Common Control Channel Handling
Page mode extended makes it possible for the RBS to transmit pagings
(IMSIs or TMSIs) or immediate assigns for a certain paging group
when the next but one paging group is scheduled /GSM:04.08:3.3.2.1/.
The "Page Mode" element (of the PAGING_REQUEST or
IMMEDIATE_ASSIGNMENTs messages), set to extended Paging, is
sent as an indication to the MS to be prepared to handle extended
Paging as described above. The allowed use of extended page mode is
defined (in percentage) by means of configuration parameter
DRX_DEV_MAX, see MAX, see section Administration below.
On receipt of an IMMEDIATE_ASSIGN_COMMAND* with page
mode set to Paging reorganization, RBS uses Page Mode "Paging
reorganization" in all of the following air interface messages:-
IMMEDIATE ASSIGNMENT-IMMEDIATE ASSIGNMENT
REJECTED-IMMEDIATE ASSIGNMENT EXTENDED-PAGING
REQUEST 1–3, including dummy paging.
TRS uses Page Mode "Paging reorganization" until an IMMEDIATE
ASSIGNMENT COMMAND* message is received with page mode set
to normal paging or extended paging. The TRS then swaps page mode
from "Paging reorganization" to normal operation, which means that
normal paging or extended paging is used.
If an IMMEDIATE_ASSIGN_COMMAND* is received with page
mode set to ’Same as before’ the page mode is not changed.
Note: It should be made clear that it is the L3 immediate assign
message carried within the
IMMEDIATE_ASSIGN_COMMAND that contains the page
mode parameter.
Retransmission of Messages
A copy of a transmitted IMSI, TMSI and IA is stored for retransmission
(IARs are not stored for retransmission).
An IMSI or TMSI, or an IA stored for retransmission is discarded,
depending on the setting of parameter BS_PA_MFRMS (see section
Administration below) as specified below:
• BS_PA_MFRMS < = 3
−
The IMSI/TMSI/IA is discarded if it has not been
retransmitted within two schedulings of its paging group
• BS_PA_MFRMS > 3
− The IMSI/TMSI/IA is discarded if it has not been
retransmitted within one scheduling of its paging group
No message is retransmitted more than once. An IA is discarded if it
has not been retransmitted within 80 ms. The BSC may turn the
retransmission function on and off by means of configuration parameter
CCCH options/CR, see section Administration below.
