3GPP the Partnership

3GPP Stands for 3rd Generation Partnership Project* e ar ners are an ar s eve op ng rgan za ons:

(Japan) (China) (Korea)

(Japan)(USA) (Europe)

Contribution driven companies participate in 3GPP through their membership ofone of these Organizational Partners

Currently over 350 Individual Members (Operators, Vendors, Regulators) 13 Market Representation Partners (giving perspectives on market needs and

drivers)


*3GPPisnotconstrainedto3rd Generation. Itincludesworkonboth2nd and4th generationtechnologies.

Spectrum Issues

LTE Bands:

Re-farmin900/1800MHz GSM bands are attractinga lot of attention, as spectrum re-farming in those bands is seen as one

way to allow the roll out of mobilebroadband services.

Additional spectrum can be added to thespecifications as required.

(eg. 3500MHz currently being added)

Dispelling some Myths about

LTE and IM

Reality: Support of voice was one of the key considerations in designing LTE. The voice solution for

LTE is IMS VoIP and it is fully specified.

y : sn suppor e overReality: LTE and EPS will support a rich variety of messaging applications - including SMS. Thesolution is twofold, covering both the full IMS case and a transition solution for those networks that do

.

Myth 3: IMS isnt ready for prime timeReality: IMS was first developed as part of Rel 5 in 2002. It is based on IETF protocols such as SIP

.signalling mechanism for multimedia applications.

Myth 4: LTE doesnt support emergency callsReality: VoIP support for emergency calls (incl. location) in Rel 9. A transition solution fall back to3G/2G - has existed since IMS was introduced (Rel 5).
