MAP 協議分析培訓教程內容提要：
備注（杜孝親20060327）：
1、在補充業務中，存在MSC與SCP之間的MAP接口。名稱沒有。用於MSC向SCP上報用戶的補充業務調用信息。當用戶啟用CD、ECT、MPTY補充業務時，MSC需要向SCP發送notification消息。具體何種消息由SS-CSI決定。參考23078第8章
The SS invocations that can be notified to the gsmSCF via this interface are Call Deflection (CD), Explicit Call Transfer (ECT) and Multi Party (MPTY).
CD:Call Deflection (CD) enables the served mobile subscriber to respond to an incoming call offered by the network by requesting redirection of this call to another number specified in the response. The CD supplementary service can only be invoked before the connection is established by the served mobile subscriber, i.e. in response to the offered call, or during the period that the served subscriber is being informed of the call.

2、在移動性管理中，存在VLR與SCP之間的MAP接口，名稱沒有，用於VLR向SCP上報用戶的移動性相關notification消息。比如用戶附著了，路由更新了，VLR會向SCP上報相關信息，此時采用的是MAP協議的消息。具體動作由M-CSI定義。－－參考23078第9章
