Timer T3240 and Timer T3241

Timer T3240 is started in the mobile station when:

- the mobile station receives a LOCATION UPDATING ACCEPT message completing a location updatingprocedure in the cases specified in subclauses 4.4.4.6 and 4.4.4.8;

- the mobile station receives a LOCATION UPDATING REJECT message in the cases specified insubclause 4.4.4.7;

- the mobile station has sent a CM SERVICE ABORT message as specified in subclause 4.5.1.7;

- the mobile station has released or aborted all MM connections in the cases specified in 4.3.2.5, 4.3.5.2, 4.5.1.1,and 4.5.3.1.

Timer T3240 is stopped, reset, and started again at receipt of an MM message.

Timer T3240 is stopped and reset (but not started) at receipt of a CM message that initiates establishment of anCM connection (an appropriate SETUP, REGISTER, or CP-DATA message as defined in 3GPP TS 24.008, 3GPP TS24.010 [21] or 3GPP TS 24.011 [22]).

Timer T3241 is started in the mobile station when entering MM state RR CONNECTION RELEASE NOTALLOWED.

Timer T3241 is stopped and reset (but not started) when the MM state RR CONNECTION RELEASE NOTALLOWED is left.

If timer T3241 expires, the MS shall abort the RR connection and enter the MM state MM IDLE.

NOTE 1: The value of this timer is used if the network does not indicate another value in a GMM signallingprocedure.

NOTE 2: The default value of this timer is used if neither the MS nor the Network send another value, or if theNetwork sends this value, in a signalling procedure.

NOTE 3: Typically, the procedures are aborted on the fifth expiry of the relevant timer. Exceptions aredescribed in the corresponding procedure description.

NOTE 4: The purpose of this timer is to prevent the MS from repeating the SERVICE REQUEST message withservice type data too early in case the request to setup the radio access bearer is queued by the radio accessnetwork.

NOTE 5: In Iu mode, the default value of this timer is used if the network provides a value for this timer in anon-integrity protected Iu mode GMM message.

NOTE 6: The value of this timer may be provided by the network to the MS in the ATTACH ACCEPT messageand ROUTING AREA UPDATE ACCEPT message. The default value of this timer is identical to the value oftimer T3312.

NOTE 1: The network may already have applied an internal alerting supervision function; e.g. incorporatedwithin call control. If such a function is known to be operating on the call, then timer T301 is not used.

NOTE 2: These time values are set by the network operator.

NOTE 3: When applied to the supplementary service CCBS, the timer T334 can either represent the recall timerT4 or the notification timer T10 (see 3GPP TS 23.093 [88a]). Thus the timer T334 can take two different values.3GPP TS 23.093 [88a] defines the range of these values.
