{{>toc}} h1. OsmoCBC This is the upcoming Osmocom Cell Broadcast Centre. h2. Introduction You can find more information about Cell Broadcast in general at [[cellular-infrastructure:Cell_Broadcast]] and [[cellular-infrastructure:Service_Area_Broadcast]], as well as [[cellular-infrastructure:Emergency_Warning]] and [[cellular-infrastructure:Public_Warning_System]]. The pages include pointers to the relevant specifications. h2. Position in the network The below graph shows the CBC in the network. {{graphviz_link() digraph G { rankdir = RL; CBC [color=red]; CBE -> CBC [label="REST/JSON"]; CBC -> BSC [label="CBSP"]; CBC -> RNC [label="SABP"]; CBC -> MME [label="SBc-AP"]; BSC -> BTS [label="A-bis RSL"]; RNC -> NodeB [label="Iub"]; MME -> eNodeB [label="S1-AP"]; BTS -> UE [label="CBCH"]; NodeB -> UE [label="BMC/CTCH"]; eNodeB -> UE [label="SIB10/11/12"]; } }} As can be seen, the CBC receives messages from third-party applications (called CBEs). It then routes/distributes/forwards those messages over the respective radio access technology specific method. h2. History FIXME. {{include(cellular-infrastructure:MacroBinaryPackages)}} h2. Manuals FIXME h2. Source Code The source code is available from @git.osmocom.org@ (module @osmo-cbc@). Public read-only access is available via <pre> git clone git://git.osmocom.org/osmo-cbc.git </pre> You can browse it via cgit: https://git.osmocom.org/osmo-cbc Contributions are welcome via [[cellular-infrastructure:Gerrit]]. h2. Test Suite We have a TTCN-3 test suite as part of our [[cellular-infrastructure:Titan_TTCN3_Testsuites]] * source code: http://git.osmocom.org/osmo-ttcn3-hacks/tree/cbc?h=laforge/cbsp * results: [not yet automatically executed] h2.
