# Any combination of mobile and fixed access, voice, video and data services
decrease operational costs by using common resources - transport, OA&M
# FMC implementation leads to a new market with unique list of services and
high revenue potential
Fixed-Mobile Convergence allows network and service operators to make more
efficient use of existing access technologies (GSM, DSL, Wi-Fi), as well as
taking an advantage of the roll-out of new access technologies such as 2.5/3G,
WLAN, Bluetooth, Wi-Max UMA, etc, by launching new voice & multimedia
services and realizing cost reductions by implementing common service
machinery for different access networks.
Users can be contacted with a single number independent of the network connection. The target of convergence is to enable easy implementation for the operator and service provider, and easy usage of services for end users. This will enable true mobility for users in both the residential and business environment.
# According ITU a number of global wireless phone subscribers exceeded the number
of wireline subscribers in 2002
# In 2005 worldwide projections are for about 1.2 billion wireline subscribers and
almost 2 billion wireless subscribers
# Wireline subscribers’ annual growth estimated at 2% and wireless growth at 10%
# While mobile phone operators have seen phenomenal growth in their market,
competition has eroded their average revenue per user

The following definition of FMC is based on the ETSI FMC ad hoc workgroup docs:
Fixed and Mobile Convergence (FMC) is concerned with the provision of network and service capabilities, which are independent of the access technique. This does not necessarily imply the physical convergence of networks. It is concerned with the development of converged network capabilities and supporting standards. This set of standards may be used to offer a set of consistent services via fixed or mobile access to fixed or mobile, public or private networks.
An important feature of FMC is to allow users to access a consistent set of services from any fixed or mobile terminal via any compatible access point. An important extension of this principle is related to roaming: users should be able to roam between different networks and be able to use the same consistent set of services through those visited networks. This feature is referred to as the Virtual Home Environment (VHE).
Operator motivations – better position on the market –increasing revenue, gaining new users
UMTS characteristics in relation to FMC
The following UMTS characteristics can be identified as potential
enablers for FMC:
A. UMTS service capabilities
B. UMTS radio interface applicability to a wide range of application
C. FMC application scenarios in relation to UMTS
UMTS terrestrial radio interface (UTRA)
The UMTS terrestrial radio interface UTRA provides the W-CDMA mode and the TD-CDMA mode
The W-CDMA mode - for public macro- and micro-cell environments and paired spectrum allocations and for data rates up to 2 Mbit/s
The TD-CDMA mode - for public micro- and pico-cell environments, for unlicensed cordless and public wireless local loops, unpaired spectrum allocations and for data rates up to 2 Mbit/s (asymmetric traffic)
The "Personal Number Service" means that the customer is available round the clock at a single personal phone number, regardless of whether located in a fixed or a mobile network. User-specific profiles managed by the user define whose calls shall get through, when and where. Also, incoming calls can be diverted to a single mailbox.
Fixed Mobile Convergence and Virtual Private Network (FMC-VPN)
The VPN under FMC conditions offers a series of improved performance features for fixed and mobile networks in form of an extended version of classic VPN service (= defined user group with access to the short numbers for the individual members and special rates). For example, the same short number can be used both on the mobile device and on the device connected at the fixed connection. Separate billing of private and business calls makes the invoice easy to read for the company and their staff. This service is suitable when combined with individual rate systems — especially for companies with various locations, fixed and mobile personnel and temporary staff.
This service allows the end-user to define several telephone numbers that enjoy lower rates. The F&F list may contain the numbers of business partners, family members or friends who are called frequently, whereby special rates are valid for both the fixed and the mobile network. The end-user can easily administer these preferred numbers via a fixed network telephone, his mobile phone or the Internet.
Prepaid Service (PPS)
PPS was created for those customers who would rather not bind themselves by long-term contracts to any one fixed or mobile network operator, but who also do not want to lose the added value of integrated fixed and mobile networks. This service allows customers to communicate via fixed terminals or mobile phones and they will be charged to one single account paid in advance. The account balance is constantly kept up-to-date. The customer has clear control of his communications expenses through checking his account balance and through the various ways of renewing the account by individually defined amounts of money.
IP Multimedia Subsystem (IMS) is a new framework, basically specified for
mobile networks, for providing Internet Protocol (IP) telecommunications
It has been introduced by the Third Generation Partnership Project (3GPP) in
two phases (release 5 and release 6) for Universal Mobile Telecommunications
System (UMTS) networks. An IP multimedia framework was later introduced
by 3GPP2 as the MultiMedia Domain (MMD) for third generation Code Division
Multiple Access 2000 (CDMA2000) networks.
The IP Multimedia Subsystemis an open, standardized, NGN multi-media
architecture for mobile and fixed IP-based services. It's a VoIP
implementation based on a 3GPP variant of SIP, and runs over the
standard Internet protocol. It's used by Telcos in NGN networks (which
combine voice and data in a single packet switched network), to offer network
controlled multimedia services.
The aim of IMS is not only to provide new services but to provide all the
services, current and future, that the Internet provides. In addition, users
have to be able to execute all their services when roaming as well as
from their home networks. To achieve these goals the IMS uses open
standard IP protocols, defined by the IETF.
So, a multi-media session between 2 IMS users,
between an IMS user and a user on the Internet,
and between 2 users on the Internet is established
using exactly the same protocol. Moreover, the
interfaces for service developers are also based in
IP protocols. This is why the IMS truly merges the
Internet with the cellular world; it uses cellular
technologies to provide ubiquitous access and
Internet technologies to provide appealing services.
The IMS concept was introduced to address the following network and user
• Deliver person-to-person real-time IP-based multimedia communications
(e.g. voice or video telephony) as well as person-to-machine communications
(e.g. gaming service).
• Fully integrate real-time with non-real-time multimedia communications
(e.g. live streaming and chat).
of presence and instant messaging).
• Easy user setup of multiple services in a single session or multiple
simultaneous synchronized sessions.
TISPAN - Telecoms & Internet converged Services & Protocols for Advanced Networks
Release 1999 (R’99) in April 1999 - the initial standards for UMTS were
completed by 3GPP. These standards are the basis for a majority of the
current commercially deployed UMTS systems
Release 4 (Rel’4) in April 2001 was standardized in 3GPP, which provided
some improvements of the UMTS transport, radio interface and architecture.
Rel’5 of UMTS was completed in March 2002 - next significant evolution phase
of UMTS. UMTS Rel’5 will provide higher speed wireless data services with
vastly improved spectral efficiencies through the High Speed Downlink Packet
Access (HSDPA) feature.
High Speed Downlink Packet Access (HSDPA) offers significantly higher
data capacity and data user speeds on the downlink (theoretically up to 14
Mbps peak) compared to R’99 UMTS through the use of very dynamic adaptive
modulation, coding and scheduling with Hybrid Automatic Retransmission
Request (H-ARQ) processing.
Through HSDPA, operators will benefit from a technology that will provide
improved end-user experience for Web access, file download and streaming
Services,Wireless Broadband access to the Internet, intranet and corporate
LAN will benefit greatly from HSDPA.
In addition to HSDPA, UMTS Rel’5 introduces the IP Multimedia System
(IMS) architecture that promises to greatly enhance the end-user experience
for Integrated multimedia applications and offer the mobile operator an
efficient means for offering such services.
The IMS enables new and more advanced multimedia applications for
operators (including VoIP), the ability for these services to interact and the
ability to fully integrate real-time, near real-time as well as non-real time
UMTS Rel’5 also introduces the IP UTRAN concept to realize network
efficiencies and reduce network costs. IP UTRAN uses IP as a transport
protocol to realize network efficiencies that reduce the cost of delivering
traffic and can provide wireless traffic routing flexibility.
