This update added new revisions after undoing existing revisions. That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this:

* -- * -- B -- O -- O -- O (575301ae326141af5745b60e286054448b6f1723) \ N -- N -- N (75bfa56be9aa9fe98e88278e3a58ade29c2d69f0)

When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B.

Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below.

hack: Accept also UE_Identity_PR_pTMSIRAI in HNBAP from nano3G

I have the feeling that the nano3G simply forwards whatever identity it receives from the MS in RRC via HNBAP, without sending any IDENTITY REQUESTS by itself. That seems like a violation of the RANAP specification, but well.

As opposed to Neels' earlier commit, the phone I was testing with (GT-I9100) is using the UE_Identity_PR_pTMSIRAI (PS identity) instead of UE_Identity_PR_tMSILAI (CS identity) when trying its first attempt to register to the network, so let's support that equally.

hack: simply accept UE Register Requests with TMSI

HNBGW would usually keep track of UEs that have registered, with their IMSI. When a UE registers with only a TMSI, we obviously can't store an IMSI. However, since we're so far never *using* the list of UEs in osmo-hnbgw, we might as well just accept the TMSI registration and carry on as usual.

This is particularly helpful with an ip.access nano3G femto cell, as it tends to send UE registrations with a TMSI+LAI identification instead of an IMSI when the subscriber is known. This causes timeouts of several minutes until a UE registration switches back to IMSI. When simply accepting the TMSI in osmo-hngw, no problems are apparent in our current code state.

We could use the subscriber list during paging, but on the other hand, it doesn't hurt to anyway always page to all HNBs connected to osmo-hnbgw. The paging procedure does include a page-to-all-HNBs in case the first HNB paging fails. However, since we're now failing to record UEs that register by TMSI, we must be aware that trying to page such UE on only its last seen HNB will fail; it is plainly missing in the list.

UE Register with TMSI: reply with a Register Reject

When receiving a UE Register Request with TMSI and no IMSI, compose a Register Reject with the same UE Identity and send.

The accepting function expects a ue_context argument and composes the message from the IMSI found there. This new rejection message cannot rely on a ue_context struct and hence uses the asn1 uE_Identity directly.
