Authentication & Authorization

AAA ASN-GW WiMAX BS

SS

EAP-TTLS

WiMAX Authentication Architecture LTE Authentication Architecture

UE

HSS MME LTE eNB

AKA

• WiMAX use EAP-TTLS authorization protocol,

the way of username/password, it stored in

AAA and configured information to terminal

• LTE use AKA authorization protocol, the way of

USIM card, it inserted on the terminal, and HSS

save the user’s USIM authentication information

Influence of user: the user habits will be changed, WiMAX user configure username/password in terminal, while LTE

user need to use USIM card.

Influence of operator: the user payment process will be changed, WiMAX need to configure username/password to

customers, while LTE configure USIM.

WiMAX and LTE TDD has different authentication ways.

LTE Qos

• EPS is the basic dimension of LTE network

Qos management & control. A EPS bearer can

transport all SDF(service data flow) with same

Qos.

• EPC bearer has two types, GBR and Non-GBR.

GBR(guarantee bit rate) is a service rate

control parameter, , if the service rate<= GBR,

the service data packet will go through fluently
