MAP 协议分析培训教程内容提要：
备注（杜孝亲20060327）：
1、在补充业务中，存在MSC与SCP之间的MAP接口。名称没有。用于MSC向SCP上报用户的补充业务调用信息。当用户启用CD、ECT、MPTY补充业务时，MSC需要向SCP发送notification消息。具体何种消息由SS-CSI决定。参考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、在移动性管理中，存在VLR与SCP之间的MAP接口，名称没有，用于VLR向SCP上报用户的移动性相关notification消息。比如用户附着了，路由更新了，VLR会向SCP上报相关信息，此时采用的是MAP协议的消息。具体动作由M-CSI定义。－－参考23078第9章
