In the field, we've encountered a so far unsupported scenario: after a RAB Assignment Request and Response have successfully set up an RTP stream, the CN sends *another* RAB Assignment Request to modify some SDU parameters, omitting the transportLayerInformation IE (not modifying the RTP address). Detect a secondary RAB Assignment Request, and just forward it as-is: the hNodeB is interested in the RAB configuration, osmo-hnbgw just needs the RTP info, which is not even present in this use case. Do not (yet?) support modifying the RTP address/port. Related: osmo-ttcn3-hacks Iadaba0e5e82ad6d163ad509904ede213e2462d5c Related: SYS#6624 Change-Id: I25bf19981cd75a87a7ceb3382dae1ec626ae475c
osmo-hnbgw - Osmocom hNodeB Implementation
This repository contains a C-language implementation of a 3G Home NodeB Gateway (OsmoHNBGW). It is part of the Osmocom Open Source Mobile Communications project.
You can use it to interface Iuh-speaking Home NodeB (HnodeB), such as osmo-hnodeb or ip.access nano3g, to Iu-speaking MSCs and SGSNs.
The official homepage of the project is https://osmocom.org/projects/osmohnbgw/wiki
You can clone from the official osmo-hnbgw.git repository using
git clone https://gitea.osmocom.org/cellular-infrastructure/osmo-hnbgw
There is a web interface at https://gitea.osmocom.org/cellular-infrastructure/osmo-hnbgw
User Manuals and VTY reference manuals are [optionally] built in PDF form as part of the build process.
