Introduction...................................................................................................................................................................................................................................

Purpose

The Alcatel-Lucent 9365 Base Station Router Femto, or BSR Femto, addresses the

residential market. The BSR Femto provides a 3G access point integrated into aresidential gateway to allow operators to create bundled services in a fixed-mobile

convergence setting.

BCR 2.1 is the first BSR Femto commercial release. The solution is based on a flat IP

architecture using a residential W-CDMA unit coexisting with a DSL gateway. The

BSR Femto unit consolidates the UTRAN functions.

Architecture................................................................................................................................................................................................................................

Overview

The BSR Femto solution is made up of a group of home BSR units 3G access point

designed for in-building home use plus a small set of core network elements forinterconnection to the legacy 3G core network.

The solution is fully 3GPP compliant. The following figure shows the high level

architecture of the BSR Femto solution, with an Iu-CS and Iu-PS interface to the

legacy MSC and SGSN respectively:

The core network elements that interconnect to the legacy network constitute the BSR

Gateway cluster and are described in the topic BSR gateways (p. 2-9).

Benefits...................................................................................................................................................................................................................................

Overview

The benefits of the BSR Femto solution are multiple, both for the consumer and for

the operator.

Benefits to the consumer

Benefits to the consumer include:

One phone, one bill.

Bundled price plans including discounted or free calls in the home, with no need

for separate bills, accounts, sign-on procedures or a fixed telephone.

Use of standard 3GPP UMTS mobiles: one phone with one number at home and on

the move. A wide range of mobiles is available today.

Multiple simultaneous users in the home. 3G in the home, allowing access to new services above and beyond a 2G solution.

HSPA provides speeds comparable to WiFi. The 3G handset can offer IPTV and

may be connected to other devices such as cameras (for video surveillance), local

PBX (for multiple ringing), and local interphone.

Reduced interference due to use of licensed spectrum, leading to improved voice

quality

Benefits to the operator

Benefits to the operator include:

Fixed-mobile convergence fixed line substitution. 70% of calls are madeindoors, but only 2% of buildings have purpose built indoor coverage.

Bundling with DSL (ISP) allows the operator to be a converged service provider

(MSP + ISP + VoIP) including applications (Triple- or Quad-Play). .

Indoor coverage with low CAPEX the subscriber provides the DSL line. In

addition, indoor QoS is improved while investment in infrastructure is reduced.

Defence against independent VoIP services.

An alternative to cheap at home tariffs which consume macro cell capacity and

leak to an area of a kilometre or more from the home.

Driving UMTS adoption and usage in the macro network boosts enrichedmobile data services such as video telephony and mobile TV.

Enabling scalability to match demand Femto cell coverage is deployed exactly

where and when the consumer needs it. No need to wait for a network rollout of

modified RNCs and SGSNs to relieve bottlenecks.

Use of standard 3G interfaces.

Feature description

The elements that make up the BSR gateway cluster are depicted in the following

figure:

BSR Signalling Gateway

The BSR Signalling Gateway (BSG) mediates signalling between individual BSRs and

the legacy peer UMTS network elements. It provides Iu-CS (to 3G-MSC) and Iu-PS

(to SGSN) interfaces. The BSG also provides other services (for example, paging

support).

It has the following functions in BSR network architecture:

Hides the number of BSRs from UMTS macro networks

Interworks between ATM/IP based SS7 transport and IP transport within the cluster

Message distribution within the BSR cluster

A BSR cluster contains one BSG and supports up to 64 000 BSR Femtos (see 64 000

BSR Femto / BSR gateway cluster (p. 9-4).

The same physical network element hosts the BVG, BPG, IPSec router and networkfirewall. This network element is the Alcatel-Lucent VPN Firewall Brick. Theses

functions are described below. For the network firewall, see Network firewall

(p. 11-7).

BSR Voice Gateway

The BSR Voice Gateway (BVG) is a functional element in the BSR network solution

for support of the user plane for circuit switched voice and data. The BVG provides a

concentration function for the Iu-CS user plane packets being carried on IP. It performs

port and address translation to enable routing to and from multiple associated BSRs.

BSR Packet GatewayA BSR Packet Gateway (BPG) acts as a concentrator for the Iu-PS interface for a BSR

cluster, presenting a single IP address towards the SGSN from the virtual RNC

represented by the BSG and BPG. It performs port and Tunnel Endpoint Identifier

(TEID) translation to enable routing to and from the BSRs. Depending on the number

of BSRs in the cluster, several BPGs may be deployed in each BSR cluster.

Firewall and IPSec router

The network firewall protects against malicious attacks and the IPSec router terminates

a secure tunnel to each BSR Femto.

The following traffic passes through the tunnel: All signalling traffic to and from the operators network elements to provide

security across the managed IP transport network

User plane traffic

OAM traffic

The ALSMS (Alcatel-Lucent Security Management System) provides management for

the Brick product. The rest of the elements included in the BSR Femto architecture

as depicted in the figure above are the optional IuCS Protocol Converter (IPC) and the

standard Authentication, Accounting and Authorisation (AAA) server, Network timing

protocol (NTP) server and ATM switch.Iu-CS protocol converter

The Iu-CS protocol converter (IPC) is needed only if an ATM based Iu-CS interface to

the core network is required. In this sense it is optional, since the BSG and BVG

provide a 3GPP compliant Iu-CS over IP interface.

The IPC is a functional element in the BSR network solution for support of circuit

switched voice and data. The IPC provides a conversion function to enable a BSR

cluster to be connected to a 3G-MSC using the Iu-CS over ATM interface. One IPC is

required per BSR cluster, that is, per Iu-CS interface.

Standard network elements

Alcatel-Lucent 77x0

Authentication, Accounting and Authorisation (AAA) server

Network Timing Protocol (NTP) server

Alcatel-Lucent 77x0

The Alcatel-Lucent 77x0 is a standard ATM edge router to perform IP over ATM

encapsulation, to enable a BSR cluster to be connected to an SGSN using Iu-PS over

an ATM interface. The 77x0 can also be used to aggregate STM-1 based ATM links

and provide an automatic protection switching function for higher reliability. This

solution can be used on both Iu-CS and Iu-PS interfaces on the ATM links from the

3G MSC and SGSN.

Any ATM edge router that supports RFC 2684 can perform these functions. The

Alcatel-Lucent 7710 SR or 7750 SR products can meet this need. These products have

a specific management solution in BCR 2.1.

Authentication, Accounting and Authorisation server

The AAA server is a standard AAA server with specific BSR Femto software. The

AAA server provides the BSR Femto authentication function for the BSR cluster.

When the BSR Femto requests access to the network, it first creates an IPSec tunnel to

the IPSec router. This then requests the AAA to authenticate the request using a

RADIUS interface to the AAA server.

The AAA must be provisioned with sufficient information to authenticate the Femto,

for example, serial number. In addition, location information can be provided which

allows the AAA server to check whether the BSR Femto is still at the same location.

Other checks are performed by the BSR Femto (for example, based on the RF

environment) to determine whether the location has changed.

The AAA server functionality is provided by the VitalAAA product with a specific

EAP plug-in to authenticate the Home BSR.

Network timing protocol server

the NTP server provides the timing solution for the BSR Femto to keep the internal

oscillator trained to the correct accuracy. The server transmits NTP packets to keep the

BSR Femto synchronized with the network time.

The NTP solution offered is the Brilliant Zurich Z-1000 NTP server and is specific to

the timing solution provided in the Home BSR. Another NTP Server that meets the

requirements may be used.

Support of location based services (RANAP signalling)................................................................................................................................................................................................................................

Feature number


Feature description

The BSR Femto supports the RANAP location report procedure. This standard

procedure is initiated by the MSC to request the location of a particular UE from the

RNC (that is, in this case, from the BSR Femto).

As the radius of the BSR Femto cell is very small, the location of the Femto BSR and

the UE can be considered coincident. The BSR Femto therefore reports the location of

the Femto cell as the location of the UE.

During auto-configuration the HNMS system provisions the BSR Femto with its

geographical coordinates (latitude and longitude) and cellid. The operator back officesystem provides these geographical coordinates to the HNMS. The position informatio

is reported in fully standardised formats, based on this data.

Possible location formats are:

Geographical coordinates.

Service Area Identifier (SAI). This includes cellid and LAC/RAC.

This location information may be requested to the MSC and reported to a client

application associated with the UE, or by a client within or attached to the core

network. It can also be requested for an emergency call.

Feature benefits

The location of the UE caller can be provided to emergency services to assist in their

response. This service is mandatory in some jurisdictions, such as the United States,

where it is mandated for all mobile voice subscribers.

The feature also allows new value added services to be introduced.

HSDPA support...................................................................................................................................................................................................................................

Feature number


Feature description

The BSR Femto supports the establishment of a PS RAB on either HSDPA or DCH

based on UE capability. If the UE is HSDPA capable, then the PS RAB is established

on HSDPA.

HSDPA access is a service based on a pool of potentially high-throughput downlink

channel resources shared between a group of users. A scheduler in the BSR Femto

serves users based on traffic, channel conditions, UE capability and QoS requirements.

Techniques such as adaptive modulation and hybrid ARQ are introduced.

The BSR Femto supports the following HSDPA-related functions: HSDPA user plane for HS-DSCH channels and flow control.

HSDPA air interface scheduler providing the requested quality of service

performance.

MAC-hs scheduling.

QPSK and 16 QAM.

The MAC layer of the BSR Femto handles priority control of data flows. MAC-d and

MAC-hs (in the baseband processor) interact to provide proper scheduling and priority

control of data over HSDPA. The MAC-hs scheduler supports multiple MAC-d flows.

The HSDPA scheduler runs every TTI (2 ms).

The BSR Femto supports HSDPA terminals with categories 1 to 12 subject to a peak

data rate. The BSR Femto ensures that the peak HSDPA rate provided to each terminal

will be compatible with their supported category and within the capacity of the

baseband modem.

Feature benefits

Benefits for users

Significant increase of user-perceived data throughput, which is needed to support

multimedia services for cellular mobile communication systems. Reduced delay in signalling and data transport as a result.

Benefits for service providers

Improved capacity and efficiency.

Increased aggregated cell throughput.

Ability to offer attractive services such as high quality streaming video.

features

Overview................................................................................................................................................................................................................................

Purpose

This chapter describes the BSR Femto features that are related to Radio Resource

Management (RRM).

Radio Resource Management

The main task of RRM is to administer the radio connection and radio bearers in orde

to provide different types of services. RRM enables efficient use of BSR Femto

resources such as spectrum, power and code space. It also optimises system stability

and provides overload protection.

RRM functions include:

Call admission control.

Establishment, maintenance and release of the RRC connection. Reconfiguration and release of radio bearers.

Power control.

Overload control.

Dynamic bearer control...................................................................................................................................................................................................................................

Feature number


Feature description

Call admission control admits or denies RRC connection requests based on the number

of Cell DCH UEs currently present in the BSR Femto (maximum of 4) and a Dynamic

Bearer Control (DBC) check. The DBC process is responsible for the rate allocation

for PS services and CS conversational services on DCH and/or HS-DSCH transport

channels, based on baseband processor resource usage. DBC admission control ensures

that the baseband processor resource usage is not exceeded when admitting a new PS

or CS RAB.

The number of UEs and their associated RABs determine the resources used by the

BSR Femto.

The BSR Femto performs the following steps when it receives a new RRC connection

request:

Step 1

Checks that resources to accept a call are available. That is, the maximum number of

users or maximum total data rate has not been reached (depending on their RAB, as

specified in the table inFour simultaneous CS or PS calls (p. 9-2). If there are

enough resources, the call is set up.

Step 2

If resources are insufficient and there are fewer than four ongoing calls, then the new

call is admitted at a lower data rate. This is provided the new call is a PS data call,

which may be downgraded, and is based on the available resources.

The resource limitation may be on the downlink or the uplink or both. If the limitation

is on the downlink DCH data rate then the BSR Femto renegotiates the downlink DCH

rate down and rechecks whether the admission criteria are satisfied. Limitations apply

only to the data rate of downlink DCH bearers, not to HSDPA.

The new PS data call is renegotiated as follows, according to the RABs supported in

BCR 2.1:

UL 384 / DL 384 Kbit/s is downgraded to UL 128 / DL 128 Kbit/s.

If the limitation is on the uplink data rate then the BSR Femto renegotiates the uplink

DCH rate down and rechecks whether the admission criteria are satisfied. The new PS

data call is renegotiated according to the RABs supported in BCR 2.1. RABs are listed

in topicFour simultaneous CS or PS calls (p. 9-2)

The new PS data call is renegotiated as follows:






For downlink on HSDPA, the RABs will become:

UL 384 / DL on HSDPA is downgraded to UL 128 / DL HSDPA.

UL 128 / DL on HSDPA is downgraded to UL 64 / DL HSDPA.

If the limitation is on both the uplink and the downlink, then the BSR renegotiates the

uplink and downlink rates down and checks if there are enough resources available.




Step 3

If the previous renegotiation attempt fails or if the new call cannot be downgraded (CS

speech 12.2 or CS data 64/64 or interactive/background 32/32), then the BSR Femto

attempts to reconfigure the existing PS RAB with the highest DL / UL DCH rate and

to set its DL / UL DCH rate to the next lower rate. After successful reconfiguration of

an existing PS RAB, the BSR Femto will retry the new incoming RAB.

Step 4

If there is still no spare capacity in the BSR Femto and the data rate of the existing

calls cannot be negotiated down further, then except for emergency calls, the call is

denied.

Step 5

If there are no existing PS RABs to downgrade and the voice call is an eme
