH allocation would follow this priority:

• 1) All CCHs to WSPA• 2) WSPC if WSPA fully loaded or does not

exist• For all HSDPA connections the associated UL-

Channel requires CEs as well– DCH or HSUPA

(* HSDPA allocation depends on the number of HS-PDSCH codes and schedulers per BTS • Module 2 Features for more detailed information

WAM - WCDMA Application Manager

Pooled Baseband SectionTransmission

Section

• A WAM unit has three functional blocks:– Control block performs all O&M and Telecom functions– Interface block (BTS internal bus connection)– ATM block to terminate all ATM connections

• All WAM units perform – Telecom control functions– Logical resource management– ATM processing– Transport channel frame protocol processing.

• Master WAM-unit takes care of the control functions on BTS cabinet level. Those include e.g.

– BTS initialization– Temperature control– Configuration– O&M processing

Behaviour in case of failure: • Any of the Slave WAMs detects the missing Master WAM. • New Master-WAM election starts between remaining Primary WAMs (WAMs in slot Nr.0) • New selected Master WAM resets BTS• After BTS reset a new Master WAM exists during start-up and all Slave WAMs know their role

during start-up• Note: WSP cards corresponding to defect WAM will be taken out of traffic pool

Control Plane - Permanent Signaling linksInterface Control and Signaling Unit (ICSU)Example – an incoming NBAP message is routed within the RNC• Signaling messages sent from the RNC to the BTS

travel in the reverse order.• All internal communication within the RNC is

routed via the ATM switching fabric (SFU)• The signals are usually routed through multiplexers

(MXU), except when they are carried via SDH network interface units (NIS1).

ICSU Functions:• Layer 3 signaling protocols RANAP, NPAB, RNSAP,

RRC and SABP• Transport network level signaling protocol ALCAP• Handover control• Admission control• Load control• Power control• Packet scheduler control• Location calculations for location based services• Redundancy: N+1


Control Plane – Common Control Channels

Example – An uplink Random Access Channel RACH is processed in the RNC• The message is transmitted from the user equipment,

traverses the base transceiver station and arrives at the RNC via a PDH network interface unit (NIP1)

• Since the signaling data between the RNC and user equipment is always carried over AAL2 connections, it must first be demultiplexed in an AAL2 switching unit –A2SU

• Next, the signaling data is sent to a signal processing unit – called DMCU (Data and Macro Diversity Combining Unit) – where protocol processing is carried out. Following protocols are terminated in this functional unit:

– Frame Protocol FP– Medium Access Control MAC– Radio Link Control RLC

• Finally, the actual signaling message – RRC message –is sent to the signaling unit where it is processed.


Control Plane – Common Control Channels

A2SU Functions:• Terminates the AAL2-protocol and sends the data to

the accordant units (DMCU/NIU) for furtherprocessing

• Handles AAL2 CPS minipacket switching• Assembles and disassembles ATM cells• Redundancy: SN+

DMCU Functions:• AAL2 termination • WCDMA L1 functions (MDC, OLPC)• MAC, RLC and PDCP functions• Frame Protocol processing• GTP termination • Encryption• Redundancy: SN+


Control Plane – Dedicated Control Channels

Example – DCCH - Dedicated Control Channel via two RNC’s (Iub, IUr)• In the case of a DCCH, it is possible that the signaling

data is carried between the RNC and user equipment via two or more radio links in parallel

• With the Iub interface, the signaling data is routed to a signal processing unit (DMCU) – as shown previously.

• The Iur interface must be routed to the same signal processing unit (DMCU) – via an AAL2 switching unit (A2SU).

• Both branches undergo Frame Protocol processing in the signal processing unit (DMCU), after which macrodiversity combining is performed

• Signal with the highest quality is selected and sent to the signaling unit (ICSU) for further processing.


User Plane – Signaling Between UE and CS-CN

Example - Data flow in the user plane, starting with circuit switched user data• User data is carried between the user equipment and the RNC

via two radio links in parallel (SRNC, DRNC)• SRNC Iub interface, the user data is routed to a signal

processing unit (DMCU) via an AAL2 switching unit (A2SU). • The user data received via the DRCN Iur interface must be

routed to the same signal processing unit (DMCU) – also in this case via an AAL2 switching unit (A2SU)

• Both branches undergo Frame Protocol processing in the signal processing unit (DMCU), after which macrodiversitycombining is performed and the selected signal undergoes some further MAC and RLC protocol processing.

• One important task of the MAC protocol layer is decryption of the encrypted user data. This is a processing intensive task that only the signal processing unit (DMCU) is capable of performing.

• After macrodiversity combining in the signal processing unit (DMCU), the signal with the highest quality is selected and sent – via an AAL2 switching unit (A2SU) where AAL2 layer multiplexing is performed – and via an SDH-based network interfacing unit (NIS1) – over the Iu-CS interface towards the Mobile Switching Center.

• In the downlink direction, the data flow is in the reverse order. In the signal processing unit (DMCU), the signal is encrypted and sent with some outer loop power control information via the parallel radio links to the user equipment.


User Plane – Signaling Between UE and PS-CN

Example - Data flow in the user plane, starting with packet switched user data• In the case of packet user data transport over a

dedicated channel (DCH) – as shown in the figure – the processing is identical to the processing of circuit-switched user data, only in this case we have assumed that both branches are via the Iub interface.

• After macrodiversity combining and decrypting in the signal processing unit (DMCU), the packet data is sent to – GTPU (GPRS Tunnelling Protocol Unit) – instead of an A2SU unit.

• The GTPU performs IP and UDP protocol processing and guides the packet data into the correct GTP tunnel, after which it is sent via an SDH network interface to the SGSN.


Network Interface

• NIU Network Interface Unit– It processes the physical layer and ATM layer of the incoming/outgoing signal.– NIP: 16 x PDH-IF per unit

available bit rate (ABR) Guaranteed Frame Rate (GFR)


Tellabs 8600 Shortly

• Switching function distributed to line cards– Each Interface card (IFC) brings 3.5 Gbps bidirectional switching capacity

• Combined Control and DC Power Feed Card = CDC– Two variants available CDC1-A and CDC1-B (to be used in sync with IFC variant, IFC-A or B

version)– Can be 1+1 protected

• For Tellabs 8660 and 8630 Tellabs 8600 universal baseboard for interface modules

– Line card consists of one base card (Interface Module Concentrator = IFC) and 1..2 Interface Modules (IFMs)

– IFC has two variants: IFC1-A and IFC1-B▪ IFC1-A: Fully scaleable IFC with 450k IPv4 entries▪ IFC1-B: PWE3 optimized IFC with 256k IPv4 entries

• IFC1-B cost optimized for PWE use

– One Interface module (IFM) can have up to 2.5 Mbps throughput▪ Requires planning which IFMs can be put on the same IFC▪ Not all GE interfaces in 8xGE IFM can be fully utilized

• 4xATM-1 ATM and 8xGE on the same IFC is OK• Fully used 4xSTM-1 ATM is about 600 Mbps and up to 2.5 Mbps can be used for GE interfaces

Protection Mechanisms towards RNC and Packet Network• MSP1+1 for STM-1 ATM interfaces supported towards RNC

– Interfaces need to be on different interface cards at the same module position and port position

• Ethernet link protection (ELP)– May be used to protect network from Ethernet link failures

– When the currently active link is detected to be down, Tellabs 8660 edge switch moves the logical interface (including IP and MAC addresses) from the currently active physical interface to the protecting physical interface

– Protecting interfaces need to be on different interface cards at the same module position and port position


Tellabs 8660/8630/8620Modularity = Flexible Configuration

IFM- various types- density depends on type

IFC- one card for all modules

SFP transceiverfor optics (1..8)also electrical plugs

• Same base board (IFC) can be used for any Interface Module (IFM)

• Two IFMs can be equipped into one Line card

• IFMs fit into any Tellabs 86x0 element

• Number of SFP transceivers can be chosen based on need

The small form-factor pluggable(SFP) is a compact optical transceiver used in optical communications for both telecommunication and data communications applications. It interfaces a network device mother board (for a switch, router or similar device) to a fiber optic or unshielded twisted pair networking cable. It is a popular industry format supported by several fiber optic component vendors.
