FMC Today Focus on Voice (VCC) and SMS - now Messaging Symbian S60 and UIQ CDMA / BREW (Kyocera Wi-Fi) Windows Mobile (InROM ISV) • Bandwidth and network are limiting factors • Handsets have been an issue • Wi-Fi used in place of 3G • Applications are bandwidth and handset limited Mobility and Bandwidth are driving forces for FMC
Fixed Mobile Convergence • Way of connecting wireless to wireline infrastructure • The ultimate goal of convergence is to deliver seamless experience across multiple locations, multiple devices and multiple types of use (The Yankee group, Nov 2004)
Multi N/w Deployment (Reference:http://www.baypackets.com/fixed_mobile_convergence.html) Features of FMC
Features of FMC • Unified Service of fixed and mobile n/w’s with one phone, one number and one bill • Seamless roaming between cellular, Wi-Fi, WiMAX and what ever wireless technology comes next. • More reliable mobile service with wider coverage at lower cost. Closer integration between public and enterprise phone networks. • Friendly user interfaces that makes it easy to make and manage calls (the user has a choice to select the type of network depending upon cost and convenience).
Features of FMC • Friendly user interface that makes it easy to make and manage calls (the user has a choice of N/w depending upon chose and convenience).
Motivator FMC • Fixed Operator (with no Mobile assets) Perspective • 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, attract new customers, market “Brand” • Fixed Operator (with Mobile assets) Perspective • Reduce CAPEX and OPEX (harmonized network) • Offer new value-added Services -increase revenue • Mobile Operator Perspective • Reduce CAPEX and OPEX (harmonized network) • Offer new value-added Services` • Improve coverage (indoor /outdoor –Wi-Fi) • Cable Operator Perspective • Can offer a quadruple bundling of VoIP, video, mobility and broadband access services • Source: • Adrian Scrase (ETSI), Mobile Fixed Convergence Progress with the Joint 3GPP and ETSI TISPAN Initiative, 3G World Congress, November 2005 • Girish, Muckai (ARRIS), “Fixed Mobile Convergence for Cable Operators”, June 2006
Objective FMC • Seamless services from the user perspective across the heterogeneousfixed (i.e., PSTN, ISDN, PSDN, WAN/LAN/CATV, etc) and mobile networks should be guaranteed in FMC. • Seamless service provisioning from the operator perspective across the heterogeneous fixed (i.e., PSTN, ISDN, PSDN, WAN/LAN/CATV, etc) and mobile networks should be guaranteed in FMC. • Generalized Mobility supporting should be supported in FMC (i.e., terminal mobility, user mobility and session mobility). For a given scenario, different level mobility may be needed. • Ubiquity of service availability. The end-users can enjoy virtually any application, from any location, on any device. All the services/application can be used by an end-user through any kind of access technology if that service has been subscribed and is supported by his/her terminal device. The service/application availability is only dependent on the user's subscription and capability of the terminals. • Supporting multiple user identities and authentication/authorization mechanisms.

So why don’t I give all my employees a mobile phone and be done with it? • Cost - mobile minutes are more expensive than landline minutes • Stranded Assets – I’ve invested in IP PBXs and IP desk phones and do not want those investments to go to waste • Lack of Integration - My deskbound employees don’t need a mobile phone, but I don’t want two islands of users (desk and mobile) Fixed Mobile Convergence – the seamless integration of mobility into business’s fixed infrastructure - addresses each of these concerns
FMC addresses “going mobile” • Cost - mobile minutes are more expensive than landline minutes • Stranded Assets – I’ve invested in IP PBXs and IP desk phones and do not want those investments to go to waste • Lack of Integration - My deskbound employees don’t need a mobile phone, but I don’t want two islands of users A key component of FMC is cost efficiency – many implementations can keep calls “on-net”, saving mobile minutes FMC is designed to work in tandem with existing infrastructure, in many cases making it more useful The beauty of FMC is that deskbound, semi-mobile, and mobile employees share the same feature capability and environment
Levels of FMC • Network Convergence: Fixed/mobile networks physically share transportation infrastructure. (access N/w & core N/w) • Commercial Convergence: Resources of Fixed/mobile networks are pooled. • Service Convergence: Seamless delivery of Fixed/mobile telephony and supporting services is achieved. (voice, IM, SMS) • Terminal Convergence:
FMC + Access Technologies: • Digital subscriber line (DSL): 24 Mbps downstream 3 Mbps upstream. converged multimedia applications • Wireless local area network (WLAN): low-cost, high-bandwidth A user with WLAN access could be connected through appropriate multi-access (WLAN and cellular) terminals to the Internet, to the PSTN, or to mobile network(s).
FMC + Access Technologies • Wireless Interoperability for Microwave Access (WiMAX) : Broadband wireless access (BWA). 2 - 11 GHz frequency band range (as per IEEE specification in 2004). • Unlicensed Mobile Access (UMA):roaming between a cellular network and fixed IP-based wireless networks.
FMC in Some Places Include • Multi Media Messaging Service (MMS) • WLAN with CDMA service • Integrated Portal Service
Multi Media Messaging Service (MMS) • MMS allows mobile phone users send and receive messages with formatted text graphics, photographs and audio –video clips. • With the integration of digital camera and mobile phone, MMS usage increases.
WLAN with CDMA • In a zone where an access point is established, subscribes use WLAN service. When the subscribers are out of zone, they use CDMA. • High speed, low price from WLAN • Wide coverage from CDMA
Integrated Portal Service • Integration of mobile and Web-based portals. • It provides aggregated content and services through a mobile Internet network.
Current Typical Solutions for FMC • IP-PBX or soft-switch with mobile n/w interface • IMS based coverage solution • UMA Dual Mode solution
What is IP-PBX??? • The Internet Protocol Private Branch eXchange (IP PBX) is telephone switching equipment that resides in a private business instead of the telephone company. • An IP PBX delivers employees dial-tone, the ability to conference, transfer, and dial other employees by extension number as well as many other features. (Virtual Private Network Services..) • Voice transmissions are sent via data packets over a data network instead of the traditional phone network • Least Routing of cellular. • 3G ???(not applicable to 3G)…

IP Enabled PBX functions on one device while on campus utilizing the WLA|N (802.11 b/g) infrastructure. Reduces on-campus and inter-campus calls. Only with in campus 3G????(not applicable because IP-PBX does not support) (companies like Nokia, Avaya, Motorola use this technology).
FMC using SIP • FMC solutions aimed at wireline operators take an opposite approach from those aimed at wireless providers • Wireline-oriented FMC solutions are based on SIP standards • SIP approach has benefits since SIP has already entered the emerging wireless network (via 3GPP) and is inherently compatible with IMS architecture
INTRODUCTION to SIP • H.323 protocol • Session initiation protocol • SIP considered to be a simpler, more flexible alternative to H.323 with the ability to support advanced services.
What is SIP • SIP or Session Initiation Protocol is an application-level control protocol for setting up, changing and terminating multimedia sessions between participants on IP data networks. • SIP is a text-based protocol, similar to HTTP and SMTP, for initiating interactive communication sessions between users. Such sessions include voice, video, chat, interactive games, and virtual reality.
SIP Entities • User Agent User Agent Client User Agent Server • Proxy Server • Redirect Server • Registrar Server
How SIP works • Long distance calls through the traditional telephony • Telephony system works via a cog and wheel setup • SIP refers to a protocol that allows computers to talk to each other without going through a central station. • SIP is typically offered in two formats, computer based and hardware based
Services that SIP can provide • Call Hold • Consultation Hold • Unattended Transfer • Call forward on Busy/NoAnswer/Unconditiona • 3-Way Conference • Find-Me • Incoming/Outgoing Call Screening • Call Waiting
