[@boyandikasimbolon]

in minute 2:03 you said that PDN Connectivity Req Message is inside of ESM, but then why you said it embedded in EMM in minute 8:45 ? which on is correct ?

[@lteplusplus1225]

"PDN Connectivity Request" is a type of ESM message. Other examples of ESM messages are "ACTIVATE DEFAULT EPS BEARER CONTEXT REQUEST/ACCEPT". ESM messages could be embedded in ESM message. Some times standalone ESM messages are also used in LTE.
