BSC Conceptual Model

Features of the BSC platform

• The main features of the BSC platform are:

– Reliable platform:

• Distributed processing

• Modular structure

• Fault tolerance

• Upgradable processors (Intel family)

– Easy operability:

• Good online operability

• OSI protocol model for O & M functions. user-friendly

MML interface according to ITU-T recommendations

Features of the BSC platform…

• Flexible configuration:

– Expandability in 64 TRX steps from 64 TRXs to up to 512 TRXs

in High Capacity BSC configurations( bsc 2i)

– The modular architecture allows you to build economically

dimensioned switching systems according to your needs,

and it also reduces the cost of surplus capacity and enables

new facilities to be readily added.

• No special room requirements:

– BSCs are small and compact and low on power consumption

– The cooling of the BSC is implemented by means of natural

convection

The Nokia Base Station Controller Product upgrades

• LAN upgrade

This comprises user-friendly connector panels for Ethernet connections from PCU and CPU units for the Lb interface and other IP connections , these include:– Cabling panel to the top of the cabinet

– Cabling from CPUs and PCUs to cabling panel

• (E)GPRS upgrade deliveries– All the deliveries above can include the GPRS upgrade as

optional hardware. The GPRS upgrade delivery is available for all BSC versions. The 2nd PCU upgrade is available for the BSC2i. The second PCU is upgraded to all configured BCSUs as GPRS/EGPRS extension. PCU units can be either first generation or second generation Packet Control Units.

BSC3i 1000 & 2000 – Hardware and FunctionalitySwitched LAN vs. MB

• In MB, at most one message transfer is happening at any given moment

– A single transfer may address several receivers

• With switched LAN, several message transfers may be occurring simultaneously

– A single transfer addresses, most of the time, just a single receiver

– With EMB, most messages are send to both EMB,0 and EMB,1. This is done in order to improve

reliability and is known as mirroring

BSC Signalling Unit

BSC Signalling Unit

The hardware of the BCSU consists of the following modules

Packet Control Unit (PCU)

There are two generations of Nokia PCUs. The first generation PCUs are PCU-Ts

and the second generation PCUs are PCU2-Us in BSC2i. The preferred option in

S12 is the second generation PCU2s.

The PCU unit performs all the data processing tasks that are related to the (E)

GPRS traffic. It implements both packet switched traffic-oriented Gb and Abis

interfaces in the BSC. A PCU includes a microprocessor and digital signal

processors integrated to the same plug-in-unit to handle the tasks. The main

functions are GPRS traffic radio resource management, for example

connection

establishment and management, resource allocation, scheduling, data

transfer,

MS uplink power control, Gb load sharing (uplink) and flow control (downlink).

PCUs must be configured to every BCSU installed, but only the activated ones

are to be used. A similar principle applies to the optional second PCU unit. This

requirement comes from the general N+1 redundancy principle of the fault

tolerant DX 200 Computing Platform.

• Single Antenna Interference Cancellation (SAIC)

• Space Time Interference rejection combining

(STIRC)

• Multipoint A-Interface

RADIO NETWORK PERFORMANCE

Single Antenna Interference Cancellation (SAIC)

(DL Advanced Receiver Performance; DARP)

Benefits:Improves overall network spectral efficiency Improves call quality of SAIC enabled terminals

New Interference cancellation algorithm for single antenna mobiles

SAIC - Concept

• Single Antenna Interference Cancellation (SAIC) algorithms enable interference cancellation at the mobile receiver without the need for a second antenna and thus can improve the spectrum efficiency of GSM networks.

• There are different approaches but most of them can be included in two groups: Blind Interference Cancellation (BIC) and Joint Detection (JD) methods.

– BIC methods only demodulate the desired signal.

– JD methods demodulate both desired and interfering signals.

trade-off between performance and complexity.

• Currently SAIC is standardised only for GMSK modulation (rel6).

Mobile supportis needed

SAIC Benefits

• Improves overall network spectral efficiency

– When SAIC penetration increases, the spectral efficiency can be improved by increasing reuse (with DL Power Control) in downlink limited network

• Increases call quality of SAIC enabled terminals

– Especially valid result when DL Power Control not in use

– With SAIC the terminals perform in quality conditions that would not be good enough for legacy terminals

• DL Power Control not any more usable

• Quality based handovers not possible

• Increases also to some extent call quality of legacy terminals. This happens due to the overall decreased DL interference levels.

SAIC Summary

• Improves overall network spectral efficiency

• Increases the call quality of SAIC enabled terminals, and decreases interference to legacy terminals

• In high terminal penetration rates SAIC enables both call quality to SAIC enabled terminals as well as considerable gain in overall system capacity

• In S12 release the statistics support in networks enable operators to follow up behaviour of SAIC mobiles

When transmitting to a SAIC mobile in this cell, lower BTS transmit power can be used, thereby reducing the interference received by other terminals (both legacy and SAIC capable)

Space Time Interference Rejection Combining (STIRC)

Enhancement for the basic IRC, which is implemented in Nokia EDGE Ultra Site & Metro Site products

Benefits:

Improves overall network spectral

efficiency and quality

STIRC - Overview

• STIRC is a UL Receiver technology (set of Digital Signal Processing Algorithms) enhancement to current IRC Receiver Technology

• STIRC improves interference (Co-channel & Adjacent channel) rejection capability of the EDGE Ultra Site & Metro Site IRC receivers significantly

• (ST)IRC Technology is implement purely by BTS Base band DSP SW– STIRC is supported by EDGE TRX– STIRC is not supported by a Non EDGE TRX

• STIRC supports all forms of RF Hopping (Baseband, Antenna)

• STIRC supports all antenna configurations, but has its best performance in diversity configurations

• STIRC is licensed capacity enhancement Feature– The License is Administered by BSC on a per BTS_Object Basis– If EDGE TRX is not licensed to use STIRC, then it will use the current IRC Technology

STIRC - Benefits

• Capacity Enhancement

– Better Uplink quality (Improved RxQual distributions, in AMR LA higher usage of higher codec rates for example) particularly in high user density\interference limited scenarios

– Better average user data throughput

– Better spectral efficiency

– Improves both traffic and control channel performance

– Less mobile TX power needed for quality based uplink power control

• Reduces the overall interference level in uplink

• Mobile Battery life is improved in interference limited conditions

Multipoint A-interface

Benefits:

Increase the network performance and

scalability, provide fault protection

BSC can be connected to several MSC servers

Multipoint A-Interface - Benefits

With M-point A-Interface BSC can be connected to several MSC servers in order to:

1) Increase the network performance and scalability

– Distribute the network load amongst the serving entities, enables the BSC’s to route information to different MSC’s.

– Reduce the required signaling • As the MS roams Signaling traffic towards HLR and between VLRs is not needed in intra pool-

area location updates

• Inter-MSS relocations are reduced

– The neighboring pool areas can overlap, which allows to separate the traffic into different 2G MS moving patterns. e.g. pool-areas where each covers a separate residential area and all the same city centre.

2) provide fault protection

– Failure in one MSS/VLR does not stop the service in pool-area

– Flexibility to software upgrades/maintenance (MSS/VLR)

Multipoint A-Interface - Routing Mechanism

• Selection of MSC

– When MS attempts location update or attachments to the network, MSC will be selected by BSC serving the area where MS is currently located. Normally MSC selection is based on NRI (NW resource Identifier).

– BSC shall be able to perform MSC selection also when e.g: (a) received NRI is unknown for BSC, (b) there is no NRI or (c) MSC identified by NRI is unreachable. In these cases load balancing between MSSs in the the pool will be taken into account by BSC.

– After NRI assigned, future transactions between MS and MSC are done towards the same MSC

Encode TMSIso that it containsNRI

TMSI(NRI)TMSI(NRI)

NRI: Network Resource Identifier

Multipoint A-Interface - Routing Mechanism

• MSC will be identified with NRI

– Length of the NRI can be from 0 to 10 bits

– NRI is part of the TMSI and it is located to bits 14 to 23 of TMSI.

• NAS (Non Access Stratum) Node Selection function - Assigns specific network resources (of MSC)

– BSC masks NRI out of the TMSI, which is indicated in each initial NAS signaling message

– BSC routes the NAS message to the relevant MSC

– If no MSC address is configured for the requested NRI or if no NRI can be derived (e.g. the MS indicated an identity which contains no NRI) then the BSC selects an available MSC according to CGR (Circuit Group) load of each MSC’s SPC (Signaling Point Code)

Multipoint A-Interface - Failure Cases

• If MSC breaks down, the NRI value(s) belonging to this MSC are mapped to the other available MSCs if load balancing parameter is set in use

– the Load Balancing algorithm will be informed about the fault situation and new mobiles will not be allocated to that MSC any more

– in failure situation existing 2241 SCCP SUBSYSTEM PROHIBITED alarm rises

Note: 1) Multipoint A (Nokia M13)

2) Global CN-ID support in CS Paging (Nokia SG5.1)

Features in this category are related to the

enhanced GSM technologies such as GPRS and

EDGE evolution.

GPRS/EDGE

Features Under Development in BSS12:

• Dual Transfer Mode (DTM)

• Extended Dynamic Allocation (EDA)

• High Multislot Classes (HMC)

Dual Transfer Mode - DTM

Simultaneous voice and data connection

Benefits:

New revenue opportunities with new

applications and enhanced service continuity

with WCDMA

Dual Transfer Mode - Concept

• Dual transfer mode is providing simultaneous circuit switched (CS) voice and Packet Switched (PS) data service in a coordinated manner

• In dual transfer mode, the mobile station is simultaneously in dedicated mode and in packet transfer mode so that the timeslots allocated in each direction are contiguous and within the same frequency

• The CS part consists of a single slot connection, while the PS part can consist of a multislot connection

• Mobile e-mail, MMS and browsing during voice calls

– Enhanced service continuity with GSM/EDGE and WCDMA

• WCDMA offers simultaneous voice and data by nature

– New applications

• Video Sharing

• Mobile net meeting

DTM - State Transitions

• Mobile is in DTM mode when it has simultaneous CS speech and PS data connections

• Entering to DTM mode goes through the dedicated mode– PS radio connection has to be released when entering and leaving Dual

Transfer Mode

– Nokia solution minimizes the outage on downlink data transmission

– 3GPP release 6 allows transitions between PS and DTM (BSS13 candidate)

File based configuration upload for BSS

Speed up configuration change process

File based plan provisioning - Reasoning

Consistency Checking System

Performance of making configuration changes to BSS radio network needs to be improved

• Network element capacity increase (in S12 up to 2000TRXs)

• Network size has grown (more BSCs/BTSs)

• More radio network objects/parameters

More BSCs and BTSs must be configured during the same maintenance window period

Configuration change process must be divided to phases – less work in the activation phase (usually night shift) – preparations can be done in advance in the day shift

Handover enhancement: BSS20117-202• CR90 improves internal handovers

• CR90 is not direct TCSM3i feature. TCSM3i offers new pools where CR90 is needful.

• There is two kinds of handover types: Internal (handled by BSC) and external (handled by MSC)

• Problem: Noticeable muting in DL direction happens when speech codec ischanged during internal handover but circuit pool remains still the same. (For e.g AMR <-> non AMR). At the present circuit pool is changed in most handover cases and so handovers have automatically been externals.

• CR90 introduces possibility to operator to “force” internal handover to external and thereby avoid DL muting. It also introduces load control on A interface to avoid overload situations.

TCSM3i – Effect on interfaces

• Ater interface– New TCSM type – New circuit types– No support for 8 kbit/s submultiplexing

• A interface – Multirate configuration IE (handover enhancement:BSS20117-202)

• Q3 – New PIU type for event handling– New/ Modified alarms– New parameter for TCSM type (TCSM2/TCSM3i)– New parameter for handover type

• MML– New TCSM type in configuration printout

TCSM3i Reference: Handover enhancement Parameters

• Internal handover to external (IHTA)

– Parameter defines whether it is allowed to change internal handover, where

speech codec or channel rate is changed, to MSC controlled in order to avoid

DL muting.

• TCH transaction count (TTRC)

– Parameter defines how many incoming TCH transactions (incoming MSC

controlled TCH handover or assignment) are taken into account when

calculating average TCH transaction rate.

• Maximum TCH transaction rate (MTTR)

– Parameter defines maximum incoming (from MSC to BSC) TCH transaction rate

(transactions per second) that is acceptable for changing internal handover to

external. In this context TCH transaction means MSC controlled TCH handover

or TCH assignment.
