System Architecture Evolution (SAE) is the core network architecture of mobile communications protocol group 3GPP's LTE wireless communication standard. SAE is the evolution of the GPRS Core Network, but with a simplified architecture; an all-IP Network (AIPN); support for higher throughput and lower latency radio access networks (RANs); and support for, and mobility between, multiple heterogeneous access networks, including E-UTRA (LTE and LTE Advanced air interface), and 3GPP legacy systems (for example GERAN or UTRAN, air interfaces of GPRS and UMTS respectively), but also non-3GPP systems (for example Wi-Fi, WiMAX or CDMA2000).

  • 시스템 아키텍처 에볼루션(System Architecture Evolution, SAE)는 3GPP EPC망 내에서 호처리 기능을 수행하는 네트워크 구성요소이다. SAE의 대표적인 기능은 다음과 같다. * NAS 관련 메시지 교환 * 페이징(paging), Tracking Area list 관리, 핸드오버와 같은 단말의 이동성 관리 * P-GW, S-GW의 선택 * MME가 바뀌는 핸드오버 시 MME의 선택 * 2G 또는 3G망으로의 핸드오버 시 SGSN의 선택 * 인증 및 인가 (Authentication & Authorization) SAE는 eNB, S-GW, HSS와 같은 네트워크 구성요소와 연동하며, Diameter, S1-AP, GTP등의 프로토콜을 사용한다.

  • System Architecture Evolution (acrônimo SAE) é nomenclatura da rede núcleo do Padrão LTE, as chamadas redes 4G (quarta geração) para redes de comunicações móveis, especificado pelo 3GPP. SAE é a evolução das redes , com certas diferenças evolutivas: * arquitetura simplificada * conceito de redes All-IP (AIPN) * suporte a redes de acesso de altas taxas de velocidade e baixa latência * suporte a mobilidade entre redes de acesso heterogêneas, como e , redes de acesso legadas, como e , bem como redes não-3GPP, como por exemplo WiMAX e cdma2000.
