Why do we need QoS?UMTS networks support services with very different performance requirementsReal-time services require performance guaranteesCustomer acceptance closely tied to service qualityOptimal usage of network resourcesRadio resources scarceCost-effectivenessReturn of investmentService and user differentiationMeet different needs of customers (e.g. business vs. consumer)Support different services (real-time vs. best effort)Competitive advantage!

QoS for different services

UMTS BEARERS

The Attributes (QoS Parameters) of a Bearer Service can be negotiated at the beginning of connection and during a connection Several different Bearer Services can be established simultaneously by one UE

Important Quality Parameters areMaximum transfer delay Delay variation Bit error ratioData rate

A bearer is a logical connection between two end points with specificservice capabilities

A bearer service includes all aspects to enable the provision of acontracted QoS (e.g., controlling, signalling, user plane transport,management functionalities).QoS support in UMTS is based on the concept of bearer service

***How Wireless technology evolves?1G- the beginning/birth of commercial mobile network. Since then, there has been tremendous effort in developing mobile network equipment to further enhance the performance of the system.

1G: Purpose to enable wireless communication. (FDMA) Voice quality & capacity limitation. NMT,TACS-systems for analogue wireless phone2G: Aim for wireless high quality voice service. High quality, that is compatible with fixed line quality.3G: Provide for high quality multimedia service. Subscribers demand, operator needs for new source of revenue.Data service were available for wired connection, thus crippled the mobility of mobile device like laptop.NMT : Nordic Mobile Telephone, the first international standardization group (Denmark, Finland, Iceland, Norway & Sweden).TACS : Total Access Communication System (Europe & China)AMPS : Advanced Mobile Phone Systems (USA)TDMA (D-AMPS) digital advanced mobile phone system.PDC: Personal Digital Cellular (Japan)GPRS: General Packet Radio Service. - Hardware (eg BTS: PCU, GPRS)EDGE : Enhance data rate for global evolution.-Provide higher data rates than GPRS. Can co-exist with GPRS. When used with GPRS, its called EGPRS.-New transcoder in BTS and software upgrade in both BTS and BSC.Before: Voice, SMS, E-mail3G: Voice, Video, SMS, WAP, Email, Web, MMS, StreamingNeed reliable and high speed access to email, data & application.Provide LAN like connectivity on the road, enable user to work as if they never leave the office, thus enhance productivity.

In the past 20 years, there have been tremendous effort being put in, to provide better services. Now, this bring us to a question, as to what are the driving factors that influence/shape the development/future of mobile communication?

*The UMTS system has been designed in order to provide a full system, which can either transport voice or data, with rates going up to 2 Mbit/s, and is able to provide Quality of Service in terms of delays, jitter, errors So it is not an overlay, like GPRS for GSM.The Access Network is totally new, using the WCDMA transmission technology.The Core Network uses a packet backbone as a transportation network.Anyway, many of the UMTS operators are the present GSM/GPRS operators.This is why, in order to ensure a smooth transition, there is convergence towards a packet backbone Core Network, by reusing the CS and PS parts already in place in the GSM/GPRS networks.

ServicesIn GSM (and GPRS) most of the services are directly related to the core network software and hardware elements. This means that it is very difficult to develop a new service quickly, and one which is operator specific. In order to be as independent as possible, IN (Intelligent Networks) are taking a bigger importance, but they still rely on a core network that needs to evolve with them.The advantage of the UMTS Core Network is to propose a structure that provides new interfaces and protocols in order to transport services, without being tied to their development.*This slide shows potential prototypes for 3G UE (User Equipment).1) WAP browsing with color displayclear and color displaydownloading and playing of musichi-fi built-in music playerdownloading and storing music/storage data card

3) Direct connection to PC/Personal Digital Assistanthigh speed data communication*3GPP includes five organizational partners: ARIB and TTC from JapanT1 from USATTA from KoreaETSI from Europe (based in France)These five organizations have the capability and authority to define, publish and set standards within the 3GPP scope in their respective areas.3GPP also includes Market Representation partners who are by order of admission: UMTS forum (UK based)GSA (Global Mobile Suppliers Association, UK-based)GSM Association (Ireland-based)CWTS (China Wireless Telecommunication Standard group)IPv6 forum (Luxemburg-based)A Market Representation partner is invited by the organizational partners to offer advice to 3GPP and bring a consensus view of market requirements. It does not have the capability and authority to define, publish and set standards within the 3GPP scope, nationally or regionally.Nortel Networks is also deeply involved with teams working on definition of specifications.

3GPP2 is the equivalent of 3GPP for CDMA 2000.IMT-2000 (International Mobile Telecommunications-2000) is the global standard for third generation (3G) wireless communications as defined by the International Telecommunication Union.

TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) is a 3G mobile telecommunications standard, being pursued in the People's Republic of China by the Chinese Academy of Telecommunications Technology (CATT), Datang and Siemens AG *******RAB Radio Access BearerSween J Ambat2006-09-07**
