Common Control Channel Handling
• The CCCH queue system is used for system information 7, 8, 13,
16 and 17 for transmisstion on BCCH extended.
IMMEDIATE_ASSIGNMENT messages:
The queues are handled in a FIFO (First-In-First-Out) manner when the
following messages are composed:
• IMMEDIATE_ASSIGNMENT
• IMMEDIATE_ASSIGNMENT_EXTENDED (first IA)
• IMMEDIATE_ASSIGNMENT_REJECT (first IAR)
PAGING_REQUEST messages:
The queues are handled in a FIFO manner when the first IMSI or TMSI
intended for a PAGING REQUEST message is dequeued.
Packing of Messages
IMMEDIATE_ASSIGNMENT messages:
If possible, two IAs (queued or stored for retransmission) will be
packed into one IMMEDIATE_ASSIGNMENT_EXTENDED message.
If Extended paging is used, IAs originating from two different paging
groups may be packed into the same
IMMEDIATE_ASSIGNMENT_EXTENDED message.
A maximum of four unique IARs can be packed into one
IMMEDIATE_ASSIGNMENT_REJECT message.
If Extended paging is used, IARs originating from different paging
groups may be packed into the same
IMMEDIATE_ASSIGNMENT_REJECT message.
PAGING_REQUEST messages:
As many IMSIs and TMSIs as possible (for a certain paging group) will
be packed into one PAGING_REQUEST message (type 1, 2 or 3). If
Extended paging is used (see section Selection of Page Mode below),
IMSIs and TMSIs originating from two different paging groups may be
packed into the same PAGING_REQUEST message.
IMSIs and TMSIs stored for retransmission (in the corresponding
paging stack) are included in the PAGING_REQUEST message if not
enough IMSIs or TMSIs are found in the actual paging queue.
Selection of Page Mode
The RBS selects the appropriate Page mode value /GSM:04.08:-
10.5.2.26./ for each message. The following Page modes are used:
• Normal
• Extended
• Paging reorganization
The allowed use of extended page mode is configured (as a percentage)
on command from the BSC. This is done by means of configuration
parameter DRX_DEV_MAX, see section Administration below.
