Common Control Channel Handling
16.2.2 Immediate Assign
By means of the IMMEDIATE ASSIGNMENT procedure /
GSM:08.58:5.7./, the network signals acceptance or rejection of a
CHANNEL_REQUEST message from MS.
The RBS supports:
•
Reception, interpretation and check of
IMMEDIATE_ASSIGN_COMMAND messages from BSC
• Queuing of IA (Immediate Assign) and IAR (Immediate Assign
Reject)
•
Scheduled transmission of IMMEDIATE_ASSIGNMENT
messages on AGCH (Access Grant CHannel)
• Retransmission of IMMEDIATE_ASSIGNMENT messages on
AGCH
IAs and IARs are queued for scheduled transmission on the AGCH.
The RBS supports one queue for IA messages and one for IAR
messages. The following messages are used for scheduled transmission
of IA and IAR:
•
IMMEDIATE_ASSIGNMENT /GSM:04.08:9.1.18/
•
IMMEDIATE_ASSIGNMENT_EXTENDED /GSM:04.08:9.1.19/
•
IMMEDIATE_ASSIGNMENT_REJECT /GSM:04.08:9.1.20/
For dequeuing, priority handling, selection of Page Mode, transmission
and retransmission, see Section 16.2.4 on page 169.
If two IAs are received in one IMMEDIATE_ASSIGN_COMMAND
message from the BSC, they will be queued together and sent after each
other.
16.2.3 Immediate Assignment Sent
By means of IMMEDIATE ASSIGNMENT SENT procedure the RBS
indicates to the BSC, if ordered, when an
IMMEDIATE_ASSIGNMENT or
IMMEDIATE_ASSIGNMENT_EXTENDED is sent on air interface.
The RBS supports handling of IMMEDIATE_ASSIGNMENT_SENT
messages.
In case the element "Mobile Identifier" is present in the
IMMEDIATE_ASSIGNMENT_COMMAND from the BSC, the
IMMEDIATE_ASSIGNMENT_SENT message is sent on Abis as soon
as the corresponding IMMEDIATE_ASSIGNMENT or
IMMEDIATE_ASSIGNMENT_EXTENDED message has been sent on
air interface. The following information is included:
• Element "Channel Number" indicating the channel on which the
IMMEDIATE_ASSIGNMENT or
IMMEDIATE_ASSIGNMENT_EXTENDED message was
transmitted on.
• Element "Mobile Identifier" as received in the
IMMEDIATE_ASSIGNMENT_COMMAND from the BSC.
