Hi Community,
Does anyone successfully run a 3G network using OSMOCOM elements?
The main obstacle is 3G voice, as has been discussed numerous times lately. Only 3G<->3G voice works, because we cannot unmangle the IuUP of 3G voice yet. Will not work: transcode to a PBX or interop with 2G.
Mykola recently expressed interest in implementing that, but it remains an open issue, desirable to be solved, but yet unfunded.
Currently we are trying to run the following OSMO elements using this URL "https://osmocom.org/projects/cellular-infrastructure/wiki/Osmocom_Network_In....
Instead of using a 3G femto cell as HnodeB
We have the nano3G and the SysmoCell5000 series sold by sysmocom.
Is there other software that will act as HnodeB between the SDR and OSMOHNBGW?
The point is that an hNodeB contains an RNC that we happily use. There is no free/open source RNC available apparently, so that is considerable development effort.
Expressed in 2G terms, it is as if the osmo-bsc were missing.
does anyone tried to use UMTRX, B210, and LimeSDR?
It's not a question of "try", the point is that there is no 3G capable phy to drive the SDR with.
In 2G terms, it is as if osmo-bts-trx were missing.
Anyone willing to invest time there is more than welcome. It is a considerable effort though.
