GSM：CM Service Request 深度学习
平时只是关注CM业务请求，只是在DT测试、分析的时候关于此信令，但是对于此信令里面的具体内容造诣还是不够深，希望高手、前辈指点。
语音业务、短信业务、彩信业务怎么区分？

在楼主给出的内容中包括了对服务类型的说明。
CM service type
Service type : (1) Mobile originating call establishment or packet mode connection establishment
这里说的是UE主动发起的始呼业务MOC。
至于这个始呼是12.2k的语言业务还是64k的VP业务（视频电话）则要看随后的setup信令中的内容，如果是12.2k的语言业务，则setup中会给出speech。如果是VP业务则给出的是速率未受限的CS业务的说明。
