楼主看24301.
这两个信令是NAS层信令,并且明确说明要一起发。
The UE shall send the ATTACH REQUEST message together with a PDN CONNECTIVITY REQUEST message contained in the ESM message container information element to request PDN connectivity.
NAS是RRC上层吧?RRC是否会把payload分开发?这个俺不清楚。

36.331描述
A UE in RRC_CONNECTED initiates the UL information transfer procedure whenever there is a need to transfer NAS or non-3GPP dedicated information, except at RRC connection establishment in which case the NAS information is piggybacked to the RRCConnectionSetupComplete message.
跟RRC CON CMP一起发的可能是有的,应该不会跟req一起发。
