Arquitetura EPS – LTE

EPS – Evolved Packet System

� EPC – Evolved Packet Core

� MME

� SAE/S-GW

� PDN-GW

� E-UTRAN – Evolved UTRAN

� E-NODEB

� UE

• USIM

• TE

NE

� E-nodeB - Evolved Node B

� RRM

• RRC – Radio Resource Control.

• SIS Info e Cell Selection.

• Alocação de Recursos.

• Controle de Acesso (Admission Control).

• Controle de Mobilidade.

� PDCP

• Compressão do cabeçalho IP.

• Segurança (RRC e UP) � IPSEC Opcional

� Roteamento

• CP para MME

• UP para S-GW

• Classificação de pacotes e QoS (MAC)

� Identificação

• GUTI – Similar ao TMSI (Attach)

• TAI – Similar ao RAI

• ECGI – Identificação global da célula.

� MME – Mobilty Management Entity

� CP – Sinalização NAS

• EMM (Attach, Detach, TAU, Service Request, Alocação de GUTI, Autenticação,

Paging, Security Mode Control)

• ESM (Ativação , Modificação e Desativação de Bearer Context)

� Inter MME Handover

� Interligação rede IMS (HSS e AAA)

� S-GW

� UP – Buffer de Pacotes

� GTP/PMIP

� Roteamento de Pacotes

Interfaces

� Uu – RF (RRC e Datagramada IP)

� S1-MME – Control Plane (S1AP)

� S1-U – User Plane (Datagrama IP)

� X2 – User e/ou Control Plane (X2AP)

Protocolos e Funcionalidades

CP: Control Plane

UP: User P lane

EPS – Bearer

Canais Físicos

o Downlink

� PSS – Primary Syncronization (PL Identity – 3 ).

� SSS – Secondary Syncronization (PL Cell Identity – 168).

� PBCH – Physical Broadcast Channel (MIB).

� PDSCH – Physical Downlink Shared Channel (User Data, SIB).

� PDCCH – Physical Downlink Control Channel (Alocação de Recursos).

� PHICH – Physical (HARQ , ACK e NACK UL Packet).

� PCFICH – Physical Control Format Indicator Channel (Símbolos OFDM no PDCCH).

� DRS – Demoulation Reference Signal (Associado a transmissão do PUSCH e PUCCH).

o Uplink

� PUSCH – Physical Uplink Shared Channel (Control e User Data).

� PUCCH – Physical Uplink Control Channel (UCI, CQI, ACK, NACK do DL).

� PRACH – Physical Random Access Channel (Transmissão de Preambulo).

� SRS – Sound Reference Signal ( Garantia de qualidade no canal utilizado).

SRB

o SRB0 – Estabelecimento de RRC mapeado no CCCH – Canal Comum.

o SRB1 – Transporte de mensagens RRC e NAS de Alta prioridade no DCCH – Canal Dedicado.

o SRB2 – Transporte de mensagens RRC e NAS de Baixa prioridade no DCCH – Canal Dedicado.

Physical Layer – RF – OFDMA e SC-FDMA

Banda Brasil

Portadora e SubPortadoras

Ocupação da Portadora – UE/e-NB

SC-FDMA – Single Carrier FDMA

OFDMA – Ortogonal FDMA
