Common Control Channel Handling
Dummy Paging
Whenever no PAGING_REQUEST or IMMEDIATE_ASSIGNMENT
message is scheduled for transmission in a CCCH block, a Dummy
Paging message is used.
The message used for Dummy Paging is a PAGING_REQUEST type 1
/GSM:04.08:9.1.22./.
Administration
The following configuration parameters are used to control the
transmission of PAGING_REQUEST messages and
IMMEDIATE_ASSIGNMENT messages on downlink CCCH:

22.2.5 Channel Request by MS
By means of the CHANNEL REQUEST BY MS procedure /
GSM:08.58:5.1./, the RBS detects channel requests (random accesses)
from MSs, and reports these as CHANNEL_REQUIRED messages to
BSC.
The RBS supports:
•
•
The channel request is coded as AB (access bursts) /GSM:05.02:5.2.7./
and /GSM:05.03:4.6./.
The RBS observes the TDMA frame number and measures the access
delay of the AB arrival.
If the rate of CHANNEL_REQUESTs is higher than specified in the
section Operational Conditions below, messages may be temporarily
stored before transmission to the BSC. Messages not transmitted within
234 (485)
