EPS User State can contain two variable something like 

EPS-User-State ::= < AVP header:1495 10415 >
                    [ MME-User-State ]
                    [ SGSN-User-State ]
                   *[ AVP ]

//contain the information related to the user state at MME.
MME-User-State ::= < AVP header: 1497 10415 > 
                    [ User-State ]
                   *[ AVP ]

 //contain the information related to the user state at SGSN.
SGSN-User-State ::= < AVP header: 1498 10415 > 
                     [ User-State ]
                    *[ AVP ]
