GSM T3126 Vs T3122

[peanut]

Dears,


When the MS receives an Immediate Assignment reject, it start two timers T3122 & T3126


could some one explain the difference and the relation between these two timers?
does MS start a cell reselection when receiving the reject?


B regards,

T3122: This timer is used during random access, after the receipt of an IMMEDIATE
ASSIGN REJECT message. Its value is given by the network in the IMMEDIATE
ASSIGN REJECT message.



T3126:This timer is started either after sending the maximum allowed number of
CHANNEL REQUEST messages during an immediate assignment procedure. Or on
receipt of an IMMEDIATE ASSIGNMENT REJECT message, whichever occurs first.
It is stopped at receipt of an IMMEDIATE ASSIGNMENTmessage, or an
IMMEDIATE ASSIGNMENT EXTENDED message. At its expiry, the immediate
assignment procedure is aborted. The minimum value of this timer is equal to the
time taken by T+2S slots of the mobile station's RACH. S and T. The maximum
value of this timer is 5 seconds
