* new abis_nm_bs11_bsc_disconnect() function to disconnect BSC/BTS link
* add support for 'forced load' of BS-11 software to abis_nm.c and bs11_config
* remove lots of debug output
* print progress during software load
* add more BS11 specific attributes
* define all valid BS11 PA power classes
* add callback function to software load
* introduce SWL load function for BS-11 style SWL file lists
* separate activation of software from loading of software
* add function to obtain BS-11 serial number
* disable serial port POST processing
* default delay is 0
* make window size user-configurable (default: 8)
* add missing help line for the --delay option
* don't forget to create the CCLK object as part of minimal config
The TMSI encoding is up to us but generate_mid_from_tmsi and mi_to_string
did not agree on the encoding. Adjust mi_to_string to properly decode the
TMSI generated by generate_mid_from_tmsi. Check that the four bits are '1111'
and that the length is five. Memcpy the bytes to tmsi (to work with ARM or such)
and convert the number to host order...
Implement the CM Service Request. Try to get the subscriber from the TMSI and
assign it to the gsm_lchan. There is a small issue that will be fixed in the
next commit.
(done by z.)
Be able to send Accept/Reject the Service Request. Use mi_string
instead of the the msgb buffer (even if it is memsetted and such)...
The TMSI allocation seems to be a bit problematic and needs some
further checking. The rough idea is that we try to find the subscriber
for a CM Service Request and then decide based on the subscriber
if we want to handle the call.
It is possible that the BTS is closing the channel even when
our upper layers are doing work. Reset the use_count add a fixme
to call cancellations for pending operations. Cancellation of the
call state (state machines in general) and such come into mind...
Increase when the refcount of the lchan when we initiate a call,
get a SETUP message and put it when we want to release the call...
Once we have proper Q.931 support the use/put needs to be improved,
e.g. we currently do not allow to hangup from the network, and it
will ring until the end of time...
Wrote and test code to add and remove paging requests... This
will be using the fact that the linux list is building a circle
on each tick we can send one/x paging requests and continue round
robin...
You can request to open a channel to a MS and the paging layer
will call you once the channel is allocated. Internally the CCCH
Load Indication will be handled and retry to page a terminal.
It looks like that certain phones that send their old TMSI from
a different network and we assign them a new one with LOCATION
UPDATING ACCEPT will send us a TMSI Reallocation Complete. Print out
the the imsi.
