Node B的邏輯模型由小區(qū)，公共傳輸信道及其傳輸端口、 Node B通信上下文及其對應的 DSCH、DCH 等端口； Node B 控制端口 NCP；通信控制端口 CCP 等幾部分組成。 ? Node B 通信上下文及其對應的 DSCH、 DCH 端口屬于與特定用戶業(yè)務相關的部分。 ? Node B 通信上下文同 CRNC 通信上下文對應。 ? Node B 通信上下文由 Node B Communication Text ID 來標識，包含了同 UE 通信的必要信息。由 RL Setup 過程建立，在 RL delete 時刪除。 ? 一個 Node B 上僅有一條 NCP 鏈路， RNC 對于 Node B 所有的公用的控制信令都是從 NCP 鏈路傳送的。在對于 Node B 進行任何操作維護控制之前，一定先要建立這條鏈路。 ? 一個 Node B 可以有多條 CCP 鏈路， RNC 對于 Node B 所有的專用的控制信令都是從 CCP 鏈路傳送的。一般情況下， Node B 內的一個 CELL 配置一個通信控制端口 CCP（這種配置方式只是一個慣例，并不確定）。 321 NBAP 過程 ： Table 6: Class 1 Elementary Procedure Message Successful Oute Unsuccessful Oute Response message Response message Cell Setup CELL SETUP REQUEST CELL SETUP RESPONSE CELL SETUP FAILURE Cell Reconfiguration CELL RECONFIGURATION REQUEST CELL RECONFIGURATION RESPONSE CELL RECONFIGURATION FAILURE Cell Deletion CELL DELETION REQUEST CELL DELETION RESPONSE Common Transport Channel Setup COMMON TRANSPORT CHANNEL SETUP REQUEST COMMON TRANSPORT CHANNEL SETUP RESPONSE COMMON TRANSPORT CHANNEL SETUP FAILURE Common Transport Channel Reconfiguration COMMON TRANSPORT CHANNEL RECONFIGURATION REQUEST COMMON TRANSPORT CHANNEL RECONFIGURATION RESPONSE COMMON TRANSPORT CHANNEL RECONFIGURATION FAILURE Common Transport Channel Deletion COMMON TRANSPORT CHANNEL DELETION REQUEST COMMON TRANSPORT CHANNEL DELETION RESPONSE Physical Shared Channel Reconfigure [TDD] PHYSICAL SHARED CHANNEL RECONFIGURATION REQUEST PHYSICAL SHARED CHANNEL RECONFIGURATION RESPONSE PHYSICAL SHARED CHANNEL RECONFIGURATION FAILURE Audit AUDIT REQUEST AUDIT RESPONSE AUDIT FAILURE Block Resource BLOCK RESOURCE REQUEST BLOCK RESOURCE RESPONSE BLOCK RESOURCE FAILURE Radio Link Setup RADIO LINK SETUP REQUEST RADIO LINK SETUP RESPONSE RADIO LINK SETUP FAILURE System Information Update SYSTEM INFORMATION UPDATE REQUEST SYSTEM INFORMATION UPDATE RESPONSE SYSTEM INFORMATION UPDATE FAILURE Common Measurement Initiation COMMON MEASUREMENT INITIATION REQUEST COMMON MEASUREMENT INITIATION RESPONSE COMMON MEASUREMENT INITIATION FAILURE Radio Link Addition RADIO LINK ADDITION REQUEST RADIO LINK ADDITION RESPONSE RADIO LINK ADDITION FAILURE Radio Link Deletion RADIO LINK DELETION REQUEST RADIO LINK DELETION RESPONSE 322 Elementary Procedure Message Successful Oute Unsuccessful Oute Response message Response message Synchronised Radio Link Reconfiguration Preparation RADIO LINK RECONFIGURATION PREPARE RADIO LINK RECONFIGURATION READY RADIO LINK RECONFIGURATION FAILURE Unsynchronised Radio Link Reconfiguration RADIO LINK RECONFIGURATION REQUEST RADIO LINK RECONFIGURATION RESPONSE RADIO LINK RECONFIGURATION
