access burst, whose content is the handover reference information unit.
The OB06 starts immediately the send on the active channel in specified
mode, with encryption if there is any encryption indication. If there are MS
mode, with encryption if there is any encryption indication. If there are MS
power and time lead, or only MS power, the OB06 will use the parameter
to start the send on SACCH. When the OB06 receives one access burst
with correct handover reference or one correct decoding frame, the OB06
to start the send on SACCH. When the OB06 receives one access burst
with correct handover reference or one correct decoding frame, the OB06
starts the normal receiving procedure on the active channel and SACCH,
and starts the handover detection procedure that is sent to the BSC. The
and starts the handover detection procedure that is sent to the BSC. The
measured access burst delay is contained in the HANDO DET message.
In asynchronous handover, when MS is connected to the allocated channel,
the first half procedure is the same as that in the synchronous handover
(see above). When the HANDO DET message is sent, the OB06 sends the
(see above). When the HANDO DET message is sent, the OB06 sends the
(RR) PHY INFO message to MS in non-acknowledgement mode on the
active signaling channel, and starts T3105 at the same time. If T3105
expires before a correct decoding frame is received, the message will be
active signaling channel, and starts T3105 at the same time. If T3105
expires before a correct decoding frame is received, the message will be
resent. If no correct decoding frame is received when the message has
been resent for Ny1 times, the OB06 will send to the BSC a CONNECTION
been resent for Ny1 times, the OB06 will send to the BSC a CONNECTION
FAILURE message with the cause “Handover access failed”. When the
message is received, the network side will disconnect the new channel. At

this stage, the RR session release procedure begins: Channel release and
link release.
link release.
Pseudo-synchronous cell: The procedure is the same as that in a
synchronous cell. When the bottom connection is established, the MS
returns a (RR) HANDOVER COMPLETE message (transparent) on the active
synchronous cell. When the bottom connection is established, the MS
returns a (RR) HANDOVER COMPLETE message (transparent) on the active
DCCH. If the bottom connection fails, the MS returns a HANDOVER
FAILURE message. When the message is received, the network side will

disconnect the new channel and enter the RR session release procedure.
The parameters T3105 and Ny1 are sent by the OAMM module to the
FURRM during the system initialization.
Remarks: Similar to the link establishment procedure, when a TCH
channel in the service mode is set up, it waits for a synchronization
