请问哪位大侠知道，BSC发Clear Request消息携带为MS not equipped的原因值，可能是什么原因引起的？我查了0408的文档，里面我没有搜索到MS not equipped的任何信息。请指教，谢谢了。

经过我近几天的研究，基本搞清楚了。首先这个信令是A口信令，不是空口信令，因此不能到0408中查（0408是空口的标准）。要到48.008中查（A口标准），下面是关于MS not equipped的解释，没有再具体的了，还与各个厂家在具体实现时有关。
3.1.18.1.2 MSC to MS Direction
Receipt of a layer 3 (DTAP) message from the MSC with the SAPI (indicated in the DLCI) not equal to "0" will cause one of the following actions:
- the triggering of a data link set up to support the message transfer across the radio interface if no suitable link exists;
- the transmission of the message to the MS if a suitable link has already been established;
- the sending of a BSSMAP SAPI "N" REJECT message to the MSC if for any reason the data link cannot be established, A Cause Information Element is included; typical Cause values are: "O&M intervention", "processor overload", "BSS not equipped", "MS not equipped".
