Arquitetura, Protocolos, Fluxo de Procedimentos, Configuração E/// e Desempenho VIVO

Mário Márcio Garcia Granja14/01/2013

Arquitetura EPS – LTEEPS – 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 Físicoso 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).

SRBo 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
