On Abis interface, it is contained in IMM ASS CMD message. It contains
complete ‘immediate assignment’ message and where the ‘paging mode’
unit is set as ‘unchanged’. On receiving this message, FURRM sends it to
PAGCHMan sub-module of PAGCHM module. It places the message in the
buffer. On receiving the trigger from ISR, the PAGCHDaemon, sub-module
of PAGCHM module, forms the messages in the waiting queue into the (RR)
IMMEDIATE ASSIGNMENT EXTENDED or (RR) IMMEDIATE ASSIGNMENT
REJECT message. It sends these messages to CHP. Before sending, OB06
changes the 'paging mode'.
If BSC cannot assign channel, it sends (RR) IMMEDIATE ASSIGNMENT
REJECT using the same CCCH time slot of the same channel on which it
received.
If the downlink CCCH is overloaded, FURRM sends the DELETE IND
message to BSC, notifying that it has deleted IMM ASS CMD command.
