Introduction

A femtocell is a small cellular base station designed for use in residential or small business environments. It connects to the service provider’s network via broadband (such as DSL or cable) and typically supports 2 to 5 mobile phones in a residential setting. A femtocell allows service providers to extend service coverage inside of your home - especially where access would otherwise be limited or unavailable - without the need for expensive cellular towers. It also decreases the backhaul costs since it routes your mobile phone traffic through the IP network. Source

A femtocell is sometimes referred to as a “home base station”, “access point base station”, “3G access point”, “small cellular base station” and “personal 2G-3G base station”.

Femtocell

Femtocells are low-power wireless access points that operate in licensed spectrum to connect standard mobile devices to a mobile operator’s network using residential DSL or cable broadband connections.

S.No.	Patent/Publication No.	Title	Problem	Solution
1	US20110047011A1	Incentives to optimize the performance of femto cell groups	The convergence of wireless communication and mobile computing devices continues to spur demand for wireless broadband communication services. As the demand grows, so too must the network infrastructure needed to support wireless communications.	Method of incentivizing an operator of femto cell infrastructure to efficiently utilize the femto cell infrastructure. The method can include establishing, for an end user device, telecommunication network presence on a femto cell. At least one parameter measured within the femto cell can be received. Based on the measured parameter, a determination can be made as to whether to award at least one incentive to the operator of the femto cell, and the incentive can be awarded to the operator.
2	US20110039560A1	System and method for providing access in a network environment	Networking architectures have grown increasingly complex in communication environments. Femtocells have gained recent notoriety due to their capabilities. For many femto scenarios, connectivity and/or access protocols can pose a number of problems for end users.	A method includes evaluating geolocation information associated with a mobile node and using the geolocation information to identify a femtocell capable of providing network access to the mobile node. A primary scrambling code is provided to the mobile node for operation in an idle mode. The method also includes communicating a secondary scrambling code to initiate access to the femtocell by the mobile node when operating in an active mode.
3	WO2011005654A2	Initializing femtocells	Femto access points generally cannot be initiated into an operator’s network, such as a WiMAX network.	The femtocell may be pre-provisioned with certain credentials so that a femtocell access point can authenticate itself to the operator’s network and become attached to that network. The pre-provisioned parameters may include non-operator specific parameters such as the specific credentials for a particular wireless protocol, such as a WiMAX protocol. It may also include operator specific credentials including the fully qualified domain name (FQDN) of a bootstrap server in the femtocell network service provider (NSP)
4	US7855977B2	Alarming in a femto cell network	To efficiently gauging performance of a femto cell network through generation of alarms based on performance rules for aggregated operational data of multiple femto cell access points.	System(s) and method(s) to monitor operation quality of a femto cell network is provided. Operational data received from deployed femto cell access points are aggregated and monitored; aggregation and monitoring take place within a femto cell network platform.
5	US20100309790A1	Femto base stations and methods for operating the same	A major obstacle to using GPS systems to determine and track the location of a femto base station is presented when the femto base station is located indoors because satellite signal penetration indoors is highly unreliable.	The femto base stations and methods to suppress the need for external global positioning system (GPS) antennas and cables, while continually enabling a network service provider to obtain desired position information. It also provide user with the flexibility to place the femto base station at the location of his/her choice within the home or business regardless of GPS signal strength.
6	US20100285812A1	Call admission priority control determination device and mobile wireless communication system	When more than one terminal is present in the same cell and these terminals communicate with one base station, the wireless resources of that base station are shared among the plural terminals. As a result, the communication rate becomes lower than when communication is performed by only one terminal. Thus, there is a problem that the use of the femtocell base station by other users deteriorates the quality of communication by specified terminal users such as the femtocell base station administrator.	It can be solved by a call admission priority control determination device including a registration table containing base station ID numbers of base stations and an ID number of a high-priority first terminal, and a call admission determination unit that determines call admission with reference to the registration table, wherein, when a connection request or a switching-over request for a third terminal has been received from a base station control device, the call admission determination unit, on the basis of this request, references the registration table and determines whether or not call admission for the third terminal is to be permitted.
7	US20100279704A1	Method for controlling access to a mobile communications network	Current 3G redirection features do not allow for redirection of UE’s from a first cell to another cell operating at the same frequency as the first cell. Therefore, if the 3G femtocell is operating at the same frequency as a neighboring 3G RAT or macrocell, then the current redirection mechanism cannot be used for balancing the load. This is due to interference between cells.	For particular femtocells which have reached or are nearing full capacity, a UE such as a mobile telephone or mobile communication device can be redirected from a 3G femtocell to another macrocell operating at the same or different frequency as the femtocell (access point). This provides improved communications for existing users within the femtocell, as well as for new users whose communications have been redirected to another cell.
8	US20100267386A1	Methods and apparatus for facilitating handoff between a femtocell base station and a cellular base station	The resources of a wireless communication system (e.g., bandwidth and transmit power) may be shared among multiple subscriber stations. A variety of multiple access techniques are known, including CDMA, TDMA, FDMA, OFDMA, SC-FDMA etc. Benefits may be realized by improved methods and apparatus related to the operation of wireless communication systems.	A method to facilitate femtocell-to-cellular base station handoff is provided. The femtocell base station may receive a neighbor list from the cellular base station. The neighbor list may include information about other cellular base stations. The femtocell base station may broadcast the neighbor list to subscriber stations that are located within a coverage area of the femtocell base station.
9	US20100177695A1	Technique for interference mitigation using mobile station signaling	MS cannot access the neighboring FBS because the neighboring FBS is a CSG FBS and therefore does not allow access to an unauthorized MS, except for an emergency service. Therefore, the MS falls into a black hole in the network, even though the MS is located within the service coverage area of the FBS it is authorized to receive service from. In worse scenario, the MS is prohibited from sending any signal to the neighboring FBS since the neighboring FBS is a CSG FBS	A method to operate an MS for Interference Mitigation (IM) in a wireless communication system including a plurality of Closed Subscriber Group (CSG) FBSs is provided. The method includes determining if the MS cannot access a first CSG FBS due to interference from a second CSG FBS, the first CSG FBS being a CSG FBS that the MS is authorized to receive service from and the second CSG FBS being a CSG FBS that the MS is not authorized to receive service from, and in the case when MS cannot access the first CSG FBS due to interference received from the second CSG FBS, transmitting an IM-Signal to the second CSG FBS requesting that the second CSG FBS mitigate the interference to the MS
10	JP2010157807A	Communication system, femto cell base station, authentication device, communication method, and communication program	To provide a communication system for assuring communication security in communication between a femto cell base station and an UE.	Communication system is presented which includes: the UE (User Equipment) and an HLR (Home Location Register) to be used in an IMS (IP Multimedia subsystem) network; and the femto cell base station (Femto AP) organizing a prescribed communication area. The femto cell base station (Femto AP) is a communication system existing between the UE and the HLR, to keep the UE confidential through the use of authentication information corresponding to the UE obtained from the HLR when the UE is authenticated.
11	US20100165957A1	Providing a cellular network with connectivity to a different network	An access point in a cellular network for providing a cellular device with network connectivity to a different network.	A System is provided for use in wireless communication which includes a first device communicating via a first protocol in a first network, a cellular device communicating via a second protocol in a cellular network, the second protocol being incompatible with the first protocol, and an access point in the cellular network, the access point being accessible by the cellular device and being configured to enable communication between the first device and the cellular device.
12	US20100135201A1	Registration notification for mobile device management	To notification of registration of a mobile device within femto coverage area for device content management.	A method is presented in which notification is conveyed to a network component or platform that manages firmware content(s) updates when a mobile device for which an update is available, hands off from wireless macro network coverage onto a femto cell coverage. The notification is delivered in response to a firmware update notification delivered to a component that administers location of the mobile device, or an update flag delivered to a femto access point that can provide femto coverage to the mobile device.
13	US20100130212A1	Femto cell handover in wireless communications	Techniques and systems for performing handover of a mobile station between a cellular wireless network and a private cell or private network.	Presented a techniques and systems for performing handover of a mobile station between a cellular wireless network and a private cell or private network which includes operating a macrocell base station to provide wireless service to mobile stations, determining a candidate group of one or more femtocell base station candidates based at least on respective one or more proximities to the macrocell base station to perform a handover of a mobile station that is being served by the macrocell base station, causing the mobile station to take measurements of signals from one or more base stations identified by the candidate group, and selecting a target femtocell base station from the candidate group for the handover based on the measurements.
14	GB2461845A	Femtocell basestation scrambling code selection	The mobile network operator may allocate only a small number of scrambling codes for use by all of the deployed femtocell basestations, and in fact it is possible that there may be only one scrambling code allocated for use by all of the femtocell basestations in an operator’s network, and so there is a possibility that two femtocell basestations that are located very close together may need to use the same scrambling code.	A method for reducing the possibility of interference between femtocell basestations that are located very close together may need to use the same scrambling code which includes method of selecting a scrambling code, for use in a basestation of a cellular communications network, the method comprising: receiving from a management system a list comprising at least one allowed scrambling code for femtocell basestations; and detecting, in information broadcast by at least one macrocell basestation, at least one allowed scrambling code available in an area containing the basestation.
15	US20090286540A1	Femtocell architecture for information management	Congestion in the backhaul network and delays during communication increases because an increase in the number of devices attached to a femto cell, the traffic on the backhaul network of the femto cell can increase significantly	The method presented can facilitate reduction in backhaul network traffic and communication delay by employing an enterprise femto architecture. The enterprise femto architecture employs a routing platform to connect multiple femtos access points to a common femto gateway to generate a mesh network.
16	EP2112854A1	Access control method for cellular networks comprising femto-cells	It is not necessary that the femto system may know at each time the cell locations of all user equipments camping in its area because it will be unable to track those user terminals entering the femto-cell while in the Idle Mode, and also taking into account the fact that up to 6 minutes might be necessary for the user terminal to trigger its periodic location update. Because of this it would not be possible to distribute paging messages from the Core Network to individual femto-cells without running the risk that paging may not be received by the user equipment addressed thereby.	A method is provided to control access of user terminals to a femto system which includes Non Access Stratum (NAS) Mobility Management (MM) messages as well as Access Stratum (AS) Radio Resource Control (RRC) messages.
17	US20090253421A1	Local network management of femtocells	Femtocells could suffer from interference problems without unique spectrum for the femtocell underlay network such as, in a high-rise apartment complex environment, a number of femtocells may be placed near each other, and may be separated only by the floor and/or walls of adjacent apartment units. If these femtocells operate on the same channel, then one femtocell may interfere with the operation of the other femtocell, and vice-versa.	A method to minimize signal interference within a wireless network, the wireless network including a controller communicatively coupled to at least one femtocell, wherein the femtocell is operative to wirelessly transmit and receive data, the method includes: using a portable electronic device to collect signal environment data; analyzing the collected signal environment data; and based on the analyzed signal environment data, commanding the at least one femtocell to alter at least one signal transmission characteristic.
18	GB2456503A	Using global cell identifier for handover in a combined femto-cell/macro-cell environment	When large number of femto cells compared to the number of macro cells is present, it is not possible to ensure that all the femto cells within the coverage area of a macro cell have individual and different frequencies and scrambling codes. So in a combined femto cell-macro cell environment, the macro cell RNC will be unable to determine, from the measurement report received from the UE, which cell (either a femto cell or macro cell) was measured.	A method is provided which includes a network element for a cellular communication system, network element comprises a receiver for receiving a message that comprises a measurement report from a wireless communication unit. The network element further comprises signal processing logic, operably coupled to the receiver, for processing the received measurement report and extracting a global cell identifier therefrom, so the inventive concept provides an improvement to the use of measurement reports, which may be used to facilitate handover between cells in a cellular communication system.

Article Analysis

S. No.	Title	Publication Date	Journal/Conference	Dolcera Summary
1	Cognitive Femtocell	Mar. 2011	IEEE Vehicular Technology Magazine	Because of the fact that femtocells can access a resource, sufficiently and locally, to known users with higher throughput, considerable attention has been devoted to the potential cognitive femtocell to allow for higher capacity and intelligent coverage, with guaranteed quality of service (QoS) for future indoor service. Cognitive femtocell is presented as a solution for spectrum-scarcity problems and local-convergence demands for indoor network applications. To control the data packet delivery between the macrocell and cognitive femtocell, A developed gateway broadband router based on novel cross-layer management optimization is used.
2	Interference Analysis for Femtocell Deployment in OFDMA Systems Based on Fractional Frequency Reuse	Mar. 2011	Communications IEEE Letters	A method of optimal power allocation for femtocells with different orthogonal subbands, based on analysis of macrocell interferences is presented.
3	On-Demand Resource-Sharing Mechanism Design in Two-Tier OFDMA Femtocell Networks	Mar. 2011	IEEE Vehicular Technology Society	Discussed two main design issues in orthogonal frequency-division multiple-access (OFDMA) femtocell networks, i.e., resource sharing and femtocell access control. More comprehensive perspective on self-organizing femtocell networks, where users optimize their performance in a distributed manner is presented.
4	Open vs. Closed Access Femtocells in the Uplink	Dec. 2010	IEEE Transactions on Wireless Communications	Since open access deployment provides an inexpensive way to expand their network capabilities, so it would be preferred by the network operator whereas the femtocell owner would prefer closed access, in order to keep the femtocell’s capacity and backhaul to himself, but best approach depends heavily on whether the multiple access scheme is orthogonal (TDMA or OFDMA, per subband) or non-orthogonal (CDMA)
5	Robust Transmission and Interference Management For Femtocells with Unreliable Network Access	Dec. 2010	IEEE Journal on Selected Areas in Communications	Since each femtocell is served by a home base station (HBS) that is connected to the macrocell base station (BS) via an unreliable network access link, such as DSL followed by the Internet, A scenario with a single macrocell and a single femtocell is presented, and is then extended to include multiple macrocells and femtocells, both with standard single-cell processing and with multicell processing (or network MIMO). Two main issues are presented regarding uplink channel: (i) Interference management between femto and macrocells; (ii) Robustness to uncertainties on the quality of the femtocell (HBSto-BS) access link.

-==Rationale==
-* LTE is the most suited technology as it provides higher data rates required for the future and is an advancement over widely used GSM/EDGE/HSPA
-* A number of corporate giants are looking towards LTE as the technology enabling future communication
-* The following factors are expected to be obtained with the realization of LTE
-** Reduced cost per bit
-** Increased service provisioning - more services at lower cost with better user experience
-** Flexibility of use of existing and new frequency bands
-** Simplified architecture, Open interfaces
-** Allow for reasonable terminal power consumption
-==Background description==
-LTE (Long Term Evolution), is the latest standard in the mobile network technology that came into existence because of the growing needs of faster data rates. It is a 3rd Generation Partnership Project (3GPP), which  realized this technology. LTE is an advancement to previously realized technologies such as GSM/EDGE and UMTS/HSxPA etc.Although LTE is often marketed as 4G, first-release LTE is actually a 3.9G technology since it does not fully comply with the IMT Advanced 4G requirements.
+==Introduction==
+A femtocell is a small cellular base station designed for use in residential or small business environments. It connects to the service provider’s network via broadband (such as DSL or cable) and typically supports 2 to 5 mobile phones in a residential setting. A femtocell allows service providers to extend service coverage inside of your home - especially where access would otherwise be limited or unavailable - without the need for expensive cellular towers. It also decreases the backhaul costs since it routes your mobile phone traffic through the IP network. [http://www.tatarasystems.com/contentmgr/showdetails.php/id/444 Source]
+A femtocell is sometimes referred to as a “home base station”, “access point base station”, “3G access point”, “small cellular base station” and “personal 2G-3G base station”.
-Update - LTE-Advanced has been granted 4G compliance given the significant improvement they provide over 3G technologies [http://www.itu.int/net/pressoffice/press_releases/2010/48.aspx]

-Voice traffic will be supported mainly as Voice over IP (VoIP) enabling better integration with other multimedia services.LTE is being designed to be a high data rate and low latency system. LTE is also aimed at minimizing cost and power consumption while ensuring backward-compatibility and a cost effective migration from UMTS systems.

-LTE is expected to support different types of services including web browsing, FTP, video streaming, VoIP, online gaming, real time video, push-to-talk and push-to-view. Therefore, it is being designed to be a high data rate and low latency system as indicated by the key performance criteria shown below.

-===LTE frame structure===
-In order to maintain synchronization and manage different types of information exchange that need to be carried between the base-station or eNodeB and the User Equipment (UE),  LTE system has a defined LTE frame and sub frame structure for the E-UTRA or Evolved UMTS Terrestrial Radio Access
-There are two types of LTE frame structure:
-* '''Type 1:used for the LTE FDD mode systems'''
-** The basic type 1 LTE frame has an overall length of 10 ms. This is then divided into a total of 20 individual slots. LTE sub frames then consist of two slots - in other words there are ten LTE sub frames within a frame.
-[[Image:type1f.jpg|thumb|centre|600px|[http://www.radio-electronics.com/info/cellulartelecomms/lte-long-term-evolution/lte-frame-subframe-structure.php LTE frame structure]]]
-* '''Type 2:used for the LTE TDD systems'''
-** The frame structure for the type 2 frames used on LTE TDD is somewhat different. The 10 ms frame comprises two half frames, each 5 ms long. The LTE half-frames are further split into five sub frames, each 1ms long.
-[[Image:type2f.jpg|thumb|centre|600px|[http://www.radio-electronics.com/info/cellulartelecomms/lte-long-term-evolution/lte-frame-subframe-structure.php LTE frame structure]]]
-* The subframes may be divided into standard sub frames of special sub frames. The special sub frames consist of three fields
-** DwPTS - Downlink Pilot Time Slot
-** GP - Guard Period
-** UpPTS - Uplink Pilot Time Slot.
-==LTE enabling technologies==
-* '''OFDMA (Orthogonal Frequency Division Multiple Access)'''
-** It is used in the downlink communication of LTE as it can support high data rates
-* '''SC-FDMA (Single Carrier FDMA)'''
-** It is used in the uplink communication of LTE as it helps in reducing terminal power consumption
-* '''MIMO (Multi-Input Multi-Output)'''
-** Helps in obtaining increased data rates with usage of many antennas.
-* '''System Architecture Evolution(SAE)'''
-** New core network architecture to support the high-throughput / low latency LTE access system
-** Simplified network architecture
-** All IP network
-** All services are via PS domain only, No CS domain
-** Support mobility between multiple heterogeneous access system
-* '''Fractional frequency reuse'''
-** Helps in reusing the frequency so that spectral efficiency can be improved

-==MIMO(Multiple Input Multiple Output)==
-Multiple input multiple output (MIMO) technologies introduced in LTE such as spatial multiplexing, transmit diversity, and beamforming are key components for providing higher peak rate at a better system efficiency, which are essential for supporting future broadband data service over wireless links.In Long Term Evolution (LTE), MIMO technologies have been widely used to improve downlink peak rate, cell coverage, as well as average cell throughput.
-To achieve this diverse set of objectives, LTE adopted various MIMO technologies including transmit diversity, single user (SU)-MIMO, multiuser (MU)-MIMO, closed-loop rank-1 precoding, and dedicated beamforming. [http://www.hindawi.com/journals/wcn/2009/302092.html MIMO in LTE]

In one method, at least one data symbol stream is received for transmission from a plurality of antennas. Each data symbol stream is scaled with a respective weight corresponding to the amount of transmit power allocated to that stream. The scaled data symbol stream(s) are multiplied with a transmit basis matrix to provide a plurality of transmit symbol streams for the plurality of antennas. The transmit basis matrix (e.g., a Walsh-Hadamard matrix or a DFT matrix) is defined such that each data symbol stream is transmitted from all antennas and each transmit symbol stream is transmitted at (or near) the full power for the associated antenna.

The encoded pilot symbols are then inserted into an OFDM frame to form a diamond lattice, the diamond lattices for the different transmitting antennae using the same frequencies but being offset from each other by a single symbol in the time domain. At the OFDM receiver, a channel response is estimated for a symbol central to each diamond of the diamond lattice using a two-dimensional interpolation. The estimated channel responses are smoothed in the frequency domain. The channel responses of remaining symbols are then estimated by interpolation in the frequency domain.

-|System access and synchronization methods for MIMO OFDM communications systems and physical layer packet and preamble design
+|Claims, Title or Abstract
-|A method and apparatus are provided for performing acquisition, synchronization and cell selection within an MIMO-OFDM communication system. A coarse synchronization is performed to determine a searching window. A fine synchronization is then performed by measuring correlations between subsets of signal samples, whose first signal sample lies within the searching window, and known values. The correlations are performed in the frequency domain of the received signal. In a multiple-output OFDM system, each antenna of the OFDM transmitter has a unique known value. The known value is transmitted as pairs of consecutive pilot symbols, each pair of pilot symbols being transmitted at the same subset of sub-carrier frequencies within the OFDM frame.

+|Call admission priority control determination device and mobile wireless communication system
+|When more than one terminal is present in the same cell and these terminals communicate with one base station, the wireless resources of that base station are shared among the plural terminals. As a result, the communication rate becomes lower than when communication is performed by only one terminal. Thus, there is a problem that the use of the femtocell base station by other users deteriorates the quality of communication by specified terminal users such as the femtocell base station administrator.
+|It can be solved by a call admission priority control determination device including a registration table containing base station ID numbers of base stations and an ID number of a high-priority first terminal, and a call admission determination unit that determines call admission with reference to the registration table, wherein, when a connection request or a switching-over request for a third terminal has been received from a base station control device, the call admission determination unit, on the basis of this request, references the registration table and determines whether or not call admission for the third terminal is to be permitted.
