Mobile Wireless Internet Forum (MWIF)

2

Mission Statement

Drive an Open Internet-based architecture that:

enables seamless integration of mobile telephony and IP-based Services (voice, data, video, web, etc.) for

the mobile wireless networks

and

is independent of the Air Interface

3

Problem Statement

• Cost of wireless infrastructure– Not aligned with IP infrastructure and its cost curves

– Lack of support for fast creation / deployment of innovative services (Time to Market)

• Standards delaying Wireless Internet adoption – No singular, unified approach across standard bodies / access

technologies– Limited alignment with Internet & related services– Reduced operator / service provider revenues due to delay in Wireless

Internet adoption

• Current proposed architectures do not:– allow services to be globally seamless– enable services that are rich enough or sufficiently varied for end users– allow operators / service providers to create & deploy services quickly

and independently

The Mobile Wireless Internet Forum will:

- be Open to all operators, service providers and suppliers who have a desire to produce a global, common vision for an Internet-based mobile wireless network and related service capabilities

- Act as a driver that is complementary to the existing standards working groups and will provide a common voice of global operators

- Ensure that key regional and global standards groups address requirements that global operators see critical to early and economic deployment of IP-based mobile wireless network

- will be mobile technology neutral and not biased towards any particular standards

Network Architecture Goals• Harmonization across access technologies by promoting common IP

Core architecture – Extends from Wireline, DSL, Cable, etc. to Wireless (Fixed & Mobile)

• Independent of radio technology – Open all pertinent Interfaces* (including RAN internal interfaces)– IP (Packet) from BTS/Node-B (possibly VoIP from handset)– Extend multi-vendor IP transport to the BTS

• Common operation of services and applications – Regardless of access technology (or air interface - both 2G and 3G)– Independent of home / roaming network

• Distributed, peer-to-peer architecture for scalability– Intelligence distributed in the network and end points– Separation of bearer and signaling reduces network congestion– IP standard interfaces to Billing & Customer Care

* those that are of interest to the operators & service providers (for supplier choice and flexibility)

7

Network Architecture Goals cont...

• Global alignment – Minimize impact of regional/country differences in key interfaces– Globally accessible services– Interoperability with 2G & 3G Networks– Unified architecture across technologies (GSM, CDMA, etc.)– Inter-technology Mobility Management (separate Mobility Management function)

• Performance, Quality, Reliability– End-to-end QoS mechanism– QoS mechanisms for wireless and wireline convergence

8

MWIF & Current Standards Groups• The Mobile Wireless Internet Forum will highlight and

address gaps in current standards work and Enable operators to create momentum:

– by accelerating work on key IP-based standards that will enable early implementation of IP Mobile Wireless network (submit contributions to appropriate standards bodies)

– by reviewing 3GPP, 3GPP2 and ITU work, and where appropriate provide contributions that are targeted at acceleration and alignment of standards activities (including 2G)

– by creating liaison functions between MWIF and all key standards working groups and forums (including IETF/ITU, T1P1, CDG, 3GPP, 3GPP2, GSM Association, UMTS Forum, JIMM, etc.) to communicate the common voice of the global set of operators

MWIF Deliverables

• Expected Deliverables– Finalized Reference Architecture - Feb/Mar 2000– Finalized Interface / Functional definitions - 2Q, 2000– Submissions to Standards Bodies to begin 1Q/2Q, 2000*

Deliverables will Address:– Architecture gap analysis with respect to other standards’ work– Extension of IP to BTS - Maximize number of IP based elements and

interfaces– Inter-technology mobility management

* MWIF will keep the different standards bodies’ target dates in mind for submissions
