Definisi

ITU-T Rec Q.1762/Y.2802 (Fixed-mobile Convergence General
Requirements)
–
–
In a given network configuration, the capabilities that provide same services and
application to the end user regardless of the fixed or mobile access technologies being
used and independent of the user’s location.
In the NGN environment, it means to provide NGN services to end users regardless of
the fixed or mobile access technologies being used.

FMC secara umum adalah konvergensi antara fixed dan mobile network yang
memungkinkan user mengakses tiga layanan utama, yaitu:
– layanan voice yang menjadi andalan fixed network,
– mobility dan kekayaan layanan yang dimiliki mobile network, serta
– internet-based application (transfer informasi dan transaksi)

Konvergensi ini akan berujung kepada layanan multimedia, dengan dukungan
bandwidth yang memadai dan mobilitas tinggi.

Mengapa FMC ?
 In Fixed Operator (with no Mobile assets) perspective,
–
FMC could reverse the loss of voice-service minutes and revenue to mobile
providers (MNVOs), reduce CAPEX and OPEX (harmonized network), offer
new value-added services, reduce churn rate, attract new customers, and
as market “Brand”
 In Fixed Operator (with Mobile assets) perspective,
–
FMC could reduce CAPEX and OPEX (harmonized network) and offer new
value-added services / increase revenue
 In Mobile Operator perspective,
–
FMC could reduce CAPEX and OPEX (harmonised network), offer new valueadded services and improve coverage (indoor /outdoor – WiFi)

Model FMC di Telco
 Service Bundling/Commercial Convergence
–
–
fixed & mobile services are bundled together with a single bill
operator dapat memberikan bundling harga bagi pelanggan produk fixed
dan mobile melalui pengembangan aplikasi billing yang memadukan billing
fixed dan mobile ke dalam satu paket, sementara layanan dan jaringannya
sendiri masih terpisah.
 Device Convergence
–
–
Dengan satu terminal pelanggan dapat melakukan panggilan baik melalui
jaringan fixed maupun mobile
Contoh: UMA / GAN, Femtocell
 Network Convergence
–
–
Jaringan operator telah convergence dengan menggunakan all-IP network.
Menggunakan IMS sebagai node untuk mengontrol baik fixed maupun
mobile network

Karakteristik Teknis FMC
 Seamless service operation: FMC harus menjamin bahwa user
dapat mengakses layanan FMC dari semua jaringan, baik fixed
maupun mobile network.
 Seamless services provisioning: FMC harus menjamin bahwa
operator dapat menyediakan layanan FMC di semua jaringan,
baik fixed maupun mobile network.
 Support to mobility: user mobility dan session mobility.
 Ubiquity of service availability: user dapat menikmati semua
layanan/aplikasi (any service) dari manapun (any location)
dengan menggunakan terminal apapun (any device).

CTP and UMA
• Cordless Telephony Profile (CTP) and
Unlicensed Mobile Access ( UMA) are, very
loosely, two alternative short-range wireless
standards that enable fixed-mobile convergence
(FMC) solutions.
• Most players in the FMC space see UMA as the
longer-term technology than CTP.
• However, CTP is being deployed by some
manufacturers, and some operators, as an
interim solution, because CTP equipment can be
attached to existing networks without any
changes.

CTP (Cordless Telephony Profile)
•
•
•
•
CTP is a profile defined within the Bluetooth specification, by the Bluetooth
Special Interest Group, which allows a Bluetooth-enabled mobile phone to
be used as a cordless telephone when it is within range of a Bluetooth CTP
access point. CTP is thus a way of adding limited mobility - cordlessness to the fixed network.
CTP acts as an application on the device - which is sometimes a mobile
phone and sometimes a hands-free / wireless headset. The simplest
implementations simply use Bluetooth as a local air
interface comparable to DECT. Here, the access point plugs directly into an
analogue telephone line. Bluetooth Class 1 chips that allow communications
over ranges 'up to' 100m are beginning to become available and to be
included in mobile devices. This is still not as good as DECT range, but
CTP has the advantage of being present in mobile devices and having
access to their address books and presentation capabilities.
Mobile and fixed access are only loosely converged in CTP. The mobile
device retains its GSM number, whereas the CTP access point uses the
number associated with the fixed line to which it is attached.

UMA (Unlicensed Mobile Access)
•
•
•
•
•
In its earliest implementation, UMA is also a way of using Bluetooth to
provide limited mobility, using a cordless link and an access point
connected to the fixed network.
Although it is superficially similar, UMA is actually very different from CTP.
For a start, while CTP is limited to the Bluetooth air interface technology,
UMA is an 'air interface agnostic' specification, which can be used in
conjunction with Bluetooth, WiFi or even as yet undefined access
technologies.
The specification has been developed by a group of manufacturers
Same mobile number can be accessed via the existing BTS or Wi-Fi
The UMA solution has become a 3GPP standard named GAN (Generic
Access Network)

UMA (Unlicensed Universal Mobile Access)
The use of this UMA architecture applies also to the licensed band. In recognition
of this, UMA is starting to be redefined as “universal” mobile access.

Solusi Femtocell
•
•
•
•
•
Merupakan suatu Base Station selular yang didesain untuk digunakan di dalam rumah atau suatu
kawasan small business
Menggunakan jaringan broadband (DSL) untuk menghubungkan dirinya dengan jaringan operator
seluler.
Umumnya dapat melayani 2 – 5 pengguna dalam kawasan rumah tersebut
Femtocell memungkinkan operator seluler untuk memperpanjang cakupannya ke dalam rumah,
khususnya di mana akses jaringannya terbatas, tanpa harus membangun menara BTS yang mahal.
Femtocell juga mengefisienkan biaya backhaul karena menggunakan jaringan IP untuk menyalurkan
trafiknya.
Sering disebut “home base station”, “access point base station”, “3G access point”, “small cellular
base station” dan “personal 2G-3G base station

IP Multimedia Subsystem (IMS)
• IP Multimedia Subsystem (IMS) is a SIP based
standardized architecture for offering multimedia
services on the packet domain
• Originally defined by mobile (3GPP/3GPP2) standards
– IMS is defined by 3GPP from Release 5 onwards (2002) *)
– 3GPP2 equivalent of IMS is the MMD (Multi Media Domain), fully
interoperable with 3GPP IMS *)
• Essentially access independent / access agnostic
(service transparency)
– Supports broad, mobile packet data
• Interoperability of new converged services between
subscribers
• Interworking with PSTN and legacy service

Converged Network Scenarios
• UMA/GAN:
– Offers a pragmatic solution for mobile operators with an embedded CS
network to extend their coverage using WLAN.
– However, it does not provide an evolution path to an all-IP NGN, since it
keeps voice calls in the CS domain.
• IMS-based:
– Circuit Switched and IMS services (CSI):
•
•
•
Allows IMS services to be extended to a terminal on a GAN access.
This is a rather circuitous way to provide IMS services to a fixed access compared to the fixed network
architecture.
The latter is therefore recommended by Q.FMC-IMS as an evolution path for the fixed access part of a
WLAN/2G fixed mobile convergence solution, in combination with the VCC architecture described below.
– Voice Call Continuity (VCC):
•
•
•
Seamless service over fixed and mobile network with one phone number
An alternative – centric - approach to provide service continuity for voice calls when a multi-mode WLANSIP/2G-3G-CS terminal changes its point of attachment.
VCC provides the capability to transfer the path of a voice call between a CS and a PS-IMS domain. It assumes
that the UE is capable of supporting two separate call legs related to the same voice communications (one over
the CS domain and theother via the IMS). The approach for the first set of VCC specifications (part of 3GPP
release 7) is static anchoring of all voice calls in the IMS of the user’s home network.
