1 Fixed versus Mobile Turning Convergence into Reality Dieter Schuler, Wouter Franx Lucent Technologies

2 Agenda Fixed Mobile Convergence Service Definition Operator Challenges IP Multimedia Subsystem the Solution Summary

3 What s Fixed Mobile Convergence A converged fixed and mobile service is one that enables the user to access the same set of communication services, regardless of the end terminal they use, the underlying network over which those applications run, or the user s location. Convergence Service includes the Handset Devices FIXED MOBILE CONVERGED SERVICES Wireless SP Combined SP Wireline SP Fixed Phone Mobile (2G 3G) SoftClient IP Phone PDA PC WiFI WIMAX Combined WiFi/GSM/UMTS

4 Enterprise Convergence Needs Mobile Phones as common business tools Some corporate liable phones Many personal cell phones used for business Strategies IT deploy to mitigate against increased cellular cost Choice between cell phone vs. desk phone moving to WiFi One WiFi network for both voice and data Convergence Circuit to packet moving to VoIP Wireline and cellular moving to dual mode cellular phones Key PBX features: Transparency of number Call transfer capability from cell, similar to PBX (transfer call to admin/colleague etc.)

5 Consumer Convergence Needs One Service Provider for wireline and wireless communication needs One bill for all communication needs One device and on the move Personal Phone being used as universal device Family Phone still be re-used Popularity of Mobile Devices Broadband Integration Integration of Data and Voice within the Broadband access Cost Savings

6 MILLIONS Fixed mobile handsets W o r ld w id e B u s in e s s a n d C o n s u m e r C e llu la r / W i- F i H a n d s e t F o r e c a s t C o n s u m e r B u s in e s s S o u r c e : "W ir e le s s I P P h o n e s D r iv e F u tu r e M a r k e ts," I n - S ta t, A u g u s t Cellular/WiFi handsets forecast to grow from 24 thousand in 2005 to 89.1 million by % of dual mode handsets expected to be for consumers by 2009

7 Wireless Operators Wireline displacement Network Operators Challenges Combine offer of wireless service with fixed VoIP service to replace existing POTS service. Improve in-residence coverage. Business Model based on subscription and usage Seeking to displace existing wireline carriers Cable Companies Add wireless service through a partnership/mvno to create a quadruple play service bundle (cable TV, Internet access via cable modem, fixed VoIP, wireless service). Defend and grow new fixed VoIP voice customers. Attacking voice market from a position of strength entertainment Wireline Operators Retain residential subscribers by adding mobility to the offer biggest threat to existing business Provide high value-added, converged services to diferentiate from plain old celular and reduce churn. Business Model based on subscription and usage Converged Operators Leverage advantage in having both wireline and wireless assets and consumer customer relationships. Provide high value-added, converged services to differentiate from competitors. Seeking solutions that stem the erosion Behave predominantly like wireline Disruptive approach IP based VoIP Providers Add wireless service through a partnerships/mvno to augment fixed VoIP service. Compete and differentiate against wireline-only operators. Disruptive service offering over any available broadband access type Business Model mostly not based on subscription and usage

8 Fixed Mobile Convergence Dual Mode Service Leverage broadband access networks as alternate paths to get/make calls Dual Mode Phones can use either outdoor network or indoor WiFi Add WiFi access point/router for indoor mobiles and Internet access DSL or Cable broadband used for backhaul to network Residential VoIP service over broadband Move POTS phones to VoIP adaptor GSM/UMTS IP based Services IP BB Link Macro Cellular Network Single device operates in both domains PSTN X Narrow Band Link Integrate with home service Home WiFi / Broadband Network

9 IP MultiMedia Subsystem Current Vertically Integrated Services IM VoIP Push-to-X IMS Converged Services Arch. USER INTERFACE APPLICATION DB DB DB SESSION Subscriber Data ENDPOINTS IMS Service Architecture Benefits Access Network and End Point agnostic Open application server interfaces to allow a rich set of applications Separate subscriber data for a consistent, maintainable subscriber data Common session control to support service interworking

10 IMS: Next Generation Network Model Converged Applications Layer Session Control and Centralized DB Layer Media Control & Media Gateway Layer Broadband Residential Access Application Servers 802.Xx Access Application Servers Session Control Enterprise Access Circuit Mobile Application Servers Centralized Databases Media Control & Gateways 2G/3G Mobile Network PSTN What is the IP Multi-media Subsystem (IMS)? Industry Standard 3G Partnership Project(s) Standard Interfaces Within and Between Layers Session Management Access to any applications from any access network / device for any media type Centralized Database Identity management Single User sign-on and shared profile for all applications Wireless MSC IMS (IP Multimedia Subsystem) is the blueprint for delivering Value over IP

11 Dual-Mode Roaming & Handoff SS7 HLR Application Server provides Wireless/WiFi roaming and handoff for both consumer and enterprise Dual-Mode Roaming And Handoff DSF/DTF Application Server SIP Session Control (CSCF) MSC MGC IP Network FW (WiFi) SIP Signaling SS7 Signaling TDM Trunking GSM Network SBC SIP Features MG WiFi Dual Mode Handoff Dual Mode Roaming Features (Wireless) Domain Selection Function Application Server contains information whether mobile is in HLR/MSC or in WiFi system Domain Transfer Function Application server hands active calls (bearer) from WiFi to MSC control Supports converged handsets that will be available at end of 2006 Market data suggests that such converged endpoints will dominate the market for consumer and enterprise Works with existing GSM/UMTS networks

12 What is Voice Call Continuity VCCof f er s r eal -time voice call continuity when users move between the GSM/UMTS CS Domain and the IP Connectivity Access Network (e.g., WLAN interworking) with home IMS f unct i onal i t y. VCC Includes: Domain Selection Function for Call Delivery to Dual Mode Handset Domain Transfer Function used for Domain Transfer From IMS/WLAN to GSM/UMTS From GSM/UMTS to IMS/WLAN Services Support Across Domain Transfer (providing services from IMS even when call is being served by CS Domain)

13 Summary Fixed Mobile Convergence Broadband (WiFi) Cellular Dual mode service to start FMC offerings Enhanced communications and enhanced telephony features FMC offer window for wireline and wireless operators Voice convergence is ultimately best served by the IMS infrastructure IMS provides the architectural foundation for dual mode services now and new integrated services in the future Promises lower total cost for service provider in the core network
