Be able to tune the RACH settings of the BTS via the vty interface,
by default they are initialized to -1 which means we will use the
content of the static array (BTS default) and can be changed via
the VTY interface. I have verified the setting on the nanoBTS with
wireshark and I have tested writing the config file.

Only page if we have a load that is acceptable for paging. This
option is off by default, and can be enabled per bts. The idea
is that when we have no resources right now we will not page as
it will only create more RACHs and increase the load.

Implement a method to count the number of pending paging requests
per bts and print it on the VTY. This helps to see how big the
backlog of requests is for a given BTS.

This causes some config file breakage but sounds like a much cleaner
approach than to have two separate config variables for this.

According to TS 08.18, BVCI=0 is for the SIGNALLING entity,
and BVCI=1 is for the PTM entity. Both should not be used
by the PTP entity that we're configuring here.

Move the statistics command into the MSC part and move the
BSC statistics printing into a subroutine.

This is addressing multiple issues regarding the loss of the
OML/RSL link to the BTS.
1.) When we lose the OML link, close down all RSL connections
on all TRXs (only tested with one TRX) and free the e1inp_line
allocated for the OML connection.
2.) When we lose the RSL link on any TRX and we know to which
lines this connection belongs, we will close down the OML connection
as we have a problem to just reactivate the RSL link.
3.) When we lose the RSL link on any TRX and we do not know
where it belongs to we will free the bfd we have allocated in the
rsl listen/accept method and we properly close the socket (i could
not test this one properly).
4.) When we already have a bts->oml_link we will throw it away
and use the new link.

The code had wrong documentation in the VTY, it crashed
when OML or RSL was not up yet. These issues are fixed
right now.
|
|
I moved the extra code to the layer3 VTY implementation but didn't
remove the variables while doign so, silent compiler warnings.

We need to simulate OML/RSL failure in an easy and fast way
and adding a command to do so seems like a good way to achieve
this. The command is a bit misplaced, in one way it is no config
and does not belong into the config node but then again it does
not belong into the VIEW_NODE either as it is manipulating content.

We are storing the bound_ip in host byteorder but when
using ntohl we need to convert it back to to network
byte order.

Currently vty_interface.c is used for the BSC config, in case of
the MGCP Gateway or the BSC Nat process these logging commands are
not available. Move the commands to a new vty_interface_cmds.c file
to allow to share basic commands across different programs.

The logging/debugging code is generic enough to move it into libosmocore
while keeping OpenBSC specific definitions in openbsc itself.
This commit uses the logging support present in libosmocore-0.1.2,
you will have to update your library to this version.
|
|
Prepare to split the BSC and the MSC part by putting the
MSC data for a connection into a "gsm_subscriber_connection"
struct and renaming the macros.
|
|
It is possible that the MSC is not sending the channel type it
needs for the operations it wants to do. Add a configuration option
to assign a TCH in case of paging any requests. It can be a good
idea to leave SDCCHs free for location updating requests.
|
|
Store the mapping from request to channel type in the GSM Network
struct as there is some policy involved with handling the request.
E.g. in a half rate network we don't want emergy calls to be getting
a TCH/F, or we want to have a different policy for early/late assignment
of phone calls.
Update the table when creating the network and when the neci is changed.
|
|
Keep a static version as the shell script is not dealing well
with branch tags/names containing text.
Resolve merge conflict in the Makefile.am by adding both sides

This new gprs-conf branch is intended to contain everything needed
to configure GPRS in the nanoBTS, but without implementing the SGSN/GGSN
functionality.
The SGSN/GGSN development will happen in a branch based on this branch
called "gprs-sgsn"

This library is intended to collect all generic/common funcitionality
of all Osmocom.org projects, including OpenBSC but also OsmocomBB
The library currently includes the following modules:
bitvec, comp128, gsm_utils, msgb, select, signal, statistics, talloc, timer,
tlv_parse, linuxlist
msgb allocation error debugging had to be temporarily disabled as it depends on
'debug.c' functionality which at the moment remains in OpenBSC
|
|
We will use this token to identify us at the MSC for
now. This assumes that something like OpenVPN is already
used to secure the networking. In the future we will
explore using TLS for the communication and certificates
for the authentication.

Some NM attributes are defined differently depending on
the BTS type. Having one big nm_att_tlvdef[] table for
all BTS types is no longer sufficient. This patch
* introduces 'struct gsm_bts_model' to describe a BTS model
* adds definitions of gsm_bts_model for BS-11 and nanoBTS
* changes the abis_nm_tlv_parse() function: include a bts pointer
|
|
Currently "write memory" will not store the rtp_base_port of the
network. Fix that by writing it out in write_net. Also set it to
4000 by default in the MGCP and in the BSC.
|
|
Do not warn if the user has put "handover 0" in his configuration
as this will not enable handover, only warn if it is going to be
enabled.

* Be able to have a country code in the air but use a different
country code when talking to the core network.
* Now both country and network code can be different on air and
on the MSC communication.

Follow up on 424c4f0e2927d5a7538b31c69113c6e4f861d2c9. As pointed out
by Sylvain on the mailinglist I need to remove this here as well.
Do not call db.c code from code that is located in libbsc.a
|
|
vty_interface.c is part of libbsc.a but it started to use code
which is found in db.c recently. Fork the subscriber dumping and
provide more information on the layer3+ (MSC) commands. This
is restoring the separation again.
|
|
* Make it possible to have a different MNC in the RSL traffic
than in the core network.
* Introduce the "core network code NUMBER" variable. If it is
set this network code will be used in traffic with the MSC.
* Use the core_network_code number when sending a packet to
the MSC
* Regenerate the LAI (this is where I could have a bug) when
sending packets to the BTS.
* Add size checks.
This is not tested, I might got something wrong.

Also, use this new function to dump lchan state on VTY and to
improve readability of RSL log messages.
