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.

RADIO NETWORK PERFORMANCERadio Network Performance related features offer operators advanced functionalities e.g. for the network automation, higher spectral efficiency, network resilience Features in BSS12: Single Antenna Interference Cancellation (SAIC) Space Time Interference rejection combining (STIRC) Multipoint A-Interface

Single Antenna Interference Cancellation (SAIC)(DL Advanced Receiver Performance; DARP)

New Interference cancellation algorithm for single antenna mobilesBenefits: Improves overall network spectral efficiency Improves call quality of SAIC enabled terminals

SAIC - Concept

Mobile support is needed

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).

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-interfaceBSC can be connected to several MSC servers

Benefits: Increase the network performance and scalability, provide fault protection

Multipoint A-Interface - BenefitsWith 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 BSCs to route information to different MSCs. Reduce the required signaling As the MS roams Signaling traffic towards HLR and between VLRs is not needed in intra poolarea 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)

*(Licenced Software)

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 MSCPool area 1 MSS_1 Location Update Attach Procedure (IMSI/IMEI) BSC TMSI(NRI) MSS_2M S C S S PM S C S S P

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 MSCs 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

Enhancements to BSC circuit switched statistics

CS statistic enhancementBenefits: Provide the operator more accurate information for performance management

CS Statistic Enhancement CS Statistic Enhancements consists of improvements to BSC circuit switched statistics. In order to provide the operator more accurate information new counters are added for network monitoring purpose. The new counters are utilized in network monitoring with Nokia Key Performance Indicators (KPIs). KPIs are created to achieve agreed meters in customer networks. New counters include: SDCCH attempts counters: location updates/attempts and fails TCH usage counters: take half rate better into account when calculating busy TCHs

File based plan provisioning - User Workflow1. Plan generation Plan is imported or build in NetAct Consistency checks can be executed in NetAct for the plan Download Selected plan is downloaded to BSCs Review logs in NetAct Validation Cross-checkings in BSCs to ensure that plan is correct for activation Review logs in NetAct Activation Automatic storing of fallback configuration Start activation for selected BSCs Follow the activation progress in NetAct Possible activation of fallback configuration User can activate stored fallback configuration in case of emergency situation

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 is changed 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 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.
