Section: 4.1.1.2.2 GPRS MS operating in mode A or B in a network that operates in mode II
Content: If the network operates in mode II, a GPRS MS that operates in mode A or B and wishes to be or is simultaneously IMSI attached for GPRS and non-GPRS services, shall use the MM specific procedures listed in subclauses 4.3 and 4.4 and the GMM specific procedures listed in subclauses 4.7.3, 4.7.4 and 4.7.5. The applicability of periodic location updating is further specified in subclause 4.4.2 and the periodic routing area updating is specified in subclause 4.7.2.2. If the GPRS MS, which operates in mode A or B, wishes to be IMSI attached for GPRS and "SMS-only service"or is simultaneously IMSI attached for GPRS and non-GPRS services in order to obtain GPRS services and "SMS-only service", then the GPRS MS shall first complete the GMM specific procedure before performing the MM specific procedures. If this GPRS MS receives in the ATTACH ACCEPT or ROUTING AREA UPDATE ACCEPT message the Additional network feature support IE indicating "SMS via GPRS supported", then the GPRS MS shall not perform the MM specific procedure until a new ATTACH ACCEPT or ROUTING AREA UPDATE ACCEPT message indicating "SMS via GPRS not supported" or the GPRS MS does not wish to be IMSI attached only for GPRS and "SMS-only service". If the authentication procedure is performed by MM and the authentication is rejected by the network (i.e upon receive of AUTHENTICATION REJECT), the MS shall in addition set the GPRS update status to GU3 ROAMING NOT ALLOWED and shall, if available, delete the P-TMSI, P-TMSI signature, RAI and GPRS ciphering key sequence number stored. The SIM/USIM shall be considered as invalid for GPRS and non-GPRS services until switching off or the SIM/USIM is removed. The MS shall abort any GMM procedure and shall enter state GMM-DEREGISTERED. If S1 mode is supported in the MS, the MS shall handle the EMM parameters EPS update status, GUTI, last visited registered TAI, TAI list and KSI as specified in 3GPP TS 24.301[ Non-Access-Stratum (NAS) protocol for Evolved Packet System (EPS); Stage 3 ]  [120] for the case when the EPS authentication is not accepted by the network. If the PS or CS domain is barred because of domain specific access control, a GPRS MS operating in mode A or B in a network that operates in mode II shall use the MM specific procedures or GMM specific procedures, respectively, in the domain which is unbarred. If the MS detects that a domain changes from barred to unbarred, it shall behave as specified in subclauses 4.3.4.4, 4.4.4.9, 4.5.1.2, 4.7.3.1.5, 4.7.4.1.4, 4.7.5.1.5, and 4.7.13.5.
