Neels Hofmeyr 8eefcbee92 UE state leak: when HNB re-registers, discard previous UE state User reports show leaked UE contexts over time, in a scenario where HNB regularly disconnect and reconnect. So far, when we receive a HNB REGISTER REQ, we log as "duplicated" and continue to use the hnb_context unchanged. But it seems obvious that a HNB that registers does not expect any UE state to remain. It will obviously not tear down UE contexts (HNBAP or RUA) that have been established before the HNB REGISTER REQUEST. These hence remain in osmo-hnbgw indefinitely. When receiving a HNB REGISTER REQUEST, release all its previous UE state. Allow the HNB to register with a clean slate. The aim is to alleviate the observed build-up of apparently orphaned UE contexts, in order to avoid gradual memory exhaustion.

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.
