LTE(長期演進)定義了未來4G無線通信標準，提供基於IP的服務，並能保證服務質量(QoS)及無縫移動。除了為UE和eNodeB定義的空中接口外，3GPP在規範中還定義了接入網的架構。 LTE還提出了高數據吞吐率和用戶容量的要求（例如，每個基站可提供100Mbps和支持數百個用戶）。可以預計每個用戶所佔用的數據帶寬增加的同時，服務計劃將能提供更低的每MB收費甚至為高用量用戶提供包月收費。 現有的用於部署3G/HSPA數據業務的網絡架構有很多問題，無法遷移到LTE: • 包含很多網元的複雜架構，帶來很高的網絡成本和網絡延時； • 有限的吞吐率； • 擴展成本高。 因此，3GPP標準提出了演進分組系統(EPS)，包含了LTE的演進接入網架構。 LTE技術的發展給中型技術公司帶來了很多機會。不少中型公司已經有了LTE基站(eNodeB)的開發計劃, 與其 LTE的基地台宏（稱為 eNodeB的），他們可以發展為規模較小的基站，微微蜂窩 / femotcell解決利基市場。然而對他們來說，要贏得競爭並且賣給第二層LTE網絡運營商，必須提供低成本且完整的演進分組系統，包括eNodeB，接入網網元和網絡管理系統。中型公司有很多優勢，如成本優勢，在市場上有很大的潛力。 該項目旨在幫助這些中等規模公司，通過提供本項目開發產品的許可證，讓他們可以快速開發出他們自己的LTE EPS解決方案。本項目成果將包括具成本效益的可擴展的控制平面，數據平面和管理平面的LTE接入網設備軟件的。這將大大降低購買許可者的研發成本、研發風險和銷售的資本支出。 項目團隊從CWMS和WiMAX ASN-GW項目積累而來的經驗、知識和框架為項目提供了堅實的基礎。同時，已經獲得了WiMAX ASN-GW的許可證的一家香港上市公司，正在與項目團隊密切磋商購買所開發技術的許可證。
