MIH protocol header format
srho

10. MIH protocol header format
Version: version of MIH protocol used (0: Not to be used/ 1: First version/ 2-15: (Reserved))
ACK-Req: requesting an acknowledgement for the message
ACK-Rsp: responding to the request for an acknowledgement for the message
UIR (Unauthenticated Information Request): Indicates if the protocol is sent in pre-authentication/ pre-association state
M (More fragment)
FN (Fragment Number)
MIH Message ID (MID)
SID (Service identifier): 1Service Management/ 2 Event Service/ 3 Command Service/ 4 Information Service
Opcode (Operation code): 1Request/ 2Response, 3Indication
AID (Action identifier): Indicates the action to be taken with regard to the SID
Transaction ID: matches Request and Response, as well as matching Request, Response and indication to an ACK
