* [layer23/mobile] Improvement and fixes of idle mode processAndreas Eversberg2011-07-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces cell re-relection. When camping on a cell, it scanns neighbour cells. If a 'better' cell is found, the cell is selected. If the cell is in a different location area, a location upating is performed under certain conditions. The 'better' cell depends on various informations that are broadcasted on the BCCH of a neihbour cell and of course the RX level. Most operators don't set these informations, so the 'better' cell depend on a better RX level for the same location area, or a much better RX level (6 dBm) at a different location area. There were many issues at the idle mode process that has been fixed. Expecially when moving, the state machines got stuck, so no more cell search was possible, or no further calls / location updating was possible. In order to see the process of cell selection, enter the VTY interface and enable the network monitor: enable monitor network 1 (where '1' is the instance of the MS) In order to see the current state of the processes, enter: show ms
* [layer23] Adding Quadband support and GSM 4x0 supportAndreas.Eversberg2011-05-291-0/+1
| | | | | | | | This makes it possible to use GSM 850 and PCS 1900 bands, as used in the US. The support relies on the phone hardware. Each band (900, DCS, 850, PCS, 480 and 450) can be enabled and disabled individually for each setting.

* [layer23] Added support for multiple MS instancesAndreas.Eversberg2010-11-131-1/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | To create another instance: 'ms <name> create' To remove an instance: 'no ms <name>' If no instance exists, 'ms 1' is created automatically on startup. Each instance can be enabled / disabled by using 'shutdown' or 'no shutdown'. Multiple instances may share the same layer2 socket (same phone hardware), but in this case only one instance can be enabled at the same time. This makes it much easier to select different settings without modifying them. A 'shutdown' initiates the IMSI detach procedure before shutdown is completed. A 'shutdown force' will immidiately shutdown. There is no need to restart the software anymore, if fundamental settings are changed. In this case, a 'shutdown' followed by a 'no shutdown' will do the job. If you already have an old osmocom.cfg, you need to "no shutdown" it. Everything else behaves as before.
* [layer23] Fixed security issueAndreas.Eversberg2010-08-291-0/+1
| | | | | Authentication must not be performed using SIM client, if different IMSI is used, to protect identity of caller.
* layer23: Split [2/2] -> The header filesSylvain Munaut2010-07-271-0/+228
This split the headers and adapt the source. We use osmocom/bb as a prefix because libosomore also uses osmocom and generic names such as misc & common could conflict in the future. Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
