and paging channel gain, etc. If these parameters are not properly
set (for example: they are set too low), the MS will not be able to
capture the common channel and thus will not be able to connect to
the network.
With the help of Abis-interface message tracing tool, find out
whether the gain parameters carried in the Abis-Cell Setup message
are correct, if not, reconfigure the BSC data configuration table.
VIII.
Check overhead message
If we can see from the OMC console the logic configuration for
the cell has been completed, but the MS still can not connect to the
network, we can then check whether the overhead message is
correct.
When the MS enters the idling status, it needs to receive all the
overhead message set up by the system, which include at least the
following five:
The synchronization message, access parameter message,
system parameter message, CDMA channel list message, Neighbor
List Message. Other overhead message may vary with the network
parameter settings.
If any one of the above system messages is not received, the
MS will not be able to connect to the network.
Additionally, the value setting in each of the parameters in the
message will directly affect the MS network connection, therefore
please be careful.
