Femtocells are low-power wireless access points that:
1. Operate in licensed spectrum
2. Connect standard mobile devices to a mobile operators network
3. Using residential DSL or cable broadband connections.
Forecast: By 2011, more then 100 million users on 32 million access points worldwide.
More realistic estimation: By 2012 more then 60 million users on 32 Femtocells
Femtocells are also known as home base station, Femtocell Access Point (FAP), or home
NodeB (HNodeB).

How operators present the Femtocell?
No matter what network you are on, your mobile signal can sometimes be less thanperfect. Mobile signal issues can be caused by more than just how far you are from
the nearest mobile phone mast. Sometimes they happen because of the location of
the building youre in, or the building type itself. We call these areas blackspots' and
all mobile phone networks around the world suffer from them. They can occur nomatter where you live, even in cities with lots of mobile phone masts ."

In building 3.5-4G subscribers have the
following impact on the network:
1) Consume significant amount of capacity
(bits)
50%-70% of the cellular traffic is
consumed indoors
Most data application are
expected to be used indoors
2) Consume more time/frequency (in 4G)
or time/code resources (in 3.5G) due to
lower link budget. As a result the
outdoor subscribers get less resources.

LTE Femtocell - Architectural Aspects
Since LTE/SAE is based on a flat all-IP architecture, the architecture and
interfaces are the same for femtocells as for macrocells. LTE femtocells (Home
eNodeBs) require no new interfaces to be defined and no changes are required
to EPC elements.
S1-MME MME
HeNB
LTE - Uu
S-GWS1-U
The HeNB can be directly connected to the MME and S-GW assuming that the MME
and S-GW have sufficient capacity to support large numbers of femtocell S1
interfaces.

LTE Femtocell - Architectural Aspects
However new optional element, called the Home eNodeB Gateway (HeNB GW), is
defined to provide aggregation of multiple Home eNodeBs in the core network.
The HeNB GW aggregates S1 interfaces (S1-MME and S1-U), potentially improving the
scalability of the core network in regard to femtocells.

Synchronization
To maintain frequency alignment with the macro cellular
network, femtocells must broadcast at a pilot frequency
with error no greater than 100 parts per billion. There are
efforts to reduce this requirement to 250ppb (3GPP
Home NodeB in Release8). WiMAX Femtocells require 20-
40 ppb accuracy.

Femtocells cannot be used in geographic areas for which the provider
does not have a license to operate a wireless network.

License Verification
Requirements differ by country. In the US, the FCC E911 legislation
mandates identification of the location of the serving cellular base station
(Phase 1), and also identification of the location of the handset (Phase 2).
The degree of accuracy depends on the location technology utilized
(handset-based or network-based). For details, see

Neighbor unpredictability - Dynamic neighboring constellations
FAPs may be added or removed dynamically
Cell prioritization - sometimes required to be against cellular conventions

PSC/PCI Confusion
More than one FAP under macro coverage shares the same Physical Cell Identification
(PSC/PCI). This is a likely scenario in mass deployments of FAPs in parallel to Macro
eNB deployment. The network might thus not be able to do a handover since another
cell with the same PSC/PCI is being reported.

Using a short NCL
Macro Layer
The neighboring cells are identified bytheir PSC/PCI
The FAPs are identified by a PSC/PCI of a
small reserved group (10 numbers or so)
The reserved PSC/PCI group is
transmitted by the Macro BTS and the
FAPs at the vicinity of FAPs
UEs that receive the reserved group try
to search for FAPs identified by aPCI/PCS of the reserved group
This way the UEs do not need to search
for tones of different PSCs/PCIs, the
search time is shorter and batteryconsumption is reduced

LTE UE Neighbors Autonomous Search
-
8/8/2019 !!!Femtocells_Ver_1_1
45/63
45
45Femtocells Technology and Practices
The UE Autonomous Search is an optional feature proposed in Release 8
The purpose of this feature is to enable the UE search for FAPs autonomously
UE Neighbors Search in LTE
The UE does not get an NCL (neighbor list) from the serving cell
The UE is responsible for identifying the neighboring cells
The network only provides the RF carriers upon which to search for
neighboring cells and measure them
UEs are capable of detecting neighboring cells and reporting them to the
serving eNB, using their physical cells identities. The eNB may still target the EU to a Pre- identified neighbor if this neighbor
was pre-defined by the system designer
In Release 8 only CSG FAPs are searched
Next releases will define search of other types of FAPs (e.g. Hybrid, Open).
The conditions of when to trigger the Autonomous Search is left to the UE vendors
implementation

Issues:
All UEs under the coverage of the macro
BTS might start measure FAPs
Solution: A pre verification
method is used. The Network will
provide the Short NCL only to those
UEs which have allowed FAP under
the coverage of the cell
The UE might discover other FAP withthe same PSC/PCI
Solution: post verification based on
CSG ID transmitted by the candidate

CSG
CSG Closed Subscriber Group is a list of the onlysubscribers that are allowed to be served by a certain FAP.
CSG ID is a 27 bit word that defines each CSG in the system
Several FAPs may have the same CSG ID (e.g. enterprise)
Only rel. 8 handsets know what todo with CSG ID
ACL
ACL (Allowed CSG List) lists the CSG IDs
that are open to a certain UE in one ormore FAPs.

When a UE identifies a FAP it is beneficial to know in advance whether the FAP isallowed to the UE and avoid unnecessary communication with the CN. This is doneby using either CSG/CSG-ID or ACL

FAPB NodeB
Most complex one
When entering the building the signal strength of the macro system may be above
a certain threshold, and therefore the FAP will not initiate a search for another
nodeB and will not discover the FAP.
A large number of indoor F-APs may exist in a macrocellneed to select appropriate one from many FAPs
The macro BTS need to transmit the scanning information of all neighbor macro

Step 1: Pre- Determination
The key issue in this phase is finding a way for the RNC to determine which FAP isallowed to the user before negotiating a hand-in and waste time and system overhead.
Reusable scrambling codes
A small number of PSCs (scrambling codes) is reserved for the FAP layer.
When first installed, the FAP scans the FAPs PSCs around and selects oneof the unused PSCs. The FAP then reports the network which PSC it uses.
The same PSCs are reused across all FAPs in the network, creating a virtualFAP layer that is treated just like any other layer in the cell hierarchy.

Determining whether the UE is allowed
Like all cells in the network, each FAP broadcasts its frequency and PSC . When a
UE moves into range of the FAP, it signals the frequency and PSC of the received
FAP to the local RNC and requests a handover.
The RNC adds the users unique International Mobile Subscriber Identity (IMSI) to
the request and sends it via the core network to the Access Controller (AC).
The AC looks up the IMSI in its Access Control list to determine whether the FAP
has this subscriber in its white list (CSG).

The AC requests the FAP to send out a beacon signal on the download syncchannel of the NodeB . The UE detects the beacon signal and responds withthe uplink sync message, and handover proceeds as normal.

Enforcing operation in license areas
Femtocell is licensed to operate only where carrier has licensed spectrum
Femtocell is not in the control of the operator but the user
Operator is licensed to provide service in pre defined geographical areas.
The operator needs to ensure and verify that the Femtocell is located in
licensed area before providing service.
In some countries, a base station must provide location information in
emergency service calls
In most countries the operator most enable lawful intercept of the calls

Lawful intercept
Handled by SA3, TS 33.106 and TS 33.107
Lawful intercept requirements dependent on country of deployment. In broad terms
the following is required:
The network must allow LI of any user on its network, this could be a home
user or a visiting user.
The data must be provided together with decryption keys for the network if
the data is encrypted. Application level encryption keys are collected fromthe service provider.
A user is identified by IMEI or IMSI.
In Europe it also necessary for the network to stored information about the
users history. The data retention directive. Login, movement and amount of
data Requirements on how lawful intercept must be implemented
In order to enable Lawful interception, the traffic should path through the
operators core network
