4、l5TD Femto端到端組網(wǎng)方案分為三個部分：Femto接入網(wǎng)、SeGW和FEMTO網(wǎng)關(guān)、Femto HLR、HMS驗證及網(wǎng)管系統(tǒng)。HNB安裝、部署在用戶家中，通過寬帶接入到公網(wǎng)（CMNET）和SeGW間建立IPsec Tunnel以保障業(yè)務(wù)安全性及用戶隱私。在IPsec Tunnel建立流程中， Femto HLR對HNB進行EAP-AKA/SIM鑒權(quán)認(rèn)證，認(rèn)證成功后，HNB與SeGW間的IPsec Tunnel才能建立并為HNB分配IuH接口地址，確保HNB和FEMTO網(wǎng)關(guān)信令與業(yè)務(wù)的正常轉(zhuǎn)發(fā)。FEMTO網(wǎng)關(guān)通過IuCS、IuPS接口接入現(xiàn)網(wǎng)核心網(wǎng)，接口協(xié)議棧與RNC完全一致，核心網(wǎng)側(cè)無

5、需改動。在啟用虛擬網(wǎng)關(guān)后，F(xiàn)emto網(wǎng)關(guān)在邏輯上分割成多個獨立的信令實體，每個實體與不同地市的MSC/SGSN建立信令連接。HMS基于TR-069協(xié)議對HNB進行自動配置，在HNB加電后，HMS會將所有用戶開戶數(shù)據(jù)下發(fā)給HNB，也可對其進行批量軟件升級等。 2010 Cisco and/or its affiliates.
